Abstract
Description
Technical Field
[0001] This application belongs to the field of water pollution control agents technology, specifically relating to a non-powered automatic dosing device for water pollution control agents. Background Technology
[0002] In the process of water pollution treatment, filter powders such as carbon powder are usually mixed with water to form a solution, which is then transported into the filter cartridge to adsorb oil, organic impurities, odors and color substances in the water. An auxiliary filter layer is formed on the surface of the filter disc to improve the interception effect of fine suspended solids and colloidal impurities.
[0003] The dosing of existing water pollution control agents usually relies on manual operation or adjustment through motors, liquid level sensors and controllers. This results in problems such as inaccurate dosage, high equipment costs and energy consumption. At the same time, the filter powder is hygroscopic and has the property of accumulating. It is easy to get damp, adhere, clump or form bridges in the dosing chamber and dosing channel, causing poor dosing and unstable dosage.
[0004] In addition, existing liquid level-linked dosing structures may be reversed when the liquid level drops, resulting in repeated dosing. Therefore, there is an urgent need for a dosing device for water pollution control agents that can automatically control the powder dispensing by utilizing liquid level changes, requires no external power, and has the functions of closed quantitative dosing, auxiliary dosing, and uniform powder mixing.
[0005] Application content
[0006] To address the problems mentioned in the background technology, a dosing process is formed by triggering buoyancy sensing based on changes in the liquid level in the storage tank, driving the quantitative dosing roller assembly in one direction, and conveying the filtered powder in a closed, quantitative manner. Simultaneously, the rotation and dispersion of the buoyancy roller assembly and the vibration action of the auxiliary dosing arm assembly are controlled. This process integrates liquid level sensing, non-powered drive, closed quantitative dosing, auxiliary dosing, and powder dispersion and mixing. This reduces the external power and electrical control requirements while improving the compatibility between the amount of filtered powder and the amount of hydrolysate, the continuity of dosing, and the uniformity of mixing.
[0007] To achieve the above objectives, this application provides the following technical solution: a non-powered automatic dosing device for water pollution control agents, comprising a frame assembly, and further comprising:
[0008] A dosing chamber assembly is disposed at one end inside the frame assembly. The dosing chamber assembly includes a top chamber for storing filter powder, an inclined chamber for dispensing the powder at the bottom of the top chamber, a dosing circular chamber for sealed dosing fixedly disposed at the bottom of the inclined chamber, and a storage chamber for dissolving the filter powder fixedly disposed at the bottom of the dosing circular chamber.
[0009] An auxiliary drug dispensing arm assembly is disposed on the outside of the inclined chamber and is used to provide vibration-assisted drug dispensing to the filtered drug powder on the inner wall of the inclined chamber.
[0010] A metering dosing roller assembly is rotatably mounted inside a dosing chamber. By rotating the metering dosing roller assembly inside the dosing chamber, the filtered powder in the top chamber is rotated and meteredly delivered to the storage chamber in a closed state.
[0011] A buoyancy roller assembly is floatingly disposed within a liquid storage tank. As the liquid stored in the liquid storage tank rises and falls, the buoyancy roller assembly floats and rises and falls within the liquid storage tank.
[0012] A single-stroke drive wheel assembly is disposed at one end of the metering dosing roller assembly, and one side of the single-stroke drive wheel assembly meshes with the buoyancy roller assembly. When the buoyancy roller assembly rises and floats, the single-stroke drive wheel assembly converts the rising and floating of the buoyancy roller assembly into the self-rotation dosing of the metering dosing roller assembly and the self-rotation vibration of the auxiliary dosing arm assembly. This utilizes the change in liquid level in the storage tank as the dosing trigger and driving condition, and links the metering dosing, vibration dosing, and powder mixing actions to achieve adaptive dosing control without the need for external power.
[0013] Preferably, the frame assembly includes a processing frame, and a pump and a filter cartridge are disposed at the end of the processing frame away from the dosing chamber assembly;
[0014] The dosing chamber assembly also includes an end protection chamber, which is fixed to one end of the top chamber and the storage chamber. A traveling gear arm is fixedly installed at the bottom of the end protection chamber. An L-shaped end frame and a bellows are installed on the outer side of the storage chamber near the end protection chamber. A T-shaped frame is fixedly installed inside the L-shaped end frame. Auxiliary gears are rotatably installed at both ends of the outer side of the T-shaped frame, and a traveling gear ring is fixedly installed at the center of the inner side of the T-shaped frame. Through-hole circular grooves are opened on both sides of the end protection chamber near the top chamber. An infusion pipe is installed on the outer side of the storage chamber away from the end protection chamber, and an infusion valve is installed on the infusion pipe. A side wing frame is fixedly installed on the outer side of the inclined chamber, and a wing frame slide groove is opened on the side wing frame. Guide slide rods are fixedly installed at both ends inside the storage chamber. This forms a filtration, drug storage, drug dissolution, and infusion space within the same processing frame, and provides an installation, protection, and motion guidance foundation for floating and rotary transmissions through the end protection chamber, support frame, and guide structure.
[0015] Preferably, the buoyancy roller assembly includes a second shaft and a first shaft. A second gear and a second floating roller are fixedly mounted on the second shaft, and a first gear and a first floating roller are fixedly mounted on the first shaft. The first and second floating rollers are provided with convex roller heads. One end of the second shaft and one end of the first shaft are respectively rotatably mounted on the floating roller end platform. A floating roller tooth arm is fixedly mounted on one side of the top of the floating roller end platform. The rods at both ends of the second shaft and the first shaft are respectively rotatably mounted on the support end platform through bearings. An end platform groove is provided on the support end platform.
[0016] The second and first floating rollers are installed inside the liquid storage tank. The support end platform slides on the guide slide rod through the end platform slide groove. The second shaft is rotatably mounted on the bellows through the bearing. The second gear and the first gear are installed outside the liquid storage tank. The second gear meshes with the traveling gear arm. The second gear meshes with the first gear so that the buoyancy roller assembly can rise and fall stably with the liquid level. During the rising and falling process, the gear meshing makes the first and second floating rollers rotate synchronously in opposite directions, thereby taking into account the functions of liquid level sensing, powder receiving and dispersion, and hydrolysis liquid agitation.
[0017] Preferably, the auxiliary drug delivery arm assembly includes an arm shaft, with an arm gear and a crankshaft fixedly mounted at both ends of the arm shaft, and a plurality of first traction arms rotatably mounted on the crankshaft via bearings. A second traction arm is rotatably mounted at the end of the first traction arm away from the crankshaft via bearings, and a rubber hammer is fixedly mounted at the end of the second traction arm away from the first traction arm.
[0018] The arm shaft is rotatably mounted at the end of the T-shaped frame via bearings. The arm gear meshes with the auxiliary gear. The second traction arm slides through the wing frame groove on the side wing frame. The rubber hammer faces the outside of the inclined chamber. The crankshaft rotates within the through circular groove. This converts the rotational motion of the arm shaft into a reciprocating vibration motion of the rubber hammer along the wing frame groove, periodically striking the outer wall of the inclined chamber to reduce the adhesion, clumping, and bridging of filter powder.
[0019] Preferably, the metering dosing roller assembly includes a rotating shaft, on which a dosing roller is fixedly mounted. The edge of the dosing roller has multiple dosing grooves. A stirring shaft is rotatably mounted in the dosing grooves via bearings. A stirring blade is mounted on the stirring shaft and is located in the dosing grooves. A rotating gear is mounted at one end of the stirring shaft and is located on the outer side of one end of the dosing roller.
[0020] The dosing rollers at both ends are rotatably mounted on both ends of the dosing hopper via bearings. The rotating shaft is rotatably mounted on the T-shaped frame via bearings. The rotating gear is located outside the traveling gear ring and meshes with the outer side of the traveling gear ring. This allows for the fixed-volume reception and sealed transfer of filtered powder using the dosing tank. The meshing of the rotating gear with the traveling gear ring causes the stirring blades to rotate synchronously within the dosing tank, promoting the loose discharge of powder and improving the stability of the dosing amount.
[0021] Preferably, the single-drive wheel assembly includes a single-drive shaft and a drive housing frame. A single-drive gear and a single-drive ratchet are fixedly installed at both ends of the single-drive shaft. A housing frame gear ring is fixedly installed on the outer surface of the drive housing frame, and multiple pawls are rotatably installed on the inner side of the drive housing frame. A clamping spring is installed between the pawls and the inner side of the drive housing frame. The pawls abut against the single-drive ratchet by the clamping springs pushing against them.
[0022] The single-stroke shaft is rotatably mounted on the L-shaped end frame via bearings. The single-stroke gear is located on the outside of the L-shaped end frame, while the single-stroke ratchet and drive chamber frame are located on the inside of the L-shaped end frame. The drive chamber frame is fixedly mounted on the end of the rotating shaft, and the chamber frame gear ring meshes with the auxiliary gear. This allows for unidirectional power transmission through the single-stroke ratchet and pawl, enabling the buoyancy roller assembly to drive the dosing roller and auxiliary dosing structure when it floats. Conversely, when the buoyancy roller assembly falls back down, the reverse power is cut off to prevent further dosing during the liquid level drop.
[0023] Preferably, when the buoyancy roller assembly floats, the upward-moving float roller toothed arm drives the single-stroke shaft to rotate via a single-stroke gear, and the single-stroke shaft drives the drive chamber frame to rotate via a single-stroke ratchet and pawl; so as to convert the linear upward movement of the float roller toothed arm into the rotational movement of the drive chamber frame, providing the metering dosing roller assembly and the auxiliary dosing arm assembly with mechanical driving force triggered by the liquid level change.
[0024] Preferably, the floating roller toothed arm is located inside the end protection chamber and is located on one side of the single-pass gear. The floating roller toothed arm meshes with the single-pass gear. When the buoyancy roller assembly floats, the single-pass shaft drives the self-rotating shaft to rotate unidirectionally through the single-pass ratchet, pawl and drive chamber frame. This limits the power transmission only along the upward direction of the buoyancy roller assembly, keeps the self-rotating shaft rotating unidirectionally, and reduces empty dosing and repeated dosing on the return trip.
[0025] Preferably, when the buoyancy roller assembly floats, the single-stroke shaft drives the arm shaft to rotate through the bin frame gear ring, auxiliary gear, and arm gear. The crankshaft drives the rubber hammer to vibrate the outside of the inclined bin through the first and second traction arms. This synchronously transmits the rotational power of the single-stroke shaft to the auxiliary drug delivery arm assembly, so that the rubber hammer synchronously vibrates the inclined bin during the drug delivery start-up process, ensuring that the filtered drug powder continuously enters the drug delivery tank.
[0026] Preferably, when the dosing roller rotates within the dosing hopper, the dosing trough on the dosing roller rotates between the top hopper and the storage hopper to dosing and conveying the powder. The rotating gear meshes with the outer edge of the traveling gear ring and rotates. The stirring blades on the stirring shaft rotate and stir the powder within the dosing trough to discharge it. This allows the stirring blades to loosen and push the powder in the dosing trough while the dosing roller rotates to convey the powder, reducing the adhesion, blockage, and bridging of the powder within the dosing trough.
[0027] Compared with the prior art, the beneficial effects of this application are:
[0028] 1. This application utilizes the buoyancy change of the liquid in the storage tank to form a mechanical linkage, which enables the dosing structure to operate automatically when the liquid level rises. The rotation of the dosing structure is controlled according to the rise in liquid level, so that the amount of filter powder added is matched with the amount of liquid in the storage tank. This achieves automatic start-up, quantitative dosing and automatic control without the participation of external power, reducing the energy consumption of the device and the cost of electrical control. At the same time, the filter powder is transported in a relatively closed state, which can reduce the phenomenon of powder scattering, moisture absorption and water vapor backflow.
[0029] 2. This application adopts a double floating roller structure that can rotate synchronously in opposite directions to replace the traditional fixed floating plate. After the filtered powder falls, it can be evenly dispersed into the liquid storage tank under the rotation of the double floating roller, avoiding the fixed floating plate from blocking the falling powder. At the same time, the floating roller can agitate the liquid in the liquid storage tank during rotation, which can accelerate the diffusion, wetting and dissolution of the filtered powder, improve the uniformity of the mixing of powder and liquid, and reduce the local accumulation of powder.
[0030] 3. This application uses a one-way transmission structure to drive the dosing structure when the liquid level rises, and cuts off the reverse power transmission when the liquid level falls, thereby avoiding continuous dosing during the liquid level drop and reducing the risk of repeated dosing and overdosing. In addition, during the dosing process, the inclined chamber can be vibrated and the filtered powder in the dosing tank can be stirred at the same time, reducing powder adhesion, clogging and bridging, and improving the continuity of dosing, the accuracy of dosing and the reliability of the equipment operation.

[0060] The working principle of this application is as follows: In existing water pollution treatment processes, such as Figure 1 As shown, a filter disc is installed inside the filter cartridge 103. In actual use, when filtering is performed inside the filter cartridge 103, the filter disc alone can only achieve mechanical filtration and interception. However, the liquid may contain fine suspended solids, colloidal impurities, or fine contaminants that are not easily intercepted by the filter disc alone. To solve the above problems, this application provides a dosing chamber assembly 200 inside the frame assembly 100. In actual use, filter powder is added to the top chamber 201 at the top of the dosing chamber assembly 200. The filter powder can be carbon powder, etc. In actual use, the top chamber is... The filter powder in 201 is added to the storage tank 207. After the powder and water are mixed in the storage tank 207, it is sent into the filter cylinder 103. At this time, the filter powder mixed with water plays two roles in the filter cylinder 103. First, it adsorbs oil, organic impurities, decomposition products, and some odor and color substances in the water. Second, it gradually forms a carbon powder filter layer on the surface of the filter disc in the filter cylinder 103. During filtration, small impurities are further intercepted through this filter layer, thereby improving the filtration accuracy. In the above way, the shortcomings of mechanical filtration by relying solely on the filter disc in the filter cylinder 103 can be made up.
[0061] Through the above structural configuration, this application achieves a combined enhancement of the mechanical filtration capacity of the filter cartridge 103 by the filter powder. Specifically, the filter powder enters the storage tank 207 from the top chamber 201 via the dosing chamber assembly 200, mixes with the hydrolysate to form a filter solution, and is then sent into the filter cartridge 103. On the one hand, the filter powder adsorbs oil, organic impurities, decomposition products, odors, and color substances in the water. On the other hand, it forms an auxiliary filtration layer on the surface of the filter disc, which performs secondary interception of fine suspended solids and colloidal impurities that are difficult for the filter disc to directly intercept. This process transforms simple mechanical filtration into a synergistic effect of adsorption treatment and powder layer filtration. It can improve the pollutant removal range and filtration accuracy without changing the original filter disc structure of the filter cartridge 103, making up for the problem of insufficient treatment capacity of traditional filter discs for fine pollutants, and improving the water pollution treatment effect and the comprehensive applicability of the filter cartridge 103.
[0062] It should be noted that the filter disc inside the filter cartridge 103, the pipe connection between the filter cartridge 103 and the liquid storage tank 207, and the inlet and outlet channels inside the liquid storage tank 207 are all existing technologies, so they will not be described in detail.
[0063] Based on the aforementioned water pollution treatment, the filter powder in the top chamber 201 needs to be added to the storage tank 207 for hydrolysis before being sent to the filter cartridge 103 for use. This process presents several problems: since the filter powder is stored in the top chamber 201, when hydrolysis is required during water pollution treatment, it's crucial to determine when to add the filter powder from the top chamber 201 to the storage tank 207, how to control the amount of filter powder added to the storage tank 207, and when to open and close the dosing channel between the top chamber 201 and the storage tank 207. To address these issues, this application provides a metering roller assembly 500 between the top chamber 201 and the storage tank 207, and a buoyancy roller assembly within the storage tank 207. 300. In actual use, when hydrolysate enters the storage tank 207, the buoyancy of the hydrolysate causes the buoyancy roller assembly 300 to float upwards. This upward movement of the buoyancy roller assembly 300 triggers the rotation of the metering dosing roller assembly 500. Through the rotation of the metering dosing roller assembly 500, the filtered powder in the top tank 201 is added to the storage tank 207. By controlling the amount of hydrolysate in the storage tank 207, the upward height of the buoyancy roller assembly 300 is controlled. The upward height of the buoyancy roller assembly 300 controls the number of rotations of the metering dosing roller assembly 500, which in turn controls the amount of medicine added. Simultaneously, the rotation of the metering dosing roller assembly 500 between the top tank 201 and the storage tank 207 ensures that the top tank 201 and... In a closed state, the dosing channel between the storage tanks 207 performs rotational dosing. Specifically, when the amount of hydrolysate flowing into the storage tank 207 increases, buoyancy causes the first float roller 301 and the second float roller 303 to float upwards within the storage tank 207. During this upward floating process, the float roller tooth arm 305 moves upwards. The float roller tooth arm 305, through meshing with the single-stroke gear 602, drives the single-stroke shaft 601 to rotate. The single-stroke shaft 601, through the single-stroke ratchet 603 and pawl 604, drives the drive chamber frame 606 to rotate. The drive chamber frame 606, through the self-rotating shaft 506, drives the dosing roller 501 to rotate. The dosing roller 501 is rotatably positioned within the dosing chamber 203. When the dosing roller 501 rotates, the filter powder in the top chamber 201 falls into the dosing trough 502. As the dosing roller 501 rotates continuously, the filter powder in the dosing tank 502 falls into the storage tank 207. The rotation of the dosing roller 501 within the dosing hopper 203 ensures the constant sealing of the material discharge channel in the top hopper 201. Simultaneously, the up-and-down rotation of the dosing tank 502 allows for the quantitative dispensing and addition of filter powder from the top hopper 201. In this way, as the water level in the storage tank 207 rises, the buoyancy roller assembly 300 floats higher. The more rotations the quantitative dosing roller assembly 500 makes, the more filter powder is added. Furthermore, during water pollution treatment, the amount of filter powder added is directly proportional to the water level in the storage tank 207. Even the timing of filter powder addition is directly controlled by the upward movement of the buoyancy roller assembly 300.Simultaneously, the rotation of the metering roller assembly 500 is automatically triggered by the rising of the floating roller toothed arm 305, which drives the single-stroke gear 602; no external power is required.
[0064] Through the above structural configuration, this application achieves the capability of automatic start-up, automatic metering, and closed-loop delivery of chemical dosing based on changes in the liquid level of the storage tank 207. Specifically, after the hydrolysate enters the storage tank 207, it pushes the first float roller 301 and the second float roller 303 to float upwards. The float roller tooth arm 305 sequentially passes through the single-pass gear 602, the single-pass shaft 601, the single-pass ratchet 603, the pawl 604, and the drive frame 606, converting the linear upward motion into the rotation of the self-rotating shaft 506 and the dosing roller 501. The dosing tank 502 follows the rotation of the self-rotating shaft 506 and the dosing roller 501. The dosing roller 501 circulates between the top chamber 201 and the storage chamber 207 to pick up and release materials. The floating height of the buoyancy roller assembly 300 determines the number of rotations of the dosing roller 501, thereby establishing a mechanical correspondence between the amount of filter powder added and the increase in hydrolysate in the storage chamber 207. This process can complete the determination of the timing of dosing, the control of the amount of dosing, and the sealing and isolation of the dosing channel without relying on motors, sensors, or controllers, avoiding errors in manual dosing, powder scattering and moisture absorption, and water vapor backflow, thus improving the accuracy of dosing, energy utilization efficiency, and operational reliability.
[0065] Based on the above, when the metering dosing roller assembly 500 rotates, the dosing trough 502 on the metering dosing roller assembly 500 rotates and transports the filter powder in the top chamber 201 to the storage chamber 207. If a traditional float plate structure is used, i.e., the float plate is set on the hydrolysate in the storage chamber 207, the filter powder falling from the dosing trough 502 will fall directly onto the float plate, affecting the filter powder's entry into the storage chamber 207 for hydrolysis. Furthermore, the fixed position of the filter powder falling from the dosing trough 502 will cause the filter powder to... The liquid distribution within the storage tank 207 is not ideal. To overcome this problem, the buoyancy roller assembly 300 of this application is equipped with a second float roller 303 and a first float roller 301. The second gear 304 on the second float roller 303 meshes with the first gear 309 on the first float roller 301. Simultaneously, a traveling gear arm 209 is fixedly installed inside the end protection chamber 214. The second gear 304 meshes with the traveling gear arm 209. When the buoyancy roller assembly 300 floats, the second gear 304 moves along the traveling gear arm 209. At this time, the second float roller 303 and the first float roller 301 form a synchronous reversing structure through the meshing of the second gear 304 and the first gear 309. Through this structure, the traditional fixed float plate structure is changed into a bidirectional reversing float roller structure. The bidirectional reversing float rollers cause the filter powder falling from the metering dosing roller assembly 500 to fall onto the second float roller 303 and the first float roller 301. During the rolling process of the second float roller 303 and the first float roller 301, the filter powder is evenly distributed in the liquid storage tank 207. Inside, the rotation of the convex roller head 302 on the second float roller 303 and the first float roller 301 simultaneously agitates the hydrolysate in the storage tank 207, accelerating the uniform distribution of the filter powder in the storage tank 207. On the other hand, the synchronously rolling second float roller 303 and first float roller 301 do not obstruct the addition and fall of the filter powder. At the same time, the rolling of the second float roller 303 and the first float roller 301 is automatically triggered by the second gear 304 meshing and moving on the walking gear arm 209, without the need for external power.
[0066] Through the above structural configuration, this application achieves an integrated, non-powered synergistic capability of buoyancy response, powder dispersion, and hydrolysis stirring. Specifically, during the upward movement of the buoyancy roller assembly 300, the second floating roller 303 rotates along the traveling toothed arm 209 via the second gear 304. The meshing of the second gear 304 with the first gear 309 drives the first floating roller 301 to rotate synchronously in the opposite direction. This causes the filter powder falling from the dosing tank 502 to first fall onto the surface of the two sets of opposing rolling floating rollers, and then be dispersed and transported to different areas of the storage tank 207. At the same time, the convex roller heads 302 on the first floating roller 301 and the second floating roller 303 continuously disturb the hydrolysate, promoting the wetting, diffusion, and dissolution of the powder. This process replaces the traditional fixed floating plate with a double floating roller rolling structure, which retains the liquid level floating response function and avoids the floating plate blocking the dosing path and the local accumulation of powder. It can improve the uniformity of powder-water mixing, dissolution efficiency, and stability of the subsequent filtered solution without the need for independent stirring power.
[0067] Based on the above, it should be noted that after the filter powder and hydrolysate are mixed in the storage tank 207, they are pumped into the filter cartridge 103 by an external pump. At this time, the liquid level in the storage tank 207 drops, and the buoyancy roller assembly 300 also descends. When the buoyancy roller assembly 300 descends, if the metering dosing roller assembly 500 rotates accordingly, the filter powder in the top tank 201 will continue to be added to the storage tank 207. However, when the liquid level in the storage tank 207 drops back down, it is not necessary to add more powder. To solve the above problem, this application provides a one-way drive wheel assembly 600. When the buoyancy roller assembly 300 floats, the one-way shaft... The lever 601 drives the self-rotating shaft 506 to rotate unidirectionally via a single-pass ratchet 603, a pawl 604, and a drive chamber frame 606. When the liquid level in the storage tank 207 drops, the buoyancy roller assembly 300 descends. At this time, the float roller tooth arm 305 drives the single-pass shaft 601 to rotate in the opposite direction via a single-pass gear 602. At this time, the single-pass ratchet 603 on the single-pass shaft 601 will not transmit power to the drive chamber frame 606 via the pawl 604, and thus will not transmit power to the self-rotating shaft 506. At this time, the metering dosing roller assembly 500 stops rotating. Through this structure, the automatic stop of dosing is achieved when the liquid level in the storage tank 207 drops.
[0068] Through the above structural configuration, this application achieves a one-way control capability that transmits dosing power only during the liquid level rise phase and automatically disconnects power during the liquid level fall phase. Specifically, when the buoyancy roller assembly 300 floats, the single-stroke shaft 601 drives the single-stroke ratchet 603 to rotate forward, and the clamping spring 605 keeps the pawl 604 in effective contact with the single-stroke ratchet 603, thereby driving the drive chamber frame 606 and the self-rotating shaft 506 to rotate and complete the dosing; when the liquid level in the storage tank 207 drops, the floating roller tooth arm... 305 drives the single-stroke shaft 601 in the reverse direction via the single-stroke gear 602. The single-stroke ratchet 603 slides across the pawl 604 during idle travel, and the reverse power cannot be transmitted to the drive chamber frame 606 and the quantitative dosing roller assembly 500. This process uses the pure mechanical ratchet and pawl cooperation to form liquid level direction recognition. It can prevent repeated dosing and overdosing during the liquid discharge process without relying on program judgment or electronic clutch. It ensures that each dosing action corresponds to only the newly added hydrolysate, improving the stability of the drug solution ratio and the reliability of the device's automatic control.
[0069] Based on the above, an auxiliary drug-feeding arm assembly 400 is provided on the outer side of the inclined chamber 202 in this application. When the drive chamber frame 606 rotates, the drive chamber frame 606 drives the crankshaft 403 to rotate through the chamber frame gear ring 607 and the arm gear 402. When the crankshaft 403 rotates, the crankshaft 403 pulls the second traction arm 405 to slide back and forth on the side wing frame 215 through the first traction arm 404, thereby realizing the vibration of the rubber hammer head 406 on the outer side of the inclined chamber 202, so that the filter powder in the top chamber 201 can pass through the inclined chamber 202. The powder smoothly enters the dosing tank 502 on the quantitative dosing roller assembly 500, avoiding obstruction of the dosing of the filtered powder. At the same time, the dosing tank 502 is equipped with a stirring shaft 504 with stirring blades 503. One end of the stirring shaft 504 is equipped with a self-rotating gear 505. When the quantitative dosing roller assembly 500 rotates, the self-rotating gear 505 meshes and moves around the outer periphery of the traveling gear ring 210. In this way, the self-rotation of the stirring shaft 504 is realized, thereby preventing the filtered powder from bridging in the dosing tank 502 and avoiding obstruction of the dosing.
[0070] Through the above structural configuration, this application achieves a dual anti-clogging capability by simultaneously using the dosing driving force for both the inclined bin vibration feeding and the internal stirring discharge of the dosing tank. Specifically, when the drive bin frame 606 rotates, it drives the arm shaft 401 and crankshaft 403 to rotate through the bin frame gear ring 607, auxiliary gear 213, and arm gear 402. The crankshaft 403 converts the rotational motion into the reciprocating vibration of the rubber hammer head 406 via the first traction arm 404 and the second traction arm 405, thereby discharging the excess material adhering to or bridging the inner wall of the inclined bin 202. The filtered powder is loose and continuously falls into the dosing tank 502; at the same time, the rotating gear 505 meshes and rotates along the traveling gear ring 210, driving the stirring shaft 504 and stirring blade 503 to rotate in the dosing tank 502, stirring and dispersing the powder in the tank. This process uses the mechanical power formed by the buoyancy of the same liquid level to simultaneously eliminate the blockage of the inclined chamber 202 channel and the bridging inside the dosing tank 502. It can improve the continuity of drug addition, the integrity of quantitative material taking, and the stability of the dosing process without the need for a separate vibration motor or stirring motor.
