Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dirt collection devices for water treatment, and particularly relates to a bottom dirt collection device for a neutralization tank for treating acidic wastewater. Background Technique
[0002] The neutralization method is the most commonly used water treatment process for leaching residues in China. Its principle is to add alkaline substances, such as lime milk, caustic soda, etc., to the wastewater, and by increasing the pH of the system, the heavy metal substances in the wastewater are removed by hydroxide precipitation and carbonate precipitation.
[0003] Currently, during the process of treating acidic wastewater using the chemical precipitation method, a large amount of lime needs to be added to maintain the pH of the front-end pretreatment and form flocs in the thickener for rapid sedimentation. During the AMD neutralization treatment process, a large amount of iron deposits and CaSO4 generated by the reaction are coated on the surface of lime particles, restricting the further dissolution and release of lime, resulting in a large amount of waste. The amount of lime used in the lime neutralization method is relatively large during the treatment process, and it is easy to form silt at the bottom, which needs to be cleaned and collected in a timely manner.
[0004] The existing cleaning and collection equipment is cumbersome during the operation process, and during the collection process, it cannot be flexibly adjusted according to the hardness of the sediment and the height of the sediment, which affects the cleaning and collection efficiency.
[0005] Based on this, a bottom dirt collection device for a neutralization tank for treating acidic wastewater is proposed. Content of the Utility Model

[0016] The present invention has the following advantages compared with the prior art:
[0017] 1. The utility model can complete the collection operation of the dirt at the bottom of the entire pool body through the rotation of the lead screw. A lead screw is installed longitudinally in the top frame at the opening on the top surface of the neutralization pool body for water treatment. The longitudinal axis of the top frame corresponds to the longitudinal axis of the pool body opening, and the length of the lead screw is not less than the length of the long axis of the pool body opening.

[0019] 3. When the utility model is used, the top frame is first installed at the opening of the top surface of the pool body, and the direction of the screw is parallel to the long axis of the pool body. Then, according to the thickness of the dirt at the bottom of the pool body, the length of the hydraulic cylinder is roughly adjusted so that the bottom of the collecting mechanism is against the highest point of the dirt deposition. Then, the screw motor is used to drive the screw to rotate so that the tail end of the dirt collecting port of the collecting mechanism is against the inner wall of the pool body. Then, the adjustment cylinder is started so that the adjustment cylinder drives the movable plate to descend to a set height, which is the opening height of the dirt collecting port. At this time, the movable plate descends to the depth in the dirt. Then, the screw motor is used to drive the screw to rotate. During the rotation, the head end of the dirt collecting port is controlled to move forward. During the movement, the dirt on the movable plate can enter the dirt collecting bag body through the dirt collecting port, thereby completing a single layer. Dirt collection: After a single layer of collection is completed, observe the amount of dirt in the dirt collection bag. If the amount of dirt reaches the maximum collection capacity of the dirt collection bag, use the hydraulic cylinder to lift up the dirt collection bag to complete a single dirt collection operation. If the amount of dirt does not reach the maximum collection capacity of the dirt collection bag, use the hydraulic cylinder to separate the dirt collection bag from the top surface of the dirt, then control the screw motor to drive the screw to rotate in the opposite direction until the collection mechanism is reset, and then use the hydraulic cylinder to descend again until the movable plate descends into the dirt, and repeatedly use the screw rotation to drive the collection mechanism to move and collect, and repeat until the amount of dirt in the dirt collection bag reaches the maximum collection capacity of the dirt collection bag, completing a single dirt collection operation, and repeat the above operation process until the dirt on the bottom surface of the pool body is completely collected, which is convenient and practical.

[0024] 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.
[0025] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a bottom dirt collection device for an acid wastewater treatment neutralization tank, comprising a tank body 1 and a top frame 2 installed at an opening on the top surface of the tank body 1;
[0026] The top frame 2 is specifically a rectangular frame, the long axis of the top frame 2 corresponds to the long axis of the opening of the pool body 1, and the length of the screw 21 is not less than the long axis length of the opening of the pool body 1, so that the collection operation of the dirt 11 at the bottom of the entire pool body 1 can be completed by rotating the screw 21.
[0027] A lead screw 21 is installed in the long axis direction inside the top frame 2, and a lead screw motor 23 for driving the lead screw 21 to rotate is also installed outside the top frame 2. A threaded barrel 22 is threadedly connected to the outer side of the lead screw 21, and a hydraulic cylinder 24 is fixed to the bottom end of the threaded barrel 22. A collecting mechanism 3 is vertically fixed to the bottom end of the hydraulic cylinder 24. Limiting grooves 26 parallel to the lead screw 21 are also fixed on both sides of the lead screw 21 inside the top frame 2, and a limiting rod 25 is movably connected inside the limiting groove 26. The bottom end of the limiting rod 25 is also fixed on the collecting mechanism 3. The rotation of the screw motor 23 can drive the screw 21 to rotate. The rotation of the screw 21 can drive the threaded barrel 22 to work. Under the longitudinal restriction of the limiting rod 25 and the limiting groove 26, the threaded barrel 22 moves along the screw 21 on the outside of the screw 21, thereby driving the collecting mechanism 2 at the bottom of the threaded barrel 22 to move in the long axis direction of the pool body 1, so that the dirt 11 at the bottom of the pool body 1 can be collected by the collecting mechanism 3.
[0028] During the collection process, the hydraulic cylinder 24 can be raised and lowered to collect dirt at different heights. In order to prevent the collection mechanism 3 from slipping during the lifting and adjustment process, an anti-slip block 27 is fixed to the top of the limit rod 25, and the length of the limit rod 25 is not less than the depth of the pool body 1.
[0029] The collecting mechanism 3 includes a fixed plate 31, an adjusting cylinder 32 and a movable plate 33. The fixed plate 31 is fixed to the bottom end of the telescopic rod of the hydraulic cylinder 24. The two side ends of the fixed plate 31 are vertically fixed with adjusting cylinders 32. The telescopic axis of the adjusting cylinder 32 extends to the bottom end of the fixed plate 31. The movable plate 33 is fixed to the bottom end of the telescopic axis of the adjusting cylinder 32, so that the relative distance between the fixed plate 31 and the movable plate 33 can be adjusted by adjusting the extension and retraction of the adjusting cylinder 32, so that the opening size of the dirt collection port of the collecting mechanism 3 can be adjusted.
[0030] Specifically, the cross-sections of the fixed plate 31 and the movable plate 33 are both triangular. The fixed plate 31 and the movable plate 33 are arranged oppositely to form a dirt collection port, and the tip of the triangle is arranged at the head end of the dirt collection port, which is conducive to cutting and collecting the dirt 11 layer by layer.
[0031] The opening area of the head end of the dirt collection port is larger than the opening area of the tail end of the dirt collection port. A dirt collection bag body 4 is also installed in the collection mechanism 3, and the dirt collection bag body 4 is installed at the tail end of the dirt collection port, so that the cut dirt can enter the dirt collection bag body 4 through the dirt collection port, completing the dirt collection operation.
[0032] The dirt collection bag body 4 is a low-elastic mesh bag body. A plurality of mounting buckles are evenly fixed at the tail ends of the fixed plate 31 and the movable plate 33. The top end of the opening of the dirt collection bag body 4 is clamped on the fixed plate 31, and the bottom end of the opening of the dirt collection bag body 4 is clamped on the movable plate 33. The clamping connection between the dirt collection bag body 4 and the fixed plate 31 and the movable plate 33 is completed through the mounting buckles. The snap connection is conducive to the installation and disassembly operations between the dirt collection bag body 4 and the collection mechanism 3, and is convenient for the collection mechanism 3 to adaptively adjust when adjusting the opening size of the dirt collection port through the fixed plate 31 and the movable plate 33, avoiding the tearing phenomenon of the dirt collection bag body 4 and improving the efficiency of the dirt collection operation.
[0033] In summary, when in use, first install the top frame 2 at the opening on the top surface of the pool body 1, with the lead screw 21 facing parallel to the long axis direction of the pool body 1. Then, according to the thickness of the dirt 11 at the bottom of the pool body 1, roughly adjust the length of the hydraulic cylinder 24 so that the bottom of the collection mechanism 3 abuts against the highest point where the dirt 11 is deposited;
[0034] Then drive the lead screw 21 to rotate by the lead screw motor 23, so that the tail end of the dirt collection port of the collection mechanism 3 abuts against the inner wall of the pool body 1. Then start the adjustment cylinder 32 to drive the movable plate 33 to descend by a set height, which is the opening height of the dirt collection port. At this time, the movable plate 33 descends to this depth in the dirt 11. Then drive the lead screw 21 to rotate by the lead screw motor 23. During the rotation, control the head end of the dirt collection port to move forward. During the movement, the dirt 11 on the movable plate 33 can enter the dirt collection bag body 4 through the dirt collection port, thus completing the collection of a single layer of dirt 11;
[0035] After the single-layer collection is completed, observe the amount of dirt in the dirt collection bag body 4. If the amount of dirt reaches the maximum collection amount of the dirt collection bag body 4, use the hydraulic cylinder 24 to rise and pull up the dirt collection bag body 4 to complete a single dirt collection operation;
[0036] When the amount of dirt does not reach the maximum collection amount of the dirt collection bag body 4, the hydraulic cylinder 24 is used to lift the dirt collection bag body 4 away from the top surface of the dirt 11, and then the lead screw motor 23 is controlled to drive the lead screw 21 to rotate in the reverse direction until the collection mechanism 3 is reset. Then, the hydraulic cylinder 24 is used again to lower until the movable plate 33 descends into the dirt 11. The lead screw 21 is repeatedly rotated to drive the collection mechanism 3 to move and collect. This is repeated until the amount of dirt in the dirt collection bag body 4 reaches the maximum collection amount of the dirt collection bag body 4, and the single dirt collection operation is completed.
[0037] Repeat the above operation process until the dirt on the inner bottom surface of the pool body 1 is completely collected, which is convenient and practical.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
