Description

Technical Field

[0001] This application relates to the field of powder removal equipment technology, and in particular to a high-level tablet closed upward rotating powder removal screen. Background Technology

[0002] With the rapid development and application of highly active and toxic solid dosage forms such as anti-tumor drugs in the market, the demand for highly sealed equipment is increasing. As a component of tablet production, the dust removal screen must also meet the requirements of a sealed environment, enabling the tablets to be dusted and lifted within a closed system. Firstly, the sealing requirement must be addressed to prevent dust leakage and pollution during production. Secondly, the dust removal screen should be easy to operate and use, meeting the needs of a wider range of users.

[0003] Currently, the upper working chamber and the lower vibrating body chamber of the powder separator are connected, making it easy for dust to contaminate the vibrating body and increasing its failure rate. The powder separator's outer casing is generally a single piece, making disassembly and assembly quite heavy when height needs to be increased. Furthermore, the relative positions of the inlet and outlet in the circumferential direction are fixed and cannot be adjusted. This means that when the inlet is used in conjunction with the tablet press's outlet, the fixed outlet position restricts the tablet collection device's placement, making it inconvenient to arrange within a given room space. Summary of the Invention

[0004] This application proposes a high-level, enclosed, upward-rotating tablet de-dust sieve. The sieve body and outer cover adopt a segmented structure, which facilitates disassembly and installation by the operator. The inlet and outlet can be adjusted 360 degrees in all directions relative to each other in the circumferential direction. The high-level design of the outlet provides space for downstream equipment connection and meets the needs of more users.

[0005] This application provides a high-level tablet sealed top-rotating de-dust sieve, comprising: a base frame, an outer cover, a vibrating body, and an inner spiral conveying channel. A controller is installed on the base frame, and casters are installed under the base frame. The height of the de-dust sieve is adjusted by the extension and retraction of a lifting rod on the base frame via a spring.

[0006] The outer cover includes a top outer cover, a middle outer cover, a lower outer cover, and a vibrating body outer cover. The top outer cover, middle outer cover, lower outer cover, and vibrating body outer cover are connected to each other by quick-release clamps. The lower outer cover is provided with a feed inlet. The tablets enter the bottom end of the spiral conveying channel inside the outer cover through the feed inlet. The spiral conveying channel is installed on the vibrating body by a column. The middle outer cover is provided with a discharge outlet.

[0007] The top of the outer cover is equipped with a filter, which is connected to the working chamber inside the outer cover. The working chamber inside the outer cover is equipped with a cleaning spray nozzle, which is fixed to the lower outer cover, the middle outer cover, and the top outer cover respectively.

[0008] Furthermore, the spiral conveying channel is provided with sieve holes.

[0009] Furthermore, both the inlet and outlet are equipped with quick-release sealed observation windows.

[0010] Furthermore, quick-install sealing clamps are provided at the docking positions of the feed inlet and the upstream equipment, as well as the docking positions of the discharge outlet and the downstream equipment.

[0011] Furthermore, a powder collection tray is provided at the bottom of the working chamber inside the outer cover, and an elastic connecting tube is connected to the lower part of the powder collection tray. A dust suction port and a drain port are provided at the other end of the elastic connecting tube, wherein the dust suction port opens to the side of the elastic connecting tube.

[0012] Furthermore, the powder collection tray is equipped with a sealing gasket, and the sealing gasket, the lower outer cover, and the vibrating outer cover are connected by quick-release clamps. The internal working cavity of the outer cover and the vibrating body cavity of the vibrating outer cover are sealed and isolated by the sealing gasket.

[0013] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0014] This application features quick-release sealing clamps at both the inlet / outlet connection points with upstream equipment and the outlet / outlet connection points with downstream equipment, significantly improving the overall sealing performance of the equipment and reducing dust leakage during production. The outer cover, screen body, observation window, and air inlet filter all adopt a quick-release structure, allowing for rapid disassembly, removal, and maintenance. The powder collection tray is equipped with a sealing gasket, which, along with the lower outer cover and the vibrator outer cover, is connected by quick-release clamps. This facilitates operation and prevents dust and cleaning water from entering the lower vibrator, reducing the likelihood of damage to the vibrator.

[0015] The discharge port and inlet of this application can be adjusted 360 degrees in circumferential direction, facilitating docking between the inlet and upstream equipment and between the discharge port and downstream equipment. This design allows for convenient placement and saves space. The high-level design of the discharge port provides space for connecting downstream equipment to a higher floor, meeting the high-level tablet collection device requirements of more users.

[0016] This application features 360° water spray cleaning within the working chamber, allowing for thorough dust removal after operation and reducing the health risks to operators. The fully enclosed design isolates the internal chamber from the outside environment and is equipped with a high-efficiency air intake filter. During operation, negative pressure is maintained to prevent dust leakage and ensure production safety.

[0017] This application has quick-release sealed observation windows next to the inlet and outlet of the outer cover, allowing operators to view the spiral area from an excellent perspective at any time and to visually monitor the production process at any time. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of this application. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, this application proposes a high-level tablet sealed top-rotating de-dust sieve, including: a base frame 1, an outer cover 2, a vibrating body 3, and an inner cavity spiral conveying channel 4. A controller 18 is installed on the base frame 1, and casters 5 are installed under the base frame 1. The lifting rod 6 on the base frame 1 adjusts the height of the de-dust sieve by means of spring extension and retraction.

[0023] The outer cover 2 includes a top outer cover 21, a middle outer cover 22, a lower outer cover 23, and a vibrating body outer cover 31. The top outer cover 21, the middle outer cover 22, the lower outer cover 23, and the vibrating body outer cover 31 are connected to each other by quick-release clamps 7. The lower outer cover 23 is provided with a feed inlet 9. The tablets enter the bottom end of the spiral conveying channel 4 inside the outer cover 2 through the feed inlet 9. The spiral conveying channel 4 is installed on the vibrating body 3 by a column 10. The middle outer cover 22 is provided with a discharge outlet 13.

[0024] The top of the outer cover 21 is equipped with a filter 8, which is connected to the working chamber inside the outer cover 2. The working chamber inside the outer cover 2 is equipped with a cleaning spray nozzle 15, which is fixed on the lower outer cover 23, the middle outer cover 22, and the top outer cover 21 respectively.

[0025] The spiral conveyor channel 4 is equipped with screen holes. Quick-release sealed observation windows are located next to the inlet 9 and outlet 13. Quick-release sealing clamps 14 are installed at the docking points of the inlet 9 and upstream equipment, and the outlet 13 and downstream equipment. A powder collection tray 16 is installed at the bottom of the working chamber inside the outer cover 2. The lower part of the powder collection tray 16 is connected to an elastic connecting pipe. The other end of the elastic connecting pipe has a dust suction port 161 and a drain port 162, with the dust suction port 161 opening onto the side of the elastic connecting pipe. A sealing gasket 17 is installed on the powder collection tray 16. The sealing gasket 17, the lower outer cover 23, and the vibrating outer cover 31 are connected by quick-release clamps 7. The internal working chamber of the outer cover 2 and the vibrating chamber of the vibrating outer cover 31 are sealed and isolated by the sealing gasket.

[0026] The design principle of this application is:

[0027] The base frame 1 is equipped with casters 2 for easy movement; the lifting rod 6 on the base frame 1 adjusts the height of the powder removal screen by means of spring extension and retraction, thereby adjusting the height of the feed inlet and discharge outlet.

[0028] The outer casing 2, comprising a top outer casing 21, a middle outer casing 22, a lower outer casing 23, and a vibrating outer casing 31, is connected by quick-release clamps 7. This allows for 360-degree omnidirectional adjustment of the relative positions of the discharge port 13 of the middle outer casing and the inlet 9 of the lower outer casing in the circumferential direction. This facilitates docking of the inlet 9 with upstream equipment (tablet press) and the discharge port 13 with downstream equipment (metal detector, tablet collection bin, or packaging machine). The casing is conveniently positioned and saves space. The multi-section casing structure facilitates disassembly and installation by the operator, and makes maintenance convenient.

[0029] The top of the outer cover 21 is equipped with a filter 8, which is connected to the working chamber inside the outer cover 2. After being filtered by the filter 8, the outside air enters the internal working chamber, which promptly compensates for the pressure in the working chamber, increases airflow, facilitates the removal of dust in the working chamber, and also prevents the pressure in the working chamber from being too low, which could damage the equipment.

[0030] The lower outer cover 23 is provided with a feed inlet 9. The tablets enter the bottom of the spiral conveying channel 4 inside the outer cover through the feed inlet 9. The spiral conveying channel 4 is provided with sieve holes. The spiral conveying channel 4 is installed on the vibrating body 3 through the column 10. Under the vibration of the vibrating body 3, the spiral conveying channel 4 drives the tablets to rotate and roll upward along the conveying channel. During the rolling and upward movement of the tablets, the sieve holes on the conveying channel remove the dust and burrs on the surface of the tablets. Most of the dust generated is sucked away through the dust suction port. Finally, the tablets are discharged through the discharge port 13 on the middle outer cover, completing the tablet polishing, dust removal and high-level conveying process.

[0031] The outer cover 2 has quick-release sealed observation windows (not shown in the figure) next to the inlet 9 and outlet 13. Operators can view the conveying channel area from a good angle at any time, so that the production process can be visually monitored at any time.

[0032] Quick-release sealing clamps 7 are installed at the docking positions of the feed inlet 9 and the upstream equipment (tablet press) and the discharge outlet 13 and the downstream equipment (metal detector or tablet collection barrel or packaging machine), which greatly improves the sealing performance of the entire set of equipment and reduces dust leakage during the production process.

[0033] The inner working chamber of the outer cover 2 is equipped with cleaning spray nozzles 15, which are fixed to the lower outer cover, middle outer cover, and top outer cover respectively. After the work is completed, the working chamber can be sprayed with water to clean it 360 degrees without dead angles, rinsing away any remaining dust. A dust collection tray 16 is set at the bottom of the inner working chamber of the outer cover 2. The dust collection tray 16 collects the dust (rinsing water) through a flexible connecting pipe and is collected by a vacuum (drain) port below. The vacuum port below is connected to a vacuum cleaner to remove the dust during operation, and the drain port below is connected to a sewage treatment system to collect the rinsing water in the working chamber after the work is completed. The dust collection tray 16 is equipped with a sealing gasket 17. The sealing gasket 17, the lower outer cover 23, and the vibrating body outer cover 31 are connected by quick-release clamps. The upper working chamber and the lower vibrating body chamber are sealed and isolated by the sealing gasket, which can prevent dust and cleaning water from entering the lower vibrating body and reduce the chance of damage to the vibrating body.

[0034] In summary, this utility model is specifically designed for polishing, dust removal, and high-level conveying of tablets containing anticancer drugs, highly allergenic drugs, and other medications that pose certain risks to human health and the environment. The upward-rotating dust removal screen features a multi-segmented, modular outer casing connected by quick-release sealing. The inlet and outlet can be adjusted 360 degrees omnidirectionally. The high-level outlet design provides space for downstream equipment connections, meeting the requirements of more users for high-level tablet collection devices. A sealing gasket is added between the internal working chamber and the cavity of the lower vibrating body to prevent dust from entering and causing contamination. Both the inlet and outlet utilize quick-release sealing devices for connection with supporting equipment. A cleaning nozzle is added to the working chamber for cleaning after operation. This reduces the risk to operator health when the outer casing is opened for further cleaning. Due to its sealed structure, a large negative pressure is prevented from forming in the working chamber when an external vacuum cleaner is connected to the sealed top-rotating dust removal screen suction port. A high-efficiency filter is installed on the top cover. Through the filter, the internal working chamber is connected to the outside air. After being filtered, the outside air enters the working chamber inside the outer cover, which timely compensates for the pressure in the working chamber, increases airflow, and facilitates the removal of dust in the working chamber. At the same time, it also prevents the pressure in the working chamber from being too low, which could damage the equipment.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
