Description

Technical Field

[0001] This utility model belongs to the field of liquid recovery device technology, and in particular relates to an on-site contaminated liquid recovery device for emergency rescue of chemical accidents. Background Technology

[0002] Chemical accident emergency rescue field contaminated liquid recovery devices are key equipment for dealing with chemical leaks, hazardous chemical transportation accidents, and other similar scenarios. They are primarily used to quickly recover leaked acidic, alkaline, and organic solvent-based contaminated liquids, preventing them from seeping into soil or flowing into water bodies and causing secondary pollution. The equipment is typically equipped with a corrosion-resistant collection chamber, a high-efficiency negative pressure suction system, and a preliminary filtration module. It rapidly adsorbs contaminated liquids using negative pressure suction, filters out some impurities, and temporarily stores the liquid in a sealed chamber. Its lightweight and portable design makes it suitable for mobile field operations, and the use of chemically corrosion-resistant materials makes it compatible with various types of contaminants. Its simple operation helps rescue personnel control the spread of pollution in a short time, buying crucial time for subsequent harmless treatment.

[0003] According to a public disclosure (Publication No.: CN202300273U), a liquid recovery device includes: a lifting hook installed at the top of the main body shell; an oil pipe body sealing block and an oil pipe coupling sealing block respectively locked and fixed at the upper and lower ends of the main body shell through sealing block locking holes; a valve locking handle and a valve opening and closing shaft installed on the valve; the shaft portion of the main body shell is sealed by side sealing rubber parts; the valve is sealed by valve sealing rubber parts when closed; and a drain hole is opened at the lower end of the main body shell, which is connected to a drain pipe. This utility model realizes the unified and effective recovery of liquid in the oil pipe, avoiding environmental pollution. It overcomes the shortcomings of existing operations where the discharge and recovery of liquid in the oil pipe cannot be effectively controlled, causing environmental pollution.

[0004] The aforementioned application utilizes the cooperation of simple container suction devices and drain pipes to achieve unified and effective recovery of liquid in oil pipes. However, the liquid suction effect is poor and blockage is likely to occur. Therefore, we propose an on-site contaminated liquid recovery device for chemical accident emergency rescue. Utility Model Content

[0005] The purpose of this invention is to provide an on-site contaminated liquid recovery device for emergency rescue in chemical accidents. Through the design of components such as an anti-clogging liquid suction mechanism and a wall scraping and cleaning mechanism, it solves the problems of poor liquid suction effect and easy clogging in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a field contaminated liquid recovery device for emergency rescue of chemical accidents, comprising: a vehicle platform, a support fixedly connected to the bottom of the vehicle platform, wheels rotatably connected to the side of the support, a column fixedly connected to the top of the vehicle platform, a handle fixedly connected to the side of the column, and an anti-clogging liquid suction mechanism provided on the top of the vehicle platform. The anti-clogging liquid suction mechanism includes a motor, the bottom of which is fixedly connected to the top of the vehicle platform. A rotating shaft is fixedly connected to the end of the motor's output shaft. A housing is fixedly connected to the top of the vehicle platform. A pump body is fixedly connected to the inner side of the housing. A pump cover is bolted to the side of the pump body. A rotor is fixedly connected to the circumferential surface of the rotating shaft. Blades are slidably connected to the inner side of the rotor. A pipe is bolted to the top of the pump body's outlet. A collection box is fixedly connected to one end of the pipe. A cover is fitted onto the top of the collection box. A connecting pipe is fixedly connected to the side of the housing. A filter screen is snapped onto the inner side of the connecting pipe. A handle is fixedly connected to the top of the filter screen.

[0007] Furthermore, the sides of the pump cover and the pipe are bolted with screws. Several screws are arranged in a circumferential array on the sides of the pump cover and the pipe to achieve a stable fixation. This ensures the reliability of the connection between the pump cover and the pump body, and between the pipe and the pump body outlet. It also prevents components from loosening due to vibration or pressure during liquid transportation, shortens operation time during emergency maintenance, and does not affect the efficiency of contaminated liquid recovery.

[0008] Furthermore, the pump body has an eccentric hole inside, and the tip of the blade can form a dynamic sealing cavity with the inner wall of the eccentric hole. As the rotor rotates, the volume of the sealing cavity will change periodically due to the eccentric design, realizing the core principle of efficient liquid suction and discharge. The rotation radius of the blade is smaller than the inner wall size of the eccentric hole, avoiding direct rigid contact between the blade and the hole wall to prevent wear, ensuring continuous and uninterrupted liquid suction, and improving the anti-clogging effect.

[0009] Furthermore, the rotor has slots on its circumferential surface, and the number of slots and blades is set to several, and they are arranged in a circumferential array on the circumferential surface of the rotor to serve as a container and guide, ensuring that the blades can slide flexibly in the radial direction to fit the inner wall of the eccentric hole, ensuring the effective formation of the sealing cavity, improving the continuity and uniformity of the suction and discharge liquid, and avoiding flow fluctuations caused by the single blade design.

[0010] Furthermore, a wall-scraping cleaning mechanism is provided on the top of the vehicle panel. The wall-scraping cleaning mechanism includes a bevel gear one, the side of which is fixedly connected to the end of the rotating shaft away from the motor. A rotating rod is rotatably connected to the inner side of the vehicle panel. A bevel gear two is fixedly connected to one end of the rotating rod. The bevel gear one and bevel gear two mesh with each other. A pulley one is fixedly connected to the other end of the rotating rod. A pulley two is rotatably connected to the bottom of the vehicle panel. A belt is provided on the circumferential surface of the pulley one. The pulley one is connected to the pulley two through the belt. A connecting rod is fixedly connected to the top of the pulley two. A scraper is fixedly connected to the circumferential surface of the connecting rod.

[0011] Furthermore, the scraper has a beveled surface on its side, and the inner wall of the collection box is located on the displacement trajectory of the scraper's beveled surface. This reduces the frictional resistance between the scraper and the inner wall of the collection box, prevents rotational jamming, efficiently peels off the attached viscous contaminants, and avoids the accumulation of contaminants on the box wall, which could lead to a reduction in the collection space or blockage of the drain outlet.

[0012] Furthermore, the number of wheels is set to several and they are symmetrically arranged along the vertical central axis of the vehicle platform to ensure stability during movement and prevent tipping, facilitating quick handling of the device. The rotation radius of the scraper is smaller than the radius of the inner wall of the collection box, which can avoid rigid collision with the box wall during rotation and damage to the components. At the same time, its beveled design can still ensure that it fits the inner wall effectively to scrape away pollutants, protecting the equipment structure and maintaining the cleaning effect to ensure sufficient collection box volume.

[0013] This utility model has the following beneficial effects: This invention achieves efficient liquid suction through the coordinated operation of components such as the pump body, rotor, and blades within the anti-clogging suction mechanism. Compared to traditional centrifugal pumps, it reduces the risk of solid particle blockage and is more suitable for contaminated liquids containing suspended solids. The pre-mounted detachable filter screen can intercept large particulate impurities, effectively protecting the core components of the pump body. The handle on top of the filter screen facilitates quick replacement, and its material can be selected according to the characteristics of the contaminated medium to adapt to different corrosive environments. At the same time, the pump cover and pipeline are connected by a circumferential array of screws, which facilitates quick disassembly and maintenance, shortens troubleshooting time in emergencies, and ensures the continuity and efficiency of contaminated liquid recovery.

[0014] This invention utilizes the coordinated operation of components such as belts, scrapers, and bevel gears within the wall-scraping cleaning mechanism. It eliminates the need for an additional power source, saving equipment costs and space. The beveled side of the scraper conforms to the inner wall of the collection box, effectively scraping away adhered viscous contaminants and preventing impurities from accumulating and clogging the collection box, ensuring sufficient collection space. Simultaneously, the scraper's rotation radius is smaller than the inner wall radius of the collection box, preventing mechanical collisions that could damage components. Furthermore, the fully automated cleaning process requires no manual operation, improving emergency recovery efficiency and reducing the risk of personnel exposure to harmful contaminants.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] A chemical accident emergency rescue on-site contaminated liquid recovery device includes: a platform 1, a support 2 fixedly connected to the bottom of the platform 1, wheels 3 rotatably connected to the side of the support 2, a column 4 fixedly connected to the top of the platform 1, a handle 5 fixedly connected to the side of the column 4, and an anti-clogging liquid suction mechanism 6 provided on the top of the platform 1.

[0019] The anti-clogging liquid suction mechanism 6 includes a motor 61, the bottom of which is fixedly connected to the top of the vehicle plate 1. A rotating shaft 62 is fixedly connected to the end of the output shaft of the motor 61. A housing 63 is fixedly connected to the top of the vehicle plate 1. A pump body 64 is fixedly connected to the inner side of the housing 63. A pump cover 65 is bolted to the side of the pump body 64. A rotor 66 is fixedly connected to the circumferential surface of the rotating shaft 62. A blade 67 is slidably connected to the inner side of the rotor 66. A pipe 68 is bolted to the top of the outlet of the pump body 64. A collection box 69 is fixedly connected to one end of the pipe 68. A cover 610 is fitted onto the top of the collection box 69. A connecting pipe 611 is fixedly connected to the side of the housing 63. A filter screen 612 is snapped onto the inner side of the connecting pipe 611. A handle 613 is fixedly connected to the top of the filter screen 612.

[0020] As shown in the figure, screws 614 are bolted to the sides of the pump cover 65 and the pipe 68. Several screws 614 are arranged in a circumferential array on the sides of the pump cover 65 and the pipe 68 to achieve a stable fixation. This ensures the reliability of the connection between the pump cover 65 and the pump body 64, and between the pipe 68 and the outlet of the pump body 64. It also prevents the components from loosening due to vibration or pressure during liquid transportation, shortens the operation time during emergency maintenance, and does not affect the efficiency of contaminated liquid recovery.

[0021] As shown in the figure, the pump body 64 has an eccentric hole inside. The tip of the blade 67 can form a dynamic sealing cavity with the inner wall of the eccentric hole. As the rotor 66 rotates, the volume of the sealing cavity will change periodically due to the eccentric design, realizing the core principle of efficient liquid suction and discharge. The rotation radius of the blade 67 is smaller than the inner wall size of the eccentric hole, avoiding direct rigid contact between the blade 67 and the hole wall, which would cause wear. This ensures that the liquid suction process is continuous and uninterrupted, and improves the anti-clogging effect.

[0022] As shown in the figure, the circumferential surface of the rotor 66 is provided with slots, and the number of slots and blades 67 is set to several, and they are arranged in a circumferential array on the circumferential surface of the rotor 66 to play a role in receiving and guiding, ensuring that the blades 67 can slide flexibly in the radial direction to fit the inner wall of the eccentric hole, ensuring the effective formation of the sealing cavity, improving the continuity and uniformity of suction and discharge liquid, and avoiding flow fluctuations caused by the design of a single blade 67.

[0023] As shown in the figure, a wall-scraping cleaning mechanism 7 is provided on the top of the vehicle plate 1. The wall-scraping cleaning mechanism 7 includes a bevel gear 71. The side of the bevel gear 71 is fixedly connected to the end of the rotating shaft 62 away from the motor 61. A rotating rod 72 is rotatably connected to the inner side of the vehicle plate 1. A bevel gear 73 is fixedly connected to one end of the rotating rod 72. The bevel gear 71 and the bevel gear 73 mesh with each other. A pulley 74 is fixedly connected to the other end of the rotating rod 72. A pulley 75 is rotatably connected to the bottom of the vehicle plate 1. A belt 76 is provided on the circumferential surface of the pulley 74. The pulley 74 is connected to the pulley 75 through the belt 76. A connecting rod 77 is fixedly connected to the top of the pulley 75. A scraper 78 is fixedly connected to the circumferential surface of the connecting rod 77.

[0024] As shown in the figure, the scraper 78 has a beveled surface on its side. The inner wall of the collection box 69 is located on the displacement trajectory of the beveled surface of the scraper 78, which reduces the frictional resistance between the scraper 78 and the inner wall of the collection box 69, avoids rotation jamming, efficiently peels off the attached viscous contaminants, and prevents contaminants from accumulating on the box wall, which would cause the collection space to shrink or block the drain port.

[0025] As shown in the figure, there are several wheels 3, which are symmetrical about each other along the vertical centerline of the vehicle plate 1 to ensure stability during movement and prevent tipping. This facilitates quick handling of the device. The rotation radius of the scraper 78 is smaller than the inner wall radius of the collection box 69, which can avoid rigid collision with the box wall during rotation and damage to the parts. At the same time, its beveled design can still ensure that it fits the inner wall effectively to scrape away pollutants, thus protecting the equipment structure and maintaining the cleaning effect to ensure that the collection box 69 has sufficient volume.

[0026] One specific application of this embodiment is: When the anti-clogging suction mechanism 6 is working, the operator first starts the motor 61, whose output shaft drives the rotating shaft 62 to rotate. The rotating shaft 62 further drives the rotor 66 on the circumferential surface to rotate synchronously. The blades 67 in the slots on the circumferential surface of the rotor 66 rotate with the rotor 66. Because the pump body 64 has an eccentric hole inside and the rotation radius of the blades 67 is smaller than the inner wall size of the eccentric hole, the blades 67 will slide radially along the slots of the rotor 66 and always fit against the inner wall of the eccentric hole of the pump body 64, thus forming multiple periodically changing sealed cavities within the pump body 64. When the volume of the sealed cavity increases, a negative pressure is generated, which draws in the contaminated liquid through the connecting pipe 611. When the liquid flows through the filter screen 612 that is snapped onto the inner side of the connecting pipe 611, the filter screen 612 intercepts large particles of impurities to prevent them from entering the pump body 64 and causing blockage. Subsequently, the filtered liquid enters the sealed cavity. When the volume of the sealed cavity decreases, the liquid is pressurized and transported through the pipe 68 bolted to the top of the outlet of the pump body 64. Finally, it enters the collection box 69 fixedly connected to one end of the pipe 68 to complete the recycling. If it is necessary to clean the filter screen 612, it can be removed from the pipe 611 by the handle 613 fixedly connected to the top of the filter screen 612. The pump cover 65 is bolted to the pump body 64 by screws 614 and can be disassembled and opened to open the pump body 64 for maintenance.

[0027] When the wall-scraping cleaning mechanism 7 is working, it operates synchronously with the anti-clogging liquid suction mechanism 6. The rotating shaft 62 rotates under the drive of the motor 61, which drives the bevel gear 71 at the end away from the motor 61 to rotate. The bevel gear 71 meshes with the bevel gear 73 fixedly connected to one end of the rotating rod 72, thereby driving the rotating rod 72 to rotate on the inner side of the car plate 1. The pulley 74 fixedly connected to the other end of the rotating rod 72 rotates synchronously with the rotating rod 72. The pulley 74 drives the pulley 75 at the bottom of the car plate 1 to rotate through the belt 76 on the circumferential surface. The connecting rod 77 fixedly connected to the top of the pulley 75 rotates accordingly, and the scraper 78 fixedly connected to the circumferential surface of the connecting rod 77 rotates together with the connecting rod 77. Because the inner wall of the collection box 69 is located on the displacement trajectory of the oblique surface of the scraper 78 and the rotation radius of the scraper 78 is smaller than the inner wall radius of the collection box 69, the oblique surface of the scraper 78 can fit against the inner wall of the collection box 69 when it rotates, continuously scraping off the viscous pollutants attached to the box wall, avoiding the accumulation of pollutants that occupy the collection space or block the drainage channel, and ensuring that the collection box 69 always maintains sufficient volume for storing the recovered polluted liquid.
