Detailed Description
The specific embodiments illustrated below are intended as descriptions of various configurations of the subject technology and are not intended to represent the only configurations in which the subject technology may be practiced. Specific embodiments include specific details for the purpose of providing a thorough understanding of the subject technology. It will be apparent, however, to one skilled in the art that the subject technology is not limited to the specific details shown herein and may be practiced without these specific details.
Typically, a gas extraction duct is provided at each station of the pharmaceutical plant for supplying the exhaust gas generated at that station to the corresponding gas treatment system. Specifically, the gas treatment system generally includes a gas extraction device, which extracts the exhaust gas generated at the station through a pipeline and then discharges the exhaust gas into the gas treatment system, and the exhaust gas generated by the operation is correspondingly treated by the gas treatment system.
In practice, since the exhaust gas generated at each station of the pharmaceutical workshop may contain a large amount of dust/dirt, the gas is taken directly through the pipeline, and the dust/dirt is easy to accumulate in the pipeline, especially at the bent part of the pipeline, due to the turbulent effect of the air flow, the dust/dirt is easy to accumulate. Therefore, the gas should be filtered to prevent the pipe from being clogged before entering the pipe.
Referring to fig. 1, fig. 2, fig. 3, fig. 4, a gas taking device for use in a pharmaceutical workshop for take out gas from the local space of the pharmaceutical workshop, including casing 1, casing 1 forms to get gas passageway 2, casing 1 is provided with to connect dirt box 3, it includes the opening to get gas passageway 2, the opening is located connect dirt box 3 directly over the direction, it is provided with filter screen 4 to get gas passageway 2, filter screen 4 slope set up in getting in gas passageway 2, filter screen 4 to connect dirt box 3 to be orthographic projection, filter screen 4 is in connect the projection on the dirt box 3 to be located completely connect in the dirt box 3 get gas passageway 2 in still be provided with rapping device 5, rapping device 5 raps filter screen 4, makes the dust that gathers on filter screen 4 fall into connect dirt box 3, rapping device 5 includes pivot 6, be provided with blade 7 in the pivot 6, the rotating shaft 6 is rotatably connected into the gas taking channel 2, the rotating shaft 6 is further provided with a vibrating head 8, the airflow in the gas taking channel 2 is driven by the blade 7 to rotate the rotating shaft 6, so that the vibrating head 8 intermittently vibrates the filter screen 4.
The housing 1 is usually made of plastic material, and in practical application, the material for making the housing 1 can be freely selected, however, it is preferable to use a chemically stable material for the housing 1 to avoid the chemical reaction between the housing 1 and the gas.
The filter screen 4 may be a filter screen 4 conventional in the art.
In the practical application process, the gas taking device for the pharmaceutical workshop is arranged at the corresponding station so as to collect the gas generated by the station, and the gas taking device for the pharmaceutical workshop is connected with the gas extractor of the gas treatment system through a pipeline. The piping should be connected to the gas handling system, whereby the gas at that station is taken out, then processed by the corresponding gas handling system, and finally discharged to the target location or atmosphere.
During the gas extraction process, a gas flow is formed in the gas extraction passage 2 under the action of the air extractor, and the gas flow is the waste gas generated by the corresponding station. When the air current flows in the air taking channel 2, acting force is applied to the blade 7, the rotating shaft 6 is driven to rotate under the action of the blade 7, and then the rotating shaft 6 drives the vibrating head 8 to rotate in the rotating process, so that the function of vibrating the filtering net 4 by the vibrating head 8 is realized. When the vibration head 8 vibrates the filter screen 4, dust is not easy to accumulate on the filter screen 4 due to the vibration of the filter screen 4, so that the filter screen 4 has stable air permeability. Furthermore, the pipeline is not easy to be blocked, and the stability of the gas treatment system is improved.
When the vibration head 8 vibrates the filter screen 4, the dust/dirt attached to the filter screen 4 is loosened or misplaced, so that the filter holes of the filter screen 4 can be prevented from being blocked. When the dust/dust does not have the bonding characteristic, the vibrator 5 can only vibrate the filter screen 4 to ensure that the filter holes of the filter screen 4 are kept smooth, and the dust/dust on the filter screen 4 can not enter the dust collection box at the moment due to certain acting force of air flow.
When the dust/dust has a bonding characteristic, that is, the volume of the dust/dust accumulated on the filter screen 4 increases with the increase of the accumulation amount, the rapping device 5 can shake off the dust/dust with the increased volume, and since the volume of the dust/dust has increased, the dust/dust with the increased volume cannot be sucked by the airflow, and the dust/dust with the increased volume enters the dust receiving box 3 under the action of gravity.
In some embodiments, a sponge block 9 is disposed in the dust collecting box 3, a part of the sponge block 9 extends to the air intake passage 2, the sponge block 9 in the air intake passage 2 closes the air intake passage 2, and the air flow in the air intake passage 2 passes through the sponge block 9 in the air intake passage 2.
The dust receiving box 3 is provided with a liquid supply pool 10 for supplying liquid to the sponge block 9, the liquid supply pool 10 is communicated with the sponge block 9 so as to supply the liquid to the sponge block 9, and dripping paper 11 for dripping the liquid in the liquid supply pool 10 into the sponge block 9 is arranged between the liquid supply pool 10 and the sponge block 9.
In practice, the sponge block 9 has air-permeable properties, and the sponge block 9 also has a certain adsorption capacity. For example, when a dust-containing air stream passes through the sponge block 9, a part of the dust adheres to the sponge block 9, and therefore, the sponge block 9 has a certain filtering property. In the pharmaceutical workshop, dust stagnant in the sponge block 9 may have a flying capability after the airflow containing dust/dirt is adsorbed by the sponge block 9, and therefore, the sponge block 9 can be moistened to accumulate or integrate the dust/dirt in the sponge block 9 into large particles, so that the dust/dirt is prevented from flying.
The drip paper 11 refers to a paper for discharging liquid in a leakage state, such as the drip paper 11 for coffee, and the like. The proposal is mainly used for wetting the sponge block 9 but not excessively wetting, namely, for avoiding that the sponge is in a saturated state to cause liquid to enter the air intake channel 2.
The drip paper 11 may be replaced with a valve structure having intermittent feeding capability to keep the sponge block 9 wet.
In some embodiments, the vibration head 8 is fixed on the rotating shaft 6 through a spring 12, one end of the spring 12 is fixedly connected with the vibration head 8, the other end of the spring 12 is fixedly connected with the rotating shaft 6, each vibration head 8 is fixed on the rotating shaft 6 through an independent spring 12, and the length of each spring 12 is different, so that different vibration heads 8 have different vibration intensity on the filter screen 4.
One end of the spring 12 may be welded to the shaft 6, and the other end of the spring 12 may be welded to the rapping head 8. The spring 12 may be replaced by other structures having elastic deformation capability. Because the vibration head 8 and the filter screen 4 have certain interference, the vibration head 8 and the rotating shaft 6 are connected by adopting a structure with elastic deformation capability, so that the vibration head 8 can smoothly continue to move after vibrating the filter screen 4, and further the rotating shaft 6 can rotate in sequence.
The blades 7 and the rotating shaft 6 are of an integrated structure, the blades 7 are three-dimensional curved surfaces, two groups of blades 7 are arranged, and the two groups of blades 7 are symmetrically arranged relative to the midpoint of the rotating shaft 6. The axis of the rotating shaft 6 does not intersect with the axis of the gas taking channel 2.
The blade 7 is a three-dimensional curved surface, and the blade 7 is easy to rotate by the airflow, so that the vibrator 5 has stable performance. However, because the blades 7 are three-dimensional curved surfaces, the acting force applied by the airflow to the blades 7 is divided into two component forces, one component force can push the blades 7 to rotate, and the other component force is directed along the axial direction of the rotating shaft 6, so that the two groups of blades 7 are symmetrically arranged, and the component forces along the axial direction of the rotating shaft 6 are mutually offset.
The vibration head 8 is of a hollow structure, a balancing weight 13 is arranged in the vibration head 8, the balancing weight 13 is spherical, a buffer layer 14 is arranged in the vibration head 8, and the thickness of the buffer layer 14 is not less than 1 mm. The vibration striking head 8 is wrapped by a rubber layer 15, the thickness of the rubber layer 15 is smaller than 1mm, and a wear-resistant layer 16 is coated outside the rubber layer 15.
The buffer layer 14 and the rubber layer 15 are arranged to reduce the noise generated during the operation of the rapping device 5 so as to optimize the application performance of the gas-taking device for the pharmaceutical workshop. The material of the balancing weight 13 is not limited, and the balancing weight 13 can move in the rapping head 8, so that the rapping device 5 is prevented from being in a balanced state and being incapable of rotating, and the application performance of the gas taking device for the pharmaceutical workshop is optimized.
In some embodiments, a positioning ring 17 for positioning the filter screen 4 is disposed on the housing 1, the positioning ring 17 is disposed on the housing 1 through a thread, and an inner side surface of the positioning ring 17 is in a bell mouth shape for facilitating an air flow to enter the air intake channel 2.
The dust collecting box 3 is inserted into the casing 1, a through hole for air flow to pass through is arranged on the part of the dust collecting box 3 positioned in the air taking channel 2, and a supporting net 18 for supporting the sponge block 9 is arranged on the through hole.
