Description

Technical Field

[0001] This utility model relates to the technical field of wastewater recycling systems, specifically, to a wastewater recycling system. Background Technology

[0002] A concrete batching plant is a combined facility used for centralized mixing of concrete, also known as a precast concrete plant. The main working principle of a concrete batching plant is to use cement as a binder to mix raw materials such as sand, gravel, lime, and cinders, ultimately producing concrete. Concrete batching plants generate a large amount of wastewater during operation, which often contains sand, gravel, and other materials. Direct discharge of this wastewater would lead to environmental pollution and resource waste.

[0003] An existing wastewater recovery and recycling system for concrete mixing plants includes a wastewater tank, filter barrels, a water pump, a hose, and a repositioning drive mechanism. Multiple filter barrels are placed inside the wastewater tank. The upper end of each filter barrel is open, and the side walls and / or bottom walls of the filter barrels have filter holes with a diameter smaller than the particle size of sand and gravel. The water pump is used to pump wastewater generated by the concrete mixing plant. One end of the hose is connected to the outlet of the water pump, and the other end of the hose is located above the wastewater tank. The repositioning drive mechanism drives the end of the hose away from the water pump to face the opening of any filter barrel.

[0004] The aforementioned technology utilizes filter cartridges to remove sand and gravel from wastewater, allowing for wastewater recycling and reuse, thereby reducing environmental pollution and resource waste. However, in practical use, wastewater may contain a large amount of sand and gravel, which can gradually accumulate on the surface of the filter cartridge over time, causing blockages. This can lead to a large amount of wastewater accumulating inside the filter cartridge, increasing its internal weight. Consequently, when workers remove and clean the filter cartridge, they must first clear the wastewater from the inside, making the process more cumbersome and increasing the workload for the workers. Utility Model Content

[0005] This invention proposes a wastewater recycling system, which solves the problem that workers need to clean the wastewater inside the filter can before taking it out, making the operation cumbersome and reducing the labor intensity of the workers.

[0006] The technical solution of this utility model is as follows: A wastewater recycling system includes a wastewater tank. At least two support plates are provided on one side of the wastewater tank near the top. Each support plate is provided with a support frame, and each support frame is provided with a filter bucket. Each filter bucket has an opening at the top. The two support frames are connected by a connecting plate. A vibration motor is fixedly connected to the connecting plate. A water pump is provided on one side of the wastewater tank. The output end of the water pump is connected to one end of an inlet hose, and the other end of the inlet hose faces the opening of any filter bucket.

[0007] Furthermore, each of the support plates is provided with a shock-absorbing mechanism at its top. The shock-absorbing mechanism includes a shock-absorbing plate and a plurality of first elastic elements. One end of each first elastic element is fixedly connected to the top of the support plate, and the other end of each first elastic element is fixedly connected to the shock-absorbing plate. The support frame is disposed on top of the shock-absorbing plate and fixedly connected to the shock-absorbing plate.

[0008] Furthermore, the support frame is provided with an annular positioning groove at the top, and the outer surface of the filter barrel is provided with an annular positioning block. The annular positioning block is slidably connected to the inner wall of the annular positioning groove, and the support frame is provided with a fixing component to prevent the filter barrel from dislodging from the annular positioning groove.

[0009] Furthermore, the fixing assembly includes a fixing plate, a fixing block, a second elastic element, and a pull rod. An extension plate is provided on one side of the support frame. One side of the fixing plate is rotatably connected to the support frame. A retaining plate is provided on the other side of the fixing plate. A receiving block is fixedly connected to the top of the extension plate. A receiving groove is provided inside the receiving block. The fixing block is slidably connected to the inner wall of the receiving groove, and one end extends to the outside of the receiving block. One end of the second elastic element is fixedly connected to the fixing block, and the other end of the second elastic element is fixedly connected to the side of the receiving groove. The retaining plate and its top abut against the bottom of the fixing block. The pull rod is located on the side of the fixing block facing the second elastic element and extends to the outside of the receiving block.

[0010] Furthermore, guide grooves are provided on both sides of the receiving groove, and guide blocks are provided on both sides of the fixing block, with the guide blocks slidingly connected to the inner wall of the guide groove.

[0011] Furthermore, the bottom of the card plate has an arc-shaped structure, and the top of the fixing block is provided with a first inclined surface that is slidably connected to the card plate.

[0012] Furthermore, each wastewater tank is provided with a placement block on the side near the opening of each filter bucket. The placement block is provided with a placement groove for placing the inlet hose and a fixing sleeve for fixing the inlet hose. One side of the fixing sleeve is rotatably connected to one side of the placement block, and the other end of the fixing sleeve is fixedly connected to the other side of the placement block by bolts.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] When workers start the water pump and discharge wastewater into the filter canister through the inlet hose, the filter canister filters out the sand and gravel in the wastewater. The sand and gravel are blocked and retained inside the filter canister, while the wastewater is discharged through the filter holes on the canister, achieving separation of sand and gravel from wastewater. Simultaneously, workers can start the vibrating motor. The vibration energy generated by the motor is transmitted to the support frame through the connecting plate, causing the filter canister to vibrate. This reduces the risk of filter canister clogging, allowing wastewater inside the canister to drain through the filter holes, thus reducing the weight of the filter canister and ensuring complete wastewater discharge. When removing the filter canister and cleaning the filter cylinder, workers no longer need to pre-clean the wastewater inside, making the operation simpler and reducing labor intensity.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] refer to Figure 1-9 A wastewater recycling system includes a wastewater tank 1. At least two support plates 101 are provided on one side of the wastewater tank 1 near the top. The support plates 101 can be fixedly connected to the inner wall of the wastewater tank 1 by bolts 503. In addition, reinforcing ribs can be provided between the support plates 101 and the inner wall of the wastewater tank 1 to improve the support strength of the support plates 101. Each support plate 101 is provided with a support frame 102, and each support frame 102 is provided with a filter barrel 103. Each filter barrel 103 has an opening 104 at the top. The two support frames 102 are connected by a connecting plate 105. A vibration motor 106 is fixedly connected to the connecting plate 105. A water pump 108 is provided on one side of the wastewater tank 1. The output end of the water pump 108 is connected to one end of an inlet hose 109. The other end of the inlet hose 109 faces the opening 104 of any filter barrel 103.

[0028] Secondly, by setting up two filter tanks 103, the water pump 108 can be kept running continuously to separate sand and gravel from the wastewater. When the sand and gravel inside one filter tank 103 accumulates to a certain level, the operator can redirect the inlet hose 109 to the opening 104 of the other filter tank 103 (note that the inlet hose 109 should have some length reserved so that the inlet hose can be switched back and forth between the openings 104 of the two filter tanks 103), allowing the wastewater to enter the other filter tank 103. Then, the filter tank 103 filled with sand and gravel can be removed, and the sand and gravel inside can be reused to reduce resource waste. The filtered wastewater can be stored in wastewater pool 1 and used as clean water for subsequent cleaning of cement trucks and other equipment in the mixing plant (note that the level of wastewater stored in wastewater pool 1 must not exceed the level of the filter tank 103).

[0029] Furthermore, in order to reduce the vibration generated by the vibration motor 106 transmitted to the wastewater tank 1, a shock-absorbing mechanism is provided on the top of each support plate 101. The shock-absorbing mechanism includes a shock-absorbing plate 201 and several first elastic elements 2 (the first elastic elements 2 can be cylindrical compression springs, and the several first elastic elements 2 have sufficient elastic coefficients to support the weight of the vibration motor 106 and each filter tank 103). One end of each first elastic element 2 is fixedly connected to the top of the support plate 101, and the other end of each first elastic element 2 is fixedly connected to the shock-absorbing plate 201. The support frame 102 is set on the top of the shock-absorbing plate 201 and fixedly connected to the shock-absorbing plate 201. There is a gap between the bottom of the filter tank 103 and the top of the shock-absorbing plate 201, so that sewage can be discharged through the bottom of the filter tank 103.

[0030] When the vibratory motor 106 starts, the vibration energy it generates is transmitted to the support frame 102 through the connecting plate 105, and the support frame 102 transmits the vibration to the damping plate 201. Since the bottom of the damping plate 201 is provided with several first elastic elements 2, these elastic elements absorb the vibration energy and reduce the transmission of vibration, thereby reducing the vibration frequency of the wastewater pool 1 and avoiding interference of vibration to surrounding equipment.

[0031] In this embodiment, the support frame 102 is provided with an annular positioning groove 202 at the top, and the filter bucket 103 is provided with an annular positioning block 203 on the outer surface. The annular positioning block 203 is slidably connected to the inner wall of the annular positioning groove 202. The support frame 102 is provided with a fixing component to prevent the filter bucket 103 from disengaging from the annular positioning groove 202 at the top.

[0032] By setting the annular positioning groove 202 and the annular positioning block 203, the filter canister 103 can be positioned conveniently and quickly, thus simplifying the installation process for operators. The setting of the fixing components can prevent the filter canister 103 from being dislodged from the annular positioning groove 202 due to vibration, ensuring that the filter canister 103 is firmly held in the annular positioning groove 202, thereby ensuring the continuity and stability of the filtration process.

[0033] Specifically, the fixing components include a fixing plate 3, a fixing block 301, a second elastic element 302 (the second elastic element 302 can be a cylindrical compression spring), and a pull rod 303. An extension plate 304 is provided on one side of the support frame 102. One side of the fixing plate 3 is rotatably connected to the support frame 102. A clamping plate 305 is provided on the other side of the fixing plate 3. A receiving block 306 is fixedly connected to the top of the extension plate 304. A receiving groove 307 is provided in the receiving block 306. The fixing block 301 is slidably connected to the inner wall of the receiving groove 307 and one end extends to the outside of the receiving block 306. One end of the second elastic element 302 is fixedly connected to the fixing block 301, and the other end of the second elastic element 302 is fixedly connected to the side of the receiving groove 307. The clamping plate 305 abuts against the top and bottom of the fixing block 301. The pull rod 303 is located on the side of the fixing block 301 facing the second elastic element 302 and extends to the outside of the receiving block 306.

[0034] When the operator needs to fix the filter canister 103, first pull the lever 303 with one hand. At this time, the fixing block 301 will retract into the receiving groove 307 and compress the second elastic element 302. Then, with the other hand, rotate one side of the fixing plate 3 around the support frame 102 so that the bottom of the clamping plate 305 contacts the top of the extension plate 304. Finally, release the lever 303. Under the action of the second elastic element 302, the fixing block 301 will automatically extend and contact the top of the clamping plate 305, thereby fixing the clamping plate 305 in the appropriate position and preventing it from rotating. To facilitate the fixing of the filter canister 103, the bottom of the clamping plate 305 is designed with an arc shape, and the top of the fixing block 301 is provided with a first inclined surface 310 that slides with the clamping plate 305. With the first inclined surface 310, the operator does not need to pull the lever 303 before fixing the filter canister 103. Simply align the arc-shaped end of the clamping plate 305 with the first inclined surface 310 and apply force to overcome the reaction force of the second elastic element 302. Under the action of the clamping plate 305 and the first inclined surface 310, the fixing block 301 will gradually compress the second elastic element 302, causing it to retract into the receiving groove 307. When the bottom of the clamping plate 305 contacts the top of the extension plate 304, the fixing block 301 will automatically extend under the action of the second elastic element 302, thereby achieving fixation and improving the work efficiency of the operator in fixing the filter barrel 103.

[0035] When it is necessary to remove the filter canister 103, the operator can remove it either by stopping the vibration motor 106 or while the vibration motor 106 is operating. Removing the filter canister 103 while the vibration motor 106 is operating may be difficult. Therefore, the best practice is to remove the filter canister 103 after the vibration motor 106 has stopped operating. First, the operator needs to pull the handle to retract the fixing block 301 into the receiving groove 307. Then, using the other hand, the operator rotates the fixing plate 3 around one side of the support frame 102 to disengage the bottom of the fixing plate 3 from the top of the filter canister 103. Finally, the filter canister 103 can be removed.

[0036] Furthermore, compared with the traditional bolt 503 connection method, the fixing component in this embodiment is less likely to be gradually loosened by the vibration motor 106, preventing it from falling out of the annular positioning groove 202, thereby improving the stability of the filter barrel 103 inside the annular positioning groove 202.

[0037] In this embodiment, to prevent the fixing block 301 from shifting or misaligning during movement, guide grooves 309 are provided on both sides of the receiving groove 307, and guide blocks 308 are provided on both sides of the fixing block 301. The guide blocks 308 are slidably connected to the inner wall of the guide grooves 309. By setting the guide blocks and guide grooves 309, the fixing block 301 can only move along the inner wall of the guide grooves 309, thereby improving the stability of the fixing block 301 during movement and preventing shifting or misalignment during movement. At the same time, this arrangement can ensure that the second elastic element 302 is subjected to uniform force, thereby improving its service life.

[0038] In this embodiment, in order to facilitate the workers to fix the water inlet hose 109, a placement block 5 is provided on the side of the wastewater tank 1 near the opening 104 of each filter bucket 103. The placement block 5 is provided with a placement groove 501 for placing the water inlet hose 109. The placement block 5 is provided with a fixing sleeve 502 for fixing the water inlet hose 109. One side of the fixing sleeve 502 is rotatably connected to one side of the placement block 5, and the other end of the fixing sleeve 502 is fixedly connected to the other side of the placement block 5 by a bolt 503.

[0039] By using the placement block 5, when it is necessary to fix the water inlet hose 109, first rotate the fixing sleeve 502 around one side of the placement block 5. Then, place the water inlet hose 109 inside the placement groove 501. Next, rotate the fixing sleeve 502 to cover the surface of the water inlet hose 109, and finally fix the fixing sleeve 502 to fix the water inlet hose 109 in place. When switching is required, loosen the bolt 503, then rotate the fixing sleeve 502 around the placement block 5, and finally remove the water inlet hose 109.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
