Abstract

This invention discloses a veterinary drug concentrate refining filter, relating to the field of steam filter technology. It includes a lower shell with an upper shell mounted on it. The upper shell is used to filter impurities from the steam during veterinary drug concentrate refining. A receiving and limiting component is installed at the bottom of the upper shell, limiting the lower shell. A maintenance control component is installed on the lower shell, detecting the disassembly of the lower shell. The invention utilizes air pressure compensation pipes to promote the discharge of moisture adhering to the filter cartridge and filter cloth, reducing the moisture content of the filter cartridge and filter cloth, and lowering the risk of contamination during subsequent disassembly and replacement of the filter cartridge. This addresses the problem that current veterinary drug concentrate refining filters are inconvenient for compensating air pressure and pre-discharging residual impurities and droplets within the filter cartridge, increasing the risk of diffusion and contamination during filter cartridge disassembly.

Description

Technical Field

[0001] This invention relates to the field of steam filter technology, specifically to a filter for refining veterinary drug concentrate. Background Technology

[0002] In actual veterinary drug concentrate refining, concentration and other processes are required. Especially in refining processes involving powdered raw materials such as traditional Chinese medicine, exhaust gas needs to be filtered to remove impurities and prevent contamination from medicinal materials and diffused liquids in the steam. Steam filters are typically used for this purpose. However, current veterinary drug concentrate refining filters lack a confining lower shell to catch dripping liquid during filter element replacement, easily causing filtered droplets containing impurities to contaminate the ground or pipelines, posing a safety hazard. Furthermore, automatic gas path closure is not convenient during filter element replacement. If the gas path is not closed in advance, splashing during filter removal can lead to the accidental inhalation or skin contact with impurities and diffused exhaust gases. Additionally, it is difficult to compensate for gas pressure and pre-vent residual impurities and droplets within the filter element, further increasing the risk of contamination during filter element removal.

[0003] Therefore, we propose a veterinary drug concentrate refining filter. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention employs a receiving and limiting component to limit the lower shell. After the lower shell is disassembled, it can be kept directly below the filter element shell, maintaining the stability of the lower shell and preventing it from being left unstabilized after disassembly. If the lower shell tipps over, internal impurities and droplets can easily leak out. By using the lower shell to receive the filter element shell from below, any small amount of residual droplets on the filter element shell can drip directly onto the lower shell during disassembly, facilitating quick and easy packaging of the filter element shell for safe disassembly.

[0017] The maintenance control components automatically detect the disassembly and loosening of fastening bolts. Automatic detection occurs whenever any fastening bolt begins to be disassembled, and the system automatically controls the closure of the intake solenoid valve during bolt removal. This accurate structural detection increases operator compliance and prevents workers from forgetting to close the intake solenoid valve. The discharge control components facilitate daily condensate drainage, preventing issues caused by inadequate condensation equipment in upstream processes or changes in ambient temperature. Combined with a pressure compensation component, the system automatically controls positive pressure jetting during bolt disassembly to pre-discharge accumulated condensate droplets inside the lower housing and uses pressure from the compensation pipe to promote the removal of moisture adhering to the filter cartridge and filter cloth, reducing their moisture content and minimizing the risk of contamination during subsequent lower housing disassembly and filter cartridge replacement.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1 to 9 As shown:

[0030] This invention provides a technical solution: a veterinary drug raw material refining filter, comprising a lower shell 1, an upper shell 2 mounted on the lower shell 1, the upper shell 2 being used to filter steam impurities during the refining of veterinary drug raw material; a receiving and limiting component 3 mounted at the bottom of the upper shell 2; the receiving and limiting component 3 being used to limit the lower shell 1; a maintenance control component 4 mounted on the lower shell 1; the maintenance control component 4 being used to detect the disassembly of the lower shell 1; a pressure compensation component 5 mounted on the upper shell 2; a discharge control component 6 mounted at the bottom of the lower shell 1; the discharge control component 6 being used to discharge impurities; the lower shell 1 includes: a lower shell 101 and a spring ring 1011, the spring ring 1011 being fixedly sleeved on the lower shell 101; and a flange provided on the lower shell 101.

[0031] The lower shell 1 includes: fastening bolts 102 and a limiting ring 103. A ring of fastening bolts 102 is inserted into the flange on the lower shell 101. The limiting ring 103 is fixedly installed inside the lower shell 101. A groove is formed on the limiting ring 103. The upper shell 2 includes: an upper shell 201, a vent plate 2011, a filter element shell 202, and a filter cloth 203. A flange is provided at the bottom of the upper shell 201. A ring of threaded holes is provided on the flange on the upper shell 201. A ring of fastening bolts 102 are threadedly connected to the upper shell 201. The upper shell 201 fits tightly against the lower shell 101. A vent plate 2011 is fixedly installed at the bottom of the upper shell 201. A ring of through holes is provided on the vent plate 2011. A filter element shell 202 is threadedly connected to the bottom of the air plate 2011; a through groove is provided on the filter element shell 202; activated carbon particles are filled inside the filter element shell 202; a filter cloth 203 is fixedly sleeved on the outside of the filter element shell 202; the filter cloth 203 is used to filter impurities in the steam of veterinary drug raw material refining; the receiving limiting component 3 includes: a sleeve ring 301, a sliding post 302, and a rubber anti-slip ring 303. The sleeve ring 301 is fixedly installed at the bottom of the air plate 2011; a rubber layer is provided on the outside of the sleeve ring 301, and the rubber ring on the outside of the sleeve ring 301 is sleeved inside the lower shell 101; a ring of sliding posts 302 is fixedly installed on the sleeve ring 301 by bolts, and each ring of sliding posts 302 slides and fits into the air plate 2011. Inside the groove on the inner side of the limiting ring 103, a rubber anti-slip ring 303 is fixedly sleeved at the bottom of a ring of sliding columns 302. The outer sides of the rubber anti-slip rings 303 slide against the inner wall of the lower shell 101, and each rubber anti-slip ring 303 protrudes from the groove on the inner side of the limiting ring 103. The lower shell 101 is limited by the receiving limiting component 3. After disassembling the lower shell 101, it remains directly below the filter element shell 202, maintaining its stability and preventing it from becoming unstable after disassembly. If the lower shell 101 tilts, internal impurities and droplets can easily leak out. The lower shell 101's position under the filter element shell 202 is thus protected. Fang Chengjie can ensure that when disassembling the filter element shell 202, a small amount of residual liquid droplets on the filter element shell 202 can be directly dripped onto the lower shell 101, making it easy to quickly pack the filter element shell 202 with a packaging bag for safe disassembly. The flange on the air inlet pipe 206 is bolted to the exhaust pipe of the veterinary drug concentration and evaporation equipment, and the flange on the exhaust pipe 207 is bolted to the exhaust gas discharge pipe to the outside. As air enters through the air inlet pipe 206, it passes through the ventilation plate 2011, filters impurities through the filter cloth 203, and adsorbs odors through the activated carbon particles inside the filter element shell 202, and is discharged from the exhaust pipe 207. The valve on the slag discharge pipe 601 can be opened periodically to discharge accumulated water.After the fastening bolts 102 are removed, the lower shell 101 can fall under its own weight. With the help of the limiting rings 103 set by the four sliding pillars 302, the lower shell 101 can only move vertically downwards until the limiting rings 103 fall above the rubber anti-slip rings 303 and are stopped. The friction of the rubber anti-slip rings 303 against the lower shell 101 reduces the falling speed and makes the fall more stable.

[0032] The upper housing 2 further includes: a plug-in post 204, a time delay switch 205, and a micro switch 2051. Two plug-in posts 204 are fixedly installed at the bottom of the upper housing 201; the two plug-in posts 204 pass through the flanges on the lower housing 101 respectively; the time delay switch 205 is fixedly installed at the bottom of the plug-in post 204 on the same side, and the micro switch 2051 is fixedly installed at the bottom of the plug-in post 204 on the same side; the upper housing 2 also includes: an intake pipe 206, an intake solenoid valve 2061, an exhaust pipe 207, and an exhaust solenoid valve 2071. The intake pipe 206 is fixedly installed on the upper housing 201; the intake pipe 206 is equipped with... A flange; an intake solenoid valve 2061 is installed on the intake pipe 206; an exhaust pipe 207 is fixedly installed on the upper shell 201, and the end of the exhaust pipe 207 is fixedly installed on the vent plate 2011; an exhaust solenoid valve 2071 is fixedly installed on the exhaust pipe 207; a micro switch 2051 is electrically connected to the intake solenoid valve 2061; the maintenance control component 4 includes: a detection sleeve 401, which is slidably sleeved on the lower shell 101; the maintenance control component 4 also includes: a support spring 402, which is sleeved on the lower shell 101; one end of the support spring 402 is fixedly connected to the spring coil 1. On 011, the other end of the support spring 402 is fixedly connected to the bottom of the detection sleeve 401; a ring of fastening bolts 102, a time delay switch 205, and a micro switch 2051 are pressed and fitted on the top of the detection sleeve 401. The maintenance control component 4 can automatically monitor the disassembly operation of the fastening bolts 102. At the same time, it can automatically detect when any fastening bolt 102 begins to be disassembled. It can automatically control the closing of the intake solenoid valve 2061 when the fastening bolt 102 is disassembled. The structure detection is accurate, which can increase the standardization of operation by the staff and also prevent the staff from forgetting to close the intake solenoid valve 206. 1. Automatic control of the gas path can block the leakage of drug-containing exhaust gas, preventing operators from being poisoned or burned by contact with high-temperature liquid drugs or inhalation of toxic gases; at the same time, it can prevent batch cross-contamination and secondary environmental pollution caused by the diffusion of drug components, making the structure safer; when the fastening bolt 102 is removed, as the fastening bolt 102 is unscrewed, the detection sleeve 401 can be squeezed to move down and compress the support spring 402. At this time, the detection sleeve 401 no longer squeezes the delay switch 205 and the micro switch 2051. At this time, the micro switch 2051 can automatically control the intake solenoid valve 2061 to close, thereby stopping the intake of air.

[0033] In Example 2, based on Example 1, the pressure compensation component 5 includes: a pressure compensation pipe 501 and a compensation solenoid valve 5011. The pressure compensation pipe 501 is fixedly installed on the upper shell 201; the pressure compensation pipe 501 is fixedly inserted into the exhaust pipe 207; the compensation solenoid valve 5011 is fixedly installed on the pressure compensation pipe 501; the pressure compensation pipe 501 connects to the filter element shell 202; the emission control component 6 includes: a slag discharge pipe 601, a slag discharge solenoid valve 6011, and a branch pipe 602. The slag discharge pipe 601 is fixedly installed at the bottom of the lower shell 101; the slag discharge solenoid valve 6011 is fixedly installed on the slag discharge pipe 601; the branch pipe 602 is fixedly installed on the slag discharge pipe 601, and the branch pipe 602 is equipped with a valve. The slag discharge pipe 601 and the branch pipe 602 are respectively connected to a storage container through a flexible hose; the time delay switch 205 is electrically connected to the exhaust solenoid valve 2071, the compensation solenoid valve 5011, and the slag discharge solenoid valve 2071. Valve 6011, with discharge control component 6, facilitates daily condensate drainage for staff, preventing condensate from failing to drain in time due to inadequate condensation equipment in upstream processes or changes in ambient temperature. Simultaneously, in conjunction with pressure compensation component 5, it automatically controls positive pressure jetting when staff operate to disassemble and tighten bolts 102, pre-draining accumulated condensate droplets inside the lower housing 101 and using air pressure to promote the drainage of moisture adhering to the filter element housing 202 and filter cloth 203, reducing the moisture content of the filter element housing 202 and filter cloth 203, thus reducing the risk of contamination during subsequent disassembly of the lower housing 101 and replacement of the filter element housing 202. The method of emptying the lower housing 101 further reduces the risk of contamination, preventing a large amount of residual impurities and vapor from dispersing in the air after disassembly. The control is simple and direct, and the delayed control method does not affect subsequent normal maintenance work.

[0034] The working principle of this embodiment is as follows: First, the flange on the air inlet pipe 206 is bolted to the exhaust pipe of the veterinary drug concentration and evaporation equipment. The flange on the exhaust pipe 207 is bolted to the exhaust pipe leading outdoors. As air enters through the air inlet pipe 206, it passes through the ventilation plate 2011, filters impurities through the filter cloth 203, and adsorbs odors through the activated carbon particles inside the filter element shell 202. The air is then discharged from the exhaust pipe 207. The valve on the slag discharge pipe 601 can be opened periodically to drain accumulated water. When the filter element shell 202 needs to be disassembled for replacement after long-term use, it can be disassembled by turning the fastening bolt 102 one turn with a wrench. When the fastening bolt 102 is unscrewed, the detection sleeve 401 is squeezed downwards, compressing the support spring 402. At this time, the detection sleeve 401 no longer presses the delay switch 205 and the micro switch 2051. When the micro switch 2051 is pressed, it can automatically control the intake solenoid valve 2061 to close, thus stopping the intake of air. When the delay switch 205 is not pressed, it can control the exhaust solenoid valve 2071 to close and control the compensation solenoid valve 5011 and the slag discharge solenoid valve 6011 to open. At this time, the air pump connected to the air pressure compensation pipe 501 supplies air, which is discharged from the inside of the filter element shell 202 to the outside, promoting the discharge of liquid droplets attached to the filter element shell 202 and the filter cloth 203. At the same time, if there is water in the lower shell 101, it can be discharged directly from the slag discharge pipe 601 under the action of air pressure, which can ensure that the lower shell 101 is emptied. At the same time, the delay switch 205 can control the exhaust solenoid valve 2071 to open and control the compensation solenoid valve 5011 and the slag discharge solenoid valve 6011 to close. Because it takes time to remove one ring of fastening bolts 102, the emptying work can be completed before one ring of fastening bolts 102 is completely removed.

[0035] After the fastening bolts 102 are removed, the lower shell 101 falls under its own weight. The limiting ring 103, in conjunction with the four sliding pins 302, limits the movement of the lower shell 101, ensuring that it can only move vertically downwards. The lower shell 101 falls until it is stuck above the rubber anti-slip ring 303. The friction of the rubber anti-slip ring 303 against the lower shell 101 reduces its falling speed. After the lower shell 101 falls, the filter element shell 202 can be manually rotated and removed. During the process, a small amount of liquid dripping from the filter element shell 202 can be caught by the lower shell 101. After removing the filter element shell 202, simply wrap it in a packaging bag and pull it out from the lower shell 101 to reduce the risk of contamination.
