Description

Technical Field

[0001] The utility model belongs to the technical field of thermal power plant equipment, and particularly relates to a chemical water treatment cleaning device for thermal power plants. Background Art

[0002] Chemical water treatment in thermal power plants is a crucial and complex process aimed at ensuring the safe and economic operation of thermal power plant equipment. The core of this treatment process is to remove impurities and harmful substances in water to prevent problems such as equipment scaling, corrosion, and salt accumulation. Therefore, in the initial process of chemical water cleaning, it is necessary to filter the impurities therein.

[0003] The utility model patent with the publication number CN219136406U discloses a chemical water treatment cleaning device for thermal power plants. The medicine inlet pipe can transport the liquid medicine into the chemical medicine cylinder, and then start the motor to drive the rotating rod to rotate, driving several stirring rods to stir the liquid medicine. After precipitation, the impurities in the liquid medicine are filtered through the filter cylinder, and then the liquid medicine is transported into the purification tank through the medicine outlet pipe for re - filtration. The liquid medicine is filtered multiple times through a pair of filter plates. At the same time, after long - term filtration, the filter plates need to be replaced. Pull a pair of filter plates, and when the pair of filter plates move, the limit wheels also move in the chute. At the same time, after manual cleaning is completed, when the chutes on both sides of the filter plate are engaged with the limit wheels, it is convenient to install the filter plate. Among them, the filter plate in the purification tank needs to be manually pulled out, and the filter screen is cleaned manually and reused, which is not automated enough, increasing the manual operation time and affecting the cleaning efficiency.

[0004] The utility model patent with the publication number CN215559427U discloses a chemical water treatment cleaning device for thermal power plants. When the adsorption net surface is blocked, the electric push rod works to drive the adsorption net at the bottom of the lifting plate to move upward above the filter box, and then rotate the adjusting wheel. When the adjusting wheel rotates, it drives the screw rod to rotate, driving the limit block to drive the motor box on the moving plate to approach the adsorption net. When the cleaning steel brush contacts the adsorption net, stop rotating the adjusting wheel. Finally, the motor works to drive the cleaning steel brush on the rotating disk to rotate, and the cleaning of the adsorption net can be completed, avoiding the trouble of manual cleaning and achieving the effect that the device can automatically clean the adsorption net. During this period, when the adsorption net moves upward above the filter box and the cleaning steel brush driven by the motor cleans the adsorption net, the sundries adhered to the filter screen will fall into the filter box. Secondly, only one side of the adsorption net is cleaned, and the adsorption net cannot be comprehensively cleaned, affecting the cleaning degree of the adsorption net. Utility Model Content

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0030] Embodiment 1

[0031] As Figure 1-2 shown, a chemical water treatment and cleaning device for a thermal power plant includes a processing tank 1 and a filter box 2. The upper part of the processing tank 1 is connected to the left end of the filter box 2 through a connecting pipe 3. The bottom of the processing tank 1 is integrally formed with an inverted hopper groove 12 of the processing tank. A first discharge valve 121 is installed at the bottom of the inverted hopper groove 12 of the processing tank. After the chemical water is precipitated in the processing tank 1, it is convenient to collect and accumulate the precipitates through the inverted hopper groove 12 of the processing tank, and it is convenient to discharge them through the first discharge valve 121. The chemical water that gets rid of most of the precipitates enters the filter box 2 through the connecting pipe 3 for filtration treatment.

[0032] Specifically, the filtering box 2 includes a filter plate placement groove 21, a filter plate 22, a lifting and rotating mechanism 23, a filter plate cleaning device 24, and a drain pipe 25. A filter plate placement groove 21 communicating with the interior is opened at the top of the filtering box 2. The filter plate 22 is placed in the filter plate placement groove 21, slidably connected up and down along the filter plate placement groove 21, and the outer wall is hermetically attached to the inner wall of the filtering box 2. An adsorption net is provided inside the filter plate 22 to prevent chemical water from flowing outside the filter plate 22. A lifting and rotating mechanism 23 is installed at the top of the filtering box 2 above the filter plate 22, and a filter plate cleaning device 24 is installed on the side. A drain pipe 25 is provided on the right side of the filtering box 2; the lifting and rotating mechanism 23 lifts and rotates the filter plate 22, and the filter plate 22 is cleaned by contacting the filter plate cleaning device 24.

[0033] Specifically, the lifting and rotating mechanism 23 includes a cylinder 231, a connecting ring 232, a rotating shaft 233, a connecting plate 234, a gear 235, a vertical rod 236, and a rack 237. The two cylinders 231 are symmetrically arranged on the left and right sides of the filter plate placement groove 21, and the stroke of the cylinder 231 should satisfy that the filter plate 22 is withdrawn from the filter plate placement groove 21. The bottom of the cylinder 231 is fixed to the filtering box 2. A connecting ring 232 is fixed to the telescopic end at the top of the cylinder 231. A rotating shaft 233 is connected between the two connecting rings 232. A connecting plate 234 is fixed to the middle of the rotating shaft 233. The end of the connecting plate 234 is fixed to the filter plate 22. Gears 235 are respectively fixed to both ends of the rotating shaft 233. Vertical rods 236 are respectively fixed beside the two cylinders 231. A rack 237 is integrally formed at the top of the vertical rod 236. The rack 237 meshes with the gear 235. The lowest end when the rack 237 meshes with the gear 235 should be higher than the position when the filter plate 22 is completely withdrawn from the filter plate placement groove 21. Moreover, the lifting height of the cylinder 231 and the length of the rack 237 should satisfy that the rotation angle of the gear 235 is between 60° and 180°;

[0034] The filter plate cleaning device 24 includes a brush support 241, a brush plate 242, and bristles 243. There are two brush supports 241, which are respectively fixed to the filtering box 2 at the left and right positions of the filter plate 22 to facilitate the filter plate 22 to pass through. A brush plate 242 is fixed to the top of the brush support 241. Bristles 243 are arranged on the opposite side of the brush plate 242. The bristles 243 should be on the rotation trajectory of the filter plate 22 to prevent the debris brushed off from falling into the filtering box 2. The bristles 243 on both sides can clean both sides of the filter plate 22, greatly strengthening the cleaning range of the filter plate 22. Moreover, through the lifting of the cylinder 231, two cleaning operations of the filter plate 22 are completed, increasing the cleaning efficiency of the filter plate 22.

[0035] Furthermore, a vertical limiting plate 211 is fixed to the filtering box 2 at the rear end of the top of the filter plate placement groove 21, so that when the filter plate 22 is reset, it can be prevented from swaying back and forth due to inertia, facilitating the filter plate 22 to be vertically inserted into the filter plate placement groove 21.

[0036] Further, a first solenoid valve 31 is provided in the middle of the connecting pipe 3, and a second solenoid valve 251 is provided at the end of the drain pipe 25. When the cylinder 231 is started, the first solenoid valve 31 and the second solenoid valve 251 are closed, so that the chemical water in the filter tank 2 is in a static state, avoiding the outflow of impurities inside the chemical water from the filter tank 2 due to the rising of the filter plate 22.

[0037] In the specific implementation process, the chemical water enters the treatment tank 1, and the sundries are deposited and accumulated in the inverted hopper groove 12 of the treatment tank and discharged through the first discharge valve 121. The chemical water in the upper part of the treatment tank 1 enters the filter tank 2 through the connecting pipe 3 and is filtered through the filter plate 22, and the sundries are adsorbed on the filter plate. The filtered chemical water is discharged through the drain pipe 25; when cleaning the filter plate 22, the first solenoid valve 31 and the second solenoid valve 251 are closed to stop the water flow in the filter tank 2 and keep it in a static state. The cylinder 231 is started to vertically lift the filter plate 22 and slide upward from the filter plate placement groove 21. When the filter plate 22 is completely pulled out of the filter plate placement groove 21, the gear 235 contacts the rack 237 for transmission. The gear 235 rotates the rotating shaft 233 along the connecting ring 232, and drives the filter plate 22 to rotate through the connecting plate 234. During the rotation of the filter plate, it passes between the two brush plates 242 and contacts the bristles 243. The bristles 243 initially clean both sides of the filter plate 22. When the cylinder 231 descends, the bristles 243 clean both sides of the filter plate 22 again. When the gear 235 disengages from the rack 237, the rear side of the filter plate 22 contacts the limiting plate 211 to prevent the filter plate 22 from shaking. At this time, the filter plate 22 moves vertically downward and is inserted into the filter tank 2 from the filter plate placement groove 21 for repeated filtration use. Then the first solenoid valve 31 and the second solenoid valve 251 are opened to continue the chemical water treatment operation. Only by the lifting of the cylinder, the cleaning work of the filter plate 22 is completed efficiently and fully automatically, saving manual labor, accelerating the cleaning efficiency of the filter plate, and also preventing the sundries from falling into the filter tank 2 during cleaning.

[0038] Embodiment 2

[0039] In order to facilitate the collection and cleaning of the sundries blocked on the left side of the filter plate 22 in the filter tank 2 and prevent them from accumulating under the filter plate 22 and causing blockage, an improvement is made on the basis of Embodiment 1, as Figure 3 shown. In this embodiment, a filter tank inverted hopper groove 28 is integrally formed at the bottom of the filter tank 2 on the left side of the filter plate 22, and a second discharge valve 281 is installed at the bottom of the filter tank inverted hopper groove 28.

[0040] In the specific implementation process, the sundries not adsorbed by the filter plate 22 are collected in the filter tank inverted hopper groove 28 through precipitation. When they accumulate to a certain extent, they are discharged through the second discharge valve 281 to prevent the sundries from blocking the filter plate 22 and affecting the filtering effect.

[0041] Example 3

[0042] To improve the cleaning degree of the filter plate 22 and to be able to clean the sundries adhered to the bristles 243, it is improved on the basis of Example 2. As Figure 4-5 shown, in this embodiment, a water spraying device 26 is provided at the top of the brush plate 242. The water spraying device 26 includes a water spraying pipe 261, a connector 262, and a nozzle 263. The water spraying pipe 261 is fixed to the brush plate 242. A connector 262 is provided on the outer side of the water spraying pipe 261 for connecting a water pump. A nozzle 263 is provided on one side of the connector 262 close to the bristles 243. The spraying range of the nozzle 263 includes the bristles 243 and the gap between the left and right bristles 243 on both sides.

[0043] In the specific implementation process, when the air cylinder 231 is started, the water pump supplies water to the water spraying pipe 261 through the connector 262, and the nozzle 263 cleans the bristles 243. When the filter plate 22 passes between the bristles 243, the nozzle 263 also cleans the filter plate 22, which combines with the bristles 243 to enhance the cleaning effect of the filter plate 22 and can also keep the bristles 243 clean, facilitating the next cleaning use of the bristles 243.

[0044] Example 4

[0045] To enable the sewage washed by the nozzle 263 from the bristles 243 and the filter plate 22 to be collected and treated, it is improved on the basis of Example 3. As Figure 4 shown, in this embodiment, the filter tank 2 further includes a sewage basin 27. The sewage basin 27 is fixed to the filter tank 2 directly below the water spraying device 26. A leakage hole 271 is opened in the middle of the sewage basin 27.

[0046] In the specific implementation process, the sewage washed by the nozzle 263 from the bristles 243 and the filter plate 22 falls into the sewage basin 27, enabling the sewage to be centrally collected, avoiding subsequent manual cleaning operations, and discharging the sewage centrally through the leakage hole 271.

[0047] Example 5

[0048] To accelerate the precipitation efficiency of the chemical water impurities in the treatment tank 1 and also reduce the subsequent filtration burden of the filter plate 22, it is improved on the basis of Example 4. As Figure 6-7As shown in the figure, in this embodiment, the treatment tank 1 further includes a stirring device 13. The stirring device 13 includes a motor 131, a stirring shaft 132, and stirring rods 133. The motor 131 is fixed at the center of the top of the treatment tank 1. The stirring shaft 132 is located at the axial center position inside the treatment tank 1 and is connected to the output end of the motor 131 at the top. A plurality of stirring rods 133 are fixed on the stirring shaft 132. By the rotation of the stirring rods 133, the chemical water and the liquid medicine are fully mixed, and the precipitation effect of impurities in the chemical water is accelerated.

[0049] Furthermore, a preliminary filter screen 32 is fixed inside the treatment tank 1 at the left end of the connecting pipe 3 to play a preliminary filtering role. A rotary cleaning device 14 is provided at the end of the stirring rod 133 at the same horizontal position as the preliminary filter screen 32. The rotary cleaning device 14 includes a rotary plate 141 and rotary bristles 142. The rotary plate 141 is fixed at the end of the stirring rod 133 at a corresponding height to the preliminary filter screen 32. The rotary bristles 142 are arranged on the rotary plate 141 on the opposite side to the preliminary filter screen 32. Every time the stirring rod 133 rotates one circle, the rotary bristles 142 will clean the preliminary filter screen 32 once.

[0050] During the specific implementation process, the motor 131 is started to drive the stirring rods 133 to rotate, so as to fully mix the chemical water and the liquid medicine, make the impurities in the chemical water flocculate and precipitate. The chemical water passes through the preliminary filter screen 32 and enters the connecting pipe 3. The preliminary filter screen 32 plays a role in blocking the sundries in the chemical water, reducing the sundries entering the filter box 2 and reducing the burden on the filter plate 22. And the stirring rods 133 can drive the rotary cleaning device to rotate through rotation. Among them, the rotary bristles 142 can clean the preliminary filter screen 32 to avoid blockage, facilitate the continuous use of the preliminary filter screen 32, and do not require manual cleaning.

[0051] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
