The background technology is as follows:
in the coal mining process, a large amount of slime water can be generated, and the common slime water treatment modes comprise the following three modes:
1. filtering sundries in mine sewage by utilizing goaf: the slime water is injected into the goaf from a high position, and after precipitation and filtration of the goaf, clear water flows out from a low position of the goaf, so that the aim of filtering sundries in mine sewage is fulfilled. The advantages are that: the filtering effect is good. But also has the following problems:
firstly, the elevation of a coal seam floor of a goaf is greatly influenced, the elevation of a water inlet is generally required to be higher, the elevation of a water outlet is lower, and the water inlet and the water outlet are specially reinforced;
secondly, a major hidden trouble is buried underground, and once the goaf moves again and the coal pillar is damaged, a possible flood accident and serious flood accidents can occur, and the major hidden trouble belongs to the mine and is forbidden.
2. The conventional dehydration device, namely a filter press for dehydration, has the following working principle: the pressure pump is used for pressing the coal slime into a closed filter chamber formed by two adjacent filter plates, so that pressure difference is formed at two sides of the filter cloth, and solid-liquid separation is realized. The filter press is generally composed of a head plate, a tail plate, a filter plate, a hydraulic cylinder, a main beam, a transmission device, a pulling device and the like. The piston of the hydraulic cylinder pushes the head plate, so that the filter plates are pressed against the adjacent filter plates to form a filter chamber, the slurry pump sends the coal slurry into the filter chamber, the water is discharged through the filter cloth and the liquid outlet, and the solid slurry forms a filter cake in the filter chamber. After the filter chamber is filled with the slime water, the slime water is continuously pressurized and filtered by a high-pressure pump, so that solid and liquid are separated in the filter chamber. The problems that exist are:
firstly, the equipment has large external dimension, is not convenient for a plurality of equipment to be simultaneously arranged and is not convenient for the application of underground operation sites;

In the present embodiment, an annular fixing band 52 is further provided on the outer circumference of the dewatering cylinder body 31 and the driving cylinder 2.
The driving oil cylinder 2 is a bidirectional hydraulic cylinder, and the driving oil cylinder 2 reciprocates, so that the effect that one driving oil cylinder 2 drives two dewatering cylinders 3 can be realized. After the actuation of the drive cylinders 2, the slime water is led into the fluid inlets 312 of the two dewatering cylinders 3, respectively, specifically: the left dewatering cylinder 3 sucks in the slime water, and the right dewatering cylinder 3 is in a dewatering state; the dewatering cylinder 3 on the right sucks in slime water while the dewatering cylinder 3 on the left is in a dewatering state. Thus, the continuous dehydration operation can be ensured.
The end cover 32 of the dewatering cylinder 3 serves as a support for balancing the piston rod 33 of the dewatering cylinder, guides the piston rod 33 of the dewatering cylinder, blocks the water column of sewage splashed from the water permeable piston 34 in the dewatering process, and gathers the sewage through the water outlet of the end cover 32 and discharges the sewage out of the dewatering cylinder body 31.
The permeable piston 34 of the dewatering cylinder 3 has the function of extruding the slime water in the dewatering cylinder body 31 under the drive of the dewatering cylinder piston rod 33; secondly, sewage in the slime water passes through a permeable piston 34 device in the extrusion process so as to realize the slime water separation; thirdly, pushing the separated coal slime blocks out of the dewatering cylinder body 31; fourthly, under the drive of the reverse movement of the dewatering cylinder piston rod 33, negative pressure is formed in the dewatering cylinder body 31, and the slime water is sucked into the dewatering cylinder body 31 from the slime water storage pool 7.
The water permeable baffle 37 firstly prevents the coal slime water from overflowing the dewatering cylinder body 31 in the process of extruding the coal slime water in the dewatering cylinder 3; secondly, sewage in the slime water is separated out through a water permeable baffle 37 device in the extrusion process; thirdly, after the pressure of the hydraulic system of the driving oil cylinder 2 reaches a rated value, the water permeable baffle 37 is instantaneously separated from a gap between the first annular clamping plate 35 and the second annular clamping plate 36 under the drive of the rotary oil cylinder 392, so that the coal slime blocks are pushed out of the dewatering cylinder body 31 in the running process of the water permeable piston 34; fourthly, under the drive of the reverse movement of the dewatering cylinder piston rod 33, negative pressure is formed in the dewatering cylinder 3, and the slime water is sucked into the dewatering cylinder body 31. In this embodiment, the distance between the first annular clamping plate 35 and the second annular clamping plate 36 can be adjusted by adjusting the bolts 314. Meanwhile, the first annular clamping plate 35 and the second annular clamping plate 36 are provided with bolt holes on only one half of the circumferences, and no bolt holes are provided on the remaining half of the circumferences, so that a rotating channel can be provided for the rotation of the water permeable baffle 37, and smooth rotation of the water permeable baffle 37 is ensured.
In this embodiment, by controlling the expansion and contraction of the piston rod of the rotary cylinder 392, the baffle driving link 393 is driven to rotate, and the rotary shaft 394 is driven to rotate, further the baffle leaf handle 391 is driven to rotate, and finally the water permeable baffle 37 is driven to rotate.
The arched cleat support frames 38 may provide support for the transparent water deflector 313. Meanwhile, in the dehydration process, water sprayed through the water permeable baffle 37 can be blocked by the clamping plate supporting frame 38 and the transparent water baffle 313 together and then falls into the lower 4# water guide groove 67.
In this embodiment, the separated water discharged from the end cap water outlet 310 is collected by the # 1 water guiding groove 61 and then enters the # 2 water guiding groove 63 through the # 1 water guiding pipe 62; since the 4# water guide groove 67 is inclined downward in a natural state toward the side close to the dewatering tank 3, and the amount of water discharged from the water permeable barrier 37 is small, the water discharged from the water permeable barrier 37 is collected by the 4# water guide groove 67, flows into the 3# water guide groove 65, enters the 3# water guide pipe 66 through the 4# water guide pipe 68, and enters the 2# water guide groove 63 through the 2# water guide pipe 64. After the dehydrated coal slime blocks are pushed out of the dewatering cylinder body 31 and fall to one end, far away from the dewatering cylinder 3, of the 4# water guide groove 67, under the action of gravity of the coal slime blocks, the weight 610 is lifted, the balance of the 4# water guide groove 67 is broken, the fixed pulley 69 rotates to drive the 4# water guide groove 67 to incline downwards to one end far away from the dewatering cylinder 3, and then the coal slime blocks slide to a conveying system, and then the 4# water guide groove 67 returns to the original position under the action of the weight 610.
In this embodiment, the whole frame is welded by i-steel, and the upper plane of the fixing device of the i-steel frame 1 is ensured to be in a uniform horizontal plane during the installation. The design and application of the I-steel frame 1 can realize the rapid installation and centering of parts and the whole machine lifting and moving of the embodiment.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
