Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, and in particular to an industrial wastewater deep treatment device. Background Technology

[0002] Flocculation sedimentation is a common method for advanced wastewater treatment. After adding a coagulant to the water, the colloidal and dispersed particles of suspended solids form flocs under the interaction of molecular forces. During sedimentation, these flocs collide and aggregate, continuously increasing in size and mass, and their settling velocity. Flocculation sedimentation occurs in surface water after adding coagulants, in domestic sewage, and in activated sludge. Current technologies typically involve installing a sludge scraper bridge on the sedimentation tank. The movement of the scraper bridge is controlled to remove the settled sludge, while a water pump is used to pump the sludge out.

[0003] According to a Chinese patent document (authorization announcement number: CN215692382U), an industrial wastewater deep treatment device includes a sedimentation tank. A slide rail is fixedly installed on the top edge of the sedimentation tank. A sludge scraper bridge is installed on the top of the sedimentation tank. A support leg is fixedly connected to the bottom of the sludge scraper bridge. A first pulley is fixedly connected to the bottom of the support leg and is slidably connected to the slide rail. A sludge suction pipe is fixedly connected to the bottom of the sludge scraper bridge. Multiple branch pipes are fixedly connected to the bottom of the sludge suction pipe. The bottom end of the branch pipe extends into the interior of the sedimentation tank and is equipped with a scraper. A water pump is installed at one end of the sludge suction pipe, and the input end of the water pump is fixedly connected to the sludge suction pipe. The beneficial effect of this industrial wastewater deep treatment device is that by setting multiple steel frames on the side of the sludge scraper bridge and connecting rainproof cloth between the multiple steel frames, the rainproof cloth can be unfolded by moving the steel frames along the slide rail, thereby achieving rain protection and preventing sewage overflow from the sedimentation tank during rainy days. At the same time, it is easier to install and has a lower cost than a rain shelter.

[0004] However, the above solution still has the following problems when used:

[0005] The mud scraper bridge relies on the sliding connection between pulleys and rails. It is not equipped with an automated drive structure and requires manual assistance or an additional power source. It is inconvenient to operate and has low efficiency. Furthermore, the unfolding of the rainproof cloth and the movement of the mud scraper bridge are independent of each other and require additional operation. They cannot achieve synchronous linkage, which increases the cost of use and management difficulty.

[0006] Therefore, we propose an advanced industrial wastewater treatment device. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies. The mud scraper bridge relies on the sliding connection between pulleys and slide rails, lacks an automated drive structure, requires manual assistance or an additional power source, is inconvenient to operate and has low efficiency. Furthermore, the unfolding of the rainproof cloth and the movement of the mud scraper bridge are independent of each other, requiring additional operation and failing to achieve synchronous linkage, which increases the cost of use and management difficulty.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An industrial wastewater deep treatment device includes a sedimentation tank. A drive structure is provided on both side walls of the top of the sedimentation tank. A sludge removal component is provided at the connection of the drive structure. A rainproof component is also provided at the connection of the sludge removal component. The sludge removal component and the drive structure are detachable. The drive structure can drive the sludge removal component to perform automatic cleaning and can drive the rainproof component to move synchronously while cleaning. A discharge pipe is provided on the front of the sedimentation tank.

[0010] As a preferred embodiment of this utility model, the driving structure includes two mounting seats, each of which has a mounting groove inside. Each of the two mounting grooves has a lead screw and a first linear optical axis inside. Each of the lead screw and the first linear optical axis has a connecting slider. Each of the two connecting sliders has a first connecting flange on its inner sidewall. A drive motor is provided on the input end of the lead screw.

[0011] As a preferred embodiment of this utility model, the sludge removal assembly includes a movable base, a connecting pipe is installed on the top of the movable base, a sludge removal plate is installed on the bottom of the movable base, a plurality of sludge suction ports are opened on the outer surface of the sludge removal plate, and connecting parts are provided on both side walls of the movable base, and a second connecting flange is provided on the outer side wall of each of the two connecting parts.

[0012] As a preferred embodiment of this utility model, the rainproof component includes two fixing plates, two second linear optical axes are provided between the two fixing plates, a sliding seat is also installed between the two second linear optical axes, two connecting blocks are provided at the connection of the sliding seat, and a rainproof cloth is provided between the sliding seat and one of the fixing plates.

[0013] In a preferred embodiment of this utility model, the connecting slider is connected to the second connecting flange of the connecting member through the first connecting flange, and is connected and disassembled by bolts.

[0014] As a preferred embodiment of this utility model, the drive motor drives the lead screw to rotate, thereby moving the connecting slider. Both connecting sliders are connected to the desludge assembly through two first connecting flanges, thereby moving the desludge assembly to remove mud.

[0015] As a preferred embodiment of this utility model, the connecting pipe is connected to several suction ports through several pipes installed in the movable seat and the mud removal plate, and the other end of the connecting pipe is connected to the pump body, thereby performing mud pumping operation through the several suction ports.

[0016] As a preferred embodiment of this utility model, the sliding seat is slidably connected to the two second linear optical axes, and the sliding seat is connected to the two connecting members through two connecting blocks, thereby driving the sliding seat to move and unfold the rainproof cloth.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the drive structure consisting of a lead screw, a first linear optical shaft, and a drive motor can automatically drive the sludge removal component to move at the top of the sedimentation tank without manual assistance or additional complex power sources. Compared with the existing sludge scraper bridge that relies on pulleys and rails and requires manual operation, this invention significantly reduces labor costs and improves the automation level and work efficiency of sludge cleaning.

[0019] The sludge removal component and the rainproof component are rigidly linked by a connecting block. While the drive structure moves the sludge removal component to clean the sludge, the sliding seat of the rainproof component can simultaneously move the rainproof cloth to unfold or retract. The rainproof function can be achieved without additional operation. This design effectively avoids the drawbacks of the rainproof cloth and the sludge scraper bridge moving independently and requiring separate operation in the existing technology, reducing operation steps and management costs, while preventing rainwater from mixing into the sedimentation tank and affecting the treatment effect.

[0029] Example

[0030] like Figure 1-4As shown, this utility model provides a technical solution: an industrial wastewater deep treatment device, including a sedimentation tank 1, a driving structure is provided on the two side walls of the top of the sedimentation tank 1, a sludge removal component is provided at the connection of the driving structure, and a rainproof component is also provided at the connection of the sludge removal component. The sludge removal component and the driving structure are detachable, and the driving structure can drive the sludge removal component to perform automatic cleaning, and can drive the rainproof component to move synchronously while cleaning. A discharge pipe 5 is provided on the front of the sedimentation tank 1.

[0031] The drive structure serves as the core power source, driving the sludge removal component to move along the top of the sedimentation tank 1 via mechanical transmission. The linkage design between the sludge removal component and the rainproof component allows the rainproof cloth 45 to be deployed or retracted simultaneously during sludge removal operations, preventing rainwater from interfering with the wastewater treatment process. The discharge pipe 5 is used to discharge the treated wastewater from the sedimentation tank 1. All components work together to achieve deep treatment of industrial wastewater.

[0032] The drive structure includes two mounting bases 21, each with a mounting groove 22 inside. The two mounting grooves 22 are respectively provided with a lead screw 23 and a first linear optical axis 24. Both the lead screw 23 and the first linear optical axis 24 are provided with connecting sliders 25. The inner sidewalls of the two connecting sliders 25 are provided with first connecting flanges 26. The input end of the lead screw 23 is provided with a drive motor 27.

[0033] After the drive motor 27 is powered on, the output shaft drives the lead screw 23 to rotate. Since the lead screw 23 and the connecting slider 25 are connected by a thread, according to the principle of screw transmission, the rotational motion of the lead screw 23 is converted into the linear motion of the connecting slider 25 along the axis of the lead screw 23. The first linear optical axis 24 provides guidance and support for the connecting slider 25, restricting it from rotating or deviating during movement, ensuring that the connecting slider 25 can only move stably in a straight line. The two connecting sliders 25 are connected to the sludge removal assembly through the first connecting flange 26, thereby driving the sludge removal assembly to perform precise linear reciprocating motion at the top of the sedimentation tank 1, realizing automated sludge removal operation.

[0034] The sludge removal assembly includes a movable base 31, a connecting pipe 32 is installed on the top of the movable base 31, a sludge removal plate 33 is installed on the bottom of the movable base 31, a number of sludge suction ports 34 are opened on the outer surface of the sludge removal plate 33, and connectors 35 are provided on both side walls of the movable base 31, and a second connecting flange 36 is provided on the outer side wall of each of the two connectors 35.

[0035] After the pump starts, a negative pressure environment is formed in the pipes in the connecting pipe 32, the movable seat 31 and the sludge removal plate 33. Since the sludge suction port 34 is connected to these pipes, the sludge accumulated at the top of the sedimentation tank 1 is sucked into the pipes through the sludge suction port 34 under atmospheric pressure, and then transported to the subsequent treatment equipment through the connecting pipe 32. As the drive structure drives the movable seat 31 to move at the top of the sedimentation tank 1, the multiple sludge suction ports 34 on the sludge removal plate 33 can cover a larger area, continuously extracting and collecting sludge, and achieving efficient cleaning of the sludge in the sedimentation tank 1.

[0036] The rainproof component includes two fixed plates 41, two second linear optical axes 42 are provided between the two fixed plates 41, a sliding seat 43 is also installed between the two second linear optical axes 42, two connecting blocks 44 are provided at the connection of the sliding seat 43, and a rainproof cloth 45 is provided between the sliding seat 43 and one of the fixed plates 41.

[0037] When the drive structure moves the sludge removal component, the connecting parts 35 on both sides of the sludge removal component are connected to the sliding seat 43 through the connecting block 44, thereby driving the sliding seat 43 to slide on the second linear optical axis 42. As the sliding seat 43 moves, the rainproof cloth 45 is gradually unfolded or retracted. The second linear optical axis 42 provides a sliding track and support for the sliding seat 43, ensuring that the sliding seat 43 moves smoothly and that the rainproof cloth 45 can be unfolded evenly to effectively block rainwater and prevent rainwater from entering the sedimentation tank 1 and affecting the wastewater treatment effect. At the same time, when rain protection is not required, the rainproof cloth 45 can be retracted without affecting the normal operation and maintenance of the equipment.

[0038] The connecting slider 25 is connected to the second connecting flange 36 of the connector 35 via the first connecting flange 26, and is connected and disassembled by bolts.

[0039] During installation, align the first connecting flange 26 with the second connecting flange 36, pass bolts through the through holes on the flanges and tighten the nuts to make the two flanges fit tightly together, thereby achieving a firm connection between the drive structure and the desliming component. When the desliming component needs maintenance or replacement, simply unscrew the bolts to remove the desliming component from the drive structure. This detachable connection method is simple and quick to operate, facilitating daily maintenance and parts replacement of the equipment, effectively reducing equipment maintenance costs and time. The rainproof component and the desliming component can be connected by flanges in the same way as needed, thus achieving detachability of the three components.

[0040] The drive motor 27 drives the lead screw 23 to rotate, which in turn moves the connecting slider 25. Both connecting sliders 25 are connected to the desludge assembly through two first connecting flanges 26, thereby moving the desludge assembly to remove mud.

[0041] The drive motor 27 starts according to the set program or instructions, and its output torque is transmitted to the lead screw 23. When the lead screw 23 rotates, the connecting slider 25 that cooperates with the lead screw 23 can only move along the axial direction of the lead screw 23 due to the guiding constraint of the first linear optical axis 24. The two connecting sliders 25 move at the same time, and the driving force is transmitted to the connecting part 35 of the sludge removal assembly through the first connecting flange 26, so that the sludge removal assembly moves linearly at the top of the sedimentation tank 1 following the connecting slider 25. During the movement, the sludge suction port 34 of the sludge removal assembly works continuously to extract and remove the sludge in the area along the way, so as to achieve a comprehensive cleaning of the sludge in the sedimentation tank 1.

[0042] The connecting pipe 32 is connected to several suction ports 34 through several pipes installed in the movable seat 31 and the mud removal plate 33. The other end of the connecting pipe 32 is connected to the pump body, and then the mud pumping operation is carried out through the several suction ports 34.

[0043] When the pump is running, it generates suction, creating a negative pressure in the pipes within the connecting pipe 32, the movable seat 31, and the sludge removal plate 33. Since multiple sludge suction ports 34 are connected to these pipes and are located in the sludge layer at the top of the sedimentation tank 1, the sludge is sucked into the suction ports 34 under the action of pressure difference. Then, it passes through the pipes within the sludge removal plate 33 and the pipes within the movable seat 31 in sequence, and is finally transported to the pump body through the connecting pipe 32. The pump body then discharges the sludge to a designated location for further processing. The design of multiple sludge suction ports 34 increases the sludge collection area, improves sludge pumping efficiency, and ensures that the sludge in the sedimentation tank 1 can be removed quickly and effectively.

[0044] The sliding seat 43 is slidably connected to the two second linear optical axes 42. The sliding seat 43 is connected to the two connecting pieces 35 through the two connecting blocks 44, thereby driving the sliding seat 43 to move and unfold the rainproof cloth 45.

[0045] When the drive structure moves the sludge removal component, the connecting parts 35 on both sides of the sludge removal component are connected to the sliding seat 43 through the connecting block 44, which transmits the moving force of the sludge removal component to the sliding seat 43. Since the sliding seat 43 and the second linear optical axis 42 are in a sliding fit relationship, the sliding seat 43 can slide smoothly along the second linear optical axis 42 under the traction of the connecting block 44. As the sliding seat 43 moves, the rainproof cloth 45 between it and the fixed plate 41 is gradually stretched and unfolded to form a rainproof barrier. When the sludge removal component moves in the opposite direction, the sliding seat 43 slides in the opposite direction, and the rainproof cloth 45 gradually retracts, realizing the automatic unfolding and retraction function of the rainproof cloth 45, ensuring that the sedimentation tank 1 can operate normally in rainy weather, while reducing the impact of the rainproof structure on the daily operation of the equipment.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
