Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater filtration tanks, specifically relating to a wastewater filtration tank for environmental engineering. Background Technology

[0002] Wastewater filtration tanks in environmental engineering are devices that effectively remove suspended solids from wastewater. Typically, a filtration tank contains multiple layers of filter media, usually separated by mesh. When wastewater enters the tank, different filter layers trap impurities of varying diameters, thus removing them and purifying the water. However, when a large amount of impurities accumulates in the filter layers and gradually occupies the pores, it can increase the resistance to water flow, reducing filtration efficiency. To avoid this, it is generally necessary to clean the impurities inside the filtration tank.

[0003] However, most existing cleaning methods only remove impurities located at the top of the separator. While this method can reduce clogging caused by impurity deposition to some extent, it cannot effectively remove impurities in the filter media within the filter layer. This causes impurities in the filter layer to gradually accumulate, greatly affecting the overall efficiency of the filter tank.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide an environmental engineering wastewater filtration tank. Utility Model Content

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] like Figure 1 As shown in the figure, an environmental engineering wastewater filter tank according to one embodiment of this utility model includes a filter tank body 1. The wastewater filter tank generally includes a filtration system and a water distribution system. The filtration system further includes a filter media layer and a support layer. When raw water enters the filter tank through the inlet pipe, it is evenly distributed on the filter media layer by the water distribution system. The filter media layer removes impurities and harmful substances in the water through physical interception and adsorption. The water filtered by the filter media layer then passes through the support layer to further remove any remaining fine particles, and finally flows out through the outlet pipe to obtain clean water.

[0022] like Figures 1-2As shown, the filter tank body 1 is equipped with several sets of separators 101, each with mesh openings. Filter media 102 is placed on the separators 101. The filter tank body 1 is also equipped with several sets of cleaning mechanisms that match the separators 101. After raw water enters the filter tank body 1 through the inlet pipe, the filter media 102 on the separators 101 intercepts impurities and harmful substances in the raw water, trapping them in the filter media 102 layer. When the amount of intercepted impurities increases, affecting the water purification efficiency of the filter tank body 1, operators can manually control the cleaning mechanisms to remove the impurities accumulated in the filter media 102 layer, thus reducing the impact of accumulated impurities on the water purification efficiency to a certain extent.

[0023] like Figure 2 As shown, the decontamination mechanism includes a partition cover 201 with a sludge outlet hole of the same size as the mesh. A stirring rod 203 is installed on the outer wall of the partition cover 201, and a first barrier cover 202 is installed at the bottom of the partition cover 201 to limit the range of sewage. The first barrier cover 202 is slidably connected to the inside of the partition mesh 101. When the operator pushes the partition cover 201 downward, the stirring rod 203 and the first barrier cover 202 move downward accordingly. When the partition cover 201 contacts the partition mesh 101, the partition cover 201 is rotated, causing the stirring rod 203 to agitate the filter medium 102, removing the impurities attached to the filter medium 102. At the same time, water is supplied to the filter tank body 1 through the water inlet pipe. Since the sludge outlet hole is larger than the pores of the filtration system, impurities can be smoothly flushed away from the sludge outlet hole in the partition cover 201 during flushing and will not continue to accumulate in the filter medium 102.

[0024] like Figure 6 As shown, several sets of short rods 2031 are installed on the outside of the stirring rod 203. By agitating the impurities and the filter medium 102 with the sets of short rods 2031, the efficiency of removing impurities from the filter medium 102 is improved to a certain extent.

[0025] like Figures 2-5 As shown, a second barrier cover 204 is slidably connected to the outer wall of the separator cover 201. The second barrier cover 204 is fixedly connected to the bottom of another set of separator mesh 101 at the top of the separator cover 201. The second barrier cover 204 has a connecting groove 2041 that matches the stirring rod 203. Under normal circumstances, the filtration speed of the upper filter medium 102 layer is faster than that of the lower filter medium 102 layer. During the filtration process, as the raw water accumulates in the bottom filter medium 102 layer, the water level may overflow the first barrier cover 202, causing the raw water to be discharged through the sewage outlet on the separator cover 201, resulting in incomplete filtration of the raw water and thus affecting the water purification effect. By blocking the sewage outlet on the separator cover 201 during the water inlet process, the situation of insufficient filtration of raw water is avoided to a certain extent.

[0026] like Figure 2As shown, a water inlet pipe 3 matching the partition cover 201 is installed on the filter tank body 1. One end of the water inlet pipe 3 is located inside the filter tank body 1, and the other end is connected to an external water source. Since the clean water entering the filter tank body 1 through the water inlet pipe needs to pass through the filtration system sequentially, it takes a certain amount of time for the clean water to reach the bottom filter medium 102 layer. This results in time for impurities in the bottom filter medium 102 layer to be flushed out, leading to a lower decontamination efficiency. By allowing water to flow through the water inlet pipe 3 to the bottom filter medium 102 layer, the impurities can be flushed away more quickly, thus improving the decontamination efficiency to some extent.

[0027] like Figure 3 As shown, the water inlet pipe 3 is located on a section of the outer wall inside the filter tank body 1, and a water outlet pipe 301 that matches the stirring rod 203 is fixedly connected to it. Each stirring rod 203 is provided with a water outlet pipe 301, which simultaneously supplies water to the multi-layer filter media 102, further improving the efficiency of flushing away impurities.

[0028] like Figure 4 As shown, an operating rod 205 for controlling the stirring rod 203 is installed on the inner wall of the first barrier cover 202, and a mounting hole 104 matching the operating rod 205 is provided on the filter tank body 1. When the operator needs to remove impurities from the filter medium 102, pressing down and rotating the operating rod 205 can achieve this, which facilitates the removal of contaminants to a certain extent.

[0029] like Figure 5 As shown, all the partition covers 201 and the first barrier cover 202 in the filter media layer of the filtration system are fixedly connected, and all the partition covers 201 and the first barrier cover 202 in the support layer are fixedly connected to each other. A push rod 206 is installed on the outer wall of the operating rod 205. A set of first barrier covers 202 in the support layer has a sliding groove 2021 that matches the push rod 206. A drive assembly that matches the push rod 206 is installed in the sliding groove 2021. Since impurities in the filter tank body 1 usually accumulate at the top and gradually decrease at the bottom, the upper part has a higher need for cleaning. When only the upper part of the filter media layer needs to be cleaned, the operator rotates the operating rod 205 180 degrees clockwise and then 180 degrees counterclockwise. At this time, the push rod 206 slides in the sliding groove 2021, which allows the upper part of the stirring rod 203 to stir in the filter medium 102 to remove impurities in the filter media layer, but does not contact the drive assembly and does not stir the filter medium in the support layer.

[0030] When the entire filter tank 1 needs to be cleaned, the operator rotates the operating lever 205 more than 360 degrees repeatedly, causing the push rod 206, in conjunction with the drive assembly, to drive the lower stirring rod 203 to agitate and clean the filter medium 102. This achieves the purpose of cleaning as needed.

[0031] like Figure 5As shown, the driving component can be two sets of symmetrically arranged blocks 207.

[0032] like Figure 1 As shown, a viewing window 105 matching the stirring rod 203 is installed on the outer wall of the filter tank body 1. Operators can observe the accumulation of impurities inside the filter tank body 1 through the viewing window 105 for decontamination.

[0033] like Figure 2 As shown, a drain port 103 matching the cleaning mechanism is installed at the bottom of the filter tank body 1. Impurities removed by the cleaning mechanism are discharged from the drain port 103, which to a certain extent prevents impurities from contaminating the outlet of clean water.

[0034] During use, the staff sends raw water into the filter tank body 1 through the inlet pipe. Impurities in the raw water remain in the filter medium 102 layer, and clean water is discharged from the drain. As the working time of the filter tank body 1 accumulates, impurities gradually accumulate in the filter medium 102, affecting the water purification efficiency. When it is necessary to remove impurities, push the operating rod 205 down until the separator 201 contacts the separator mesh 101. Then, repeatedly rotate the operating rod 205 clockwise and counterclockwise to 180 degrees. The stirring rod 203 will stir in the filter medium 102, peeling the impurities off the filter medium 102. Then, water is passed into the inlet pipe 3, and the clean water flushes the impurities out from the sewage outlet on the separator 201.

[0035] When the entire filtration system needs to be cleaned, the operating lever 205 is rotated clockwise and counterclockwise more than 180 degrees until the push rod 206 pushes the drive assembly. Then all the stirring rods 203 are stirred in the filter medium 102, and the impurities are peeled off from the filter medium 102. Then water is passed into the water inlet pipe 3, and the clean water flushes the impurities out from the dirt outlet on the partition cover 201.
