Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a papermaking white water fiber recovery device. Background Technology

[0002] Papermaking white water fiber recovery devices are used to treat the white water generated during the papermaking process and recover fibers from it. The most commonly used device for white water recovery in existing technology is the papermaking white water fiber recovery microfiltration machine. This device is a rotary drum-type double-layer stainless steel screen filter. Its working principle is that water is filtered out by gravity through the screen, and the filtered fibers are guided by guide vanes on the inner screen surface, spiraling towards the pulp outlet until they are discharged, thus achieving recycling. This device has the advantages of small footprint, easy installation, convenient operation and management, no need for chemicals, and large production capacity. However, the filter screen on the papermaking white water fiber recovery microfiltration machine usually needs to be cleaned when the machine is stopped. Cleaning the filter screen usually requires disassembly, which takes a considerable amount of time, thus increasing time costs.

[0003] A papermaking white water fiber recovery device is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a papermaking white water fiber recovery device to solve the problem mentioned in the background art that the filter screen of the current papermaking white water fiber recovery microfiltration machine usually needs to be cleaned when the machine is stopped. When cleaning the filter screen, it is usually necessary to disassemble the filter screen for cleaning, which consumes a lot of time when disassembling and installing the filter screen, thus increasing the time cost to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a papermaking white water recycling fiber device, comprising a body, wherein water pumps are symmetrically installed on both sides of the top surface of the body;

[0006] A water inlet pipe is fixedly connected to one side surface of the water pump, and a water outlet pipe is fixedly connected to the top surface of the water pump. A fixing frame is connected through the surface of the water outlet pipe, and the fixing frame is fixedly connected to the main body. A conveying pipe is connected through the top surface of the water outlet pipe, and a stabilizing frame is connected through both sides of the conveying pipe. The bottom surface of the stabilizing frame is fixedly connected to the main body, and several adjustable rotating nozzles are connected through the surface of the conveying pipe.

[0007] Also includes:

[0008] The surface of the adjustable rotary nozzle is provided with protective components;

[0009] The protective components include a protective sleeve that is connected to the adjustable rotary nozzle.

[0010] Among them, threaded slide rods are symmetrically installed on both sides near the middle of the protective sleeve.

[0011] Preferably, a connecting plate is connected through the surface of the threaded slide rod, and a limit rod is fixedly connected to the side surface of the connecting plate near the top.

[0012] Preferably, a nut is threaded onto the surface of the threaded slide rod, and one side of the nut is fitted and connected to the connecting plate.

[0013] Preferably, a filter screen is fixedly installed on the bottom surface of the protective sleeve.

[0014] Preferably, the limiting rod is connected through the protective sleeve.

[0015] Preferably, the filter screen is made of stainless steel.

[0016] Preferably, the adjustable rotary nozzle has symmetrical limit holes on both sides near the bottom, and the limit holes are engaged with the limit rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This papermaking white water fiber recovery device, through the cooperation of the water pump, inlet pipe, outlet pipe, fixed frame, conveying pipe, stabilizing frame, adjustable rotating nozzle and protective components, reduces the frequency of filter screen disassembly when the entire device is shut down for cleaning, thereby avoiding an increase in time costs to a certain extent. The specific details are as follows:

[0018] 1. By installing a protective component, some fibers inevitably fall onto the adjustable rotary nozzle during the cleaning of the screen on the main body. These fibers may then enter the nozzle and cause blockage. The protective component reduces the amount of fiber entering the nozzle, thus minimizing the likelihood of blockage. During installation, the nut is turned to release pressure on the connecting plate, allowing it to slide on the threaded slide rod. The connecting plate and the threaded slide rod are connected in a through-type sliding connection, and the sliding of the connecting plate is not affected by the threads on the slide rod. The texture affects the movement of the limiting rod as the connecting plate slides. After the limiting rod and connecting plate move to the appropriate position, the connecting sleeve is placed on the adjustable rotary nozzle. The connecting plate and limiting rod are then pushed to move again, causing the limiting rod to engage with the limiting hole. The nut is then rotated, causing it to move along the threaded slide bar. This causes the nut to press against the connecting plate, preventing it from sliding on the threaded slide bar. This ensures a tighter engagement between the limiting rod and the limiting hole, guaranteeing the stability of the protective sleeve after installation on the adjustable rotary nozzle. Furthermore, the filter screen is made of stainless steel, allowing it to withstand high-pressure water jets and chemical corrosion in white water, extending its service life.

[0019] 2. By setting up a water pump, inlet pipe, outlet pipe, fixed frame, delivery pipe, stabilizing frame, and adjustable rotary nozzle, the water pump is connected to a control switch. A protective cover is added to the water pump as needed. The inlet pipe of the water pump can be connected to the treated white water tank. The treated white water is used to clean the screen on the main body, thus avoiding water waste. Simultaneously, through the cooperation of the outlet pipe and delivery pipe, water is sprayed through the adjustable rotary nozzle to clean the screen. The adjustable rotary nozzle is a four-hole rotary nozzle with adjustable speed. When cleaning the screen, by adjusting the spray rate and pressure of the adjustable rotary nozzle to a suitable level, even with the protective components on the adjustable rotary nozzle, it can still effectively clean the screen. The protective components have minimal impact on the water flow sprayed from the adjustable rotary nozzle. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a papermaking white water fiber recovery device, comprising a body 1, with water pumps 2 symmetrically installed on both sides of the top surface of the body 1; an inlet pipe 3 is fixedly connected to one side of the surface of the water pump 2, and an outlet pipe 4 is fixedly connected to the top surface of the water pump 2; a fixing frame 5 is connected through the surface of the outlet pipe 4, and the fixing frame 5 is fixedly connected to the body 1; a conveying pipe 6 is connected through the top surface of the outlet pipe 4; a stabilizing frame 7 is connected through both sides of the conveying pipe 6; the bottom surface of the stabilizing frame 7 is fixedly connected to the body 1; and a plurality of adjustable rotating nozzles 8 are connected through the surface of the conveying pipe 6; further comprising: a protective component 9 provided on the surface of the adjustable rotating nozzle 8; wherein the protective component 9 includes a protective sleeve 901 sleeved and connected to the adjustable rotating nozzle 8; wherein threaded slide rods 902 are symmetrically installed on both sides near the middle of the protective sleeve 901, such as... Figure 1-5As shown, the coordination between water pump 2, inlet pipe 3, outlet pipe 4, fixed frame 5, delivery pipe 6, stabilizing frame 7, adjustable rotating nozzle 8, and protective component 9 reduces the frequency of filter screen 906 disassembly during overall device shutdown cleaning, thus avoiding increased time costs to some extent. Furthermore, by setting up water pump 2, inlet pipe 3, outlet pipe 4, fixed frame 5, delivery pipe 6, stabilizing frame 7, and adjustable rotating nozzle 8, water pump 2 is connected to the control switch. A protective cover can be added to water pump 2 as needed. The inlet pipe 3 on water pump 2 can be connected to the treated white water tank. After treatment... The screen on the main body 1 is cleaned with white water, thus avoiding water waste. At the same time, through the cooperation of the water outlet pipe 4 and the conveying pipe 6, water is sprayed out through the adjustable rotary nozzle 8 to clean the screen. The adjustable rotary nozzle 8 is a four-hole rotary nozzle in the prior art, which has the function of adjustable speed. When cleaning the screen, by adjusting the spray rate and pressure of the adjustable rotary nozzle 8 to a suitable force, the screen can still be cleaned even if the adjustable rotary nozzle 8 is equipped with a protective component 9. The main body 1 is the prior art and the working principle is the same as the prior art.

[0028] A connecting plate 903 is connected through the surface of the threaded slide rod 902. A limit rod 904 is fixedly connected to the surface of the connecting plate 903 near the top. A nut 905 is threaded onto the surface of the threaded slide rod 902, and one side of the nut 905 is in contact with the connecting plate 903. A filter screen 906 is fixedly installed on the bottom surface of the protective sleeve 901. The limit rod 904 is connected through the protective sleeve 901. The filter screen 906 is made of stainless steel. Limit holes 10 are symmetrically opened on both sides near the bottom of the adjustable rotary nozzle 8. The limit holes 10 are engaged with the limit rod 904. Figure 3-5As shown, during the installation of the protective device, by rotating the nut 905, the nut 905 is no longer pressing against the connecting plate 903. This allows the connecting plate 903 to slide on the threaded slide rod 902 by pulling it. The connecting plate 903 and the threaded slide rod 902 are connected through a sliding connection. The sliding of the connecting plate 903 on the threaded slide rod 902 is not affected by the thread texture of the threaded slide rod 902. Simultaneously, the sliding of the connecting plate 903 causes the movement of the limiting rod 904. After the limiting rod 904 and the connecting plate 903 move to the appropriate position, the connecting sleeve is fitted onto the adjustable rotary nozzle 8. Then, the connecting plate 903 and the limiting rod 904 are pushed again, causing the limiting rod 904 to engage with the limiting hole 10. After the engagement is complete, the nut 905 is rotated again, causing it to move along the threaded connection on the threaded slide bar 902. This causes the nut 905 to press against the connecting plate 903, preventing it from sliding on the threaded slide bar 902. This allows for a tighter engagement between the limiting rod 904 and the limiting hole 10, ensuring the stability of the protective sleeve 901 after installation on the adjustable rotary nozzle 8. Meanwhile, the filter screen 906 is made of stainless steel, allowing it to withstand high-pressure water flow and chemical corrosion in white water, extending its service life. Furthermore, the threaded slide bar 902 and the nut 905 can be coated with anti-corrosion and anti-rust paint to slow down rusting.

[0029] Working principle: Before using this papermaking white water fiber recovery device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, by first setting the protective component 9, when cleaning the screen on the main body 1, some fibers inevitably fall onto the adjustable rotary nozzle 8, which may then enter the interior of the adjustable rotary nozzle 8, causing blockage. By installing the protective component 9 on the adjustable rotary nozzle 8, the amount of fibers entering the adjustable rotary nozzle 8 is reduced, thus reducing the possibility of blockage. Simultaneously, when installing the protective device, by rotating the nut 905, the nut 905 is no longer pressing against the connecting plate 903, allowing the connecting plate 903 to slide on the threaded slide rod 902 by pulling it. The connecting plate 903 and the threaded slide rod 902 are connected through a sliding connection, and the sliding of the connecting plate 903 on the threaded slide rod 902 is not affected by the thread texture of the threaded slide rod 902. When the connecting plate 903 slides, it causes the limiting rod 904 to move. After the limiting rod 904 and the connecting plate 903 move to the appropriate position, the connecting sleeve is placed on the adjustable rotary nozzle 8. Then, the connecting plate 903 and the limiting rod 904 are pushed to move again, so that the limiting rod 904 engages with the limiting hole 10. Then, the nut 905 is rotated, so that the nut 905 moves in a threaded connection on the threaded slide rod 902. This causes the nut 905 to squeeze the connecting plate 903, thus preventing the connecting plate 903 from sliding on the threaded slide rod 902. This makes the engagement between the limiting rod 904 and the limiting hole 10 tighter, ensuring the stability of the protective sleeve 901 after it is installed on the adjustable rotary nozzle 8. At the same time, the filter screen 906 is made of stainless steel, which allows the filter screen 906 to withstand the scouring of high-pressure water and the corrosion of chemicals in white water, extending the service life of the filter screen 906.

[0030] Secondly, by setting up a water pump 2, an inlet pipe 3, an outlet pipe 4, a fixing frame 5, a conveying pipe 6, a stabilizing frame 7, and an adjustable rotary nozzle 8, the water pump 2 is connected to a control switch. At the same time, a protective cover is added to the water pump 2 according to the actual situation. The inlet pipe 3 on the water pump 2 can be connected to the treated white water pool. The treated white water is used to clean the screen on the main body 1, thereby avoiding water waste. At the same time, through the cooperation of the outlet pipe 4 and the conveying pipe 6, the water source is sprayed out through the adjustable rotary nozzle 8 to clean the screen. The adjustable rotary nozzle 8 is a four-hole rotary nozzle in the prior art, which has the function of speed adjustment. When cleaning the screen, by adjusting the spray rate and pressure of the adjustable rotary nozzle 8 to a suitable force, even if the adjustable rotary nozzle 8 is equipped with a protective component 9, it can still clean the screen.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
