Description

Technical Field

[0001] The present invention relates to the technical field of construction wastewater treatment equipment, and in particular to a construction wastewater treatment device and a use method thereof. Background Art

[0002] Construction sites often generate a lot of construction wastewater, which contains a large amount of mud, sand and gravel, and direct discharge will cause pollution. In the prior art, the construction wastewater needs to be pumped into a water tank or pool through a water pump, and then the construction wastewater in the pool will be layered after being sprayed with flocculants and left to stand for a period of time. The upper layer is the separated sewage, and the lower layer is the separated construction mud and sand. The separated sewage and mud can be recycled for secondary utilization after treatment. However, there are the following problems: first, the method of spraying flocculants is too single and not comprehensive enough, resulting in insufficient mixing of construction wastewater and flocculants. The static stratification time is long and the stratification effect is poor; secondly, when the sewage and the construction mud are stratified, the sewage in the pool needs to be discharged to the outside first, and then the construction mud in the pool needs to be taken out for subsequent recycling treatment. However, it is easy to discharge the construction mud in the pool at the same time as the sewage is discharged, resulting in a waste of construction mud; there is a lack of a device that can ensure that the flocculant is put in more comprehensively and the flocculant and the construction wastewater are mixed more fully, thereby improving the efficiency of static stratification of construction wastewater, and classify and discharge the construction wastewater and construction mud separately after stratification, and minimize the degree of mixing between the two during the discharge process.

[0010] Preferably, the method for using the construction wastewater treatment device comprises the following steps:

[0011] S1: When the device is in use, the construction wastewater on the construction site is first pumped into the treatment water tank through a water pump. In the initial state, the drainage port and the discharge port at the side end of the treatment water tank are sealed and closed by the drainage device and the closing component respectively. The full spraying device is driven to work by controlling the driving component. The spraying device is driven to move from the diagonal position on one side of the top surface of the treatment water tank to the diagonal position on the other side of the treatment water tank through the driving of the full spraying device, and the movement of the spraying device is an oblique motion trajectory. During the movement of the spraying device, the flocculant is sprayed on the inside of the treatment water tank, thereby spraying the flocculant on the inside of the treatment water tank in all directions;

[0012] S2: When the spraying equipment moves obliquely to deliver the flocculant into the treatment water tank, the driving component synchronously drives the output end of the mixing and discharging device to move from one end of the treatment water tank to the other end, and the moving trajectory is wavy and the device itself moves in a circular motion, thereby fully mixing the flocculant delivered into the treatment water tank with the construction wastewater, and the moving speed of the output end of the mixing and discharging device is consistent with the moving speed of the spraying equipment;

[0013] S3: After the flocculant is added and mixed with the construction wastewater, it is left to stand for a period of time so that the construction wastewater inside the treatment tank is layered, with the upper layer being sewage and the lower layer being construction mud. At this time, the drainage device is controlled to work, and the drainage port at the top is first opened to discharge the sewage at the uppermost layer inside the treatment tank. When the sewage is almost discharged, the drainage port at the bottom is opened, and so on, all the drainage ports are gradually opened. When the sewage is discharged and approaches the construction mud at the lower layer, the drainage port is closed, and the construction sewage flows into the water storage tank to wait for subsequent treatment;

[0014] S4: When all the construction sewage inside the treatment water tank is discharged, the control drive component drives the spraying equipment to reset to the initial position. During the resetting process, the output end of the mixing and discharging device is driven to reset and move toward the discharge port, and the discharge port is opened by the closing component. At this time, the output end of the mixing and discharging device moves in a straight line and pushes the construction mud and sand at the bottom of the treatment water tank from the discharge port to the outside of the treatment water tank and falls into the storage box to complete the collection.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the driving motor is controlled to drive the second screw to rotate clockwise, and the first screw is driven to rotate synchronously under the transmission of the pulley and the transmission belt. The rotation of the first screw drives the slide rod to move along the first screw, and the second bevel gear is driven to rotate under the action of the first bevel gear, thereby driving the sliding rod to slide along the third screw, so that the spraying equipment arranged at the bottom of the driving block moves from the diagonal position on one side of the top surface of the treatment water tank to the diagonal position on the other side of the treatment water tank, and the movement of the spraying equipment presents an oblique motion trajectory. During the movement of the spraying equipment, flocculant is sprayed on the inside of the treatment water tank, thereby achieving an effect of all-round flocculant spraying on the inside of the treatment water tank.

[0017] In the present invention, when the construction wastewater inside the treated water tank is stratified and the sewage in the upper layer of the construction wastewater needs to be discharged, the first electric push rod is first controlled to drive the first toothed rod to slide in the direction of the first gear, and the drainage outlet at the top is exposed after sliding for a distance. As the drainage outlet is gradually exposed, the construction sewage in the upper layer of the treated water tank is gradually discharged at a moderate speed. When the drainage outlet at the top no longer discharges sewage, the first toothed rod is controlled to continue to slide in the direction of the first gear to drive the first gear to rotate, thereby driving the second toothed rod to move in the direction opposite to the moving direction of the first toothed rod, thereby making the drainage opening on the second toothed rod gradually correspond to the position of the drainage outlet adjacent to it. After complete correspondence, the movement of the second toothed rod is stopped, and the sewage inside the treated water tank continues to be discharged. When this drainage outlet no longer discharges sewage, the second toothed rod is moved to the left by the first electric push rod. When the cam is in contact with the second gear, the third toothed rod is driven to move in the opposite direction to the second toothed rod, so that the drainage opening on the third toothed rod and the drainage opening adjacent to it gradually correspond to each other. After they are completely matched, the movement of the third toothed rod is stopped, and the sewage inside the treatment water tank is continued to be discharged. While discharging, it is observed whether the sewage inside the treatment water tank is discharged cleanly or close to the boundary between sewage and mud. If the drainage port is no longer draining and the internal sewage has not been discharged cleanly, the third toothed rod is continuously controlled to move by the first electric push rod to contact the third gear and drive the fourth toothed rod to move in the opposite direction to the third toothed rod, so that the drainage opening on the fourth toothed rod and the drainage opening adjacent to it gradually correspond to each other, and the sewage is continued to be discharged. When all the sewage is discharged, the movement of the fourth toothed rod is stopped, thereby realizing the complete drainage of the sewage inside the treatment water tank and avoiding the problem of discharging construction mud and sand together.

[0018] In the present invention, when the spraying equipment moves from one end of the treatment water tank to the other end, the second screw is driven to rotate synchronously under the transmission of the first screw, the pulley and the transmission belt, thereby driving the sliding frame to move from one end of the moving frame to the other end, so that the sliding frame drives the sliding block to move along the wave shape of the upper part of the driving groove while sliding up and down on the sliding frame during the movement, thereby driving the mixing plate to move in a wave-shaped trajectory from one end to the other end inside the treatment water tank, and as the sliding block slides up and down, the fourth gear is driven to rotate under the action of the fifth toothed rod, so that the mixing plate generates a reciprocating circular motion while moving in a wave-shaped trajectory, thereby achieving full mixing of the flocculant and the construction wastewater put into the treatment water tank, and the mixing and flocculant are mixed. The addition is synchronous and carried out on the same trajectory, so that the flocculant and construction wastewater are mixed more fully, thereby shortening the static stratification time of construction wastewater; when the sewage inside the treatment water tank is discharged, the spraying equipment is controlled to reset to the initial position, and the sliding frame is driven to slide toward the discharge port on the moving frame during the reset process. At this time, according to the lower end trajectory of the driving groove, the mixing plate is controlled to descend a certain distance in a vertical state and the bottom is in contact with the bottom of the treatment water tank, and slides in a straight line toward the discharge port. At this time, the second electric push rod is controlled to work to drive the closing plate to rise to expose the discharge port, and then the mud and sand at the lower end of the treatment water tank and the mud and sand adhering to the bottom are all pushed out to the outside of the discharge port through the movement of the mixing plate and fall into the storage box to complete collection, waiting for subsequent recycling and processing.

[0037] After the sewage in the treatment tank 2 is stratified, it is necessary to discharge the sewage in the upper layer of the construction sewage. First, the first electric push rod 71 is controlled to drive the first toothed rod 72 to slide in the direction of the first gear 76. After sliding for a distance, the drainage outlet 6 at the top is exposed. As the drainage outlet 6 is gradually exposed, the construction sewage in the upper layer of the treatment tank 2 is gradually discharged at a moderate speed.

While discharging, it is observed whether the sewage inside the treatment water tank 2 is discharged cleanly or close to the dividing line between sewage and mud. If the drainage opening 6 no longer drains and the internal sewage has not been discharged cleanly, the third toothed rod 74 is continued to be controlled by the first electric push rod 71 to move so that it contacts the third gear 78 and drives the fourth toothed rod 75 to move in the opposite direction to the third toothed rod 74, so that the drainage opening 79 on the fourth toothed rod 75 and the adjacent drainage opening 79 gradually correspond to each other, and the sewage is continued to be discharged. When the sewage is completely discharged, the movement of the fourth toothed rod 75 is stopped, so that the sewage inside the treatment water tank 2 is completely drained, and the problem of discharging construction mud and sand together is avoided.

[0039] The closing assembly 10 includes a second electric push rod 101 and a closing plate 102, wherein the closing plate 102 is arranged outside the treatment water tank 2 and closes the discharge port 9, and the closing plate 102 is connected to the side end of the treatment water tank 2 by sliding up and down, and the second electric push rod 101 is vertically arranged at the side end of the treatment water tank 2 and the output end of the second electric push rod 101 is connected to the top of the closing plate 102;

[0040] When the spraying device 5 moves from one end of the treatment water tank 2 to the other end, the second screw 36 is driven to rotate synchronously under the transmission of the first screw 35, the pulley 33 and the transmission belt 34, thereby driving the sliding frame 83 to move from one end of the moving frame 81 to the other end, so that the sliding frame 83 drives the sliding block 84 to move along the wave-shaped movement of the upper part of the driving groove 82 during the movement, while sliding up and down on the sliding frame 83, thereby driving the mixing plate 87 to move in a wave-shaped trajectory from one end to the other end inside the treatment water tank 2, and as the sliding block 84 slides up and down, the fourth gear 86 is driven to rotate under the action of the fifth toothed rod 85, so that the mixing plate 87 generates a reciprocating circular motion while moving in a wave-shaped trajectory, thereby achieving full mixing of the flocculant and the construction wastewater placed in the treatment water tank 2, and the mixing and flocculant mixing is achieved.

[0041] The use method and advantages of the present invention: The use method of the construction wastewater treatment device, the working process is as follows:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown:

[0043] S1: When the device is in use, the construction wastewater on the construction site is first pumped into the treatment water tank 2 by a water pump. In the initial state, the drainage port 6 and the discharge port 9 at the side end of the treatment water tank 2 are sealed and closed by the drainage device 7 and the closing component 10 respectively. The driving component 3 is controlled to drive the full spraying device 4 to work. The full spraying device 4 is driven to drive the spraying device 5 to move from the diagonal position on one side of the top surface of the treatment water tank 2 to the diagonal position on the other side of the treatment water tank 2, and the movement of the spraying device 5 is an oblique motion trajectory. During the movement of the spraying device 5, the flocculant is sprayed on the inside of the treatment water tank 2, thereby spraying the flocculant on the inside of the treatment water tank 2 in all directions;

[0044] S2: When the spraying device 5 moves obliquely to deliver the flocculant into the treatment water tank 2, the driving component 3 synchronously drives the output end of the mixing and discharging device 8 to move from one end of the treatment water tank 2 to the other end, and the moving trajectory is wavy and the device itself moves in a circular motion, so that the flocculant delivered into the treatment water tank 2 is fully mixed with the construction wastewater, and the moving speed of the output end of the mixing and discharging device 8 is consistent with the moving speed of the spraying device 5;

[0045] S3: After the flocculant is added and mixed with the construction wastewater, it is left to stand for a period of time so that the construction wastewater in the treatment water tank 2 is stratified, with the upper layer being sewage and the lower layer being construction mud. At this time, the drainage device 7 is controlled to work, and the drainage port 6 at the top is first opened to discharge the sewage at the upper layer in the treatment water tank 2. When the sewage is almost discharged, the drainage port 6 at the bottom is opened, and so on, all the drainage ports 6 are gradually opened. When the sewage is discharged and approaches the construction mud at the lower layer, the drainage port 6 is closed, and the construction sewage flows into the water storage tank 11 to wait for subsequent treatment;

[0046] S4: When all the construction sewage inside the treatment water tank 2 is discharged, the control driving component 3 drives the spraying equipment 5 to reset to the initial position. During the resetting process, the output end of the mixing and discharging device 8 is driven to reset and move toward the discharge port 9, and the discharge port 9 is opened through the closing component 10. At this time, the output end of the mixing and discharging device 8 moves in a straight line and pushes the construction mud and sand at the bottom of the treatment water tank 2 from the discharge port 9 to the outside of the treatment water tank 2 and falls into the storage box 12 to complete the collection.
