A type of anti-accumulation screw press sludge dewatering machine

Abstract

This utility model relates to the technical field of sludge dewatering equipment and discloses an anti-accumulation screw press sludge dewatering machine, including a dewatering machine body. A fixed plate is fixedly connected to the discharge port of the dewatering machine body, and a frame is fixedly connected to the bottom of the fixed plate. Multiple fixed inclined plates are fixedly connected to the inner side of the frame, and a movable inclined plate is closely attached between adjacent fixed inclined plates. A sliding component is fixedly connected to the side of the movable inclined plate away from the fixed inclined plate. In this anti-accumulation screw press sludge dewatering machine, when the sludge cake flows out of the dewatering machine body, it falls onto the fixed inclined plate of the frame. Guided by the fixed and movable inclined plates, the sludge cake eventually falls into the designated position. Since both the fixed and movable inclined plates are arranged at an angle and do not form a complete plane, the contact area between the sludge cake and them is greatly reduced, thereby reducing the possibility of the sludge cake adhering to the fixed or movable inclined plates and effectively reducing the occurrence of sludge cake accumulation.

Description

Technical Field

[0001] This utility model relates to the technical field of sludge dewatering equipment, specifically a screw press sludge dewatering machine with anti-accumulation function. Background Technology

[0002] A screw press sludge dewatering machine is a specialized mechanical device that uses the relative motion between a screw shaft and a screw press to achieve sludge thickening and dewatering. The screw press, as its core component, is precisely machined and meticulously assembled to form several regular filter slots. During operation, the sludge flows slowly through these filter slots under the continuous push of the screw shaft. During this process, the water contained in the sludge is squeezed out through the filter slots, thus achieving sludge-water separation.

[0003] Currently, during operation, the sludge cake discharged from the screw press sludge dewatering machine often adheres to the guide plate due to its own viscosity or surface tension, leading to accumulation and blockage. This problem forces operators to perform frequent manual cleaning, severely impacting the continuous operating efficiency of the equipment. The traditional solution is to replace the anti-sticking material, such as a Teflon coating; however, this approach is costly and the material has poor durability, resulting in a deficiency in preventing sludge cake accumulation in the screw press sludge dewatering machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-accumulation screw press sludge dewatering machine, which makes it difficult for the sludge cake in the main body of the dewatering machine to accumulate on the fixed plate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dewatering machine for preventing the accumulation of sludge by stacked screw presses, comprising a dewatering machine body, a fixed plate fixedly connected to the discharge port of the dewatering machine body, a frame fixedly connected to the bottom of the fixed plate, a plurality of fixed inclined plates fixedly connected to the inner side of the frame, a movable inclined plate closely attached between adjacent fixed inclined plates, and a sliding component fixedly connected to the side of the movable inclined plate away from the fixed inclined plate.

[0006] Furthermore, the sliding assembly includes a connecting plate, a side plate, and a slider. The connecting plate is fixedly connected to the side of the movable inclined plate away from the fixed inclined plate, and the side plates are fixedly connected to both sides of the connecting plate. A sliding groove is provided at the end of the side plate away from the connecting plate, and the slider is slidably connected inside the sliding groove. The slider is fixedly connected to the outer wall of the frame.

[0007] Furthermore, the end of the slider is trapezoidal.

[0008] Furthermore, a sliding rod is slidably connected to the middle position of the slider, and the two ends of the sliding rod are respectively fixed to the two ends of the sliding groove.

[0009] Furthermore, a fixing bolt is threaded onto the side of the slider away from the frame, and the end of the fixing bolt abuts against the slider rod.

[0010] Furthermore, the end of the fixing bolt away from the slider is hexagonal.

[0011] Furthermore, an elastic element is fitted at one end of the slide rod near the connecting plate. One end of the elastic element is fixedly connected to the end of the slide groove, and the other end of the elastic element is fixedly connected to the slider.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this type of anti-accumulation screw press sludge dewatering machine, when the sludge cake flows out of the main body of the dewatering machine, it will fall onto the fixed inclined plate of the frame. Guided by the fixed and movable inclined plates, the sludge cake will eventually fall into the designated position. Since the fixed and movable inclined plates are both arranged in an inclined state and do not form a complete plane, the contact area between the sludge cake and them is greatly reduced, thereby reducing the possibility of the sludge cake adhering to the fixed or movable inclined plates and effectively reducing the occurrence of sludge cake accumulation.

[0019] 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.

[0020] Please see Figures 1-4 A dewatering machine for preventing the accumulation of sludge by stacked screw presses includes a dewatering machine body 1. A fixed plate 2 is fixedly connected to the discharge port of the dewatering machine body 1. A frame 3 is fixedly connected to the bottom of the fixed plate 2. Multiple fixed inclined plates 4 are fixedly connected to the inner side of the frame 3. A movable inclined plate 5 is closely attached between adjacent fixed inclined plates 4. A sliding component is fixedly connected to the side of the movable inclined plate 5 away from the fixed inclined plate 4.

[0021] In this utility model of the anti-accumulation screw press sludge dewatering machine, when the sludge cake flows out of the main body 1 of the dewatering machine, it will fall onto the fixed inclined plate 4 of the frame 3. Subsequently, under the joint guidance of the fixed inclined plate 4 and the movable inclined plate 5, the sludge cake will finally fall into the designated position. Since both the fixed inclined plate 4 and the movable inclined plate 5 are arranged in an inclined state, and the two do not form a complete plane (e.g., Figure 1 and Figure 3 As shown in the figure, this significantly reduces the contact area between the mud cake and the fixed inclined plate 4 and the movable inclined plate 5, thereby reducing the possibility of the mud cake adhering to the fixed inclined plate 4 or the movable inclined plate 5, effectively reducing the occurrence of mud cake accumulation. At the same time, if mud cake still adheres to the fixed inclined plate 4 or the movable inclined plate 5 during long-term use of the dewatering machine body 1, the movable inclined plate 5 can be moved up and down along the tilt direction of the fixed inclined plate 4 by the sliding component, so that the fixed inclined plate 4 and the movable inclined plate 5 scrape against each other, allowing the mud cake to detach from the fixed inclined plate 4 or the movable inclined plate 5. In addition, since the dewatering machine body 1 is an existing mature product, it will not be described in detail here.

[0022] 3-5 sets of fixed inclined plates 4 are fixed to the inner side of the frame 3. Each set of fixed inclined plates 4 has an inclination angle of 35°±5°, a length of 200mm, and a width of 50mm. There are movable inclined plates 5 between adjacent fixed inclined plates 4, with a gap of ≤0.5mm between them and the fixed inclined plates 4, and the inclination angle is the same.

[0023] The sliding component has a groove 8 with a length of 80mm, a slider 11 with a stroke of 50mm, and a fit clearance of 0.15mm to ensure smooth reciprocating motion of the movable inclined plate 5 without jamming.

[0024] like Figure 2 and Figure 4 As shown, the sliding assembly includes a connecting plate 6, a side plate 7, and a slider 11. The connecting plate 6 is fixedly connected to the side of the movable inclined plate 5 away from the fixed inclined plate 4. The side plates 7 are fixedly connected to both sides of the connecting plate 6. A groove 8 is provided at the end of the side plate 7 away from the connecting plate 6. The slider 11 is slidably connected inside the groove 8. The slider 11 is fixedly connected to the outer wall of the frame 3.

[0025] Specifically, during the process of moving the movable inclined plate 5, the slider 11 and the slide 8 cooperate with each other to ensure that the movable inclined plate 5 always moves in the specified direction, and can prevent the movable inclined plate 5 from completely detaching from the frame 3, causing the mud cake to fall out from the side of the fixed inclined plate 4 near the dewatering machine body 1.

[0026] like Figure 2 and Figure 4 As shown, the end of slider 11 is trapezoidal. The trapezoidal design of slider 11 provides better restraint.

[0027] like Figure 2As shown, a slide rod 9 is slidably connected to the middle position of the slider 11, and the two ends of the slide rod 9 are fixedly connected to the two ends of the slide groove 8 respectively.

[0028] Specifically, during the movement of the movable ramp 5, the connecting plate 6, the side plate 7, and the sliding rod 9 will move together with the movable ramp 5, and the sliding rod 9 will play a positioning role, making the entire sliding process smoother.

[0029] like Figure 2 and Figure 4 As shown, a fixing bolt 12 is threadedly connected to the side of the slider 11 away from the frame 3, and the end of the fixing bolt 12 abuts against the slider 9.

[0030] Specifically, after the mud cake above the fixed inclined plate 4 and the movable inclined plate 5 is cleaned, the movable inclined plate 5 can be slid back to its original position, and then the fixing bolt 12 is tightened so that the end of the fixing bolt 12 abuts against the sliding rod 9, thereby fixing the movable inclined plate 5.

[0031] like Figure 2 As shown, the end of the fixing bolt 12 away from the slider 11 is hexagonal. The hexagonal design allows the fixing bolt 12 to be tightened both by a tool and manually.

[0032] like Figure 2 As shown, an elastic element 10 is sleeved on one end of the slide rod 9 near the connecting plate 6. One end of the elastic element 10 is fixedly connected to the end of the slide groove 8, and the other end of the elastic element 10 is fixedly connected to the slider 11.

[0033] Specifically, when resetting the movable inclined plate 5, simply loosen the connecting plate 6. Under the action of the elastic element 10, the movable inclined plate 5 will return to its original position, making the resetting of the movable inclined plate 5 simpler and more convenient. In addition, the elastic element 10 is preferably made of stainless steel or piano wire, which has a high fatigue limit and is suitable for long-term reciprocating motion. Its surface is nickel-plated or coated, which has strong corrosion resistance. The elastic force range of the elastic element 10 is about 10N-20N, and the specific elastic force value should be changed according to the actual application requirements. This elastic force range is to avoid the occurrence of elastic failure.

[0034] It is worth noting that if you want it to be fully automatic, you only need to remove the fixing bolts 12, then fix the cylinder to the bottom of the dewatering machine body 1 near the frame 3, the tilt direction of the cylinder is the same as the cleaning direction of the movable inclined plate 5, fix the output end of the cylinder to the connecting plate 6, and finally connect the cylinder to the control module (such as the control cabinet or central control room).

[0035] 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.
