Description

Technical Field

[0001] The present invention relates to a filter screen and its usage method, in particular to a foreign object filter screen for a pulp chest and its usage method, belonging to the technical field of pulp manufacturing equipment. Background Art

[0002] Pulp is a fibrous substance made from plant fibers by different processing methods. The quality of pulp mainly depends on its fiber morphology and the purity of the fibers.

[0003] Therefore, during the production process of pulp, it is necessary to filter the pulp. However, traditional filter screens do not have a certain oscillation function and can only be oscillated by an external vibrator. The purpose of oscillation is, on the one hand, to improve the filtration efficiency, and on the other hand, to prevent the pulp from blocking the filter screen. Without an oscillation structure, a large amount of manpower and material resources will be wasted later, and the filtration efficiency will be greatly reduced.

[0004] Therefore, it is urgent to improve the foreign object filter screen for the pulp chest to solve the above existing problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a foreign object filter screen for a pulp chest and its usage method. During the rotation of the double-output shaft motor, the special-shaped push wheel drives the brake convex surface to move up and down and squeeze the driven convex surface, causing the oscillation plate to rotate around the vibration plate connecting piece. During the rotation of the oscillation plate, it can drive the pulp to shake, improve the flow rate, and at the same time accelerate the filtration efficiency to avoid blocking the filter screen.

[0006] To achieve the above purpose, the main technical solutions adopted by the present invention include:

[0007] A foreign object filter screen for a pulp chest, including a filter screen body. A brake component box is fixedly arranged in the middle of the filter screen body. Symmetrically distributed filter grooves are opened on both sides of the brake component box, and a filter screen is fixedly arranged inside the filter grooves;

[0008] A brake component is fixedly arranged inside the brake component box. The brake component includes a double-output shaft motor and a pushing member. A brake convex surface is fixedly arranged on one side of the upper end of the pushing member. Stirring blade fixing plates are fixedly arranged at both ends of the filter screen body. A stirring blade rotating connecting piece is arranged on one side of the stirring blade fixing plates. An oscillation plate is rotatably arranged on the inner side surface of the stirring blade rotating connecting piece. A driven convex surface is fixedly arranged on one side surface of the oscillation plate. The driven convex surface abuts against the brake convex surface. The brake convex surface is used to vertically push the driven convex surface. The angle of rotation of the oscillation plate around the vibration plate connecting piece is 0 to 30°.

[0009] Through the above technical solution, the traditional filter screen does not have a certain oscillation function and can only be oscillated by an external vibrator. The purpose of the oscillation is, on the one hand, to improve the filtration efficiency, and on the other hand, to prevent the pulp from clogging the filter screen. By starting the braking component inside the braking component box, during the rotation of the double-output shaft motor on the braking component, the double-output shaft motor drives the rotation of the special-shaped driving wheel through the horizontal connecting rod, and the special-shaped driving wheel drives the up-and-down movement of the braking convex surface. When the braking convex surface moves upward, the driven convex surface does not rotate under the action of gravity. When the braking convex surface moves downward, the braking convex surface squeezes the driven convex surface, causing the oscillating plate to rotate around the vibrating plate connecting piece. During the rotation of the oscillating plate, it can drive the fluctuation of water, so that the pulp can be shaken, improving the flow rate and accelerating the filtration efficiency at the same time.

[0010] Preferably, a braking chamber is provided inside the braking component box. The double-output shaft motor is fixedly arranged in the middle of the braking chamber. Output shafts at both ends of the double-output shaft motor are connected with horizontal connecting rods. One end of the horizontal connecting rod far away from the double-output shaft motor is connected with a special-shaped driving wheel. One end of the special-shaped driving wheel far away from the central axis is rotationally connected with the driving piece through a rivet connecting piece. The driving piece penetrates through the braking component box and extends into the inside of the stirring blade fixing plate. The braking convex surface corresponds to the driven convex surface. Among them, when the braking convex surface brakes downward, the oscillating plate rotates.

[0011] Through the above technical solution, during the rotation of the double-output shaft motor on the braking component, the double-output shaft motor drives the rotation of the special-shaped driving wheel through the horizontal connecting rod, and the special-shaped driving wheel drives the up-and-down movement of the braking convex surface. When the braking convex surface moves upward, the driven convex surface returns to its original state under the action of gravity. When the braking convex surface moves downward, the braking convex surface squeezes the driven convex surface, causing the oscillating plate to rotate around the vibrating plate connecting piece. Therefore, the pulp can be shaken, improving the flow rate and accelerating the filtration efficiency at the same time.

[0012] Preferably, symmetrically distributed support plates are arranged at the bottom of the filter screen body. A component chamber is provided inside one of the support plates. A central processor is fixedly arranged inside the component chamber. A sealing cover is fixedly arranged on the component chamber. The sealing cover is used to seal the component chamber. The inner side surface of the support plate is connected with a plurality of uniformly distributed heating detection components through a tensile sensor. The tensile sensor establishes a communication connection with the central processor. The central processor is electrically connected to an external power supply through an insulated wire.

[0013] Through the above technical solution, symmetrically distributed support plates are provided at the bottom of the filter net body, and a central processing unit is arranged inside the support plates. The central processing unit is fixedly arranged inside the filter net body. The filter net body can be applied to various different containers without being restricted by the environment, so the scope of use is greatly improved.

[0014] Preferably, a steel wire rope is connected inside the heating detection component, and an insulating layer is arranged outside the heating detection component. A heat-resistant layer and a heating coil are arranged between the insulating layer and the steel wire rope. Both the heat-resistant layer and the heating coil are communicatively connected to the central processing unit through wires. The heating detection component is connected to a tensile sensor. Therefore, the heating detection component can be used to detect whether there are large-particle impurities in the pulp solution and can also be used to heat the pulp solution. The structure is simple. Since the heating detection component occupies a relatively large space area, the pulp solution can be rapidly heated in a short time, greatly improving the heating efficiency. The steel wire rope can prevent the heating detection component from being pulled apart and improve the structural strength of the heating detection component. The insulating layer plays a certain insulating role, and the heat-resistant layer conducts heat insulation to improve the safety of use.

[0015] Preferably, a temperature sensor and a flow rate sensor are fixedly arranged on the upper side surface of the braking component box. Both the temperature sensor and the flow rate sensor are communicatively connected to the central processing unit through wires. The temperature sensor is a thermocouple temperature sensor, and the model of the flow rate sensor is YF-S201 YF-S201. When the temperature sensor detects that the temperature inside the pulp is relatively low, it sends a signal to the central processing unit, and the central processing unit then sends the information to the heating coil, and the heating coil starts to heat the pulp solution, with a high degree of automation and greatly improving the detection efficiency.

[0016] Preferably, a red lamp bead and a bubble generator are arranged on one side of the flow rate sensor. Both the red lamp bead and the bubble generator are communicatively connected to the central processing unit through wires. The model of the tensile sensor is NCYY12-TS04. A number of heating detection components are connected between the support plates. Under normal circumstances, the impact force of the fine pulp pair is within a certain range. If there are relatively large impurities in the pulp, then the impact force of the impurities on the heating detection component will increase, and the tensile sensor can detect the force of the heating detection component and transmit the information to the central processing unit.

[0017] Preferably, magnet bins are provided on both side surfaces of the braking component box, and magnets are fixedly arranged inside the magnet bins. The magnets are arranged inside the filter tank. When the pulp is flowing, metals such as iron in the pulp can be directly adsorbed on the magnets, improving the quality of the pulp.

[0018] A method for using a foreign object filter for a pulp chest, which includes the following steps:

[0019] Step 1: Filter screen installation. Place the filter screen body at the bottom of the container where it needs to be installed, and establish a communication connection between the filter screen body and an external power source through an insulated wire;

[0020] Step 2: Filtration. Use the filter screen on the filter tank to filter the pulp;

[0021] Step 3: Pulp evaluation. Use the heating detection component at the bottom of the filter screen body to detect the collision of the pulp, detect the temperature of the pulp through a temperature sensor, and detect the flow rate of the pulp through a flow rate sensor.

[0022] Preferably, the specific process of the filtration includes:

[0023] Filter the pulp through the filter screen on the filter tank. During the filtration process, start the double-output shaft motor on the braking component to drive the rotation of the horizontal connecting rod. The rotation of the horizontal connecting rod drives the rotation of the special-shaped driving wheel. The special-shaped driving wheel pulls the braking convex surface on the driving part up and down, causing the oscillating plate to rotate cyclically around the vibrating plate connecting piece.

[0024] Preferably, the pulp evaluation in Step 3 includes detection and evaluation;

[0025] The detection is specifically: Detect the force of the collision of the heating detection component in the pulp through a tension sensor, and transmit the information to the central processing unit. The temperature sensor and the flow rate sensor transmit the pulp temperature and flow rate data to the central processing unit;

[0026] The evaluation is specifically: When the tension sensor detects a relatively large collision force of the heating detection component, it transmits the information to the central processing unit, and the central processing unit transmits the information to the red lamp bead and the bubble generator;

[0027] The temperature sensor sends the detection information to the central processing unit, and the central processing unit processes the information and then sends the information to the heating coil.

[0028] The present invention has at least the following beneficial effects:

[0029] 1. During the rotation of the double-output shaft motor, the special-shaped driving wheel drives the braking convex surface to move up and down and squeeze the driven convex surface, causing the oscillating plate to rotate around the vibrating plate connecting piece. During the rotation of the oscillating plate, it can drive the pulp to shake, improve the flow rate and accelerate the filtration efficiency to avoid clogging of the filter screen.

[0030] 2. The heating detection component is connected to the tensile sensor. Therefore, the heating detection component can be used to detect whether there are large-particle impurities in the pulp solution and can also be used to heat the pulp solution. The structure is simple. Since the space area occupied by the heating detection component is relatively large, the pulp solution can be rapidly heated in a short time, greatly improving the heating efficiency. The steel wire rope can prevent the heating detection component from being pulled apart and enhance the structural strength of the heating detection component. The insulating layer plays a certain insulating role, and the heat-resistant layer provides heat insulation to enhance the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0041] The following will elaborate on the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0042] As Figures 1-8 shown, the foreign object filter screen for the pulp chest provided in this embodiment includes a filter screen body 1. A brake component box 102 is fixedly arranged in the middle of the filter screen body 1. Symmetrically distributed filter tanks 101 are opened on both sides of the brake component box 102. A filter screen 7 is fixedly arranged inside the filter tank 101;

[0043] A brake component 2 is fixedly arranged inside the brake component box 102. The brake component 2 includes a double-output shaft motor 201 and a pushing piece 205. A brake convex surface 206 is fixedly arranged on one side surface of the upper end of the pushing piece 205. Stirring blade fixing plates 103 are fixedly arranged at both ends of the filter screen body 1. A stirring blade rotating connecting piece 106 is arranged on one side of 103. An oscillating plate 3 is rotatably arranged on the inner side surface of the stirring blade rotating connecting piece 106. A driven convex surface 301 is fixedly arranged on one side surface of the oscillating plate 3. The driven convex surface 301 abuts against the brake convex surface 206. The brake convex surface 206 is used for vertically pushing the driven convex surface 301. The angle at which the oscillating plate 3 rotates around the vibrating plate connecting piece 302 is from 0 to 30°;

[0044] Traditional filter screens do not have a certain oscillation function and can only be oscillated by an external vibrator. The purpose of oscillation is, on the one hand, to improve the filtration efficiency, and on the other hand, to prevent the filter screen from being blocked by pulp. By starting the braking component 2 inside the braking component box 102, during the rotation of the double-output shaft motor 201 on the braking component 2, the double-output shaft motor 201 drives the rotation of the special-shaped driving wheel 203 through the horizontal connecting rod 202. The special-shaped driving wheel 203 drives the up-and-down movement of the braking convex surface 206. When the braking convex surface 206 moves upward, the driven convex surface 301 does not rotate under the action of gravity. When the braking convex surface 206 moves downward, the braking convex surface 206 squeezes the driven convex surface 301, causing the oscillation plate 3 to rotate around the vibration plate connecting piece 302. During the rotation of the oscillation plate 3, it can drive the fluctuation of water, so that the pulp can be shaken, improving the flow rate and accelerating the filtration efficiency at the same time.

[0045] In this embodiment, as Figure 1 and Figure 3 shown, a braking chamber 105 is provided inside the braking component box 102. The double-output shaft motor 201 is fixedly arranged in the middle of the braking chamber 105. Output shafts at both ends of the double-output shaft motor 201 are connected with horizontal connecting rods 202. One end of the horizontal connecting rod 202 away from the double-output shaft motor 201 is connected with a special-shaped driving wheel 203. One end of the special-shaped driving wheel 203 away from the central axis is rotationally connected with a driving piece 205 through a rivet connecting piece 204. The driving piece 205 penetrates through the braking component box 102 and extends into the inside of the stirring blade fixing plate 103. The braking convex surface 206 corresponds to the driven convex surface 301. Among them, when the braking convex surface 206 brakes downward, the oscillation plate 3 rotates;

[0046] During the rotation of the double-output shaft motor 201 on the braking component 2, the double-output shaft motor 201 drives the rotation of the special-shaped driving wheel 203 through the horizontal connecting rod 202. The special-shaped driving wheel 203 drives the up-and-down movement of the braking convex surface 206. When the braking convex surface 206 moves upward, the driven convex surface 301 returns to its original state under the action of gravity. When the braking convex surface 206 moves downward, the braking convex surface 206 squeezes the driven convex surface 301, causing the oscillation plate 3 to rotate around the vibration plate connecting piece 302. Therefore, the pulp can be shaken, improving the flow rate and accelerating the filtration efficiency at the same time.

[0047] In this embodiment, as Figure 1 、 Figure 2 and Figure 5As shown in the figure, symmetrically distributed support plates 104 are provided at the bottom of the filter screen body 1. An electronic component bin 107 is provided inside one of the support plates 104. A central processing unit 6 is fixedly arranged inside the electronic component bin 107. A sealing cover 12 is fixedly arranged on the electronic component bin 107. The sealing cover 12 is used to seal the electronic component bin 107. The inner side surface of the support plate 104 is connected with a plurality of uniformly distributed heating detection components 4 through a tension sensor 5. The tension sensor 5 is communicatively connected with the central processing unit 6. The central processing unit 6 is electrically connected to an external power supply through an insulated wire 13.

[0048] Symmetrically distributed support plates 104 are provided at the bottom of the filter screen body 1. A central processing unit 6 is arranged inside the support plate 104. The central processing unit 6 is fixedly arranged inside the filter screen body 1. The filter screen body 1 can be applied to various different containers without being restricted by the environment. Therefore, the scope of use is greatly improved.

[0049] Among them, the model of the tension sensor 5 is NCYY12-TS04. A plurality of heating detection components 4 are connected between the support plates 104. Under normal circumstances, the impact force of the fine pulp pair is within a certain range. If there are large impurities in the pulp, then the impact force of the impurities on the heating detection components 4 will increase. The tension sensor 5 can detect the force of the heating detection components 4 and transmit the information to the central processing unit 6.

[0050] Furthermore, a red light bead 10 and a bubble generator 11 are arranged on one side of the flow rate sensor 9. Both the red light bead 10 and the bubble generator 11 are communicatively connected with the central processing unit 6 through wires. The central processing unit 6 sends signals to the red light bead 10 and the bubble generator 11. The red light bead 10 emits visible light into the pulp solution. At the same time, bubbles are generated in the pulp solution through the bubble generator 11. Therefore, tiny phenomena that cannot be recognized by the naked eye can be displayed through light and bubbles, which is convenient for observation and greatly improves the convenience of use.

[0051] A temperature sensor 8 and a flow rate sensor 9 are fixedly arranged on the upper side surface of the braking component box 102. Both the temperature sensor 8 and the flow rate sensor 9 are communicatively connected with the central processing unit 6 through wires.

[0052] Among them, the temperature sensor 8 is a thermocouple temperature sensor. The model of the flow rate sensor 9 is YF-S201YF-S201. When the temperature sensor 8 detects that the temperature inside the pulp is low, it sends a signal to the central processing unit 6. The central processing unit 6 then sends the information to the heating coil 403. The heating coil 403 then starts to heat the pulp solution, with a high degree of automation and greatly improving the detection efficiency.

[0053] In this embodiment, as Figure 4As shown, a steel wire rope 404 is internally connected to the heating detection component 4. An insulating layer 401 is provided outside the heating detection component 4. A heat-resistant layer 402 and a heating coil 403 are provided between the insulating layer 401 and the steel wire rope 404. Both the heat-resistant layer 402 and the heating coil 403 are communicatively connected to the central processor 6 through wires.

[0054] The heating detection component 4 is connected to the tensile sensor 5. Therefore, the heating detection component 4 can be used to detect whether there are large-particle impurities in the pulp solution and can also be used to heat the pulp solution. The structure is simple. Since the heating detection component 4 occupies a relatively large space area, the pulp solution can be quickly heated in a short time, greatly improving the heating efficiency. The steel wire rope 404 can prevent the heating detection component 4 from being pulled apart and enhance the structural strength of the heating detection component 4. The insulating layer 401 plays a certain insulating role, and the heat-resistant layer 402 provides heat insulation to enhance the safety of use.

[0055] In this embodiment, as Figure 1 shown, magnet bins 108 are provided on both side surfaces of the brake component box 102. Magnets 14 are fixedly provided inside the magnet bins 108. The magnets 14 are arranged inside the filter tank 101. When the pulp flows, metals such as iron in the pulp can be directly adsorbed on the magnets 14, improving the quality of the pulp.

[0056] As Figures 1-8 shown, the method of using the foreign object filter for the pulp chest provided in this embodiment includes the following steps:

[0057] Step 1: Filter screen installation. Place the filter screen body 1 at the bottom of the container to be installed, and communicatively connect the filter screen body 1 to an external power source through the insulating wire 13.

[0058] Step 2: Filtration. Use the filter screen 7 on the filter tank 101 to filter the pulp.

[0059] Step 3: Pulp evaluation. Use the heating detection component 4 at the bottom of the filter screen body 1 to detect the collision of the pulp, use the temperature sensor 8 to detect the temperature of the pulp, and use the flow rate sensor 9 to detect the flow rate of the pulp.

[0060] The specific process of filtration includes:

[0061] Filter the pulp through the filter screen 7 on the filter tank 101. During the filtration process, start the double-output shaft motor 201 on the brake component 2 to drive the rotation of the horizontal connecting rod 202. The rotation of the horizontal connecting rod 202 drives the rotation of the special-shaped driving wheel 203. The special-shaped driving wheel 203 pulls the braking convex surface 206 on the driving member 205 up and down, causing the oscillating plate 3 to rotate cyclically around the vibration plate connecting member 302.

[0062] The pulp evaluation in Step 3 includes detection and assessment;

[0063] Specifically, the detection is as follows: The force sensor 5 detects the force of the heating detection component 4 being collided in the pulp and transmits the information to the central processor 6. The temperature sensor 8 and the flow rate sensor 9 transmit the pulp temperature and flow rate data to the central processor 6;

[0064] Specifically, the assessment is as follows: When the force sensor 5 detects a relatively large collision force of the heating detection component 4, it transmits the information to the central processor 6, and the central processor 6 transmits the information to the red light bead 10 and the bubble generator 11;

[0065] The temperature sensor 8 sends the detection information to the central processor 6, and after the central processor 6 processes the information, it sends the information to the heating coil 403.

[0066] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but rather use the difference in functions of the components as the criterion for distinction.
