Technical Field

[0001] The utility model relates to the field of chemical waste liquid treatment equipment, in particular to a chemical waste liquid pretreatment device. Background Art

[0002] Chemical waste liquid is the waste liquid generated during the production process of the chemical industry, usually containing various organic substances, inorganic substances, solvents, heavy metals, acids and alkalis, etc. These substances have dangerous characteristics such as toxicity, corrosiveness, flammability, and explosiveness, posing potential hazards to the environment and human health.

[0003] After retrieval, the existing Chinese patent (Publication No.: CN212632052U) discloses a chemical waste liquid pretreatment device, including a box body, a first filter layer, a second filter layer and an extrusion device; attached to the bottom of the second filter layer, a liquid guide pipe is arranged on the box body; one end of the liquid guide pipe is attached to the bottom of the second filter layer, and the other end passes through the box body and extends to the outside of the box body; the utility model can filter out all solid impurities in the chemical waste liquid and then discharge the other relatively normal pure liquid chemical waste liquid to the purification equipment for further purification, which not only makes the purification of the chemical waste liquid more thorough, but also does not damage the purification device for purifying the waste liquid.

[0004] The above waste liquid pretreatment device solves the technical problem that the existing waste liquid treatment is not thorough enough by filtering through a sponge and adsorbing certain harmful substances, and then extruding the sponge through a pressing plate to discharge the harmful liquid from the liquid guide pipe. As time goes by, the sponge of the second filter layer will be blocked by solid impurities and harmful substances, thus affecting the filtering efficiency. Therefore, we propose a chemical waste liquid pretreatment device to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a chemical waste liquid pretreatment device, which solves the technical problem that the sponge of the filter layer of the existing waste liquid pretreatment device will be blocked by solid impurities and harmful substances after long-term use, thus affecting the filtering efficiency.

[0006] To solve the above technical problem, a chemical waste liquid pretreatment device provided by the utility model includes a box body and a fixing block, a pushing component is fixedly connected to the top end of the fixing block, and a cleaning component is fixedly connected to one side of the top end of the fixing block away from the pushing component;

[0007] The pushing component includes a hydraulic cylinder, a push plate, positioning blocks, a sponge, and a funnel. The bottom end of the hydraulic cylinder is installed on a fixed block. One end of the push plate is fixedly connected to the driving end of the hydraulic cylinder, and the other end of the push plate is fixedly connected to the sponge. Both sides of the push plate are slidably connected to the positioning blocks. The far sides of the two positioning blocks are fixedly connected to the box body. Both sides of the sponge are slidably connected to the near sides of the two positioning blocks. The outer side of the funnel is fixedly connected to the inner wall of the box body.

[0008] Adopting the above technical solution: The box body provides overall support and protection, while the fixed block undertakes the role of fixing other components. The design of the pushing component enables the push plate to smoothly push the sponge to work. The push plate is connected to the driving end of the hydraulic cylinder to ensure that the power of the hydraulic cylinder can be effectively transmitted to the push plate. The push plate can stably move back and forth. The push plate is firmly fixed to the sponge, enabling the force of the push plate to compress the sponge. Subsequently, the push plate moves smoothly back and forth under the guidance of the positioning blocks, avoiding the situation of deviation or jamming during the pushing process. The positioning blocks fixed on the box body provide a stable movement track for the push plate. The sponge slides on the positioning blocks, enabling the sponge to maintain smooth movement under the guidance of the positioning blocks, ensuring the smooth progress of the cleaning work. The design of the funnel can be firmly fixed inside the box body, providing an effective diversion channel for the cleaning work and ensuring the smooth discharge of the cleaning liquid.

The connection between the water tank and the fixed block guarantees the firm installation of the water tank. The shunt pipe is connected to the output end of the water pump, enabling water to be output from the water pump and smoothly shunted to other components, improving the utilization efficiency of water. The input end of the water pump is connected to the water tank, ensuring that the water pump can stably obtain water from the water tank. The infusion pipe is connected to the shunt pipe, prompting the water flow to flow from the shunt pipe to other components, realizing the transportation and distribution of the water flow. The other end of the shunt pipe is connected to the water outlet, ensuring that the water can be effectively sprayed onto the area to be cleaned, improving the cleaning efficiency and accuracy.

The liquid guide plate is firmly fixed at the bottom of the box body, making the liquid guide plate a guide for liquid flow and helping the liquid to be discharged from the box body smoothly. The positioning plates can be firmly connected to both sides of the top end of the fixed block, providing stable support and positioning for the pushing assembly.

[0013] Preferably, both sides of the box body away from the liquid inlet are fixedly connected with support plates, and a sliding door is slidably connected to the adjacent side of the two support plates.

The connection of the bottom end of the water pump 301 to the fixed block 5 ensures the stability of the water pump 301, enabling the water pump 301 to effectively provide water flow. The connection of the water tank 302 to the fixed block 5 ensures the firm installation of the water tank 302. The connection of the shunt pipe 303 to the output end of the water pump 301 allows water to be output from the water pump 301 and smoothly shunted to other components, improving the utilization efficiency of water. The connection of the input end of the water pump 301 to the water tank 302 ensures that the water pump 301 can stably obtain water source from the water tank 302.

[0035] As Figure 1 - Figure 2As shown, one end of the positioning plate 7 away from the fixed block 5 is fixedly connected to the outside of the shunt pipe 303. One side of the sliding door 9 close to the liquid inlet 306 is slidably connected to the box body 1.

The polypropylene material has good wear resistance and corrosion resistance and can maintain stability in a humid environment.

[0036] Working principle: As Figure 1 - Figure 4 shown, first, the waste liquid to be processed is poured into the box body 1 from the funnel 205. The funnel 205 conducts preliminary filtration to filter out larger particles, and then the waste liquid flows onto the sponge 204 under the guidance of the inclined plate 4. The sponge 204 filters out harmful substances in the waste liquid, and finally the liquid flows out from the liquid guide plate 6. After the liquid filtration is completed, at this time, the hydraulic cylinder 201 receives a control signal, starts and applies pressure to push the push plate 202 forward. The push plate 202 slides on the positioning block 203, and the positioning block 203 ensures the stable movement track of the push plate 202. Then, the sponge 204 is pushed forward to be squeezed, and the filtered liquid is squeezed out of the sponge 204 and collected by the liquid guide plate 6 for these harmful liquids. When the sponge 204 needs to be replaced, pull the sliding door 9. When the hydraulic cylinder 201 drives the push plate 202 to push the sponge 204, it can be pushed out from the sliding door 9 to replace the sponge 204. Secondly, the water tank 302 is filled through the liquid inlet 306, and then the water pump 301 is started. The cleaning liquid in the water tank 302 is transported to the water outlet 305 through the infusion pipe 304 and the shunt pipe 303, and the cleaning liquid can be evenly sprayed on the area to be cleaned. The water flow cleans the inside of the box body 1 along the flow direction of the waste liquid.
