Description

Technical Field

[0001] The present invention relates to the technical field of anti-seepage liquid perfusion equipment, and specifically refers to a gypsum-immobilized microbial anti-seepage liquid perfusion device, which can quickly and conveniently perfuse the gypsum-immobilized microbial anti-seepage liquid into the corresponding perfusion area, so that it can be filled in the gaps in the perfusion area at a high speed and high efficiency. Background Art

[0002] The microporous structure of gypsum can serve as a carrier for microorganisms, immobilizing them through adsorption or entrapment. Extracellular polymeric substances (EPS) produced by microbial metabolism can fill the gypsum pores, thereby enhancing the material's density. Consequently, gypsum-immobilized microbial anti-seepage solutions, which use gypsum as a base material and incorporate microbial agents and organic silicone waterproofing agents (such as sodium methyl silicate), have begun to be used.

[0003] Existing gypsum-immobilized microbial anti-seepage liquid is often used in the field of rock cracks and building crack anti-seepage. The configured gypsum-immobilized microbial anti-seepage liquid is poured into the cracks and gaps of building components through corresponding pouring equipment to achieve the effect of building anti-seepage. Most of the existing gypsum-immobilized microbial anti-seepage liquid pouring devices use a slurry pump to directly perform high-pressure grouting. Since the gaps in building components have a small flow cross-section, it is difficult to pour them into place even if the pouring pressure is high, and slurry is prone to bubble during the pouring process, resulting in a high material loss rate. Therefore, even if a higher pouring pressure is used to pour the gypsum-immobilized microbial anti-seepage liquid, the existing gypsum-immobilized microbial anti-seepage liquid pouring devices often have problems with low pouring efficiency and poor pouring effect during actual use, resulting in the anti-seepage treatment effect often failing to meet the design requirements.

[0004] Therefore, the purpose of this invention is to design a gypsum-immobilized microbial anti-seepage liquid perfusion device that can effectively reduce the pressure required for the perfusion process, thereby reducing the perfusion energy consumption and equipment cost; and can also significantly improve the perfusion efficiency and perfusion effect of the gypsum-immobilized microbial anti-seepage liquid. Summary of the Invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a gypsum-immobilized microorganism anti-seepage liquid perfusion device, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A gypsum-fixed microbial anti-seepage liquid perfusion device, comprising:

[0008] A slurry pump, the feed end of which is connected to the bottom side of the storage barrel for the gypsum-loaded microbial anti-seepage liquid;

[0009] A sealing plate is laid on the outside of the corresponding perfusion area to form a seal on the outside of the perfusion area;

[0010] The perfusion main pipe has closed upper and lower ends respectively, a perfusion hole is provided in the perfusion area, the perfusion main pipe is fixedly plugged into the center of the perfusion hole, and a plurality of corresponding upper injection holes are evenly distributed on the lower side of the top of the perfusion main pipe;

[0011] The perfusion branch pipe is sleeved at intervals on the bottom side of the perfusion main pipe, and the upper part of the perfusion branch pipe is provided with a down-filling hole extending to the outside of the perfusion main pipe. The perfusion main pipe and the perfusion branch pipe are respectively connected in parallel to the discharge end of the slurry pump through corresponding control valves;

[0012] A vent tube is sleeved at intervals at the center of the perfusion branch pipe and the perfusion main pipe, the upper portion of the vent tube is located below the top of the perfusion hole, and the bottom of the vent tube extends to the outside of the perfusion branch pipe and the perfusion main pipe, and is fixedly installed with a corresponding one-way valve;

[0013] The material injection lifting mechanism includes a fixed sleeve that is spaced apart and sleeved on the outside of the injection main pipe. The fixed sleeve is fixedly abutted against the middle of the injection hole. The fixed sleeve and the injection main pipe are fixedly connected through corresponding connecting rods. A piston plate located on the bottom side of the fixed sleeve is movably mounted on the injection main pipe. A number of corresponding buffer springs are evenly distributed and fixed between the piston plate and the connecting rod.

[0014] A corresponding guide hole is provided in the middle of the piston plate, and the perfusion main pipe includes rigid pipe parts spaced apart in an upper and lower manner. The opposite sides of the rigid pipe parts are respectively connected and fixed to the middle of the piston plate through corresponding metal bellows.

[0015] A sealing plug body is fixedly connected to the outer side of the rigid tube portion located at the lower part and abuts against the bottom side of the injection hole.

[0016] A corresponding trigger block is fixedly connected to the upper end surface of the piston plate, and a corresponding trigger mechanism is fixedly connected to the bottom side of the connecting rod. After the buffer spring is fully compressed, the trigger block touches the trigger mechanism, and the trigger mechanism sends a signal to the user that the buffer spring is fully compressed.

[0017] The trigger mechanism includes a control module, a signal transmission module connected to the control module, a trigger switch, and a power supply module. The control module is composed of an STM32F10x and its peripheral circuits, the signal transmission module is a Bluetooth module, and the power supply module is a miniature lithium battery. After the trigger block touches the trigger switch, the control module controls the signal transmission module to send a signal to the user that the buffer spring is fully compressed.

[0018] The control valve on the perfusion branch pipe is opened, the control valve on the perfusion main pipe is closed, and the slurry pump is started to perfuse the material outward through the lower injection hole; when the buffer spring is fully compressed, the slurry pump stops; after the slurry pump has been stopped for a period of time t1, it is started again to feed the material; when the slurry pump is started again to feed the material for a period of time t2 and the buffer spring continues to be fully compressed, the control valve on the perfusion branch pipe is closed, and the control valve on the perfusion main pipe is opened to perfuse the material outward through the upper injection hole, until the material perfused into the perfusion hole is output outward through the one-way valve of the air vent, and the perfusion work is completed.

[0019] The lower side of the top of the air-permeable tube is provided with a corresponding material-blocking plate in an arc shape. When the material is poured outward through the upper injection hole, the material-blocking plate blocks the material and makes the material diffuse downward to its periphery.

[0020] A stirring mechanism for stirring the gypsum-fixed microorganism anti-seepage liquid is provided in the material barrel.

[0021] Advantages of the present invention:

[0022] 1) Based on the perfusion main pipe, the present invention first adds a perfusion branch pipe and a vent pipe, and improves the overall coordination of the perfusion main pipe, the perfusion branch pipe, and the vent pipe; then, an injection lifting mechanism is added, which includes a fixed sleeve spaced apart on the outside of the perfusion main pipe, the fixed sleeve fixedly abuts against the middle of the perfusion hole in the perfusion area, and is fixedly connected to the perfusion main pipe through corresponding connecting rods. The most important thing is that a piston plate located on the bottom side of the fixed sleeve is movably mounted on the perfusion main pipe, and a number of corresponding buffer springs are evenly distributed and fixedly connected between the piston plate and the connecting rod.

[0023] During the injection process, the control valve on the injection branch pipe is opened, the control valve on the injection main pipe is closed, and the slurry pump is started to inject the material outward through the injection hole; when the buffer spring is compressed to the set distance, the slurry pump stops; after the slurry pump stops for a period of time, it is started again to feed. During the process of starting the slurry pump to feed, the buffer spring provides elastic support for the piston plate, thereby increasing the resistance to the upward movement of the raw material, allowing the raw material to be injected into the gap around the injection hole under higher pressure conditions; and when the slurry pump stops, the buffer spring recovers its deformation to push the piston plate downward, thereby forming downward pressure on the material on the bottom side of the piston plate to enhance the effect of the material flowing into the gap; at the same time, the downward piston plate will also form a vacuum on the upper side of the piston plate, allowing the material to enter the corresponding gap more efficiently and smoothly.

[0024] This can effectively reduce the pressure required for the injection process, thereby reducing injection energy consumption and equipment costs; and can also significantly improve the injection efficiency and injection effect of the gypsum-immobilized microbial anti-seepage liquid.

[0025] 2) In order to ensure sufficient sealing between the piston plate and the injection main pipe, the docking accuracy between the two is often required to be high. However, since the piston plate and the injection main pipe need to move relative to each other, and the injection main pipe itself is used to feed raw materials, a large gap often occurs between the piston plate and the injection main pipe, which in turn causes the piston plate to fail to operate. To solve this problem, the present invention first provides a guide hole in the middle of the piston plate, and then improves the design of the injection main pipe, which includes a rigid tube portion spaced apart above and below, and the opposite sides of the rigid tube portion are respectively connected and fixed to the middle of the piston plate through corresponding metal bellows. In this way, the elasticity of the metal bellows can be used to adapt to the movement of the piston plate, and can assist in improving the elastic driving effect of the piston plate, thereby effectively ensuring that the piston plate can continue to operate, thereby ensuring the practical effect of the present invention.

[0026] 3) A trigger block is fixedly connected to the upper end surface of the piston plate of the present invention, and a corresponding trigger mechanism is fixedly connected to the bottom side of the connecting rod. After the buffer spring is fully compressed, the trigger block touches the trigger mechanism, and the trigger mechanism sends a signal to the user that the buffer spring is fully compressed.

[0027] In the early stage of perfusion, the control valve on the perfusion branch is opened, and the material is perfused outward through the lower injection hole. When the buffer spring is fully compressed, a signal is sent and the slurry pump is controlled to stop. After the slurry pump stops for a period of time t1, it is restarted to feed the material so as to gradually perfuse the raw materials into place. When the slurry pump is restarted to feed the material for a period of time t2 and the buffer spring is continuously fully compressed, it proves that the bottom area is fully perfused. At this time, the control valve on the perfusion main pipe is controlled to open, and the control valve on the perfusion branch is closed to perfuse the material outward through the upper injection hole until the material perfused into the perfusion hole is output outward through the one-way valve of the vent pipe, completing the perfusion work. By coordinating the design of the trigger block and the trigger mechanism, a signal is sent outward after the buffer spring is fully compressed, thereby effectively and significantly improving the controllability of the perfusion process of the present invention, thereby helping to improve the perfusion efficiency and perfusion effect of the gypsum-immobilized microbial anti-seepage liquid.

[0028] 4) The lower side of the top of the air vent of the present invention is provided with a corresponding material blocking plate in the shape of an arc. When the material is poured outward through the upper injection hole, the material blocking plate forms a barrier to the material, causing the material to diffuse downward toward its periphery, thereby preventing the material poured outward through the upper injection hole from being directly output through the air vent before fully entering the corresponding gap, thereby ensuring the pouring effect of the upper pouring area, thereby further assisting in improving the pouring effect of the gypsum-immobilized microbial anti-seepage liquid and further effectively ensuring the practical effect of the present invention.

DETAILED DESCRIPTION

[0034] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0035] refer to Figure 1-4 , a gypsum-fixed microbial anti-seepage liquid injection device, comprising:

[0036] A slurry pump 1, the feed end of which is connected to the bottom side of a storage barrel 2 for a gypsum-loaded microbial anti-seepage liquid;

[0037] The sealing plate 3 is laid on the outside of the corresponding pouring area 4 to form a seal on the outside of the pouring area 4. In this embodiment, the sealing plate 3 is made of a rigid plate with a rubber material layer connected to the upper part to adapt to the unevenness of the pouring area surface;

[0038] The perfusion main pipe 5 is closed at the upper and lower ends respectively. A perfusion hole 401 is provided in the perfusion area 4. The perfusion main pipe 5 is fixedly plugged into the center of the perfusion hole 401. A plurality of corresponding upper injection holes 501 are evenly distributed on the lower side of the top of the perfusion main pipe 5.

[0039] The perfusion branch pipe 6 is sleeved at intervals on the bottom side of the perfusion main pipe 5. The upper part of the perfusion branch pipe 6 is provided with a down-filling hole 601 extending to the outside of the perfusion main pipe 5. The perfusion main pipe 5 and the perfusion branch pipe 6 are respectively connected in parallel to the discharge end of the slurry pump 1 through corresponding control valves 7;

[0040] The ventilation tube 8 is spaced and sleeved at the center of the perfusion branch pipe 6 and the perfusion main pipe 5. The upper part of the ventilation tube 8 is located below the top of the perfusion hole 401, and the bottom of the ventilation tube 8 extends to the outside of the perfusion branch pipe 6 and the perfusion main pipe 5, and is fixedly installed with a corresponding one-way valve 801;

[0041] The injection lifting mechanism 9 includes a fixed sleeve 901 which is spaced apart and sleeved on the outside of the injection main pipe 5. The fixed sleeve 901 is fixedly abutted against the middle of the injection hole 401. The fixed sleeve 901 and the injection main pipe 5 are fixedly connected through corresponding connecting rods 10. A piston plate 902 located on the bottom side of the fixed sleeve 901 is movably mounted on the injection main pipe 5. A number of corresponding buffer springs 903 are evenly distributed and fixed between the piston plate 902 and the connecting rod 10.

[0042] On the basis of the perfusion main pipe 5, the present invention first adds a perfusion branch pipe 6 and a ventilation pipe 8, and improves the overall coordination of the perfusion main pipe 5, the perfusion branch pipe 6, and the ventilation pipe 8; then, an injection lifting mechanism 9 is added, which includes a fixed sleeve 901 that is spaced apart and sleeved on the outside of the perfusion main pipe 5, and the fixed sleeve 901 is fixedly abutted against the middle of the perfusion hole 401 of the perfusion area 4, and is fixedly connected to the perfusion main pipe 5 through the corresponding connecting rod 10. The most important thing is that a piston plate 902 located on the bottom side of the fixed sleeve 901 is movably installed on the perfusion main pipe 5, and a number of corresponding buffer springs 903 are evenly distributed and fixed between the piston plate 902 and the connecting rod 10.

[0043] During the injection process, the control valve on the injection branch pipe 6 is opened, the control valve on the injection main pipe 5 is closed, and the slurry pump 1 is started to inject the material outward through the injection hole 601. When the buffer spring 903 is compressed to a set distance, the slurry pump 1 stops. After the slurry pump 1 stops for a period of time, it is restarted to feed the material. When the slurry pump 1 is started to feed the material, the buffer spring 903 provides elastic support for the piston plate 902, thereby increasing the resistance to the upward movement of the material, allowing the material to be injected into the gap around the injection hole 401 under higher pressure conditions. When the slurry pump 1 is stopped, the buffer spring 903 recovers its deformation to push the piston plate 902 downward, thereby exerting downward pressure on the material on the bottom side of the piston plate 902, thereby improving the flow of the material into the gap. At the same time, the downward movement of the piston plate 902 also creates a vacuum on the upper side of the piston plate 902, allowing the material to enter the corresponding gap more efficiently and smoothly. This can effectively reduce the pressure required for the injection process, thereby reducing injection energy consumption and equipment costs; and can also significantly improve the injection efficiency and injection effect of the gypsum-immobilized microbial anti-seepage liquid.

[0044] A corresponding guide hole is provided in the middle of the piston plate 902. The main pouring pipe 5 includes upper and lower rigid pipe sections 502 spaced apart. Opposite sides of the rigid pipe sections 502 are connected and fixed to the middle of the piston plate 902 via corresponding metal bellows 503. A sealing plug 11 is fixed to the outer side of the lower rigid pipe section 502, which abuts the bottom side of the pouring hole 401.

[0045] To ensure adequate sealing between piston plate 902 and injection manifold 5, high precision is often required for their connection. However, due to the relative movement between piston plate 902 and injection manifold 5, and the fact that the latter is itself used for feeding raw materials, a large gap often exists between the two, leading to malfunction of piston plate 902. To address this issue, the present invention first provides a guide hole in the middle of piston plate 902. Then, the injection manifold 5 is improved to include rigid tube sections 502 spaced apart above and below. Opposite sides of the rigid tube sections 502 are connected and secured to the middle of piston plate 902 via corresponding metal bellows 503. This allows the elasticity of the metal bellows 503 to accommodate the movement of piston plate 902 and enhance the elastic drive effect on piston plate 902, effectively ensuring the continuous operation of piston plate 902 and the practical effects of the present invention.

[0046] A corresponding trigger block 12 is fixedly connected to the upper end surface of the piston plate 902, and a corresponding trigger mechanism 13 is fixedly connected to the bottom side of the connecting rod 10. After the buffer spring 903 is fully compressed, the trigger block 12 touches the trigger mechanism 13, and the trigger mechanism 13 sends a signal to the user that the buffer spring 903 is fully compressed.

[0047] The trigger mechanism 13 includes a control module 1301, a signal transmitting module 1302 connected to the control module 1301, a trigger switch 1303, and a power supply module 1304. The control module 1301 is composed of STM32F10x and its peripheral circuits, the signal transmitting module 1302 is a Bluetooth module, and the power supply module 1304 is a micro lithium battery. After the trigger block 12 touches the trigger switch 1303, the control module 1301 controls the signal transmitting module 1302 to send a signal to the user that the buffer spring 903 is fully compressed.

[0048] The control valve on the perfusion branch pipe 6 is opened, the control valve on the perfusion main pipe 5 is closed, and the slurry pump 1 is started to perfuse the material outward through the lower injection hole 601; when the buffer spring 903 is fully compressed, the slurry pump 1 is stopped; after the slurry pump 1 has been stopped for a period of time t1, it is started again to feed the material; when the slurry pump 1 is started again to feed the material after a period of time t2, and the buffer spring 903 continues to be fully compressed, the control valve on the perfusion branch pipe 6 is closed, and the control valve on the perfusion main pipe 5 is opened to perfuse the material outward through the upper injection hole 501, until the material perfused into the perfusion hole 401 is output outward through the one-way valve 801 of the air vent pipe 8, and the perfusion work is completed.

[0049] During the initial stage of priming, the control valve 7 on the priming branch pipe 6 is opened, and the material is priming outwards through the lower injection hole 601. When the buffer spring 903 is fully compressed, a signal is sent to control the slurry pump 1 to stop. After the slurry pump 1 has been stopped for a period of time t1, it is restarted to feed the material, gradually priming the material into place. When the slurry pump 1 is restarted to feed the material for a period of time t2, and the buffer spring 903 remains fully compressed, it indicates that the bottom area has been priming into place. At this time, the control valve 7 on the priming main pipe 5 is opened, and the control valve 7 on the priming branch pipe 6 is closed, so that the material is priming outwards through the upper injection hole 501. The priming process is completed when the material priming into the priming hole 401 is discharged outwards through the one-way valve of the vent pipe 8. The trigger block 12 and the trigger mechanism 13 are designed to cooperate so as to send a signal outward after the buffer spring 903 is fully compressed, thereby effectively and significantly improving the controllability of the perfusion process of the present invention, thereby helping to improve the perfusion efficiency and perfusion effect of the gypsum-immobilized microbial anti-seepage liquid.

[0050] The lower side of the top of the air permeable tube 8 is provided with a corresponding material blocking plate 14 in an arc shape. When the material is poured outward through the upper injection hole 501, the material blocking plate 14 blocks the material, causing the material to diffuse downward to its periphery, thereby preventing the material poured outward through the upper injection hole 501 from being directly output through the air permeable tube 8 before fully entering the corresponding gap, thereby ensuring the pouring effect of the upper pouring area, thereby further assisting in improving the pouring effect of the gypsum-fixed microbial anti-seepage liquid and effectively further ensuring the practical effect of the present invention.

[0051] The barrel 2 is provided with a stirring mechanism 15 for stirring the gypsum-immobilized microorganism anti-seepage liquid. The stirring mechanism 15 is used to maintain the uniformity of the gypsum-immobilized microorganism anti-seepage liquid stored in the barrel 2 .

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
