Description

Technical Field

[0001] The utility model relates to the technical field of spiral screw sludge dewatering machines for sewage treatment, in particular to a detachable spiral screw sludge press. Background Art

[0002] The spiral screw sludge press is a spiral screw type sludge dewatering machine used for dewatering sludge in sewage treatment. Since the sludge is still in a liquid flowing state and has a large volume after concentration or digestion, it cannot be transported and disposed of. In order to further reduce the water content and make the water content of the sludge as low as possible, a spiral screw sludge press must be used to dehydrate the sludge again to reduce the sludge volume and facilitate transportation.

[0003] The currently used spiral screw sludge press is provided with a frame on the machine base, and a main shaft with spiral screw blades is rotatably arranged inside the frame. However, since the box body of the frame is usually a hollow structure, during the process of the main shaft driving the spiral screw blades to rotate for sludge dewatering, the noise is relatively large. Prolonged exposure to such noise will cause damage to the physical health of the staff. In addition, the frame for installing the main body of the spiral screw machine is fixed and spliced with bolts, making it difficult to disassemble and operate when cleaning and maintaining the main body of the spiral screw machine inside the frame. Moreover, the sewage discharged after the spiral screw sludge press dewatering the sludge is directly discharged, still posing a risk of environmental pollution. Content of the Utility Model

[0004] In view of the above existing technical problems, the utility model provides a detachable spiral screw sludge press. The frame is composed of an upper cover and a bottom plate in a "concave" structure. The upper cover and the bottom plate are connected in a limited way through multiple groups of connecting components installed on both sides of the bottom plate. The installation and disassembly operation of the frame is convenient. In addition, a filter box is installed below the bottom plate of the frame, and the filter components in the filter box filter and purify the discharged sewage before discharging, reducing environmental pollution problems.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0024] Embodiment 1

[0025] As shown in the figure, a pretreatment stirring assembly 101 is installed at one end of the machine base 1. The pretreatment stirring assembly 101 is connected to the main body 102 of the spiral press through a connecting pipe 103. The main body 102 of the spiral press is installed on the frame. Among them, the pretreatment stirring assembly 101 is a mechanism composed of a stirring tank, a stirring motor, and a stirring rod, which is used for the process of stirring sewage and flocculant to cause flocculation and precipitation of sewage. The main body 102 of the spiral press is an existing device, so it will not be described in detail in this application.

[0026] The frame for installing the main body 102 of the spiral press is fixedly installed on the machine base 1. The frame is composed of a bottom plate 21 and an upper cover 22. The bottom plate 21 is installed on the machine base 1. The bottom plate 21 is connected to the upper cover 22 through multiple groups of connecting components. Pulling rings 221 are arranged on both sides of the upper cover 22, which is convenient for operation when disassembling to remove the upper cover 22. For example, Figure 3 and 4 In the connecting component, the mounting plate 31 is fixedly installed on the side of the bottom plate 21 by screws. A fixing ring 32 is fixedly connected to the mounting plate 31. The locking column 33 passes through the through holes on the two fixing rings 32, and the front end of the locking column 33 is inserted into the limiting hole 222 provided on the upper cover 22. An operation plate 34 is arranged on the locking column 33 for facilitating the operation of the locking column 33, and a limiting block 35 for setting the position of the operation plate 34 is arranged on the mounting plate 31.

[0027] Among them, the upper cover 22 is set in a "concave" structure, and a sound insulation layer 23 is arranged inside the upper cover 22. The sound insulation layer 23 is mainly composed of sound-absorbing cotton. When manufacturing the upper cover 22, the sound-absorbing cotton is filled inside the upper cover 22 to form the sound insulation layer 23.

[0028] A mounting grid plate 211 is arranged on the bottom plate 21, and a filtering box 4 is arranged below the bottom plate 21. A filtering component is arranged inside the filtering box 4. The filtering component is composed of a filter screen 51 and an activated carbon adsorption layer 52. The filter screen 51 is located above the activated carbon adsorption layer 52, and a drain pipe 41 is arranged on one side of the bottom of the filtering box 4.

[0029] Embodiment 2

[0030] When it is necessary to maintain or clean the main body 102 of the spiral press inside the frame, the staff operates the operation plate 34 in the connecting component, rotates the operation plate 34 from the vertical direction to the horizontal direction, so that it is not limited by the limiting block 35, and then moves the locking column 33 by moving the operation plate 34 backward, so that the front end of the locking column 33 moves out of the limiting hole 222 of the upper cover 22. All four groups of connecting components are operated in this way. Subsequently, the upper cover 22 is lifted through the pulling ring 221 on the upper cover 22 to separate the upper cover 22 from the bottom plate 21, and the operation is convenient.

[0031] After the maintenance is completed or the cleaning is finished, similarly, first place the upper cover 22 on the bottom plate 21, and then move the locking column 33 by operating the operating plate 34 in the connecting component so that the front end of the locking column 33 is inserted into the limiting hole 222 provided on the upper cover 22. Moreover, the position of the operating plate 34 is limited by the limiting block 35 provided on the mounting plate 31, that is, the assembly of the upper cover 22 and the bottom plate 21 is completed.

[0032] During the sludge dewatering process, the sewage after passing through the pretreatment stirring component 101 is transported to the spiral press main body 102 through the connecting pipe 103. The squeezed water flows into the filter box 4 from the grid plate 211 on the bottom plate 21. The dewatered mud blocks are discharged from the sludge discharge port of the spiral press main body 102. The sewage dewatered from the sludge flows into the filter box 4 from the grid plate 211 on the bottom plate 21. After passing through the filtering component in the filter box 4, the sewage is filtered and purified by the filter net 51 and the activated carbon adsorption layer 52 before being discharged, reducing the pollution to the environment.
