Description

Technical Field

[0001] The utility model relates to the technical field of sewage purification, in particular to a sewage purification device for a construction site. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.

[0003] During construction, construction wastewater is generated. Construction wastewater test papers detect various wastewaters generated on construction sites, including washing water generated when cleaning concrete equipment, tools and vehicles, wastewater generated during concrete mixing, etc. Usually, construction wastewater is mixed with some fine particles. Therefore, when wastewater needs to be recycled, the particles and floating objects in the wastewater need to be treated first to further purify the construction wastewater.

[0004] For example, in the Chinese utility model patent with the announcement number CN 221051594 U, a laboratory sewage purification device is disclosed, and its technical solution is as follows: it includes a treatment tank and support legs, and the four support legs are respectively fixedly connected to the four corners of the lower surface of the treatment tank. The top of the treatment tank is provided with a filtering device, and the interior of the treatment tank is provided with a purification device. The filtering device includes a filtering unit, a cleaning unit and a sewage discharge unit. The filtering unit includes a filter box, a water inlet pipe, and a filter screen. The filter box is fixedly connected to the left side of the top of the treatment tank, the water inlet pipe is fixedly connected to the top center of the filter box, and the filter screen is installed at the bottom of the filter box. The sewage enters the interior of the filter box through the water inlet pipe, and then passes through the filter screen to intercept and filter the large particles of impurities in the sewage.

[0005] The applicant has found that, although the above technical solution can intercept and filter large particles of impurities in sewage, there are still some problems that need to be improved. For example, when the impurities on the filter net are pushed out by the push plate, because the impurities pass through the filter net, when the impurities pass through the filter net, they will inevitably pass through the holes opened in the filter net, causing the impurities to be stuck in the holes on the filter net, resulting in clogging of the filter net. In view of this, we propose a sewage purification device for construction sites to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a sewage purification device for a construction site to solve the problems existing in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction site sewage purification device, comprising a mixing box, the top surface of the mixing box is connected to a filter box, the top surface of the filter box is connected to a water inlet pipe, the top surface of the mixing box is connected to a medicine supplement pipe, a cylinder is fixed to the right end of the filter box, the left end of the filter box is connected to a mud outlet pipe, the other end of the mud outlet pipe is also connected to a collection box fixed to the left end of the mixing box, a push plate is fixed to the output end of the cylinder, a filter assembly is arranged in the filter box, and a disassembly assembly is arranged on the front of the filter box;

[0008] The filter assembly includes a mounting frame arranged in the filter box, a filter net is installed on the top surface inside the mounting frame, an adsorption net is installed on the bottom surface inside the mounting frame, sealing strips are installed on the top and bottom surfaces of the mounting frame, and positioning blocks are fixed on both left and right ends of the mounting frame.

[0009] Furthermore, a square hole is opened on the front side of the filter box, and the mounting frame is located inside the square hole and is slidably connected thereto.

[0010] Furthermore, the left and right ends of the square hole are connected with positioning holes, and the two positioning blocks are respectively located inside the two positioning holes and are slidably connected thereto.

[0011] Furthermore, the disassembly assembly includes a bracket fixed on the front side of the filter box, the bracket is internally slidably connected to a limit rod, a retaining ring is fixed to the outer surface of the limit rod, a spring is fixed to the top surface of the retaining ring, a connecting frame is fixed to the front side of the mounting frame, and a pull ring is fixed to the top surface of the limit rod.

[0012] Furthermore, a limiting hole is provided inside the connecting frame, and the bottom end of the limiting rod is located in the limiting hole and is slidably connected thereto.

[0013] Furthermore, the spring is sleeved with the limiting rod, and the top end of the spring is fixed with the bottom end of the bracket.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The sewage purification device at the construction site can conveniently block the fine particles mixed in the sewage entering the mixing box by setting a filtering component, thereby preventing the fine particles from entering the mixing box and thus hindering the sewage purification work. In addition, some fine impurities in the sewage can be adsorbed through the adsorption net, thereby achieving the purpose of improving the sewage purification efficiency. At the same time, it also avoids the inclusion of particles in the sewage, resulting in residual particles in the purified water, which affects the subsequent use of the purified water.

[0016] 2. In the sewage purification device for construction sites, when the construction sewage enters the mixing tank for purification, the sewage will first pass through the filter net and the adsorption net to block the larger particles in the sewage and adsorb the fine impurities. When too many particles or impurities are blocked or adsorbed, the filter net and the adsorption net will be clogged. By setting up a disassembly component, the installation frame can be quickly disassembled, so that the filter net and the adsorption net installed in the installation frame can be cleaned or replaced, thereby improving the efficiency of replacing the filter net and the adsorption net.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 and Figure 2 A construction site sewage purification device in this embodiment includes a mixing box 1, the top surface of the mixing box 1 is connected to a filter box 2, the front of the filter box 2 is provided with a square hole, the top surface of the filter box 2 is connected to a water inlet pipe 3, the top surface of the mixing box 1 is connected to a tonic pipe 4, a cylinder 5 is fixed to the right end of the filter box 2, the left end of the filter box 2 is connected to a mud outlet pipe 6, the other end of the mud outlet pipe 6 is also connected to a collecting box 7 fixed at the left end of the mixing box 1, a push plate 8 is fixed to the output end of the cylinder 5, a filter assembly is provided in the filter box 2, and a disassembly assembly is provided on the front of the filter box 2.

[0024] By setting up the filtering component, the sewage entering the mixing box 1 can be effectively pre-filtered, thereby filtering the sand and gravel in the sewage, and at the same time, the fine particles in the sewage can be adsorbed, avoiding the problem of unqualified purification due to excessive sand and gravel and fine impurities in the sewage during the sewage purification process.

[0025] See also Figure 2 and Figure 3 In order to filter the fine particles mixed in the water entering the mixing box 1, the filter assembly in this embodiment includes a mounting frame 10 arranged in the filter box 2, the mounting frame 10 is located inside the square hole and is slidably connected thereto, a filter net 9 is installed on the top surface inside the mounting frame 10, an adsorption net 11 is installed on the bottom surface inside the mounting frame 10, sealing strips 12 are installed on the top and bottom surfaces of the mounting frame 10, positioning blocks 13 are fixed on the left and right ends of the mounting frame 10, and the left and right ends of the square hole are also connected to positioning holes, and the two positioning blocks 13 are respectively located inside the two positioning holes and are slidably connected thereto.

[0026] When the sewage enters the mixing box 1 through the water inlet pipe 3, the sewage will first enter the filter box 2, and the sewage will continue to move downward under the action of gravity. When the sewage passes through the filter net 9, the larger sand and gravel mixed in the sewage will be filtered, and the filtered water will continue to fall downward. During the falling process, it will pass through the adsorption net 11, and the adsorption net 11 will adsorb the fine particles in the sewage, thereby avoiding the mixing of sand and gravel and fine particles in the sewage, and further enter the mixing box 1 through the water inlet hole opened on the top surface of the mixing box 1, thereby realizing the preliminary filtration of the sewage.

[0028] When the filter screen 9 or the adsorption screen 11 is blocked, first pull the pull ring 19 upwards. When the pull ring 19 moves upwards, it will drive the limit rod 15 to move upwards. In the process of the limit rod 15 moving upwards, it will drive the retaining ring 16 on the outer surface of the limit rod 15 to move upwards.
