Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and more specifically, to a coal-water treatment device. Background Technology

[0002] Electrocoagulation devices are a type of coal-water treatment equipment and a key component of wastewater treatment. However, in actual use, the strong scouring force of the wastewater during influent can cause scouring of the inner wall of the device. Furthermore, the cleaning water used to clean the electrode plates can also cause scouring of the electrode plates, shortening their service life.

[0003] For example, CN215479932U discloses a coal-water treatment device, which includes a treatment tower with a cavity, an inlet pipe installed on the treatment tower, a diversion component installed in the cavity, a diversion pipe installed on the diversion component, an outlet pipe communicating with the cavity, and an electrode plate installed in the cavity.

[0004] As can be seen from the above-mentioned disclosed scheme, the sewage is diverted through the diversion pipe when it enters the water. Although this can prevent the sewage from directly washing the electrode plates, the sewage will still wash the inner wall of the treatment tower, causing damage and shortening its service life. Furthermore, when cleaning the electrode plates, the sewage inflow needs to be stopped, and then the surface of the electrode plates is washed with water sprayed through high-pressure nozzles. This makes cleaning the electrode plates not only time-consuming and laborious, but also causes damage to the surface of the electrode plates due to high-pressure water washing, shortening their service life and reducing the convenience and safety of cleaning. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a coal-water treatment device. This device, through the positioning rod, buffer plate, buffer spring, and buffer pad installed on the inlet pipe, can provide double buffering for the incoming sewage, thereby preventing the sewage from causing erosion and damage to the inner wall of the treatment tower and the electrode plates during water intake, thus avoiding shortening their service life. Furthermore, through the installed lead screw and brush plate, the surface of the electrode plates can be cleaned at any time without damaging the surface of the electrode plates, greatly improving the convenience and safety of cleaning.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0012] Furthermore, both the brush plate and the lead screw are made of insulating material, and the width of the brush plate is smaller than the distance between two adjacent electrode plates, so as not to affect the installation and operation of the electrode plates.

[0013] Furthermore, the water outlet is strip-shaped and distributed in an annular pattern at equal intervals, ensuring sufficient water output and that the discharged water is in contact with the surface of the buffer pad for cushioning.

[0026] Please see Figure 1-4A coal-water treatment device includes a treatment tower 1. The treatment tower 1 uses electrocoagulation to treat wastewater. Its working principle is well known to those skilled in the art and will not be described in detail here. The treatment tower 1 has an inlet pipe 2 and an outlet pipe 17 at its two ends, and a drain pipe 16 at its bottom. The surface of the inlet pipe 2 has an outlet hole 21 and a connecting hole 22. The outlet hole 21 is strip-shaped and evenly distributed in a ring to ensure the water output. The discharged water is in contact with the surface of the buffer pad 26 for buffering. The inner wall of the connecting hole 22 is threaded with a positioning rod 23. Buffer plates 24 are slidably sleeved on the two ends of the positioning rod 23 that pass through the inlet pipe 2. A buffer spring 25 is sleeved on the positioning rod between the end of the positioning rod 23 and the buffer plate 24. Buffer pads 26 are respectively provided on the opposing inner surfaces of the two buffer plates 24. Two partitions 1 are fixedly installed on the inner wall of the treatment tower 1. 1. A base frame 15 and a mounting plate 14 are provided. One partition 11 has an inlet 12 on its side and an outlet 13 on its surface. The small motor 4 is a reversible motor. The small motor 4 is fixedly installed on the side of the mounting plate 14. Multiple electrode plates 3 are arranged between the base frame 15, the mounting plate 14 and the two symmetrical partitions 11. When treating wastewater by electrocoagulation, the spacing between the electrode plates 3 in the device is between one and two centimeters. A liftable brush plate 43 is arranged between adjacent electrode plates 3. The width and length of the brush plate 43 can be set according to the actual length and spacing of the electrode plates 3. Soft bristles 44 are wrapped around the surface of the brush plate 43. Symmetrical lead rods 42 are threadedly connected to the top surface of the brush plate 43. Both the brush plate 43 and the lead rods 42 are made of insulating material. The width of the brush plate 43 is smaller than the spacing between two adjacent electrode plates 3, so as not to affect the installation and operation of the electrode plates 3.

[0027] Each lead screw 42 is fitted with two sealed bearings. The outer rings of the two sealed bearings are fixedly sleeved with the inner walls of the bearing holes provided on the mounting plate 14 and the base frame 15, respectively. The surface of the lead screw 42 is provided with external threads, and the brush plate 43 is provided with threaded holes. When the lead screw 42 rotates, it can drive the brush plate 43 to move up and down. The output end of the small motor 4 is provided with an output shaft, and the surface of the output shaft is fixedly sleeved with a sprocket 41. One end of the lead screw 42 is fixedly sleeved with a chain disc, and the chain disc is connected to the sprocket 41 through a transmission chain, so that the small motor 4 can synchronously drive multiple lead screws 42 to rotate in the same direction.

[0028] The buffer plate 24 has an arc-shaped cross-section and a sliding hole on its surface. The buffer pad 26 has a through hole on its surface that communicates with the sliding hole, so that the buffer plate 24 has a sliding buffer function. The inner wall of the through hole is in contact with the surface of the positioning rod 23. The buffer pad 26 is made of impact-resistant and corrosion-resistant buffer rubber. The buffer pad 26 not only has a buffer function, but also a damping function, preventing the buffer plate 24 from sliding randomly on the surface of the positioning rod 23.

[0029] In operation, wastewater enters the treatment tower 1 through the inlet pipe 2 and exits through the outlet 21. Upon exiting, the wastewater impacts the buffer pad 26 for cushioning, then pushes the buffer plate 24 to compress the buffer spring 25 for further cushioning. After this cushioning and release, the wastewater enters the electrode plate 3 through the inlet 12 for treatment. The treated wastewater exits the electrode plate 3 through the outlet 13 and then exits the treatment tower 1 through the outlet pipe 17. When cleaning the surface of the electrode plate 3 is required, the small motor 4 can be started to rotate clockwise, causing the lead screw 42 to rotate clockwise under the drive of the chain. This clockwise rotation of the lead screw 42 causes the brush plate 43 to be driven by the thread of the lead screw 42. When the brush plate 43 moves downward, the soft bristles 44 brush the dirt off the surface of the electrode plate 3. When the screw 42 rotates counterclockwise, the brush plate 43 moves upward to reset. The positioning rod 23, buffer plate 24, buffer spring 25 and buffer pad 26 set in the water inlet pipe 2 can provide double buffering for the incoming sewage, thereby avoiding the sewage from causing scouring and damage to the inner wall of the treatment tower 1 and the electrode plate 3 when entering the water, thus shortening their service life. In addition, the screw 42 and brush plate 43 can not only clean the surface of the electrode plate 3 at any time, but also prevent damage to the surface of the electrode plate 3, greatly improving the convenience and safety of cleaning.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
