[0027] Embodiment 1

[0028] This embodiment provides a non-detachable gate plate, including:

[0029] A frame, with an upper locking plate 1 and a lower locking plate 7 respectively provided at its opposite ends. The upper locking plate 1 is connected to the frame by bolts. On the side of the upper locking plate 1 facing the lower locking plate 7, there is an upper clamping structure 8. For example, referring to Figure 1-2 , the cross-section of the upper locking plate 1 is an inverted concave structure. The upper locking plate 1 is installed at the top of the frame by bolts. The front and rear ends of the upper locking plate 1 protrude from the frame. At the bottom ends of the protruding parts at the front and rear ends of the upper locking plate 1, there are fixed upper clamping structures 8. The upper clamping structure 8 can be a straight triangular prism structure, and the inclined surface of the upper clamping structure 8 faces the frame, that is, the inclined surface of the upper clamping structure 8 gradually moves away from the frame from the top to the bottom, thus forming a clamping structure.

[0030] A deflector plate 2, whose first end is clamped between the upper clamping structure 8 and the frame, and the second end of the deflector plate 2 abuts against the lower locking plate 7. For example, referring to Figure 1-2 , there is one deflector plate 2 on each of the front and rear sides of the frame. The front and rear deflector plates 2 correspond to the front and rear upper clamping structures 8 respectively. An upper limiting structure adapted to the upper clamping structure 8 is formed at the top end of the deflector plate 2. The upper limiting structure can be a straight triangular prism. When the upper limiting structure is clamped between the upper clamping structure 8 and the frame, the inclined surface of the upper limiting structure fits with the inclined surface of the upper clamping structure 8, so that the top end of the deflector plate 2 is clamped and fixed. Also, since the bottom end of the deflector plate 2 abuts against the lower locking plate 7, the two deflector plates 2 are clamped and fixed on the front and rear sides of the frame.

[0031] Based on the above structure, when the non-detachable gate plate provided in this embodiment is in use, the deflector plate 2 directly contacts the material. If the surface of the deflector plate 2 is damaged and needs to be maintained or replaced, by removing the upper locking plate 1, the upper clamping structure 8 is separated from the deflector plate 2, and the deflector plate 2 can be quickly removed without disassembling the entire gate plate, and the operation is simple and convenient.

[0032] In this embodiment, the lower locking plate 7 can also be connected to the frame by bolts. In this way, the lower locking plate 7 can be quickly removed. When it is not convenient to remove the upper locking plate 1, by removing the lower locking plate 7, the lower locking plate 7 is separated from the second end of the deflector plate 2, and the deflector plate 2 can also be quickly removed.

[0033] To improve the stability of the deflector 2, the lower locking plate 7 is provided with a lower clamping structure 5 on the side facing the upper locking plate 1, and the second end of the deflector 2 is clamped between the lower clamping structure 5 and the frame. The lower clamping structure 5 can be symmetrical with the upper clamping structure 8. For example, see Figure 1-2 , the cross-section of the lower locking plate 7 is a concave structure, both the front and rear ends of the lower locking plate 7 protrude from the frame, and the top of the protruding parts at the front and rear ends of the lower locking plate 7 are fixed with the lower clamping structure 5. The lower clamping structure 5 can be a straight triangular prism structure, and the inclined surface of the lower clamping structure 5 faces the frame, that is, the inclined surface of the lower clamping structure 5 gradually moves away from the frame from the bottom end to the top end, thus forming a clamping structure. Correspondingly, the bottom end of the deflector 2 is provided with a lower limiting structure, and the lower limiting structure can be symmetrical with the upper limiting structure. When the lower limiting structure is clamped between the lower clamping structure 5 and the frame, the inclined surface of the lower limiting structure fits with the inclined surface of the lower clamping structure 5, so that the bottom end of the deflector 2 is clamped and fixed.

[0034] In this embodiment, the frame can include a top plate 4, a connecting pipe 6, and two vertical plates 3. The two ends of the vertical plate 3 are respectively fixed to the top plate 4 and the connecting pipe 6. For example, see Figure 1 , the two vertical plates 3 are arranged vertically, the connecting pipe 6 and the top plate 4 are arranged horizontally, the top end of the vertical plate 3 is fixed to the top plate 4, and the bottom end of the vertical plate 3 is fixed to the connecting pipe 6, jointly forming the overall structure of the frame.

[0035] Among them, the deflector 2 is parallel to the vertical plate 3. The top end of the deflector 2 is clamped between the upper clamping structure 8 and the vertical plate 3, and the bottom end of the deflector 2 is clamped between the lower clamping structure 5 and the vertical plate 3.

[0036] The upper locking plate 1 is parallel to the top plate 4, the upper locking plate 1 is located above the top plate 4, and the upper locking plate 1 is connected to the top plate 4 by bolts.

[0037] The lower locking plate 7 is parallel to the top plate 4, the lower locking plate 7 is located below the connecting pipe 6, and the lower locking plate 7 is connected to the connecting pipe 6 by bolts.

[0038] The top plate 4 and the vertical plate 3 can both be steel plates, and the connecting pipe 6 can be a steel pipe. The two ends of the vertical plate 3 are respectively welded and fixed to the top plate 4 and the connecting pipe 6. The deflector 2 can also be a steel plate. The structure has high stability and strength.

[0039] Embodiment 2

[0040] This embodiment provides a three-way gate valve, including the detachable-free gate plate in Embodiment 1. Specifically, as Figure 3-4 shown, the three-way gate valve includes a housing 9, a rotating shaft 15, a bearing seat 10, an electric push rod 11, a rotating arm 12, a base 14, and a detachable-free gate plate.

[0041] The bearing housing 10 and the base 14 are both arranged on the side wall of the housing 9. The rotating shaft 15 penetrates through the housing 9, and the rotating shaft 15 is rotatably arranged in the bearing housing 10. One end of the detachable-free gate is fixed to the rotating shaft 15.

[0042] One end of the electric push rod 11 is hinged to the base 14, the other end of the electric push rod 11 is hinged to the rotating arm 12, and the end of the rotating arm 12 far from the electric push rod 11 is fixedly connected to the rotating shaft 15.

[0043] In this way, by the telescopic movement of the electric push rod 11, the rotating arm 12 can be driven to swing around the rotating shaft 15, and then the rotating shaft 15 can be driven to rotate, and further the detachable-free gate can be driven to swing around the rotating shaft 15. For example, referring to Figure 3 , when the detachable-free gate swings from the leftmost side to the rightmost side in the clockwise direction, the flow path in the three-way valve is changed. And during the material flow process, it mainly contacts with the guide plate 2. After long-term use, the guide plate 2 may be damaged. The detachable-free gate can quickly disassemble the guide plate 2, effectively solving the above problems.

[0044] In this embodiment, when installing the detachable-free gate and the rotating shaft 15, the rotating shaft 15 can be sleeved in the connecting pipe 6. The rotating shaft 15 is provided with screw holes corresponding to the connecting pipe 6, and the screw holes on the connecting pipe 6 correspond to the screw holes of the lower lock plate 7. In this way, by sequentially passing bolts through the screw holes of the lower lock plate 7, the connecting pipe 6, and the rotating shaft 15, the lower lock plate 7, the connecting pipe 6, and the rotating shaft 15 can be fixedly connected, and the operation is simple and convenient.

[0045] In this embodiment, the housing 9 may be provided with an observation window 13 to facilitate observing the internal situation.

[0046] The mechanisms, components, and parts not described in detail in the present utility model are existing structures that already exist in the prior art and can be directly purchased from the market.
