Abstract
Description
Technical Field
[0001] This utility model relates to a device for cleaning and dewatering sludge in mine water tanks, belonging to the field of mine water tank sludge cleaning equipment. Background Technology
[0002] Mine water sump is a facility for storing circulating water in underground mines, typically several hundred meters in length. It is primarily used to store mine-rushing water and mine drainage. Over long periods of use, a large amount of silt accumulates at the bottom of the sump. To ensure its water storage capacity, the silt needs to be cleaned regularly. Traditionally, the silt is excavated and hauled into the main roadway or abandoned roadway for settling and drying. The dried sludge is then transported to the surface via a hoisting system. This method is labor-intensive and inefficient. To reduce labor intensity and improve efficiency, current mine water sump cleaning often uses a mixing device to agitate the settled silt into a slurry. This slurry is then pumped into a dewatering device for dewatering before being loaded onto trucks and transported away.
[0003] Existing sludge dewatering devices are ineffective. For example, Chinese utility model patent CN222593667U discloses a rapid dewatering device for fine sludge in coal mines. This prior art utilizes vacuum negative pressure to extract moisture from coal sludge, thus achieving automatic dewatering. However, because the pressure generated by vacuum negative pressure is relatively low, the dewatering effect is poor. This results in the transported sludge still containing a significant amount of moisture, leading to high transportation costs. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a mine water tank sludge cleaning and dewatering device with better dewatering effect.
[0005] The mine water tank sludge cleaning and dewatering device of this utility model includes a frame base. The top of the frame base is connected to a support seat through multiple vibration springs. A dewatering box is fixedly connected to the top of the support seat. The bottom of the dewatering box is provided with a mud outlet. A plug corresponding to the mud outlet is slidably connected inside the support seat. A filter cylinder is connected to the edge of the mud outlet inside the dewatering box. A pressure plate is adapted to the filter cylinder. A pressure plate lifting drive assembly is connected between the pressure plate and the dewatering box. Vibration motors are installed on the left and right outer walls of the dewatering box. A water inlet is connected to the upper end of the side wall of the dewatering box. The water inlet penetrates the side wall of the filter cylinder. An upper water outlet is provided at the lower end of the side wall of the dewatering box.
[0006] Furthermore, the bottom of the frame base is fixedly connected with multiple support legs.
[0007] Furthermore, the filter cartridge includes two transverse filter plates and two longitudinal filter plates, which are arranged in a grid pattern.
[0008] Furthermore, the pressure plate lifting drive assembly includes a first mounting plate fixedly connected to the top of the dehydration tank, and a hydraulic cylinder is mounted on the first mounting plate, with the piston rod of the hydraulic cylinder fixedly connected to the pressure plate.
[0009] Furthermore, the top of the pressure plate is fixedly connected to multiple guide shafts, and the top of the dehydration tank is fixedly connected to a second mounting plate, on which guide sleeves corresponding to and adapted to the guide shafts are fixedly connected.
[0010] Furthermore, the plug is a box-type structure, with an opening at the top of the plug corresponding to the mud outlet, and a lower filter plate fixedly connected to the opening. The outer wall of the plug is provided with a lower water outlet that communicates with the interior.
[0011] Furthermore, each side of the support base is provided with a corresponding sliding groove, and the left and right sides of the block are provided with sliders that are adapted to the two sliding grooves.
[0012] Furthermore, a handle is fixedly connected to the seal.
[0013] Working principle and process:
[0014] During operation, two vibrating motors operate, causing the dewatering tank to vibrate up and down under the action of the vibrating springs. The muddy water enters the filter cylinder through the inlet. Under the action of the longitudinal filter plate, the transverse filter plate, and the plug, the sludge remains on the plug, while the water passes through the filter holes on the longitudinal and transverse filter plates into the dewatering tank and is discharged through the upper outlet. Due to the vibration of the dewatering tank, the dewatering efficiency of the sludge is increased. After the sludge is initially dewatered, the hydraulic cylinder is activated, and its piston rod extends, thereby driving the pressure plate to move downward under the guidance of the guide shaft and guide sleeve. The pressure plate and the plug work together to apply pressure to the sludge, thereby further squeezing out the water from the sludge. Then, the hydraulic cylinder drives the pressure plate to reset, and then pulls the plug, causing the plug to disengage from the mud outlet. Then, the sludge in the filter cylinder can fall out through the mud outlet.
[0015] The advantages of this utility model compared with the prior art are:
[0016] The mine water tank sludge cleaning and dewatering device of this utility model uses the up-and-down vibration of the dewatering box to perform preliminary and rapid dewatering of the sludge. Then, the hydraulic cylinder drives the pressure plate to squeeze and dewater the sludge. The dewatering pressure is relatively high, so the dewatering effect is better, thereby effectively reducing the transportation cost of the sludge. Attached Figure Description

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings:
[0025] Example 1:
[0026] like Figures 1 to 6 As shown, the mine water tank sludge cleaning and dewatering device of this utility model includes a frame base 2. The top of the frame base 2 is connected to a support seat 4 through multiple vibration springs 3. A dewatering box 11 is fixedly connected to the top of the support seat 4. The bottom of the dewatering box 11 is provided with a mud outlet 23. A plug 7 corresponding to the mud outlet 23 is slidably connected inside the support seat 4. A filter cylinder is connected to the edge of the mud outlet 23 inside the dewatering box 11. A pressure plate 19 is adapted to the filter cylinder. A pressure plate lifting drive assembly is connected between the pressure plate 19 and the dewatering box 11. Vibration motors 10 are installed on the left and right outer side walls of the dewatering box 11. A water inlet 12 is connected to the upper end of the side wall of the dewatering box 11. The water inlet 12 penetrates the side wall of the filter cylinder. An upper water outlet 21 is provided at the lower end of the side wall of the dewatering box 11.
[0027] In use, the two vibrating motors 10 operate, and under the action of the vibrating spring 3, the dewatering tank 11 vibrates up and down. The mud and water enter the filter cylinder through the inlet 12. Under the action of the filter holes and the plug 7, the sludge remains on the plug 7, and the water passes through the filter holes of the filter cylinder and enters the dewatering tank 11, and is discharged through the upper outlet 21. Due to the vibration of the dewatering tank 11, the dewatering efficiency of the sludge can be increased. After the sludge is initially dewatered, the pressure plate lifting drive component is activated, which drives the pressure plate 19 to move downward. The pressure plate 19 and the plug 7 work together to apply pressure to the sludge, thereby further squeezing out the water in the sludge. Then, the pressure plate lifting drive component reverses its action, which drives the pressure plate 19 to reset, and then pulls the plug 7 and makes the plug 7 separate from the mud outlet 23. Then the sludge in the filter cylinder can fall out through the mud outlet 23.
[0028] Example 2:
[0029] like Figures 1 to 6 As shown, based on Example 1,
[0030] Furthermore, the bottom of the frame base 2 is fixedly connected with multiple support legs 1. The dewatering tank 11 can be erected above the conveyor belt via the support legs 1, so that the sludge can fall directly onto the conveyor belt through the sludge outlet 23, which facilitates the output of the sludge.
[0031] Furthermore, the filter cartridge includes two transverse filter plates 14 and two longitudinal filter plates 15, which are arranged in a grid pattern. This allows both the transverse filter plates 14 and the longitudinal filter plates 15 to be connected to the inner wall of the dewatering tank 11, thereby improving the structural stability of the filter cartridge.
[0032] Furthermore, the pressure plate lifting drive assembly includes a first mounting plate 13 fixedly connected to the top of the dehydration tank 11. A hydraulic cylinder 20 is mounted on the first mounting plate 13, and the piston rod of the hydraulic cylinder 20 is fixedly connected to the pressure plate 19. The lifting and lowering movement of the pressure plate 19 can be driven by the extension and retraction of the piston rod of the hydraulic cylinder 20. The structure is simple and easy to control. At the same time, the use of hydraulic system not only provides higher pressure but also stable operation.
[0033] Furthermore, a plurality of guide shafts 17 are fixedly connected to the top of the pressure plate 19, and a second mounting plate 18 is fixedly connected to the top of the dehydration tank 11. Guide sleeves 16, which are adapted to each guide shaft 17, are fixedly connected to the second mounting plate 18. The pressure plate 19 is guided by the cooperation of the guide shafts 17 and the guide sleeves 16, thereby improving the operational stability of the pressure plate 19.
[0034] Furthermore, the sealing plug 7 has a box-type structure. An opening is provided at the top of the sealing plug 7 corresponding to the mud outlet 23, and a lower filter plate 22 is fixedly connected to the opening. A lower water outlet 8 communicating with the interior is provided on the outer wall of the sealing plug 7. After the muddy water enters the filter cylinder through the inlet 12, some of the water can pass through the lower filter plate 22 into the inner cavity of the sealing plug 7 and be discharged through the lower water outlet 8, further accelerating the separation of the two water bodies from the sludge and effectively improving the dewatering efficiency of the sludge.
[0035] Furthermore, each side of the support base 4 is provided with a corresponding sliding groove 5, and the left and right sides of the sealing block 7 are provided with sliders 6 that correspond to and are adapted to the two sliding grooves 5. The relative sliding of the sealing block 7 with respect to the support base 4 is achieved through the cooperation of the sliding grooves 5 and the sliders 6, resulting in a simple structure and stable operation.
[0036] Furthermore, a handle 9 is fixedly connected to the sealing block 7. The sealing block 7 can be pushed or pulled by holding the handle 9, making it easy to operate.
