Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, and particularly relates to a hopper with an anti-adhesion inner wall. Background Technique

[0002] During the production process, the hopper body for conveying powder is prone to adhering powder on the inner hopper wall to form a caking layer. In the face of this problem, the open hopper body is easy to clean. However, in many production scenarios, an electric control valve is installed below the hopper body, and a feeding pipe is connected above the hopper body, making the hopper body in a sealed state, which makes it difficult to clean the inner hopper wall.

[0003] At present, external vibration devices including vibration motors can be used. By vibrating and knocking the outer wall, the powder on the inner wall can be made to fall off. However, there are problems such as high noise and easy deformation of the hopper wall. Therefore, it is considered to design a device that is convenient for cleaning the inner hopper wall in a sealed state and can avoid damaging the hopper body. In view of this, we propose a hopper with an anti-adhesion inner wall. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies mentioned in the above background technique and provide a hopper with an anti-adhesion inner wall.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An inner scraping component, which is rotatably installed inside the hopper body, includes a lining scraper that fits on the inner wall of the hopper body, and a toothed ring block and a bottom ring block are installed on the upper and lower sides of the lining scraper and the fixed rod;

[0008] A fixed rod is installed between the toothed ring block and the bottom ring block, and a brush roller for fitting on the inner wall of the hopper body is installed on the fixed rod.

[0009] Preferably, the hopper body is provided with a side convex block, and an air blowing pipe for communicating with the inside of the hopper body is installed on the side convex block.

[0010] Preferably, the hopper body is provided with a mounting groove and an annular groove for rotatably installing the toothed ring block;

[0011] A gear for meshing with the toothed ring block is installed in the mounting groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will combine the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model details the above technical solutions through the following embodiments:

[0026] A hopper with anti - adhesion inner wall, including a hopper body 1, further including:

[0027] An inner scraping component 2, rotatably installed inside the hopper body 1, as shown in Figure 1 , Figure 2 . The structure includes a lining scraper 23 attached to the inner wall of the hopper body 1. Tooth - ring blocks 21 and bottom - ring blocks 22 are installed on the upper and lower sides of the lining scraper 23 and the fixed rod 24. It should be noted that, combined with the structure shown in Figure 3 , Figure 4 , in this embodiment, the lining scraper 23 is provided with a hole - type conduction structure, aiming to reduce the contact area with the hopper wall. At the same time, the hole - type conduction structure can form a denser scraping edge structure, which can continuously scrape off the adhered powder during rotation, facilitating the improvement of the scraping effect.

[0028] In this embodiment, a fixed rod 24 is detachably installed between the tooth - ring block 21 and the bottom - ring block 22. A brush roller 25 for fitting against the inner wall of the hopper body 1 is fixedly installed on the fixed rod 24. The surface of the brush roller 25 has bristles, which can cooperate with the lining scraper 23 to better peel off the powder from the hopper wall. In addition, in this embodiment, a side convex block 11 is provided on the hopper body 1, and a blowing pipe 12 for communicating with the inside of the hopper body 1 is installed on the side convex block 11. It can be externally connected to a blower device to blow air into the hopper, which is also beneficial to avoiding the problem of the lining scraper 23 and the brush roller 25 re - adhering after scraping.

[0029] In this embodiment, an installation groove 102 and an annular embedding groove 101 for rotatably installing the tooth - ring block 21 are provided on the hopper body 1. A gear 3 for meshing with the tooth - ring block 21 is installed in the installation groove 102. A driving motor 6 coaxially connected to the gear 3 is installed on the hopper body 1. In order to prevent powder from entering this area, a sealing plate 4 is detachably installed above the hopper body 1 through bolts 5. The hopper body 1 is provided with threaded holes 103 for installing the bolts 5. After the sealing plate 4 is installed, the tooth - ring block 21 is in an embedded state, and together with the upper and lower sealing plates 4 and the hopper body 1, a sealing structure is formed to prevent powder from entering the meshing area.

[0030] The working principle of the hopper with anti - adhesion inner wall in this embodiment is as follows: This device is applicable to powders with a certain humidity. The powder is likely to adhere to the hopper wall. Through the rotating lining scraper 23 and brush roller 25, the powder can be continuously scraped off. At the same time, in order to prevent the powder from adhering to the lining scraper 23 and the brush roller 25 again, a blower device can be externally connected through the blowing pipe 12 to blow air into the hopper. Thus, it can effectively prevent a large amount of powder from adhering to the hopper wall, and this structure is stable and reliable.

[0031] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on what can be achieved by those of ordinary skill in the art. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
