Description

Technical Field

[0001] This utility model belongs to the technical field of mining filling systems, and more specifically, it relates to a high-lift, long-distance filling pump device. Background Technology

[0002] In mining backfilling systems, backfilling stations and goaf areas may be far apart due to the mine layout (such as deep wells, complex roadways, and large differences in elevation between the surface and underground). High-lift pumps provide powerful power to transport backfill slurry (such as tailings, waste rock slurry, paste, etc.) along pipelines to target areas tens of kilometers away, breaking through the transportation distance bottleneck of traditional low-lift pumps. Existing high-lift long-distance backfilling pumps generally consist of components such as a power system, pumping mechanism, transportation and pipeline system, control system, wear-resistant protective components, and auxiliary systems.

[0003] Existing application number: CN201420269825.9, this utility model proposes a filling industrial pump, including a cone valve housing, a cone valve assembly and a cone valve seat disposed within the cone valve housing. The cone valve seat is disposed at the feed inlet of the cone valve housing and fixed by a pressure plate. One end of the cone valve assembly is provided with a cylinder for pushing the cone valve assembly to move, and the other end of the cone valve assembly is used to cooperate with the cone valve seat. A wear-resistant layer is provided at the cooperation point between the cone valve assembly and the cone valve seat, and a first spring is also provided around the cone valve seat. This filling industrial pump structure can better ensure the coaxiality of the cone valve seat and the cone valve, reduce the requirements for the machining accuracy and assembly accuracy of related components, and at the same time, improve the sealing performance between the cone valve and the cone valve seat, improve the performance of the equipment, and extend the service life of the equipment.

[0004] Based on the above, in mining backfilling operations, backfill slurries such as tailings and waste rock slurries are prone to sedimentation and stratification in the hopper due to their own gravity and high concentration. This unevenness can lead to large fluctuations in the concentration of the slurry when it is sucked into the pump cylinder, which can cause abnormal suction of the pump cylinder, pipeline blockage, and fluctuations in the strength of the backfill. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-lift, long-distance filling pump device. This addresses the issue that in existing mining filling operations, filling slurries such as tailings and waste rock slurries tend to form a sedimentation stratification phenomenon in the hopper due to their own gravity and high concentration. This unevenness leads to large concentration fluctuations when the pumping cylinder draws in the slurry, resulting in abnormal pumping, pipeline blockage, and fluctuations in the strength of the filling material.

[0006] The purpose and effectiveness of this utility model's high-lift, long-distance filling pump device are achieved through the following specific technical means:

[0007] A high-lift, long-distance filling pump device includes a mounting plate, a hopper, a fixed plate, pumping cylinders, a drive motor, a second agitator, a fixed guide box, an anti-settling component, and an opening and cleaning component. The hopper is fixedly connected to the upper left side of the mounting plate. The fixed plate is fixedly connected inside the hopper. Two pumping cylinders are provided, and the two pumping cylinders are separately fixedly connected to the upper part of the mounting plate. The drive motor is fixedly connected to the front of the hopper. The top of the second agitator is rotatably connected to the inside of the fixed plate, and the bottom of the second agitator is rotatably connected to the bottom of the hopper. The fixed guide box is fixedly connected to the front of the hopper. The anti-settling component is disposed inside the hopper. The opening and cleaning component is disposed on the left side of the hopper.

[0008] Furthermore, the anti-settling component includes: a transmission worm and a transmission worm wheel; the transmission worm is coaxially and fixedly connected to the end of the drive motor shaft; the transmission worm wheel is rotatably connected inside the fixed plate, and the transmission worm wheel meshes with the transmission worm.

[0009] Furthermore, the anti-settling component also includes: a first stirring paddle and a first transmission gear; the first stirring paddle is coaxially and fixedly connected to the lower end of the transmission worm gear; the first transmission gear is coaxially and fixedly connected to the bottom of the first stirring paddle.

[0010] Furthermore, the anti-settling component also includes: a second transmission gear; the second transmission gear is rotatably connected to the bottom of the first stirring paddle, the second transmission gear is coaxially fixedly connected to the lower end of the second stirring paddle, and the second transmission gear meshes with the first transmission gear.

[0011] Furthermore, the opening cleaning assembly includes: a fixed frame and a sliding door; the fixed frame is fixedly connected to the left side of the hopper; the sliding door is inserted into the fixed frame.

[0012] Furthermore, the hole cleaning assembly also includes: a fixing hole, a fixing slider, a transmission screw, and an operating knob; the fixing hole is opened inside the front end of the sliding door; the fixing slider is slidably connected inside the fixing guide box; the transmission screw is rotatably connected inside the rear end of the fixing guide box, and the transmission screw is threadedly connected to the fixing slider; the operating knob is coaxially fixedly connected to the right end of the transmission screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, by driving the first and second stirring paddles to rotate in opposite directions by the drive motor, it can not only effectively break the sedimentation and stratification of the slurry in the hopper, so that the solid and liquid components are mixed evenly, avoiding abnormal suction of the pumping cylinder and blockage of the pipeline caused by uneven slurry concentration, but also gather the material at the corners of the hopper to the center, speed up the material flow efficiency, ensure the stability of the pumped slurry concentration, and thus improve the uniformity of the filling strength.

[0015] Secondly, when it is necessary to clean the material adhering to the inner wall of the hopper and the surface of the mixing paddle, simply turn the operating knob to open the sliding door, allowing tools to be inserted from the left side opening of the hopper for cleaning. This greatly reduces the difficulty of maintenance, avoids blockage of the feeding channel due to long-term accumulation of material, and reduces equipment downtime for cleaning.

[0016] This invention utilizes an anti-sedimentation component to disrupt the sedimentation and stratification of the slurry and promote the aggregation of materials at the edges, thereby achieving stable pumping concentration and improved uniformity of filling body strength. The sliding door facilitates the cleaning of materials adhering to the internal structure of the hopper, reducing downtime for cleaning and labor costs. Overall, it ensures the continuity and efficiency of filling operations and reduces labor maintenance costs. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a high-lift, long-distance filling pump device, including a mounting plate 1, a hopper 2, a fixing plate 201, a pumping cylinder 3, a drive motor 4, a second stirring paddle 701, a fixed guide box 10, and an anti-settling component; the hopper 2 is fixedly connected to the upper left side of the mounting plate 1; the fixing plate 201 is fixedly connected inside the hopper 2; two pumping cylinders 3 are provided, and the two pumping cylinders 3 are separately fixedly connected above the mounting plate 1; the drive motor 4 is fixedly connected to the front of the hopper 2; the top of the second stirring paddle 701 is rotatably connected to the inside of the fixing plate 201, and the bottom of the second stirring paddle 701 is rotatably connected to the bottom of the hopper 2; the fixed guide box 10 is fixedly connected to the front of the hopper 2; and the anti-settling component is disposed inside the hopper 2.

[0029] The anti-settling component includes a transmission worm gear 401 and a transmission worm wheel 5. The transmission worm gear 401 is coaxially fixedly connected to the end of the shaft of the drive motor 4. The transmission worm wheel 5 is rotatably connected inside the fixed plate 201 and meshes with the transmission worm gear 401.

[0030] The anti-sedimentation component also includes: a first stirring paddle 6 and a first transmission gear 601; the first stirring paddle 6 is coaxially fixedly connected to the lower end of the transmission worm gear 5; the first transmission gear 601 is coaxially fixedly connected to the bottom of the first stirring paddle 6.

[0031] The anti-settling component also includes a second transmission gear 7; the second transmission gear 7 is rotatably connected to the bottom of the first stirring paddle 6, the second transmission gear 7 is coaxially fixedly connected to the lower end of the second stirring paddle 701, and the second transmission gear 7 meshes with the first transmission gear 601.

[0032] The specific usage and function of this embodiment are as follows: During use, the drive motor 4 is started at regular intervals. The worm gear transmission mechanism, which is formed by the meshing of the transmission worm wheel 5 and the transmission worm 401, drives the first stirring paddle 6 to rotate. The first stirring paddle 6, through the gear transmission mechanism formed by the meshing of the second transmission gear 7 and the first transmission gear 601, drives the second stirring paddle 701 to rotate in the opposite direction to the first stirring paddle 6. This not only agitates the material that has been deposited at the bottom of the hopper 2 for a long time, breaking up the slurry sediment and ensuring the uniform concentration of the pumped material, but also allows the material at the corners of the hopper 2 to converge towards the middle part, so that it can be sucked in and pumped by the pumping cylinder 3 more quickly, thus accelerating the flow of material at the corners.

[0033] Example 2:

[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6As shown, it also includes an opening and cleaning component, which is located on the left side of the hopper 2.

[0035] The hole cleaning assembly includes a fixed frame 8 and a sliding door 9; the fixed frame 8 is fixedly connected to the left side of the hopper 2; and the sliding door 9 is inserted into the fixed frame 8.

[0036] The hole cleaning assembly also includes: a fixing hole 901, a fixing slider 11, a transmission screw 12, and an operating knob 1201; the fixing hole 901 is opened inside the front end of the sliding door 9; the fixing slider 11 is slidably connected inside the fixing guide box 10; the transmission screw 12 is rotatably connected inside the rear end of the fixing guide box 10, and the transmission screw 12 is threadedly connected to the fixing slider 11; the operating knob 1201 is coaxially fixedly connected to the right end of the transmission screw 12.

[0037] The specific usage and function of this embodiment: After prolonged use, some material may adhere to the surface of the hopper 2, the first stirring paddle 6, and the second stirring paddle 701, requiring cleaning. During cleaning, simply rotate the operating knob 1201. Guided by the fixed guide box 10, the fixed slider 11 is driven to slide to the right through the threaded transmission mechanism formed by the transmission screw 12 and the fixed slider 11, thereby disengaging the fixed slider 11 from the fixed hole 901. Then, pull the sliding door 9 forward to allow cleaning tools such as water pipes to be inserted from the left side of the hopper 2 to clean the first stirring paddle 6, the second stirring paddle 701, and the dead corners of the hopper 2, making the operation easier. After cleaning, insert the sliding door 9 back into the fixed frame 8, rotate the operating knob 1201 in the opposite direction, and insert the fixed slider 11 into the fixed hole 901 to complete the fixing of the sliding door 9.
