Description

Technical Field

[0001] This utility model relates to the field of sampling and dilution technology, and more specifically, to an industrial slurry sampling and dilution device. Background Technology

[0002] Industrial pulp is a suspension or paste formed by mixing solid particles (or powders) with a liquid medium in industrial production. It is widely used in papermaking, textiles, coatings, ceramics, mining, food processing, and other fields. Its composition and form vary greatly depending on its application. For example: In the papermaking industry, pulp is made by mixing plant fibers (such as wood pulp and straw pulp) with water and is used for paper forming; in the textile industry, pulp may be a mixture of starch, polyvinyl alcohol (PVA), etc., with water and is used for sizing yarn to enhance its abrasion resistance; in the mining industry, ore is crushed and mixed with water to form pulp, which facilitates transportation and subsequent beneficiation.

[0003] Currently, high-concentration slurries contain densely packed solid particles, making it difficult to directly observe their morphology (e.g., severe agglomeration under a microscope). They are also difficult to separate from the liquid during subsequent operations such as filtration and centrifugation, hindering subsequent analysis. Therefore, an industrial slurry sampling and dilution device is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an industrial slurry sampling and dilution device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an industrial slurry sampling and dilution device, including a cabinet, on which a dilution component is provided;

[0006] The dilution assembly includes an inner lining frame disposed within a cabinet, an inner lining frame having a material dispensing tank inside, a filter for filtering the material on one side of the material dispensing tank, and a pump for extracting the material on one side of the filter.

[0007] A dilution tank is provided at the top of the inner cavity of the material receiving tank.

[0008] Optionally, in a possible implementation, the filter is connected to the material receiving tank via a conduit, and the input end of the pump is connected to the filter via a conduit. A connecting valve is provided on the top of the filter, and the output end of the pump is connected to the connecting valve via a conduit. The connecting valve is connected to the dilution tank via a conduit. A vibration motor is provided on one side of the dilution tank. The vibration motor is bolted to the inner wall of the material receiving tank. A cabinet door is provided on the outside of the cabinet body. The cabinet door is hinged to the cabinet body via a hinge. A sealing sleeve is provided on the outside of the cabinet door. A control panel is embedded in the cabinet door.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] By incorporating a filter, the device effectively intercepts solid particles or agglomerates in high-concentration slurries, preventing such impurities from entering subsequent dilution and analysis stages. Simultaneously, the pump and connecting valve's reflux design allows the slurry to be returned to the filter for secondary filtration at the pump output, further enhancing the filtration effect and ensuring that the diluted slurry is free of interfering impurities. This provides impurity-free samples for subsequent microscopic morphology observation, filtration-centrifugation separation, and other analytical operations, resolving the problem of impurities causing analytical result deviations in existing technologies.

[0011] A vibration motor installed on one side of the dilution tank can drive the tank to shake synchronously, breaking up the particle agglomeration structure in the slurry and enabling the slurry and diluent to mix quickly and evenly. Compared with traditional manual stirring or static mixing, this design can avoid problems such as insufficient dilution in certain areas and uneven dilution caused by the sedimentation of solid particles, ensuring that the concentration of the diluted slurry is consistent and meets the stringent requirements of subsequent analysis.

[0019] This embodiment discloses an industrial slurry sampling and dilution device, which aims to solve the technical problems of existing high-concentration industrial slurries, which are difficult to observe in terms of morphology due to the dense solid particles, and are inconvenient for subsequent separation and analysis.

[0020] Cabinet 1: Can be made of welded stainless steel sheet, with internal space reserved for the installation of dilution components.

[0021] Inner lining frame 2: Fixed to the bottom surface inside cabinet 1 by bolts, its inner cavity dimensions are adapted to the outer wall of material receiving tank 3, used for positioning and buffering material receiving tank 3, as shown in the attached figure. Figure 1 Appendix Figure 4 As shown. Function: To prevent the material handling tank 3 from directly contacting the metal cabinet 1 and causing wear, and at the same time to reduce the vibration transmitted to the cabinet 1 when the vibration motor 8 is working.

[0022] Feeding tank 3: The inner wall of the tank is smooth and the bottom is sloped towards the feed inlet of filter 4 to facilitate slurry collection; the top of the feeding tank 3 has an opening for adding slurry to be treated, and the outer wall can be equipped with scale lines for observing the remaining slurry level, as shown in the attached figure. Figure 1 Appendix Figure 2 As shown. Used for temporary storage of industrial slurry to be sampled and diluted; the transparent material allows operators to easily observe the initial state of the slurry.

[0023] Filter 4: An industrial-grade basket filter, model SBL-20, can be selected. Filter 4 is connected to the bottom outlet of the feed tank 3 via a PU material conduit, with clamp-type connectors sealing both ends of the conduit. Filter 4 has an integrated connecting valve 7 at the top and a drain port at the bottom for periodically cleaning impurities trapped in the filter element. It is used to filter large particles or agglomerates in the slurry, preventing clogging of the subsequent pump 5 and ensuring that impurities remain in the diluted slurry to interfere with analysis.

[0024] Pump 5: A corrosion-resistant miniature diaphragm pump, model DBY-10, can be selected. The input end of pump 5 is connected to the outlet of filter 4 through a PU conduit, and the output end is connected to the inlet of connecting valve 7 through a PU conduit. The bottom of pump 5 is fixed to the inner liner frame 2 with shock-absorbing pads to reduce vibration and noise during operation. As a power source, it draws slurry from the material tank 3, filters it through filter 4, and then transports it to the dilution tank 6, or draws cleaning fluid to flush the pipeline during the cleaning stage.

[0025] Connecting valve 7: A 2W-160-15 two-position three-way solenoid valve can be selected. The common end of connecting valve 7 is connected to the output end of pump 5, the first outlet end is connected to the top inlet of dilution tank 6 through a PU conduit, and the second outlet end is connected to the top return port of filter 4 through a PU conduit. Connecting valve 7 is connected to the controller inside cabinet 1 through a wire, and the power on / off state is controlled by control panel 11. When switching the slurry flow direction, when powered on, the common end is connected to the first outlet end, and the slurry is delivered to dilution tank 6; when powered off, the common end is connected to the second outlet end, and the slurry flows back to filter 4 for secondary filtration.

[0026] Diluting tank 6: Made of welded stainless steel, it has an inlet at the top connected to valve 7 and a diluent addition port, and an outlet at the bottom for discharging the diluted slurry. (See attached image) Figure 1 Appendix Figure 2 As shown, it is used to contain slurry and diluent, achieve mixing and dilution, and polish the inner wall to avoid slurry residue.

[0027] Vibration motor 8: A small horizontal vibration motor of model YZU-5-4 can be selected. The vibration motor 8 is fixed to the inner wall of the feeding tank 3 by bolts. It drives the dilution tank 6 to vibrate synchronously through high-frequency vibration, breaking up the particle agglomerates in the slurry, so that the slurry and diluent, such as water and solvent, are quickly and evenly mixed, avoiding uneven dilution caused by the sedimentation of solid particles.

[0028] Cabinet door 9 and sealing sleeve 10: Cabinet door 9 is made of stainless steel and is hinged to cabinet body 1 via hinge 12; sealing sleeve 10 is a custom rectangular silicone sealing ring, which is fixed to the inner edge of cabinet door 9 via a slot, as shown in the attached document. Figure 1 Appendix Figure 3 As shown, the cabinet door 9 is used to open or close the cabinet body 1 to protect the internal components; the sealing sleeve 10 fits tightly against the edge of the opening of the cabinet body 1 when the cabinet door 9 is closed to prevent the leakage of odor from the slurry volatilization, while also preventing external dust from entering.

[0029] Control panel 11: An industrial touch screen of model TK6071IP can be selected. It can control the start and stop of pump 5 and flow regulation, start and stop of vibration motor 8 and frequency regulation, and power on / off control of connecting valve 7 and dilution tank discharge valve through control command input.

[0030] Operating parameters display: Real-time display of pump flow rate, vibration frequency, slurry temperature in the dilution tank (detected by a PT100 temperature sensor pre-embedded in the tank), and equipment operating time. Connected to pump 5, vibration motor 8, connecting valve 7, temperature sensor, and control panel 11 via wires; Function: Receives commands from control panel 11, drives each electrical component to operate according to preset logic, and simultaneously collects sensor data and feeds it back to control panel 11;

[0031] The specific working principle is as follows: the staff starts the device initialization program through the control panel 11, the PLC controls the connection valve 7 to be de-energized and the discharge valve of the dilution tank 6 to be closed.

[0032] Open cabinet door 9 and pour the pulp to be processed into the top opening of feed tank 3 until the pulp level reaches the scale line of feed tank 3. Then close cabinet door 9 and seal cabinet 10 to seal cabinet body 1.

[0033] The pump 5 is started by the control panel 11. The pulp in the feed tank 3 is drawn by the suction of the pump 5 and collected at the bottom inclined slope to the feed port of the filter 4. The filtered pulp is transported by the pump 5 to the connecting valve 7. When the connecting valve 7 is de-energized, the pulp flows back to the top of the filter 4 through the second outlet end to achieve secondary filtration.

[0034] After the secondary filtration is completed, the control panel 11 prompts "Add diluent". The operator opens the diluent addition valve on the top of the dilution tank 6, adds deionized water, and then closes the valve.

[0035] The operating frequency of the vibration motor 8 is set by the control panel 11, the PLC controls the connection valve 7 to be energized, the pump 5 continues to run, and the filtered pulp is transported to the dilution tank 6 until the pulp in the feed tank 3 is completely transported, and the pump 5 stops.

[0036] High-frequency vibration drives the dilution tank 6 to vibrate, rapidly mixing the pulp with deionized water.

[0037] The operator clicks the "Sampling" button on the control panel 11, and the PLC controls the discharge valve of the dilution tank 6 to be energized and opened. The diluted pulp flows out from the bottom discharge port and is used for subsequent microscopic morphological observation and composition analysis.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
