Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to acidic industrial wastewater purification treatment equipment. Background Art

[0002] Industrial wastewater, including production wastewater, production sewage and cooling water, refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater is of various types and complex in composition. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, it is necessary to develop comprehensive utilization and turn harm into benefit. According to the composition and concentration of pollutants in the wastewater, appropriate purification measures should be taken for disposal before it can be discharged. Acidic industrial wastewater often requires the use of multiple treatment equipment to remove slag, adjust pH, chemically precipitate, filter, disinfect, etc. to ensure that the wastewater meets the discharge standards. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN214693634U discloses an integrated device for filtering and purifying acidic industrial wastewater. The filter tank is provided with a water injection port at the upper right end, and a guide plate is provided below the water injection port. A filter screen is provided in the middle of the filter tank, and a sewage outlet is provided on the left side of the filter screen. A conveyor belt is installed at the upper left end of the filter screen, and a first scraper is provided on the outer surface of the conveyor belt, and a first motor is connected to the rear of the conveyor belt. The filter tank is connected to the sedimentation tank through the first pump body, and a servo motor is installed at the upper end of the sedimentation tank. Although the integrated device can perform multiple treatments at the same time, the filter tank, sedimentation tank, aggregate box, regulating tank, etc. are provided separately. In the sewage treatment process, the amount of sewage to be treated is large. The separately provided tanks greatly increase the space occupied by the equipment, which is not convenient for the reasonable layout of the space.

[0004] Purification equipment reduces its footprint by increasing its longitudinal length, but equipment that is too tall often makes it inconvenient for staff to perform internal cleaning and maintenance, increasing equipment maintenance costs. Utility Model Content

[0005] The purpose of the utility model is to provide an acidic industrial wastewater purification treatment equipment, which solves the problem that there are many types of treatment equipment and the space occupied by the equipment is greatly increased when they are set separately, while the problem that the equipment set vertically reduces the floor space is inconvenient to maintain when the equipment is too high, through the wastewater treatment tower and the filter box top cover.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an acidic industrial wastewater purification and treatment equipment, comprising a wastewater treatment tower, a filter box and a top cover. The filter box is slidably clamped in the wastewater treatment tower, a lifting cylinder is provided on the top of the filter box, an ultraviolet sterilization lamp is clamped and fixed in the filter box, a water-permeable oil filter component is clamped and fixed in the filter box, the top of the wastewater treatment tower is clamped and fixed, a liquid pump is clamped on the top of the top cover, and a delivery pipe is clamped through the top of the top cover;

[0008] The lifting cylinder can drive the filter box to move up and down, which is convenient for quickly removing the filter box when maintenance is needed. The filter box can filter solid debris and sediments produced by flocculation reactions, and the permeable oil filter component can filter the oil in the wastewater. The ultraviolet germicidal lamp can sterilize and disinfect the wastewater, so that the wastewater can be treated in multiple steps in a wastewater treatment tower, thereby improving the treatment efficiency. The wastewater treatment tower can be buried underground, and the treated water can be pumped out by a liquid pump, and the filtered filter residue can be pumped out by a delivery pipe, which is convenient for cleaning the inside and the structures required for maintenance of the treatment equipment are all located on the ground, thereby improving the convenience of maintenance operations, further reducing the space occupied by the equipment, and improving space utilization.

[0009] Furthermore, a water inlet pipe is connected through the top of one side of the wastewater treatment tower, a drug inlet pipe is welded through the top of the outer peripheral surface of the water inlet pipe, and a flow meter is connected through the outer peripheral surface of the water inlet pipe;

[0010] The flow meter can monitor the amount of wastewater passing through the water inlet pipe, and add an appropriate amount of flocculant through the drug inlet pipe according to the amount of wastewater, so that the wastewater can undergo sedimentation and flocculation reactions in the wastewater treatment tower.

[0011] Furthermore, a support plate is welded and fixed to the top of the filter box, a telescopic tube is slidably clamped on the bottom of the lifting cylinder, the bottom of the telescopic tube is clamped on the top of the support plate, a water suction pipe is welded through the top of the support plate, the water suction pipe is suspended from the top of the water-permeable oil filter assembly, the lifting cylinder is clamped on the top of the top cover, and the telescopic tube is inserted through the top of the top cover;

[0012] The lifting cylinder can drive the filter box to rise and fall in the wastewater treatment tower, so that when the wastewater undergoes flocculation reaction, the filter box is separated from the water surface, preventing the sediment from moving to the filter screen, thereby ensuring the treatment effect of the wastewater.

[0013] Furthermore, a filter screen is inserted through the bottom of the filter box, a first connecting hose is inserted through the top of the filter screen and the water-permeable oil filter assembly, and the top of the first connecting hose is inserted into one end of the water inlet pipe.

[0014] After the wastewater is poured into the inside of the wastewater treatment tower, flocculation reaction occurs between the wastewater and the flocculant. After a certain reaction time, the filter box is driven downward by the lifting cylinder to allow the flocculated wastewater to pass through the filter screen, while the solid waste residue and flocculated sediment are retained at the bottom of the filter screen. The oil in the wastewater is then filtered through the permeable oil filter component. The water passing through the permeable oil filter component is finally sterilized by an ultraviolet sterilization lamp, so that the treatment equipment can perform multiple wastewater treatment steps at the same time, thereby improving the wastewater treatment efficiency and reducing the volume of the treatment equipment.

[0015] Furthermore, the bottom of the filter box is fixed with a driving protection box on all sides, and a driving rod is inserted through the bottom of each driving protection box. The outer peripheral surface of the driving rod is clamped with a scraper, and the top of the scraper is attached to the bottom of the filter screen;

[0016] A driving motor is installed in the driving protection box, which can drive the rotation of the driving rod and the scraper to scrape off the particles blocked in the filter, avoid clogging of the filter, and ensure the efficiency of wastewater treatment.

[0017] Furthermore, a drainage pipe is inserted through the outer peripheral surface of the liquid pump, a second connecting hose is inserted through the bottom of the liquid pump, the second connecting hose is inserted through the top of the top cover, and one end of the second connecting hose is fixed to the top of the water pump;

[0018] After the wastewater has undergone multiple steps of treatment, the filtered water can be sucked out by a liquid pump and the water can be quickly extracted to facilitate the next step of processing of the treated water.

[0019] Furthermore, a sewage pipe is welded through the top of the outer circumference of the delivery pipe, a delivery motor is fixed to the top of the delivery pipe, a rotating rod is fixed to the bottom of the delivery motor, a spiral feeding assembly is fixed to the outer circumference of the rotating rod, the delivery pipe is inserted through the water-permeable oil filter assembly and the top of the filter screen, and the bottom of the delivery pipe is suspended at the bottom of the wastewater treatment tower;

[0020] After the treated water is pumped out, the conveying motor drives the rotating rod and the spiral conveying assembly to rotate, so that waste residue can enter the conveying pipe and be discharged through the sewage pipe. The structures required for maintenance of the treatment equipment are all located on the top cover, which is convenient for cleaning and maintenance. At the same time, the wastewater treatment tower can be buried underground, further reducing the space occupied by the equipment and improving space utilization.

[0021] The utility model has the following beneficial effects:

[0022] The utility model solves the problem that although the integrated equipment can carry out multiple treatments at the same time, the filter tank, sedimentation tank, aggregate box, regulating tank and the like are separately arranged, and in the sewage treatment process, the amount of sewage to be treated is large, and the separately arranged tanks greatly increase the space occupied by the equipment, which is not convenient for the reasonable layout of the space. The wastewater enters the wastewater treatment tower together with flocculants and other chemicals, and is placed and flocculated in the wastewater treatment tower. After a certain treatment time, the lifting cylinder drives the filter box to move slowly downward, so that the wastewater passes through the filter screen, and the sediment and impurities are retained at the bottom of the wastewater treatment tower. The wastewater is further blocked by the water-permeable oil filter component, and then the water is sterilized by the ultraviolet sterilization lamp, thereby completing multiple treatment steps for the wastewater, improving the treatment efficiency of the wastewater, and reducing the volume of the treatment equipment.

[0023] The utility model solves the problem that the purification treatment equipment reduces the floor space of the equipment by increasing the longitudinal length, but the equipment that is too high is often inconvenient for staff to perform internal cleaning and maintenance, which increases the maintenance cost of the equipment by arranging the wastewater treatment tower and the top cover. After the wastewater is treated, the water is pumped out by the liquid pump, and the rotation of the rotating rod and the spiral feeding assembly is driven by the conveying motor to make the waste residue enter the conveying pipe and be discharged through the sewage pipe. In addition, the structures required for maintenance of the treatment equipment are all located on the top cover, which is convenient for cleaning and maintenance, and the wastewater treatment tower can be buried underground, further reducing the occupied space of the equipment and improving space utilization.
