In this embodiment, the first feeding channel 4 and the second feeding channel 5 are used for connecting the first cylinder 1 and the second cylinder 2 with an abrasive hopper, respectively, the first feeding channel 4 and the second feeding channel 5 are communicated with the vacuum generating device 30, the first feeding channel 4 is provided with a first vacuum valve 41 for blocking the communication between the vacuum generating device 30 and the first cylinder 1 and a first sand inlet valve 42 for controlling the on-off of the first feeding channel 4, and the second feeding channel 5 is provided with a second vacuum valve 51 for blocking the communication between the vacuum generating device 30 and the second cylinder 2 and a second sand inlet valve 52 for controlling the on-off of the second feeding channel 5. Through the arrangement and the combination of the control system, when the material spraying process of the first cylinder 1 and the material filling process of the second cylinder 2 are performed, the control system controls the main air inlet pipe 33 to be communicated with the first air inlet pipe 31, and simultaneously controls the first vacuum valve 41 and the first sand inlet valve 42 to be closed, the second vacuum valve 51 and the second sand inlet valve 52 to be opened, at this time, the first cylinder 1 forms a closed cavity, and compressed air can extrude the abrasive material from the first discharge channel 6; the second cylinder 2 is acted by the vacuum generating device 30 to form negative pressure, and the grinding material enters the second cylinder 2. Similarly, when the two cylinders are used for exchanging the material spraying and filling processes, the control system controls the opening and closing of the vacuum valve and the sand inlet valve according to the current operation of the cylinders in the material spraying process or the material filling process.
Preferably, first cylinder 1 and second cylinder 2 still are equipped with discharge valve 11, the break-make of discharge valve 11 in this embodiment is the same to be controlled through control system, because the cylinder body is spouting the material flow after, still have partial compressed gas can't be discharged in the cylinder body, the pressure in the cylinder body is great this moment, when switching to the flow of packing, control system can open discharge valve 11 on the cylinder body earlier and make cylinder body and outside intercommunication, and open a period of time continuously, discharge compressed air through discharge valve 11 until the atmospheric pressure in the cylinder body is the same with atmospheric pressure, later close discharge valve 11, open the vacuum valve of cylinder body again and go into the sand valve and carry out the packing.
In this embodiment, the top of the first cylinder 1 and the top of the second cylinder 2 are both provided with an exhaust cover assembly, the exhaust cover assembly comprises a hollow channel, a lower exhaust cover and an upper exhaust cover, the hollow channel is arranged on the top of the cylinder and is communicated with the inside of the cylinder, and the cylinder penetrates through the hollow channel and extends inwards to form an exhaust hole with a cross section area smaller than that of the hollow channel in the hollow channel. The upper exhaust cover and the lower exhaust cover are both hollow hemispheres, the lower exhaust cover is arranged in the hollow channel and is positioned below the exhaust holes, the upper exhaust cover is arranged in the hollow channel and is positioned above the exhaust holes, and the upper exhaust cover and the lower exhaust cover penetrate through the exhaust holes through springs to realize connection of the upper exhaust cover and the lower exhaust cover. In a conventional state, the upper exhaust cover is pressed on the exhaust cover by the self weight, the cylinder body is not sealed at the moment, when the cylinder body starts to spray materials, the air compressor 20 introduces compressed air into the cylinder body, the lower exhaust cover is also extruded by the compressed air to move upwards along the hollow channel until the exhaust hole is blocked, and the cylinder body is sealed and forms a high-pressure environment at the moment, so that the abrasive materials can be discharged along the discharge channel; and when the abrasive in the cylinder body is sprayed soon and stops spraying the material and will be converted into the flow of filling, the control system firstly opens the exhaust valve 11, the compressed air in the cylinder body is emptied, at the moment, the lower exhaust cover falls down under the dead weight due to the reduction of the air pressure in the cylinder body, the air in the cylinder body can be discharged along with the hollow channel, and then the cylinder body can carry out the flow of filling. When the cylinder body carries out the flow of packing, the air in the cylinder body was discharged this moment, and last exhaust cover received the dead weight to press on the exhaust hole, and vacuum generating device 30 opens and takes away the air in the cylinder body and form the negative pressure, and last exhaust cover just can be tightly pushed down the exhaust hole under the effect of atmospheric pressure this moment, realizes the sealed and negative pressure state of cylinder body, ensures that the abrasive material can enter into the cylinder body along charge-in channel.
In this embodiment, the first discharging channel 6 and the second discharging channel 7 are both communicated with the respective cylinder body and are arranged at the bottom of the respective cylinder body, and the abrasive can fall to the bottom of the cylinder body under the self weight of the abrasive and smoothly enter the corresponding discharging channel below the abrasive. First discharging channel 6 is equipped with and is used for controlling first discharging channel 6 break-make's first sand valve 61, second discharging channel 7 is equipped with and is used for controlling second sand valve 71 of second discharging channel 7 break-make, through the aforesaid setting, combines foretell control system, and when the corresponding cylinder body carries out the sandblast flow, the sand valve in this cylinder body of control system control is opened, and the abrasive material can get into discharging channel through the sand valve. When the corresponding cylinder body is subjected to a filling process, the control system controls the sand outlet valve in the cylinder body to be closed, at the moment, the cylinder body forms a closed cavity, and abrasive materials can enter the cylinder body through the feeding channel.
Because the abrasive grains are small, the abrasive grains have high friction force, and even under the extrusion action of compressed air, the abrasive grains cannot uniformly move in the discharge channel. To this, all be equipped with the screw conveyor 62 that is used for pushing out the abrasive material in first discharging channel 6 and the second discharging channel 7 in this embodiment, can evenly will fall into discharging channel's abrasive material through screw conveyor 62 and impel forward, make the even blowout of abrasive material, avoid appearing the condition that the interval spouts the material, the working effect is better.
At the same time, the first and second flow channels 6, 7 merge to form a main pipe 72, which main pipe 72 is used for connecting to the sand blasting lance 40. Through this setting, join the discharging channel of two cylinder bodies, directly connect through a sand blasting gun 40 and just can realize the sandblast to the work piece, saved the cost (all set up sand blasting gun 40 with two discharging channel) and also improved work efficiency simultaneously (need not change discharging channel's sand blasting gun 40 when two cylinder bodies spout the material flow in turn).
Preferably, the main air inlet pipe 33 is connected with the main discharge pipe 72 through a sand discharge pipe, and the sand discharge pipe is provided with a sand discharge valve 73 for controlling the on-off of the sand discharge pipe. Since a part of the abrasive remains in the main tapping pipe 72 after the completion of the blasting operation of the workpiece, the recovery of the apparatus is not facilitated. In contrast, after the sand blasting operation is finished, the sand discharge valve 73 can be controlled to be opened, the main inlet pipe 33 is communicated with the main outlet pipe 72, and the compressed gas can spray the abrasive in the main outlet pipe 72 from the sand blasting gun 40, so as to ensure that the abrasive is not accumulated in the main outlet pipe 72.
In this embodiment, the first sand inlet valve 42, the second sand inlet valve 52, the first sand outlet valve 61, the second sand outlet valve 71 and the sand discharge valve 73 are all V-shaped ball valves, the V-shaped ball valves belong to fixed ball valves and are also single-seat sealing ball valves, the adjusting performance is the best of the ball valves, the flow characteristics are equal percentage, and the adjustable ratio reaches 100: 1. The V-shaped notch and the metal valve seat have a shearing effect, and are particularly suitable for media containing fibers, tiny solid particles, slurry and the like. The scheme is realized by opening and closing a pneumatic control valve. In this embodiment, two cylinders perform different processes simultaneously, that is, when one type of valve (sand inlet valve, vacuum valve, and sand outlet valve) in one cylinder is opened, the other cylinder will close the same type of valve, for example: when the first cylinder 1 is in the sand blasting process, the first sand outlet valve 61 is opened, and when the second cylinder 2 is in the filling process, the second sand outlet valve 71 is closed. Therefore, in the embodiment, besides the control system, the opening and closing of the same type of switches of the two cylinders can be controlled through linkage control of a mechanical structure.
According to the scheme, whether the switching of the two cylinder body processes is executed or not is judged according to the stock of the abrasive materials in the cylinder body, the cylinder body is usually kept in a sealed state in the working process, and workers cannot visually know the stock of the abrasive materials in the cylinder body. In this regard, in the present embodiment, detectors for detecting the height of the abrasive deposited in the cylinder are provided in both the first cylinder 1 and the second cylinder 2, and the detectors include a lower limit detector 82 provided at the bottom of the cylinder and an upper limit detector 81 provided at the upper part of the cylinder. The lower limit detector 82 is used for detecting that the corresponding cylinder body sprays the material, and if the abrasive material consumption in the cylinder body reaches the height position of the lower limit detector 82, the material spraying flow of the cylinder body is stopped at the moment, the cylinder body is converted into a filling flow, and the cylinder body is switched to another cylinder body for spraying the material; the same upper limit detector 81 is used to detect that the corresponding cylinder body is filling, and if the abrasive material accumulation in the cylinder reaches the height position of the upper limit detector 81, the filling process of the cylinder body is stopped at this time, and the next switching of the material spraying process is waited (normally, the filling speed of the filling process is greater than the material spraying speed, and the alternate circulation of the two cylinder bodies can be satisfied).
Preferably, the lower limit detector 82 and the upper limit detector 81 are both rotation-stopping level switches. The rotation-resisting material level switch uses a micro motor as a driving device, a transmission shaft is connected with a clutch, when the motor does not contact with the material, the motor operates normally, and when blades contact with the material, the motor stops rotating. By the principle, the condition that the output contact point signal of the lower limit detector 82 is set to be that the abrasive does not block the blade, the motor can start to operate, and at the moment, the material spraying flow of the cylinder is stopped; the upper limit detector 81 outputs a contact signal when the abrasive material blocks the blade and the motor stops rotating, thereby stopping the filling process of the cylinder.
Similarly, since the abrasive particles themselves are small and have a large friction force with each other, the abrasive particles cannot uniformly fall into the discharge passage from the cylinder even under the squeezing action of the compressed air. To this end, all still be equipped with in first cylinder body 1 and the second cylinder body 2 and make things convenient for the inside abrasive material of cylinder body to get into discharge channel's agitating unit 9 separately, agitating unit 9 includes pivot, a plurality of puddler and a plurality of chain, and a plurality of puddlers set firmly in the pivot and follow the circumference interval distribution of pivot, the one end of chain set firmly in on the free end of puddler, the other end set firmly in the pivot and lie in the puddler below. Through the continuous rotation of chain and puddler, the abrasive material in the even stirring cylinder body makes the abrasive material in the cylinder body can be faster more even fall into discharging channel, combines compressed gas's extrusion, can ensure to spout the even smooth and easy of the ejection of compact of material flow.
Preferably, a hopper 91 for preventing the abrasive in the cylinder from accumulating and pressing the stirring device 9 is further disposed in each of the first cylinder 1 and the second cylinder 2, and the hopper 91 is nested in the respective cylinder and is located between the feeding channel of the respective cylinder and the stirring device 9. Because the abrasive material quantity in the cylinder body is too much and the quality is heavier, can roughly divide into two parts through this funnel 91 structure with the cylinder body, the abrasive material in the half can receive the support of funnel 91 in the top simultaneously, can not all extrude on agitating unit 9, the big one end of funnel 91 opening is up simultaneously, the little one end of opening is down, can make the abrasive material of upper portion flow to the below comparatively slowly, ensures that agitating unit 9 can not receive too big resistance, and normal operating ensures that the abrasive material can not overstock cylinder body bottom.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
