[0002] When maintaining coal washing equipment, the cleaning liquid after cleaning it contains a large amount of particulate matter and harmful substances. Its water quality is different from that of general urban sewage, with characteristics such as large changes in water quality and quantity, poor biodegradability of sewage, and difficulty in natural sedimentation. If directly discharged, it will not only pollute water bodies and silt up river channels, but also harm the growth of aquatic organisms. Therefore, a filter device for the cleaning liquid of coal washing equipment is needed to filter the waste liquid generated by cleaning before discharging.

[0003] After the filter device for the cleaning liquid of coal washing equipment has been filtering for a long time, a large amount of particulate matter and waste residue are likely to accumulate on the filter screen. However, most of the current filter mechanisms of the filter devices for the cleaning liquid of coal washing equipment on the market are too simple in design, making it inconvenient to clean the particulate matter and waste residue accumulated on the filter screen, easily causing the filter screen to be blocked, resulting in a gradual deterioration of the filtering effect, affecting the filtering quality and the normal progress of the filtering work. For this reason, we provide a filter device for the cleaning liquid of coal washing equipment to solve the above problems. Content of the Utility Model

[0021] See Figures 1 to 4, A cleaning liquid filtering device for coal washing equipment, including a filtering box 1 and a knocking mechanism 2. The knocking mechanism 2 is installed on the right side of the filtering box 1. The knocking mechanism 2 includes a mounting frame 201. The mounting frame 201 is fixedly connected to the right side of the filtering box 1. A first motor 202 is fixedly connected inside the mounting frame 201.

A worm gear 206 is meshed on the surface of the worm 204. A third rotating shaft 207 is fixedly connected to the left side of the worm gear 206. The left end of the third rotating shaft 207 penetrates through the right side of the filtering box 1 and extends into the filtering box 1. A semi-crown gear 208 is fixedly connected to the left end of the third rotating shaft 207. A fixing frame 209 is arranged on the left side of the semi-crown gear 208. A fourth rotating shaft 210 is rotatably connected inside the fixing frame 209. A gear 211 is fixedly connected to the surface of the fourth rotating shaft 210.

A spring 213 is fixedly connected to the side of the knocking rod 212.

[0022] By controlling the switch 10 to operate the first motor 202, under the cooperation of the worm 204 and the worm gear 206, the semi-crown gear 208 is driven to rotate. Under the cooperation of the semi-crown gear 208, the gear 211 and the spring 213, the knocking rod 212 is driven to knock on the fixing plate 3, causing the filter screen 12 to vibrate, so that the accumulated particulate matter and waste residues are quickly discharged under the cooperation of the inclined filter screen 12 and the opened sealing door 6, thereby cleaning the filter screen 12. This setting is more convenient for cleaning the particulate matter and waste residues accumulated on the filter screen 12, avoiding blockage of the filter screen 12, preventing the filtering effect from gradually deteriorating, effectively improving the filtering quality, and avoiding affecting the normal progress of the filtering work.

[0023] A fixing plate 3 is fixedly connected inside the filtering box 1. A filter screen 12 is fixedly connected inside the fixing plate 3. The upper end of the fixing frame 209 is fixedly connected to the bottom surface of the fixing plate 3. The upper end of the spring 213 is fixedly connected to the bottom surface of the fixing plate 3.

[0024] The setting of the filter screen 12 can filter the cleaning liquid, filter out the particulate matter and waste residues in the cleaning liquid, and avoid affecting the discharge.

[0025] Inside the filtering box 1, a stirring mechanism 5 is installed. The stirring mechanism 5 includes a motor housing 501 which is fixedly connected to the bottom of the filtering box 1. Inside the motor housing 501, a second motor 502 is fixedly connected. The output end of the second motor 502 is fixedly connected to a fifth rotating shaft 503. The upper end of the fifth rotating shaft 503 penetrates through the bottom of the filtering box 1 and extends into the interior of the filtering box 1. The upper end of the fifth rotating shaft 503 is fixedly connected to a rotating rod 504, and stirring rods 505 are fixedly connected to the surface of the rotating rod 504.

[0026] By controlling the switch 10 to operate the second motor 502, with the cooperation of the rotating rod 504 and the stirring rods 505, it is more conducive to the full mixing of the cleaning liquid and the disinfectant, greatly improving the disinfection effect of the filtered cleaning liquid and accelerating the disinfection efficiency of the cleaning liquid.

[0027] The upper surface of the filtering box 1 is fixedly connected with a feed hopper 4. The left side of the filtering box 1 is movably connected with a sealing door 6. The lower part on the left side of the filtering box 1 is fixedly connected with a discharge port 7, and a valve 8 is fixedly connected to the surface of the discharge port 7.

[0028] The feed hopper 4 makes it more convenient for the cleaning liquid to enter the interior of the filtering box 1. The setting of the valve 8 and the discharge port 7 makes it more convenient to discharge the filtered and disinfected cleaning liquid.

[0029] The right side of the filtering box 1 is fixedly connected with a storage box 13. An electromagnetic valve 14 is installed inside the right side of the filtering box 1. An observation window 9 is opened on the front side of the filtering box 1, and a control switch 10 is fixedly connected to the front side of the filtering box 1.

[0030] By controlling the switch 10 to open the electromagnetic valve 14, it is more convenient for the disinfectant in the storage box 13 to flow into the bottom inside the filtering box 1. The setting of the control switch 10 facilitates people to control the operation of the device.

[0031] The bottom surface of the filtering box 1 is fixedly connected with support legs 11. There are four groups of support legs 11, and the four groups of support legs 11 are respectively distributed in a rectangular shape at the bottom of the filtering box 1.

[0032] The setting of the support legs 11 can provide stable support for the device, improving the stability of the overall device during operation.

[0033] Working principle: When using this device, the solenoid valve 14 is opened by controlling the switch 10, so that the disinfectant in the storage box 13 flows into the bottom of the filter box 1. The cleaning liquid is poured into the filter box 1 through the feed hopper 4 and filtered through the filter net 12. When the filtered cleaning liquid enters the bottom of the filter box 1, the second motor 502 is controlled to operate by the control switch 10. With the cooperation of the rotating rod 504 and the stirring rod 505, the cleaning liquid and the disinfectant are fully mixed to disinfect the cleaning liquid. Then, the valve 8 is opened to discharge the disinfected cleaning liquid. When it is observed through the observation window 9 that there are too many particles and waste residues accumulated on the surface of the filter net 12, the filtration of the cleaning liquid is stopped. Then, the sealing door 6 is opened, and the first motor 202 is controlled to operate by the control switch 10. With the cooperation of the worm 204 and the worm gear 206, the semi-crown gear 208 is driven to rotate. The semi-crown gear 208 drives the gear 211 to rotate, thereby driving the knocking rod 212 to move downward to stretch the spring 213. When the semi-crown gear 208 rotates to a position where it is no longer engaged with the gear 211, the pulling force of the spring 213 drives the knocking rod 212 to move upward, thereby knocking on the fixing plate 3 to vibrate the filter net 12. As a result, the accumulated particles and waste residues are quickly discharged under the cooperation of the inclined filter net 12 and the opened sealing door 6, thus cleaning the filter net 12.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
