Description

Technical Field

[0001] This utility model relates to the field of particle feeding equipment, and more specifically, to an online feeding device suitable for sampling and testing in production. Background Technology

[0002] Currently, most factories use screw conveyors to pick up materials during the production process, and then perform particle size testing. However, screw conveyors have difficulties in some situations, such as in environments with brittle particles, and can easily crush the particles. In addition, large clumps can block the production line, causing factory shutdowns and affecting production.

[0003] In summary, existing technologies are prone to clogging the pipes of the screw feeder or directly crushing the particles when processing brittle or large agglomerated particles, ultimately leading to inaccurate test results and failing to meet the testing procedures of the online particle size analyzer. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose an online sampling device suitable for sampling and testing in production.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An online material handling device suitable for sampling and testing in production includes an image particle size analyzer, and also includes a docking flange, mounting shell, through hole, horizontal screw, cylinder, nut, receiving box, baffle plate, and discharge funnel connected to the material feed chute of the particle production line.

[0007] The open mounting shell on the left is fixed to the docking flange, and the mounting shell has a through hole that faces the center hole of the docking flange. The center hole of the docking flange connects to the inside of the feed chute of the particle production line.

[0008] The horizontal screws are symmetrically welded to the mounting housing, and the horizontal screws correspond one-to-one with the mounting holes on the cylinder mounting seat and pass through the mounting holes. The cylinder's retraction rod extends through the through hole into the interior of the mounting housing.

[0009] The nut is threaded into the horizontal screw to ensure that the cylinder is horizontally positioned.

[0010] The receiving box is connected to the retraction rod of the cylinder, and a discharge port is opened on one side of the receiving box;

[0011] The baffle is installed on the docking flange by a fixing block, and one end of the baffle extends through the center hole of the docking flange into the material feed trough of the particle production line. The lower surface of the baffle is in contact with the upper surface of the receiving box.

[0012] The feed inlet of the discharge funnel is welded to and connected to the mounting shell, and the discharge outlet of the discharge funnel is connected to the image particle size analyzer through a pipeline.

[0013] Furthermore, the bottom surface of the receiving box is inclined and is higher on the left and lower on the right.

[0014] Furthermore, the receiving box is provided with an anti-stick coating.

[0015] Furthermore, the discharge funnel is inclinedly welded to the mounting shell and connected to the interior of the mounting shell, and the inlet of the discharge funnel is directly opposite the outlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Compared to existing technologies, this application uses a method of taking a cross-section of the material in the feed chute of the particle production line during material collection. This method can still complete material collection even when the particles are brittle or have agglomerates. During material collection, the receiving box is inserted into the feed chute, and after removal, the receiving box is no longer in the production line, thus avoiding any impact on the production line. At the same time, if there are large agglomerates in the material, they can be blocked by the material blocking baffle and cannot enter the receiving box (i.e., the material blocking baffle can control the area of ​​the feeding area in accordance with the actual amount of material entering the receiving box), thereby ensuring the accuracy, representativeness, repeatability, and stability of the test results.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0023] like Figure 1 and Figure 2As shown, an online material handling device suitable for sampling and testing in production includes an image particle size analyzer (which is prior art and not shown in the figure), a docking flange 1 (the particle production line material passage is not shown in the figure) connected to the particle production line material passage, a mounting shell 2, a through hole (not shown in the figure), a horizontal screw 3, a cylinder 4, a nut 5, a receiving box 6, a material blocking baffle 8, and a discharge funnel 9.

[0024] The left-side open mounting shell 2 is fixed on the docking flange 1, and the mounting shell 2 has a through hole facing the center hole of the docking flange 1. The center hole of the docking flange 1 is connected to the inside of the particle production line feed trough.

[0025] The horizontal screw 3 is symmetrically welded to the mounting shell 2, and the horizontal screw 3 corresponds one-to-one with the mounting holes on the cylinder 4 mounting seat and passes through the mounting holes (the mounting holes are not shown in the figure). The retraction rod of the cylinder 4 extends into the interior of the mounting shell 2 through the through hole.

[0026] Nut 5 is threadedly connected to horizontal screw 3 to ensure that cylinder 4 is horizontally positioned.

[0027] The receiving box 6 is connected to the retraction rod of the cylinder 4, and a discharge port 7 is provided on one side of the receiving box 6;

[0028] The baffle 8 is installed on the docking flange 1 by a fixing block (the fixing block is not labeled in the figure), and one end of the baffle 8 extends through the center hole of the docking flange 1 into the material feed trough of the particle production line. The lower surface of the baffle 8 is in contact with the upper surface of the receiving box 6 (specifically, the surface of the baffle 8 has a curvature to reduce the probability of residual adhesion of particles on the surface).

[0029] The inlet of the discharge funnel 9 is welded to and connected to the mounting shell 2, and the outlet of the discharge funnel 9 is connected to the image particle size analyzer through a pipeline.

[0030] In order to improve the flow of particles in the receiving box 6 and reduce the probability of them adhering to the receiving box 6, the above embodiment is further optimized by setting the inner bottom surface of the receiving box 6 at an angle with the left side higher than the right side, and providing an anti-stick coating on the receiving box 6.

[0031] To further improve the efficiency of pellet discharge, the above-described embodiment is further optimized by welding the discharge funnel 9 to the mounting shell 2 at an incline and connecting it to the interior of the mounting shell 2, with the inlet of the discharge funnel 9 facing the outlet 7.

[0032] The working process of this utility model:

[0033] After finding a suitable position on the feed trough of the particle production line, the docking flange 1 is fixed so that the center hole of the docking flange 1 is connected to the inside of the feed trough. Then, the cylinder 4 is fixed to the mounting shell 2 by the horizontal screw 3 and the nut 5, thus ensuring that the receiving box 6 enters the feed trough in parallel when picking up the material. That is, when picking up the material, the receiving box 6 is inserted into the feed trough and is not in the production line after being taken out, so as not to affect the production line. The baffle 8 can control the area of ​​the feeding area according to the actual amount of material entering the receiving box 6. In this way, if there are large lumps in the material, they can be intercepted by the baffle 8 and cannot enter the receiving box 6. Then the sampled material will move along the bottom surface of the receiving box 6 and flow out from the discharge port 7. Then the material enters the discharge funnel 9 and finally flows out from the discharge port of the discharge funnel 9 and is injected into the image particle size analyzer for detection through the pipeline. At this time, the particle picking and detection process can be completed.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
