Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a sludge dewatering machine device with good dewatering effect. Background Technology

[0002] Since sludge remains in a liquid state and has a large volume after concentration or digestion, it cannot be transported or disposed of. In order to further reduce the water content and make the sludge as low as possible, sludge dewatering machines are used to dewater the sludge, thereby reducing the sludge volume and facilitating transportation.

[0003] For example, the patent with publication number CN218262233U discloses a sludge dewatering machine, which includes a base, a dewatering tank, a placement port, a first cylinder, a pressure plate, a second cylinder, baffles, and a collection box. The sludge enters the dewatering tank through the placement port, and the pressure plate driven by the first cylinder repeatedly squeezes the sludge to dewater it. After dewatering, the second cylinder drives the two sets of baffles to move away from each other, so that the dewatered sludge falls into the collection box for collection.

[0004] Because the above-mentioned patent involves sludge entering the dewatering tank directly through the placement port during use, debris such as branches, gravel, and broken glass in the sludge can affect the pressure plate's compression of the sludge, resulting in poor water removal from the sludge. Therefore, it is necessary to design a sludge dewatering machine with good dewatering effect to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a sludge dewatering machine device with good dewatering effect, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sludge dewatering machine device with good dewatering effect, including a support plate, a support leg fixedly connected to the bottom of the support plate, and a dewatering box fixedly installed on the top of the support plate. The top of the dewatering box is connected to a feed inlet, and a cleaning mechanism is provided outside the feed inlet. The cleaning mechanism includes an installation frame, a filter screen, and a fixing frame. The installation frame is located on the top of the feed inlet, and a filter frame is provided on the top of the installation frame. The filter screen is fixedly installed inside the filter frame, and the fixing frame is fixedly connected to the outer wall of the installation frame. The bottom of the filter frame is inserted into the inside of the fixing frame.

[0007] Preferably, a vertical pole is fixedly connected to the top of the dehydration tank, a horizontal bar is fixedly connected to the top of the vertical pole, a slider is fixedly connected to the outer wall of the mounting frame, a sliding hole is provided on the horizontal bar, the slider is slidably connected inside the sliding hole, there are two horizontal bars, and the mounting frame slides between the two horizontal bars.

[0008] Preferably, a spring is provided inside the sliding hole, and the two ends of the spring are fixedly connected to the outer wall of the slider and the inner wall of the sliding hole, respectively. By providing the spring, the mounting frame can be driven to reset.

[0009] Preferably, a connecting plate is fixedly connected to the left side of the mounting frame, and a circular plate is provided on the left side of the connecting plate. An arc-shaped hole is opened on the left side of the connecting plate, and the arc-shaped hole fits with the outer wall of the circular plate to improve the squeezing effect.

[0010] Preferably, a motor is fixedly installed on the top of the dehydration tank, and the output shaft of the motor is fixedly connected to the bottom of the circular plate at a non-center position. The motor is used to drive the circular plate to move eccentrically.

[0011] Preferably, the fixed frame is threaded with fastening bolts, and an L-shaped plate is fixedly connected to the left side, with a striking rod fixedly connected to the inner wall of the L-shaped plate.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This sludge dewatering machine with good dewatering effect uses a filter screen to pre-filter the sludge poured into the filter frame, leaving behind debris such as branches, gravel, and broken glass. The filtered sludge then falls into the dewatering tank for further dewatering, thereby improving the dewatering effect. During the filtration process, the motor drives the circular plate to make an eccentric motion. The circular plate continuously squeezes the connecting plate, causing the mounting frame to repeatedly move left and right under the cooperation of sliding holes, sliders, and springs, thereby improving the filtration effect and preventing the filter screen from clogging.

[0014] 2. This sludge dewatering machine with good dewatering effect can fix the filter frame inside the fixed frame by setting fastening bolts. The filter frame can be disassembled by loosening the fastening bolts, which makes it easy to deal with the debris inside the filter frame. During the removal process, when the fixed frame moves left and right, it will drive the striking rod to repeatedly hit the feed port, thereby avoiding the adhesion of contaminants.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0023] Please see Figure 1-3One embodiment of this utility model is as follows: A sludge dewatering machine device with good dewatering effect includes a support plate 1, a support leg 2 fixedly connected to the bottom of the support plate 1, and a dewatering tank 3 fixedly installed on the top. A feed inlet 4 is connected to the top of the dewatering tank 3. A cleaning mechanism 5 is provided outside the feed inlet 4. The cleaning mechanism 5 includes a mounting frame 56, a filter screen 57, and a fixing frame 512. The mounting frame 56 is located on top of the feed inlet 4, and a filter frame 58 is provided on top of the mounting frame 56. The filter screen 57 is fixedly installed inside the filter frame 58. The fixing frame 512 is fixedly connected to the outer wall of the mounting frame 56, and the bottom of the filter frame 58 is inserted into the fixing frame 512. Inside, a vertical rod 51 is fixedly connected to the top of the dehydration tank 3, and a horizontal rod 52 is fixedly connected to the top of the vertical rod 51. A slider 54 is fixedly connected to the outer wall of the mounting frame 56. A sliding hole 53 is opened on the horizontal rod 52, and the slider 54 is slidably connected inside the sliding hole 53. There are two horizontal rods 52, and the mounting frame 56 slides between the two horizontal rods 52. A spring 55 is installed inside the sliding hole 53. The two ends of the spring 55 are fixedly connected to the outer wall of the slider 54 and the inner wall of the sliding hole 53, respectively. The spring 55 can drive the mounting frame 56 to return to its original position. When installing the impurity removal mechanism, the vertical rod 51 is first vertically fixed to the top of the dehydration tank 3 to ensure that it is stable and does not wobble. The connection between the horizontal rod 52 and the vertical rod 51 should be tight, and welding or high-strength bolts can be used to ensure that the horizontal rod 52 can withstand the force generated when the mounting frame 56 moves. When the slider 54 on the mounting frame 56 is installed in the sliding hole 53, the fitting accuracy between the slider 54 and the sliding hole 53 must be ensured to avoid jamming or excessive shaking. Before installation, the slider 54 and the sliding hole 53 can be cleaned and an appropriate amount of lubricating oil can be applied to reduce frictional resistance and extend service life. A connecting plate 59 is fixedly connected to the left side of the mounting frame 56. A circular plate 511 is set on the left side of the connecting plate 59. An arc-shaped hole is opened on the left side of the connecting plate 59. The arc-shaped hole fits with the outer wall of the circular plate 511 to improve the squeezing effect. A motor 510 is fixedly installed on the top of the dehydration tank 3, and the output shaft of the motor 510 is fixedly connected to the bottom of the circular plate 511 at the non-center point. The motor 510 is set to drive the eccentric movement of the circular plate 511. The model of the motor 510 is YE2-90L-4.

[0024] Working principle: Sludge is poured into the dewatering tank 3 for compression and dewatering. The device is equipped with a dewatering mechanism, a discharge mechanism, and a wastewater treatment mechanism, all of which are existing technologies. For details, please refer to the prior art in the background section. By setting up a filter screen 57, the sludge poured into the filter frame 58 is pre-filtered, leaving behind debris such as branches, gravel, and broken glass. The filtered sludge then falls into the dewatering tank 3 for further dewatering, thereby improving the dewatering effect. During the filtration process, the motor 510 drives the circular plate 511 to make eccentric movements. The circular plate 511 continuously squeezes the connecting plate 59, causing the mounting frame 56 to continuously drive the filter frame 58 to move left and right repeatedly under the cooperation of the sliding hole 53, the slider 54, and the spring 55, thereby improving the filtration effect and preventing the filter screen 57 from becoming clogged.

[0025] Please see Figure 2 Based on the above embodiments, in another embodiment of this utility model, a fastening bolt 8 is threadedly connected to the fixed frame 512, and an L-shaped plate 6 is fixedly connected to the left side. A striking rod 7 is fixedly connected to the inner wall of the L-shaped plate 6. There are two fastening bolts 8, two L-shaped plates 6, and two striking rods 7. The striking end of the striking rod 7 is made of rubber to avoid damaging the feed port 4. Its length is designed to match the range of left and right movement of the mounting frame 56.

[0026] Working principle: The filter frame 58 can be fixed inside the fixed frame 512 by setting the fastening bolt 8. The filter frame 58 can be disassembled by loosening the fastening bolt 8, which makes it easy to handle the debris inside the filter frame 58. During the impurity removal process, when the fixed frame 512 moves left and right, it will drive the striking rod 7 to repeatedly strike the feed port 4, causing the feed port 4 to vibrate, thereby preventing contamination from adhering.

[0027] It is worth noting that all the technologies not described in the above manual are existing technologies and are not the main innovations, so they will not be described in detail here.

[0028] This utility model provides a sludge dewatering machine device with good dewatering effect. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
