Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge removal device for wastewater treatment. Background Technology
[0002] Wastewater treatment refers to the process of treating and purifying domestic sewage, industrial wastewater, agricultural wastewater, etc., to meet discharge standards or water quality requirements for reuse. Sludge removal is to remove sediment and solid particles from the wastewater to prevent them from reducing the treatment effect and affecting the purification efficiency of the wastewater.
[0003] The prior art, disclosed in CN221217229U, describes an anti-clogging sludge discharge device for wastewater treatment. In this device, a pressure frame and a perforated plate come into contact with the wastewater and continuously move downwards. The wastewater flows upwards through the small holes in the perforated plate, while sediment and solid particles in the wastewater are pressed down by the perforated plate. However, the compression of these sediments and solid particles can actually hinder their subsequent discharge through the sludge discharge pipe, or even prevent them from being discharged altogether, thus reducing the sludge discharge efficiency. Therefore, this application proposes a sludge discharge device for wastewater treatment. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a sludge discharge device for sewage treatment.
[0005] An embodiment of this utility model provides a sludge removal device for sewage treatment, comprising:
[0006] Processing box;
[0007] Sludge discharge assembly; the sludge discharge assembly includes a sludge discharge cylinder fixed to the bottom of the processing tank, a first shaft and two second shafts that are rotatably configured and can rotate synchronously are provided through the sludge discharge cylinder, a spiral blade that cooperates with the sludge discharge cylinder is fixed on the first shaft, and multiple stirring rods are fixed on each of the two second shafts, and a sludge discharge pipe opposite to the first shaft is installed through the sludge discharge cylinder.
[0008] Furthermore, the two second shafts are located above the first shaft, and the first shaft and the two second shafts are arranged in a triangle.
[0009] Furthermore, a mounting frame is installed on the sludge discharge cylinder, a motor is installed on the mounting frame, a short rod is fixedly connected to the output end of the motor, and the short rod is fixedly connected to one of the second shafts.
[0010] Furthermore, it also includes a transmission mechanism, which comprises transmission wheels fixed on a first shaft and two second shafts, and the three transmission wheels are connected by a transmission belt.
[0011] Furthermore, the bottom of the sludge discharge cylinder is arranged in an arc shape, and the spiral blade is arranged in accordance with the arc shape.
[0012] Furthermore, a baffle is installed on the sludge discharge pipe.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In this invention, the sludge inside the sludge discharge cylinder is agitated by the stirring rod, which increases the fluidity of the sludge. Due to gravity, the sludge flows to the bottom of the discharge cylinder, thus more effectively discharging all the sludge and avoiding the drawbacks of low discharge efficiency and clogging in the prior art.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0020] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a sludge removal device for sewage treatment, comprising:
[0021] The treatment box 1 has four support legs 2 installed at its bottom. The four support legs 2 are arranged in a rectangular shape to provide stable support for the treatment box 1. The treatment box 1 is equipped with sewage inlet and outlet pipes, which are not shown in the figure.
[0022] Sludge discharge assembly; The sludge discharge assembly includes a sludge discharge cylinder 4 fixed to the bottom of the treatment tank 1. A first shaft 11 and two second shafts 9 are rotatably mounted on the sludge discharge cylinder 4 and can rotate synchronously. The second shafts 9 are located above the first shaft 11, and the first shaft 11 and the two second shafts 9 are arranged in a triangle.
[0023] A mounting frame 5 is installed on the mud discharge cylinder 4, and a motor 6 is installed on the mounting frame 5. A short rod 13 is fixedly connected to the output end of the motor 6. The short rod 13 is fixedly connected to one of the second shafts 9. The system also includes a transmission mechanism, which includes transmission wheels 8 fixed on the first shaft 11 and the two second shafts 9. The three transmission wheels 8 are connected by a transmission belt 7. Through the cooperation of the transmission wheels 8 and the transmission belt 7, the first shaft 11 and the second shafts 9 rotate synchronously.
[0024] A spiral blade 12 that mates with the sludge discharge cylinder 4 is fixed on the first shaft 11. The bottom of the sludge discharge cylinder 4 is arc-shaped, and the spiral blade 12 is arranged to mate with the arc shape. Multiple stirring rods 10 are fixed on each of the two second shafts 9. A sludge discharge pipe 3 that is opposite to the first shaft 11 is installed through the sludge discharge cylinder 4. A baffle is installed on the sludge discharge pipe 3. When the baffle is opened, the sludge can be discharged through the sludge discharge pipe 13.
[0025] When sludge needs to be discharged, the staff starts the motor 6. The motor 6 drives the short rod 13 and the second shaft 9 to rotate. Under the transmission of the transmission belt 7 and the transmission wheel 8, the first shaft 11 and the two second shafts 9 rotate. The rotation of the second shafts 9 drives the stirring rod 10 to rotate, which can stir and break up the sludge and facilitate the flow of the sludge. The rotation of the first shaft 11 drives the spiral blade 12 to rotate, which, together with the sludge discharge cylinder 4, can discharge the sludge through the sludge discharge pipe 3.
[0026] like Figure 3 As shown, since the sludge discharge cylinder 4 is V-shaped, the sludge on the upper side is agitated by the stirring rod 10, which increases the fluidity of the sludge. Due to gravity, it flows to the bottom of the sludge discharge cylinder 4, thus more effectively discharging all the sludge and avoiding the disadvantages of low discharge efficiency and clogging in the existing technology.
[0027] 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. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
