Description

Technical Field

[0001] This invention relates to an integrated sludge pretreatment machine, belonging to the field of sludge treatment technology. Background Technology

[0002] Sewage sludge, a type of mixed solid waste, accumulates in urban drainage networks, flood control pumping stations, and other sewage ditches and storage sites in the form of a solid-liquid mixture. Currently, the treatment methods for sewage sludge can be broadly categorized into three types: The first type involves establishing centralized sewage sludge treatment plants to separate the sludge into four categories: domestic waste, gravel, sand, and sludge, followed by resource recovery or environmentally friendly disposal of the separated materials. The second type involves using vacuum trucks to collect and transport the sludge, then discharging it to a storage yard for drying and evaporation, followed by mixed landfill disposal. The third type utilizes specialized sanitation vehicles equipped with vacuum purification trucks and vacuum purification trucks to perform on-site suction, dredging, and dewatering of the sludge.

[0003] Of the three technical solutions mentioned above, the first solution requires a large investment and land area, consisting of multiple specialized equipment combinations depending on the sludge treatment process. While it can achieve the recovery and comprehensive treatment of usable resources from sludge from drainage ditches, it relies heavily on collection and vehicle turnover to maintain stable operation of the treatment plant. Furthermore, it carries management risks related to sludge turnover, storage, transportation, and monitoring, making it unsuitable for widespread application in cities with small volumes of sludge from drainage ditches.

[0004] The second option uses vacuum trucks for treatment. Vacuum trucks only have the function of vacuuming, dredging, and transporting sludge. They do not have any mechanized sludge treatment functions or devices. The sludge after vacuuming is mostly treated by natural evaporation and drying through discharge, which is a crude treatment method. It has the defects of secondary pollution and low treatment efficiency, and does not meet the current environmental protection policy requirements for comprehensive sludge treatment.

[0005] The third type involves using specialized sludge treatment vehicles. These sanitation vehicles typically consist of a suction pump, a bar screen, a dosing machine, a mixing tank, and dewatering equipment. While these vehicles offer a degree of integration and mobile suction and dewatering capabilities, they lack the ability to recover usable sand and gravel resources from mixed sludge like that from drainage ditches. Furthermore, because these specialized sludge treatment vehicles use bar screens to intercept and filter solid debris, the screen openings gradually become clogged as the intercepted material accumulates, requiring frequent stops for cleaning. This significantly impacts the continuous operation and overall efficiency of sludge treatment, resulting in long downtime for sludge removal and treatment, prolonged road occupancy, failure to recover usable sludge resources, and low overall treatment efficiency.

[0006] In view of the problems existing in the above three types of equipment in the treatment of sewage sludge in drainage ditches, and based on the requirements of mobile application and the policy of resource-based and environmentally friendly treatment of sludge, we will develop an integrated sludge pretreatment equipment that can continuously input sludge for separation of impurities, sand removal, gravel recovery, sludge collection, auxiliary dosing, and conditioning and mixing. This will help improve the technical level of on-site sewage sludge treatment equipment and special sanitation vehicles, and help improve the overall effect of resource recovery and environmental protection in on-site treatment of sewage sludge in drainage ditches. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated sludge pretreatment machine to solve the problems in the existing sludge treatment process, such as the single function of traditional pretreatment equipment, the lack of devices for further recycling and classification of sludge, the scattered combination of related equipment, the large footprint of the layout, and the restriction on miniaturization and vehicle-mounted applications.

[0008] A mud pretreatment integrated machine includes a four-section mud tank with spring shock-absorbing seats. The mud tank is divided into a first liquid receiving tank, a second buffer tank, a third mixing tank and a fourth liquid level stabilizing tank by a partition. The first liquid receiving tank, the second buffer tank and the third mixing tank are interconnected, and the third mixing tank and the fourth liquid level stabilizing tank are interconnected.

[0009] The first liquid receiving tank is equipped with a shock-absorbing component, and a mud feeding device and a dirt separation and dewatering device are respectively installed on the shock-absorbing component. The dirt separation and dewatering device is used to screen the mud flowing into the mud feeding device.

[0010] The second buffer tank is equipped with a material turning and mixing system. The second buffer tank is connected to the first liquid receiving tank through a backflushing pipe. The material turning and mixing system washes the sediment in the first liquid receiving tank. The third mixing tank is equipped with a mixing and conditioning device on the top of the partition box.

[0011] Furthermore, the mud feeding device includes a U-shaped feeding device support, a connecting pipe is welded on the top of the feeding device support, and a water guide is opened horizontally at the center below the connection between the connecting pipe and the feeding device support. The water guide extends into the connecting pipe, and a water guide groove is welded below the water guide. A bamboo joint is welded to one end of the connecting pipe, and a plug cap is welded to the other end.

[0012] Furthermore, the impurity separation and dewatering device includes an upper screen, a lower screen, and a vibrating motor. The vibrating motor vibrates the slurry filtered by the upper and lower screens and collects it in the first receiving tank.

[0013] Furthermore, the material turning and mixing system includes a material turning pump, a material turning pipe conveying pipe, a flushing pipe, a backflushing valve, a material turning shut-off valve, a siphon mixer, a U-shaped mixing pipe, and a heavy-duty pipe support. The outlet of the material turning pump is connected to the material turning pipe conveying pipe. The material turning pipe conveying pipe is divided into two paths through a T-junction, one path connecting to the siphon mixer and the other path connecting to the backflushing pipe. A material turning shut-off valve is installed on the pipeline of the siphon mixer, and a backflushing valve is installed on the backflushing pipeline of the backflushing pipe. The outlet end of the siphon mixer is connected to the U-shaped mixing pipe, and the outlet of the U-shaped mixing pipe is connected to an elbow pipe section inside the third mixing tank. The U-shaped mixing pipe and the elbow pipe section are welded to the heavy-duty pipe support and fixed to the outside of the third mixing tank by the heavy-duty pipe support.

[0014] Furthermore, the mixing and conditioning device includes a mixer assembly and a mixer support, wherein the mixer support is installed above the third mixing tank and the mixer assembly is installed on the mixer support.

[0015] Furthermore, a mechanical float level sensor is installed inside the fourth liquid level stabilizing tank.

[0016] Furthermore, the mud tank includes a bottom plate, a receiving tank enclosure, a buffer tank enclosure, a mixing tank enclosure, and a level stabilizing tank enclosure; the receiving tank enclosure, the buffer tank enclosure, the mixing tank enclosure, and the level stabilizing tank enclosure are sequentially connected around the bottom plate to form a whole.

[0017] Furthermore, symmetrical support columns are welded to the outer side of the liquid receiving tank enclosure, a connecting beam is welded above the support columns, and a spring damping seat is welded above the connecting beam. The spring damping seat is used to fix the damping components.

[0018] Furthermore, the shock-absorbing component is a shock-absorbing spring.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0020] This invention provides an integrated sludge pretreatment machine for treating sewage sludge in ditches, comprising a four-section sludge tank with spring shock absorbers, a sludge feeding device, a waste separation and dewatering device, a jet anti-settling device, a material turning and mixing system, a stirring and conditioning device, and a liquid level stabilizing device.

[0021] It achieves five comprehensive pretreatment functions during the transportation of sludge-type mud from drainage ditches: continuous waste separation, sand and gravel separation, high-frequency vibration dewatering, mud recycling, auxiliary chemical dosing, and conditioning and mixing.

[0022] After screening and conditioning, the sludge undergoes rapid volume reduction due to the removal of impurities and gravel. Combined with the auxiliary dosing pipe device and U-shaped mixing device in the equipment of this invention, and the stirring and blending effect of the agitator, the sludge after the removal of impurities and gravel is more fully integrated and modified with the chemicals, optimizing the dewatering characteristics of the sludge and making it more conducive to compression dewatering. This facilitates rapid dewatering of the sludge by subsequent filter press dewatering machinery, indirectly improving the overall efficiency and volume reduction dewatering effect of ditch sludge treatment.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1-13 As shown, a mud pretreatment integrated machine is disclosed, including a four-section mud tank 1 with a spring shock absorber seat. The mud tank 1 is divided into a liquid receiving tank G1, a buffer tank G2, a third mixing tank G3 and a fourth liquid level stabilizing tank G4 by a partition. The liquid receiving tank G1, the buffer tank G2 and the third mixing tank G3 are interconnected, and the third mixing tank G3 and the fourth liquid level stabilizing tank G4 are interconnected.

[0039] The liquid receiving tank G1 is equipped with a shock-absorbing component, and the shock-absorbing component is respectively installed with a mud feeding device 3 and a dirt separation and dewatering device 4. The dirt separation and dewatering device 4 is used to screen the mud flowing into the mud feeding device 3.

[0040] The buffer tank G2 is equipped with a material turning and mixing system 6. The buffer tank G2 is connected to the liquid receiving tank G1 through a backflushing pipe 7. The material turning and mixing system 6 is used to rinse the sediment in the liquid receiving tank G1. The third mixing tank G3 is equipped with a mixing and conditioning device 5 on the top of the partition box.

[0041] Four-section mud tank 1, whose interior is divided into four compartments by partitions. The four compartments are welded into a whole in a "field" - shaped layout and are named liquid receiving tank G1, buffer tank G2, stirring tank G3, and liquid level stabilizing tank G4 respectively according to the box shapes formed by each compartment; the liquid receiving tank G1 and the buffer tank G2 are in the two right - hand squares of the "field" layout, with the liquid receiving tank G1 at the bottom and the buffer tank G2 at the top. The stirring tank G3 and the liquid level stabilizing tank G4 are in the two left - hand squares of the "field" layout, with the liquid level stabilizing tank G4 at the bottom and the stirring tank G3 at the top. Among them, the liquid receiving tank G1, the buffer tank G2, and the stirring tank G3 are interconnected, and the stirring tank G3 and the liquid level stabilizing tank G4 are interconnected. The upper parts of all compartment boxes are of open structure without covers.

[0042] Four - section box body, the first compartment is the liquid receiving tank G1. On the outer side of the box body, 4 columns are symmetrically welded at a certain interval. Above the columns, a connecting cross - beam 1 - 105 is welded. Above the connecting cross - beam 1 - 105, a spring shock absorber seat 1 - 106 is welded. A mud feeding device 3 and a miscellaneous pollution separation and dehydration device 4 are respectively installed on the connecting cross - beam 1 - 105.

[0043] The mud feeding device 3 straddles above the miscellaneous pollution separation and dehydration device 4 and is fixed to the connecting cross - beam 1 - 105 on the first compartment liquid receiving tank G1. There is no rigid assembly connection between the mud feeding device 3 and the miscellaneous pollution separation and dehydration device 4. The mud feeding device 3 is a "door" - shaped feeding device support welded by channel steels. Above the support, a guiding pipe 3 - 3 is welded. At the middle position of the pipe body of the guiding pipe below the combination of the support and the guiding pipe, a rectangular water guiding port is transversely opened and penetrates into the guiding pipe. A water guiding groove 3 - 4 is welded to the water guiding port and extends outward perpendicular to the "door" - shaped column. At both ends of the guiding pipe 3 - 3, one end is welded with a bamboo - joint pipe joint 3 - 1, which can be fixed to connect the mud conveying water belt and the sewage suction pump through a pipe clamp. The other end is welded and blocked by a plug cap 3 - 5. After the mud enters the guiding pipe, its water head impact force is counteracted by the blockage of the plug cap, and the mud then flows out from the water guiding groove opened on the pipe body and flows into the upper - layer sieve plate of the miscellaneous pollution separation and dehydration device 4. A water - blocking rubber cover plate is installed above the vibrating screen body. The rubber cover plate is opened at the place where the water guiding groove is inserted. Inside the access hole of the water guiding groove, it can prevent mud splashing when feeding the mud and impacting the sieve plate. The columns of the mud feeding device 3 are installed above the connecting cross - beams on both sides of the liquid receiving tank G1 and are fixed by bolts.

[0044] The miscellaneous pollution separation and dehydration device 4 is installed above the shock - absorbing spring 12. The shock - absorbing spring 12 is installed on the spring shock absorber seat 1 - 106 on the connecting cross - beam of the liquid receiving tank and is connected and fixed by a fiber expansion leather and a pressing plate through bolts. Thus, it ensures the safety of the vibrating screen during the screening vibration operation.

[0045] The impurity separation and dewatering device 4 has a double-layer structure, which can separate materials into three categories according to particle size. When the slurry is conveyed into the slurry feeding device 3 by external power, it is guided and flushed by the slurry feeding device 3 and falls into the upper screen 4-1 of the vibrating screen. The upper screen separates impurities and garbage larger than 5mm, while the lower screen 4-2 separates gravel and sand between 2 and 5mm, realizing the recovery of usable resources. The material on the screen surfaces of the two screens is dewatered and discharged by the high-frequency vibration of the vibrating motor 4-3. The slurry filtered through the two screens enters the receiving tank G1 for collection.

[0046] The sludge enters the impurity separation and dewatering device 4 and is screened and filtered in the following order: from top to bottom, first passing through the upper screen 4-1, then through the lower screen 4-2, and finally entering the receiving tank G1 for collection.

[0047] The buffer tank G2 compartment is equipped with a material-turning pump 6-1. The outlet of the material-turning pump 6-1 is connected to the material-turning conveying pipe 6-2. The material-turning conveying pipe 6-2 is divided into two paths by a three-way pipe joint. One path is connected to the siphon mixer 6-6, and the other path is connected to the backflushing pipe 7 in the receiving tank G1. Each of the two pipes is equipped with a shut-off valve. Under normal conditions, the material-turning shut-off valve 6-5 installed on the siphon mixer pipe is in the normally open state, and the backflushing valve 6-41 on the backflushing pipe is in the closed state. When mud sedimentation occurs in the receiving tank G1, opening the backflushing valve 6-4 on the backflushing pipe can flush the sediment in the receiving tank G1, agitate the mud in the tank, and prevent sedimentation and accumulation.

[0048] The siphon mixer 6-6 has a venturi structure with a dosing port located at the middle half of its tube. When slurry flows into this pipe, a negative pressure is generated, automatically siphoning the chemical and mixing it with the slurry jet inside the pipe. The outlet of the siphon mixer 6-6 is connected to a U-shaped mixing pipe 6-7. The outlet of the U-shaped mixing pipe 6-7 is connected to an elbow pipe section 13 that extends into the third-section mixing tank G3. The U-shaped mixing pipe 6-7 and the elbow pipe section 13 are fixed to the outside of the mixing tank G3 by a heavy-duty pipe bracket 15 welded to the outside of the tank. Connections between pipes and between pipes and valves are made through flanges.

[0049] The slurry is pressurized and transported by the feed pump 6-1 to form a high-pressure jet. The siphon effect of the siphon mixer 6-6 is used to achieve self-priming dosing fluid mixing. The mixing stroke and time are extended through the U-shaped mixing pipe 6-7 to enhance the pipeline mixing effect.

[0050] After the mixed sludge enters the mixing tank G3, to further increase the mixing volume, a tank support frame 1-109 is welded above the opening of the G3 section. This frame is custom-made according to the size and shape of the G3 section and welded to the top of the G3 section, serving to strengthen the connection rigidity of the tank and support the installation of the mixer. An agitator support 5-2 is installed above the G3 section, and an agitator assembly 5-1 is installed above the agitator support. The agitator assembly 5-1 mixes and conditions the chemicals with the sludge, producing flocculation and other effects that facilitate efficient dewatering in subsequent dewatering equipment, thus improving the overall treatment efficiency of the sludge treatment system.

[0051] The liquid level stabilization tank G4 is equipped with a mechanical float liquid level sensor 2, which is used to detect the liquid level in the tank. When the mud level in the tank exceeds the set safe height, the external dredging pump can be controlled to stop transporting mud through the mechanical liquid level sensor 2 to prevent overflow.

[0052] The aforementioned equipment uses a four-section mud tank 1 with spring shock absorbers as an integrated platform, realizing six integrated treatment functions for sludge in drainage ditches: separation of impurities, classification and dewatering, volume reduction pretreatment, transfer and chemical dosing, mixing and conditioning, and system balancing. It effectively promotes the efficiency of classification, dewatering, and high-efficiency volume reduction in the on-site treatment of sludge in drainage ditches. Through integrated functions, it completes the chemical dosing and conditioning modification of the separated mud, which optimizes the mud compression and dewatering performance and improves the mud dewatering performance for subsequent mud dewatering, pressure reduction, and dry discharge.

[0053] The four-section mud tank with spring damping seats includes a bottom plate 1-5, a receiving tank enclosure 1-1, a buffer tank enclosure 1-2, a mixing tank enclosure 1-3, and a level stabilizing tank enclosure 1-4. Based on the shape of the bottom plate 1-5, the receiving tank enclosure 1-1, the buffer tank enclosure 1-2, the mixing tank enclosure 1-3, and the level stabilizing tank enclosure 1-4 are sequentially welded together around the shape of the bottom plate to form a whole. The mixing tank enclosure 1-3 is a cylindrical shell formed by bending rectangular and semi-circular sections. Its outer shell is welded to the bent end faces of the receiving tank enclosure 1-1, the buffer tank enclosure 1-2, and the level stabilizing tank enclosure 1-4, and it communicates with the receiving tank enclosure 1-1 and the level stabilizing tank enclosure 1-4 within their respective enclosure sections. The receiving tank enclosure 1-1 and the buffer tank enclosure 1-2 are also interconnected.

[0054] Four support columns 1-101 are symmetrically welded to the outer side of the liquid receiving tank enclosure 1-1. The upper end face of the support columns is flush with the upper end face of the enclosure. A connecting beam 1-105 is welded above the end face to connect the support columns in pairs into a whole. Four shock absorber seats 1-106 are welded to the center line of the support columns corresponding to the lower part of the connecting beam. The four shock absorber seats can be connected to the vibrating screen by inserting shock absorber springs. After the vibrating screen is connected to the shock absorber seats 1-106 by inserting shock absorber springs, the shock absorber seats and the vibrating screen base can be connected and fixed by telescopic limit skins and pressure plates to ensure the safety of the vibrating screen during screen vibration.

[0055] The mud backflushing pipe 1-107 is arranged in a 3 / 4 circle around the inner wall of the receiving tank G1. The inlet of the backflushing pipe is welded to the enclosure shared with the buffer tank G2. The spray direction of the backflushing pipe outlet is aimed at the four corners of the tank and the positions where sedimentation is more likely to occur. The slurry stirring and anti-settling effect generated by the spraying is beneficial to the efficient suction and transportation of the material turning pump 6-1 in the buffer tank G2. The material turning pump mounting bracket 1-108 is welded in the center of the top plane of the buffer tank G2, and the material turning pump 6-1 is fixed on the mounting bracket.

[0056] The box support frame 1-109 is custom-made and welded to the top of the mixing box G3 according to its internal dimensions and shape, flush with the upper surface of the box. It serves to support both the box and the mixer.

[0057] The level gauge mounting bracket 1-104 is welded to the top of the level stabilizing tank G4, flush with the top surface of the tank. The mounting bracket is made of a bent plate, with a central opening for mounting a mechanical float sensor. Flange holes are opened around the central opening for fixing the sensor mounting base.

[0058] The slurry discharge pipe 1-103 is welded to the bottom plate 1-5 on the right side of the liquid level stabilization tank G4 and connects with the stabilization tank G4 to realize the external output of the sludge after classification, separation, flocculation and conditioning.

[0059] Connecting plates 1-102, a total of 4, are distributed around the perimeter of the housing according to the overall fixing requirements of the machine. They are welded to the adjacent housing shells. The connecting plates serve to connect and fix the machine to the carrier platform and can be used for modification and installation on mobile platforms or special vehicles. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
