Technical Field
[0001] This utility model relates to the field of coal processing technology, and in particular to a coal slurry water treatment device for coal washing and processing. Background Technology
[0002] In the coal washing and processing industry, the treatment of coal slurry water is a crucial step. The coal washing process generates a large amount of coal slurry water containing coal slurry, impurities, and chemical agents. If not properly treated, it will not only waste water resources but also potentially cause environmental pollution. Currently, the common method for treating coal slurry water is to first perform preliminary filtration to remove larger particulate impurities, and then further purify it by adding catalytic agents. In the preliminary filtration stage, traditional filtration equipment mostly uses fixed filter screens. After a period of use, a large amount of impurities easily adhere to the surface of the filter screen, causing the mesh to become clogged and affecting the filtration effect. Moreover, cleaning the filter screen often requires disassembly, which is cumbersome, time-consuming, and labor-intensive, reducing the overall processing efficiency. In the mixing stage, existing mixing devices mostly use simple mixing blade structures, which are unevenly mixed and easily cause the catalytic agents to precipitate, failing to fully exert their effects. This results in poor coal slurry water treatment and makes it difficult to meet increasingly stringent environmental protection and production requirements. Therefore, we have introduced a coal slurry water treatment device for coal washing and processing. Utility Model Content
[0003] The main objective of this invention is to provide a coal slurry water treatment device for coal washing and processing, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A coal slurry water treatment device for coal washing and processing includes a treatment box, a fixing plate fixedly connected to the upper front end of the treatment box, a side box fixedly connected to the lower right end of the treatment box, a stirring device fixedly connected to the right end of the side box, an inlet pipe and a drain pipe fixedly connected to the upper left end and the lower left end of the treatment box, respectively, a slot is opened at the upper end of the treatment box, and a filter device is fixedly connected to the lower end of the fixing plate.
[0006] The stirring device includes a drive motor. The output end of the drive motor passes through the side box and is fixedly connected to a main gear. A secondary gear is meshed with the rear part of the outer surface of the main gear. A rotating rod is fixedly connected to the middle of the left end of the secondary gear. A connecting shaft is fixedly connected to the right end of the secondary gear. Several stirring blades are fixedly connected to the outer surface of the rotating rod. The drive motor is fixedly connected to the right end of the side box.
[0007] Preferably, the filtration device includes a cylinder, the output end of which passes through a fixed plate and is fixedly connected to a connecting plate. A clamping plate is fixedly connected to the lower end of the connecting plate, and a filter screen is fixedly connected to the bottom of the clamping plate. Sliding grooves are formed on both the front and rear walls of the clamping plate. A displacement brush plate is slidably connected between the front and rear walls of the clamping plate. Several brush strips are fixedly connected to the lower end of the displacement brush plate, and a handle is fixedly connected to the upper rear part of the displacement brush plate. The cylinder is fixedly connected to the lower end of the fixed plate.
[0008] Preferably, the card plate is movably connected in the card slot, and the front end and rear end of the displacement brush plate are slidably connected in the slide groove.
[0009] Preferably, the filter screen has a honeycomb structure, and several brush strips are tightly attached to the surface of the filter screen.
[0010] Preferably, the right end of the connecting shaft is movably connected to the rear part of the right side box wall of the side box via a bearing, and the left end of the rotating rod is movably connected to the lower part of the left side box wall of the processing box via a bearing.
[0011] Preferably, all of the stirring blades have a wavy structure, and the stirring blades are arranged in a ring around the rotating rod.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The filtration device of this unit adopts a liftable honeycomb filter screen design. The connecting plate and clamping plate are driven by a cylinder to achieve the vertical movement of the filter screen, allowing for convenient and flexible adjustment of the filtration position to meet the treatment needs of different stages. Simultaneously, the honeycomb structure of the filter screen increases the filtration area, enabling more efficient interception of larger particulate impurities in the coal slurry water. Furthermore, the coordinated design of the displacement brush plate, brush strips, and slide groove allows operators to move the displacement brush plate along the slide groove without disassembling the filter screen. The brush strips, which are in close contact with the filter screen surface, can promptly clean impurities, preventing mesh clogging, significantly reducing cleaning time and labor intensity, ensuring continuous and efficient filtration, and significantly improving the overall efficiency of coal slurry water treatment.
[0014] 2. In this utility model, the stirring device transmits power stably to the rotating rod through the meshing transmission of the drive motor, main gear, and secondary gear, ensuring smooth operation of the stirring process. The wavy and annularly distributed stirring blades on the rotating rod increase the contact area with the coal slurry and catalyst mixture compared to the traditional simple blade structure, enabling stirring from multiple angles and effectively improving the uniformity of stirring. The connecting shaft and the rotating rod are movably connected to the side box and the treatment box through bearings, reducing rotational friction resistance, reducing equipment wear, and ensuring the stability of the stirring structure. This allows the catalyst to be evenly distributed in the coal slurry, effectively avoiding sedimentation, thereby improving the utilization efficiency of the catalyst, further enhancing the purification effect of the coal slurry, and better meeting environmental protection and production requirements.

[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A coal slurry water treatment device for coal washing and processing includes a treatment box 1. A fixing plate 5 is fixedly connected to the upper front end of the treatment box 1. A side box 2 is fixedly connected to the lower right end of the treatment box 1. A stirring device 3 is fixedly connected to the right end of the side box 2. A water inlet pipe 8 and a drain pipe 4 are fixedly connected to the upper left end and the lower left end of the treatment box 1, respectively. A slot 6 is opened at the upper end of the treatment box 1. A filter device 7 is fixedly connected to the lower end of the fixing plate 5.
[0025] In this embodiment, the stirring device 3 includes a drive motor 31. The output end of the drive motor 31 passes through the side box 2 and is fixedly connected to a main gear 32. The rear part of the outer surface of the main gear 32 is meshed with a secondary gear 33. The middle part of the left end of the secondary gear 33 is fixedly connected to a rotating rod 34. The right end of the secondary gear 33 is fixedly connected to a connecting shaft 36. The outer surface of the rotating rod 34 is fixedly connected to several stirring blades 35. The drive motor 31 is fixedly connected to the right end of the side box 2. The right end of the connecting shaft 36 is movably connected to the rear part of the right box wall of the side box 2 through a bearing. The left end of the rotating rod 34 is movably connected to the lower part of the left box wall of the processing box 1 through a bearing. The several stirring blades 35 are all of wavy structure and are arranged in a ring around the rotating rod 34.
[0026] Through the above scheme: when the stirring device 3 is running, the drive motor 31 fixed to the right end of the side box 2 starts, and its output end passes through the side box 2 and drives the main gear 32 to rotate. The rear part of the outer surface of the main gear 32 meshes with the secondary gear 33, thereby driving the secondary gear 33 to rotate. The rotating rod 34 fixedly connected to the middle of the left end of the secondary gear 33 and the connecting shaft 36 fixedly connected to the right end rotate synchronously. The right end of the connecting shaft 36 is movably connected to the rear part of the right box wall of the side box 2 through a bearing. The left end of the rotating rod 34 is movably connected to the lower part of the left box wall of the processing box 1 through a bearing to ensure stable rotation. When the rotating rod 34 rotates, several wavy-shaped stirring blades 35 fixedly connected to the outer surface and distributed in a ring around the rotating rod 34 rotate accordingly. The stirring device 31 stirs the materials inside the processing chamber 1. The drive motor 31 transmits power stably to the rotating rod 34 through the meshing of the main gear 32 and the secondary gear 33, ensuring the smooth operation of the stirring device 3. The wave-shaped and annularly distributed stirring blades 35 increase the contact area with the materials, and can stir the materials from multiple angles during rotation, improving the uniformity and efficiency of stirring. The connecting shaft 36 and the rotating rod 34 are movably connected to the side box 2 and the processing chamber 1 respectively through bearings, reducing frictional resistance during rotation, reducing equipment wear, extending service life, and ensuring the stability of the device during stirring, resulting in better material stirring effect. It is suitable for the stirring and processing needs of various materials, improving the practicality and reliability of the equipment.
[0027] In this embodiment, the filter device 7 includes a cylinder 71. The output end of the cylinder 71 passes through the fixed plate 5 and is fixedly connected to a connecting plate 73. A clamping plate 72 is fixedly connected to the lower end of the connecting plate 73. A filter screen 74 is fixedly connected to the bottom of the clamping plate 72. The front and rear walls of the clamping plate 72 are both provided with sliding grooves 75. A displacement brush plate 76 is slidably connected between the front and rear walls of the clamping plate 72. Several brush strips 77 are fixedly connected to the lower end of the displacement brush plate 76. A handle 78 is fixedly connected to the upper rear part of the displacement brush plate 76. The cylinder 71 is fixedly connected to the lower end of the fixed plate 5. The clamping plate 72 is movably connected in the slot 6. The front and rear ends of the displacement brush plate 76 are slidably connected in the sliding grooves 75. The filter screen 74 has a honeycomb structure, and several brush strips 77 are tightly attached to the surface of the filter screen 74.
[0028] Through the above scheme: When the filter device 7 is running, the cylinder 71 fixed to the lower end of the fixed plate 5 is activated. Its output end passes through the fixed plate 5 and drives the connecting plate 73 to move. The clamping plate 72 fixedly connected to the lower end of the connecting plate 73 moves accordingly. The filter screen 74 fixedly connected to the bottom of the clamping plate 72 is also moved, realizing vertical displacement. The clamping plate 72 is inserted into or removed from the slot 6 to complete the adjustment of the filter position. During the filtration process, the honeycomb-structured filter screen 74 intercepts and filters the material. When it is necessary to clean the filter screen 74, the operator holds the handle 78 at the upper rear end of the displacement brush plate 76. Since the front end and rear end of the displacement brush plate 76 are slidably connected in the grooves 75 of the front and rear plates of the clamping plate 72, the displacement brush can be moved along the grooves 75. The lower end of the displacement brush plate 76 is fixedly connected to several brush strips 77 that are in close contact with the surface of the filter screen 74. During the movement, these brush strips clean impurities from the surface of the filter screen 74. The cylinder 71 drives the connecting plate 73, the clamping plate 72, and the filter screen 74, enabling flexible adjustment of the position of the filter screen 74. The honeycomb structure of the filter screen 74 has a large filtration area and good interception effect, which can efficiently separate impurities from materials. Through the cooperative design of the displacement brush plate 76, the brush strips 77, and the slide groove 75, operators can easily clean the filter screen 74 without disassembling it, reducing cleaning time and labor intensity. At the same time, it avoids damage to the filter screen 74 that may be caused during disassembly, thus extending the service life of the filter screen 74.
[0029] It should be noted that this utility model is a coal slurry water treatment device for coal washing and processing. Before the coal slurry water and catalyst enter the treatment tank 1 through the inlet pipe 8, the cylinder 71 needs to be activated in advance. The output end of the cylinder 71 will push the connecting plate 73, which in turn will drive the clamping plate 72 and the filter screen 74 to move downward together until the clamping plate 72 is accurately inserted into the clamping groove 6 at the upper end of the treatment tank 1, so that the honeycomb structure filter screen 74 is completely inserted into the treatment tank 1. Subsequently, the mixture of coal slurry water and catalyst flows into the treatment tank 1 through the inlet pipe 8. At this point, the honeycomb filter screen 74 begins to function, performing preliminary filtration of the mixture and effectively intercepting larger particles of impurities. The water, purified by this preliminary filtration, is then discharged from the drain pipe 4. During the filtration process, if a large amount of impurities adhere to the surface of the filter screen 74, potentially affecting the filtration effect, the operator can push the displacement brush plate 76 using the handle 78. Since the front and rear ends of the displacement brush plate 76 slide within the grooves 75 on the front and rear walls of the clamping plate 72, the several brush strips 77 at their lower ends, which are in close contact with the surface of the filter screen 74, will... The impurities on the filter screen 74 are brushed off to prevent clogging of the screen and ensure continuous and efficient filtration until the preliminary filtration stage is completed. After the preliminary filtration is completed, the drive motor 31 is turned on. The output of the drive motor 31 drives the main gear 32 to rotate. The main gear 32 meshes with the secondary gear 33, causing the secondary gear 33 to rotate accordingly. When the secondary gear 33 rotates, it drives the rotating rod 34 and the connecting shaft 36 to rotate synchronously. The several stirring blades 35 on the outer surface of the rotating rod 34, which are wavy and distributed in a ring, will fully stir the mixture of coal slurry water and catalyst in the treatment box 1 after preliminary filtration. This stirring operation can effectively prevent the catalyst from precipitating, thereby improving the utilization efficiency of the catalyst and further improving the treatment effect of coal slurry water. During this stirring process, the right end of the connecting shaft 36 is movably connected to the rear of the right box wall of the side box 2 through a bearing, and the left end of the rotating rod 34 is movably connected to the lower part of the left box wall of the treatment box 1 through a bearing. This connection method ensures the stability of the rotation of the entire stirring structure and ensures smooth and continuous operation of the stirring work.
