[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater separation and treatment device for sand and gravel aggregate processing. Background Technology

[0002] Sand and gravel aggregates are a general term for materials such as sand, pebbles (gravel), crushed stone, boulders, and quarries used in water conservancy projects. They are the main building materials for concrete and masonry structures in water conservancy projects. During the production process, a large amount of water is needed to wash the aggregates. After washing, the water usually contains a large amount of small-diameter sand and gravel aggregates and dust and other impurities, which cannot be directly reused by water pumps. Therefore, it is necessary to remove the impurities.

[0003] The utility model patent with announcement number CN219701173U discloses a water purification device for treating wastewater from sand and gravel aggregates, including a sedimentation tank and a sedimentation pond, which can effectively remove mud and sand from sand and gravel aggregate wastewater. However, its shortcomings are that, with the use of production time, the mud and sand at the bottom of the sedimentation tank need to be cleaned regularly. However, the structure of the sedimentation tank in this patent makes it difficult to clean the mud and sand at the bottom. In addition, the sedimentation of the wastewater entering the sedimentation tank requires a certain amount of time, and it cannot quickly separate the wastewater from sand and gravel aggregate processing. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a wastewater separation and treatment device for sand and gravel aggregate processing that can solve the above problems.

[0005] A wastewater separation and treatment device for sand and gravel aggregate processing includes a treatment unit, which comprises a receiving box, a filter box, and a water storage tank arranged sequentially from top to bottom. The receiving box has an open top and a discharge port at the bottom, located near the side of the receiving box. The filter box is inclined, with its higher end near the discharge port. The filter box has an open top, a filter screen at the bottom, and a switchable drain door at the lower end. A vibration motor is located on the outside of the filter box.

[0007] Furthermore, the second support leg includes a sleeve, a rod, and a spring. The lower end of the sleeve is movably sleeved on the upper end of the rod. The ends of the sleeve and the rod that are far apart from each other are fixedly connected to the filter box and the first support leg, respectively. The spring is sleeved on the outside of the sleeve and the rod.

[0008] Furthermore, the two ends of the drain gate are slidably connected to the sidewalls of the filter screen in the vertical direction.

[0009] Furthermore, the filter box has vertically opened sliding grooves on the outer side walls at both ends of the drain door, and sliding strips are fixed at intervals at both ends of the drain door. The drain door is slidably connected to the filter box through the sliding strips and sliding grooves.

[0010] Furthermore, a handle is provided at the top of the sewage door.

[0011] Furthermore, the bottom plates of the receiving box on both sides of the discharge port are inclined, and a fan is installed on the bottom surface of the bottom plate near the lower end of the filter box, and the fan blows air towards the filter screen.

[0012] Furthermore, the water storage tank is placed on the ground.

[0014] Furthermore, the conveying unit includes a conveying pump and a conveying pipe. The inlet and outlet of the conveying pump are respectively connected to the outlet pipe and the conveying pipe. The conveying pipe extends to the top of the receiving box of the next processing unit.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The wastewater separation and treatment device for sand and gravel aggregate processing in this utility model allows the wastewater to directly enter the filter box through the receiving box for filtration. By setting a vibration motor, the filter box vibrates, thereby quickly separating the wastewater. Due to the inclined setting of the filter box, the sand, gravel, and other impurities intercepted by the filter screen accumulate on the lower side of the filter box under the action of gravity. By setting an openable drain door on the lower side of the filter box, the impurities accumulated in the filter box can be easily removed by opening the drain door.

[0017] The wastewater separation and treatment device for sand and gravel aggregate processing in this utility model accelerates the separation between water and impurities in sand and gravel aggregate by setting up a fan and blowing air towards the filter screen.

[0018] The wastewater separation and treatment device for sand and gravel aggregate processing in this utility model, by setting at least two sets of treatment units, and the pore size of the filter screens of the treatment units decreasing in sequence, filters the wastewater for sand and gravel aggregate processing layer by layer, resulting in higher separation effectiveness.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1-4 As shown, the wastewater separation and treatment device for sand and gravel aggregate processing in this embodiment is equipped with a set of treatment units, which include a receiving box 1, a filter box 2 and a water storage box 3 arranged from top to bottom.

[0029] In this embodiment, the receiving box 1 has an opening at the top and a discharge port 11 at the bottom. The discharge port 11 has an elongated structure and is located on one side close to the receiving box 1. The bottom plates 13 on both sides of the discharge port 11 at the bottom of the receiving box 1 are inclined.

[0030] Filter box 2 is located below receiving box 1, with an opening at the top and a filter screen 21 at the bottom. Filter box 2 is tilted, with its higher end closer to the discharge port 11, allowing the wastewater from sand and gravel processing in receiving box 1 to fall onto the higher part of the filter screen 21 for easier filtration. A drain door 22 is located at the lower end of filter box 2. Impurities such as sand and gravel intercepted by the filter screen 21 accumulate at the lower end of filter box 2 under gravity. Opening the drain door 22 allows for the removal of these accumulated impurities. A vibration motor 23 is also installed on the outside of filter box 2. The vibration motor 23 causes filter box 2 to vibrate during the filtration of sand and gravel processing wastewater, accelerating the separation of the wastewater.

[0031] The water storage tank 3 is placed on the ground below the filter box 2. The upper end of the water storage tank 3 is open and the projected area of ​​the water storage tank 3 can completely cover the projected area of ​​the filter box 2, so that the filtered water falls into the water storage tank 3 for storage. The bottom of the side wall of the water storage tank 3 is connected to the water outlet pipe 4.

[0032] In this embodiment, four first mounting plates 14 are horizontally fixed on both sides of the receiving box 1 and adjacent to the drain door 22. The four first mounting plates 14 are arranged in pairs. A first support leg 12 is vertically arranged on the bottom surface of each first mounting plate 14, with its lower end supported on the ground. The first support leg 12 is located outside the filter box 2 and the water storage tank 3. A second support leg 24 is provided at the bottom of the filter box 2, and the filter box 2 is connected to the first support leg 12 via the second support leg 24. Specifically, the second support leg 24 includes a sleeve 241, a rod 242, and a spring 243. The lower end of the sleeve 241 is movably fitted onto the upper end of the rod 242. The ends of the sleeve 241 and the rod 242 that are far apart from each other are fixedly connected to the filter box 2 and the first support leg 12, respectively. The spring 243 is fitted onto the sleeve 241 and the rod 242. Preferably, a second mounting plate 28 is provided at the lower end of the insertion rod 242. The second mounting plate 28 is fixedly connected to the first support leg 12, and the two ends of the spring 243 are fixedly connected to the bottom of the filter box 2 and the second mounting plate 28, respectively.

[0033] In this embodiment, the drain door 22 can slide vertically along the sidewalls of the filter screen 21 at both ends, thereby opening or closing the drain door 22. Specifically, the filter box 2 has vertically formed grooves 25 on the outer sidewalls at both ends of the drain door 22. The upper end of the grooves 25 communicates with the outside, and the lower end is flush with the top surface of the filter screen 21. Sliding strips 26 are spaced apart at both ends of the drain door 22. The sliding strips 26 are adapted to the grooves 25. The upper end of the sliding strips 26 is fixedly connected to the top of both ends of the drain door 22 through a connecting part. The height of the drain door 22 is greater than the length of the grooves 25. The drain door 22 is slidably connected to the filter box 2 through the sliding strips 26 and the grooves 25, thereby opening and closing the drain door 22 by lifting and lowering it. Preferably, a handle 27 is provided at the top of the drain door 22.

[0034] In this embodiment, the bottom plates 13 on both sides of the discharge port 11 of the receiving box 1 are inclined. A fan 5 is installed on the bottom surface of the bottom plate 13 near the lower end of the filter box 2, and the fan 5 blows air towards the filter screen 21. Preferably, the air blowing direction of the fan 5 is vertically downward. By setting the fan 5, the separation between water and sand and gravel aggregate impurities can be accelerated.

[0035] The working principle of the wastewater separation and treatment device for sand and gravel aggregate processing in this embodiment is as follows:

[0036] The wastewater from sand and gravel aggregate processing enters the filter box 2 directly through the receiving box 1 for filtration. By setting a vibration motor 23, the filter box 2 vibrates, thereby quickly separating the wastewater from the sand and gravel aggregate processing. Due to the inclined setting of the filter box 2, the sand and gravel aggregate and other impurities intercepted by the filter screen 21 accumulate to the lower side of the filter box 2 under the action of gravity. By setting an openable drain door 22 on the lower side of the filter box 2, the impurities accumulated in the filter box 2 can be easily removed by opening the drain door 22.

[0037] Example 2:

[0038] like Figure 5 As shown, the wastewater separation and treatment device for sand and gravel aggregate processing in this embodiment is equipped with three sets of treatment units. The pore size of the filter screen 21 of the three sets of treatment units decreases sequentially, and a conveying unit is set between adjacent treatment units. Specifically, the conveying unit includes a conveying pump 6 and a conveying pipe 7. The inlet end of the conveying pump 6 is connected to the outlet pipe 4 of the previous treatment unit, and the outlet end of the conveying pump 6 is connected to the conveying pipe 7. The conveying pump 6 is installed on the ground, and the end of the conveying pipe 7 away from the conveying pump 6 extends to the top of the receiving box 1 of the next treatment unit. The conveying pipe 7 can be fixed by a bracket or other structure.

[0039] By setting up three sets of processing units, with the pore size of the filter screen 21 of the processing units decreasing sequentially, the wastewater from sand and gravel aggregate processing can be filtered layer by layer, resulting in higher separation effectiveness.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
