Description

Technical Field

[0001] This utility model relates to the technical field of sludge dewatering equipment, and more specifically, to a sludge dewatering equipment capable of cleaning its inner wall. Background Technology

[0002] The sludge currently being treated originates from concentrated sludge from wastewater treatment plants. After pretreatment, its moisture content is between 75% and 90%. Since industrial sludge contains many toxic components, it cannot be directly discharged and therefore needs to be treated.

[0003] Existing sludge dewatering equipment commonly uses detachable rotating drums, which require manual cleaning after dewatering. This reliance on manual operation results in low efficiency and poor effectiveness, affecting cleaning speed and subsequent equipment use. Furthermore, the cleaning components cannot be adjusted according to the equipment's inner diameter, meaning that the same cleaning system cannot serve various sizes of processing equipment, reducing the equipment's flexibility and practicality.

[0004] Therefore, a sludge dewatering device capable of cleaning the inner wall is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sludge dewatering device capable of cleaning the inner wall, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge dewatering device capable of cleaning the inner wall, comprising a processing device, a cover plate detachably installed on the top of the processing device, a motor detachably installed above the cover plate, a rotating shaft connected to the output end of the motor, fixed rods installed on the outer side of the rotating shaft, a telescopic rod movably connected inside the fixed rod, a positioning hole opened above the telescopic rod, a sliding rod fixedly connected to the end of the telescopic rod away from the fixed rod, a sliding groove opened inside the sliding rod, a positioning rod slidably installed inside the sliding rod, the positioning rod being positioned along the sliding groove opened in the sliding rod, and a cleaning brush fixedly installed on the upper side of the positioning rod.

[0007] Preferably, a sieve plate is detachably placed inside the processing device, and the bottom of the sieve plate is closely attached to the upper part of a limiting block installed inside the processing device.

[0008] Preferably, a pin is provided on the upper side of the fixing rod, and the fixing rod and the telescopic rod are positioned by the pin.

[0009] Preferably, a cleaning rod is fixedly installed at the bottom of the rotating shaft, and the bottom of the cleaning rod is in contact with the upper surface of the screen plate.

[0010] Preferably, a fixing block is fixedly installed on the upper side of the cover plate, and a fixing block is also fixedly connected to the processing equipment at the position overlapping with the cover plate. A positioning pin is detachably installed on the upper side of the fixing block.

[0011] Preferably, a branch water pipe is fixedly connected to one side of the treatment equipment, a water pump is fixedly connected to the upper side of the branch water pipe, a drain pipe is fixedly connected to one side of the treatment equipment, and a valve is fixedly connected to the end of the drain pipe away from the treatment equipment.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Compared with existing technologies, this sludge dewatering equipment, which can clean the inner wall, drives the output shaft to rotate efficiently by starting the motor, which in turn drives the positioning rods on both sides to rotate synchronously.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] As attached Figures 1 to 3 The sludge dewatering device shown includes a processing device 1. A cover plate 3 is detachably installed on the top of the processing device 1. A motor 4 is detachably installed on the top of the cover plate 3. The output end of the motor 4 is connected to a rotating shaft 5. Fixed rods 6 are installed on the outer side of the rotating shaft 5. A telescopic rod 7 is movably connected inside the fixed rod 6. A positioning hole 8 is opened on the top of the telescopic rod 7. A sliding rod 11 is fixedly connected to the end of the telescopic rod 7 away from the fixed rod 6. A sliding groove is opened inside the sliding rod 11. A positioning rod 12 is slidably installed inside the sliding rod 11. The positioning rod 12 is positioned along the sliding groove opened in the sliding rod 11. A cleaning brush 13 is fixedly installed on the upper side of the positioning rod 12.

[0022] Specifically, by starting the motor 4, the output shaft 5 is driven to rotate efficiently, which in turn drives the positioning rods 12 on both sides to rotate synchronously. Because the cleaning brush 13 is closely attached to the inner wall of the processing equipment 1, the rotation of the positioning rods 12 can thoroughly and meticulously clean the inside of the processing equipment 1, effectively removing residues and dirt from the inside of the sludge dewatering equipment. This ensures the cleanliness and operating efficiency of the sludge dewatering equipment in subsequent use, greatly reducing usage problems caused by improper cleaning. At the same time, this design takes into account the different inner diameter requirements that the processing equipment 1 may have. The fixed rod 6 is designed with a movable slot for the telescopic rod 7, giving the cleaning brush 13 flexibility in position adjustment. When adapting to different sizes of processing equipment 1, the user only needs to pull the pin 9 out of the locking hole of the fixing rod 6 to unlock the telescopic rod 7, allowing it to extend and retract freely within the range of the fixing rod 6. No additional tools are required, greatly improving the ease of use. After adjusting to the appropriate cleaning position, the user inserts the pin 9 back into the corresponding hole of the fixing rod 6 to achieve a secure lock, ensuring that the cleaning brush 13 will not shift due to vibration or rotation during the cleaning process. This guarantees the stability and reliability of the cleaning work, improves the versatility and adaptability of the equipment, and enables the same cleaning system to serve multiple sizes of processing equipment 1, reducing the user's equipment investment and maintenance costs.

[0023] Example 2

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:

[0025] In a preferred embodiment, a sieve plate 2 is detachably placed inside the processing device 1, with the bottom of the sieve plate 2 closely attached to the upper part of a limiting block installed inside the processing device 1. Furthermore, the limiting block inside the processing device 1 effectively stabilizes and limits the sieve plate 2, ensuring its stability and reliability within the tank. The sieve plate 2 can finely filter out larger impurity particles adhering to the inner wall of the tank. Through the filtering action of the sieve plate 2, larger impurities are effectively trapped above the sieve plate 2, thereby preventing them from being directly discharged from the processing device 1 during the cleaning process, which could potentially cause equipment blockage or environmental pollution.

[0026] In a preferred embodiment, a pin 9 is provided on the upper side of the fixing rod 6, and the fixing rod 6 and the telescopic rod 7 are positioned by the pin 9. Furthermore, the pin 9 is made of a specific high corrosion-resistant material, which fundamentally prevents the pin 9 from suffering severe corrosion damage when exposed to the complex and ever-changing water environment inside the treatment equipment 1 for a long time. The water environment inside the treatment equipment 1 may contain various chemicals, impurities, and acid and alkali solutions of different concentrations. The pin 9 can not only effectively resist the erosion of these corrosive substances, but also maintain its original strength and precision during long-term use, ensuring that the connection between the fixing rod 6 and the telescopic rod 7 is both firm and reliable. The pin 9 locks the relative position of the fixing rod 6 and the telescopic rod 7, so that the two parts can work together to undertake the task of supporting and adjusting the internal structure of the treatment equipment 1.

[0027] In a preferred embodiment, a cleaning rod 10 is fixedly installed at the bottom of the rotating shaft 5, and the bottom of the cleaning rod 10 contacts the upper surface of the screen plate 2. Furthermore, the cleaning rod 10 enables direct contact with the screen plate 2, solving the problem of difficult-to-clean mud accumulation on the surface of the screen plate 2. During the operation of the processing equipment 1, the screen plate 2, as a component for filtering impurities, often accumulates a certain amount of mud and fine particles on its surface. If these accumulations are not cleaned in time, they will not only reduce the filtration efficiency of the screen plate 2 but may also cause blockage of the screen holes, thus affecting the normal operation of the entire processing system. The cleaning rod 10, through close contact with the screen plate 2, utilizes mechanical friction or a specially designed cleaning mechanism, such as brushes or scrapers, to effectively clean the surface of the screen plate 2, removing mud and impurities, restoring the permeability of the screen holes, and ensuring that the screen plate 2 maintains its high-efficiency filtration performance. In addition, the cleaning rod 10 is usually connected to the drive mechanism, greatly reducing the labor intensity of the operators and improving cleaning efficiency and accuracy.

[0028] In a preferred embodiment, a fixing block 14 is fixedly installed on the upper side of the cover plate 3, and a fixing block 14 is also fixedly connected to the processing device 1 at the overlapping position with the cover plate 3. A positioning pin 15 is detachably installed on the upper side of the fixing block 14. Furthermore, by setting the fixing block 14 at the overlapping position of the processing device 1 and the cover plate 3, the two are ensured to be precisely aligned. The positioning pin 15 passes through the fixing block 14 to form a stable positioning lock. When the cover plate 3 needs to be placed on the processing device 1, the operator only needs to align the reserved hole of the fixing block 14 on the cover plate 3 with the fixing block 14 on the upper side of the processing device 1, and pass the positioning pin 15 through the reserved hole to achieve precise positioning of the two, reducing the difficulty of operation and significantly improving the installation efficiency and accuracy.

[0029] In a preferred embodiment, a diversion pipe 16 is fixedly connected to one side of the treatment device 1, and a water pump 17 is fixedly connected to the upper side of the diversion pipe 16. A drain pipe 18 is fixedly connected to one side of the treatment device 1, and a valve 19 is fixedly connected to the end of the drain pipe 18 away from the treatment device 1. Furthermore, by utilizing the diversion pipe 16 and the powerful pump 17, external water can be efficiently drawn and injected into the treatment device 1. The diversion pipe 16 acts as a guide, ensuring that the water flow can enter the treatment device 1 evenly and stably. This avoids problems such as excessive local pressure or uneven water flow caused by water flow impact. At the same time, the control of water pump 17 makes the water pumping process both efficient and energy-saving, meeting the needs under different working conditions. After the treatment equipment 1 completes its treatment task, the water stored at the bottom of the tank needs to be discharged through drain pipe 18, which can quickly discharge the treated water and avoid problems such as equipment corrosion or reduced treatment efficiency caused by water accumulation. Valve 19, as a water flow regulator, can be flexibly adjusted according to actual needs, thereby achieving precise control of the water output speed.

[0030] The working process of this utility model is as follows: In use, firstly, when cleaning the inside of the sludge dewatering equipment is required, the water pump 17 is started, which efficiently draws external water and injects it into the interior of the treatment equipment 1. The diversion pipe 16 acts as a guide. Simultaneously, the motor 4 is started, which drives the output shaft 5 to rotate, achieving the purpose of rotating the positioning rods 12 on both sides. A cleaning brush 13 is installed on the upper side of the positioning rods 12. The cleaning brush 13 contacts the interior of the treatment equipment 1, cleaning the inner wall of the treatment equipment 1 and preventing problems from occurring during subsequent use, thus affecting its operation. At the same time, a cleaning brush 13 is installed at the bottom of the rotating shaft 5. The cleaning rod 10 directly contacts the screen plate 2, solving the problem of mud accumulation on the surface of the screen plate 2, which is difficult to clean. It effectively cleans the surface of the screen plate 2, removing mud and impurities. The water stored at the bottom of the tank needs to be discharged through the drain pipe 18, which can quickly drain the treated water. Since the telescopic rod 7 is inserted into the fixed rod 6, when the position of the cleaning brush 13 needs to be adjusted, the pin 9 needs to be removed from the fixed rod 6 and telescopically extended inside the fixed rod 6. When the cleaning brush 13 is adjusted to the appropriate position, the pin 9 is inserted back into the fixed rod 6, which is convenient for use by processing equipment 1 with different inner diameters.
