Description

Technical Field

[0001] The invention belongs to the technical field of sludge dewatering, and in particular relates to a sludge dewatering high-pressure belt machine with a self-cleaning function. Background Art

[0002] Sludge dewatering high-pressure belt conveyors play a vital role in sludge treatment. They are primarily used to remove moisture from sludge, converting it into a mud cake with a lower moisture content, thereby reducing the volume and weight of the sludge and facilitating subsequent processing and disposal. Sludge dewatering high-pressure belt conveyors effectively squeeze out moisture from the sludge through high pressure and mechanical extrusion, reducing the sludge's moisture content, volume, and weight, thereby reducing transportation and processing costs. With the development of the modern construction industry, sludge treatment and reuse are becoming increasingly frequent in order to save construction costs.

[0003] However, the existing sludge dewatering high-pressure belt equipment has the following disadvantages during use:

[0004] 1. During the use of existing sludge dewatering high-pressure belt conveyor equipment, the upper end of the sludge dewatering mainly relies on the conveyor filter belt to transport the sludge. During the transportation process, the sludge is squeezed out of the water in the sludge by contact with the squeezing roller above the equipment, and the sludge is filtered and collected to achieve the purpose of sludge dewatering. This operation mode means that the sludge can only be dehydrated within the limit of the distance between the squeezing roller and the conveyor belt during squeezing dehydration. A large amount of water is still stored in the sludge and is not separated, thereby reducing the dehydration effect of the equipment;

[0005] 2. Ordinary sludge dewatering high-pressure belt equipment requires staff to feed a fixed amount of sludge into the equipment for dewatering before dewatering. This feeding method requires staff to always pay attention to the amount of sludge input to avoid excessive feeding that leads to untimely equipment extrusion, and too little feeding that affects dewatering efficiency. Direct feeding may cause the water to be unable to be fully separated for sludge with a high water content. Ordinary sludge dewatering high-pressure belt machines do not have a drainage function before feeding, which reduces the dewatering efficiency of the equipment and increases the workload of staff.

[0006] 3. During the pressure dehydration process of the existing sludge dewatering high-pressure belt conveyor equipment, a large amount of mud will adhere to the various squeezing rollers and conveyor belt surfaces at the upper end, which requires staff to manually scrape them off later. The upper end of ordinary dewatering belt conveyor equipment does not have a self-cleaning function, and manual cleaning in the later stage is very troublesome and difficult to clean, thereby reducing the convenience of using the device.

[0007] Therefore, it is necessary to invent a sludge dewatering high-pressure belt machine with a self-cleaning function to solve the above problems. Summary of the Invention

[0020] Technical effects and advantages of the present invention:

[0021] 1. The present invention is provided with a high-pressure dehydration mechanism. The sludge is initially squeezed and dehydrated through the first water filtering conveyor belt in cooperation with the first squeezing roller and then transferred to the second water filtering conveyor belt. The first electric push rod and the second electric push rod are activated to push the first connecting frame and the second connecting frame respectively, and then the third squeezing roller and the fourth squeezing roller located on the upper and lower sides of the upper surface of the second water filtering conveyor belt squeeze both sides of the upper surface of the second water filtering conveyor belt together. As the second water filtering conveyor belt continues to convey, the sludge is transferred between the third squeezing roller and the fourth squeezing roller on both sides.

At the same time, the sludge is also pressurized to quickly squeeze out the water therein, thereby improving the dehydration effect.

[0022] 2. The present invention provides a drainage-type feeding mechanism to directly pour the sludge into the feed hopper. During the feeding process, the water in the sludge falls by its own gravity onto the pad, enters the bottom of the inner wall of the feed hopper through the filter holes on the pad, and enters the water collection area below the inner wall of the dehydrator through the water guide pipe for collection. This device serves the purpose of drainage during the feeding process, and the uninterrupted feeding of the auger allows the sludge to enter the dehydrator in an orderly and quantitative manner for dehydration. There is no need for staff to pay attention to and manually introduce the sludge in a quantitative manner, which reduces the workload of staff and improves the dehydration efficiency of the equipment.

[0023] 3. The present invention sets a self-cleaning mechanism, cooperates with the first scraper and the second scraper, and starts the cleaning nozzle after dehydration is completed. The water in the water tank is introduced into the inner wall of the dehydrator through the water inlet pipe, the connecting pipe and the hose and sprayed and aerated. At the same time, the first water filter conveyor belt and the second water filter conveyor belt are driven during the flushing process. The sludge on the surface of the first scraper and the second scraper is scraped off, making it cleaner and eliminating the need for manual disassembly and cleaning by the staff, thereby improving the convenience of using the device.

DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The present invention provides Figure 1-8The sludge dewatering high-pressure belt conveyor with self-cleaning function shown in the figure comprises a dewatering machine 1, the upper end of which is provided with a high-pressure dewatering mechanism 2, a drainage-type feeding mechanism 6 and a self-cleaning mechanism 7;

[0037] The high-pressure dehydration mechanism 2 includes a mounting frame 201 installed at the upper edge of one end of the inner wall of the dehydrator 1, a first water filtering conveyor belt 202 is installed at the lower edge of the other end of the inner wall of the dehydrator 1, one end of the inner wall of the dehydrator 1 is in an inclined state, and a second water filtering conveyor belt 203 is installed on the inner wall of the dehydrator 1 above the inclined surface, and one end of the second water filtering conveyor belt 203 is below one end of the first water filtering conveyor belt 202, the inner wall of the dehydrator 1 is located above the first water filtering conveyor belt 202 and is rotatably connected to a plurality of first squeezing rollers 204, the inner wall of the dehydrator 1 is located above one end of the second water filtering conveyor belt 203 and is rotatably connected to a second squeezing roller 205, and the mounting frame 201 is located above one end of the second water filtering conveyor belt 203. A first electric push rod 208 is installed at the bottom, and a first connecting frame 206 is fixedly provided at the output end of the first electric push rod 208. The inner walls of both ends of the first connecting frame 206 are equidistantly connected to third squeezing rollers 207 for rotation. A support frame 209 is installed below the outer wall of one end of the dehydrator 1. A second connecting frame 210 is fixed between the two ends of the support frame 209. A plurality of fourth squeezing rollers 211 are equidistantly connected to the inner wall of the second connecting frame 210 for rotation. A support plate 212 is fixedly provided on one side of the bottom of the dehydrator 1, and a second electric push rod 213 is fixedly provided on one side of the top of the support plate 212. The output end of the second electric push rod 213 is fixedly connected to the bottom of the support frame 209.

[0038] During use, the sludge is loaded through the drainage-type loading mechanism 6, so that the sludge is orderly introduced into the first water filtering conveyor belt 202 inside the dehydrator 1, and is conveyed and guided by the first water filtering conveyor belt 202 to the bottom of the multiple first squeezing rollers 204. By driving the rotating first squeezing rollers 204 to rotate and cooperate with the first water filtering conveyor belt 202 to rotate and squeeze together, the sludge is quickly squeezed and flattened and presented on the first water filtering conveyor belt 202, and the water contained in it is initially squeezed out and filtered through the first water filtering conveyor belt 202 and collected under the dehydrator 1, and then the sludge is transferred to the second water filtering conveyor belt 203 through the transfer of the first water filtering conveyor belt 202, and continues to be conveyed, passing above the second water filtering conveyor belt 203 The second squeezing roller 205 squeezes the sludge again and flattens it to be transferred to the second water filtering conveyor belt 203. When it is transferred to one end, the first electric push rod 208 and the second electric push rod 213 are started to push the first connecting frame 206 and the second connecting frame 210 respectively, so that the third squeezing roller 207 and the fourth squeezing roller 211 located on the upper and lower sides of the upper surface of the second water filtering conveyor belt 203 squeeze both sides of the upper surface of the second water filtering conveyor belt 203 together. As the second water filtering conveyor belt 203 continues to be conveyed, the sludge is transferred between the third squeezing roller 207 and the fourth squeezing roller 211 on both sides. The mutual rolling of the squeezing rollers on both sides makes the sludge pass smoothly, and at the same time, it is pressurized to quickly squeeze out the water therein, thereby improving the dehydration effect.

[0039] Furthermore, one end of each first squeezing roller 204 passes through the outer wall of one side of the dehydrator 1 and is fixedly connected to a gear 3, the outer wall of each gear 3 is meshed with a toothed belt 4, a first motor 5 is installed on the other side of the outer wall of the dehydrator 1, and the other end of one of the first squeezing rollers 204 passes through the outer wall of the other side of the dehydrator 1 and is fixedly connected to the output end of the first motor 5, and when the sludge starts to be fed into the dehydrator 1 from the drainage feeding mechanism 6, its accumulation thickness is relatively large. Therefore, when the first squeezing roller 204 cooperates with the first water filtering conveyor belt 202 to squeeze together, it is driven by the first motor 5 and driven by the meshing transmission of the gear 3 and the toothed belt 4 so that each first squeezing roller 204 can rotate on its own, thereby more powerfully and effectively cooperating with the first water filtering conveyor belt 202 to squeeze the sludge flat, as shown in the attached instruction manual. Figure 5 As shown;

[0040] Further, as the instructions Figure 6 As shown, the drainage-type feeding mechanism 6 includes a feed hopper 601 installed at one end of the dehydrator 1. A fixing frame 602 is fixed on one side of the top of the feed hopper 601, and a rotating shaft 603 is rotatably connected to one side of the bottom of the fixing frame 602. When feeding, the sludge can be directly poured into the feed hopper 601.

[0041] An auger 604 is fixedly provided at one end of the rotating shaft 603, and the outer wall of the auger 604 is interlaced with the inner wall of the feed hopper 601. A feed trough 605 is provided on one side of the feed hopper 601. The inner wall of the feed hopper 601 is located below the auger 604 and is equipped with a pad 606. After the sludge is poured in, it falls directly into the feed hopper 601 and is located above the auger 604. At this time, the second motor 609 is started to drive the auger 604 to rotate, and then during the rotation of the auger 604, the sludge is introduced into the bottom of the feed hopper 601, and enters the dehydrator 1 from the feed trough 605 below the feed hopper 601 along the running direction of the auger 604 for dehydration.

[0042] A plurality of filter holes 607 are provided at equal intervals on the top of the pad 606, a water guide pipe 608 is inserted and connected to the bottom of the feed hopper 601, and one end of the water guide pipe 608 is inserted and connected to one side of the dehydrator 1, and one end of the rotating shaft 603 passes through the top of the fixed frame 602 and is connected to the second motor 609. During the feeding process, the water in the sludge falls by its own gravity and falls on the pad 606, enters the bottom of the inner wall of the feed hopper 601 through the filter holes 607 on the pad 606, and enters the water collection area below the inner wall of the dehydrator 1 through the water guide pipe 608 for collection, so that the device can achieve the purpose of drainage during the feeding process, and the uninterrupted material guidance of the auger 604 allows the sludge to enter the dehydrator 1 in an orderly and quantitative manner for dehydration operation, without the need for the staff to pay attention all the time and manually introduce the sludge in a quantitative manner, thereby reducing the workload of the staff and improving the dehydration efficiency of the equipment.

A water storage tank 706 is installed at the edge of one side of the top of the dehydrator 1, and one end of the hose 705 is connected to the inner wall of the water storage tank 706. After dehydration is completed, the cleaning nozzle 702 is started, and the cleaning water in the water storage tank 706 is introduced into the water inlet pipe 704 through the hose 705, and then evenly enters the various cleaning nozzles 702 on the inside of the protective cover 701 through each connecting pipe 703, and each cleaning nozzle 702 is tilted toward each squeezing roller and conveyor belt. When the cleaning nozzle 702 sprays water, it can fully spray and rinse the surface of each squeezing roller and conveyor belt, rinse their surface clean, and finally fall into the collection area below the inner wall of the dehydrator 1. There is no need for staff to dismantle the machine and tilt it manually, which improves the convenience of using the device;

[0045] Furthermore, chutes 8 are provided on both sides of the dehydrator 1, and the outer walls of the two ends of the support frame 209 pass through the inner walls of the two chutes 8 and are fixedly connected to the two sides of the second connecting frame 210, and the second connecting frame 210 is placed on the inner side of the second water filtering conveyor belt 203, and a mud guide plate 9 is installed at one end of the inner wall of the dehydrator 1. The inner wall of the dehydrator 1 is located below the second water filtering conveyor belt 203 and is equipped with a first scraper 10, and one side of the first scraper 10 contacts the outer wall of the second water filtering conveyor belt 203. During the dehydration and self-cleaning process, the first water filtering conveyor belt 202 and the second water filtering conveyor belt 203 need to be operated so that the two scrape on the outer walls of the first scraper 10 and the second scraper 11 respectively, and the dirt attached to their surfaces is scraped off to improve the cleaning quality of the equipment. When the second electric push rod 213 pushes the support frame 209, the outer walls of its two ends slide in the two chutes 8 respectively, thereby lifting and lowering the second connecting frame 210.

[0046] A second scraper 11 is installed on the inner wall of the dehydrator 1 below the first water filtering conveyor belt 202, and one side of the second scraper 11 contacts the outer wall of the first water filtering conveyor belt 202. A baffle 12 is installed at the outer edge of the bottom of the inner wall of the dehydrator 1 on one side of the second water filtering conveyor belt 203.
