Description

Technical Field

[0001] This utility model relates to the field of solid dosage form production technology, and in particular to a centralized dust collection mechanism. Background Technology

[0002] In solid dosage form production lines, dust is generated during processes such as crushing, sieving, tableting, coating, and filling. Specifically, during crushing and sieving, raw materials need to be broken down into particle sizes suitable for production, which generates a large amount of dust. Similarly, during tableting and granule capsule filling, although the equipment has high airtightness and dust collection devices, dust still flies when adding raw materials and discharging. In addition, although high-efficiency coating machines operate in a closed space during the coating process, the tumbling of materials during operation also generates dust.

[0003] The existing production line uses stand-alone vacuum cleaners to ensure a dust-free workshop. However, these vacuum cleaners cause the room temperature to rise and generate significant noise, making the environment unfavorable for worker productivity. Therefore, a mechanism is needed that can centrally collect dust and reduce the impact of temperature and noise. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where production lines use single-unit vacuum cleaners to ensure a dust-free workshop, but these vacuum cleaners cause room temperature to rise and generate significant noise, making the indoor environment unfavorable for workers' production. Therefore, a centralized vacuuming mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centralized dust collection mechanism includes a bag filter, wherein the air inlet of the bag filter is fixedly connected to an outdoor air inlet pipe, and one end of the outdoor air inlet pipe extends into the factory building, and one end of the outdoor air inlet pipe is provided with an air inlet assembly for arrangement in the factory building.

[0007] A fan is used to drive the flow of gas. The fan is located on one side of the bag filter. The air outlet of the bag filter and the air inlet of the fan are fixedly connected by the same connecting pipe. The air outlet of the fan is fixedly connected to an air outlet pipe, and one end of the air outlet pipe extends into the factory building. The outer wall of the air outlet pipe is provided with multiple air outlets.

[0008] A dust discharge assembly is used for discharging and storing dust. The dust discharge assembly is located below the bag filter. The dust discharge assembly includes a storage box and an inner connecting shell that is slidably disposed inside the storage box. The top of the inner connecting shell extends into the interior of the bag filter. A sealing plate is disposed on one side of the bag filter, and one end of the sealing plate slides through the bag filter and the inner connecting shell.

[0009] In one possible design, a side plate is fixedly installed on one side of the bag filter, and a clamping rod is installed above the side plate. The clamping rod slides through the side plate and the sealing plate. An outer ring is fixedly fitted on the outer wall of the clamping rod, and a tension spring is fitted on the outer wall of the clamping rod. The two ends of the tension spring are respectively fixedly installed at the bottom of the outer ring and the top of the side plate.

[0010] In one possible design, the ash discharge assembly further includes an inverted truncated cone cylinder and a sealing block. The inverted truncated cone cylinder is fixedly installed on the inner wall of the inner connecting shell and is located below the sealing plate. The sealing block is fixedly installed inside the storage box by a bracket, and the top of the sealing block and the bottom of the inverted truncated cone cylinder cooperate with each other.

[0011] In one possible design, the top of the sealing block is set as a slope.

[0012] In one possible design, a push plate is fixedly installed on one side of the inner connecting shell, and a side groove is opened on one side of the bag filter, with the push plate located inside the side groove.

[0013] In one possible design, the air intake assembly includes multiple indoor connecting pipes. One end of both the outdoor air intake pipe and the indoor connecting pipe is fixedly provided with an inner ring. The other end of the outer wall of the indoor connecting pipe is fitted with a threaded cylinder, which is threaded onto the outer wall of the inner ring. The outer wall of the indoor connecting pipe is provided with at least one air intake end.

[0014] In one possible design, the outer walls of both the outdoor air intake pipe and the indoor connecting pipe are fixedly fitted with retaining rings, with the retaining rings positioned on the side closest to the inner ring. The outer walls of both the outdoor air intake pipe and the indoor connecting pipe are slidably fitted with sliding rings, with the sliding rings positioned between the retaining rings and the inner ring. A common compression spring is provided between the sliding rings and the retaining rings. Multiple inserts are fixedly provided on one side of the sliding ring, and multiple slots are provided on one side of the threaded cylinder, with each slot engaging with a multiple insert.

[0015] In this application, during practical use, the gas, along with dust, is drawn in through the inlet end via an indoor connecting pipe installed inside the factory building. Then, it enters the bag filter through the indoor connecting pipe and the outdoor inlet pipe. The dust is filtered by the dust bags inside the bag filter, and the purified gas then enters the outlet pipe through a connecting pipe and a fan, and is then transported back into the factory building through the outlet end. For the connection between the two indoor connecting pipes, and between the outdoor inlet pipe and the indoor connecting pipe, first, one end of the indoor connecting pipe is inserted into the inner ring to establish connection. Then, the threaded cylinder is rotated, causing the threaded cylinder to be initially fixed against the outer wall of the inner ring. Simultaneously, the sliding ring is pulled, causing the sliding ring to move the insert block. When the threaded cylinder is securely fitted against the outer wall of the inner ring and the insert block and slot correspond, the sliding ring is reset by the force of a compression spring, causing the insert block to lock into the slot, preventing the threaded cylinder from rotating. This further ensures the stability of the connection. By using indoor connecting pipes of different shapes, the inlet end can be easily installed in areas with high dust levels. For the collection and discharge of dust inside the baghouse dust collector, when cleaning is required, pull the lever to detach it from the sealing plate. The sealing plate can then be moved to one side, ensuring the inner connecting shell and the baghouse dust collector remain connected. The storage box and the baghouse dust collector are then connected. At this point, the pulse assembly inside the baghouse dust collector shakes the dust out of the filter bags, which then enters the storage box through the inverted square-shaped cylinder for storage. When cleaning the dust inside the storage box is needed, simply pull out the sealing plate, disconnecting the baghouse dust collector from the inner connecting shell. The inner connecting shell will then fall into the storage box, and the top of the sealing block will seal the bottom of the inverted square-shaped cylinder, automatically sealing the storage box and preventing leakage during movement. Afterwards, simply move the storage box back to below the baghouse dust collector, and use the moving push plate to move the inner connecting shell back into the baghouse dust collector. Then, insert the sealing plate back into its original position and secure it with the lever.

[0016] In this utility model, the centralized dust collection mechanism, through the air intake component, can facilitate the arrangement of indoor connecting pipes in the factory, thereby allowing users to place the air intake end in the place where dust is concentrated in the factory, thus improving the dust collection efficiency.

[0017] In this utility model, the centralized dust collection mechanism, through the dust discharge component, can achieve convenient collection and storage of dust through a simple structure, so as to transport it away for cleaning;

[0018] In this invention, multiple interconnectable indoor connecting pipes allow users to easily install the air inlet at locations where dust is concentrated, facilitating collection. The dust is then filtered by a bag filter installed outside the factory, reducing noise and temperature effects. Furthermore, the dust collection and processing using the bag filter is relatively convenient compared to traditional methods. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1A dust collection mechanism includes: a bag filter 1, an outdoor air inlet pipe 2, a fan 7, and a dust removal assembly. The air inlet of the bag filter 1 is fixedly connected to the outdoor air inlet pipe 2, one end of which extends into the interior of the factory building to draw dust-laden gas from the factory building into the bag filter 1. An air intake assembly is provided at one end of the outdoor air inlet pipe 2, and the air intake assembly includes multiple indoor connecting pipes 3 arranged within the factory building to draw in dust-laden gas from multiple locations.

[0029] The outlet of the bag filter 1 and the inlet of the fan 7 are fixedly connected by a connecting pipe 8. The fan 7 is used to drive the flow of gas, extracting the gas purified by the bag filter 1 and discharging it through the outlet pipe 6. One end of the outlet pipe 6 extends into the factory building, and multiple outlet ends 5 are provided on the outer wall of the outlet pipe 6 to evenly discharge the purified gas back into the factory building, forming a gas circulation.

[0030] This application can be used in the field of solid dosage form production, or in other fields applicable to this application.

[0031] Example 2

[0032] refer to Figure 2-3 An improvement upon Example 1: A centralized dust collection mechanism applied to the production of solid dosage forms. A dust discharge assembly is positioned below the bag filter 1 for discharging and storing dust. The dust discharge assembly includes a storage tank 9, an inner connecting shell 11, an inverted square-shaped cylinder 10, and a sealing block 15. The inner connecting shell 11 is slidably disposed inside the storage tank 9, with its top extending into the interior of the bag filter 1 to receive dust collected in the bag filter 1. The sealing plate 12 is slidably disposed on one side of the bag filter 1 and within the inner connecting shell 11 to control the connection between the inner connecting shell 11 and the bag filter 1.

[0033] To secure the sealing plate 12, a side plate 14 is fixedly installed on one side of the bag filter 1. A locking rod 13 is installed above the side plate 14, and the locking rod 13 slides through the side plate 14 and the sealing plate 12. An outer ring 23 is fixedly fitted onto the outer wall of the locking rod 13, and a tension spring is also fitted onto the outer wall of the locking rod 13. The two ends of the tension spring are respectively fixed to the bottom of the outer ring 23 and the top of the side plate 14. When it is necessary to open the sealing plate 12, the outer ring 23 can be pulled outward to allow the locking rod 13 to slide out of the sealing plate 12, thereby releasing the fixation of the sealing plate 12.

[0034] The inverted truncated cone cylinder 10 is fixedly installed on the inner wall of the inner connecting shell 11 and located below the sealing plate 12. The sealing block 15 is fixedly installed inside the storage box 9 by a bracket. The top of the sealing block 15 matches the bottom of the inverted truncated cone cylinder 10, and the top of the sealing block 15 is set as a slope.

[0035] Reference Figure 4-5A push plate 24 is fixedly installed on one side of the inner connecting shell 11, and a side groove 25 is opened on one side of the bag dust collector 1, with the push plate 24 located inside the side groove 25.

[0036] Specifically, when cleaning is required, by pulling the lever 13 to disengage it from the sealing plate 12, the sealing plate 12 can be moved to one side. While ensuring that the inner connecting shell 11 and the bag filter 1 are still connected, the storage box 9 and the bag filter 1 are connected. At this time, the dust in the filter bags is shaken out by the pulse component inside the bag filter 1 (a blowpipe is installed above each row of filter bags inside the bag filter 1, and a compressed air injection hole is opened on the blowpipe facing the center of each filter bag. The other end of the blowpipe is connected to a pulse control system composed of a pulse valve, a control valve, etc., and a compressed air storage tank. The dust on the surface of the filter bags is pulse-jet cleaned by high-speed gas). The dust enters the storage box 9 through the inverted square-shaped cylinder 10 for storage. When it is necessary to clean the dust inside the storage box 9, simply pull out the sealing plate 12 to disconnect the bag filter 1 from the inner connecting shell 11. At this time, the inner connecting shell 11 will fall into the storage box 9, and the top of the sealing block 15 will seal the bottom of the inverted square-shaped cylinder 10, thus automatically sealing the storage box 9 and preventing leakage during movement. Subsequently, simply move the storage box 9 back to below the bag filter 1, and move the inner connecting shell 11 back into the bag filter 1 using the moving push plate 24. Then, insert the sealing plate 12 back into its original position and secure it with the clamp 13.

[0037] Reference Figure 6 To facilitate the installation and connection of the indoor connecting pipe 3, an inner ring 21 is fixedly installed at one end of both the outdoor air intake pipe 2 and the indoor connecting pipe 3. A threaded cylinder 19 is fitted onto the other end of the outer wall of the indoor connecting pipe 3, and the threaded cylinder 19 is threaded onto the outer wall of the inner ring 21 on another pipe. To increase the stability of the connection, a fixing ring 16 is fixedly fitted onto the outer wall of both the outdoor air intake pipe 2 and the indoor connecting pipe 3, and the fixing ring 16 is located on the side close to the inner ring 21. A sliding ring 17 is also slidably fitted onto the outer wall of both the outdoor air intake pipe 2 and the indoor connecting pipe 3, and the sliding ring 17 is located between the fixing ring 16 and the inner ring 21. A common compression spring 22 is provided between the sliding ring 17 and the fixing ring 16. Multiple inserts 18 are fixedly installed on one side of the sliding ring 17, and multiple slots 20 are opened on one side of the threaded cylinder 19, and the multiple slots 20 respectively cooperate with the multiple inserts 18.

[0038] Specifically, firstly, insert one end of the indoor connecting pipe 3 into the inner ring 21 to achieve connection. Then, rotate the threaded cylinder 19 so that the threaded cylinder 19 is threaded onto the outer wall of the inner ring 21 for initial fixation. While rotating the threaded cylinder 19, first pull the sliding ring 17 so that the sliding ring 17 drives the insert block 18 to move. When the threaded cylinder 19 is securely fitted onto the outer wall of the inner ring 21 and the insert block 18 corresponds to the slot 20, the sliding ring 17 is reset by the force of the compression spring 22, so that the insert block 18 is locked into the inside of the slot 20, preventing the threaded cylinder 19 from rotating, thereby further ensuring the stability of the connection. By using indoor connecting pipes 3 of different shapes, the air inlet end 4 can be easily installed in places where a lot of dust is generated.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the bag filter 1 and the fan 7 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
