Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sludge dewatering equipment, specifically relating to a material collection device for sludge collection. Background Technology
[0002] A pharmaceutical factory's wastewater treatment plant needs to regularly clean up the sludge it generates. If it is directly transported away by tanker truck, the treatment cost is high. The inventor has developed a solution by pumping the sludge into a screw press sludge dewatering machine for dewatering. The dewatered sludge is then bagged and transported by a loading device. The dewatering process increases the amount of sludge that can be transported at one time, thus reducing costs.
[0003] However, the existing screw press sludge dewatering machine is installed on the second floor, and the discharge port is connected to the outdoor area on the first floor through a pipe for bagging. During the bagging process, the woven bag is directly put on the discharge port of the pipe for bagging. This method is prone to causing the woven bag to fall off at the connection of the discharge pipe during the bagging process. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a sludge collection device that improves the working environment and enhances operational safety.
[0005] The technical solution adopted by this utility model is as follows: a material collection device for sludge collection, including a permeable plate, a first half-cone plate and a second half-cone plate. The lower end of the first half-cone plate is fixedly connected to the permeable plate. One circumferential side of the second half-cone plate is hinged to one circumferential side of the first half-cone plate. The other circumferential side of the second half-cone plate is connected to the other circumferential side of the first half-cone plate and locked by a detachable locking mechanism. After the first half-cone plate and the second half-cone plate are connected, a conical receiving cavity with a smaller upper part and a larger lower part is formed.
[0006] Furthermore, the taper of the first and second semi-conical plates is 0.12.
[0007] Furthermore, the second half-cone plate is hinged to the first half-cone plate via a hinge.
[0008] Furthermore, the aforementioned locking mechanism includes a pin, a first sleeve, and a second sleeve. The first sleeve is vertically fixed to the outside of the first semi-conical plate, and the second sleeve is vertically fixed to the outside of the second semi-conical plate. The first sleeve and the second sleeve remain coaxial after the first semi-push plate and the second semi-push plate are closed and connected. The upper end of the pin is provided with a limiting element, and the lower end is movably inserted into the first sleeve and the second sleeve. The limiting element abuts against the upper end of the first sleeve.
[0009] Furthermore, two of the aforementioned first sleeves are provided, located on the upper and lower sides of the second sleeve, respectively.
[0010] Furthermore, the aforementioned limiting component is provided with a through hole.
[0011] Furthermore, the above-mentioned material collection device uses two units, and the bottom of the permeable plate is equipped with wheels.
[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, when using this utility model, the second half-push plate is locked to the first half-push plate by a locking mechanism. The sludge bag is placed into the conical receiving cavity with its upper edge turned up to the upper port of the conical receiving cavity. The collecting device is moved so that the inlet of the sludge bag is aligned with the outlet of the discharge pipe to collect the sludge. When a set amount has been collected, the collecting device is moved to one side for sealing. An integrated high-speed sealing machine is used for sealing. After sealing, the second half-push plate is opened by the locking mechanism to remove the sludge bag from the conical receiving cavity. After removal, the second half-push plate is closed, and another sludge bag is installed for the next round of sludge collection. The conical structure of the receiving cavity makes it easy for the top of the sludge bag to not slip after installation, improving the reliability of the connection between the sludge bag and the top of the collecting device. It also facilitates the positioning of the top of the sludge bag and allows the sludge to gradually accumulate after falling, avoiding affecting the sliding of the sludge bag. This structure is convenient and quick to operate. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1: As Figure 1-7As shown, a sludge dewatering device for a wastewater treatment plant includes a sludge dewatering machine 1, a discharge pipe 2, and a collection device 3. The sludge dewatering machine 1 is a screw press type sludge dewatering machine. The sludge dewatering machine 1 is installed on the second floor 401 of building 4. The discharge port of the sludge dewatering machine 1 is connected to one end of the discharge pipe 2. The other end of the discharge pipe 2 passes through the floor slab of the second floor 401 and the outer wall 4021 of the first floor 402 of building 4 and extends to the top of the collection device 3. The collection device 3 is installed on a water collection device 6. The water collection device 6 is connected to the wastewater discharge ditch 8 of the wastewater treatment plant through a drain pipe 7. The wastewater collected by the water collection device is discharged into the wastewater discharge ditch and then flows into the treatment device of the wastewater treatment plant for treatment to avoid environmental pollution. The collection device 3 is used to hold sludge bags 9, which are woven bags.
[0022] The sludge from the sludge dewatering machine installed on the second floor is led to the outdoor area on the first floor through a discharge pipe. A collection device is used to collect the sludge, and the seepage water is collected and discharged into the sewage ditch through a water collection device. This effectively prevents a large amount of sewage from seeping onto the ground, improves the working environment, avoids slippery ground, and improves the safety of workers. Moreover, the use of a collection device to place sludge bags for sludge collection is convenient and quick, effectively solving the problem that the sludge bags tied to the discharge pipe outlet in the existing technology are prone to falling off, resulting in better collection reliability.
[0023] Specifically, such as Figure 5 As shown, in this embodiment, the discharge pipe 2 has a bent structure near the upper end, bending to the right to buffer and slow down the falling sludge, preventing the sludge from falling into the pipe and causing excessive impact on the pipe due to excessive drop, thus avoiding damage to the discharge pipe and reducing maintenance costs. The top of the discharge pipe 2 is fixedly connected to the feed hopper 10, and one side of the feed hopper 10 is welded to the frame 101 of the sludge dewatering machine 1, which facilitates sludge collection and prevents it from falling near the sludge dewatering machine 1 and causing a deterioration of the working environment.
[0024] Specifically, such as Figure 3-4As shown, in this embodiment, the material collection device 3 includes a permeable plate 301, a first semi-conical plate 302, and a second semi-conical plate 303. The permeable plate 301 is provided with through holes 315 for water seepage, allowing water seeping from the sludge bag to flow into the water collection device. The lower end of the first semi-conical plate 301 is fixedly connected to the permeable plate 301. One circumferential side of the second semi-conical plate 303 is hinged to one circumferential side of the first semi-conical plate 302. The other circumferential side of the second semi-conical plate 303 is connected to the other circumferential side of the first semi-conical plate 302 using a detachable locking mechanism. The first half-conical plate 302 and the second half-conical plate 303 are connected to form a conical receiving cavity 305, which is smaller at the top and larger at the bottom. The sludge bag 9 is placed in the conical receiving cavity 305, and the upper end of the sludge bag 9 is open and turned up to the upper end of the conical receiving cavity 305 to form a limiting structure. The collecting device of this structure is directly opposite the discharge port of the discharge pipe, which can prevent sludge from falling into the sludge bag. In use, the second half-push plate is locked to the first half-push plate by the locking mechanism, and the sludge bag is placed into the conical receiving cavity with its upper end turned up to the conical receiving cavity. At the upper port, the moving collection device aligns the sludge bag's inlet with the discharge outlet of the discharge pipe to collect the sludge. Once a set amount has been collected, the moving collection device is moved to one side for sealing. An integrated high-speed sealing machine (GK9-350D model manufactured by Wenzhou Ruigong Sewing Machine Co., Ltd., patent application number 201620468506X) is used for sealing. After sealing, the second half-push plate is opened via the locking mechanism to remove the sludge bag from the conical receiving cavity. After removal, the second half-push plate is closed, and the bag is then installed... Another sludge bag is used for the next round of sludge collection. The conical structure of the receiving cavity makes it easy to install the sludge bag without the top slipping off. It also facilitates the positioning of the sludge bag with the top open and allows the sludge to gradually accumulate after falling, avoiding affecting the sliding of the sludge bag. This structure is convenient and quick to operate. The second half-cone plate 303 and the first half-cone plate 302 are hinged by two hinges 313. The hinges 313 are arranged on the outside of the joint between the second half-cone plate 303 and the first half-cone plate 302 to avoid scratching the sludge bag. To improve the connection stability between the first half-push plate 302 and the permeable plate 301, multiple reinforcing ribs 311 are welded to the outer periphery of the first half-push plate 302. The reinforcing ribs 311 are welded and fixed to the permeable plate 301. The upper ends of the second half-cone plate 302 and the first half-cone plate 303 are provided with arc-shaped outward flanges 312. The arc-shaped outward flanges 312 can fix the sludge bag 9 with rubber bands 316 after the sludge bag is turned over, further improving the connection reliability of the upper end of the sludge bag and ensuring the stability of the opening.
[0025] Specifically, the taper of the first half-cone plate 301 and the second half-cone plate 302 is 0.12, which is (diameter of the bottom of the cone-shaped cavity - diameter of the top of the cone) / height of the cone. The height of the cone is less than one-eighth of the height of the sludge bag, which facilitates the sludge bag to be turned over and the bag opening is limited.
[0026] Specifically, in this embodiment, the locking mechanism 304 includes a pin 306, a first sleeve 307, and a second sleeve 308. The first sleeve 307 is vertically fixed to the outside of the first semi-conical plate 302, and the second sleeve 308 is vertically fixed to the outside of the second semi-conical plate 303. The first sleeve 307 and the second sleeve 308 remain coaxial after the first semi-push plate 302 and the second semi-push plate 303 are closed and connected. The upper end of the pin 306 is provided with a limiting member 309, and the lower end is movably inserted into the first sleeve 307 and the second sleeve 308. Inside the tube 308, the limiting member 309 abuts against the upper end of the first sleeve 307. The locking mechanism, consisting of the pin 306, the first sleeve 307, and the second sleeve 308, is easy to operate, reliable to lock, and easy to manufacture. Specifically, two first sleeves 307 are provided, located on the upper and lower sides of the second sleeve 308 respectively, so that the pin can be subjected to symmetrical force, making the locking more reliable. In order to facilitate the removal of the pin, the limiting member 309 is provided with a through hole 310. The limiting member 309 can achieve this function by welding a nut to the top of the pin 306.
[0027] In order to ensure that sludge collection does not stop during the bag sealing process, two collection devices 3 are used. The bottom of the permeable plate 301 of the collection device 3 is equipped with four omnidirectional wheels 314, which facilitate the movement of the collection device, saving time and effort.
[0028] Specifically, such as Figure 1-2 As shown, the water collection device 6 in this embodiment includes an operating bed frame 601 and a water collection tray 602. The operating bed frame 601 has baffles 603 on all four sides forming receiving cavities. These cavities collect water seeping from the sludge bags. A permeable hole 604 is provided in the center of the receiving cavity, allowing the collected water to flow out. The water collection tray 602 has a water collection cavity 607 with an opening at the top. The water collection tray 602 is installed at the bottom of the operating bed frame 601 and directly opposite the permeable hole 604. The outlet of the water collection tray 602 is connected to a drain pipe 7, and water flows into the water collection tray through the permeable hole. The water is collected and drained away through a drain pipe. The water collection device has a simple structure, is easy to manufacture, and has a low cost. Specifically, the operating bed frame 601 has a square structure with four first support legs 605 at the four corners of the bottom. The four support legs 605 suspend the operating bed frame 601 in the air, which facilitates the installation of the water collection tray 602 at the bottom. The four corners of the bottom of the water collection tray 602 have four second support legs 606, which can bring the water collection tray as close as possible to the water permeable hole for collection. The two support legs on the left side are short, so that the water collection tray is tilted to the lower left. The drain pipe is connected to the left side of the water collection tray.
[0029] The operating bed frame is a workbench that allows people to stand on it and enables the two material collection devices (bag-making trolleys) to interchange positions. It has water-blocking edges around its perimeter, and the workbench has water-filtering holes in some areas. There is a water collection tray below the water-filtering holes to collect the water generated during bagging (rinsing water used for cleaning after production).
[0030] Specifically, in this embodiment, a flow-stopping valve 5 is installed at the end of the discharge pipe 2, such as... Figure 6-7 As shown, the shut-off valve 5 includes a valve plate 501, a telescopic rail 502, and a support frame 503. The telescopic rail 502 adopts a common three-section drawer rail. The width of the valve plate 501 is larger than the diameter of the discharge pipe 2, which can meet the requirement of sealing the discharge pipe outlet. The two sides of the valve plate 501 are respectively fixedly connected to the two telescopic ends of the two telescopic rails 502. The two fixed ends of the two telescopic rails 502 are fixedly connected to the two support frames 503. The two support frames 503 are fixedly connected to the wall surface of the outer wall 4021. After the valve plate 501 is pulled out from the telescopic rail 502, it can seal the outlet. At both ends of the discharge pipe, a pull-out shut-off valve is installed at the discharge port, which can quickly and temporarily block the discharge pipe. This is convenient and quick, effectively preventing sludge from falling onto the water collection device and causing inconvenience in cleaning. A blind hole 504 is provided on the wall opposite the telescopic rail 502, allowing for easy insertion of a section of the rail for easy extension and retraction after installation at the inner end, ensuring the extension range. The support frame 503 is an L-shaped angle steel frame, including a horizontal angle steel section 5031 and a vertical angle steel section 5032 fixedly connected to the horizontal angle steel section 5031. The horizontal angle steel section 5031 is fixed... The vertical angle steel 5032 is fixedly connected to the fixed end of the telescopic rail 502 and fixedly connected to the wall surface of the outer wall 4031 by two expansion bolts 5033. A vertical strip-shaped through hole 5034 is provided in the vertical angle steel 5032 at the connection point of the expansion bolts 5033. The angle steel support frame has a simple structure, good support rigidity and strength, and stable and reliable support. The vertical strip-shaped through hole facilitates vertical position adjustment, thereby adjusting the sealing effect of the valve plate on the discharge pipe. The vertical angle steel 5032 of the two support frames 503 are fixed together by a connecting plate 5035. The fixed connection serves to reinforce the two support frames and allows for simultaneous height adjustment of the two support frames, making adjustment more convenient. A support frame 505 is fixedly connected to the bottom circumference of the valve plate 501 by welding. The fixed ends of the telescopic rail 502 are fixedly connected to both sides of the support frame 505. The use of the support frame provides better support stability and facilitates the fixed connection of the telescopic rail. A cross-shaped reinforcing strip 506 is provided in the middle of the support frame 505, which improves the support rigidity of the valve plate, ensures flatness, and seals the outlet of the discharge pipe. Specifically, the top surface of the valve plate 501 is higher than the telescopic rail 502. An operating handle 507 is provided on the left or right side of the valve plate. By pulling the valve plate back and forth using the operating handle, the sealing operation of the discharge pipe can be easily performed.
