Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a high-efficiency filtering device for water sources at a construction site, belonging to the technical field of construction sites. Background Art

[0002] A construction site, also known as a building site, construction site, or simply a site, is a place where a construction project is being developed and civil engineering is being carried out. It is often enclosed by fences, wire mesh, or walls to restrict the entry and exit of personnel, materials, machinery, and vehicles. Before construction workers enter the construction site, they must receive education and assessment on construction safety and fire protection knowledge;

[0003] A Chinese public patent (publication number: CN 107098490 B) discloses a construction site sewage treatment equipment. The technical problem to be solved by the present invention is to provide a construction site sewage efficient treatment equipment that can treat debris in sewage without damaging the machine, has good purification effect and fast speed. In order to solve the above technical problems, the present invention provides such a construction site sewage efficient treatment equipment, including a support leg, a first box body, a first water outlet pipe, a first cross plate, a sewage treatment device, etc.; the first box body is installed on the top of the support leg by bolt connection, and the first water outlet pipe is connected to the middle of the bottom of the first box body, and the first water outlet pipe is connected to the first box body. The present invention uses the first cross plate to filter large debris in the sewage, and then the first rolling roller and the second rolling roller rotate in opposite directions to roll the smaller debris in the first box body.

[0004] As described in the above case, there may be a lot of debris in the water source, so it needs to be crushed, but the crushed debris will fall vertically to the top of the sewage treatment mechanism due to gravity. When the crushed debris accumulates too much and completely covers the sewage treatment mechanism, it may cause the flow rate of the water source entering the sewage treatment mechanism to decrease, thereby reducing its filtration efficiency and affecting the normal filtration of the water source. At the same time, the scraper set at the bottom can clean the silt at the water inlet position, but the cleaned silt will also fall on the top of the treatment device, thereby affecting the normal filtration of the water source. For this reason, a high-efficiency filtration device for water sources in construction sites is proposed. Utility Model Content

[0005] In view of this, the utility model provides a high-efficiency filtering device for water source at a construction site to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides a high-efficiency filtering device for water sources at construction sites, including a filter box 1, the top of the filter box 1 is connected to a water inlet pipe 4, the bottom of the filter box 1 is connected to a water outlet pipe 5, a filter screen 11 is fixedly installed on the left side of the bottom of the inner cavity of the filter box 1, a feed trough 9 is opened on the top of the right side of the inner cavity of the filter box 1, a screen screen 8 is arranged in the inner cavity of the filter box 1, a crushing mechanism 2 is arranged on the right side of the filter box 1, the crushing mechanism 2 includes a crushing box 201, and a dredging mechanism 3 is arranged on the left side of the filter box 1, and the dredging mechanism 3 includes a second motor 301.

[0027] By setting up the crushing mechanism 2, the crushed foreign matter can be collected to prevent it from falling on the top of the filtering device and affecting the normal filtering of the water source. By setting up the dredging mechanism 3, the sludge can be scraped off to prevent the sludge from accumulating at the bottom of the equipment and affecting the normal filtering of the water source. At the same time, the sludge passes through the filtering device into the drainage pipe. The drainage pipe is often not completely vertical, which will cause the sludge to accumulate at the bend of the pipe, and then cause the problem that the water source cannot be discharged normally.

[0028] Example 2

[0029] In one embodiment, a crushing box 201 is fixedly installed on the right side of the filter box 1, a mounting plate 202 is fixedly installed on the rear side of the crushing box 201, a first motor 203 is fixedly installed on the rear side of the mounting plate 202, a driving gear 204 is fixedly connected to the output end of the first motor 203, a driven gear 205 is movably connected to the left side of the rear side of the crushing box 201, the driving gear 204 and the driven gear 205 are meshed with each other, a crushing shaft 206 is fixedly installed on the rear sides of the driving gear 204 and the driven gear 205, a collecting box 207 is placed at the bottom of the inner cavity of the crushing box 201, slots 10 are opened on the left and right sides of the inner cavity of the filter box 1, a screen 8 is inserted into the inner cavity of the slot 10, a flange 6 is fixedly installed on the top of the water inlet pipe 4 and the bottom of the water outlet pipe 5, and a screw groove 7 is opened on the top of the flange 6.

[0030] By setting up the collecting box 207, the crushed foreign matter can be conveniently collected, and the operator can be convenient to clean the foreign matter. By setting up the slot 10, the screen 8 can be conveniently disassembled and replaced, avoiding the sieve hole size on the surface becoming larger after long-term use, and then failing to guide and filter the foreign matter in the water source. By setting up the flange 6, the length of the water inlet pipe 4 and the water outlet pipe 5 can be conveniently extended, thereby improving the overall effect of the equipment in filtering water sources at different locations.

[0031] Example 3

[0032] In one embodiment, the second motor 301 is fixedly installed on the left side of the filter box 1, and the output end of the second motor 301 is fixedly connected to a screw rod 302, the outer surface of the screw rod 302 is connected to a threaded block 303 by a thread, and a vertical rod 304 is fixedly installed at the bottom of the threaded block 303, and a scraper 305 is fixedly connected to the bottom of the vertical rod 304. A material drop chute 306 is opened on the right side of the bottom of the inner cavity of the filter box 1, and a sludge box 307 is fixedly installed on the right side of the bottom of the filter box 1 by screws, and a rubber ring 308 is fixedly installed on the left side of the bottom of the filter box 1, and the inner side of the rubber ring 308 is in contact with the outer side of the sludge box 307. A limiting groove 309 is opened on the rear side of the inner cavity of the filter box 1, and a limiting rod 310 is fixedly installed on the rear side of the threaded block 303, and the rear side of the limiting rod 310 is movably connected to the inner cavity of the limiting groove 309.

[0033] By setting up the sludge box 307, the sludge can be collected, which is convenient for the operator to clean the collected sludge, thereby improving the overall working efficiency of the equipment. By setting up the rubber ring 308, the problem of water leakage at the connection between the sludge box 307 and the filter box 1 can be avoided, and the environment around the equipment can be avoided from being polluted by water leakage. By setting up the limit rod 310 and the limit groove 309, the movement of the threaded block 303 can be limited to avoid it rotating synchronously with the screw rod 302 when moving, resulting in the inability to scrape off the sludge normally.

[0034] When the utility model is working, after the water source enters the inner cavity of the filter box 1 through the water inlet pipe 4, since the screen 8 is in an inclined state, the foreign matter in the water will enter the inner cavity of the crushing box 201 through the feed trough 9 at its inclined angle, and then the output end of the first motor 203 drives the driving gear 204 to rotate, and the driven gear 205 meshing with it rotates synchronously, and the crushing shaft 206 crushes the foreign matter, and the crushed foreign matter will fall into the inner cavity of the collection box 207 and enter the filter box 1 at the same time. The water source in the cavity contains a certain amount of silt, which will fall to the bottom of the inner cavity of the filter box 1 under the influence of gravity. At this time, the output end of the second motor 301 drives the screw 302 to rotate, and makes the threaded block 303, the vertical rod 304 and the scraper 305 move to the right synchronously. The scraper 305 can scrape the silt at the bottom of the inner cavity of the filter box 1 through the inner cavity of the drop chute 306 into the silt box 307 to complete the dredging work. Then the water source enters the outlet pipe 5 through the filtration of the filter screen 11 and is discharged.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
