Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a cleaning device for the filtrate pipeline of a filter press. Background Technique

[0002] During the rolling of raw material steel pipes, steel plates, stainless steel, etc., mill scales will be formed on the pipelines. During the manufacturing, storage, transportation and installation processes of the pipelines, rust, welding slag and oily rust inhibitors coated on the pipelines for anti-corrosion, as well as impurities such as dust, sand, cement, and thermal insulation materials will be formed. Various impurities such as the above-mentioned mill scales, rust, welding slag, rust inhibitors and sediment seriously affect the normal use of the pipelines. Therefore, the pipelines need to be cleaned to restore the surface of the pipeline material itself.

[0003] At present, the existing pipeline cleaning devices usually directly flush the pipelines by spraying water with a high-pressure water gun. This method has a weak cleaning effect and cannot completely clean the stains inside the pipelines. At the same time, because the pressure of the high-pressure water gun is relatively large, it is very easy to cause damage to the pipelines. Moreover, most cleaning devices mainly focus on flushing, and there is no filtering system for the pipelines inserted into the water tank, which is easy to cause impurities in the water tank to enter the water pipe, which may lead to pipeline blockage and equipment damage. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a cleaning device for the filtrate pipeline of a filter press, which has the advantages of stronger decontamination and prevention of blockage, and solves the problems of weak cleaning effect and easy blockage inside the water pipe.

[0005] To achieve the above-mentioned purpose of rapid stirring and prevention of blockage, the utility model provides the following technical solutions: A cleaning device for the filtrate pipeline of a filter press, including a water storage tank, a bottom tank is fixedly installed at the bottom of the water storage tank, and a stirring mechanism and a water pumping mechanism extending into the bottom tank are arranged inside the water storage tank;

[0006] The stirring mechanism includes a servo motor, a first bearing and a second bearing. The servo motor is fixedly installed at the inner bottom of the bottom tank. The first bearing and the second bearing are fixedly installed at the upper and lower ends inside the water storage tank. The inner walls of the first bearing and the second bearing are fixedly connected with a stirring rod extending into the bottom tank, and a plurality of stirring blades are fixedly installed on the outside of the stirring rod.

[0007] Further, the water pumping mechanism includes a water pump. The water pump is fixedly installed at the inner bottom of the bottom tank. The top water pumping end of the water pump is fixedly connected with a diversion pipe extending into the water storage tank. The top of the diversion pipe is fixedly installed with a water pumping head, a filter screen is arranged at the top of the water pumping head, and the water outlet end of the water pump is fixedly connected with a drain pipe extending outside the bottom tank.

[0008] Further, a third bearing is fixedly installed outside the water storage tank. A rotating rod is fixedly connected to the inner wall of the third bearing. Fixing plates are fixedly installed at both the left and right ends of the outer part of the rotating rod.

[0009] Further, one end of the drain pipe extending outside the bottom box is movably connected to a flushing pipe, and a control valve is arranged outside the flushing pipe.

[0010] Further, one end of the stirring rod extending into the bottom box is fixedly connected to the output end of the servo motor.

[0011] Further, four pulleys are fixedly installed at the bottom of the bottom box. A control panel is fixedly installed outside the bottom box. A box cover is movably installed at the top of the water storage tank, and an observation window is arranged outside the water storage tank.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] 1. For this filter press filtrate pipeline cleaning device, by setting up a stirring mechanism, when the servo motor operates, the driving end of the servo motor drives the stirring rod to rotate. Through the bearings fixedly connected to both the upper and lower ends of the stirring rod, the stirring rod can rotate stably. While the stirring rod rotates stably, it will drive the stirring blades on the rod body to move, and the stirring blades will rotate horizontally with the stirring rod as the center, so that the water inside can be stirred and mixed with the washing substances, making the generated washing liquid have a uniform composition, enhancing the cleaning effect, and at the same time reducing the process of pre-mixing the washing liquid, improving the working efficiency of cleaning.

[0014] 2. For this filter press filtrate pipeline cleaning device, by setting up a water pumping mechanism, the mixed and stirred washing substances will, under the action of the water pump, make the washing liquid enter the diversion pipe through the water pumping head. The water in the diversion pipe then enters the drain pipe through the water pump, and the drain pipe transports the washing liquid to the flushing pipe. At this time, the washing liquid passes through the filter screen arranged at the top of the water pumping head, which can isolate the impurities generated after the water and the washing substances are mixed and stirred outside the pipeline, preventing the impurities from entering the pipeline and the inside of the water pump, causing pipeline blockage or water pump damage.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , a cleaning device for the filtrate pipeline of a belt filter in this embodiment includes a water storage tank 1. A bottom tank 2 is fixedly installed at the bottom of the water storage tank 1. A stirring mechanism 3 and a water pumping mechanism 4 extending into the interior of the bottom tank 2 are arranged inside the water storage tank 1;

[0022] The stirring mechanism 3 includes a servo motor 301, a first bearing 302 and a second bearing 303. The servo motor 301 is fixedly installed at the inner bottom of the bottom tank 2. The upper and lower ends inside the water storage tank 1 are both fixedly installed with the first bearing 302 and the second bearing 303. The inner walls of the first bearing 302 and the second bearing 303 are fixedly connected with a stirring rod 304 extending into the interior of the bottom tank 2. One end of the stirring rod 304 extending into the interior of the bottom tank 2 is fixedly connected to the output end of the servo motor 301. When the servo motor 301 drives the stirring rod 304 to rotate, stable rotation can be generated through the bearings at the upper and lower ends of the stirring rod 304. A plurality of stirring blades 305 are fixedly installed on the outer part of the stirring rod 304. While the stirring rod 304 rotates stably, the stirring blades 305 on the rod body will be driven to move. The stirring blades 305 will rotate horizontally with the stirring rod 304 as the center, so that the water and the washing substances inside can be stirred and fused, making the components of the generated washing liquid uniform, enhancing the cleaning effect, optimizing the process of preparing the washing liquid in advance at the same time, and improving the working efficiency of cleaning.

[0023] In the case implementation, the pumping mechanism 4 includes a water pump 401. The water pump 401 is fixedly installed at the inner bottom of the bottom box 2. The top water pumping end of the water pump 401 is fixedly connected to a diversion pipe 402 extending into the interior of the water storage tank 1. The top of the diversion pipe 402 is fixedly installed with a water pumping head 403. When the water pump 401 is started, the water pumping head 403 will pump the washing liquid inside the water storage tank 1 and after mixing and stirring into the diversion pipe 402, and then enter the interior of the water pump 401 through the diversion pipe 402. A filter screen 404 is arranged at the top of the water pumping head 403, which can isolate the impurities generated after mixing water and washing substances outside the pipeline, avoiding impurities entering the pipeline and the interior of the water pump 401, causing pipeline blockage or damage to the water pump 401. The water outlet end of the water pump 401 is fixedly connected to a drain pipe 405 extending outside the bottom box 2, which can transport the filtered clean washing liquid into the drain pipe 405 and wait for use.

[0024] In the case implementation, a third bearing 5 is fixedly installed outside the water storage tank 1. The inner wall of the third bearing 5 is fixedly connected to a rotating rod 6, enabling the rotating rod 6 to rotate stably. Fixing plates 7 are fixedly installed at both the left and right ends of the outside of the rotating rod 6, and the excess flushing pipes 8 can be wound around the rotating rod 6 between the two fixing plates 7, facilitating storage.

[0025] In the case implementation, one end of the drain pipe 405 extending outside the bottom box 2 is movably connected to a flushing pipe 8. A control valve 9 is arranged on the outside of the flushing pipe 8, and the amount of water flowing out at the nozzle can be controlled by adjusting the control valve 9, facilitating cleaning.

[0026] In the case implementation, four pulleys 10 are fixedly installed at the bottom of the bottom box 2, facilitating movement. A control panel 11 is fixedly installed outside the bottom box 2. The control panel 11 and the electronic components in this patent are all electrically connected through wires, thereby facilitating the operation of the control panel 11 to control the operation of the electronic components. A box cover 12 is movably installed at the top of the water storage tank 1, facilitating the addition of water and washing substances at any time. An observation window 13 is arranged outside the water storage tank 1, through which the water volume inside the water storage tank 1 can be observed to facilitate replenishment at any time.

[0027] During implementation, the operations are carried out according to the following steps:

[0028] 1) First, open the box cover 12 and add water and washing substances into the water storage tank 1;

[0029] 2) Then start the stirring mechanism 3, and mix and stir the water and washing substances inside the water storage tank 1 through the stirring blades 305;

[0030] 3) Then start the pumping mechanism 4, and transport the stirred washing liquid inside the water storage tank 1 to the flushing pipe 8 through the water pump 401;

[0031] 4) Finally, adjust the control valve 9 to clean the pipeline by spraying the cleaning liquid inside the flushing pipe 8 through the nozzle.

[0032] In summary, for the cleaning device of the filtrate pipeline of the belt filter, by setting the stirring mechanism 3, when the servo motor 301 operates, the driving end of the servo motor 301 drives the stirring rod 304 to rotate. Through the bearings fixedly connected to both the upper and lower ends of the stirring rod 304, the stirring rod 304 can rotate stably. While the stirring rod 304 rotates stably, it will drive the stirring blades 305 on the rod body to move. The stirring blades 305 will rotate horizontally with the stirring rod 304 as the center, so that the water and the washing substances inside can be stirred and blended, making the components of the generated cleaning liquid uniform, enhancing the cleaning effect, reducing the process of pre-mixing the cleaning liquid, improving the working efficiency of cleaning, and solving the problem that the existing pipeline cleaning devices usually directly flush the pipeline by spraying water with a high-pressure water gun. This method has a weak cleaning effect and cannot completely clean the stains inside the pipe. At the same time, due to the high pressure of the high-pressure water gun, it is also easy to cause pipeline damage.

[0033] Moreover, by setting the water pumping mechanism 4, the mixed and stirred washing substances will, under the action of the water pump 401, make the cleaning liquid enter the diversion pipe 402 through the water pumping head 403. The water in the diversion pipe 402 then enters the drain pipe 405 through the water pump 401, and the drain pipe 405 transports the cleaning liquid to the flushing pipe 8. At this time, the cleaning liquid passes through the filter screen 404 arranged at the top of the water pumping head 403, which can isolate the impurities generated after mixing and stirring the water and the washing substances outside the pipeline, preventing the impurities from entering the pipeline and the inside of the water pump 401, causing pipeline blockage or water pump 401 damage, and solving the problem that most cleaning devices mainly focus on flushing, and the pipelines inserted into the water tank have no filtering system, which easily leads to impurities in the water tank entering the water pipe, possibly causing pipeline blockage and equipment damage.
