Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater recycling and purification device for concrete production. Background Technology

[0002] With the acceleration of urbanization and the large-scale advancement of infrastructure construction, the production of concrete, as a core material in construction projects, has been increasing year by year. However, the concrete production process generates a large amount of wastewater containing a large number of sand and gravel particles, cement slurry, and other impurities. If discharged directly without treatment, it will not only cause a serious waste of water resources but also lead to a series of environmental problems such as soil compaction and water pollution. According to statistics, my country discharges tens of millions of tons of wastewater annually due to concrete production, posing a huge pressure on the ecological environment.

[0003] Currently, most concrete mixing plants use relatively simple and rudimentary wastewater treatment methods. Traditional sedimentation tank treatment processes suffer from low filtration efficiency, large footprint, and difficulty in slag removal, making it difficult to meet increasingly stringent environmental emission standards. Furthermore, existing treatment equipment requires significant manual intervention, resulting in high operating costs. Utility Model Content

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a concrete production wastewater recycling and purification device, comprising:

[0027] The feeding assembly 100 includes a housing 101, a hopper 102 fixedly connected to one side of the end of the housing 101, a main screen plate 103 inserted in the middle of the hopper 102, and a guide plate 104 fixedly connected to the inner wall of the hopper 102, with the end of the guide plate 104 inserted into the end side wall of the main screen plate 103.

[0028] The feeding assembly 200 includes a secondary screen plate 201 inserted in the middle of the housing 101, an inclined plate 202 inserted in the inner wall of the housing 101, a cover plate 203 fixedly connected to the other side of the end of the housing 101, and a diversion plate 204 installed at the lower end of the cover plate 203. The bottom of the diversion plate 204 is fixedly connected to the inner wall of the housing 101. The secondary screen plate 201 is installed below the main screen plate 103, and the end of the secondary screen plate 201 extends above the end of the diversion plate 204.

[0029] The feeding assembly 100 serves as the wastewater inlet unit. Its housing 101 is welded from Q235 carbon steel, with an epoxy resin anti-corrosion coating sprayed on the inner wall. The hopper 102 is sealed to the end of the housing 101 via a flange, forming a funnel-shaped feeding channel. The main screen plate 103 is made of 304 stainless steel perforated plate and is slidably inserted into the middle of the hopper 102 via a slot structure, which can intercept larger particles of impurities. The end of the guide plate 104 is inserted into the slot on the side wall of the main screen plate 103 and welded and sealed to the inner wall of the hopper 102, forming a guide channel. The feeding assembly 200 is responsible for the transportation and secondary filtration of wastewater. The secondary screen plate 201 is fixed in the middle of the housing 101 via a slot, located directly below the main screen plate 103, and is used to intercept fine particles. The inclined plate 202 is welded to the inner wall of the housing 101 at an angle, with a smooth surface to facilitate the sliding of sediment. The cover plate 203 is fixed to the other side of the end of the housing 101 with bolts, forming a closed channel. The diversion plate 204 is made of stainless steel plate bent into shape. The bottom is welded to the inner wall of the box 101, and the top extends to the bottom of the cover plate 203 to form a diversion channel.

[0030] Specifically, the feeding assembly 200 also includes a push plate 205 that is slidably inserted into the side wall of the diversion plate 204. The push plate 205 is slidably installed inside the housing 101. The feeding assembly 200 also includes a push rod 206 that is fixedly connected to the inner wall of the housing 101. The end of the push rod 206 is fixedly connected to the end of the push plate 205.

[0031] The push plate 205 is made of rubber sealing plate and is slidably installed on the side wall of the diversion plate 204 through the slider guide rail mechanism, and is sealed to the inner wall of the box 101. The push rod 206 is an electric push rod, with the fixed end installed on the inner wall of the box 101 by bolts, and the telescopic end welded to the end of the push plate 205 to realize the reciprocating motion of the push plate 205.

[0032] Furthermore, the feeding assembly 200 also includes a baffle 207 inserted into the inner side of the end of the cover plate 203. The baffle 207 has a handle installed on its side wall, and its end extends to the outer side wall of the hopper 102. The baffle 207 is also engaged above the housing 101.

[0033] The baffle 207 is inserted into the inner side of the cover plate 203 through a slot, and its end extends to the outer wall of the hopper 102. It is used to close the connection and facilitates opening for cleaning and maintenance of the device. A plastic handle is installed on the surface for easy manual operation.

[0034] Preferably, the main screen plate 103 has a slot structure on its side wall that works with the guide plate 104, and the side wall of the guide plate 104 is sealed and inserted into the inner wall of the hopper 102. The feeding assembly 100 also includes a main shaft 105 rotatably mounted on the side wall of the hopper 102, and a scraper 106 fixedly connected to the side wall of the main shaft 105. The end of the scraper 106 is inserted into the inner side of the middle through groove of the main screen plate 103. The feeding assembly 100 also includes a motor 107 fixedly connected to the outside of the hopper 102. The output end of the motor 107 is connected to the main shaft 105 through a reducer.

[0035] The main shaft 105 is rotatably mounted on the side wall of the hopper 102 via a deep groove ball bearing, and four sets of scrapers 106 are evenly distributed on its surface. The scrapers 106 are made of polyurethane elastomer, and their ends are embedded in the through grooves of the main screen plate 103, maintaining a gap with the surface of the screen plate. The motor 107 is connected to the input shaft of the reducer via a flexible coupling, and the output shaft of the reducer is connected to the main shaft 105 via a flat key to drive the rotation of the scrapers 106.

[0036] In operation, when concrete production wastewater is injected from the top of hopper 102, it first passes through the main screen plate 103 for filtration, intercepting larger sand and gravel particles. Motor 107 drives the main shaft 105 to rotate, causing scraper 106 to slide on the surface of the main screen plate 103, pushing the intercepted impurities to guide plate 104, which then discharges the wastewater from the tank 101. The pre-filtered wastewater falls to the secondary screen plate 201 for secondary filtration, intercepting finer particles. After two filtrations, the wastewater slides down inclined plate 202 and enters the water collection area at the bottom of the tank 101. During the wastewater flow, some sediment adheres to the surface of inclined plate 202 and gradually slides down to the bottom of the tank 101. Periodically, electric push rod 206 is activated, driving push plate 205 to slide on the surface of diversion plate 204, pushing the sediment towards the slag discharge port at the end of the tank 101 for discharge. By pulling the handle on baffle 207, the opening size at the end of cover plate 203 can be adjusted to control the flow rate and volume of the wastewater. The purified wastewater is discharged from the outlet at the bottom of the tank 101 and can be recycled for concrete production.

[0037] In summary, the two-stage filtration of the main screen plate 103 and the secondary screen plate 201, combined with the sedimentation effect of the inclined plate 202, effectively removes large particulate impurities and fine sediments from wastewater, achieving a purification efficiency of over 95%. The automatic slag discharge design of the scraper 106 and pusher plate 205 prevents screen plate clogging, enabling continuous operation of the device, improving production efficiency, and reducing manual slag removal workload. The main screen plate 103, secondary screen plate 201, and baffle 207 all feature a detachable connection design for easy replacement and cleaning.
