Description
Technical Field
The invention relates to the technical field of separation equipment, in particular to a novel air flow classification device for preparing ganoderma lucidum spore powder.
Background
The ganoderma lucidum spores are extremely tiny oval germ cells ejected from ganoderma lucidum fungus folds in the growth and maturation period, and because dust, soil powder, insect corpses and other impurities in the environment are inevitably collected together in the process of collecting ganoderma lucidum spore powder, the medicinal performance of the ganoderma lucidum spore powder is affected, and therefore the collected impurities in the ganoderma lucidum spore powder need to be separated.
The production plant of ganoderma lucidum spore powder uses air classifier to separate spore powder, in which the main working component of the air classifier is turbine (classifying wheel), on the turbine several blades are mounted, and formed into radial gap, and when it is working, the turbine can be rotated at high speed, the spore powder material mixed with impurity can be fed into classifying cavity by means of feeding pipe, then can be moved upwards along with rising air flow direction, and can be restricted by equipment and air flow direction, and can be passed through the gap of blades from outer circumference of the turbine, at the same time the rotation of turbine can make air flow and material in the air flow make circular movement so as to form centrifugal sedimentation process, the coarse particles, i.e. impurity can be settled into the inner wall of equipment in the outer circumferential direction, and fallen from centre of turbine, and the fine particles, i.e. spore powder can be discharged from centre of turbine so as to implement the goal of separating spore powder and impurity.
However, when the existing air classifier is used, the problem is that the treatment capacity of the classifier wheel is fixed, if the spore powder is excessively added in the classifying cavity, the concentration of the spore powder in the classifying cavity is high, the classifying operation of the classifier wheel is obviously unfavorable, the classifying effect is poor, and even the abrasion of the classifier wheel by the spore powder is aggravated, so that the performance of the classifier wheel is reduced; if the amount of the spore powder added into the classifying cavity is too small, the spore powder needs to be separated for a plurality of times in batches, the whole separation efficiency of the spore powder is obviously difficult to improve, and the low-concentration spore powder in the classifying cavity is difficult to enable the classifying wheel to exert the optimal classifying performance; if the amount of the spore powder added in the classifying cavity just accords with the processing capacity of the classifying wheel, the separated spore powder can be discharged out of the classifying cavity when the classifying wheel is used for classifying the spore powder, so that the concentration of the spore powder in the classifying cavity is continuously reduced, the classifying effect of the classifying wheel still can not be continuously maintained in the optimal classifying state all the time, namely, the spore powder in the classifying cavity is difficult to maintain in a constant value, and the classifying wheel is easy to maintain in an efficient running processing state.
Therefore, a novel airflow classifying device for preparing ganoderma lucidum spore powder is needed to solve the problems.

In order to prevent external impurities from falling into the classifying barrel 2 from the feed inlet to affect the classifying effect of the classifying barrel 6 in the working process of the classifying barrel 6, the sealing cover plate 32 is hinged to the feed inlet, and after the ganoderma lucidum spore powder is poured into the classifying barrel 2 from the feed inlet, the sealing cover plate 32 is covered, so that the external impurities such as dust can be prevented from falling into the classifying barrel 2.
Considering that the rising airflow in the classifying cylinder 2 is gradually reduced in the rising process, so that the spore powder carried by the airflow is less and less, and the processing capacity of the classifying wheel 6 is easy to reduce, in order to avoid the occurrence of the situation, the cross section of the classifying cylinder 2 is arranged in a trapezoid shape, namely the diameter of the classifying cylinder 2 along the length direction is smaller and smaller, so that the airflow is restricted by the flow direction of the airflow in the rising process, the momentum of the airflow is not lost too much, and the rising airflow is ensured to carry more spore powder to carry out classifying operation at the classifying wheel 6.
Specifically, the bottom of the classifying cylinder 2 is communicated with and fixed with an air inlet cylinder 4, the side wall of the air inlet cylinder 4 is provided with an air inlet along the tangential direction of the air inlet cylinder, an inclined upward air inlet pipe 41 is fixed at the air inlet, the end part of the air inlet pipe 41 is connected with a fan, continuous air flow is generated through the fan, under the guiding effect of the inclined upward air inlet pipe 41, the air flow can form an upward moving flow track, meanwhile, the air flow flowing in the air inlet cylinder 4 along the tangential direction of the side wall of the air inlet cylinder 4 can form a spiral ascending moving track along the cylinder wall of the air inlet cylinder 4, finally, the spiral ascending air flow carries spore powder to realize the aim of air flow classification, specifically, the classifying wheel 6 rotates and the air flow rotates, the spore powder rising to the classifying wheel 6 along with the air flow moves circularly, so that a centrifugal sedimentation process is formed, coarser impurity particles move to the outer circumferential direction until the inner wall of the classifying cylinder 2 loses speed and fall along the height direction of the classifying cylinder 2, and finer particles, namely the spore powder are discharged from the center of the classifying wheel 6 to the discharging outlet 3 to the discharging outlet from the charging cylinder.
Further, in order to improve the rotating effect of the air flow entering the air inlet barrel 4, the inner wall of the air inlet barrel 4 is provided with the spiral upward diversion trench 42, one end notch of the diversion trench 42 is the same as the air inlet, the other end notch of the diversion trench 42 is communicated with the classifying barrel 2, and when the air flow flows into the air inlet barrel 4, the air flow firstly flows along the direction of the diversion trench 42, so that the rotating effect of the air flow in the air inlet barrel 4 can be effectively improved, and the air flow entering the classifying barrel 2 can fully maintain the rotating and ascending flowing state.
The bottom of the air inlet cylinder 4 is communicated with and fixed with a discharge cylinder 5, the bottom of the discharge cylinder 5 is provided with a discharge opening so as to discharge dust, soil powder, insect corpse and other impurities separated from spore powder from the discharge opening, meanwhile, the air flow in the air inlet cylinder 4 is considered to be kept in a spiral upward running state all the time, in order to avoid the air flow reversely flowing out from the discharge opening, the air inlet cylinder 4 and the grading cylinder 2 are decompressed to cause the grading effect of the grading wheel 6 to be reduced, therefore, a rotary valve is fixedly arranged at the discharge opening, and the rotary valve rotates to discharge the impurities along with the rotation of blades of the rotary valve to the lower outlet, and meanwhile, the air flow in the air inlet cylinder 4 is ensured not to reversely flow out from the discharge opening, so that the stable running of the air flow grading device is effectively ensured.

The top of the feeding cylinder 3 is rotationally connected with a main shaft 8, the main shaft 8 sequentially passes through a conical hopper 31 and the bottom of a storage tank 7, the bottom of the storage tank 7 is fixedly connected with the surface of the main shaft 8, a plurality of connecting frames 21 are circumferentially arrayed on the inner wall of the bottom of the grading cylinder 2, the end parts of the connecting frames 21 are fixedly connected with a bearing seat together, one end of the main shaft 8 is rotationally connected with the bearing seat, and a driving piece for driving the main shaft 8 to rotate is arranged at the other end of the main shaft 8.
Considering that the collected spore powder is agglomerated due to the air humidity, the classification operation of the classification wheel 6 is not facilitated, and therefore, a pulverizing assembly for pulverizing the spore powder is installed in the storage tank 7.
Specifically, the crushing assembly comprises a conical grinding disc 9 fixedly connected with a main shaft 8, the top of a storage tank 7 is in a round table shape, the side wall of the conical grinding disc 9 is matched with the inner wall of the top of the storage tank 7, a plurality of arc-shaped guide grooves 91 are formed in the side wall of the conical grinding disc 9, the circumference of the guide grooves 91 are arrayed on the side wall of the conical grinding disc 9, notches at two ends of the guide grooves 91 are respectively communicated with a conical hopper 31 and the storage tank 7, the upper groove width of the guide grooves 91 is larger than the lower groove width, so that spore powder falling into the storage tank 7 firstly falls to the top of the conical grinding disc 9, meanwhile, the conical grinding disc 9 rotates along with the main shaft 8, so that the spore powder can fully flow into the guide grooves 91 under the action of centrifugal force, and under the structural constraint of the guide grooves 91, the agglomerated spore powder is mutually extruded and crushed in the guide groove 91 by the conical grinding disc 9 and the inner wall of the storage tank 7, so that the spore powder flowing out of the lower part of the guide groove 91 is scattered, the air flow is favorable for blowing the scattered spore powder to the classifying wheel 6 for classifying operation, and the method is different from the prior art that the spore powder is crushed in advance and is applied to a crusher, and obviously improves the separation cost of the spore powder due to higher manufacturing cost of the crusher.
Furthermore, in order to ensure that the classifying wheel 6 can always keep in a high-efficiency running state, a quantitative component for keeping the quantity of the spore powder in the classifying cylinder 2 constant is arranged below the crushing component in the storage tank 7, and the quantitative component is matched with the classifying cylinder 2 and the classifying wheel 6 to ensure that the classifying cavity in the classifying cylinder 2 can constantly keep quantitative spore powder, so that the problem that the classifying wheel 6 cannot run efficiently due to the fact that the spore powder content in the classifying cavity is low or the spore powder content in the classifying cavity is high during the working of the classifying wheel 6 is avoided, the condition that the classifying wheel 6 can keep full-load working for a long time is ensured, and the running efficiency of the air flow classifying device is effectively improved.
Specifically, the quantitative component comprises a supporting plate 81 fixedly connected with the main shaft 8 and a bearing plate 82 slidingly connected with the main shaft 8, a plurality of springs 821 are uniformly fixed at the top of the supporting plate 81, the other ends of the plurality of springs 821 are fixedly connected with the bottom of the bearing plate 82, a plurality of connecting rods 83 are uniformly fixed at the top of the bearing plate 82, a plurality of circulation holes 71 are uniformly formed in the inner bottom of the storage tank 7, the end parts of the plurality of connecting rods 83 respectively penetrate through the plurality of circulation holes 71, a fusiform block 84 is fixed at the end parts of the plurality of connecting rods 83, the maximum diameter of the fusiform block 84 is larger than the aperture of the circulation holes 71, the fusiform block 84 can smoothly move in the storage tank 7 filled with spore powder due to the sharp ends and the wide middle part, the annular baffle 72 is fixed at the periphery of the bottom of the storage tank 7, a gap is formed between the bottom of the annular baffle 72 and the top of the bearing plate 82, when the spore powder flows out from the lower part of the guide groove 91 and falls into the top of the bearing disc 82 from the plurality of circulation holes 71, as the spore powder content at the top of the bearing disc 82 is continuously accumulated, the pressure on the bearing disc 82 is continuously increased and moves downwards, and simultaneously the plurality of springs 821 are compressed to elastically deform, so as to store elastic potential energy, the bearing disc 82 moves downwards with the connecting rod 83, so that the fusiform block 84 moves downwards until the fusiform block 84 blocks the circulation hole 71, and the spore powder does not flow out from the circulation hole 71 any more, it is required to say that when the spore powder does not flow out from the circulation hole 71 any more, the spore powder content at the top of the bearing disc 82 is the largest amount that the classifying wheel 6 can handle without reducing the working performance, and for the sake of clarity, the classifying treatment amount of the classifying wheel 6 in the invention is 40kg/h model, that is, the average number of the classification of the spore powder per hour of the classification wheel 6 is 40kg, since the spore powder content falling to the top of the carrying disc 82 is 40kg, the classification wheel 6 can exert its maximum operation efficiency at this time to complete the total separation of 40kg of the spore powder within one hour, and at the same time, when the spore powder content at the top of the carrying disc 82 is reduced, the spring 821 releases elastic potential energy to drive the carrying disc 82 to move upward, so that the connecting rod 83 and the shuttle 84 move upward, thereby opening the flow hole 71 to let the spore powder flow out from the flow hole 71, so that the spore powder content at the top of the carrying disc 82 is in a constant state, and the closing and opening of the flow hole 71 will occur reciprocally during the operation of the air classification device, so that the spore powder content flowing from the top of the carrying disc 82 to the inner cavity of the classification drum 2 is at a constant value at the moment, so that the classification wheel 6 can effectively maintain a high-efficiency operation processing state.
It should be noted that, since a gap is formed between the bottom of the annular baffle 72 and the top of the carrier plate 82, when the airflow rotationally rises, the spore powder on the surface of the carrier plate 82 is sucked out of the gap under the action of the pressure difference and then rises along with the airflow.
Further, considering that spore powder can adhere to the wall of the classifying cylinder 2 in the process of rising along with the air flow, loss is easy to be caused when the spore powder is classified, in order to reduce the loss, the end parts of the connecting frames 21 are fixedly connected with the fixing pipes 10 together, the fixing pipes 10 are sleeved on the surface of the main shaft 8, cleaning components are arranged on the surfaces of the fixing pipes 10, the wall of the classifying cylinder 2 is ensured not to adhere to the spore powder through the matching use of the cleaning components and the classifying cylinder 2, the loss of the spore powder in the classifying process is effectively reduced, the spore powder rising along with the air flow can be sufficiently classified by the classifying wheel 6, meanwhile, impurities separated from the spore powder can be prevented from being adhered to the wall of the classifying cylinder 2 in the falling process, the impurities can be sufficiently discharged from the discharge opening, the inside of the classifying cylinder 2 is ensured to be kept clean after the work of the air flow classifying device is finished, and the impurities adhered to the wall of the classifying cylinder 2 are prevented from affecting the next operation of the air flow classifying device.

Since most of the classifying wheels 6 in the air classifying device for spore powder are vertically arranged, the inner bottom of the classifying wheel 6 accumulates spore powder to increase the loss amount of the spore powder in consideration of the structure of the classifying wheel 6 in the prior art, in order to avoid the occurrence of the phenomenon, an annular panel 61 is fixed at the inner bottom of the classifying wheel 6, the other side of the panel 61 is rotationally connected with the side wall of the conical hopper 31, and sealing treatment is performed at the connection, the height of the panel 61 close to the conical hopper 31 is higher than the height close to the periphery of the classifying wheel 6, a plurality of second scrapers 33 are fixed at the side wall of the conical hopper 31, the bottom of the second scrapers 33 is propped against the top of the panel 61, and in operation, the separated spore powder enters the center of the classifying wheel 6 and drives the panel 61 to rotate along with the classifying wheel 6, so that the spore powder falling on the surface of the panel 61 can be scraped by the second scrapers 33, thereby avoiding the occurrence of the accumulation phenomenon and being beneficial to reduce the loss of the spore powder.
The discharge port is fixedly connected with a discharge pipe 34, a screen 35 is fixed at the joint between the discharge pipe 34 and the discharge port, the aperture of the screen 35 is smaller than the particle size of spore powder, the top of the screen 35 and the top of the discharge port are obtuse angles, the pipe wall of the discharge pipe 34 is provided with a discharge port, the discharge port is positioned below the screen 35, when separated spore powder is discharged from the discharge port of the feeding barrel 3 into the discharge pipe 34, impurities smaller than the particle size of the spore powder in the spore powder are filtered under the filtering action of the screen 35, so that the separation effect of the impurities in the spore powder is further improved, the separated spore powder is finally discharged from the discharge port, and the impurities are discharged along the discharge pipe 34.

when the spore powder flows out from the lower part of the guide groove 91 and falls into the top of the bearing disc 82 from the plurality of circulation holes 71, as the spore powder content at the top of the bearing disc 82 is continuously accumulated, the pressure born by the bearing disc 82 is continuously increased and moves downwards, meanwhile, the plurality of springs 821 are compressed to elastically deform and store elastic potential energy, at the moment, the bearing disc 82 moves downwards with the connecting rod 83, so that the fusiform block 84 moves downwards until the fusiform block 84 plugs the circulation hole 71, at the moment, the spore powder no longer flows out from the circulation hole 71, at the moment, the spore powder at the top of the bearing disc 82 rises along with the airflow, so that the pressure born by the bearing disc 82 is reduced, and the springs 821 release the elastic potential energy to drive the bearing disc 82 to move upwards, so that the connecting rod 83 and the fusiform block 84 move upwards, so that the circulation hole 71 is opened, so that the spore powder flows out from the circulation hole 71, the spore powder content at the top of the bearing disc 82 is continuously at a constant value, and finally the spore powder content in the classification cavity in the classification cylinder 2 from the top of the bearing disc 82 is always at a constant value, so that the efficient operation state of the classification wheel 6 can be maintained.
