[0002] Paste filling technology refers to the process of converting solid waste such as coal gangue, fly ash, and soil into a paste-like slurry with no critical flow and dehydration after coal seam mining and before roof collapse. The left and right conveying cylinders of the paste filling pump continuously alternate their suction and conveying strokes, so that the material in the cylinder is continuously transported to the conveying pipeline through the swing valve. Then, the material is transported to the working face through the conveying pipeline to fill part of the goaf space. The green mining technology of timely filling the goaf through filling strips establishes alternating filling strips to support the overlying strata.

[0003] However, the delivery cylinder and internal piston of the paste filling pump are in a reciprocating cycle for a long time. During this process, a lot of heat is generated due to friction and gas compression. If the heat is not cooled in time, it will lead to problems such as overheating and damage to the equipment.

By placing a cooling jacket connected to the cooling pump on the outside of the conveying cylinder, the conveying cylinder is cooled by the cooling water flowing inside the cooling jacket cavity. At the same time, the cooling pump can slide left and right through the slide rail and slider, which effectively reduces the space occupied by the cooling pump.

[0022] 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.

[0023] Please see Figures 1-7As shown, a cooling device for a paste filling pump in a coal mine includes a mounting frame 1. A support structure 4 is mounted on the mounting frame 1. The support structure 4 includes a slide rail 401. Two slide rails 401 are fixedly connected to the mounting frame 1. Slider blocks 402 are slidably connected to the slide rails 401. The top ends of the two sliders 402 are fixedly connected to the same support plate 403. A cooling structure 3 is mounted on the support plate 403. The cooling structure 3 includes a cooling pump 301. The cooling pump 301 is mounted on the support plate 403. A filling pump body 2 is mounted on the mounting frame 1. The filling pump body 2 includes two conveying cylinders 201. The conveying cylinders 201 are mounted on the mounting frame 1. A first cooling sleeve 304 and a second cooling sleeve 305 are respectively fitted onto the two conveying cylinders 201. The first cooling sleeve 304... A water inlet 303 is provided, and a flexible hose 302 is installed between the cooling pump 301 and the water inlet 303. A limiting structure 5 is installed on the support plate 403. By placing a cooling jacket connected to the cooling pump 301 outside the conveying cylinder 201, the cooling water flowing inside the cooling jacket cools the conveying cylinder 201. When the cooling pump 301 needs to be operated, the support plate 403 is pulled outward, and the support plate 403 drives the slider 402 to slide outward on the slide rail 401, thereby sliding the cooling pump 301 out from the bottom of the conveying cylinder 201 for easy operation. After the operation is completed, the support plate 403 is pushed downward to the conveying cylinder 201, and the slider 402 slides to make the support plate 403 drive the cooling pump 301 to slide under the conveying cylinder 201, thereby reducing the space occupied by the cooling pump 301.

[0024] As a technical optimization of this utility model, the slide rail 401 is perpendicular to the mounting bracket 1, and the slider 402 has a trapezoidal structure; the trapezoidal structure of the slider 402 makes the sliding of the slider 402 more stable.

[0025] As a technical optimization of this utility model, the limiting structure 5 includes a locking rod 501. Two locking rods 501 are slidably connected to the support plate 403. Multiple limiting holes 503 are equally spaced on both slide rails 401. The locking rods 501 engage with the limiting holes 503. The ends of the locking rods 501 are conical. A connecting rod 502 is fixedly connected between the two locking rods 501. A baffle 505 is fixedly connected to the locking rods 501. A spring 504 is fixedly connected between the baffle 505 and the support plate 403. The limiting structure 5 limits the slider 402, fixes the position of the slider 402 and the cooling pump 301, and prevents the slider 402 from slipping off the slide rail 401.

[0026] As a technical optimization of this utility model, a connecting pipe 306 is fixedly connected between the first cooling jacket 304 and the second cooling jacket 305, and a water outlet 307 is provided on the second cooling jacket 305; an external water source is connected to the connection port of the cooling pump 301, and after the water source is processed by the cooling pump 301, it enters the cavity of the first cooling jacket 304 through the hose 302 connected to the outlet of the cooling pump 301. The cooling water circulates inside the first cooling jacket 304, and then enters the cavity of the second cooling jacket 305 through the connecting pipe 306, and finally exits from the water outlet 307 on the second cooling jacket 305, thereby circulating the cooling water inside the two cooling jackets, thereby cooling the delivery cylinder 201 and protecting the paste filling pump body 2.

[0027] As a technical optimization of this utility model, rubber plugs 6 are installed at both ends of the first cooling sleeve 304 and the second cooling sleeve 305. The rubber plugs 6 have an "L" shaped structure; they play a sealing role for the first cooling sleeve 304 and the second cooling sleeve 305 to prevent cooling water from flowing out.

[0028] As a technical optimization of this utility model, a piston 205 is slidably connected inside the conveying cylinder 201, and a material cylinder 202 is fixedly connected to the end of the conveying cylinder 201. A swing valve 204 is installed on the side of the material cylinder 202 facing the conveying cylinder 201, and a conveying pipe 203 is installed on the side of the material cylinder 202 away from the conveying cylinder 201. The conveying pipe 203 is fixedly connected to the swing valve 204. The material is conveyed to the working surface by the operation of the paste filling pump, which improves the working efficiency.

[0029] In use, the present invention first activates the switch of the paste filling pump body 2. When the swing valve 204 is pushed by the swing cylinder, the conveying pipe 203 is aligned with one of the conveying cylinders 201. At this time, the other conveying cylinder 201 is connected to the material cylinder 202. The pressure oil from the oil pump enters the rodless chamber of the conveying cylinder 201 opposite to the conveying pipe 203, and the internal piston 205 extends to generate pumping operation. The material in the conveying cylinder 201 is pumped into the conveying pipe 203 through the swing valve 204. At the same time, the hydraulic pressure in the conveying cylinder 201 enters the other conveying cylinder 201 through the pipe connecting the two conveying cylinders 201, and pushes the internal piston 205 to retract and generate suction. The material in the feed cylinder 202 is sucked into the conveying cylinder 201. Then, when the piston 205 pushes the feed cylinder 202 to its end, the swing valve 204 drives the conveying pipe 203 to swing relative to the other conveying cylinder 201. Under the action of the piston 205, the material is pumped into the conveying pipe 203. The two conveying cylinders 201 continuously alternate to complete their respective suction and conveying strokes, thus completing the pumping operation. Because the pistons 205 in the two conveying cylinders 201 are in a reciprocating motion state for a long time, the temperature inside the conveying cylinders 201 rises. At this time, an external water source is connected to the connection port of the cooling pump 301. The water source is processed by the cooling pump 301 and then connected to the discharge port of the cooling pump 301. The hose 302 enters the cavity of the first cooling jacket 304, where cooling water circulates. It then flows through the connecting pipe 306 into the cavity of the second cooling jacket 305, finally exiting through the outlet 307 on the second cooling jacket 305. This circulates the cooling water within both cooling jackets, cooling the delivery cylinder 201 and protecting the paste filling pump body 2. When the cooling pump 301 needs to be installed or removed, the connecting rod 502 is pulled upwards. The connecting rod 502 causes the locking rods 501 connected at both ends to slide out of the limiting hole 503. Simultaneously, the locking rods 501 cause the baffle 505 to move upwards, and the baffle 505 retracts against the spring 504. The slider 402 is released by retracting the slide rail 401, and then the connecting rod 502 is dragged outward. The connecting rod 502 drives the slider 402 to slide outward on the slide rail 401 through the support plate 403. When the coolant pump 301 moves to the appropriate position, the connecting rod 502 is released, the spring 504 returns to its original position, and the locking rod 501 slides into the adjacent limiting hole 503 until the locking rod 501 engages in the limiting hole 503, so that the slider 402 can no longer slide left or right, thereby fixing the position of the coolant pump 301, which is convenient for maintenance of the coolant pump 301. Moreover, the cooperation between the slide rail 401 and the slider 402 makes the coolant pump 301 flexible to use and reduces the space occupied by the coolant pump 301.
