Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency, low-failure sludge discharge device. Background Technology

[0002] In domestic sewage treatment, stabilization tanks are used to further settle the sewage after the sludge has settled in the clarifier. At this time, the sludge in the stabilization tank is in a thin mud state and settles at the bottom of the tank. In the treatment process, this thin mud needs to be pumped out and discharged back to the clarifier for further treatment. In the existing technology, one or more sludge suction pumps are usually installed at the bottom of the stabilization tank. However, this method has a slow pumping speed, and if the sludge flows too widely, it will cause settling difficulties. Alternatively, as disclosed in Chinese Patent Publication No. CN218686627U, "A Sludge Discharge Device for a Wastewater Treatment Stabilization Tank"; this utility model discloses a sludge discharge device for a wastewater treatment stabilization tank, including a stainless steel float base and a moving device; the moving device is mainly composed of a first drum assembly and a second drum assembly respectively set on both banks of the stabilization tank, with a first steel wire rope wound on the first drum assembly and the second drum assembly; both ends of the top of the stainless steel float base are provided with suspension guide wheels, which are connected to the first steel wire rope for suspension; guide rods are provided on both the front and rear sides of the stainless steel float base, and the guide rods are provided with a sludge pump height adjustment component for installing the sludge pump and adjusting the height of the sludge pump. This utility model uses a movable stainless steel float base set on the water surface of the stabilization tank to install the sludge pump, and the height of the sludge pump can be adjusted; this makes the sludge pump draw up the sludge faster and avoids the problem of difficult sedimentation caused by the sludge flowing over a large range.

[0003] However, the sludge discharge device in the aforementioned utility model patent only has one sludge suction pump for sludge discharge. This method results in an excessively long sludge discharge pipe, which is prone to tangling during operation and causing malfunctions. Furthermore, the sludge discharge efficiency is low. Utility Model Content

[0004] To address the problem of slow sludge extraction and discharge speed in the existing wastewater treatment ponds, this invention provides a highly efficient and low-failure sludge discharge device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency, low-failure sludge discharge device includes a wastewater treatment tank, a stainless steel float base, and a mobile device. The mobile device is mainly composed of a first drum assembly and a second drum assembly respectively located on both banks of the wastewater treatment tank, with steel wire ropes wound on the first and second drum assemblies. Suspension guide wheels are provided at both ends of the top of the stainless steel float base, and the suspension guide wheels are connected to the first steel wire ropes for suspension. Guide rods are provided on both the front and rear sides of the stainless steel float base, and sludge pump height adjustment components are provided on the guide rods for installing and adjusting the height of the sludge pump. A sludge suction pipe is provided at the inlet end of the sludge pump for sucking up thin sludge from the stabilization tank, and a discharge hose is provided at the outlet end of the sludge pump for discharging thin sludge without affecting the movement of the stainless steel float base. Two stainless steel float bases are installed on the mobile device, spaced half the length of the wastewater treatment tank.

[0007] Preferably, the stainless steel float base is provided with a fixing seat on both the front and rear sides, and a nut is provided on one side of the fixing seat. Several fixing holes are evenly distributed on the guide rod along the vertical direction, and the guide rod is fixed by bolt assembly through the fixing holes and screwed to the nut for adjusting the height adjustment stroke of the sludge pump.

[0008] Preferably, the bottom of the guide rod is provided with an anti-fall plate to prevent the mud pump from falling and causing damage in case of a malfunction in the height adjustment component of the mud pump.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model sets two stainless steel float bases at a distance of half the length of the sewage treatment tank on the mobile device. Each stainless steel float base is equipped with a sludge suction pump to suck up thin sludge, further accelerating the sludge discharge speed. Furthermore, compared to using a single sludge suction pump, the discharge hose is shorter and less prone to tangling, and the travel distance of the mobile device is shortened, reducing the device's failure rate. Simultaneously, the fixed guide rod of the sludge suction pump is height-adjustable, allowing for height adjustment and stroke adjustment, thus improving practicality. Attached Figure Description

Detailed Implementation

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figures 1 to 4 As shown, this utility model embodiment includes a sewage treatment tank, a stainless steel float base, and a moving device. The moving device is mainly composed of a first drum assembly and a second drum assembly respectively set on both banks of the sewage treatment tank, with steel wire ropes wound on the first drum assembly and the second drum assembly. Suspension guide wheels are provided at both ends of the top of the stainless steel float base, and the suspension guide wheels are connected to the first steel wire rope for suspension. Guide rods are provided on both the front and rear sides of the stainless steel float base, and sludge pump height adjustment components are provided on the guide rods for installing and adjusting the height of the sludge pump. A sludge suction pipe is provided at the inlet end of the sludge pump for sucking up the sludge in the stabilization tank, and a discharge hose is provided at the outlet end of the sludge pump for discharging the sludge without affecting the movement of the stainless steel float base. There are two stainless steel float bases, which are installed on the moving device with a gap of half the length of the sewage treatment tank.

[0018] The stainless steel float base 4 can move within the sewage treatment tank 1 under the action of the moving device 3. For example, the first drum assembly 301 and the second drum assembly 302 rotate clockwise, causing the first wire rope 303 to form a clockwise rotating conveyor belt. Since the stainless steel float base 4 is suspended from the first wire rope 303 by the suspension guide wheel 2, it can move to the right on the water surface of the sewage treatment tank 1. Conversely, the first drum assembly 301 and the second drum assembly 302 rotate counterclockwise, causing the stainless steel float base 4 to move to the left on the water surface of the sewage treatment tank 1. This drives the sludge pump 6 to move left and right to suck up the sludge settled at the bottom of the sewage treatment tank 1, avoiding difficulties in sludge extraction and increasing the sludge discharge speed. There are two stainless steel float bases 4, which are installed on the moving device 3 with a spacing of half the length of the sewage treatment tank 1. In this way, the two sludge pumps 7 perform sludge extraction operations simultaneously, further accelerating the sludge discharge speed. Moreover, compared with setting up a single sludge pump 7, the discharge hose 9 is shorter and less prone to tangling, reducing the failure rate of the device.

[0019] Preferably, the stainless steel float base 4 is provided with a fixing seat 10 on both the front and rear sides, and a nut 12 is provided on one side of the fixing seat 10. Several fixing holes 502 are evenly distributed on the guide rod 5 along the vertical direction, and the guide rod 5 is fixed by bolt assembly 11 through the fixing holes 502 and screwed to the nut 12 for adjusting the height adjustment stroke of the mud suction pump 7.

[0020] Preferably, the bottom of the guide rod 5 is provided with an anti-fall plate 501 to prevent the mud pump 7 from falling and being damaged when the height adjustment component 6 of the mud pump malfunctions.

[0021] 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.
