Hydrophobic hydraulic two-way plug door

Abstract

This utility model discloses a hydrophobic hydraulic bidirectional slide gate, belonging to the technical field of slide gates, and applied to the discharge port of a coal bunker. It includes a V-shaped mounting frame, on which a coal pipe is connected to the coal bunker discharge port. A gate is symmetrically slidably mounted inside the mounting frame, and a hydraulic cylinder is installed on the outer wall of the mounting frame to control the sliding of the gate along the inner wall of the frame. This hydrophobic hydraulic bidirectional slide gate, through the V-shaped mounting frame and gate, achieves two main benefits: first, the V-shaped slope guides the coal-water mixture smoothly into the lower coal discharge pipe, avoiding resource waste and on-site pollution; second, it reduces the accumulation of coal-water in the gap between the gate and the mounting frame, lowering the risk of component corrosion due to coal-water seepage and extending the equipment's service life.

Description

Technical Field

[0001] This utility model specifically relates to a hydrophobic hydraulic bidirectional slide gate, belonging to the technical field of slide gates. Background Technology

[0002] Horizontal slide gates are widely used in industrial production, especially in coal storage and transportation. With their simple structure and convenient operation, they play a crucial role in isolating and controlling the flow at the coal bunker outlet. Under normal operating conditions, they can precisely adjust the coal output by raising and lowering the slides, ensuring a stable production process.

[0003] However, in actual production, coal bunkers often face situations with excessively high moisture content. This may be due to moisture carried during coal mining, or the intrusion of moisture from the storage environment. When a coal-water mixture with excessive moisture content enters the horizontal gate area, problems arise. The planar structure of the horizontal gate cannot guide the flow of coal-water, and the coal-water easily accumulates in the gap between the gate and the frame, leading to overflow. Coal-water overflow not only wastes coal resources but also pollutes the production site, increases the difficulty of equipment cleaning and maintenance, and may even cause corrosion of the gate components due to coal-water penetration, affecting their service life and operational safety, and disrupting the normal production rhythm. Utility Model Content

[0004] The purpose of this utility model is to provide a hydrophobic hydraulic bidirectional slide gate to address the shortcomings of existing technologies.

[0005] A hydrophobic hydraulic bidirectional gate is used at the outlet of a coal bunker. It includes a V-shaped mounting frame with a coal pipe connected to the outlet of the coal bunker. A gate is symmetrically slidably installed inside the mounting frame, and a hydraulic cylinder is installed on the outer wall of the mounting frame to control the gate to slide along the inner wall of the mounting frame.

[0006] Furthermore, a sliding groove is provided on the inner wall of the mounting frame, and the gate is slidably connected inside the sliding groove.

[0007] Furthermore, the telescopic end of the hydraulic cylinder is connected to a hinge seat, and the end of the hinge seat away from the hydraulic cylinder is hinged to the gate.

[0008] Furthermore, a mounting base is installed on the gate plate, the mounting base including a lower support and an upper pressure seat, the hinge seat is hinged on the lower support, a positioning groove for the gate plate to be inserted is formed between the lower support and the upper pressure seat, and a locking bolt is provided on the upper pressure seat, the locking bolt being threadedly connected to the lower support.

[0009] Furthermore, the lower support is provided with a threaded blind hole, and the locking bolt is threadedly connected inside the threaded blind hole.

[0010] Furthermore, the lower support is provided with a groove communicating with the threaded blind hole, and a slanted push rod is slidably installed inside the groove. The gate plate is provided with a slot for inserting the slanted push rod.

[0011] Furthermore, a return spring is installed inside the slide groove. One end of the return spring is connected to the inner wall of the slide groove, and the other end of the return spring is connected to the inclined push rod. The initial elastic force of the return spring pulls the inclined push rod to move into the threaded blind hole.

[0012] Beneficial effects: 1. In this utility model, after the coal-water mixture in the coal bunker enters the installation frame through the coal pipe, the V-shaped inclined surface can actively guide the coal-water to flow into the lower coal drop pipe along a preset path, avoiding the accumulation of coal-water in the gaps caused by the planar structure of traditional horizontal insert doors.

[0013] 2. The present invention comprises a lower support, an upper pressure seat, and a locking bolt structure, which, together with an inclined push rod and a return spring, forms a dual fixing structure of bolt fastening and inclined push positioning, ensuring a stable connection between the gate and the mounting base and preventing loosening during subsequent sliding.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5As shown, a hydrophobic hydraulic bidirectional gate is used at the outlet of a coal bunker. It includes a V-shaped mounting frame 1, a coal pipe 2 connected to the outlet of the coal bunker on the mounting frame 1, a gate 4 symmetrically slidably installed inside the mounting frame 1, and a hydraulic cylinder 5 installed on the outer wall of the mounting frame 1 to control the gate 4 to slide along the inner wall of the mounting frame 1.

[0018] Specifically, during operation, the coal-water mixture in the coal bunker enters the V-shaped mounting frame 1 through the coal pipe 2. When it is necessary to open the discharge port or adjust the flow rate, the hydraulic cylinder 5 drives the gate plate 4 to slide along the inner wall of the mounting frame 1, so that the two gate plates 4 move away from each other, opening the channel, and the coal-water mixture is conveyed downward along the slope of the V-shaped mounting frame 1. When it is necessary to close the discharge port, the hydraulic cylinder 5 drives the gate plates 4 to move closer to each other, closing the channel. The V-shaped structure of the mounting frame 1 is key. After the coal-water mixture enters the mounting frame 1, it will flow along the V-shaped slope, avoiding accumulation at the bottom of the mounting frame 1 or in the gap between the gate plate 4 and the mounting frame 1.

[0019] As a technical optimization of this utility model, a sliding groove 3 is provided on the inner wall of the mounting frame 1, and the gate plate 4 is slidably connected inside the sliding groove 3.

[0020] Specifically, during operation, when the hydraulic cylinder 5 drives the gate plate 4 to slide, the gate plate 4 moves along the trajectory of the slide groove 3. The slide groove 3 provides a stable sliding guide for the gate plate 4, ensuring that the gate plate 4 always slides symmetrically along the preset direction of the inner wall of the mounting frame 1, and avoiding deviation or jamming when the gate plate 4 slides.

[0021] As a technical optimization of this utility model, the telescopic end of the hydraulic cylinder 5 is connected to a hinge seat 6, and the end of the hinge seat 6 away from the hydraulic cylinder 5 is hinged to the gate plate 4.

[0022] Specifically, during operation, when the extension end of the hydraulic cylinder 5 extends or retracts, the power is transmitted to the gate plate 4 through the hinge seat 6. Since the hinge seat 6 and the gate plate 4 are hinged, during the sliding process of the gate plate 4 along the slide groove 3, it can adapt to the angular deviation of the gate plate 4 caused by installation errors or slight changes in the sliding trajectory, and avoid the generation of rigid pulling force between the extension end of the hydraulic cylinder 5 and the gate plate 4.

[0023] As a technical optimization of this utility model, a mounting base 7 is installed on the gate plate 4. The mounting base 7 includes a lower support 71 and an upper pressure seat 72. The hinged seat 6 is hinged on the lower support 71. A positioning groove for the gate plate 4 to be inserted is formed between the lower support 71 and the upper pressure seat 72. A locking bolt 73 is provided on the upper pressure seat 72. The locking bolt 73 is threadedly connected to the lower support 71.

[0024] Specifically, during installation, the gate plate 4 is inserted into the positioning groove, and the locking bolt 73 is tightened so that the upper pressure seat 72 and the lower support 71 clamp the gate plate 4, thereby fixing the mounting seat 7 and the gate plate 4. During operation, the hydraulic cylinder 5 drives the gate plate 4 to slide through the hinge seat 6 and the mounting seat 7, and the mounting seat 7 stably transmits the power of the hinge seat 6 to the gate plate 4.

[0025] As a technical optimization of this utility model, a threaded blind hole is provided on the lower support 71, and the locking bolt 73 is threadedly connected inside the threaded blind hole.

[0026] Specifically, during installation, the locking bolt 73 is passed through the upper pressure seat 72 from above and screwed into the threaded blind hole of the lower support 71. As the locking bolt 73 is screwed in, the upper pressure seat 72 gradually presses the gate plate 4 downward until the gate plate 4 is firmly clamped in the positioning groove. During disassembly, the locking bolt 73 is screwed out in the opposite direction to loosen the upper pressure seat 72 and remove the gate plate 4.

[0027] As a technical optimization of this utility model, the lower support 71 is also provided with a sliding groove that communicates with the threaded blind hole. An inclined push rod 74 is slidably installed inside the sliding groove, and a slot for inserting the inclined push rod 74 is provided on the gate plate 4.

[0028] Specifically, when the locking bolt 73 is tightened, the lower end of the locking bolt 73 presses against the inclined surface of the inclined push rod 74, pushing the inclined push rod 74 to slide along the slide groove toward the gate plate 4. Finally, the inclined push rod 74 is inserted into the slot of the gate plate 4, forming an additional positioning support. When the locking bolt 73 is loosened, the inclined push rod 74 loses the pressing force and can slide in the opposite direction along the slide groove, disengage from the slot, and release the positioning.

[0029] As a technical optimization of this utility model, a return spring 75 is also installed inside the slide groove. One end of the return spring 75 is connected to the inner wall of the slide groove, and the other end of the return spring 75 is connected to the inclined push rod 74. The initial elastic force of the return spring 75 pulls the inclined push rod 74 to move into the threaded blind hole.

[0030] Specifically, when the locking bolt 73 is tightened, the locking bolt 73 overcomes the elastic force of the return spring 75 and pushes the inclined push rod 74 into the slot; when it is necessary to disassemble the gate plate 4, after loosening the locking bolt 73, the return spring 75, under its own elastic force, pulls the inclined push rod 74 to slide towards the threaded blind hole, so that the inclined push rod 74 automatically disengages from the slot of the gate plate 4 without the need to manually pry the inclined push rod 74.

[0031] Working principle: During the assembly of the gate body, the gate plate 4 and the hydraulic cylinder 5 are first connected and positioned by the mounting base 7: the gate plate 4 is inserted into the positioning groove formed by the lower support 71 and the upper pressure seat 72 of the mounting base 7, and then the locking bolt 73 on the upper pressure seat 72 is tightened so that the thread of the locking bolt 73 is screwed into the threaded blind hole of the lower support 71. During this process, the locking bolt 73 will squeeze the inclined push rod 74 in the slide groove of the lower support 71, overcome the initial elastic force of the return spring 75, and push the inclined push rod 74 to move towards the gate plate 4. Finally, the inclined push rod 74 is inserted into the slot on the gate plate 4, forming a double fixing structure of bolt fastening and inclined push positioning, ensuring that the gate plate 4 and the mounting base 7 are firmly connected and avoiding loosening during subsequent sliding. At the same time, the two sides of the gate plate 4 are embedded in the slide groove 3 of the inner wall of the mounting frame 1, providing guidance for the sliding of the gate plate 4 and ensuring that it moves smoothly along the inner wall of the mounting frame 1. When it is necessary to open the coal bunker outlet, hydraulic cylinder 5 is activated. The telescopic end of hydraulic cylinder 5 drives gate 4 to slide symmetrically along the slide groove 3 on the inner wall of mounting frame 1 through hinge seat 6. The two gates 4 move away from each other, gradually opening the channel inside mounting frame 1. Coal in the coal bunker enters mounting frame 1 through coal pipe 2, and then is conveyed downward to the coal drop pipe through the opening between the two gates 4. When it is necessary to close the outlet or adjust the flow rate, control the telescopic end of hydraulic cylinder 5 to retract, and pull the two gates 4 closer to each other along the slide groove 3 through hinge seat 6, narrowing or closing the channel to achieve flow rate adjustment or isolation function. When the moisture content in the coal bunker is too high and a coal-water mixture is formed, the coal-water mixture falls into the interior of the mounting frame 1 and flows along the inclined inner wall of the V-shaped structure, preventing it from accumulating at the bottom of the mounting frame 1 or in the gap between the gate 4 and the slide 3. At the same time, when the gate 4 slides along the slide 3, the guiding structure of the slide 3 can also reduce the retention of coal water at the edge of the gate. Finally, the coal-water mixture flows along the inclined surface of the V-shaped mounting frame 1 with the coal and flows into the lower coal drop pipe, fundamentally solving the problem of coal water overflow in traditional horizontal gates. If the gate plate 4 needs to be disassembled or replaced, simply loosen the locking bolt 73. At this time, the return spring 75 in the slide groove of the lower support 71 will pull the inclined push rod 74 into the threaded blind hole under its own elastic force, so that the inclined push rod 74 disengages from the slot on the gate plate 4 and releases the inclined push positioning. Then the gate plate 4 can be removed from the positioning slot of the lower support 71 and the upper pressure seat 72 to complete the disassembly. The operation is convenient and does not require damage to other structures of the gate, reducing the difficulty of maintenance.
