Description

Technical Field

[0001] This utility model relates to a discharge valve, and in particular to an anti-static discharge valve. Background Technology

[0002] The discharge valve is a device that uses the rotation of blades driven by the main shaft to allow external materials to enter the container from the inlet and exit from the outlet. In other words, the function of the discharge valve is to allow a specified amount of material to enter the container or exit from the container.

[0003] In conventional materials, the blades and the inner wall of the valve body have a transition fit. However, for materials that do not require static electricity, the material falls onto the top of the blade. As the blade rotates, the material is squeezed between the top of the blade and the inner wall of the valve body. Since both the inner wall of the valve body and the blade are metal, this can easily generate static electricity or sparks.

[0004] In summary, how to achieve the static discharge requirement of the unloading valve has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to meet the requirement of static electricity discharge in the unloading valve;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is an antistatic unloading valve, comprising: a valve body; a main shaft, which is rotatably disposed within the valve body, and having a plurality of blades extending radially outward from its outer peripheral wall, wherein there is a gap between the top of the blades and the inner wall of the valve body; an antistatic plate, which is disposed on the rotating surface of the blades, with its top protruding from the top of the blades and contacting the inner wall of the valve body; and a pressure strip assembly, which fixes the antistatic plate on the rotating surface of the blades.

[0008] Furthermore, the antistatic board has a rectangular structure, and the material of the antistatic board is polytetrafluoroethylene or rubber.

[0009] Furthermore, the pressure strip assembly includes: a horizontal pressure strip disposed on one side of the top of the antistatic plate; a vertical pressure strip disposed on both sides of the antistatic plate; and a locking member that passes through the horizontal or vertical pressure strip, the antistatic plate, and the blade in sequence.

[0010] Furthermore, the horizontal and vertical pressure strips are made of Q234B or 304 stainless steel.

[0011] Furthermore, the horizontal and vertical pressure strips have countersunk holes on their surfaces, and the head of the locking member is located inside the countersunk holes.

[0012] The beneficial effects of this utility model are as follows: This utility model is an anti-static unloading valve. The pressure bar assembly fixes the anti-static plate on the blade. The top of the anti-static plate is in contact with the inner wall of the valve body. When the material falls into the top of the anti-static plate, even if the material is squeezed, the anti-static plate will not generate static electricity, thus realizing the anti-static function of the unloading valve. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Figure 1 This is a schematic diagram of the structure of this utility model;

[0015] Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] To achieve the anti-static function of the unloading valve, the following embodiments are disclosed in this solution;

[0018] This embodiment is an anti-static unloading valve. See [link / reference] Figure 1 In the diagram, the top of valve body 1 is the inlet 11, and the bottom is the outlet 12; the main shaft 2 runs horizontally through valve body 1, and the portion of the main shaft 2 located inside valve body 1 extends radially outward with multiple blades 3; see also Figure 2 The blade 3 rotates with the main shaft 2. A gap 13 exists between the top of the blade 3 and the inner wall of the valve body 1, preventing friction between the material falling onto the top of the blade 3 and the inner wall of the valve body 1. An antistatic plate 4 is disposed on the rotating surface of the blade 3, for example... Figure 2 In the middle, the main shaft 2 rotates clockwise, and the right side of the blade 3 at the 12 o'clock position is the windward side. An antistatic plate 4 is provided on the right side of the blade 3, and a pressure strip assembly is provided on the right side of the antistatic plate 4. The pressure strip assembly fixes the antistatic plate 4 to the blade 3. The top of the antistatic plate 4 is in contact with the inner wall of the valve body 1. When the material falls into the top of the antistatic plate 4, the antistatic plate will not generate static electricity even if the material is squeezed. The antistatic plate 4 is made of polytetrafluoroethylene or rubber.

[0019] The pressure strip assembly includes: a horizontal pressure strip 5 and two vertical pressure strips 6. The horizontal pressure strip 5 is located on one side of the top of the antistatic plate 4, and the locking member 7 passes through the horizontal pressure strip 5, the antistatic plate 4, and connects to the blade 3. The vertical pressure strips 6 are located on the left and right sides of the antistatic plate 4 (i.e., perpendicular to the paper surface), and the locking member 7 passes through the vertical pressure strips 6, the antistatic plate 4, and connects to the blade 3. In this way, the antistatic plate 4 and the blade 3 are fixed by the cooperation of the horizontal pressure strip 5, the two vertical pressure strips 6, and the corresponding locking member 7. The horizontal pressure strip 5 and the two vertical pressure strips 6 are made of Q234B or 304 stainless steel.

[0020] To ensure the flatness of the surfaces of the horizontal pressure strip and the two vertical pressure strips and to prevent materials from being trapped in the protrusions, countersunk holes are provided on the surfaces of the horizontal pressure strip 5 and the vertical pressure strip 6. The head of the locking member 7 is located in the countersunk hole, ensuring that the surfaces of the horizontal pressure strip 5, the two vertical pressure strips 6 and the locking member 7 are flat after connection.

[0021] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
