Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an anaerobic treatment tank for industrial wastewater. Background Technology
[0002] Anaerobic digesters are facilities that treat high-concentration organic wastewater and sludge using the principle of anaerobic fermentation. Their core feature is the absence of a biogas collection device, offering advantages such as simple structure, no external power required, and convenient operation. These facilities are widely used in wastewater treatment engineering. Typical examples include industrial park projects employing a combined process of 'hydrolysis acidification tank-carrousel oxidation ditch', and two-phase anaerobic process systems achieving CODcr removal rates exceeding 85% in pulp wastewater treatment.
[0003] For example, publication number CN222647771U, publication date March 21, 2025, titled "An Anaerobic Wastewater Treatment Tank," includes a frame placed on four sides of the anaerobic tank. The frame is equipped with an automatic start-stop mechanism, which includes a reduction gear assembly and a transmission assembly. The reduction gear assembly includes a first motor fixedly connected to the frame, with a drive rod fixedly connected to the output shaft of the first motor and a power disk rotatably connected thereto. The drive rod drives the power disk to rotate intermittently via a connecting piece. The transmission assembly includes a horizontal rod slidably connected to the frame, with a moving rod fixedly connected to the horizontal rod. The power disk drives the horizontal rod to move via the moving rod. A reciprocating mechanism is also provided between the frame and the horizontal rod, and a stirring mechanism is connected to the reciprocating mechanism. This utility model can automatically complete the stirring work of the anaerobic tank without manual control, improving wastewater treatment efficiency, and extending the motor's service life by eliminating the need for frequent start-stop operations.
[0004] In existing technologies, such as those containing the aforementioned patents, scum is generated during the operation of anaerobic tanks. If the scum is not removed in time, it will affect gas release and the exchange of wastewater at the surface. Excessive accumulation of scum will reduce the effective volume and affect the treatment effect. Utility Model Content
[0005] The purpose of this invention is to provide an anaerobic treatment tank for industrial wastewater to address the shortcomings of the existing technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anaerobic treatment tank for industrial wastewater, comprising:
[0007] Pool body;
[0008] Two cleaning plates are fixedly connected to both sides of the pool body;
[0009] The slag cleaning mechanism includes a crossbar slidably connected to the pool body, a fixed plate fixedly connected to the crossbar, an abutment rod fixedly connected to the fixed plate, an abutment groove opened on the pool body, the abutment rod slidably connected in the abutment groove, an installation frame fixedly connected to the crossbar, and a filter plate detachably connected to the installation frame through a connecting mechanism, with each side of the filter plate corresponding to and slidingly abutting against two cleaning plates.
[0010] Furthermore, the abutment groove includes a filter section, both sections of which are connected to a flipping section, and both flipping sections are connected to a cleaning section.
[0011] Furthermore, both ends of the crossbar are rotatably connected to sliders, and the pool body is provided with grooves for the two sliders to slide.
[0012] Furthermore, a screw is rotatably connected to the pool body, and the screw is screwed to the slider.
[0013] Furthermore, there is a certain distance between the cleaning plate and the two side walls of the pool.
[0014] Furthermore, the connecting mechanism includes a pin that is slidably connected to the mounting frame, the pin being inserted into the filter plate, and an elastic element being provided between the pin and the mounting frame.
[0015] Furthermore, the elastic element is a tension spring.
[0016] Compared with the prior art, the industrial wastewater anaerobic treatment tank provided by this utility model uses a crossbar that moves laterally within the tank to drive the filter plate to move synchronously. At the same time, the abutment rod slides within the abutment groove. During the movement, the filter plate cleans the scum on the water surface within the tank. As the movement continues, the filter plate first rotates from a vertical state to a horizontal state, and then slides and abuts against one of the cleaning plates. Through the contact between the two, the scum attached to the filter plate is cleaned off and removed, preventing the accumulation of scum. Attached Figure Description

Detailed Implementation
[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] Please see Figure 1-5 The present invention provides an anaerobic treatment tank for industrial wastewater, comprising: a tank body 1, the bottom of which may be located below ground level; two cleaning plates 2, which are respectively fixedly connected to both sides of the tank body 1; preferably, a brush is fixedly connected to the top surface of the cleaning plate 2, and the brush abuts against the filter plate 37. Through the abutting cooperation between the two, the scum attached to the filter plate 37 can be cleaned off to a certain extent.
[0026] The slag cleaning mechanism 3 includes a crossbar 31 slidably connected to the pool body 1, a fixing plate 34 fixedly connected to the crossbar 31, an abutment rod 35 fixedly connected to the fixing plate 34, an abutment groove opened on the pool body 1, the abutment rod 35 slidably connected in the abutment groove, an installation frame 36 fixedly connected to the crossbar 31, and a filter plate 37 detachably connected to the installation frame 36 through a connecting mechanism 4, with the two sides of the filter plate 37 correspondingly slidingly abutting against the two cleaning plates 2.
[0027] It must be noted that the abutment rod 35 is eccentrically positioned on the fixing plate 34.
[0028] Specifically, the crossbar 31 is slidably connected to the pool body 1 via the slider 32; the specific connection method is as follows: both ends of the crossbar 31 are rotatably connected to the slider 32, and the pool body 1 is provided with a sliding groove 11 for the two sliders 32 to slide.
[0029] More specifically, a screw 33 is rotatably connected to the pool body 1, and the screw 33 is screwed to the slider 32; it is understood that in this embodiment, at least one of the sliders 32 is screwed to the screw 33; this embodiment also includes a drive source (not shown in the figure) for driving the screw 33, the drive source is a motor, and the output end of the motor is coaxially fixedly connected to the screw 33.
[0030] Specifically, the abutment groove includes a filter section 12, both sections of the filter section 12 are connected to a flipping section 13, and both flipping sections 13 are connected to a cleaning section 14; wherein the filter section 12 and the cleaning section 14 are arranged in parallel, and the flipping section 13 is arranged obliquely upward.
[0031] Preferably, there is a certain distance between the cleaning plate 2 and the two side walls of the pool body 1; it is understood that this distance allows the fixing plate 34 and the abutment rod 35 to pass through smoothly, thereby avoiding interference with the cleaning plate 2.
[0032] Preferably, the connecting mechanism 4 includes a pin 41 that is slidably connected to the mounting frame 36, the pin 41 being inserted into the filter plate 37, and an elastic element 42 being provided between the pin 41 and the mounting frame 36; specifically, the elastic element 42 is a tension spring.
[0033] Working principle: When in use, the screw 33 rotates, and through its screw connection with the slider 32, it drives the crossbar 31, the mounting frame 36, and the filter plate 37 to move laterally in the first direction, thereby cleaning the scum on the water surface in the pool 1. During this process, the abutting rod 35 always slides within the filter section 12 of the abutting groove.
[0034] As the crossbar 31 continues to move, after the abutment rod 35 slides from the filter section 12 into the flipping section 13, it will drive the abutment rod 35 to rotate about the axis of the fixed plate 34, thereby driving the crossbar 31, the mounting frame 36, and the filter plate 37 to rotate 90 degrees synchronously, so that the filter plate 37, which was originally in a vertical state, becomes horizontal, and the side of the filter plate 37 that is in the same direction as the first direction before flipping faces down.
[0035] As the crossbar 31 continues to move, the abutment rod 35 slides from the flipping section 13 into the cleaning section 14, causing the horizontal filter plate 37 to move closer to the cleaning plate 2 and slide into contact with the cleaning plate 2. Through the contact between the two, the scum attached to the filter plate 37 is cleaned.
[0036] Understandably, the process of the filter plate 37 moving laterally in the second direction is the same. First, the scum will be cleaned, then the other side of the filter plate 37 will face down and come into contact with another cleaning plate 2, and then the scum on the other side of the filter plate 37 will be cleaned.
[0037] When the filter plate 37 needs to be replaced after a long period of use, it can be quickly replaced through the connecting mechanism 4.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
