Therefore, mine water has significant coal industry characteristics.

[0003] In order to prevent the discharge of mine water from polluting the external environment, the mine water needs to be treated when it is discharged. The existing treatment method is to aerate it through an aeration tank, then use activated sludge to mix and degrade it, then precipitate it in a sedimentation tank, and finally send the precipitated clean water to a filter tank for filtration before discharging it.

[0004] After sedimentation in the sedimentation tank, the precipitated sludge needs to be discharged. In the prior art, the most labor-intensive method for cleaning the sludge in the sludge tank is to manually salvage and clean it inside the sludge tank. The second is to extract and clean it with a sludge pump. However, the sludge pump extraction and cleaning requires manual cleaning of the sludge that is accumulated and sucked up by the sludge pump or manual movement of the sludge pump inside the sludge tank for cleaning. Both cleaning processes are relatively troublesome, and the manual labor intensity is high, and the cleaning efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, an automatic discharge device for sludge in mine water includes a sludge pool 1 and a sludge pump 2, two groups of vertical screw rods 3 are rotatably connected inside the sludge pool 1, and the outer wall of the vertical screw rod 3 is threadedly connected to a slider 301, a transverse screw rod 4 is rotatably connected between the two groups of sliders 301, and the outer wall of the transverse screw rod 4 is threadedly connected to a moving block 401, a group of sliders 301 is provided with a moving motor 402 on the top, and the output end of the moving motor 402 is transmission-connected to one end of the transverse screw rod 4 through a bevel gear set, the sludge pump 2 is fixedly connected to the bottom of the moving block 401 and the input end is in contact with the inner wall of the bottom of the sludge pool 1, and the output end of the sludge pump 2 is fixedly connected to a discharge pipe 203, and the end of the discharge pipe 203 extends out of the outside of the sludge pool 1.

[0023] like Figure 2 and Figure 3 As shown, the output end of the sludge pump 2 is fixedly connected to a feed pipe 201, and feed grooves 202 are provided on both sides of the feed pipe 201. The bottom of the feed pipe 201 abuts against the bottom inner wall of the sludge pool 1, and the movement of the sludge pump 2 driven by the moving block 401 is limited, and then the sludge in the process of the sludge pump 2 moving left and right is sucked through the feed grooves 202 on both sides.

[0024] like Figure 1 As shown, a driving motor 302 is fixedly connected to one side of the sludge pool 1, and the output end of the driving motor 302 is fixedly connected to one end of a group of vertical screw rods 3. The two groups of vertical screw rods 3 are connected through a transmission chain 303. The driving motor 302 drives one group of vertical screw rods 3 to rotate, and then the two groups of vertical screw rods 3 are synchronously driven and rotated through the transmission chain 303, so as to adjust the position of the sludge pump 2 and improve the convenience and stability of the position adjustment.

[0025] like Figure 1and Figure 2 As shown, feed hoods 6 are fixedly connected to both sides of the output end of the sludge pump 2, and the feed hood 6 is V-shaped. Through the setting of the feed hood 6, more sludge can enter the output end of the sludge pump 2 through the feed hood 6 for suction and discharge, thereby improving the cleaning efficiency. At the same time, the V-shaped setting facilitates the gathering and collection of sludge at the output end of the sludge pump 2.

[0026] like Figure 1 As shown, the sludge pool 1 is provided with a collecting box 5, and the end of the discharge pipe 203 is located inside the collecting box 5. Through the setting of the collecting box 5, the sludge discharged from the discharge pipe 203 is collected, thereby improving the convenience of collection.

[0027] like Figure 1 As shown, the top two sides of the sludge pool 1 are fixedly connected with fixing rods 7, and the outer wall of the fixing rod 7 is slidably connected with a mounting block 701, a connecting rod 702 is fixedly connected between the two groups of mounting blocks 701, and the outer wall of the connecting rod 702 is slidably connected with a fixing block 703, and the discharge pipe 203 is fixedly connected to the fixing block 703. When the vertical screw rod 3 or the horizontal screw rod 4 drives the sludge pump 2 to move inside the sludge pool 1 to adsorb and clean the sludge, the movement of the sludge pump 2 drives the discharge pipe 203 to move together, and the discharge pipe 203 slides on the connecting rod 702 through the fixing block 703 during the movement, or slides on the outer walls of the two groups of fixing rods 7 through the fixing block 703 and the connecting rod 702, so as to support the position movement of the discharge pipe 203 and improve the stability of the position movement of the discharge pipe 203. At the same time, the discharge pipe 203 is a telescopic pipe, which is convenient for the extension and retraction of the moving length during the movement of the sludge pump 2.

[0028] like Figure 1 and Figure 2 As shown, two groups of guide plates 101 are fixedly connected to the inner wall of the bottom of the sludge pool 1, and the two groups of guide plates 101 are respectively located below the two groups of vertical screw rods 3. The guide plates 101 are obliquely arranged below the vertical screw rods 3 to guide the sludge below the vertical screw rods 3 to other positions, thereby preventing the sludge from accumulating at the corners of the sludge pool 1 and being unable to be discharged by the sludge pump 2, thereby improving the cleaning effect.

[0029] The working principle of the utility model is as follows: when the user uses it, the water after the sludge is settled in the sludge pool 1 is discharged to leave the remaining sludge. In the initial state, the sludge pump 2 is at one side of the inner wall of the sludge pool 1, and then the moving motor 402 is started, the moving motor 402 drives the transverse screw rod 4 to rotate, the transverse screw rod 4 drives the moving block 401 to move, the moving block 401 drives the bottom sludge pump 2 to stick to the bottom of the sludge pool 1 for limited movement, and at the same time the sludge pump 2 is started. During the movement, the sludge pump 2 sucks out the sludge at the bottom of the sludge pool 1, and then discharges it to the outside of the sludge pool 1 through the discharge pipe 203, so as to clean the sludge inside the sludge pool 1. When the sludge pump 2 moves from one side of the inside of the sludge pool 1 to the other side, When one side is on, the driving motor 302 is started, and the driving motor 302 drives the two groups of vertical screw rods 3 to rotate synchronously, and the sliders 301 on the outer walls of the two groups of vertical screw rods 3 drive the transverse screw rod 4 to move, and the transverse screw rod 4 drives the sludge pump 2 to move vertically through the moving block 401, and the sludge pump 2 moves vertically one position, and then the moving motor 402 is started again to drive the sludge pump 2 to move through the transverse screw rod 4 and the moving block 401, and the sludge pump 2 sucks out and cleans the sludge in the moved position, and the sludge inside the sludge pool 1 is comprehensively cleaned through the repeated movement of the moving position of the sludge pump 2, without the need for manual entry into the sludge pool 1 to clean and suck out, thereby improving the convenience and efficiency of cleaning.

[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
