Description

Technical Field

[0002] Coal slurry is an important working medium in the coal preparation process, and also an industrial wastewater generated during the wet coal processing. Coal slurry treatment in coal preparation involves a wide range of aspects, requires significant investment, and is difficult to manage. Coal slurry is particularly stable; it will not settle naturally even after several months of standing, making treatment extremely challenging. To meet the water quality requirements of closed-loop coal slurry circulation, prevent water quality deterioration during the circulation process, and protect the environment, research into coal slurry treatment technologies is becoming increasingly necessary. Due to differences in the properties of raw coal, coal slurry from coal mines exhibits both certain differences and commonalities in its properties.

[0003] Existing coal slurry water treatment devices have relatively small filter holes to filter out small coal slurry pieces. When passing through larger coal slurry pieces, the holes are easily damaged, resulting in unsatisfactory filtration. Furthermore, replacing the filter screen requires stopping the coal slurry water supply, leading to low treatment efficiency. In addition, each process in the existing coal slurry water treatment devices requires dedicated personnel to monitor, resulting in significant labor costs. Utility Model Content

Furthermore, replacing the filter screen requires stopping the coal slurry water supply, leading to low treatment efficiency. In addition, existing coal slurry water treatment devices require dedicated personnel to monitor each process, resulting in significant labor costs.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a coal slurry water treatment device for coal washing and processing, including a load-bearing frame and four support rods. The four support rods are respectively installed on the side wall of the load-bearing frame. A positioning frame is installed on the lower wall of the load-bearing frame. A coal slurry conveying structure is installed on the inner wall of the positioning frame. A wastewater treatment structure is installed below the coal slurry conveying structure. A coal slurry treatment structure is installed below the coal slurry conveying structure.

[0006] As a further embodiment of this utility model: the coal slime conveying structure includes: a conveying pipe, a conveying filter, a fixed frame, and a guide frame; the conveying pipe is installed on the inner wall of the positioning frame, the conveying filter is installed on the lower wall of the conveying pipe, the fixed frame is installed on the lower wall of the load-bearing frame, and the guide frame is installed on the inner wall of the fixed frame, corresponding to the lower part of the conveying filter.

[0007] As a further embodiment of this utility model: the wastewater treatment structure includes: a coal slime filter screen, a wastewater treatment tank, a chute, an auxiliary filter screen, a drain pipe, and a water pump; the coal slime filter screen is installed below the guide frame, the wastewater treatment tank is installed on the lower wall of the coal slime filter screen, the chute is opened on the inner wall of the wastewater treatment tank, the auxiliary filter screen is installed in the chute, the drain pipe is connected to the bottom of the wastewater treatment tank, and the water pump is connected to the drain pipe.

[0008] As a further embodiment of this utility model: the coal slime treatment structure includes: a fixed base, several telescopic sleeves, several telescopic rods, a support platform, a trigger block, an alarm switch, two sliders, and a coal slime collection box; the fixed base is installed on the lower wall of the wastewater treatment tank, the several telescopic sleeves are respectively installed on the upper wall of the fixed base, the several telescopic rods are respectively installed on the inner wall of the several telescopic sleeves, the support platform has two slides and is installed on the upper wall of the several telescopic rods, the trigger block is installed on the lower wall of the support platform, the alarm switch is installed on the upper wall of the fixed base, the two sliders are respectively installed in the two slides of the support platform, and the coal slime collection box is installed on the upper wall of the two sliders.

[0012] The present invention adopts the above technical solution and has the following advantages compared with the prior art:

[0013] The initial filtration process uses a conveyor filter to separate larger coal slurry pieces from the wastewater using gravity and density. Then, a coal slurry filter and auxiliary filters work together to achieve continuous separation of coal slurry and water. The multi-stage filtration system, consisting of a conveyor filter with large pores and a coal slurry filter with small pores, enhances the filtration effect. This solves the problems of existing coal slurry water treatment devices, which use finely sized filter holes to filter small coal slurry pieces, making them prone to damage when passing through larger pieces, resulting in unsatisfactory filtration. Furthermore, replacing the filter requires stopping the coal slurry water supply, leading to low treatment efficiency.

[0014] When the coal slime collection box enters the coal slime block, the support platform, under the influence of gravity, drives several telescopic rods to descend along several telescopic sleeves. The shock-absorbing springs contract, and when the support platform drives the trigger block to trigger the alarm switch, the alarm sounds. This solves the problem that existing coal slime water treatment devices require dedicated personnel to monitor each process, resulting in significant manpower consumption.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1, please refer to Figures 1-4 A coal slurry water treatment device for coal washing and processing includes a load-bearing frame 1 and four support rods 2. The four support rods 2 are respectively installed on the side wall of the load-bearing frame 1. A positioning frame 3 is installed on the lower wall of the load-bearing frame 1. A coal slurry conveying structure is installed on the inner wall of the positioning frame 3. A wastewater treatment structure is installed below the coal slurry conveying structure. A coal slurry treatment structure is installed below the coal slurry conveying structure.

[0022] Please see Figure 2 The coal slurry conveying structure includes: a conveying pipe 4, a conveying filter 5, a fixed frame 6, and a guide frame 7; the conveying pipe 4 is installed on the inner wall of the positioning frame 3, the conveying filter 5 is installed on the lower wall of the conveying pipe 4, the fixed frame 6 is installed on the lower wall of the load-bearing frame 1, and the guide frame 7 is installed on the inner wall of the fixed frame 6, corresponding to the lower part of the conveying filter 5.

[0023] Please see Figure 3 The wastewater treatment structure includes: a coal slime filter screen 8, a wastewater treatment tank 9, a chute 10, an auxiliary filter screen 11, a drain pipe 12, and a water pump 13; the coal slime filter screen 8 is installed below the guide frame 7, the wastewater treatment tank 9 is installed on the lower wall of the coal slime filter screen 8, the chute 10 is opened on the inner wall of the wastewater treatment tank 9, the auxiliary filter screen 11 is installed in the chute 10, the drain pipe 12 is connected to the bottom of the wastewater treatment tank 9, and the water pump 13 is connected to the drain pipe 12.

[0024] Please see Figure 3 The side walls of the coal slurry filter screen 8 and the auxiliary filter screen 11 are equipped with auxiliary handles 22. In this embodiment, the coal slurry water is filtered by the auxiliary filter screen 11. When the operator replaces the coal slurry filter screen 8, he / she holds the auxiliary handle 22 and pulls the auxiliary filter screen 11 out along the slide groove 10 to clean and replace the auxiliary filter screen 11.

[0025] In this embodiment, the coal slurry is initially filtered by the conveying filter screen 5, and larger pieces of coal slurry are separated from the wastewater by gravity and density. Then, the coal slurry filter screen 8 and the auxiliary filter screen 11 work together to achieve continuous separation of coal slurry water.

[0026] Specifically, when the coal slurry water passes through the conveying pipe 4, larger coal slurry particles flow through the conveying filter screen 5 and enter the coal slurry collection box 21 through the conveying pipe 4. Smaller coal slurry particles, after passing through the conveying filter screen 5, pass through the guide frame 7 and enter the wastewater treatment box 9. The fixing frame 6 is used to fix the guide frame 7, the positioning frame 3 is used to fix the conveying pipe 4, the load-bearing frame 1 is used to fix the fixing frame 6, and the four support rods 2 are used to support the load-bearing frame 1. When the preliminarily filtered coal slurry water enters the wastewater treatment box 9 through the fixed guide frame 7, it passes through the coal slurry filter screen 8... Finer coal slurry lumps separate from water, with the lumps remaining on the coal slurry filter screen 8. Water passes through the auxiliary filter screen 11 and enters the wastewater treatment tank 9. Finally, the water pump 13 pumps the water out through the drain pipe 12. When the amount of coal slurry lumps stored in the coal slurry filter screen 8 reaches a certain level, the operator removes and replaces the coal slurry filter screen 8. During this process, the coal slurry water is filtered by the auxiliary filter screen 11. After the operator replaces the coal slurry filter screen 8, they hold the auxiliary handle 22 and pull the auxiliary filter screen 11 out along the slide 10. Cleaning and replacing the auxiliary filter screen 11 can achieve continuous separation of coal slurry water.

[0027] Example 2, please refer to Figure 4The coal sludge treatment structure includes: a fixed base 14, several telescopic sleeves 15, several telescopic rods 16, a support platform 17, a trigger block 18, an alarm switch 19, two sliders 20, and a coal sludge collection box 21. The fixed base 14 is installed on the lower wall of the wastewater treatment tank 9. Several telescopic sleeves 15 are respectively installed on the upper wall of the fixed base 14. Several telescopic rods 16 are respectively installed on the inner wall of several telescopic sleeves 15. The support platform 17 has two slides and is installed on the upper wall of several telescopic rods 16. The trigger block 18 is installed on the lower wall of the support platform 17. The alarm switch 19 is installed on the upper wall of the fixed base 14. The two sliders 20 are respectively installed in the two slides opened on the support platform 17. The coal sludge collection box 21 is installed on the upper wall of the two sliders 20.

[0028] Please see Figure 4 The telescopic sleeves 15 and the telescopic rods 16 are connected by dampers. In this embodiment, the dampers can reduce vibration and make the support platform 17 move more stably.

[0029] Please see Figure 4 Several conveying telescopic rods 16 are respectively fitted with shock-absorbing springs 23 on their outer walls. In this embodiment, the operator holds the coal slurry collection box 21 and drives the two sliders 20 to be pulled out along the two slides opened on the support platform 17. At this time, the shock-absorbing springs 23 contract and reset, driving the support platform 17 to reset.

[0030] In this embodiment, when the coal slurry collection box 21 enters the coal slurry block, the support platform 17 is affected by gravity and drives several telescopic rods 16 to descend along several telescopic sleeves 15. The shock-absorbing spring 23 contracts. When the support platform 17 drives the trigger block 18 to trigger the alarm switch 19, the alarm sounds.

[0031] Specifically, when the coal slurry collection box 21 enters the coal slurry block, the support platform 17, under the influence of gravity, causes several telescopic rods 16 to descend along several telescopic sleeves 15, and the shock-absorbing spring 23 to contract. When the support platform 17 drives the trigger block 18 to trigger the alarm switch 19, the alarm sounds. The operator holds the coal slurry collection box 21 and drives the two sliders 20 to be pulled out along the two slides opened on the support platform 17. At this time, the shock-absorbing spring 23 contracts and resets, causing the support platform 17 to reset, the alarm is cleared, and the operator can replace the coal slurry collection box 21.
