Description

Technical Field

[0001] The present application relates to the technical field of concrete production, and in particular to a wastewater treatment device for concrete production. Background Art

[0002] A large amount of sewage is often produced during the concrete production process. This sewage not only contains conventional building materials such as sand, gravel and cement, but also contains various types of concrete additives. If it is discharged directly, it will cause serious pollution to the natural environment and greatly waste a large amount of sand, gravel and other building materials in the sewage.

[0003] For example, a Chinese patent (publication number: CN219744067U) discloses a wastewater treatment device for ready-mixed concrete production. After the first filter plate has been used for a long time, the sealing plate is opened, and then the first filter plate is taken out from the taking port, and the first filter plate can be replaced, thereby improving the problem of affecting the wastewater treatment efficiency; when the first filter plate is placed in the device body, the pop-up spring is compressed. When the sealing plate is opened, the pop-up spring can provide thrust to the pop-up plate, and the pop-up plate applies a force to the first filter plate, so that the first filter plate pops out from the taking port, making it convenient for the staff to take the first filter plate.

[0004] The above-mentioned device is provided with a detachable filter plate to facilitate cleaning of the filter plate after long-term use, so as to avoid clogging of the mesh of the filter plate and affect the treatment efficiency. However, since concrete wastewater treatment is usually centralized, the amount to be treated is large, so the volume of the concrete wastewater treatment device is also large, which means that the volume and weight of the filter plate in the above-mentioned device are very large. Therefore, even if the above-mentioned filter plate can be disassembled and assembled, the disassembly and assembly process requires a lot of manpower and material resources. If the volume of the filter plate is too small, the wastewater treatment efficiency is too low. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] See also Figure 1-2 In this embodiment, a wastewater treatment device for concrete production includes a wastewater treatment pool 1, a coarse sand filter 2 is fixed to the inner top wall of the wastewater treatment pool 1, an auxiliary mechanism 3 for improving the filtering effect is provided on the wastewater treatment pool 1, a wastewater collection mechanism 4 is provided on the wastewater treatment pool 1, and a fence 5 is fixed around the top surface of the wastewater treatment pool 1.

[0032] See also Figure 1 and Figure 3 In order to improve the practicability of the device and save manpower and material resources, the auxiliary mechanism 3 includes a power component arranged on the coarse sand filter screen 2, a driving component arranged on the power component, and the auxiliary mechanism 3 also includes a filtering component arranged inside the wastewater treatment tank 1.

[0033] Among them, the power component includes a power motor 301 fixedly installed on the front and back of the top of the coarse sand filter 2, a stirring shaft 302 fixed on the output shaft of the power motor 301 and rotatably connected to the bottom wall of the wastewater treatment tank 1, and an active bevel gear 303 fixed in the middle position of the outer surface of the stirring shaft 302. The power motor 301 can drive the stirring shaft 302 to rotate. During the rotation process, the stirring shaft 302 can quickly mix and react the wastewater after secondary filtration with the wastewater treatment agent.

[0034] At the same time, the driving component includes two rotating shafts 304 distributed front and back on the left and right sides of the inner wall of the wastewater treatment tank 1 through bearings, driven bevel gears 305 fixed at opposite ends of the four rotating shafts 304 and respectively meshed with the left and right sides of the two active bevel gears 303, a connecting rod 306 fixed on the outer surface of the rotating shaft 304 away from the driven bevel gear 305, and a cam 307 fixed at the bottom end of the connecting rod 306. During the rotation of the active bevel gear 303, the rotating shaft 304 can be driven to rotate through the driven bevel gears 305 on the left and right sides, thereby further driving the cam 307 to rotate.

[0035] In addition, the length of the right connecting rod 306 is greater than that of the left connecting rod 306, and a clearance hole is opened at the top of the left side of the wastewater treatment tank 1 to facilitate the silt roller to the waste collection tank 313 for unified collection.

[0036] In addition, the filter assembly includes a fixing frame 308 fixed on the left and right sides of the inner wall of the wastewater treatment tank 1, two support rods 309 fixed between the inner top wall and the inner bottom wall of the fixing frame 308 and distributed front to back, a fine filter screen 310 slidably connected to the outer surface of the four support rods 309, an auxiliary spring 311 movably mounted on the top of the outer surface of the support rod 309, and a fixing plate 312 fixed on the left and right sides of the bottom surface of the fine filter screen 310 and distributed front to back. The filter assembly also includes a waste collection tank 313 arranged on the left side of the wastewater treatment tank 1. The driving assembly can make the fine filter screen 310 vibrate continuously with the cooperation of the auxiliary spring 311, so that the sand and gravel on the top of the fine filter screen 310 can roll to the lower left.

[0037] It should be noted that the four fixed plates 312 are respectively located directly above the four cams 307, the fixed plates 312 are arc-shaped, and the fine filter screen 310 is inclined with the left side lower and the right side higher. When the cam 307 rotates to the side close to the fixed plate 312, it can push the fixed plate 312 to move upward. If the cam 307 continues to rotate, it will no longer have a supporting effect on the fixed plate 312.

[0038] See also Figure 1-2 In order to facilitate the centralized storage of treated wastewater, the wastewater collection mechanism 4 includes a water pump 401 fixedly installed on the front right side of the top of the wastewater treatment tank 1, and a pumping pipe 402 fixed at the input end of the water pump 401 and extending to the bottom of the wastewater treatment tank 1. The wastewater collection mechanism 4 also includes a wastewater collection tank 403 arranged on the right side of the wastewater treatment tank 1, and a water supply pipe 404 fixed at the output end of the water pump 401 and extending to the inside of the wastewater collection tank 403.

[0039] Finally, a fixing hole is opened on the front right side of the top of the fine filter mesh 310, and the water suction pipe 402 passes through the fixing hole and extends to the bottom of the fine filter mesh 310. The water suction pipe 402 is a hard pipe to prevent the fine filter mesh 310 from rubbing against the water suction pipe 402 during vibration.

[0040] The working principle of the above embodiment is:

[0041] When the device is used to treat wastewater from concrete production, the treatment agent required for treating the wastewater is first poured into the bottom of the wastewater treatment tank 1, and then the wastewater is poured into the wastewater treatment tank 1 from the top of the coarse sand filter 2. The coarse sand filter 2 can initially filter out the larger sand and gravel particles in the wastewater, and then the wastewater flows downward to the top of the fine filter 310. The fine filter 310 can further filter the wastewater and flow to the bottom of the fine filter 310. The filtered sediment is retained on the top of the fine filter 310. At the same time, the power motor 301 drives the stirring shaft 302 to rotate. The stirring shaft 302 drives the active bevel gear 303 to rotate during the rotation, and drives the rotating shaft 304 to rotate with the cooperation of the driven bevel gear 305. The rotating shaft 304 drives the cam 304 during the rotation. 7 rotates, and when the cam 307 rotates upward and approaches the fixed plate 312, the fine filter screen 310 can be pushed to move upward. When the cam 307 continues to rotate and no longer has a supporting effect on the fixed plate 312, the fine filter screen 310 moves downward under the action of the elastic potential energy of the auxiliary spring 311. Therefore, the cam 307 can make the fine filter screen 310 vibrate up and down during the continuous rotation, and at the same time, the mud and sand on the top of the fine filter screen 310 rolls to the lower left into the waste collection tank 313. In addition, the stirring shaft 302 can make the wastewater that has undergone secondary filtration and the wastewater treatment agent quickly mix and react during the rotation process. Finally, the treated wastewater is pumped out of the wastewater treatment tank 1 through the pumping pipe 402 by the water pump 401, and is transported to the wastewater collection tank 403 by the water delivery pipe 404 for storage, so as to facilitate subsequent treatment.
