Description

Technical Field

[0001] This utility model relates to the field of calcium silicate board production, and in particular to a wastewater recycling system for calcium silicate board production. Background Technology

[0002] Calcium silicate board is a new type of inorganic building material made primarily from siliceous materials such as quartz sand and fly ash, and calcareous materials such as cement and lime, with added fiber reinforcement materials such as asbestos and pulp. The process involves pulping, molding, and autoclaving. The production and processing of calcium silicate board generates a large amount of wastewater during the raw material preparation stage (pulping and washing), the board dewatering stage (molding), and the equipment cleaning and floor washing processes.

[0003] In related technologies, in order to improve economic efficiency and conform to the development concept of green production and circular economy, a wastewater recycling system is usually adopted to recycle and treat the wastewater generated in the production process of calcium silicate board. The traditional wastewater recycling system usually consists of three parts: pretreatment, purification treatment and reuse pipeline network. In the pretreatment stage, coarse impurities and most of the suspended solids in the wastewater are usually removed by sedimentation tank. Then, the sedimentation-treated wastewater is pumped and transported to other treatment equipment by water pump and pipeline to reduce the risk of blockage in subsequent equipment.

[0004] However, when wastewater is pumped through pipes, the sediment in the wastewater is prone to floating, which may affect the sedimentation treatment effect of the wastewater.

[0005] Therefore, it is necessary to provide a wastewater recycling system for calcium silicate board production to solve the above problems. Utility Model Content

[0006] To address the technical problem that sediments in wastewater tend to float during the pumping process through pipelines, potentially affecting the sedimentation treatment effect, this invention provides a wastewater recycling system for calcium silicate board production.

[0007] The wastewater recycling system for calcium silicate board production provided by this utility model includes: a wastewater recycling treatment tank, with a partition plate fixedly connected to the inner wall of the wastewater recycling treatment tank. One side of the partition plate is a sedimentation chamber, and the other side of the partition plate is a water collection chamber. An overflow outlet is provided on the upper surface of the partition plate. Multiple sedimentation interceptors are provided, and the multiple sedimentation interceptors are fixedly arranged in layers on one side of the partition plate. The sedimentation interceptors are located inside the water collection chamber. Multiple sludge guides are evenly provided on the partition plate, and each sludge guide is connected to each sedimentation interceptor. The interceptor includes symmetrically arranged triangular mounting plates, one side of which is fixedly connected to one side of the partition plate. An overflow plate is fixedly connected between the symmetrically arranged triangular mounting plates. The overflow plate is inclined and its bottom is fixedly connected to one side of the partition plate. The width of the overflow plate in the plurality of sediment interceptors increases sequentially from top to bottom. A hydraulic cylinder is fixedly installed on the top of the inner wall of the partition plate. An adjusting plate is fixedly connected to the output end of the hydraulic cylinder. The outer wall of the adjusting plate is slidably connected to the inner wall of the partition plate for controlling the opening and closing of the plurality of sewage outlets.

[0008] Preferably, a filter plate located inside the overflow outlet is fixedly connected to the inner wall of the partition plate.

[0009] Preferably, the wastewater recycling treatment tank includes a rectangular box body, a protective cover is movably connected to the upper surface of the rectangular box body, an inlet pipe connected to the sedimentation chamber is fixedly connected to one side of the rectangular box body, and a drain pipe connected to the water collection chamber is fixedly connected to the other end of the rectangular box body. The drain pipe is located below the plurality of sedimentation interceptors.

[0010] Preferably, the adjusting plate includes a rectangular plate, the output end of the hydraulic cylinder is fixedly connected to the upper surface of the rectangular plate, and a plurality of communication ports are evenly provided on the adjusting plate.

[0011] Preferably, a first drain pipe connected to the sedimentation chamber is fixedly connected to one side of the rectangular box, and the first drain pipe is located below the water inlet pipe.

[0013] Compared with related technologies, the wastewater recycling system for calcium silicate board production provided by this utility model has the following beneficial effects:

[0014] 1. This calcium silicate board production wastewater recycling system can improve the sedimentation effect: by setting multiple sedimentation interceptors in layers, and with the overflow plate width gradually increasing from top to bottom, the water flow can pass through each sedimentation interceptor in sequence for stratified sedimentation. This design increases the sedimentation path and time of the wastewater, which can more fully separate impurities and sediments in the wastewater, improve the sedimentation treatment effect of the wastewater, and make the wastewater collected in the collection chamber clearer, providing a good foundation for subsequent wastewater recycling and reducing the burden on subsequent treatment equipment;

[0015] 2. This calcium silicate board production wastewater recycling system uses a hydraulic cylinder to drive an adjusting plate to control the opening and closing of the sewage guide port. The sewage guide port is closed during normal sedimentation and opened during sludge removal and cleaning. The protective cover can be opened and closed, facilitating personnel to inspect and clean the inside of the rectangular box. The water supply pipe and spray head allow for water spraying and rinsing of the inside of the box during cleaning, improving cleaning efficiency. The first and second sewage discharge pipes can discharge sewage from the sedimentation chamber and the water collection chamber respectively, making sewage discharge more convenient and faster.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 6 A wastewater recycling system for calcium silicate board production includes: a wastewater recycling tank 1; a partition plate 2 is fixedly connected to the inner wall of the wastewater recycling tank 1; one side of the partition plate 2 is a sedimentation chamber 3, and the other side of the partition plate 2 is a water collection chamber 4; an overflow outlet 5 is provided on the upper surface of the partition plate 2; multiple sedimentation interceptors 6 are provided, and the multiple sedimentation interceptors 6 are fixedly arranged in layers on one side of the partition plate 2. The sedimentation interceptors 6 are located inside the water collection chamber 4; multiple sewage guides 7 are evenly provided on the partition plate 2, and each sewage guide 7 is connected to each sedimentation interceptor 6; the sedimentation interceptor 6 includes symmetrically arranged triangular mounting plates 601. One side of the triangular mounting plate 601 is fixedly connected to one side of the partition plate 2. An overflow plate 602 is fixedly connected between the symmetrically arranged triangular mounting plates 601. The overflow plate 602 is inclined and its bottom is fixedly connected to one side of the partition plate 2. The width of the overflow plate 602 in the multiple sediment interception components 6 increases from top to bottom to facilitate the water flow through the multiple sediment interception components 6. The hydraulic cylinder 8 is fixedly installed on the top of the inner wall of the partition plate 2. An adjusting plate 9 is fixedly connected to the output end of the hydraulic cylinder 8. The outer wall of the adjusting plate 9 is slidably connected to the inner wall of the partition plate 2 for controlling the opening and closing of the multiple sewage outlets 7.

[0025] In the specific implementation process, the wastewater recycling tank 1 in the calcium silicate board production wastewater recycling system is divided into two areas, a sedimentation chamber 3 and a water collection chamber 4, by a fixedly connected partition plate 2. The sedimentation chamber 3 is mainly used to receive the wastewater from the initial calcium silicate board production and to perform preliminary sedimentation on the wastewater. An overflow port 5 is provided on the upper surface of the partition plate 2. When the water level in the water collection chamber 4 reaches the preset height, the wastewater after sedimentation treatment can be discharged into the water collection chamber 4 through the overflow port 5.

[0026] Furthermore, multiple sedimentation interceptors 6 are uniformly and fixedly connected to one side of the partition plate 2, arranged in layers. Each sedimentation interceptor 6 consists of a symmetrically arranged triangular mounting plate 601 and an overflow plate 602 installed between the symmetrically arranged triangular mounting plates 601. The width of the overflow plate 602 in the multiple sedimentation interceptors 6 increases from top to bottom, so that the water overflowing from the overflow port 5 can flow through each sedimentation interceptor 6 in the height direction for layered sedimentation treatment, thereby improving the sedimentation effect of the wastewater. The sedimented wastewater can be collected in the water collection chamber 4, and then pumped and transported to the wastewater recycling treatment equipment in other stages by a water pump and pipeline. The method of directly pumping the wastewater in the water collection chamber 4 through the pipeline can minimize the floating of sediment, thereby improving the sedimentation treatment effect of the wastewater.

[0027] Furthermore, multiple sludge guide ports 7 are evenly provided on the partition plate 2, corresponding to each sedimentation interceptor 6. An adjusting plate 9 is installed inside the partition plate 2 via a hydraulic cylinder 8. Activating the hydraulic cylinder 8 can drive the adjusting plate 9 to move up and down. The movement of the adjusting plate 9 can synchronously control the opening and closing of multiple sludge guide ports 7. When sedimentation is required, the adjusting plate 9 is controlled to move down to close the sludge guide ports 7, allowing the sedimentation interceptor 6 to perform sedimentation interception. When sludge removal and cleaning of the sedimentation interceptor 6 is required, the water level inside the sedimentation chamber 3 needs to be lowered to below the sludge guide ports 7. Then, the adjusting plate 9 is controlled to move up to open the sludge guide ports 7, allowing the sediment to be discharged into the sedimentation chamber 3 with the water flow, so that it can be cleaned together with the sediment in the sedimentation chamber 3.

[0028] Specifically, it should be noted that the hydraulic cylinder 8 is a device with relatively mature existing technology. The specific model can be selected according to actual needs. The hydraulic cylinder 8 also needs to cooperate with power sources such as gear pumps or piston pumps to provide driving force. It needs to cooperate with control structures such as pressure valves, flow valves, and controllers to achieve extension and retraction control. The hydraulic cylinder 8 can also be replaced with drive devices such as electric actuators that can be reciprocated and adjusted, depending on the usage requirements.

[0029] See Figure 2 and Figure 4 As shown, a filter plate 10 located inside the overflow outlet 5 is fixedly connected to the inner wall of the partition plate 2.

[0030] In the specific implementation process, the filter plate 10 can perform certain filtration treatment on the wastewater flowing through the overflow outlet 5, thereby improving the wastewater treatment effect.

[0031] See Figure 1 and Figure 2 As shown, the wastewater recycling treatment tank 1 includes a rectangular box 101. A protective cover 102 is movably connected to the upper surface of the rectangular box 101. An inlet pipe 103 connected to the sedimentation chamber 3 is fixedly connected to one side of the rectangular box 101. A drain pipe 104 connected to the water collection chamber 4 is fixedly connected to the other end of the rectangular box 101. The drain pipe 104 is located below multiple sedimentation interceptors 6.

[0032] In the specific implementation process, the rectangular box 101 can restrict the installation position of the partition plate 2, and the protective cover 102 can be opened and closed as needed, so as to facilitate personnel to inspect and clean the inside of the rectangular box 101. The water inlet pipe 103 can be connected to the conveying mechanism as needed to transport wastewater into the rectangular box 101. The drain pipe 104 can be connected to the pumping equipment as needed to transport the settled wastewater to other treatment stages.

[0033] See Figure 3 , Figure 4 and Figure 6 As shown, the adjusting plate 9 includes a rectangular plate 901, the output end of the hydraulic cylinder 8 is fixedly connected to the upper surface of the rectangular plate 901, and multiple connecting ports 902 are evenly provided on the adjusting plate 9.

[0034] In the specific implementation process, when the hydraulic cylinder 8 is started, the rectangular plate 901 can be adjusted to move up and down. The position of the connecting port 902 can be adjusted by the movement of the rectangular plate 901. When the connecting port 902 is connected to the sewage guide port 7, it is convenient for the sediment interceptor 6 to discharge sewage.

[0035] See Figure 1 and Figure 2 As shown, a first drain pipe 13 connected to the sedimentation chamber 3 is fixedly connected to one side of the rectangular box 101. The first drain pipe 13 is located below the water inlet pipe 103. A second drain pipe 14 connected to the water collection chamber 4 is fixedly connected to the other end of the rectangular box 101. The second drain pipe 14 is located below the drain pipe 104.

[0036] In the specific implementation process, when cleaning the inside of the sedimentation chamber 3, sewage can be discharged outward through the first sewage pipe 13, and when cleaning the inside of the water collection chamber 4, sewage can be discharged outward through the second sewage pipe 14.

[0037] Specifically, it should be noted that control valves can be installed on the first sewage pipe 13 and the second sewage pipe 14 as needed to facilitate sewage discharge control.

[0038] See Figure 2 As shown, a water supply pipe 11 is fixedly connected inside the protective cover 102, and multiple water spray heads 12 are evenly fixedly connected to the bottom of the water supply pipe 11.

[0039] In the specific implementation process, one end of the water supply pipe 11 can be connected to the water source through a water pump. Starting the water pump can deliver the water source to multiple spray nozzles 12 through the water supply pipe 11. The multiple spray nozzles 12 can spray water into the rectangular box 101 to rinse it, so as to reduce the cleaning difficulty.

[0040] The working principle of the wastewater recycling system for calcium silicate board production provided by this utility model is as follows:

[0041] When the wastewater recycling system for calcium silicate board production is in operation, the wastewater enters the sedimentation chamber 3 of the wastewater recycling treatment tank 1 through the inlet pipe 103 for preliminary sedimentation. The partition plate 2 divides the wastewater recycling treatment tank 1 into the sedimentation chamber 3 and the collection chamber 4. The upper surface of the partition plate 2 is provided with an overflow port 5. The settled wastewater flows into the collection chamber 4 through the overflow port 5. The filter plate 10 in the overflow port 5 performs preliminary filtration of the wastewater. Multiple sedimentation interceptors 6 are arranged in layers, and the width of their overflow plates 602 increases from top to bottom. The water flows through each sedimentation interceptor 6 in sequence for stratified sedimentation. The hydraulic cylinder 8 drives the adjusting plate 9 to move up and down. During normal sedimentation, the adjusting plate 9 moves down to close the sewage outlet 7, and the sedimentation interceptors 6 intercept some of the sediment. During sludge removal and cleaning, the water level in the sedimentation chamber 3 is lowered to below the sewage outlet 7, and the adjusting plate 9 moves up to open the sewage outlet 7. The sediment in the sedimentation interceptors 6 is discharged into the sedimentation chamber 3 with the water flow. The wastewater in the collection chamber 4 is pumped and transported to other wastewater recycling treatment equipment through the drain pipe 104.
