Description

Technical Field

[0001] This utility model belongs to the field of roller press technology, and more specifically, it relates to a roller press feed gate structure. Background Technology

[0002] In existing cement production equipment, roller presses are used to crush the raw materials needed for cement production. The gates of the roller press feeding devices are all flat plate structures. During actual operation, due to the segregation effect of material on both sides of the roller surface, the material cannot form a stable material pressure, affecting the working efficiency of the roller press. Therefore, there is a need for technical improvement.

[0003] Existing technology includes a technology entitled "Pneumatic Gate Valve for Roller Press Feeding" with publication (announcement) number "CN102364175B". This technology relates to an improvement in the structure of a pneumatic gate valve for roller press feeding. It includes a housing with a feed inlet, a gate valve mounted on the housing, and a drive cylinder for driving its movement. The gate valve is characterized by having at least two valve plates arranged vertically. The advantages of this invention are: 1) This invention has multiple valve plates. When material cutting is required, each valve plate moves. Since most of the material is blocked by the upper valve plate, even if the upper valve plate is jammed by material, the lower valve plate will close smoothly, achieving material cutting; 2) To further improve the compactness of the device and the material cutting effect, this invention arranges valve plate one and valve plate two vertically, with valve plate one and valve plate two moving in opposite directions. This ensures that the opening end of the lower valve plate two is blocked by the upper valve plate during material cutting, preventing it from being jammed by material. This allows for quick and convenient material cutting, ensuring the normal operation of the roller press equipment.

[0004] Existing technology includes a designation titled "A Feed Gate Valve Plate for a Roller Press," with publication number CN204805596U. This technology belongs to the field of cement production equipment and includes a right cylinder, a right gate valve plate, a right cylinder support, a discharge pipe, a left gate valve plate, a left cylinder support, and a left cylinder; it also includes a left support roller assembly and a right support roller assembly. The left support roller assembly is installed below the left gate valve plate and contacts its lower surface, located on the discharge pipes on both sides of the left gate valve plate, and includes two or more support rollers and two or more support roller shafts. The right support roller assembly is installed below the right gate valve plate and contacts its lower surface, located on the discharge pipes on both sides of the right gate valve plate, and includes two or more support rollers and two or more support roller shafts. This technology has the characteristics of reducing the impact of material gravity on the gate valve plate, increasing support for the valve plate, facilitating opening and closing, and reducing wear on the gate valve plate.

[0005] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a roller press feed gate structure that is simple in structure, can effectively eliminate the segregation effect of materials on both sides of the roller surface, ensure stable material pressure, and improve the working efficiency of the roller press, in order to address the shortcomings of the existing technology.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model is a feed gate structure for a roller press, including a gate, which includes a first side plate, a second side plate, and a middle plate. The first side plate is movably connected to one side of the middle plate, and the second side plate is movably connected to the other side of the middle plate. The middle plate is a fixed connection structure. The first side plate is connected to a first telescopic cylinder, and the second side plate is connected to a second telescopic cylinder.

[0009] The gate includes a first gate and a second gate, and the first gate and the second gate respectively include a first side plate, a second side plate, and an intermediate plate.

[0010] The roller press includes a first roller and a second roller.

[0011] The first and second gates are located above the first and second rollers, and the first and second gates have a V-shaped structure.

[0012] A first displacement detection component is provided below the first side plate of the first gate and below the first side plate of the second gate, and a second displacement detection component is provided below the second side plate of the first gate and below the second side plate of the second gate.

[0013] Each telescopic cylinder is connected to the hydraulic pressure supply system via pipelines.

[0014] One end of the pipeline is connected to the first port of a three-way solenoid valve, the second port of the three-way solenoid valve is connected to the first branch pipe, and the third port of the three-way solenoid valve is connected to the second branch pipe.

[0015] The first branch pipe is connected to the first chamber of a telescopic cylinder, and the second branch pipe is connected to the second chamber of a corresponding telescopic cylinder.

[0016] The first side plate is movably connected to one side of the middle plate via a hinge, and the second side plate is movably connected to the middle plate via a hinge.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The present invention relates to a roller press feed gate structure. The roller press includes a first roller and a second roller for pressing materials, and a gate is positioned above the middle of the first and second rollers. The improvement lies in the gate structure, which is no longer a single flat plate. The gate consists of two parts, each including a first side plate, a second side plate, and a middle plate. The middle plate is located in the middle and fixed to a support, thus fixing its position. One side of the middle plate is movably connected to the first side plate, and the other side is movably connected to the second side plate. This allows the first and second side plates to swing relative to the middle plate, with their positions corresponding to the two sides of the roller surface. The first side plate of each gate is hinged to one end of a first telescopic cylinder, and the second side plate of each gate is hinged to one end of a second telescopic cylinder. The other ends of the first and second telescopic cylinders are fixed to the support, thus fixing their positions. In this way, by controlling the extension and retraction of the first telescopic cylinder, the corresponding first side plate can be controlled to swing, and by controlling the extension and retraction of the second telescopic cylinder, the corresponding second side plate can be controlled to swing. This adjusts the gap between the two gate plates, thereby changing the segregation effect of the material on both sides of the roller surface and ensuring a stable material pressure. This effectively solves the technical problems existing in the prior art and improves the working efficiency of the roller press. Attached Figure Description

[0023] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0024] As attached Figure 1 Appendix Figure 2 As shown, this utility model is a feed gate structure for a roller press, including a gate, which comprises a first side plate 1, a second side plate 2, and a middle plate 3. The first side plate 1 is movably connected to one side of the middle plate 3, and the second side plate 2 is movably connected to the other side of the middle plate 3. The middle plate 3 is a fixed connection structure. The first side plate 1 is connected to a first telescopic hydraulic cylinder 4, and the second side plate 2 is connected to a second telescopic hydraulic cylinder 5. To address the shortcomings of the prior art, an improved technical solution is proposed. In this structural configuration, the roller press includes a first roller and a second roller for pressing materials, and a gate is positioned above the middle position of the first and second rollers. The improvement lies in the modification of the gate structure, eliminating the use of an integral flat plate gate structure. The gate consists of two parts, each including a first side plate 1, a second side plate 2, and a middle plate 3. The middle plate 3 is located in the middle and is fixed to the bracket, thus fixing its position. One side of the middle plate 3 is movably connected to the first side plate 1, and the other side is movably connected to the second side plate 2. This allows the first side plate 1 and the second side plate 2 to swing relative to the middle plate 3, with their positions corresponding to the two sides of the roller surface. The first side plate 1 of each gate is hinged to one end of the first telescopic cylinder 4, and the second side plate 2 of each gate is hinged to one end of the second telescopic cylinder 5. The other ends of the first telescopic cylinder 4 and the second telescopic cylinder 5 are fixed to the bracket, thus fixing their positions. In this way, by controlling the extension and retraction of the first telescopic cylinder 4, the corresponding first side plate 1 can be controlled to swing, and by controlling the extension and retraction of the second telescopic cylinder 5, the corresponding second side plate 2 can be controlled to swing, thereby adjusting the gap between the two gate plates and changing the segregation effect of the material on both sides of the roller surface, ensuring that the material forms a stable pressure. This effectively solves the technical problems existing in the prior art and improves the working efficiency of the roller press. The roller press feed gate structure described in this utility model has a simple structure, can effectively eliminate the segregation effect of the material on both sides of the roller surface, ensure that the material forms a stable pressure, and improve the working efficiency of the roller press.

[0025] The gate includes a first gate 6 and a second gate 7, each comprising a first side plate 1, a second side plate 2, and a middle plate 3. In this structure, the first gate 6 and the second gate 7 form a V-shape when viewed from the side. Both the first and second side plates of the first gate 6 and the second gate 7 are capable of swing control, altering the lateral clearance.

[0026] The roller press includes a first roller 8 and a second roller 9. A first gate plate 6 and a second gate plate 7 are located above and between the first roller 8 and the second roller 9, and the first gate plate 6 and the second gate plate 7 have a V-shaped structure. In this structure, the first side plate 1 of each gate plate is controlled to swing by a first telescopic hydraulic cylinder 4, and the second side plate 2 of each gate plate is controlled to swing by a second telescopic hydraulic cylinder 5, thereby effectively changing the gap between the two sides of the roller surface and solving the existing problems.

[0027] A first displacement detection component 10 is installed below the side of the first side plate 1 of the first gate 6 and below the side of the first side plate 1 of the second gate 7. A second displacement detection component 11 is installed below the side of the second side plate 2 of the first gate 6 and below the side of the second side plate 2 of the second gate 7. In this structure, each displacement detection device detects the gap between the corresponding sides of the gate, and the detection signal is transmitted to the central control unit. The central control unit issues a command to control the hydraulic system to accurately adjust the gap distance between the two sides of the gate, so as to keep the material pressure of the feeding device always controlled within the required range.

[0028] Each telescopic cylinder is connected to a hydraulic supply system (hydraulic system) via pipeline 12. The hydraulic supply system includes an oil tank and an oil pump, which reliably supplies hydraulic oil at the corresponding pressure. Thus, hydraulic oil can be supplied to the corresponding telescopic cylinder through pipeline 12.

[0029] One end of the pipeline 12 is connected to the first port of a three-way solenoid valve, the second port of the three-way solenoid valve is connected to the first branch pipe 13, and the third port of the three-way solenoid valve is connected to the second branch pipe 14. The first branch pipe 13 is connected to the first chamber 15 of a telescopic cylinder 5, and the second branch pipe 14 is connected to the second chamber 16 of a corresponding telescopic cylinder 5. The first side plate 1 is hinged to one side of the intermediate plate 3, and the second side plate 2 is hinged to the intermediate plate 3. With the above structure, the second and third ports of the three-way solenoid valve can be controlled to open and close, allowing oil to be supplied to either the first branch pipe 14 or the second branch pipe 15. When the first branch pipe 13 supplies oil, the first chamber 15 receives oil, the second chamber 16 discharges oil, and the second branch pipe 15 returns oil. The piston of the first telescopic cylinder 4 moves, causing the telescopic rod to extend, reducing the gap between the two gate sides. When the second branch pipe 14 supplies oil, the second chamber 16 receives oil, the first chamber 15 discharges oil, and the first branch pipe 14 returns oil. The piston of the first telescopic cylinder 4 moves, causing the telescopic rod to retract, increasing the gap between the two gate sides. The control principle and process of the second telescopic cylinder are the same as those of the first telescopic cylinder, thus achieving reliable control.

[0030] The roller press feed gate structure of this utility model includes a first roller and a second roller for pressing materials. A gate is positioned above the middle position of the first and second rollers. The improvement lies in the gate structure, which is no longer a single flat plate. The gate consists of two parts, each including a first side plate 1, a second side plate 2, and a middle plate 3. The middle plate 3 is located in the middle and fixed to a support, thus fixing its position. One side of the middle plate 3 is movably connected to the first side plate 1, and the other side is movably connected to the second side plate 2. This allows the first side plate 1 and the second side plate 2 to swing relative to the middle plate 3, with their positions corresponding to the two sides of the roller surface. The first side plate 1 of each gate is hinged to one end of the first telescopic cylinder 4, and the second side plate 2 of each gate is hinged to one end 5 of the second telescopic cylinder. The other ends of the first telescopic cylinder 4 and the second telescopic cylinder 5 are respectively fixed to the bracket, thus fixing the positions of the first telescopic cylinder 4 and the second telescopic cylinder 5. In this way, by controlling the extension and retraction of the first telescopic cylinder 4, the corresponding first side plate 1 can be controlled to swing; by controlling the extension and retraction of the second telescopic cylinder 5, the corresponding second side plate 2 can be controlled to swing. This adjusts the gap between the two gates, changing the segregation effect of the material on both sides of the roller surface and ensuring a stable material pressure. This effectively solves the technical problems existing in the prior art and improves the working efficiency of the roller press.
