Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete slurry recycling devices, specifically, to a concrete slurry recycling and mixing equipment. Background Technology
[0002] Concrete slurry refers to the water that seeps onto the surface of concrete due to the settling of solid particles and the rising of water in the concrete mix. It also includes wastewater from washing concrete batching plants. Concrete slurry can be recycled and reused. The main purpose of concrete slurry recycling is to conserve water resources, reduce environmental pollution, and generate economic benefits. Through a recycling system, this wastewater can be reused, reducing the amount of fresh water used. Concrete slurry contains alkaline substances such as cement and sand; if directly discharged into the environment, it will pollute the surrounding soil and water. Recycling and reuse effectively solves this problem and avoids environmental pollution. The recycling system not only reduces the amount of fresh water used but also allows the treated slurry to be used in production, reducing production costs.
[0003] The slurry contains large aggregate particles and small silt particles. Existing slurry recycling devices mostly use primary screening to separate large aggregate particles, resulting in relatively turbid recycled wastewater. At the same time, small silt particles mixed in the wastewater directly enter the pump, causing significant damage to the pump and reducing its service life. In addition, small silt particles tend to accumulate inside the slurry recycling device and solidify on the inner wall, making them difficult to clean. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a concrete slurry recycling and preparation equipment, which solves the technical problems of existing slurry recycling devices not being able to filter small particles of mud and sand, resulting in significant damage to the pump when the pump is pumping waste liquid, and the small particles of mud and sand being difficult to clean and solidifying on the inner wall of the slurry recycling device.
[0005] According to one aspect, at least one embodiment of the present invention provides a concrete slurry recycling and mixing device, including an aggregate filter box, a feed pipe fixedly connected to one side of the aggregate filter box, a sludge box fixedly connected to the outer end of the aggregate filter box, a water storage tank fixedly connected to the outer end of the sludge box, and a filter assembly provided inside the aggregate filter box and the sludge box.
[0006] The filtration assembly includes an aggregate filter plate fixedly connected inside the aggregate filter box. The aggregate filter plate has a V-shaped cross-section. An aggregate filter screen is symmetrically fixedly connected inside the aggregate filter plate. A guide pipe is fixedly connected to the outer end of the aggregate filter box. A connecting shaft is rotatably connected between the aggregate filter box and the guide pipe. A feeding auger is fixedly connected to the outer end of the connecting shaft. The feeding auger is rotatably connected inside the aggregate filter plate and the guide pipe.
[0007] The filtration assembly further includes a first filter ring and a second filter ring symmetrically and fixedly connected inside the sludge tank. A first filter screen is fixedly connected inside the first filter ring, and a second filter screen is fixedly connected inside the second filter ring.
[0008] For example, the aperture of the first filter screen is larger than that of the second filter screen, and the filter assembly also includes a first servo motor fixedly connected to the outer end of the aggregate filter box, and the output end of the first servo motor is fixedly connected to the connecting shaft.
[0009] For example, the outer end of the water storage tank is provided with a water pumping assembly, which includes a pump fixedly connected to the outer end of the water storage tank. The bottom end of the pump is fixedly connected to the water storage tank with a water pumping pipe, which is located inside the water storage tank. The top end of the pump is fixedly connected to a water delivery pipe.
[0010] For example, the top of the sludge tank is provided with a driving assembly, which includes an installation pipe fixedly connected to the top of the inner wall of the sludge tank. The bottom end of the installation pipe is fixedly connected to a cavity connection box, and the installation pipe is connected to the cavity connection box. A rotating plate is symmetrically rotatably connected to the outer end of the cavity connection box, and a scraper is fixedly connected to the outer end of the rotating plate. The scraper is in contact with the inner side of the first filter screen and the second filter screen.
[0011] For example, the drive assembly also includes a second servo motor fixedly connected to the top of the sludge tank. The output end of the second servo motor is fixedly connected to a support shaft. The bottom end of the support shaft is fixedly connected to a transmission bevel gear. The bottom end of the transmission bevel gear is symmetrically meshed with a driven bevel gear. The driven bevel gear is fixedly connected to the rotating plate. Both the transmission bevel gear and the driven bevel gear are rotatably connected inside the cavity connecting box.
[0012] For example, the bottom of the sludge tank is provided with a sludge unloading assembly, which includes a unloading box fixedly connected to the bottom of the sludge tank. The sludge tank and the unloading box are connected in communication, and a sludge pipe is fixedly connected to the outer end of the unloading box.
[0013] For example, a third servo motor is fixedly connected to the end of the unloading box away from the sludge pipe, and a sealing plate is fixedly connected to the output end of the third servo motor. A sealing groove is provided inside the unloading box, and the sealing plate is rotatably connected to the inside of the sealing groove.
[0014] For example, a spray pipe is fixedly connected to the top of the aggregate filter box, and a spray head is fixedly connected to the top of the inner cavity of the aggregate filter box. The spray head is provided in several parts and is connected to the spray pipe.
[0015] The beneficial effects of the embodiments of this utility model are as follows:
[0016] In this invention, large aggregate particles are filtered through an aggregate filter screen fixed inside the aggregate filter plate. Simultaneously, the aggregate is transported to the outer end of the aggregate filter box by a feeding auger. The wastewater is then filtered in two stages using a first and a second filter screen, allowing small particles of silt to be collected inside the sludge tank. This multi-stage filtration of the slurry reduces the amount of silt mixed in the wastewater, thereby minimizing the damage to the pump caused by silt and extending the pump's service life. Furthermore, the multi-stage filtration of the slurry results in clearer recycled wastewater. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-3 As shown, it illustrates a concrete slurry recycling and mixing device according to an embodiment of the present invention, including an aggregate filter box 1, a feed pipe 2 fixedly connected to one side of the aggregate filter box 1, a sludge box 3 fixedly connected to the outer end of the aggregate filter box 1, a water storage tank 4 fixedly connected to the outer end of the sludge box 3, and a filter assembly 5 provided inside the aggregate filter box 1 and the sludge box 3.
[0033] The filter assembly 5 includes an aggregate filter plate 501 fixedly connected inside the aggregate filter box 1. The cross-section of the aggregate filter plate 501 is V-shaped. An aggregate filter screen 502 is symmetrically fixedly connected inside the aggregate filter plate 501. A guide pipe 503 is fixedly connected to the outer end of the aggregate filter box 1. A connecting shaft 504 is rotatably connected between the aggregate filter box 1 and the guide pipe 503. A feeding auger 505 is fixedly connected to the outer end of the connecting shaft 504. The feeding auger 505 is rotatably connected inside the aggregate filter plate 501 and the guide pipe 503.
[0034] The filter assembly 5 also includes a first filter ring 506 and a second filter ring 508 symmetrically fixedly connected inside the sludge tank 3. A first filter screen 507 is fixedly connected inside the first filter ring 506, and a second filter screen 509 is fixedly connected inside the second filter ring 508.
[0035] The aperture of the first filter screen 507 is larger than that of the second filter screen 509. The filter assembly 5 also includes a first servo motor 5010 fixedly connected to the outer end of the aggregate filter box 1. The output end of the first servo motor 5010 is fixedly connected to the connecting shaft 504.
[0036] In some examples, the slurry enters the aggregate filter box 1 from the feed pipe 2. At this time, the aggregate filter screens 502, which are symmetrically arranged at the top of the aggregate filter plate 501, perform primary filtration of the slurry. Large aggregate particles are retained inside the aggregate filter plate 501. Simultaneously, the first servo motor 5010 drives the connecting shaft 504 to rotate. At this time, the connecting shaft 504 drives the feeding auger 505 fixed at its outer end to rotate inside the aggregate filter box 1 and the guide pipe 503. The rotating feeding auger 505 discharges large aggregate particles from the guide pipe 503. The wastewater mixed with small particles of mud and sand enters the sludge tank 3 from the inside of the aggregate filter box 1. The wastewater passes through the first filter ring 506 and the second filter ring 508. At this time, the first filter screen 507 and the second filter screen 509 perform secondary filtration of the wastewater, so that small particles of mud and sand are retained inside the sludge tank 3. The relatively clear wastewater enters the water storage tank 4 for storage.
[0037] For example, such as Figure 1 and Figure 5 As shown, a water pumping assembly 6 is provided at the outer end of the water storage tank 4. The water pumping assembly 6 includes a pump 601 fixedly connected to the outer end of the water storage tank 4. A water pumping pipe 602 is fixedly connected between the bottom end of the pump 601 and the water storage tank 4. The water pumping pipe 602 is located inside the water storage tank 4. A water delivery pipe 603 is fixedly connected to the top end of the pump 601.
[0038] In some examples, when recycling and reusing the wastewater inside the water storage tank 4, the pump 601 draws the wastewater inside the water storage tank 4 out of the pump pipe 602 and discharges it out of the water supply pipe 603.
[0039] For example, such as Figures 3-4 As shown, the top of the sludge tank 3 is provided with a drive assembly 7. The drive assembly 7 includes an installation pipe 701 fixedly connected to the top of the inner wall of the sludge tank 3. The bottom end of the installation pipe 701 is fixedly connected to a cavity connection box 702. The installation pipe 701 is connected to the cavity connection box 702. The outer end of the cavity connection box 702 is symmetrically rotatably connected to a rotating plate 703. The outer end of the rotating plate 703 is fixedly connected to a scraper 704. The scraper 704 is in contact with the inner side of the first filter screen 507 and the second filter screen 509.
[0040] The drive assembly 7 also includes a second servo motor 705 fixedly connected to the top of the sludge tank 3. The output end of the second servo motor 705 is fixedly connected to a support shaft 706. The bottom end of the support shaft 706 is fixedly connected to a transmission bevel gear 707. The bottom end of the transmission bevel gear 707 is symmetrically meshed with a driven bevel gear 708. The driven bevel gear 708 is fixedly connected to the rotating plate 703. Both the transmission bevel gear 707 and the driven bevel gear 708 are rotatably connected inside the cavity connecting box 702.
[0041] In some examples, after the first filter screen 507 and the second filter screen 509 perform secondary filtration of wastewater, a lot of silt will adhere to their outer ends, even clogging the pores of the first filter screen 507 and the second filter screen 509, affecting the filtration effect of the wastewater. During secondary filtration of wastewater, the second servo motor 705 drives the support shaft 706 to rotate inside the mounting tube 701. At this time, the transmission bevel gear 707 fixed at the bottom end of the support shaft 706 rotates inside the cavity connecting box 702. The rotating transmission bevel gear Wheel 707 drives two sets of driven bevel gears 708 to rotate simultaneously. The rotating driven bevel gears 708 drive the rotating plate 703 and the scraper 704 at its outer end to rotate. The two sets of rotating scraper 704 clean the first filter screen 507 and the second filter screen 509 respectively to remove the mud and sand attached to the outer ends of the first filter screen 507 and the second filter screen 509. The slurry is treated in multiple stages, so that less waste mud and sand are recovered, reducing the damage caused by mud and sand to the pump 601 and extending the service life of the pump 601.
[0042] like Figure 3 and Figure 6 As shown, it illustrates a concrete slurry recycling and mixing device in another embodiment of the present invention. The bottom end of the sludge tank 3 is provided with a sludge unloading assembly 8. The sludge unloading assembly 8 includes an unloading box 801 fixedly connected to the bottom end of the sludge tank 3. The sludge tank 3 and the unloading box 801 are connected. The outer end of the unloading box 801 is fixedly connected with a sludge pipe 802.
[0043] A third servo motor 803 is fixedly connected to the end of the unloading box 801 away from the sludge pipe 802. A sealing plate 804 is fixedly connected to the output end of the third servo motor 803. A sealing groove is provided inside the unloading box 801, and the sealing plate 804 is rotatably connected to the inside of the sealing groove.
[0044] In some examples, after the slurry undergoes secondary filtration, small particles of silt accumulate at the bottom of the inner cavity of the sludge tank 3. After the wastewater inside the water storage tank 4 is pumped out, the third servo motor 803 drives the sealing plate 804 to rotate in the sealing groove of the unloading box 801. At this time, the silt enters the interior of the unloading box 801 and water can be introduced into the sludge pipe 802, thereby allowing the small particles of silt to be quickly discharged from the unloading box 801.
[0045] For example, such as Figure 7As shown, a spray pipe 9 is fixedly connected to the top of the aggregate filter box 1, and a spray head 10 is fixedly connected to the top of the inner cavity of the aggregate filter box 1. The spray head 10 is provided in several parts and is connected to the spray pipe 9.
[0046] In some examples, after the slurry is filtered in the first stage, concrete and small particles of mud and sand still adhere to the outer ends of the large aggregate particles. At this time, clean water is introduced into the spray pipe 9 and sprayed out from the spray head 10. The sprayed clean water washes the large aggregate particles. At the same time, clean water can also be poured into the spray pipe 9 to clean the inside of the aggregate filter box 1, sludge box 3 and water storage box 4.
[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
