Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and in particular relates to a fineness detection sampling device for the grinding process. Background Technology

[0002] Coating manufacturing is an industrial production activity that uses natural or synthetic resins as the main component, adding pigments, solvents, and auxiliary materials to process and produce covering materials. It encompasses the preparation of products such as waterproof coatings and insulating varnishes, as well as auxiliary materials such as thinners. Its core processes include the preparation of film-forming substances, the grinding and dispersion of color pastes, and paint mixing and color matching.

[0003] During the grinding and dispersion process of pigment paste, it is necessary to test the fineness to determine whether the product meets the quality requirements. Therefore, it is necessary to use sampling equipment to sample and analyze the coating. In some open processing equipment, the equipment is usually directly inserted into the solution during the processing to collect the solution for corresponding data analysis. However, there are differences in the uniformity of samples collected at different depths during the stirring and dispersion process. Although the existing equipment can set corresponding sampling ports at different depths, the open sampling port will be filled with the upper layer of solution in advance during the insertion process, resulting in insufficient uniformity of the sample.

[0026] This utility model embodiment provides a fineness detection and sampling device for the grinding process, such as... Figures 1-6 As shown, the fineness detection and sampling device for the grinding process includes:

[0027] The sampling cylinder 100 includes a cylinder body 110 and a counterweight 120 located at the end of the cylinder body 110. The top is provided with an arc-shaped guide groove 102. The infusion tube 130 extends into the cylinder body 110. The side wall of the sampling cylinder 100 is provided with a feed inlet 101. The sampling cylinder 100 is provided with an infusion tube 130 for connecting to a hydraulic pump.

[0028] The gate component 200 includes an outer rotating ring 210, a closing module, and a connecting rod 230. The closing module includes two sets of parallel supporting rings 220 and a sealing plate 240 located between the supporting rings 220. The sealing plate 240 is attached to the inner wall of the sampling cylinder 100. The gate component 200 closes the feed inlet 101 during rotation.

[0029] The outer rotating ring 210 and the support ring 220 are connected by a connecting rod 230. The outer rotating ring 210 of the support ring 220 is located on the outside of the sampling cylinder 100. The connecting rod 230 extends from the top of the sampling cylinder 100 to the inside of the sampling cylinder 100 through the guide groove 102, and is used to drive the closed module to rotate. The top of the sampling cylinder 100 must not be submerged in the solution.

[0030] The sampling cylinder 100 is manually placed into the grinding equipment that is in operation. The grinding equipment in this application is mainly used in hydraulic lifting basket type grinding machines. The liquid in the grinding machine is mixed through the sampling cylinder 100 of this application, and the components in the mixed liquid are analyzed to ensure that the product produced by the mixed liquid meets the corresponding quality requirements. The sampling cylinder 100 is quickly submerged below the liquid surface under the action of the configuration block 120, and the sampling cylinder 100 is opened as the gate component 200 rotates, allowing the sample in the mixing area to enter along the feed port 101 on the side wall of the sampling cylinder 100. Here, the feed port 101 is arranged and distributed along the axial direction of the sampling cylinder 100, and the feed port 101 can obtain solutions at different depths.

[0031] The sampling cylinder 100 includes a cylinder 110 and a counterweight 120 located at the end of the cylinder 110. The top is provided with an arc-shaped guide groove 102. The end area of ​​the cylinder 110 away from the top is the extraction area. The infusion tube 130 extends into the extraction area inside the cylinder 110. The infusion tube 130 is connected to an external liquid pump. When the solution enters through the inlet 101, it will reach the extraction area along the side wall.

[0032] A small amount of paint is manually placed into the grinding equipment in operation through the sampling cylinder 100 and sucked in through the inlet 101. The liquid pump will first extract the first portion of the extracted liquid and select the solution from the later stages. As the gate 200 rotates and opens, solutions at different depths will enter the cylinder 110. It should be noted that the extraction speed of the liquid pump should be much greater than the entry speed of the inlet 101. In this way, solutions at different depths can reach the extraction area. Considering the pressure and extraction depth, the size of the inlet 101 closer to the bottom of the grinding equipment is smaller. The feeding area is used to keep the liquid volume at different depths relatively close.

[0033] This application utilizes a sampling cylinder 100 to sample the sample. Under the sealing effect of the gate component 200, excessive upper solution is prevented from entering the sampling cylinder 100 during the lowering process, which could cause the sampling cylinder 100 to fill prematurely and result in inaccurate sampling data. At the same time, inlets 101 of different sizes are set at different depths to keep the inflow rate of the solution at different depths as close as possible, ensuring the uniformity of sampling. The liquid pump here uses existing technology to extract the sample solution, and the outlet pipe connected to the rear end outputs the sample for testing.

[0034] In a preferred embodiment of this invention, the sealing plate 240 adopts a rectangular structure, and the size of the sealing plate 240 is larger than the size of the largest set of feed inlets 101. As the gate component 200 rotates, the sealing plate 240 rotates to the feed inlet 101 and blocks the feed inlet 101.

[0035] In this application, the sealing plate 240 blocks the feed inlet 101 to reduce the amount of solution entering. The purpose here is to prevent the rapid influx during the lowering process from increasing the difficulty of the subsequent extraction work. By blocking the sample tube 100, the amount that has seeped in before can be quickly cleared, so that the later sample is less likely to mix with a large amount of the upper layer solution that has flowed in before.

[0036] In a further preferred embodiment of this utility model, the number of closed modules is at least three, the number of inlets 101 is at least six, and the three groups are arranged in a unit. The inlets 101 of different units are symmetrically distributed, and the interval between the inlets 101 is the same as the spacing between different closed modules.

[0037] In this embodiment, the number of sealing plates 240 in the closed module is two sets, and the two sets of sealing plates 240 are symmetrically arranged on both sides of the closed module. The guide groove 102 adopts a ring structure to restrict the rotation angle of the gate component 200. The sampling cylinder 100 is also provided with a limiting ring 250 and a bottom support ring 260. The limiting ring 250 and the bottom support ring 260 restrict the axial movement of the gate component 200. The area where the bottom support ring 260 is located and the bottom of the sampling cylinder 100 is the extraction area.

[0038] During the insertion of the sampling cylinder 100, the gate component 200 needs to close the feed inlet 101. As the counterweight 120 contacts the bottom of the grinding equipment, the gate component 200 is rotated to fully open the feed inlet 101, allowing the solution to enter the sampling cylinder 100 in batches. The liquid pump will promptly deliver the solution accumulated in the extraction area. Usually, the initial sample solution is discarded, and the solution discharged in the middle section is intercepted. After the sampling work is completed, the liquid pump is turned off, and the sampling cylinder 100 is lifted. At this time, the gate component 200 does not need to be closed, allowing the feed inlet 101 to discharge as much solution as possible from the cylinder. Finally, the solution in the extraction area can be discharged from the feed inlet 101 by the liquid pump in conjunction with the tilting method, or a discharge valve can be set on the bottom side wall of the sampling cylinder 100 to achieve discharge.
