Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment plant construction, in particular to a device for laying waterproof coiled materials for a sewage treatment plant tank. Background Art

[0002] Sewage treatment pools can be divided into the following core types according to the process stage and treatment objectives: sedimentation tanks, biochemical pools. The waterproof effect of these pools is very important when treating sewage. When the pool is built, waterproof membrane laying equipment is needed to lay a layer of waterproof membrane on the surface of the pool to ensure the waterproofness of the pool. However, the existing waterproof membrane laying equipment has the following deficiencies when laying waterproof membrane on the sewage treatment plant pool: There is a certain amount of dust on the surface of the sewage treatment plant pool, which is only cleaned manually before laying, which not only has a poor cleaning effect, but also has a poor cleaning effect. It is not good and is time-consuming and labor-intensive. During the laying process, the surface of the pool body cannot be dusted again efficiently, resulting in dust particles remaining between the waterproof membrane and the surface of the pool body to form bulges, which reduces the firmness of the waterproof membrane when laid on the surface of the pool body. In addition, during the process of unwinding the waterproof membrane through the unwinding roller, as the diameter of the rolled membrane on the unwinding roller becomes smaller, the unwinding speed of the membrane will become faster. At this time, the tension of the membrane on the unwinding roller is reduced, and the membrane is prone to wrinkles and curling during laying, which reduces the flatness of the waterproof membrane laid on the surface of the pool body.

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The present invention provides a sewage treatment plant pool body waterproofing coil laying equipment, see Figure 1-3 , including: a mobile vehicle 200, with mobile wheels 210 installed at the bottom for moving the equipment; a laying host 100, installed on the mobile vehicle 200, for laying a waterproof membrane; a flattening mechanism 300, installed at the front end of the laying host 100, for flattening the waterproof membrane to the ground.

[0023] In one embodiment, a flattening mechanism 300 is provided at the front end of the laying main machine 100, and a rotating connecting rod 310 provided on the flattening mechanism 300 is connected to the front end shaft of the laying main machine 100. A heating roller 320 is provided on the inner side of the rotating connecting rod 310, and a supporting connecting rod 330 is fixedly installed on the inner side of the rotating connecting rod 310. A spring rod 340 is provided inside the upper end of the supporting connecting rod 330 to elastically adjust the length of the supporting connecting rod 330. A top support plate 350 is also fixedly installed on the top of the supporting connecting rod 330 to support the A flattening roller 390 is provided on the inner side of the lower end of the support link 330, a lower pressure rod 360 is provided on the bottom surface of the top support plate 350, a pressing plate 370 is welded to the lower end of the lower pressure rod 360, a roller 380 is embedded on the bottom surface of the pressing plate 370, and a shaft sleeve 392 is provided at the lower end of the support link 330. A rotating shaft 391 is rotatably installed inside the shaft sleeve 392, and the rotating shaft 391 is set at the axis of the flattening roller 390, so that the flattening roller 390 rotates on the inner side of the lower end of the support link 330 to apply pressure when the waterproof membrane 10 is laid.

[0024] The control box 110 provided at the upper end of the laying host 100 energizes the heating roller 320. After the heating roller 320 is energized, the temperature rises to heat the bottom surface of the waterproof membrane 10, thereby improving the adhesion effect between the waterproof membrane 10 and the surface of the sewage treatment plant tank.

[0025] There are three lower pressure rods 360 and pressing plates 370, which are laterally distributed on the upper surface of the flattening roller 390. The arc-shaped structure of the pressing plate 370 matches the structure of the flattening roller 390. The lower pressure rod 360 applies downward pressure to the pressing plate 370 to increase the force of the flattening roller 390 in rolling and pressing the waterproof membrane 10. The roller 380 and the flattening roller 390 assist in sliding to avoid jamming between the flattening roller 390 and the pressing plate 370, thereby ensuring that the waterproof membrane 10 is firmly bonded and laid on the surface of the sewage treatment plant tank.

[0026] In one embodiment, see Figure 4-6 The end of the mobile vehicle 200 close to the flattening mechanism 300 is provided with a motor 410, the output end of the motor 410 drives the first belt 420 for transmission, the other end of the first belt 420 is connected to a pulley 430, a rotator 431 is welded to the bottom of the pulley 430, and a brush 432 is provided on the bottom of the rotator 431 to clean the surface of the sewage treatment plant pool. The rotator 431 and the brush 432 are located on the side of the flattening roller 390 close to the mobile vehicle 200, and an air guide pipe 440 is also installed on the upper end of the pulley 430 with a clearance fit. An air inlet groove 453 is provided at the upper end of the air guide tube 440. The end of the air inlet groove 453 away from the air guide tube 400 is connected to the negative pressure chamber 450. A positioning ring 451 is provided at the outer end of the negative pressure chamber 450, and a locker 470 is provided on the edge of the positioning ring 451. A disassembly shell 454 is installed inside the negative pressure chamber 450, and a filter 455 is installed inside the disassembly shell 454. A dust collector 460 is also installed outside the positioning ring 451, and the dust collector 460 is locked and fixed to the outside of the positioning ring 451 by the locker 470. A knob 471 is mounted on the surface of the lock 470, and a gear 472 is provided at the lower end of the knob 471. A pinch plate 473 is slidably mounted inside the lock 470 and elastically limited by a tension spring 476 provided inside the lock 470. A rack 475 is welded on the surface of the pinch plate 473, and the gear 472 meshes with the rack 475. The knob 471 is turned to drive the pinch plate 473 to slide left and right inside the lock 470. The pinch plate 473 is buckled with the end of the vacuum cleaner 460 close to the positioning ring 451. A positioning pin 474 is further provided inside the outer side of the pinch plate 473. The positioning pin 474 is plugged into the positioning hole 461 provided at the front end of the vacuum cleaner 460. A second belt 480 is also connected to the pulley 430, and the synchronous transmission of the second belt 480 causes the three pulleys 430 to rotate synchronously, driving the rotator 431 and the brush 432 to comprehensively clean the surface of the sewage treatment plant pool before the waterproof membrane 10 is laid, to prevent dust particles from remaining between the waterproof membrane 10 and the pool surface to form bulges. The vacuum cleaner 460 generates suction to form a negative pressure inside the negative pressure cavity 450, and the dust particles on the surface of the sewage treatment plant pool at the bottom of the rotator 431 are sucked in through the three air ducts 440, thereby improving the cleaning effect of the dust particles on the surface of the sewage treatment plant pool.

[0027] There are four lockers 470, which are distributed at four positions on the edge of the positioning ring 451. The front end of the vacuum cleaner 460 is locked by sliding the buckle plates 473 on the four lockers 470, and the positioning pin 474 is inserted into the positioning hole 461, which improves the convenience of disassembly and assembly of the vacuum cleaner 460 at the outer end of the negative pressure chamber 450, so that the disassembly shell 454 can be disassembled and assembled to clean the filter 455.

[0028] In one embodiment, see Figure 1 、 4 , 7 and 8, a transmission roller 120 is provided above the front and rear ends of the laying main body 100, a guide roller 130 is installed at the middle end of the upper interior of the laying main body 100, a side guide 140 is welded to the inner wall of the upper end of the laying main body 100 to clamp and guide the side of the waterproof membrane 10, and a dust inlet 150 is penetrated inside the upper part of the laying main body 100, and the dust inlet 150 is connected to the lower suction port 452 provided at the upper end of the negative pressure chamber 450 to absorb and clean the lower surface of the waterproof membrane 10; The front side of the laying main machine 100 is welded with positioning support blocks 180 to support the two rotating connecting rods 310 after they are rotated to the horizontal position. The top surface of the front end of the laying main machine 100 is installed with a moving block 190. The moving block 190 is buckled and fixed after the rotating connecting rod 310 is rotated to the vertical position. The rear end of the moving block 190 is provided with a pulling block 192, and the lower end of the pulling block 192 is clearance-fitted with a spring top rod 191, which is fixedly installed inside the upper end of the laying main machine 100. A sealing cylinder 160 is installed at the rear of the laying main machine 100. The sealing cylinder 160 is set on the mobile vehicle 200. On the upper surface, the upper end of the sealing cylinder 160 is connected to the top cylinder 170 through a hinge, and the inner axis of the sealing cylinder 160 is provided with a reeling roller 161 to reel the rolled waterproof membrane 10, and the sealing cylinder 160 and the top cylinder 170 are both provided with a pressing roller 171, which contacts the outer surface of the rolled waterproof membrane 10, and the axis of the pressing roller 171 is provided with an axis sleeve 175, and the upper end of the axis sleeve 175 is provided with a connecting rod 172 and the axis is connected, and the upper end of the connecting rod 172 is provided with a slider 173 and the axis is connected, and the slider 173 moves elastically along the spring guide rod 174 inside the sealing cylinder 160 and the top cylinder 170; There are two movable blocks 190, two pulling blocks 192, and two spring push rods 191, which are symmetrically mounted on the front end of the laying machine 100. The spring push rods 191 provide elastic movement for the movable blocks 190, ensuring that the movable blocks 190 can stably engage and fix the rotating connecting rod 310 after it is rotated to the vertical position. After the laying work is completed, the flattening roller 390 can be flipped up for fixed storage, preventing the flattening roller 390 from always being at the bottom and contacting the ground during movement, thereby preventing wear. The two pressing rollers 171, the axial sleeve 175, the connecting rod 172, the slider 173 and the spring guide rod 174 are installed symmetrically in the upper and lower parts inside the sealing cylinder 160 and the top cylinder 170. The spring guide rod 174 applies elastic sliding force to the slider 173, and the pressing roller 171 is automatically adjusted under the linkage of the connecting rod 172. As the rolled waterproof membrane 10 is unwound, the diameter becomes smaller, and the pressing roller 171 is automatically adjusted to always contact the outer surface of the waterproof membrane 10, thereby controlling the unwinding speed of the waterproof membrane 10 and avoiding the occurrence of wrinkles and curling due to a decrease in the tension of the waterproof membrane 10, thereby improving the flatness of the waterproof membrane 10 laid on the surface of the pool.

[0029] The present invention provides a method for using a sewage treatment plant tank body waterproofing coil laying device, comprising the following steps: Step 1: Pull the waterproof membrane out of the device and heat it.

[0030] The waterproof membrane 10 is pulled out from the inside of the sealing cylinder 160, and passes through the upper end of the laying main machine 100 under the conduction of the transmission roller 120. The waterproof membrane 10 is guided by the guide roller 130 inside the laying main machine 100, and the side guide plate 140 clamps and guides the side of the waterproof membrane 10. Then the waterproof membrane 10 contacts and conducts with the heating roller 320 and is finally placed on the bottom surface of the flattening roller 390.

[0031] Step 2: Clean the area where the waterproof membrane is to be applied.

[0032] The starting motor 410 is driven by the first belt 420 and the pulley 430, and the three pulleys 430 and the three rotators 431 rotate synchronously. The brushes 432 under the three rotators 431 simultaneously clean the surface of the sewage treatment plant pool before the waterproof membrane 10 is laid. At the same time, the vacuum cleaner 460 generates suction to form a negative pressure inside the negative pressure cavity 450, and the dust particles on the surface of the sewage treatment plant pool at the bottom of the rotator 431 are sucked in through the three air ducts 440. In addition, during the laying process, as the mobile vehicle 200 moves, the dust particles on the surface of the sewage treatment plant pool are thoroughly cleaned.

[0033] Step 3: Clean the adhesive surface of the waterproof membrane.

[0034] When the vacuum cleaner 460 is working to vacuum, the dust inlet 150 generates a downward suction force under the penetration of the lower suction port 452 to adsorb and clean the lower surface of the waterproof membrane 10. All the dust particles adsorbed by the vacuum cleaner 460 are concentrated on the filter 455 inside the disassembly shell 454.

[0035] Step 4: Lay the waterproof membrane.

[0036] When laying the waterproof membrane 10 on the surface of the sewage treatment plant pool after cleaning, the pressing plate 370 is exerted with downward pressure by the pressing rod 360, and the roller 380 and the flattening roller 390 assist in sliding, so that the pressing plate 370 exerts downward pressure on the flattening roller 390, and ensures that the flattening roller 390 rolls normally to roll the waterproof membrane 10. After the flattening roller 390 rolls the waterproof membrane 10, the waterproof membrane 10 is firmly bonded and laid on the surface of the sewage treatment plant pool.

[0037] During the installation process, the rolled waterproof membrane 10 is unwound on the unwinding roller 161 inside the sealing tube 160. During unwinding, the spring guide rod 174 applies elastic sliding force to the slider 173 and the pressing roller 171 is automatically adjusted under the linkage of the linkage rod 172. As the rolled waterproof membrane 10 is unwound, the diameter becomes smaller, and the automatic adjustment of the pressing roller 171 always contacts the outer surface of the waterproof membrane 10, thereby controlling the unwinding speed of the waterproof membrane 10 and avoiding the situation where the tension of the waterproof membrane 10 decreases and wrinkles and curling occur.

[0038] Step 5: Finish laying.

[0039] After laying is completed, the knob 471 is turned to drive the gear 472 to rotate the meshing rack 475 to move and adjust the buckle plate 473. The buckle plate 473 is separated from the vacuum cleaner 460, and the positioning pin 474 is separated from the inside of the positioning hole 461. The vacuum cleaner 460 is quickly removed. At this time, the disassembly shell 454 inside the negative pressure chamber 450 is removed, and the internal filter 455 is cleaned.

[0040] The present invention adopts the synchronous transmission of the second belt 480 to make the three pulleys 430 rotate synchronously, driving the rotator 431 and the brush 432 to comprehensively clean the surface of the sewage treatment plant pool before the waterproof membrane 10 is laid, so as to avoid dust particles remaining between the waterproof membrane 10 and the pool surface to form bulges. The vacuum cleaner 460 generates suction to form a negative pressure inside the negative pressure cavity 450, and the dust particles on the surface of the sewage treatment plant pool at the bottom of the rotator 431 are sucked in through the three air ducts 440, thereby improving the cleaning effect of the dust particles on the surface of the sewage treatment plant pool, and solving the problem that the pool surface cannot be efficiently dust-removed again, resulting in dust particles remaining between the waterproof membrane and the pool surface to form bulges.

[0041] The present invention adopts two pressing rollers 171, an axial sleeve 175, a connecting rod 172, a slider 173 and a spring guide rod 174 which are symmetrically installed in the upper and lower parts of the sealing cylinder 160 and the top cylinder 170. The spring guide rod 174 applies elastic sliding force to the slider 173, and the pressing roller 171 is automatically adjusted under the linkage of the connecting rod 172. As the rolled waterproof membrane 10 is unwound, the diameter becomes smaller. The automatic adjustment of the pressing roller 171 always contacts the outer surface of the waterproof membrane 10, controls the unwinding speed of the waterproof membrane 10, and avoids the situation where the tension of the waterproof membrane 10 decreases and wrinkles and curling occur, thereby improving the flatness of the waterproof membrane 10 laid on the surface of the pool body, solving the problem that the roll material is prone to wrinkles and curling during laying, and reducing the flatness of the waterproof roll material laid on the surface of the pool body.

[0042] The present invention adopts a lower pressure rod 360 and a pressing plate 370 that are horizontally distributed on the upper surface of the flattening roller 390. The arc-shaped structure of the pressing plate 370 matches the structure of the flattening roller 390. The lower pressure rod 360 applies downward pressure to the pressing plate 370 to increase the force of the flattening roller 390 in rolling and pressing the waterproof membrane 10. The roller 380 and the flattening roller 390 assist in sliding to avoid jamming between the flattening roller 390 and the pressing plate 370, thereby ensuring that the waterproof membrane 10 is firmly bonded and laid on the surface of the sewage treatment plant tank body, solving the problem that the waterproof membrane 10 cannot be firmly bonded and laid on the surface of the sewage treatment plant tank body.

[0043] The present invention adopts a movable block 190, a pulling block 192 and a spring top rod 191 which are symmetrically installed on the front end top of the laying main machine 100. The spring top rod 191 applies elastic movement to the movable block 190 to ensure that the movable block 190 can stably engage and fix the rotating connecting rod 310 after it is rotated to a vertical position. After the laying work is completed, the flattening roller 390 can be flipped up for fixed storage, which solves the problem that the flattening roller 390 is always at the bottom and in contact with the ground during movement, causing wear.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
