[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a low-consistency cleaner for pulp production provided by the utility model; Figure 2 for Figure 1 A low-consistency cleaner for pulp production comprises:

[0025] Two mounting frames 1, a first pipe 2 is connected to the top between the two mounting frames 1, and a rectangular connecting frame 3 is connected to the surface of the first pipe 2;

[0026] A second pipeline 4, the second pipeline 4 is installed on the surface of the rectangular connecting frame 3, and a third pipeline 5 and a fourth pipeline 6 are sequentially arranged between the two mounting frames 1 from top to bottom;

[0027] A plurality of through holes 9, wherein the plurality of through holes 9 are respectively opened on the surface of the first pipe 2 and the second pipe 4;

[0028] A plurality of connectors 7 are respectively installed on the third pipe 6 , and a plurality of mounting heads 8 are arranged on the surface of the fourth pipe 7 .

[0029] Both ends of the first pipeline 2 , the second pipeline 4 , the third pipeline 5 and the fourth pipeline 6 are connected with flanges 10 .

[0030] The first pipeline 2, the rectangular connecting frame 3 and the second pipeline 4 are installed in a superimposed manner, and the arc-shaped pipelines 11 inside the through holes 9 are installed in a staggered manner.

[0031] The flange 10 is used for installation of the first pipeline 2 , the second pipeline 4 , the third pipeline 5 and the fourth pipeline 5 .

[0032] Arc-shaped pipes 11 are installed inside the plurality of through holes 9 .

[0033] The plurality of connection heads 7 and the plurality of installation heads 8 are used to connect the connection pipes.

[0034] A plurality of fixing seats 12 are installed on the surface of the second pipe 4 .

[0035] The fixing seat 12 is used for the splicing of the device.

[0036] Slurry inlet: used for slurry to enter the remover, so that the slurry can enter the cylinder in a suitable way.

[0037] Cylinder: The main space that forms the vortex and provides a place for the separation of impurities and fibers.

[0038] Slag discharge port: Impurities are discharged from here to separate impurities from fibers.

[0039] Good pulp outlet: The separated fiber pulp flows out from here.

[0040] Conical part: helps to guide the discharge of impurities and the separation direction of fibers.

[0041] Pressure regulating device: can adjust the slurry pressure entering the cleaner to ensure separation effect and stable operation.

[0042] The slurry enters the cylinder of the cleaner from the tangential direction at a certain pressure and speed, forming a vortex in the cylinder. Due to the different specific gravities of impurities and fibers, the impurities are thrown to the cylinder wall under the action of centrifugal force, move downward along the cylinder wall, and finally discharged from the slag discharge port; while the fibers, due to their lighter specific gravity, move upward with the slurry in the center of the vortex and flow out from the good pulp outlet.

[0043] Some maintenance and care methods for low-concentration slag remover:

[0044] Regular cleaning: Clean the sediment and impurities inside the slag remover in time to prevent blockage.

[0045] Check the inlet and outlet slurry pipelines: ensure that the pipelines are unobstructed and free of damage, leakage, etc.

[0046] Check the seals: ensure that all sealing parts are in good condition to prevent leakage.

[0047] Monitor pressure: Pay attention to changes in inlet and outlet pressures, and promptly identify the causes if any abnormalities are detected.

[0048] Check the wear condition: Check the wear degree of the slag remover body and related parts regularly, and replace or repair them when necessary.

[0049] Keep the surrounding environment clean: prevent dust, debris, etc. from entering the slag remover and affecting its normal operation.

[0050] Operate in accordance with operating procedures: Correct operation can reduce the chance of equipment failure and damage.

[0051] Regular maintenance: including comprehensive inspection and maintenance of mechanical structure, control system, etc.

[0052] Lubricated parts: Regularly lubricate and maintain parts that require lubrication.

[0053] Train operators: Ensure operators are familiar with equipment performance and maintenance points.

[0054] The installation steps of low concentration cleaner are as follows:

[0055] Determine the installation location and size: According to the equipment requirements and actual site conditions, determine the installation location and size of the slag remover, and draw a basic diagram.

[0056] Installation foundation: According to the foundation drawing, carry out foundation construction at the installation site to ensure the stability and firmness of the foundation.

[0057] Assemble the slag remover: transport the various components of the slag remover to the installation site for assembly. Before assembly, carefully check whether the components are intact. If damaged, they need to be repaired before assembly.

[0058] Connecting pipelines: Use the union of the ball valve to connect the ball valve and the slag remover. When connecting, pay attention to wrapping the sealing tape around the threads of the inlet and outlet slurry pipes of the slag remover. The connection sequence is: first connect the double-union ball valve and the inlet and outlet slurry branch pipes. When connecting, pay attention to wrapping the sealing tape around the inlet and outlet slurry branch pipes and installing the sealing gasket at the union (slipknot) of the ball valve; then connect the ball valve and the slag remover.

[0059] Debugging and running: After completing all installations, conduct a comprehensive system inspection and debugging to ensure that the system operates normally.

[0060] The disassembly steps of the low-concentration cleaner are roughly the opposite of the installation steps. The specific steps are as follows:

[0061] Shut down the equipment: Before disassembling the cleaner, you need to shut down the equipment and cut off the power supply.

[0062] Dismantle the pipe connection: Dismantle the connection between the remover and the inlet and outlet slurry pipes in the reverse order of installation.

[0063] Removing the cleaner body: Use appropriate tools to remove the cleaner body from the installation location.

[0064] Cleaning and maintenance: After disassembly, clean and maintain the slag remover, check whether all parts are intact, and repair or replace any damage if necessary.

[0065] When installing and disassembling the low-concentration cleaner, the following points should be noted:

[0066] Safe operation: During installation and disassembly, pay attention to safety to avoid accidents.

[0067] Operate according to the instructions: Strictly follow the instructions of the equipment to ensure the correct installation and disassembly.
