Description

Technical Field

[0001] This application relates to the technical field of hoists, and in particular to a hoist with an automatic cleaning function. Background Technology

[0002] Elevators are used for the vertical transport of granular and powdery materials in the food, feed, and chemical industries. They are characterized by their novel design, safe and reliable operation, simple structure, complete functions, good sealing, and low noise. In particular, their high output, low backflow, low failure rate, and long service life ensure high efficiency. They are suitable for both powder and granular materials and are equipped with explosion-proof covers and pressure balancing devices. Due to the variable lifting height and output, the process layout is flexible, enhancing their adaptability. Therefore, they are currently an ideal lifting equipment.

[0003] Existing elevators are prone to material residue at the bottom, which is difficult to clean and requires manual cleaning, which is time-consuming, labor-intensive, and increases costs. If these residues are not cleaned up in time, they will accumulate and deteriorate over time, affecting the raw materials and causing a decline in product quality. Utility Model Content

The vertical pipe is connected to the middle of the bottom end of the arc-shaped base plate. The tail plug is fixed to the bottom end of the vertical pipe. The lifting rod is movably disposed inside the vertical pipe and passes through the tail plug. The electric push rod is disposed at the bottom end of the lifting rod and is used to drive the lifting rod to rise and fall. An air passage is opened in the middle of the lifting rod, and an air inlet pipe is connected to the side of the lifting rod near the bottom end. The top cover is fixed to the top end of the lifting rod. The lifting rod has a plurality of air outlets evenly opened along the radial direction. The air outlets are located at the bottom of the top cover. The top cover can cover the vertical pipe. The vacuum cleaner is connected to the side wall of the vertical pipe.

[0006] Preferably, the top cover includes an arc-shaped cover body, a rubber pad, and a base plate, with the rubber pad disposed between the arc-shaped cover body and the base plate.

[0007] By adopting the above technical solution, the curved top cover with a smooth surface can reduce material residue on the curved cover; the rubber gasket forms a seal between the rubber gasket and the vertical pipe, which is easy to manufacture and maintain.

[0008] A bracket is fixed to the bottom of the arc-shaped base plate, and the electric push rod is fixed to the bracket.

[0009] A sealing element is provided between the middle of the tail plug and the lifting rod.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] This application discloses a lifting machine with an automatic cleaning function, referring to... Figure 1-3The system includes a bucket elevator body 1, which is a vertical bucket elevator. The bottom of the elevator body 1 is an arc-shaped base plate 11. A cleaning mechanism 2 is installed at the bottom of the arc-shaped base plate 11. The cleaning mechanism 2 includes a vertical pipe 21, a tail plug 22, a lifting rod 23, an electric push rod 24, a top cover 25, and a vacuum cleaner (not shown in the figure). The vertical pipe 21 is connected to the middle of the bottom end of the arc-shaped base plate 11. The tail plug 22 is fixed to the bottom end of the vertical pipe 21. The lifting rod 23 is movably installed inside the vertical pipe 21 and passes through the tail plug 22. The electric push rod 24 is installed at the bottom end of the lifting rod 23 and is used to drive the lifting rod 23 to rise and fall. In order to improve... The sealing effect between the lifting rod 23 and the tail plug 22 is as follows: a sealing element is provided between the middle of the tail plug 22 and the lifting rod 23; a bracket 12 is fixed at the bottom of the arc-shaped base plate 11; an electric push rod 24 is fixed on the bracket 12; an air passage is opened in the middle of the lifting rod 23; an air inlet pipe 231 is connected to the side of the lifting rod 23 near the bottom; compressed air is connected to the air inlet pipe 231; a top cover 25 is fixed to the top of the lifting rod 23; several air outlets 232 are evenly opened along the radial direction of the lifting rod 23; the air outlets 232 are located at the bottom of the top cover 25; the top cover 25 can cover the vertical pipe 21; the vacuum cleaner is connected to the side wall of the vertical pipe 21.

[0019] Reference Figure 4 The top cover 25 includes an arc-shaped cover body 251, a rubber pad 252 and a base plate 253, with the rubber pad 252 disposed between the arc-shaped cover body and the base plate 253.

[0020] By setting an arc-shaped top cover 25 with a smooth surface, material residue on the arc-shaped cover 251 can be reduced; by setting a rubber pad 252, a seal is formed between the rubber pad 252 and the vertical pipe 21, which is easy to manufacture and maintain.

[0021] Reference Figure 2-3 In order to suck away as much material as possible from the vertical pipe 21, the top surface of the tail plug 22 is inclined, and the side of the vertical pipe 21 is inclined with a discharge pipe 211. The connection between the discharge pipe 211 and the vertical pipe 21 is located next to the lower part of the inclined surface, and the discharge pipe 211 is connected to the vacuum cleaner.

[0022] The implementation principle of a lifting machine with automatic cleaning function in this application embodiment is as follows: With the cleaning mechanism 2 in place, after the material is lifted, the electric push rod 24 pushes the lifting rod 23 upward, creating a gap between the top cover 25 and the vertical pipe 21. At this time, the vacuum cleaner works and can suck away the material in the vertical pipe 21. At the same time, compressed air is intermittently introduced through the air inlet pipe 231. The compressed air is blown out from the air outlet 232, blowing up the material left in the arc-shaped bottom plate 11. As the material is blown up and falls, it will gather at the opening of the vertical pipe 21 under its own gravity, so that it can be sucked away by negative pressure. After several blowing actions, the material left in the arc-shaped bottom plate 11 can be completely sucked away, thus preventing the material from accumulating and deteriorating for a long time.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
