Description

Technical Field

[0001] This utility model relates to the field of sludge separation technology, specifically a sludge separation device for construction site wastewater treatment. Background Technology

[0002] At construction sites, wastewater is generated in large quantities and has a complex composition. If the large amount of sludge contained therein is discharged directly without effective treatment, it will cause serious pollution to the surrounding environment, such as clogging drainage pipes and polluting soil and water bodies.

[0003] Traditional sludge separation devices for construction site wastewater treatment have revealed some shortcomings in practical applications. In terms of filter plate cleaning, many devices have complex filter plate structures, requiring specialized tools to disassemble the entire device during cleaning, which consumes a lot of time and manpower, resulting in long equipment maintenance time and poor work continuity. This undoubtedly increases the operating costs of the construction site. Moreover, due to the inconvenience of cleaning, residual sludge on the filter plates is prone to accumulate, affecting the subsequent separation effect and reducing the efficiency of the equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sludge separation device for construction site wastewater treatment, which solves the problem of complex filter plate structure design and difficulty in disassembly and cleaning in sludge separation devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sludge separation device for construction site wastewater treatment includes: a base, with a separation structure fixedly connected to the outer wall of the top of the base; and a feeding structure, with the outer wall of the bottom of the feeding structure fixedly connected to the outer wall of the top of the base, and the outer wall of the feeding structure slidably connected to the inner wall of the separation structure. The separation structure includes a separation box, with connecting plates symmetrically slidably connected to the inner wall of the separation box, and a first arc-shaped filter plate and a second arc-shaped filter plate symmetrically slidably connected to the inner wall of the connecting plates. A positioning block is fixedly connected to the outer wall of the first arc-shaped filter plate, and a connecting block is fixedly connected to the outer wall of the second arc-shaped filter plate. A motor is fixedly connected to the outer wall of the separation box, and a filter cylinder is fixedly connected to the outer wall of the connecting plate.

[0009] Preferably, the outer wall of the first arc-shaped filter plate is in contact with the outer wall of the second arc-shaped filter plate, the outer wall of the motor shaft is fixedly connected to the outer wall of the connecting plate, the first and second arc-shaped filter plates are disposed outside the filter cylinder, the outer wall of the bottom of the separation box is fixedly connected to the outer wall of the top of the base, after the motor starts, the outer wall of the motor shaft is fixedly connected to the outer wall of the connecting plate, thereby driving the connecting plate to rotate, which in turn causes the filter cylinder to rotate, while the first and second arc-shaped filter plates are disposed outside the filter cylinder and are slidably connected to the connecting plate, and also rotate accordingly.

[0010] Preferably, the outer wall of the positioning block is provided with a positioning groove, the outer wall of the connecting block is symmetrically provided with sliding grooves, the inner wall of the sliding groove is slidably connected with a clamping block, the outer wall of the clamping block is fixedly connected with a pressure spring, and the outer wall of the clamping block away from the pressure spring is fixedly connected with a button.

[0011] Preferably, the outer wall of the pressure spring on the side away from the clamping block is fixedly connected to the inner wall of the slide groove, and the outer wall of the clamping block is slidably connected to the inner wall of the positioning groove. Pressing the button causes the clamping block to slide into the slide groove against the elastic force of the pressure spring, thereby disengaging the clamping block from the positioning groove and freeing the positioning block from the restriction of the connecting block, thus separating and disassembling the first arc-shaped filter plate and the second arc-shaped filter plate.

[0012] Preferably, the feeding structure includes a support plate, a feeding pipe is fixedly connected to the inner wall of the support plate, a spiral plate is fixedly connected to the outer wall of the feeding pipe, a connecting rod is fixedly connected to the inner wall of the spiral plate, and support rods are symmetrically fixedly connected to the outer wall of the support plate.

[0013] Preferably, the outer wall of the spiral plate is slidably connected to the inner wall of the filter cartridge, the outer wall of the spiral plate away from the support plate is rotatably connected to the inner wall of the connecting plate, the outer wall of the connecting rod is fixedly connected to the inner wall of the separation box near the support plate, and the outer wall of the connecting rod is fixedly connected to the outer wall of the separation box. During the rotation of the filter cartridge, because the spiral plate is slidably connected to the inner wall of the filter cartridge and rotatably connected to the inner wall of the connecting plate away from the support plate, and the connecting rod on the spiral plate is fixedly connected to the inner wall of the separation box, the sludge attached inside the filter cartridge will be scraped out along the spiral plate, thereby discharging the sludge from the inner wall of the filter cartridge.

[0014] (III) Beneficial Effects

[0015] This utility model provides a sludge separation device for construction site wastewater treatment. It has the following beneficial effects:

[0016] (i) This separation structure, through the positioning block and connecting block, allows for easy separation of the two filter plates after the sludge separation work is completed. If it is necessary to clean the fine sludge remaining in the first and second arc-shaped filter plates, simply press the button to allow the clamping block to overcome the elastic force of the pressure spring, thereby disengaging the clamping block from the positioning groove and easily separating the two filter plates for cleaning. Conversely, during installation, the clamping block is slid into the positioning groove, and under the action of the pressure spring, the filter plates are firmly connected, ensuring the smooth progress of the separation work. This design greatly shortens the equipment maintenance time, improves the ease of use and continuity of work of the equipment, and reduces the maintenance cost and manpower input at the construction site.

[0017] (ii) The feeding structure, through the cooperation of the spiral plate and the feed pipe, guides the wastewater to flow in. When the wastewater enters the filter cartridge through the feed pipe, it moves in a spiral motion with the spiral plate. This not only ensures that the wastewater enters the filter cartridge evenly, laying the foundation for subsequent separation, but also, with the help of the special structure of the spiral plate, effectively scrapes off the sludge attached to the inner wall of the filter cartridge during the separation process and discharges it, which greatly improves the device's sludge treatment capacity and efficiency.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a sludge separation device for construction site wastewater treatment, comprising: a base 1, a separation structure 2 fixedly connected to the outer wall of the top of the base 1, and a feeding structure 3, the outer wall of the bottom of the feeding structure 3 being fixedly connected to the outer wall of the top of the base 1, and the outer wall of the feeding structure 3 being slidably connected to the inner wall of the separation structure 2; the separation structure 2 includes a separation box 21, a connecting plate 22 symmetrically slidably connected to the inner wall of the separation box 21, a first arc-shaped filter plate 23 and a second arc-shaped filter plate 24 symmetrically slidably connected to the inner wall of the connecting plate 22, a positioning block 25 fixedly connected to the outer wall of the first arc-shaped filter plate 23, a connecting block 26 fixedly connected to the outer wall of the second arc-shaped filter plate 24, a motor 27 fixedly connected to the outer wall of the separation box 21, and a filter cylinder 28 fixedly connected to the outer wall of the connecting plate 22.

[0026] The outer wall of the first arc-shaped filter plate 23 is in contact with the outer wall of the second arc-shaped filter plate 24. The outer wall of the rotating shaft on the motor 27 is fixedly connected to the outer wall of the connecting plate 22. The first arc-shaped filter plate 23 and the second arc-shaped filter plate 24 are disposed outside the filter cylinder 28. The outer wall of the bottom of the separation box 21 is fixedly connected to the outer wall of the top of the base 1. After the motor 27 is started, the outer wall of the rotating shaft on the motor 27 is fixedly connected to the outer wall of the connecting plate 22, thereby driving the connecting plate 22 to rotate, which in turn causes the filter cylinder 28 to rotate. At the same time, the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24 are disposed outside the filter cylinder 28 and are slidably connected to the connecting plate 22, and also rotate accordingly.

[0027] The outer wall of the positioning block 25 is provided with a positioning groove 251, and the outer wall of the connecting block 26 is symmetrically provided with a sliding groove 261. The inner wall of the sliding groove 261 is slidably connected with a clamping block 262, the outer wall of the clamping block 262 is fixedly connected with a pressure spring 263, and the outer wall of the clamping block 262 away from the pressure spring 263 is fixedly connected with a button 264.

[0028] The outer wall of the pressure spring 263 away from the clamping block 262 is fixedly connected to the inner wall of the slide groove 261. The outer wall of the clamping block 262 is slidably connected to the inner wall of the positioning groove 251. Pressing the button 264 causes the clamping block 262 to slide into the slide groove 261 against the elastic force of the pressure spring 263, thereby causing the clamping block 262 to disengage from the positioning groove 251, so that the positioning block 25 is not restricted by the connecting block 26, and the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24 are separated and disassembled.

[0029] The feeding structure 3 includes a support plate 31, a feeding pipe 32 is fixedly connected to the inner wall of the support plate 31, a spiral plate 33 is fixedly connected to the outer wall of the feeding pipe 32, a connecting rod 34 is fixedly connected to the inner wall of the spiral plate 33, and support rods 35 are symmetrically fixedly connected to the outer wall of the support plate 31.

[0030] The outer wall of the spiral plate 33 is slidably connected to the inner wall of the filter cartridge 28. The outer wall of the spiral plate 33 on the side away from the support plate 31 is rotatably connected to the inner wall of the connecting plate 22. The outer wall of the connecting rod 34 is fixedly connected to the inner wall of the separation box 21 on the side close to the support plate 31. The outer wall of the connecting rod 34 is fixedly connected to the outer wall of the separation box 21. During the rotation of the filter cartridge 28, since the spiral plate 33 is slidably connected to the inner wall of the filter cartridge 28 and rotatably connected to the inner wall of the connecting plate 22 on the side away from the support plate 31, and the connecting rod 34 on the spiral plate 33 is fixedly connected to the inner wall of the separation box 21, the sludge attached inside the filter cartridge 28 will be scraped out along the spiral plate 33, thereby discharging the sludge from the inner wall of the filter cartridge 28.

[0031] During use, wastewater from the construction site enters the separation structure 2 through the feeding structure 3. The separation structure 2 is driven by the motor 27 to rotate the connecting plate 22, which separates the wastewater and sludge in the separation structure 2. At the same time, the spiral plate 33 in the feeding structure 3 scrapes out the sludge in the separation structure 2. The outer wall of the bottom of the separation box 21 is fixedly connected to the outer wall of the top of the base 1, providing stable support for the entire separation structure 2.

[0032] First, in the feeding structure 3, the support plate 31 and support rod 35 provide support, and the feed pipe 32 guides the wastewater inflow and provides stability. After the wastewater enters the filter cylinder 28, the motor 27 starts. The outer wall of the rotating shaft on the motor 27 is fixedly connected to the outer wall of the connecting plate 22, thereby driving the connecting plate 22 to rotate, which in turn causes the filter cylinder 28 to rotate. At the same time, the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24 are set outside the filter cylinder 28 and are slidably connected to the connecting plate 22, and also rotate. During the rotation of the filter cylinder 28, under the action of centrifugal force, the water in the wastewater is thrown out through the filter holes of the filter cylinder 28, while the sludge remains inside the filter cylinder 28. The wastewater thrown out from the filter cylinder 28 will fall into the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24. With rotation, because the filter holes of the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24 are smaller than the filter holes of the filter cylinder 28, the sludge will be further filtered and separated.

[0033] During the rotation of the filter cartridge 28, the spiral plate 33 is slidably connected to the inner wall of the filter cartridge 28 and rotates to connect to the inner wall of the connecting plate 22 on the side away from the support plate 31. At the same time, the connecting rod 34 on the spiral plate 33 is fixedly connected to the inner wall of the separation box 21. The sludge attached inside the filter cartridge 28 will be scraped out along the spiral plate 33, thereby discharging the sludge from the inner wall of the filter cartridge 28.

[0034] After sludge separation is completed, fine sludge will remain in the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24. At this time, the button 264 can be pressed to make the clamping block 262 slide into the slide groove 261 against the elastic force of the pressure spring 263, thereby making the clamping block 262 disengage from the positioning groove 251, so that the positioning block 25 is not restricted by the connecting block 26, and the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24 can be separated and disassembled for internal cleaning. Conversely, the clamping block 262 is slidably inserted into the symmetrical positioning groove 251. Under the action of the pressure spring 263, its outer wall slides and connects with the inner wall of the positioning groove 251, thereby realizing the connection and fixation of the first arc-shaped filter plate 23 and the second arc-shaped filter plate 24, ensuring that the two are relatively stable during the sludge separation process.
