Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical sewage discharge treatment equipment, in particular to a water conservancy chemical sewage discharge treatment equipment. BACKGROUND

[0002] With the development of chemical industry, chemical products are various and complex in composition, and chemical sewage is the sewage discharged by chemical plants. The chemical sewage contains various organic acids, alcohols, aldehydes and epoxides, etc. Once this sewage is discharged into water, it will further oxidize and decompose in water, thereby consuming a large amount of dissolved oxygen in water and threatening the survival of aquatic organisms. Therefore, the sewage needs to be treated by equipment before being discharged.

[0003] At present, the equipment for treating chemical wastewater mostly neutralizes the sewage through a sedimentation tank, and then discharges the sediment and sundries in the neutralized sewage, so as to obtain relatively clean water. However, the equipment used in this process is usually large in size and occupies a large area. In addition, when filtering the sundries and sediment, a filtering device needs to be used, thereby increasing the cost of water treatment. SUMMARY

[0004] The present application provides a water conservancy chemical sewage discharge treatment equipment, which has the advantages of concentrated equipment size structure and high water treatment efficiency, and solves the problems in the above background technology.

[0005] The present application provides the following technical scheme: a water conservancy chemical sewage discharge treatment equipment, comprising a backwashing box, a water inlet box is fixedly installed on the left side of the backwashing box, a filter box is fixedly installed on the left side of the water inlet box, an overflow port is formed in the left side middle part of the water inlet box, overflow ports are formed in the top and left side middle part of the right side of the filter box, the overflow port in the left side middle part of the water inlet box is communicated with the overflow port in the top of the right side of the filter box, the filter box has three and is sequentially fixedly connected, the adjacent two filter boxes are communicated through the overflow ports, drive rollers are symmetrically movably sleeved in the inside of the backwashing box, annular filter cloths are movably installed in the inside of the water inlet box and the filter box and located in the left side overflow port, the annular filter cloths are movably sleeved with the drive rollers, the annular filter cloths are movably connected with the backwashing box, a water inlet is formed in the right side of the backwashing box, and a water outlet is formed in the bottom of the backwashing box and located on the left side of the annular filter cloth.

[0006] Preferably, turning rollers are symmetrically movably installed at the front and rear ends of the water inlet box and the filter box, the turning rollers are movably sleeved with the annular filter cloths, limit rollers are symmetrically movably installed in the inside of the water inlet box and the filter box, the limit rollers are movably connected with the annular filter cloths, the four annular filter cloths are arranged in a stacked manner from top to bottom, and the adjacent two annular filter cloths are movably connected.

[0007] Preferably, the two filter boxes located on the right side are provided with feed inlets. The bottom of the water inlet box and the filter box are at an angle of 10-15 degrees to the horizontal plane. The lowest point of the bottom of the water inlet box is fixedly connected to the discharge pipe. The discharge pipe is fixedly connected to the bottom of the filter box and a one-way valve is fixedly installed on the discharge pipe.

[0008] Preferably, a guide rail is fixedly installed inside the water inlet tank and the filter box and below the annular filter cloth. Contact rollers are evenly and movably engaged on the guide rail. The contact rollers are movably connected to the annular filter cloth. An impeller is fixedly connected to the bottom end of the contact roller and below the guide rail. A connecting chain is movably sleeved on the impeller. Two adjacent impellers are movably connected through the connecting chain.

[0009] The present invention has the following beneficial effects:

[0010] 1. Through the arrangement of the inlet tank, filter box, and annular filter cloth, sewage gradually flows into the filter box through the overflow port under the action of gravity. When passing through the overflow port, particulate impurities in the sewage are blocked by the annular filter cloth, which performs the first cleaning. The sewage then gradually flows through the three filter boxes, undergoing multiple filtrations through the annular filter cloth, finally obtaining clean wastewater, which is then discharged. After filtering impurities from the water, the annular filter cloth enters the backwashing box for backwashing to remove impurities adhering to the annular filter cloth, ensuring the cleanliness of the annular filter cloth, avoiding clogging, and preventing a reduction in filtration effect, thus ensuring the sewage filtration effect in the inlet tank and filter box.

[0011] 2. By setting up the contact roller and impeller, when the drive roller moves the annular filter cloth, the annular filter cloth comes into contact with the contact roller, which in turn drives the contact roller to rotate. Subsequently, the contact roller drives the impeller to rotate, and the impeller stirs the sewage in the inlet tank and filter box, thereby enhancing the reaction in the sewage and improving the sewage treatment efficiency. At the same time, it avoids excessive accumulation of sediment in one place in the inlet tank and filter box, which would cause it to adhere to the inside of the inlet tank and filter box, so that impurities can be smoothly discharged from the impurity outlet pipe.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-4A wastewater treatment device for water conservancy and chemical industries includes a backwash tank 1. An inlet tank 2 is fixedly installed on the left side of the backwash tank 1. A filter tank 3 is fixedly installed on the left side of the inlet tank 2. An overflow port is located in the middle of the left side of the inlet tank 2. Overflow ports are located at the top of the right side and the middle of the left side of the filter tank 3. The overflow port in the middle of the left side of the inlet tank 2 is connected to the overflow port at the top of the right side of the filter tank 3. There are three filter tanks 3, which are fixedly connected in sequence. Adjacent filter tanks 3 are connected through overflow ports. A drive roller 8 is symmetrically and movably fitted inside the backwash tank 1. An annular filter cloth 5 is movably installed inside the inlet tank 2 and the filter tank 3, located in the overflow port on the left side. The annular filter cloth 5 is movably fitted with the drive roller 8 and movably snapped into the backwash tank 1. An inlet 6 is located on the right side of the backwash tank 1, and an outlet 7 is located at the bottom of the backwash tank 1, to the left of the annular filter cloth 5. Chemical wastewater is introduced into the inlet tank 2, gradually increasing the inlet water... The wastewater is filled into tank 2. Under the action of gravity, the wastewater gradually flows into filter tank 3 through the overflow port. When passing through the overflow port, the particulate impurities in the wastewater are blocked by the annular filter cloth 5, which performs the first cleaning. Then the wastewater flows into filter tank 3 in sequence and passes through the annular filter cloth 5 for multiple filtrations. Finally, clean wastewater is obtained and then discharged. After filtering the impurities in the water, some of the impurities settle to the bottom of the inlet tank 2 and filter tank 3 under the action of gravity, while some remain on the annular filter cloth 5. Then, the drive roller 8 drives the annular filter cloth 5 to rotate, which brings the clogged annular filter cloth 5 to the backwash tank 1. By filling the inlet 6 with clean water, the annular filter cloth 5 is backwashed to remove the impurities adhering to the annular filter cloth 5, ensuring the cleanliness of the annular filter cloth 5, avoiding clogging, and preventing a reduction in filtration effect. This ensures the filtration effect of wastewater in inlet tank 2 and filter tank 3.

[0022] Both the front and rear ends of the water inlet tank 2 and the filter box 3 are symmetrically and movably equipped with guide rollers 16, which are movably connected to the annular filter cloth 5. The interiors of both the water inlet tank 2 and the filter box 3 are symmetrically and movably equipped with limit rollers 11, which are movably connected to the annular filter cloth 5. The guide rollers 16 guide the annular filter cloth 5, preventing excessive wear during movement. Simultaneously, when the annular filter cloth 5 is discharged from the overflow port, the limit rollers 11 limit and compress it, preventing excessive water leakage from the gaps. The four annular filter cloths 5 are stacked vertically, with adjacent annular filter cloths 5 movably connected. By stacking the four annular filter cloths 5, they are all uniformly rinsed in the backwash box 1. This allows for unified control of multiple filtration and backwashing processes, simplifying operation. To reduce water consumption, the equipment is streamlined and its footprint is reduced. Two filter boxes 3 on the right side have inlet ports 4. The bottoms of both the inlet tank 2 and the filter box 3 are at an angle of 10-15 degrees to the horizontal. A waste outlet pipe 9 is fixedly connected to the lowest point of the bottom of the inlet tank 2. The waste outlet pipe 9 is fixedly connected to the bottom of the filter box 3. A one-way valve 10 is fixedly installed on the waste outlet pipe 9. When wastewater flows into the filter box 3, neutralizing materials can be added through the inlet port 4 according to the composition of the chemical wastewater to remove pollutant molecules and generate sediment. The wastewater is then filtered again to clean it. Simultaneously, the one-way valve 10 can be opened to allow the sediment in the inlet tank 2 and the filter box 3 to flow out through the waste outlet pipe 9, preventing excessive sediment buildup in the inlet tank 2 and the filter box 3 and clogging of the annular filter cloth 5.

[0023] Please see Figures 5-7 Inside the inlet tank 2 and the filter box 3, and below the annular filter cloth 5, a guide rail 12 is fixedly installed. Contact rollers 13 are evenly and movably engaged on the guide rail 12. The contact rollers 13 are movably connected to the annular filter cloth 5. An impeller 14 is fixedly connected to the bottom of the contact roller 13 and below the guide rail 12. A connecting chain 15 is movably sleeved on the impeller 14. Two adjacent impellers 14 are movably connected through the connecting chain 15. When the drive roller 8 moves the annular filter cloth 5, the annular filter cloth 5 contacts the contact roller 13, thereby causing the contact roller 13 to rotate. At the same time, the contact roller 13 rotates on the guide rail 12. Then, the contact roller 13 drives the impeller 14 to rotate. The impeller 14 stirs the sewage in the inlet tank 2 and the filter box 3, thereby enhancing the reaction in the sewage and improving the sewage treatment efficiency. At the same time, it avoids excessive accumulation of sediment in one place in the inlet tank 2 and the filter box 3, which would cause it to adhere to the inside of the inlet tank 2 and the filter box 3 and affect subsequent cleaning.
