[0002] Hoppers are a very common component in pharmaceutical equipment. Because pharmaceutical manufacturing requires ensuring hygiene, hoppers need to be cleaned regularly. To facilitate cleaning, specific equipment is required for this purpose.

[0003] Conventional cleaning methods mostly involve stirring the cleaning solution in a hopper using a stirring paddle. However, since the position of the stirring paddle is fixed, the maximum cleaning effect is concentrated at the stirring paddle, resulting in uneven cleaning and poor results. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lifting double-chamber hopper cleaning device, which can increase the cleaning effect and can clean different height positions inside the hopper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting dual-chamber hopper cleaning device, comprising a lifting drive mechanism and a stirring mechanism; the stirring mechanism includes a stirring paddle, a rotating shaft, and a driver, the driver driving the stirring paddle to rotate via the rotating shaft; the rotating shaft includes a hollow shaft and a lifting shaft, the lifting shaft being coaxially inserted inside the hollow shaft and circumferentially fixed with the hollow shaft, the hollow shaft cooperating with the driver to rotate, the stirring paddle being fixedly installed at the end of the lifting shaft, the lifting shaft being connected to the lifting drive mechanism and being lifted and lowered via the lifting drive mechanism.

[0006] As a further improvement of this utility model, the stirring paddle includes a conical body and blades mounted on the side of the body, with the tip of the conical body located at the other end of the body opposite the lifting shaft; and when the blades rotate, they drive the cleaning fluid to flow toward the lifting shaft.

[0007] As a further improvement of this utility model, the main body includes a connecting seat and a replacement head. The connecting seat is fixedly connected to the lifting shaft, and the replacement head is fixedly connected to the connecting seat through a sealing flange. The replacement head is conical, and a secondary stirring blade is provided on the side of the replacement head.

[0009] As a further improvement of this utility model, the lifting drive mechanism includes a base plate, a cylinder mounted on the base plate, a plurality of guide columns vertically mounted on the base plate, and a lifting platform connected to the guide columns. The lifting shaft is mounted on the lifting platform through bearings.

[0010] As a further improvement of this utility model, the lifting shaft is provided with a radially protruding flange on one side of the replacement head, and the flange is fixedly connected to the connecting seat in conjunction with the sealing flange.

[0011] As a further improvement of this utility model, a drain port is also provided on the platform.

[0012] The beneficial effects of this invention are as follows: The hollow shaft is driven to rotate by a driver, which in turn drives the lifting shaft to rotate, thereby rotating the agitator and agitating the cleaning fluid.

[0016] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figure 1-2 As shown,

[0018] A lifting dual-chamber hopper cleaning device includes a lifting drive mechanism 1 and a stirring mechanism 2. The stirring mechanism 2 includes a stirring paddle 21, a rotating shaft 22, and a driver 23. The driver 23 drives the stirring paddle 21 to rotate through the rotating shaft 22. The rotating shaft 22 includes a hollow shaft 221 and a lifting shaft 222. The lifting shaft 222 is coaxially inserted inside the hollow shaft 221 and is circumferentially fixed with the hollow shaft 221. The hollow shaft 221 rotates in cooperation with the driver 23. The stirring paddle 21 is fixedly installed at the end of the lifting shaft 222. The lifting shaft 222 is connected to the lifting drive mechanism 1 and is lifted and lowered by the lifting drive mechanism.

[0019] The hollow shaft 221 is driven to rotate by the driver 23, which in turn drives the lifting shaft 222 to rotate, thereby rotating the agitator 21 and agitating the cleaning fluid for cleaning. The circumferential fixation between the hollow shaft 221 and the lifting shaft 222 can be achieved using a keyway fit. For example, a groove is cut in the hollow shaft 221, and a corresponding key is provided on the lifting shaft 222; the two fit together to achieve circumferential fixation. The lifting drive mechanism 1 can drive the lifting shaft 222 to move up and down, thereby adjusting the height of the agitator 21. This allows the agitator 21 to agitate the cleaning fluid at different heights, transferring the cleaning force to different height positions and improving the overall cleaning power.

[0020] In the specific configuration, the stirring paddle 21 includes a conical body 211 and a blade 212 installed on the side of the body 211. The tip of the conical body 211 is located at the other end of the body 211 opposite to the lifting shaft 222. When the blade 212 rotates, it drives the cleaning fluid to flow toward the lifting shaft 222.

[0021] The paddle 212 agitates the cleaning fluid downwards as shown in the figure, allowing the cleaning fluid to circulate. The conical body 211 further facilitates the circulation of the cleaning fluid, resulting in better vertical cleaning and more comprehensive cleaning.

[0022] To accommodate more hoppers, the main body 211 includes a connecting seat 2111 and a replacement head 2112. The connecting seat 2111 is fixedly connected to the lifting shaft 222, and the replacement head 2112 is fixedly connected to the connecting seat 2111 via a sealing flange 3. The replacement head 2112 is conical, and a secondary stirring blade 21121 is provided on the side of the replacement head 2112.

[0023] The replacement head 2112 has a secondary stirring blade 21121, and the replacement head 2112 itself is fixed to the connecting seat 2111 by the sealing flange 3. Therefore, the replacement head 2112 can be replaced, and different hoppers can be adapted by different secondary stirring blades 21121.

[0024] For ease of installation, the system also includes a frame 4 and a platform 5 mounted on the frame 4; the lifting drive mechanism 1 and the drive unit 23 are both mounted on the frame 4; the platform 5 is used to cooperate with the hopper for installation, and the end with the larger opening of the hopper is connected to the platform 5; a sealing ring 51 is provided on the side of the platform 5, and the sealing ring 51 abuts against the inner wall of the end with the larger opening of the hopper.

[0025] The frame 4 facilitates the installation of the lifting drive mechanism 1 and the driver 23. The sealing ring 51 on the platform 5 can be used to seal the opening of the hopper. For example, the larger end of the hopper opening can be placed on the platform 5, and then the sealing ring 51 of the platform 5 can be used to seal the hopper. The hopper has a larger opening and a smaller opening, and there is a transition with a smaller diameter between the two ends. This transition can be used in conjunction with the stirring action to increase the flow rate, and at the same time, it can also produce a certain anti-splash effect, thereby increasing the cleaning effect.

[0026] In a preferred embodiment, the lifting drive mechanism 1 includes a base plate 11, a cylinder 12 mounted on the base plate 11, a plurality of guide columns 13 vertically mounted on the base plate 11, and a lifting platform 14 connected to the guide columns 13. The lifting shaft 222 is mounted on the lifting platform 14 via bearings.

[0027] The lifting platform 14, in conjunction with the guide column 13, enables more stable lifting and lowering movement. The lifting shaft 222 is mounted on the lifting platform 14 via bearings, which maintains the rotation of the lifting shaft 222. Furthermore, the lifting and lowering action does not affect the rotation of the lifting shaft 222.

[0028] Cylinder 12 has a strong driving force and a certain buffering effect, resulting in a more stable driving effect.

[0029] To facilitate the fixing of the lifting shaft 222 with the replacement head 2112 and the connecting seat 2111, a radially protruding flange 2221 is provided on one side of the lifting shaft 222 corresponding to the replacement head 2112, and the flange 2221 is fixedly connected to the connecting seat 2111 in conjunction with the sealing flange 3.

[0030] The flange 2221 and the sealing flange 3 can cooperate to form a clamping effect. This clamping effect is used to fix the lifting shaft 222 to the connecting seat 2111 through the sealing flange 3, and at the same time, the replacement head 2112 can be installed. The installation is convenient and efficient.

[0031] To facilitate drainage, a drainage port 52 can be set on platform 5 during implementation, which can enable rapid drainage.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
