Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sedimentation tank technology, and specifically relates to a sedimentation tank for mud and water treatment. Background Technology
[0002] Industrial production processes generate large amounts of muddy water containing a lot of water. Using sedimentation tanks to simply separate the muddy water can greatly improve the efficiency of subsequent treatment. Sedimentation tanks are structures that use the natural sedimentation or coagulation sedimentation of water to achieve simple separation of mud and water. They are widely used in mining processing, sewage treatment and industrial wastewater treatment. Traditional sedimentation methods include horizontal flow, vertical flow and radial flow. Sedimentation tanks are generally hollow tanks with an independent cavity. After sewage enters the cavity from the inlet, it will undergo natural sedimentation or flocculation sedimentation in the sedimentation tank, accumulating sludge at the bottom of the tank, and then the sludge is discharged.
[0003] The patent with publication number CN212467226U discloses a sedimentation tank for mud and water treatment. A rear horizontal baffle is arranged on one side of the outlet pipe, and a filter chamber is arranged on the rear horizontal baffle. The filter chamber includes two grid-like baffles at the front and rear, and filter particles such as quartz sand or vermiculite can be arranged inside it, so as to achieve simple, efficient and low-cost filtration.
[0004] However, since the horizontal baffles cannot be removed, replacing filter particles such as quartz sand or vermiculite is quite troublesome. Utility Model Content
[0005] The purpose of this invention is to provide a sedimentation tank for mud and water treatment that facilitates the replacement of quartz sand.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge treatment sedimentation tank, comprising: The sedimentation tank body has an upward-facing sedimentation chamber, and the two ends of the sedimentation chamber are respectively provided with an inlet and an outlet trough. The filter frame has an upward-facing filter groove, and a filter inlet groove and a filter outlet groove are respectively provided on opposite sides of the filter groove. Quartz sand is installed in the filter groove. Connecting mounting blocks are fixed at both ends of the filter frame. The connecting mounting blocks have downward-facing slots. The upper end of the side wall of the sedimentation tank body is inserted into the slots. The filter outlet groove is connected to the effluent groove.
[0007] Furthermore, a fixing frame is fixed to the side of the filter frame facing away from the filter inlet, and the fixing frame is inserted into the outlet tank.
[0008] Furthermore, a collection plate is fixed on the outer wall of the sedimentation tank body, which is located below the fixed frame. The collection plate is provided with an upward-facing collection trough, and the bottom of the collection trough is provided with a collection outlet hole.
[0009] Furthermore, a surrounding plate is fixed to the upper end of the collecting plate.
[0010] Furthermore, the connecting mounting block is provided with a connecting hole that communicates with the slot, and the sedimentation tank body is provided with a threaded hole corresponding to the connecting hole. A connecting bolt passes through the connecting hole and is threadedly connected to the threaded hole.
[0011] Furthermore, the connecting bolt includes a screw and two fixing rings fixed on the screw. A fixing shaft corresponding to the connecting bolt is fixed on the connecting mounting block. A fixing plate is fixed to one end of the fixing shaft away from the connecting mounting block. The fixing shaft is connected to the connecting plate. The two ends of the connecting plate are respectively provided with a first connecting hole and a second connecting hole. The fixing shaft passes through the first connecting hole, the screw passes through the second connecting hole, and the connecting plate is located between the two fixing rings.
[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) When the quartz sand in the filter tank needs to be replaced, simply lift the filter frame, separate the upper end of the side wall of the sedimentation tank from the slot, and the filter frame can be removed. Then pour out the quartz sand and replace it with new quartz sand. Finally, insert the upper end of the side wall of the sedimentation tank into the slot to complete the installation of the filter frame. The replacement of quartz sand is more convenient. (2) The water discharged from the fixed frame will enter the collection tank and then be discharged through the collection outlet. With the cooperation of the fixed frame and the collection plate, the drainage speed is faster than that of the existing technology. (3) The fixing plate can prevent the connecting plate from being completely removed from the fixing shaft, thereby preventing the screw from separating from the connecting mounting block and facilitating the use of the screw.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-6 This utility model provides a technical solution for a sedimentation tank for mud and water treatment.
[0017] A sedimentation tank for sludge treatment, comprising: The sedimentation tank body 1 has a sedimentation chamber 2 with its opening facing upwards. The sedimentation chamber 2 has an inlet 3 and an outlet trough 4 at its two ends, respectively. The filter frame 5 has an upward-facing filter groove 6. The filter groove 6 has a filter inlet groove 7 and a filter outlet groove 8 on opposite sides. The filter groove 6 is filled with quartz sand (or vermiculite or other filter particles). Both ends of the filter frame 5 are fixed with connecting mounting blocks 9. The connecting mounting blocks 9 have downward-facing slots 10. The upper end of the side wall of the sedimentation tank body 1 is inserted into the slots 10. The filter outlet groove 8 is connected to the effluent groove 4.
[0018] Both the inlet 3 and the outlet trough 4 are located at the upper end near the sedimentation chamber 2. The muddy water enters the sedimentation chamber 2 through the inlet 3 and accumulates at the bottom of the tank to form sludge. The clear liquid on the upper layer enters the filter tank 6 through the filter inlet 7, and then flows out from the filter outlet 8 and the outlet trough 4 after being filtered by quartz sand, thus serving as the function of filtering the outflowing water.
[0019] The filter frame 5 is installed on the sedimentation tank body 1 by connecting the mounting block 9. When the quartz sand in the filter tank 6 needs to be replaced, simply lift the filter frame 5, separate the upper end of the side wall of the sedimentation tank body 1 from the slot 10, and the filter frame 5 can be removed. Then, pour out the quartz sand and replace it with new quartz sand. Finally, insert the upper end of the side wall of the sedimentation tank into the slot 10 to complete the installation of the filter frame 5. The replacement of quartz sand is more convenient.
[0020] like Figure 3 and Figure 5 As shown, a fixed frame 11 is fixed to the side of the filter frame 5 facing away from the filter inlet 7, and the fixed frame 11 is inserted into the outlet trough 4. In this way, the water discharged from the filter outlet 8 is discharged through the fixed frame 11, which facilitates the collection of the discharged water.
[0021] like Figure 3 As shown, a collection plate 12 is fixed to the outer wall of the sedimentation tank body 1, located below the fixed frame 11. The collection plate 12 has an upward-facing collection trough 13, and the bottom of the collection trough 13 has a collection outlet 14. Water discharged from the fixed frame 11 enters the collection trough 13 and is then discharged through the collection outlet 14. Through the cooperation of the fixed frame 11 and the collection plate 12, the drainage speed is faster than that of the prior art.
[0022] like Figure 1 and Figure 3 As shown, a surrounding plate 15 is fixed to the upper end of the collecting plate 12. The surrounding plate 15 is in the shape of an "I". The opening of the surrounding plate 15 faces the fixed frame 11 to prevent water discharged from the fixed frame 11 from splashing out of the collecting tank 13.
[0023] like Figure 4 As shown below, one method of fixing the connecting mounting block 9 is described. The connecting mounting block 9 has a connecting hole 16 that communicates with the slot 10. The sedimentation tank body 1 has a threaded hole 17 corresponding to the connecting hole 16. A connecting bolt passes through the connecting hole 16 and is threadedly connected to the threaded hole 17. The connecting mounting block 9 is fixed to the sedimentation tank body 1 by the connecting bolt. When it is necessary to disassemble the filter frame 5, first unscrew the connecting bolt, then move the filter frame 5 laterally so that the fixed frame 11 moves out of the outlet tank 4, and then remove the filter frame 5.
[0024] like Figure 4 and Figure 6As shown, the connecting bolt includes a screw 18 and two retaining rings 19 fixed to the screw 18. A fixed shaft 20 corresponding to the connecting bolt is fixed on the connecting mounting block 9. A fixing plate 21 is fixed to the end of the fixing shaft 20 away from the connecting mounting block 9. The fixing shaft 20 is connected to a connecting plate 22. The two ends of the connecting plate 22 are respectively provided with a first connecting hole 23 and a second connecting hole 24. The fixing shaft 20 passes through the first connecting hole 23, and the screw 18 passes through the second connecting hole 24. The connecting plate 22 is located between the two retaining rings 19. When the screw 18 is screwed out of the threaded hole 17, the screw 18 rotates relative to the second connecting hole 24 of the connecting plate 22. The retaining rings 19 drive the connecting plate 22 to move outward until the screw 18 is completely removed from the threaded hole 17. The fixing plate 21 can prevent the connecting plate 22 from completely moving out of the fixing shaft 20, thereby preventing the screw 18 from separating from the connecting mounting block 9 and facilitating the use of the screw 18.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
