Description

Technical Field

[0001] This utility model relates to the technical field of sewage suction and purification vehicles, specifically a mobile sewage suction and purification vehicle. Background Technology

[0002] As is well known, there are many types of mobile vacuum and purification vehicles, including small mobile vacuum and purification vehicles that are pushed by manpower. These devices are usually compact in design and small in size, and have basic vacuuming and purification functions. They are suitable for places with narrow spaces or high requirements for equipment mobility, such as small basements, narrow passages in residential areas, and local sewage cleaning in small catering establishments.

[0003] Existing mobile sewage suction and purification vehicles typically have their sedimentation tanks and filter boxes fixed to the base, making disassembly difficult. During long-term use, these components will wear down due to frequent contact with sewage and impurities. Once wear occurs and replacement is needed, the fixed connection to the base makes the operation extremely inconvenient and difficult to complete quickly. This not only prolongs the equipment maintenance cycle and increases maintenance costs, but may also affect the sewage cleaning work in the relevant places due to the equipment being unable to work normally for a long time, thus hindering the entire sewage suction and purification operation process and reducing the efficiency and practicality 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 mobile sewage suction and purification vehicle.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile sewage suction and purification vehicle, comprising a base plate, a pulley mechanism, a sedimentation tank, a filter tank, a cover plate, and a connecting mechanism. The pulley mechanism is located at the bottom of the base plate, and there are several pulley mechanisms. A push handle is provided on one side of the base plate. The sedimentation tank is placed on the top of the base plate, and the top of the sedimentation tank is connected to one end of a positioning block. The other end of the positioning block passes through the base plate. A sewage discharge component is provided at the bottom front of the sedimentation tank. The filter tank is connected to the base plate through the connecting mechanism. The cover plate is connected to the filter tank through a first bolt. A material suction component is provided on the cover plate. A material discharge component is provided at the bottom of the filter tank. The connecting mechanism includes a telescopic cylinder, a connecting block, a fixing block, and a second bolt. One end of the telescopic cylinder is connected to the top of the base plate, and the other end of the telescopic cylinder is connected to one end of the connecting block. One end of the fixing block is located on the side of the filter tank, and the fixing block contacts the connecting block. The fixing block and the connecting block are connected by the second bolt. There are two connecting mechanisms.

[0008] To improve stability, the present invention is improved in that the connecting mechanism includes a guide post and a guide block. The guide post is disposed on the top of the base plate, and the guide block is connected to the side of the filter box. The guide block is sleeved on the outside of the guide post.

[0009] To improve stability, this utility model is improved by symmetrically arranging the two connecting mechanisms.

[0010] To improve stability, this utility model is improved by having several pulley mechanisms arranged symmetrically.

[0011] To facilitate observation of the interior of the sedimentation tank and the filter tank, this utility model is improved by providing observation windows on the front of both the sedimentation tank and the filter tank.

[0012] To improve the connection effect, the present invention is improved by welding the push handle to the base plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a mobile sewage suction and purification vehicle, which has the following features:

[0015] Beneficial effects:

[0016] This mobile sewage suction and purification vehicle is designed with the ease of maintenance in mind. Both the sedimentation tank and the filter tank are designed to be detachably connected to the base plate. During long-term use, the sedimentation tank and the filter tank will inevitably wear out due to frequent contact with sewage and impurities. If such a situation occurs and replacement is needed, the operator can quickly disassemble the sedimentation tank and the filter tank by simply controlling the connection mechanism.

[0017] Unlike traditional fixed connections, where filter boxes and sedimentation tanks are tightly connected to the base plate, making disassembly extremely difficult, and when they wear out, the inconvenience of disassembly often prevents timely replacement, increasing maintenance costs and seriously affecting the subsequent normal operation of the equipment. This structure effectively avoids these problems. Through a convenient disassembly design, worn parts can be quickly replaced, reducing equipment downtime, ensuring continuous and efficient operation, greatly improving the practicality and service life of the equipment, and providing users with a more reliable user experience.

[0023] 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.

[0024] Please see Figure 1-4 A mobile sewage suction and purification vehicle includes a base plate 1, a pulley mechanism 2, a sedimentation tank 4, a filter tank 7, a cover plate 9, and a connecting mechanism 12. The pulley mechanism 2 is located at the bottom of the base plate 1, and several pulley mechanisms 2 are provided. A push handle 3 is provided on one side of the base plate 1. The sedimentation tank 4 is placed on top of the base plate 1, and one end of the top of the sedimentation tank 4 is connected to a positioning block 5. The other end of the positioning block 5 passes through the base plate 1. A sewage discharge assembly 6 is provided at the bottom front of the sedimentation tank 4. The filter tank 7 is connected to the base plate 1 via the connecting mechanism 12. The cover plate 9 is connected to the base plate 1 via a first bolt 10. The filter box 7 is connected to the cover plate 9, which is equipped with a material extraction component 11. The bottom of the filter box 7 is equipped with a material discharge component 8. The connecting mechanism 12 includes a telescopic cylinder 13, a connecting block 14, a fixing block 15, and a second bolt 16. One end of the telescopic cylinder 13 is connected to the top of the base plate 1, and the other end is connected to one end of the connecting block 14. One end of the fixing block 15 is located on the side of the filter box 7, and the fixing block 15 contacts the connecting block 14. The fixing block 15 and the connecting block 14 are connected by the second bolt 16. Two connecting mechanisms 12 are provided.

[0025] Working principle: such as Figure 1As shown, the staff can easily move the entire equipment to a suitable position by holding the push handle 3 and using the pulley mechanism 2 at the bottom of the base plate 1. The pulley mechanism 2 uses common casters on the market, and the foot brake assembly equipped on it can effectively fix the pulley after the equipment reaches the designated position, ensuring that the equipment remains stable during operation. After the equipment is in place, the power cord is connected to the external mains socket to power the equipment (the length of the power cord is reasonably designed to meet the actual use needs, and the specific details are not described here).

[0026] After the equipment is powered on, the staff activates the telescopic cylinder 13 to drive the filter box 7 to descend until the filter box 7 is in close contact with the top of the sedimentation box 4, completely covering the top of the sedimentation box and forming a closed sewage purification space. Then, the staff inserts the suction component 11 into the designated position of the sewage to be treated, and the sewage suction and purification work can be started. The suction component 11 is mainly composed of a pump body, a folded hose and a discharge pipe (its specific structure is not described in detail here). Under the suction of the pump body, the sewage is pumped into the filter box 7 through the folded hose and the discharge pipe.

[0027] The pump body of the material extraction assembly 11 is a centrifugal pump. The centrifugal pump uses a high-speed rotating impeller to throw the liquid inside the pump to the outside under the action of centrifugal force, thereby creating a vacuum at the center of the impeller, continuously drawing sewage into the pump and discharging it through the outlet pipe. Its advantages are large flow rate and high efficiency, which can quickly extract large amounts of sewage and adapt to the needs of sewage suction operations of different scales. The folding hose is made of acid and alkali resistant rubber material. This material gives it good corrosion resistance and can effectively resist the erosion of acid and alkali substances in sewage, extending the service life of the hose. At the same time, the folding hose has the characteristics of being foldable and wear-resistant. The foldable design makes it convenient for equipment storage and carrying, reducing the space occupied; the wear-resistant characteristics ensure that the hose is not easily damaged during frequent bending and use, ensuring the sealing and stability of the sewage transportation process, effectively avoiding sewage leakage, and improving the overall working performance of the material extraction assembly 11.

[0028] The filter box 7 adopts conventional filtration technology on the market. It has a filter screen connected by bolts inside. After the sewage enters the filter box 7, the filter screen plays its role and effectively filters out large particles and other impurities. The sewage after preliminary filtration flows into the sedimentation box 4 through the discharge component 8. In the sedimentation box 4, the remaining impurities in the sewage gradually sink under the action of gravity and finally settle to the bottom of the sedimentation box 4, realizing further separation of sewage and impurities.

[0029] Depending on the specific application, different materials can be selected for the filter screen inside filter box 7. Stainless steel filter screens are suitable for treating wastewater containing a large amount of metallic impurities or requiring high corrosion resistance. Stainless steel filter screens have excellent corrosion resistance and high strength, effectively filtering metal particles, sand, and other impurities from wastewater. They are also resistant to deformation and damage, and have a long service life. If the wastewater mainly contains fine organic impurities or requires extremely high filtration precision, nylon filter screens are more suitable. Nylon filter screens have uniform pore size and a filtration precision down to the micron level, effectively intercepting extremely small particles in wastewater. In terms of filtration precision, stainless steel filter screens can generally filter out particles larger than 0.1 mm in diameter. For larger particles... The stainless steel filter screen has a significant particle interception effect, which can effectively prevent large particles from entering the subsequent treatment process and protect other equipment. The nylon filter screen has a finer filtration precision, which can filter out particles with a diameter as small as 5 micrometers. It can deeply remove fine impurities in sewage, making the purified water clearer. In terms of applicable sewage types, the stainless steel filter screen is suitable for industrial wastewater, construction site sewage and other sewage containing more solid particles and metal debris. These sewages contain impurities with high hardness and strong corrosiveness. The characteristics of the stainless steel filter screen can meet the filtration requirements. The nylon filter screen is more suitable for catering wastewater, domestic sewage and other sewage containing more organic impurities and suspended solids. It can effectively remove fine particles in sewage, ensure sewage purification effect, and make it meet discharge standards or reuse standards.

[0030] After the wastewater purification treatment is completed, the equipment should be restored to its original state. Figure 1 In the initial state shown, the purified wastewater in the sedimentation tank 4 is then pumped out and discharged using the external pumping assembly, while the precipitated impurities remain in the sedimentation tank 4. Finally, the drain assembly 6 at the bottom front of the sedimentation tank 4 is opened to discharge the precipitated impurities from the equipment.

[0031] When it is necessary to clean the inside of the filter box 7, since the cover plate 9 is connected to the filter box 7 by the first bolt 10, the staff can use an external screwdriver to unscrew the first bolt 10 to separate the cover plate 9 from the filter box 7, so that the opening at the top of the filter box 7 is exposed. Then, use external flushing equipment and other cleaning tools to thoroughly clean the filter box 7 (the specific type of cleaning equipment can be selected according to actual needs, and no specific restrictions are made here).

[0032] If filter box 7 and sedimentation box 4 show signs of wear and tear due to prolonged use and need to be replaced, the operating steps are as follows: Figure 1As shown, the workers first use an external screwdriver to loosen the second bolt 16 to separate it from the fixing block 15 and the connecting block 14. Then, two workers work together to lift the filter box 7 and remove it. Next, the workers lift the sedimentation box 4 upwards to separate the positioning block 5 at the bottom of the sedimentation box 4 from the base plate 1, thus successfully separating the sedimentation box 4 from the base plate 1. The new parts can be purchased from the manufacturer (details of the purchase of new parts are not described here). Before replacing the filter box 7 and the sedimentation box 4, it is essential to ensure that there is no residual liquid inside them to ensure a smooth replacement process.

[0033] The telescopic cylinder 13 mentioned in the article is a conventional electrically driven cylinder on the market. It mainly consists of a cylinder barrel, piston, piston rod, seals, and electrical control system. Through electric drive, the telescopic movement of the cylinder can be precisely controlled, thereby stably driving the filter box to rise and fall. Its electrical control system can flexibly adjust the telescopic speed and stroke to meet the needs of the equipment under different working conditions and ensure the high efficiency and stability of the equipment operation.

[0034] In this embodiment, the design of the connecting mechanism 12 fully considers the stability of the filter box 7 during lifting and lowering. The connecting mechanism 12 includes a guide post 18 and a guide block 17. The guide post 18 is stably set on the top of the base plate 1, while the guide block 17 is tightly connected to the side of the filter box 7. The guide block 17 fits exactly outside the guide post 18. When the telescopic cylinder 13 is started and drives the filter box 7 to lift and lower, the guide block 17 will slide smoothly along the guide post 18. This design can effectively limit the movement trajectory of the filter box 7 and avoid unstable situations such as shaking and deviation during lifting and lowering, providing a solid guarantee for the stable operation of the filter box 7 and ensuring that the overall purification work of the equipment is carried out efficiently and reliably.

[0035] In this embodiment, to further improve the stability of the equipment, the two connecting mechanisms 12 are symmetrically arranged. This symmetrical layout ensures that the filter box 7 is subjected to uniform force on both sides during installation and operation. During the process of the telescopic cylinder 13 driving the filter box 7 to rise and fall, the symmetrical connecting mechanisms can balance the forces in all directions, effectively reducing the shaking and tilting of the equipment, and providing more reliable structural support for the entire sewage suction and purification work.

[0036] In this embodiment, to enhance the overall stability of the equipment, the layout of the pulley mechanism 2 is carefully designed. Several pulley mechanisms 2 are symmetrically arranged at the bottom of the base plate 1. The symmetrically distributed pulley mechanism can evenly distribute the gravity on the equipment during movement, avoiding tilting due to uneven force. Whether pushing the equipment forward, turning, or placing it at rest, it can ensure the stability of the equipment, reduce the risk of tipping over, and improve operational safety.

[0037] In this embodiment, to facilitate staff to understand the working status inside the sedimentation tank 4 and the filter tank 7 at any time, observation windows are specially provided on the front of both the sedimentation tank 4 and the filter tank 7. The design of the observation windows allows staff to directly observe the internal sewage sedimentation, impurity filtration, and other conditions without disassembling the equipment, so as to promptly detect abnormal problems such as blockages and overflows, and then quickly take corresponding measures to ensure the stable operation and purification effect of the equipment.

[0038] In this embodiment, in order to effectively improve the connection reliability between the push handle 3 and the base plate 1, welding is used for fixing. Welding can make the push handle 3 and the base plate 1 tightly integrated into a whole. Compared with other connection methods, the welded connection has higher strength and stronger stability. In daily use, it can effectively avoid the push handle from affecting the pushing of the equipment, provide the operator with a stable grip point, and ensure the safety and convenience of the equipment movement operation.

[0039] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
