Description

Coal washing circulating water filtration device Technical Field

[0001] The present invention relates to the technical field of coal washing water treatment, in particular to a coal washing circulating water filtering device. Background Art

[0002] Coal washing circulating water filtration technology is one of the treatment methods frequently adopted in the coal industry. By filtering the coal washing circulating water, impurities in the water can be effectively removed and the water quality can be improved, thereby meeting the requirements of production, environmental protection and other aspects. Usually, the coal washing circulating water is transported between the coal washing circulating water and the filtration device through a pipeline.

[0003] During the coal washing circulating water transportation and filtration process, since the coal washing water contains a large number of fine particles, the adhesion and accumulation of fine particles during long-term operation can easily lead to blockage of the water inlet between the pipe and the filter device. In order to prevent blockage, a rotating blade is set in the water inlet pipe for dredging and preventive treatment. The existing measures for installing the blades are mostly to weld them to the reserved position on the inner wall of the pipe. The position and angle of the welded fixed blades are usually permanent and difficult to adjust or change. If the position of the blades needs to be adjusted or replaced to adapt to changes in the fluid or operational requirements, the entire blade system needs to be re-welded or replaced, which increases the workload and cost.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0032] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0033] Example 1

[0034] 1 to 3 , which are the first embodiment of the present invention, provide a coal washing circulating water filtration device, which includes a fixing unit 100, including a fixing assembly 101 with an annular structure, a connecting assembly 102 arranged at the center of the fixing assembly 101, and a fixing rod 103 arranged between the fixing assembly 101 and the connecting assembly 102. The fixing assembly 101 is an annular structure as a whole, which fits the curvature of the inner wall of the pipe. Compared with the rectangular structure, the annular structure can reduce the contact area with the water flow, thereby reducing the impact force when the water flows. The connecting assembly 102 is fixedly connected to the fixing assembly 101 via the fixing rod 103. The connecting assembly 102 is used to connect the fixing unit 100 as a whole with other structures.

[0035] The adjustment unit 200 includes an adjustment component 201 located below the fixing assembly 101, three groups of adjustment components 202 arranged on the outside of the adjustment component 201, a limiting component 203 arranged above the adjustment component 201, and a return spring 204 arranged above the limiting component 203. The fixing assembly 101 is sleeved and installed on the adjustment component 201 through the connecting assembly 102. The three groups of adjustment components 202 are arc-shaped structures evenly distributed on the outside of the adjustment component 201. The inner end of the arc structure is fixedly connected to the adjustment component 201. The limiting component 203 is slidably sleeved on the adjustment component 201. The return spring 204 is also sleeved above the adjustment component 201 and the return spring 204 is also sleeved on the top of the adjustment component 201. The positioning spring 204 is located at the top of the limiting component 203, and the bottom of the limiting component 203 is clamped with the top of the connecting component 102; the supporting unit 300 includes three groups of supporting components 301 located on the fixing component 101, and a pushing component 302 arranged below one end of the supporting component 301. The three groups of supporting components 301 are evenly distributed above the fixing component 101. The inner ends of the supporting components 301 are close to the adjusting component 201, and the lower ends of the inner ends extend into the adjusting component 202 to be slidably connected. The pushing component 302 is arranged at the outer end of the supporting component 301, and the pushing component 302 and the supporting component 301 are perpendicular to each other, and the top end of the pushing component 302 is rotatably connected to the outer end of the supporting component 301;

[0036] The stirring unit 400 includes a driving component 401 disposed below the fixed component 101, and three groups of stirring components 402 disposed on the outside of the driving component 401. The top of the driving component 401 is fixedly connected to the adjusting component 201. The three groups of stirring components 402 are equally divided around the outside of the fixed component 401 in a manner perpendicular to the driving component 401, and each group of stirring components 402 is slidably connected to the fixed component 401.

[0037] During use, according to the actual size of the water inlet pipe, the device is placed as a whole inside the pipe, and the limiting component 203 is stretched upward so that the limiting component 203 is disengaged from the limiting engagement with the connecting assembly 102. Then, the adjusting unit 200 is driven to rotate as a whole by rotating the limiting component 203. During the rotation, the adjusting component 201 drives the corresponding three groups of support components 301 to expand outward through the three groups of adjustment components 202. The three groups of support components 301 will eventually abut against the inner wall of the pipe through outward expansion, thereby achieving the purpose of fixing the device as a whole in the pipe. By controlling the rotation amplitude of the adjustment component 202, the size of the device support and fixing range can be adjusted to meet more usage requirements. At the same time, during the movement of the support component 301, the support component 301 will drive the pushing component 302 to synchronously stretch the stirring component 402 below outward. The outward stretched stirring component 402 can adjust the stirring amplitude range of the stirred water flow, thereby better stirring and disturbing the flow to achieve the purpose of preventing blockage.

[0038] Example 2

[0039] 4 to 7 and 9 , a second embodiment of the present invention is shown. This embodiment differs from the first embodiment in that the expansion extension length of the support unit 300 is controlled by adjusting the limiting component 203, thereby achieving the purpose of fixing the device on pipes of different sizes and improving the flexibility of the device.

[0040] Compared with Example 1, further, the fixing assembly 101 includes a circular fixing ring frame 101a, and three groups of limiting slides 101b arranged on the fixing ring frame 101a, and the support component 301 is slidably connected in the limiting slide 101b, and is an annular structure with the fixing ring frame 101a. The limiting slide 101b is opened on the fixing ring frame 101a, and the overall structure is a C-shaped structure with the opening upward, and the three surfaces of the C-shaped structure are all rectangular surfaces. Therefore, the support component 301 slidably connected in the limiting slide 101b is limited by the limiting slide 101b and can only slide and expand horizontally to the outside of the fixing ring frame 101a.

[0041] Among them, the connecting component 102 includes a fixed plate 102a located at the center of the fixed ring frame 101a, a fixing hole 102b opened at the center of the fixed plate 102a, and a first limiting tooth 102c arranged on the upper extension of the fixed plate 102a. The fixed plate 102a is fixedly connected to the fixed ring frame 101a through a fixing rod 103, the fixing hole 102b is used to be sleeved on the adjusting component 201, and the first limiting tooth 102c is engaged with the bottom of the limiting component 203.

[0042] Among them, the adjusting component 201 includes a mounting plate 201a located below the fixed plate 102a, a limiting column 201b arranged above the mounting plate 201a, and a first limiting piece 201c arranged at the top of the limiting column 201b. The limiting column 201b is vertically arranged at the center position of the mounting plate 201a and is fixedly connected to it. The first limiting piece 201c is fixedly connected to the top of the limiting column 201b to play a limiting role. The limiting column 201b is a hexagonal column structure as a whole, and the six edge faces are rectangular faces. The limiting component 203 is slidably connected to the limiting column 201b as a whole. It is limited by its rectangular face and can only slide vertically above it and cannot rotate in a circular state.

[0043] Among them, the adjustment component 202 includes three groups of arc frames 202a located on the outside of the mounting plate 201a, and an arc chute 202b opened on each group of arc frames 202a. The arc frame 202a is an arc-shaped strip structure. Compared with the arc-shaped plate structure, it can reduce the resistance to the water flow at the water inlet and reduce the contact with particulate matter in the water flow, thereby avoiding particle adsorption and accumulation. Its inner end is fixedly connected to the outside of the mounting plate 201a, and the arc chute 202b is opened in the arc frame 202a. The two have the same curvature structure. One end of the support component 301 extends into the arc chute 202b and is slidably connected.

[0044] Among them, the limiting component 203 includes a sleeve 203a located on the limiting column 201b, an adjusting knob 203b arranged above the sleeve 203a, and a limiting chuck 203c arranged below the sleeve 203a. A limiting groove 203a-1 is provided at the axial position of the sleeve 203a, and is slidably sleeved on the limiting column 201b through the limiting groove 203a-1. The adjusting knob 203b is fixedly connected to the sleeve 203a, and the limiting chuck 203c is fixedly connected below the sleeve 203a. The limiting groove 203a-1 passes through the adjusting knob 203b and the limiting chuck 203c. A second limiting tooth 203c-1 that matches and engages with the first limiting tooth 102c is provided below the limiting chuck 203c.

[0045] The support component 301 includes a support frame 301a located on the fixed ring frame 101a, an abutment block 301b arranged at the outer end of the support frame 301a, a connecting shaft 301c arranged below the other end of the support frame 301a, and a second limiting piece 301d arranged below the connecting shaft 301c. The support frame 301a is slidably engaged in the limiting slide groove 101b as a whole. A rectangular slot 301a-1 is provided in the support frame 301a. The rectangular slot 301a-1 can reduce the obstruction of the support frame 301a to the water flow and abut against the water flow. Block 301b is fixedly connected to the outer end of the support frame 301a, and a rotating groove 301b-1 is provided on the abutment block 301b. The top of the pushing component 302 is rotatably connected in the rotating groove 301b-1. The connecting shaft 301c is fixedly connected to the bottom of the inner end of the support frame 301a and extends into the arc-shaped slide groove 202b. The second limiting piece 301d is fixedly connected to the bottom of the connecting shaft 301c to play a limiting role. The abutment block 301b is a two-piece structure, and the two pieces are fixed together by bolts to form the abutment block 301b.

[0046] During use, the limiting component 203 is pulled upward along the first limiting piece 201c, and the limiting component 203 will compress the return spring 204 to contract and store energy. At the same time, the second limiting tooth 203c-1 below the limiting component 203 disengages from the mutual limiting engagement with the first limiting tooth 102c, so that the limiting component 203 can rotate in a circle. When the limiting component 203 rotates, it will be limited by the limiting groove 203a-1 and the first limiting piece 201c, which will drive it to rotate, and then drive the adjustment component 201 and the adjustment component 202 to rotate as a whole. The rotating adjustment component 202 will push the connecting shaft 301c to slide along its arc structure through the arc slide groove 202b, and the support frame 301a is limited by the limiting slide groove 101b and cannot rotate with the adjustment component 202, so it can only expand outward. , the three groups of support parts 301 will expand outward at the same time, and will eventually tightly abut against the inner wall of the pipe, thereby achieving the purpose of limiting and fixing the entire device in the pipe; after adjusting the support part 301 to expand to the appropriate range, loosen the limiting part 203, and the pressure on the return spring 204 disappears, which will expand and squeeze the limiting part 203 outward, causing the limiting part 203 to slide downward and reset. At this time, the second limiting tooth 203c-1 engages with the first limiting tooth 102c, thereby limiting and fixing the adjustment unit 200, achieving the purpose of positioning and locking; it can be seen that the device can be installed and fixed by simply rotating the limiting part 203, making the assembly work of the device simpler, faster, and easier to install and maintain; at the same time, it can be adjusted accordingly according to the pipe size, suitable for pipes of different diameters and lengths, thereby meeting more usage requirements.

[0047] The remaining structures are the same as those of Example 1.

[0048] Example 3

[0049] 7 and 8 , which are the third embodiment of the present invention, this embodiment differs from the second embodiment in that the stirring range is adjusted synchronously with the fixed range of the device, thereby promoting the rotation and circulation of the fluid, promoting the separation of solid particles, and adding forced turbulence to the water inlet area to help break the adhesion of particles to the water inlet, effectively reducing the blockage problem of the water inlet, improving the separation efficiency and the reliability of the equipment, and better adapting to anti-blockage work.

[0050] Compared with Example 2, further, the pushing component 302 includes a turntable 302a located on the abutment block 301b, an adjusting piece 302b arranged at the top of the turntable 302a, and a limiting frame 302c arranged below the turntable 302a. The turntable 302a is rotatably connected in the rotating groove 301b-1, the adjusting piece 302b is rotatably connected to the top of the turntable 302a, and the limiting frame 302c is fixedly connected to the bottom of the turntable 302a, and the limiting frame 302c and the abutment block 301b are perpendicular to each other.

[0051] Furthermore, a first rotating shaft 302a-1 is provided on both sides of the turntable 302a, and the turntable 302a is rotatably connected to the rotating groove 301b-1 through the first rotating shaft 302a-1. A second rotating shaft 302a-2 is provided at the top of the turntable 302a, and the adjusting piece 302b is rotatably connected to the second rotating shaft 302a-2. The limit frame 302c is a fork-shaped structure, and a limit slot 302c-1 is provided between the two fork teeth, and the outer ends of the stirring component 402 extend into the limit slot 302c-1 on both sides.

[0052] During use, when the adjusting piece 302b rotates to be parallel to the turntable 302a, the two can form a disc structure and can rotate in the rotating groove 301b-1. When the adjusting piece 302b rotates to a cross-vertical state with the turntable 302a, the two ends of the adjusting piece 302b will be clamped and limited on the abutment block 301b, thereby limiting the entire pushing component 302 to be clamped on the abutment block 301b and unable to rotate.

[0053] Among them, the driving component 401 includes a driving motor 401a located below the mounting plate 201a, and three groups of rectangular shafts 401b arranged below the driving motor 401a and evenly distributed outward. A three-way joint 401a-1 is arranged below the driving motor 401a, and the inner end of the rectangular shaft 401b is fixedly connected to the outer end of the three-way joint 401a-1. The driving motor 401a provides power to drive the stirring component 402 to rotate, ensuring the continuous and stable rotation of the stirring component 402.

[0054] Among them, the stirring component 402 includes a blade 402a located on a rectangular shaft 401b, and a push rod 402b arranged on both sides of the outer end of the blade 402a. The stirring component 402 is driven to rotate by the driving component 401. A storage groove 402a-1 is opened inside the blade 402a. The rectangular shaft 401b extends into the storage groove 402a-1 and is slidably connected. The push rod 402b is fixed on both sides of the blade 402a, and the push rod 402b is an arc-shaped structure extending into the limit slot 302c-1. It is limited in the horizontal direction of the limit slot 302c-1, and the push rod 402b is an arc-shaped structure. When it rotates with the driving motor 401a as the center, its motion trajectory can form a circular structure, and the motion trajectory passes through the limit slot 302c-1.

[0055] During use, when the supporting component 301 moves outward and expands, the pushing component 302 will move synchronously with it, and the adjusting piece 302b will be rotated to be perpendicular to the turntable 302a in advance. At this time, the pushing component 302 cannot rotate in the rotating groove 301b-1 and can only be upright under the abutment block 301b in a vertical state. When the pushing component 302 moves, the pushing component 302 is connected to the limit of the push rod 402b through the limit frame 302c, and the pushing component 302 will drive the blade 402a along the rectangular axis 401b Stretching outward, the outward-stretched blade 402a can change the stirring range of the stirring unit 400, thereby achieving the expansion adjustment of the following device and adjusting the corresponding angle amplitude, so as to better achieve the anti-blocking effect; when the position of the stirring component 402 is adjusted, the adjusting plate 302b is rotated to a position parallel to the turntable 302a. At this time, the pushing component 302 can rotate under the abutment block 301b. When the stirring component 402 contacts the limit frame 302c during the rotation process, it will push it to rotate under the abutment block 301b, which will not hinder the normal rotation of the stirring component 402.

[0056] The remaining structures are the same as those of Example 2.
