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 microorganism anti-seepage liquid perfusion device, which can quickly and conveniently perfusion the gypsum-immobilized microorganism anti-seepage liquid into the corresponding perfusion area, so that it can quickly and efficiently fill the gaps in the perfusion area. Background Art

[0002] The microporous structure of gypsum can be used as a carrier for microorganisms, and the microbial flora can be fixed by adsorption or embedding methods. The extracellular polymeric substances (EPS) produced by microbial metabolism can fill the pores of gypsum, thereby enhancing the material density. Therefore, gypsum-immobilized microorganism anti-seepage liquid, which uses gypsum as the base material and then adds raw materials such as microbial agents and organosilicon waterproof agents (such as sodium methyl silicate), has begun to be put into use.

[0003] The existing gypsum-immobilized microorganism anti-seepage liquid is often used in the fields of rock crack and building crack anti-seepage. Through the corresponding perfusion equipment, the prepared gypsum-immobilized microorganism anti-seepage liquid is perfused into the cracks and gaps of building components to achieve the effect of building anti-seepage. Most of the existing gypsum-immobilized microorganism anti-seepage liquid perfusion devices directly use a slurry pump for high-pressure grouting treatment. Due to the problem of small flow cross-section in the gaps of building components, it is difficult to perfusion in place even with a large perfusion pressure, and slurry is likely to overflow during the perfusion process, resulting in a high loss rate of materials. Therefore, even when a relatively high perfusion pressure is used to perfusion the gypsum-immobilized microorganism anti-seepage liquid, the existing gypsum-immobilized microorganism anti-seepage liquid perfusion devices often still have problems of low perfusion efficiency and poor perfusion effect in actual use, resulting in the anti-seepage treatment effect often not meeting the design requirements.

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

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

[0006] The technical solution of the present invention is as follows: A gypsum-immobilized microorganism anti-seepage liquid perfusion device, comprising: A slurry pump, the feed end of which is connected to the bottom side of the storage bucket for the gypsum-immobilized microorganism anti-seepage liquid; A sealing plate, which is laid on the outside of the corresponding perfusion area and is used to form a seal on the outside of the perfusion area; The perfusion main pipe is closed at both the upper and lower ends. There are perfusion holes provided within the perfusion area. The perfusion main pipe is fixedly inserted at the center of the perfusion holes. A number of corresponding upper feeding holes are evenly distributed on the lower side of the top of the perfusion main pipe. The perfusion branch pipes are sleeved at intervals on the bottom side of the perfusion main pipe. The upper part of the perfusion branch pipes is provided with lower feeding holes extending to the outside of the perfusion main pipe. The perfusion main pipe and the perfusion branch pipes are respectively connected in parallel to the discharge end of the slurry pump through corresponding control valves. The air permeable pipes are sleeved at intervals at the centers of the perfusion branch pipes and the perfusion main pipe. The upper part of the air permeable pipes is located under the lower side of the top of the perfusion holes. The bottom of the air permeable pipes extends to the outside of the perfusion branch pipes and the perfusion main pipe, and corresponding one-way valves are fixedly installed. The feeding lifting mechanism includes a fixed sleeve sleeved at intervals on the outside of the perfusion main pipe. The fixed sleeve is fixedly abutted against the middle part of the perfusion holes. A fixed connection is formed between the fixed sleeve and the perfusion main pipe through corresponding connecting rods. A piston plate located at the bottom side of the fixed sleeve is movably installed on the perfusion main pipe. A number of corresponding buffer springs are evenly fixedly connected between the piston plate and the connecting rods.

[0007] A corresponding guide hole is provided in the middle of the piston plate. The perfusion main pipe includes rigid pipe parts arranged at intervals up and down. The opposite sides of the rigid pipe parts are respectively connected and fixed to the middle of the piston plate through corresponding metal bellows.

[0008] A sealing plug body that abuts against the bottom side of the perfusion hole is fixedly connected to the outside of the rigid pipe part located at the lower part.

[0009] A corresponding trigger block is fixedly connected to the upper end surface of the piston plate. A corresponding trigger mechanism is fixedly connected to the bottom side of the connecting rod. After the buffer springs are completely compressed, the trigger block touches the trigger mechanism, and the trigger mechanism sends a signal that the buffer springs are completely compressed to the user.

[0010] The trigger mechanism includes a control module, a signal emission module, a trigger switch, and a power supply module connected to the control module. The control module is composed of STM32F10x and its peripheral circuits. The signal emission module is a Bluetooth module. The power supply module is a micro lithium battery. After the trigger block touches the trigger switch, the control module controls the signal emission module to send a signal that the buffer springs are completely compressed to the user.

[0011] 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 pour the material out through the lower feeding holes. When the buffer springs are completely compressed, the slurry pump stops operating. The downtime of the slurry pump is t 1After that, start feeding again; when the feeding time t of the slurry pump starts feeding again 2 After that, when the buffer spring has not been fully compressed, the control valve on the perfusion branch pipe closes, and the control valve on the perfusion main pipe opens to pour the material out through the upper feeding hole until the material poured into the perfusion hole is output out through the one-way valve of the air permeable pipe, and the perfusion work is completed.

[0012] A corresponding material blocking plate member is arranged in an arc shape on the lower side of the top of the air permeable pipe. When the material is poured out through the upper feeding hole, the material blocking plate member blocks the material, causing the material to spread downward to its periphery.

[0013] A stirring mechanism for stirring the gypsum-fixed microorganism anti-seepage liquid is arranged in the material bucket.

[0014] Advantages of the present invention: 1) On the basis of the perfusion main pipe, the present invention is first provided with a perfusion branch pipe and an air permeable pipe, and the overall cooperation of the perfusion main pipe, the perfusion branch pipe, and the air permeable pipe is improved; then a feeding lifting mechanism is provided, which includes a fixed sleeve arranged at intervals outside the perfusion main pipe. The fixed sleeve is fixedly abutted 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 can be movably installed on the perfusion main pipe at the bottom side of the fixed sleeve, and a plurality of corresponding buffer springs are uniformly fixedly connected between the piston plate and the connecting rods.

[0015] During the perfusion process, the control valve on the perfusion branch pipe opens, and the control valve on the perfusion main pipe closes. The slurry pump starts to pour the material out through the lower feeding hole; when the buffer spring is compressed by a set distance, the slurry pump stops operating; after the slurry pump stops operating for a period of time, it starts feeding again. During the process of the slurry pump starting to feed, the buffer spring provides an elastic supporting force for the piston plate, thereby increasing the resistance of the raw material to move upward, so that the raw material can be poured into the gaps around the perfusion hole under high pressure conditions; during the process of the slurry pump stopping operating, the buffer spring restores its deformation to push the piston plate downward, thereby forming a downward pressure on the material at the bottom side of the piston plate to improve the effect of the material flowing to the gap; at the same time, the downward moving piston plate will also create a vacuum on the upper side of the piston plate, making the material more efficient and smooth to enter the corresponding gap.

[0016] Thereby, it can effectively reduce the pressure required during the perfusion process to reduce the perfusion energy consumption and the cost of the equipment; and it can also significantly improve the low perfusion efficiency and perfusion effect of the gypsum-fixed microorganism anti-seepage liquid.

[0017] 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 in the cooperation between the piston plate and the injection main pipe, which leads to failure of the operation function of the piston plate. In order 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 pipe portion spaced apart above and below, and the opposite sides of the rigid pipe portion are respectively connected and fixed to the middle of the piston plate through corresponding metal bellows. In this way, the movement of the piston plate can be adapted by the elasticity of the metal bellows, and the elastic driving effect on the piston plate can be assisted to improve, thereby effectively ensuring that the piston plate can continue to operate, so as to ensure the practical effect of the present invention.

[0018] 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.

[0019] In the early stage of injection, the control valve on the injection branch pipe is opened, and the material is injected outward through the injection hole. When the buffer spring is fully compressed, a signal is sent to control the slurry pump to stop operating; the slurry pump stop time t 1 After that, it starts feeding again to gradually pour the raw materials into place. When the slurry pump starts feeding again, the time t 2 After that, when the buffer spring has not been fully compressed, it proves that the bottom area has been filled in place. At this time, the control valve on the main filling pipe is opened, and the control valve on the filling branch pipe is closed to fill the material outward through the upper filling hole until the material poured into the filling hole is output outward through the one-way valve of the air-permeable pipe. The filling work is completed. Through the coordinated 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 filling process of the present invention, so as to assist in improving the filling efficiency and filling effect of the gypsum-fixed microbial anti-seepage liquid.

[0020] 4) The lower side of the top of the air permeable tube of the present invention 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, causing the material to diffuse downward to its periphery, thereby preventing the material poured outward through the upper injection hole from being directly output through the air permeable tube 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 further effectively ensuring the practical effect of the present invention.

Specific embodiments

[0026] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the accompanying drawings for the embodiments: Refer to Figures 1-4 , a gypsum-immobilized microorganism anti-seepage liquid perfusion device, including: Slurry pump 1, the feed end of which is connected to the bottom side of the material barrel 2 for storing the gypsum-immobilized microorganism anti-seepage liquid; Sealing plate 3, laid on the outside of the corresponding perfusion area 4 for sealing the outside of the perfusion 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 surface of the perfusion area; Perfusion main pipe 5, with the upper and lower ends closed respectively. There is a perfusion hole 401 in the perfusion area 4, and the perfusion main pipe 5 is fixedly inserted into the center of the perfusion hole 401. A number of corresponding upper injection holes 501 are evenly arranged on the lower side of the top of the perfusion main pipe 5; Perfusion branch pipe 6, 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 lower injection 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; Breather pipe 8, sleeved at intervals in the centers of the perfusion branch pipe 6 and the perfusion main pipe 5. The upper part of the breather pipe 8 is located under the top of the perfusion hole 401. The bottom of the breather pipe 8 extends to the outside of the perfusion branch pipe 6 and the perfusion main pipe 5 and is fixedly installed with a corresponding check valve 801; The material injection lifting mechanism 9 includes a fixed sleeve 901 spaced around the outer side of the perfusion main pipe 5. The fixed sleeve 901 is fixedly abutted against the middle part of the perfusion hole 401. A fixed connection is formed between the fixed sleeve 901 and the perfusion main pipe 5 through corresponding connecting rods 10. A piston plate 902 is movably installed on the perfusion main pipe 5 at the bottom side of the fixed sleeve 901. A number of corresponding buffer springs 903 are evenly fixedly connected between the piston plate 902 and the connecting rods 10.

[0027] Based on the perfusion main pipe 5, the present invention first adds a perfusion branch pipe 6 and a vent pipe 8, and improves the overall cooperation design of the perfusion main pipe 5, the perfusion branch pipe 6, and the vent pipe 8. Then, a material injection lifting mechanism 9 is added, which includes a fixed sleeve 901 spaced around the outer side of the perfusion main pipe 5. The fixed sleeve 901 is fixedly abutted against the middle part of the perfusion hole 401 in the perfusion area 4. A fixed connection is formed between it and the perfusion main pipe 5 through corresponding connecting rods 10. Most importantly, a piston plate 902 is movably installed on the perfusion main pipe 5 at the bottom side of the fixed sleeve 901, and a number of corresponding buffer springs 903 are evenly fixedly connected between the piston plate 902 and the connecting rods 10.

[0028] During the perfusion process, the control valve on the perfusion branch pipe 6 is opened, and the control valve on the perfusion main pipe 5 is closed. The slurry pump 1 is started to pour the material outward through the lower material injection hole 601. When the buffer spring 903 is compressed by a set distance, the slurry pump 1 stops operating. After the slurry pump 1 stops operating for a period of time, it is started again for feeding. During the process of starting the slurry pump 1 for feeding, the buffer spring 903 provides an elastic supporting force for the piston plate 902, thereby increasing the resistance of the raw material to move upward, so that the raw material can be injected into the gap around the perfusion hole 401 under the condition of higher pressure. During the process of the slurry pump 1 stopping operating, the buffer spring 903 restores its deformation to push the piston plate 902 downward, thereby forming a downward pressure on the material at the bottom side of the piston plate 902 to improve the effect of the material flowing to the gap. At the same time, the downward moving piston plate 902 also creates a vacuum on the upper side of the piston plate 902, making the material enter the corresponding gap more efficiently and smoothly. Thus, it can effectively reduce the pressure required for the perfusion process to reduce the perfusion energy consumption and the cost of the equipment. And it can also significantly improve the perfusion efficiency and perfusion effect of the gypsum-fixed microorganism anti-seepage liquid.

[0029] A corresponding guide hole is provided in the middle of the piston plate 902. The perfusion main pipe 5 includes rigid pipe parts 502 arranged at intervals up and down. The opposite sides of the rigid pipe parts 502 are respectively connected and fixed to the middle of the piston plate 902 through corresponding metal bellows 503. A sealing plug body 11 that abuts against the bottom side of the perfusion hole 401 is fixedly connected to the outside of the lower rigid pipe part 502.

[0030] To ensure sufficient sealing between the piston plate 902 and the perfusion main pipe 5, a relatively high docking accuracy is often required between the two. However, since relative movement is needed between the piston plate 902 and the perfusion main pipe 5, and the perfusion main pipe 5 itself is used for raw material feeding, it is easy to have a relatively large gap between the piston plate 902 and the perfusion main pipe 5, which may lead to the failure of the operating function of the piston plate 902. To solve this problem, the present invention first provides a guide hole in the middle of the piston plate 902, and then improves the design of the perfusion main pipe 5, which includes a rigid pipe portion 502 arranged at intervals up and down. The opposite sides of the rigid pipe portion 502 are respectively connected and fixed to the middle of the piston plate 902 through corresponding metal bellows 503. In this way, the telescopic property of the metal bellows 503 can be used to adapt to the movement of the piston plate 902, and it can also assist in enhancing the elastic driving effect on the piston plate 902, thereby effectively ensuring that the piston plate 902 can operate continuously to ensure the practical effect of the present invention.

[0031] 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 completely compressed, the trigger block 12 touches the trigger mechanism 13, and the trigger mechanism 13 sends a signal that the buffer spring 903 is completely compressed to the user.

[0032] The trigger mechanism 13 includes a control module 1301, a signal emission 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 emission 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 emission module 1302 to send a signal that the buffer spring 903 is completely compressed to the user.

[0033] The control valve on the perfusion branch pipe 6 is opened, and the control valve on the perfusion main pipe 5 is closed. The slurry pump 1 is started to pour the material out through the lower pouring hole 601. When the buffer spring 903 is completely compressed, the slurry pump 1 stops operating; the shutdown duration t of the slurry pump 1 1 After that, it is started again for feeding. When the slurry pump 1 starts feeding again for a duration t 2 And when the buffer spring 903 has not been completely compressed yet, the control valve on the perfusion branch pipe 6 is closed, and the control valve on the perfusion main pipe 5 is opened to pour the material out through the upper pouring hole 501 until the material poured into the perfusion hole 401 is output outwards through the one-way valve 801 of the air vent pipe 8, and the perfusion work is completed.

[0034] Before perfusion, the control valve 7 on the perfusion branch pipe 6 is opened, and the material is perfused outward through the lower material injection hole 601. When the buffer spring 903 is completely compressed, a signal is sent out to control the slurry pump 1 to stop operating; the shutdown duration t of the slurry pump 1 1 After that, it is started again for feeding to gradually perfuse the raw materials in place. And when the feeding duration t of the slurry pump 1 starts again 2 After that, when the buffer spring 903 has not been completely compressed yet, it proves that the bottom area has been perfused in place. At this time, the control valve 7 on the perfusion main pipe 5 is opened, and the control valve 7 on the perfusion branch pipe 6 is closed to perfuse the material outward through the upper material injection hole 501 until the material perfused into the perfusion hole 401 is output outward through the one-way valve of the air vent pipe 8, and the perfusion work is completed. Through the cooperative design of the trigger block 12 and the trigger mechanism 13, a signal can be sent out outward after the buffer spring 903 is completely compressed, thereby effectively and greatly improving the controllability of the perfusion process of the present invention to assist in improving the low perfusion efficiency and perfusion effect of the gypsum-fixed microbial anti-seepage liquid.

[0035] A corresponding material blocking plate member 14 is arranged in an arc shape on the lower side of the top of the air vent pipe 8. When the material is perfused outward through the upper material injection hole 501, the material blocking plate member 14 blocks the material, causing the material to diffuse downward to its periphery, thereby preventing the material perfused outward through the upper material injection hole 501 from directly being output through the air vent pipe 8 before fully entering the corresponding gap, so as to ensure the perfusion effect of the upper perfusion area, thereby further assisting in improving the perfusion effect of the gypsum-fixed microbial anti-seepage liquid and effectively further ensuring the practical effect of the present invention.

[0036] A stirring mechanism 15 for stirring the gypsum-fixed microbial anti-seepage liquid is arranged in the material bucket 2. Through the intervention of the stirring mechanism 15, the uniformity of the gypsum-fixed microbial anti-seepage liquid stored in the material bucket 2 is maintained.

[0037] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
