Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically to a silicon-containing wastewater treatment device. Background Technology

[0002] Wastewater refers to waste water generated in industry or daily life. Among them, industrial wastewater treatment is the most complex. Silicon-containing industrial wastewater refers to wastewater generated in the silicon industry during the cutting process. Due to scouring, this type of wastewater contains a large amount of silicon and diamond powder, making it relatively complicated to treat.

[0003] Currently, the coagulation media used in wastewater treatment are generally directly added to the water surface and then stirred and mixed independently. This method results in poor feeding effect, uneven mixing of the media and wastewater, and requires a certain amount of time. In particular, the mixing effect of wastewater in deeper areas is far less than that of wastewater near the top. Therefore, a silicon-containing wastewater treatment device is proposed here. Utility Model Content

[0004] The technical problem this invention aims to solve is that the mixing effect between wastewater and coagulation media is currently poor, especially for wastewater with a deeper water level, which seriously delays the wastewater treatment efficiency. This invention provides a silicon-containing wastewater treatment device that can simultaneously perform coagulation treatment on wastewater at different water levels, thereby improving the coagulation treatment effect and increasing the wastewater treatment efficiency.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a silicon-containing wastewater treatment device, including a coagulation tank, a filter tank fixedly connected to one side wall of the coagulation tank, a sedimentation tank set on the side of the coagulation tank away from the filter tank, an inner cavity opened inside the coagulation tank, the inner cavity having a cylindrical structure, a main shaft rotatably connected to the middle of the bottom side wall of the inner cavity, a row of support arms fixedly connected to both side walls of the main shaft, the two rows of support arms being staggered, and a discharge port being opened through one side wall of each support arm.

[0006] As a preferred embodiment of this utility model, both the main shaft and the support arm are hollow cylindrical structures, the support arm and the main shaft are internally connected, and the discharge port is rotatably connected to a check plate via a torsion spring, and the torsion spring is a unidirectional rotation structure.

[0007] As a preferred technical solution of this utility model, a drive motor is detachably embedded in the top side wall of the coagulation tank, and the output end of the drive motor extends into the inner cavity and is detachably connected to a drive gear. A driven gear is meshed with one side of the drive gear, and the driven gear is rotatably connected to the top side wall of the inner cavity. The main shaft is inserted and fixedly connected in the middle of the driven gear.

[0008] As a preferred technical solution of this utility model, a storage tank is detachably connected to the top of the coagulation tank and the side wall away from the drive motor by screws. A conveying pipe is fixedly connected to the side wall of the storage tank near the bottom edge, and the conveying pipe has an L-shaped structure. One end of the main shaft passes through the top side wall of the coagulation tank and is sleeved on the end of the conveying pipe away from the storage tank.

[0009] As a preferred technical solution of this utility model, a water inlet groove is provided through one side wall at the bottom of the coagulation tank, and a water outlet tank is fixedly connected to the side wall of the coagulation tank away from the water inlet groove. The coagulation tank is connected to one side wall of the sedimentation tank through the water outlet tank, and a drain outlet is provided through one side of the sedimentation tank away from the coagulation tank and near the top edge.

[0010] As a preferred technical solution of this utility model, three pairs of side grooves are provided on the opposite side walls of the filter box. Filter plates are inserted into the side grooves. The filter plates are divided into three pieces, and the filter hole size on the three filter plates gradually decreases. A cover plate is detachably connected to the top of the filter plate by a snap fastener. An outlet is provided through the side wall of the filter box opposite to the water inlet tank. The filter box and the coagulation tank are connected to the water inlet tank through the outlet.

[0011] This invention has the following advantages: The medium is fed into the storage tank, then into the main shaft through the conveying pipe. Wastewater is fed into the filter box through a pipe fixed to one side wall of the filter box. The wastewater is filtered by three filter plates, and then fed into the coagulation tank through the inlet trough. The drive motor is then started to drive the active gear to rotate, which in turn drives the passive gear and the main shaft to rotate. As the medium accumulates in the main shaft, it enters the corresponding support arm. The water pressure generated by the medium pushes open the check plate, thereby releasing the medium into the wastewater. Because the distribution of the support arms can achieve the effect of simultaneous release of different water levels, the rotation of the main shaft and the support arms can improve the mixing effect of the medium and wastewater, thereby improving the efficiency of wastewater treatment. After treatment, the wastewater is sent into the sedimentation tank through the outlet tank for sedimentation, and then the supernatant is discharged from the drain outlet.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-4 This utility model discloses a silicon-containing wastewater treatment device, including a coagulation tank 1, a filter box 4 fixedly connected to one side wall of the coagulation tank 1, a sedimentation tank 7 set on the side of the coagulation tank 1 away from the filter box 4, an inner cavity 9 opened inside the coagulation tank 1, the inner cavity 9 has a cylindrical structure, a main shaft 10 is rotatably connected to the middle of the bottom side wall of the inner cavity 9, a row of support arms 13 is fixedly connected to both side walls of the main shaft 10, the two rows of support arms 13 are staggered, and a discharge port 14 is opened through one side wall of the support arm 13.

[0019] Both the main shaft 10 and the support arm 13 are hollow cylindrical structures. The support arm 13 and the main shaft 10 are internally connected. The discharge port 14 is rotatably connected to the check plate 17 through a torsion spring. The torsion spring is a one-way rotating structure. The top side wall of the coagulation tank 1 is detachably embedded with the drive motor 2. The output end of the drive motor 2 extends into the inner cavity 9 and is detachably connected to the drive gear 12. One side of the drive gear 12 is meshed with the driven gear 11. The driven gear 11 is rotatably connected to the top side wall of the inner cavity 9. The main shaft 10 is inserted and fixedly connected to the middle of the driven gear 11. The top side wall of the coagulation tank 1 away from the drive motor 2 is detachably connected to the storage tank 3 through screws. The side wall of the storage tank 3 near the bottom edge is fixedly connected to the conveying pipe, which is an L-shaped structure. One end of the main shaft 10 passes through the top side wall of the coagulation tank 1 and is sleeved on the end of the conveying pipe away from the storage tank 3.

[0020] The technical effects of this solution are as follows: The medium is fed into the storage tank 3. Liquid medium is added directly, while powdered medium is mixed with water before addition. Then, the medium is fed into the main shaft 10 through the conveying pipe. Starting the drive motor 2 can drive the active gear 12 to rotate. Through the meshing connection, the passive gear 11 and the main shaft 10 rotate synchronously, thereby driving the support arm 13 to rotate, thus stirring the wastewater. The medium accumulates pressure in the main shaft 10 and the support arm 13, which increases the pressure. This allows the check plate 17 to be opened, allowing the medium to be fed into the wastewater. Water pressure can prevent wastewater from entering the support arm 13. The check plate 17 can increase the check-back effect, thus achieving the effect of simultaneous addition and stirring, improving the mixing effect of wastewater and medium. Because it is a layered addition, it can ensure the fullness and uniformity of the mixing between the medium and wastewater. The discharge port 14 is opened on the side wall opposite to the rotation direction of the support arm 13 to ensure smooth feeding.

[0021] A water inlet trough 16 is provided through one side wall at the bottom of the coagulation tank 1. A water outlet tank 15 is fixedly connected to the side wall of the coagulation tank 1 away from the water inlet trough 16. The coagulation tank 1 is connected to one side wall of the sedimentation tank 7 through the water outlet tank 15. A drain outlet 8 is provided through one side of the sedimentation tank 7 away from the coagulation tank 1 and near the top edge. Three pairs of side grooves 18 are provided on the opposite side walls of the filter tank 4. Filter plates 5 are inserted into the side grooves 18. The filter plates 5 are divided into three pieces, and the filter holes on the three filter plates 5 gradually decrease in size. A cover plate 6 is detachably connected to the top of the filter plates 5 by a snap fastener. An outlet is provided through the side wall of the filter tank 4 opposite to the water inlet trough 16. The filter tank 4 and the coagulation tank 1 are connected to the water inlet trough 16 through the outlet.

[0022] The technical benefits of this solution are as follows: the cover plate 6 and the filter plate 5 are designed with a snap-fit ​​connection, which facilitates the disassembly and maintenance of the filter plate 5 in the future. The side groove 18 makes it easier to assemble and disassemble the filter plate 5 and the filter box 4. A gate valve is connected in the water inlet trough 16, which can be opened and closed as needed. Similarly, a valve is connected to the water outlet tank 15, which can send the mixed wastewater into the sedimentation tank 7 as needed. The wastewater settles in the sedimentation tank 7, and the supernatant will be discharged from the drain outlet 8.

[0023] Specifically, in use, wastewater is first sent into the filter box 4 through a pipe connected to the filter box 4. The wastewater is filtered by the filter plate 5 in the filter box 4. Then, the gate valve in the inlet tank 16 is opened to send the filtered wastewater into the inner cavity 9. The coagulation medium is sent into the main shaft 10 and the support arm 13 in advance through the conveying pipe. The drive motor 2 is started to drive the drive gear 12 to rotate. With the help of the meshing connection, the driven gear 11 and the main shaft 10 rotate synchronously. Under the action of the medium pressure, the check plate 17 is pushed open, thereby releasing the medium into the wastewater. Thanks to the distribution of the support arm 13, it can ensure layered release. With the rotation of the support arm 13, the mixing efficiency of wastewater and medium can be improved. The mixed wastewater is sent into the sedimentation tank 7 through the outlet tank 15 for sedimentation. Then, the next batch is mixed to achieve the effect of continuous treatment.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
