Description

Technical Field

[0001] The utility model relates to the field of particle material purification equipment and discloses a particle cleaner with a polluted gas discharge port added at the final stage. Background Art

[0002] At present, particle cleaners are often used in packaging operations in the petrochemical and chemical industries to purify pellets produced by extruders, die heads and other machines and then sent to the packaging system by wind. Although there are many types of particle cleaners on the market that use different principles to purify pellets, the method of using airflow as a carrier to separate and transport impurities outside the equipment has always existed in particle cleaners of various principles. In the commonly used particle cleaner equipment on the market, the contaminated gas flow that transports impurities often re-mixes with the pellet flow, resulting in the particle cleaner's effect of purifying pellets being unsatisfactory or even greatly reduced.

[0003] This patent proposes a feasible technical solution to solve the problem of repeated mixing of polluted gas flow and granular flow. By adding relevant methods and facilities, the polluted gas flow and the granular flow are reasonably avoided to reduce the mutual contact between the two, thereby improving the effect of the particle cleaner in purifying the granular material and providing a guarantee for the purification effect of the particle cleaner. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned particle cleaner equipment, the utility model provides a solution for a particle cleaner with an additional polluted gas discharge port at the final stage, thereby improving the secondary mixing phenomenon of the polluted gas flow and the particle flow inside the existing particle cleaner, and further improving the equipment performance of the particle cleaner commonly used in the market.

[0005] The utility model provides a particle cleaner with a polluted gas discharge port added at the last stage, which is used to increase the material cleaning effect. The utility model comprises basic structures such as a particle inlet, a particle outlet, a particle cleaner shell, a guide plate, a particle cleaner cavity partition plate, a polluted gas discharge port and a clean air inlet of the particle cleaner. On the basis of the basic structure, a polluted gas discharge port is added at the last stage of the particle cleaner.

[0006] Furthermore, the polluted gas discharge port added at the last stage of the particle cleaner may be a single-stage or multi-stage polluted gas discharge port, and each stage of the polluted gas discharge port may be configured as one or more discharge port structures.

[0007] Furthermore, the polluted gas discharge port added at the last stage of the particle cleaner has an appearance of a plurality of arranged holes or a plurality of gaps between baffles.

[0008] Furthermore, the polluted gas discharge port added at the last stage of the particle cleaner can adjust the flow rate according to production needs to facilitate adjustment and control. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation plan

[0018] The following is a detailed description of a schematic diagram of an application case device in combination with the solution of the utility model. In each of the figures in the case, the solid arrows represent the flow direction 11 of the clean air, the hollow arrows represent the flow direction 12 of the polluted gas, the scattered dots represent the granules, and the single-line arrows represent the movement direction 13 of the granules. Figure 2 As shown, the interior of the particle cleaner housing 6 is divided into two parts by the particle cleaner cavity partition plate 8, and the front part is the main cavity 9 of the particle cleaner. Figure 3 It can be seen that the particle cleaner cavity partition plate 8 is a solid plate connected to the clean air inlet 5; the particle cleaner polluted gas discharge port 2 and the additional polluted gas discharge port 21 are connected to the particle cleaner cavity partition plate 8; the particle cleaner polluted gas centralized discharge port 7 is connected to the particle cleaner housing 6. The particle cleaner polluted gas discharge port 2 and the additional polluted gas discharge port 21 collect the polluted gas and gather it to the particle cleaner polluted gas centralized discharge port 7 to uniformly discharge it from the particle cleaner.

[0019] In the actual production process, the pellets in the silo enter the equipment through the pellet cleaner pellet inlet 1, are guided by the main guide plate 4 inside the pellet cleaner, and move downward along the preset channel of the guide plate of the pellet cleaner in the direction of the single-line arrow 13. The running track of the pellets in the pellet cleaner is as shown in FIG. Figure 6 As shown, the clean particles roll down through the main guide plate 4 inside the particle cleaner to the auxiliary guide plate 41, and finally flow out from the particle outlet 3 of the particle cleaner.

[0020] The final position of the particle cleaner described in the utility model is the lower half of the main particle cleaner. Under actual working conditions, polluted gas will still be generated at the end position. Therefore, in this embodiment, polluted gas discharge ports 21 are additionally provided at the lower positions of the inner ends of the main flow plate 4 inside the particle cleaner. In specific applications, any polluted gas discharge port provided in the lower half of the space inside the particle cleaner is a technical solution that can be thought of by those skilled in the art through the utility model.

[0021] In the final area of ​​the clean treatment of the particle cleaner material flow, although the impurity content of the material has been greatly reduced, impurities can still be produced. It is extremely important for a high-precision particle cleaner to avoid repeated contact between this part of the polluted air flow mixed with impurities and the particle flow. If the polluted air in this area is allowed to contact chaotically with the particle material, it is impossible to achieve high-precision particle cleaning. In this case, a polluted gas discharge port 21 is added at the end of the particle cleaner equipment in order to improve the purification efficiency of the particle material. Figure 1 As shown, from the front cross-sectional view of the particle cleaner, it can be seen that the solid arrows indicate that the clean air enters the main cavity 9 of the particle cleaner from the clean air inlet 5 to purify the granular material; the hollow arrows indicate that the airflow carrying impurities, that is, the polluted gas described in the present invention, flows to the polluted gas discharge ports 2 and 21 of the particle cleaner, passes through the particle cleaner cavity partition plate 8, and is gathered to the particle cleaner polluted gas centralized discharge port 7 for discharge. It is precisely because the polluted gas discharge port 21 is added at the last stage of the particle cleaner, thereby reducing or avoiding the polluted gas generated by the granular material on the secondary guide plate 41 from overlapping with the running track of the granular material flowing on the main guide plate 4 inside the particle cleaner and entering the polluted gas discharge port 2, and the polluted gas generated by the granular material on the secondary guide plate 41 can be discharged through the additional polluted gas discharge port 21, thereby improving the purification effect of the particle cleaner.

[0022] In this case, a polluted gas discharge port 21 is added in the area of ​​the final stage of the particle cleaner to improve the cleaning effect. The polluted gas discharge port added in the final stage can be divided into multiple sections or multiple stages, such as Figure 7 A secondary polluted gas discharge port 24 is added. The segments or stages can be in the form of multi-stage arranged holes or gaps between multi-stage baffles, such as Figure 4 The polluted gas discharge port hole pattern 22 and Figure 5The polluted gas discharge port baffle gap pattern 23 is shown, and each pattern of the polluted gas discharge port can be designed into multiple sections or multiple stages, such as Figure 7 The figure shows a schematic diagram of a multi-stage arrangement of polluted gas discharge ports. At the same time, according to the specific implementation requirements of the working conditions, the air flow rate of the polluted gas discharge port added at the last stage of the particle cleaner can be adjusted and controlled to control the air flow rate and air flow speed. For example, manual or electric valves, or controllers can be selected to better utilize the polluted gas discharge port to meet the high cleanliness effect of the particle cleaner to clean the granular materials.

[0023] This polluted air discharge port is simple to manufacture and does not require the addition of additional equipment. It can be simply added to the original internal structure of the particle cleaner. It is low-cost and high-effective, and is a good means to improve the working performance of the particle cleaner.

[0024] The beneficial effects of the present invention are as follows: the additional polluted gas discharge port improves the purification effect of the particle cleaner, the equipment is simple to manufacture, no new internal components or equipment are required, the design form is flexible and diverse, and the best use effect is achieved at the lowest cost.
