Description

Technical Field

[0001] This utility model belongs to the technical field of material screening equipment, specifically relating to an externally mounted collection channel structure for a screen. Background Technology

[0002] In fields such as grain processing and chemical raw material screening, screening equipment is a key device for achieving material grading and impurity separation. In traditional screening equipment, impurity channels (large impurity channels and small impurity channels) and clean material channels are mostly located inside the screen body. This not only occupies the effective screening space of the screen body, resulting in a reduction in the effective screening area and a decrease in screening efficiency, but also makes it inconvenient to collect and detect impurities and materials in real time, causing inconvenience to quality control in the production process. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an external collection channel structure for the screen body, which arranges the impurity and clean grain channels on the outside of the screen body, without occupying the internal space of the screen body, increasing the effective screening area, and facilitating the collection and detection of impurities and materials.

[0004] The technical solution adopted by this utility model is as follows: an external collection channel structure for a sieve body, characterized in that it includes a stacked impurity channel and a clean grain channel disposed on the outside of the sieve body. The stacked impurity channel includes a small impurity channel and an extra-large impurity channel. The small impurity channel is used to collect small impurities from each layer after screening by the cleaning sieve, and the extra-large impurity channel is used to collect extra-large impurities after screening by the primary cleaning sieve. Both the small impurity channel and the extra-large impurity channel include multiple openings at the top and bottom. The clean grain channel is disposed at the clean grain discharge outlet on the side of the end of each sieve layer of the cleaning sieve, and is used to collect the clean grain from each path screened by the multi-layer sieve surface.

[0005] Furthermore, the small miscellaneous channel, the extra-large miscellaneous channel, and the clean grain channel are arranged vertically in parallel.

[0006] Furthermore, the small miscellaneous channel and the ultra-large miscellaneous channel are arranged side by side.

[0007] Furthermore, the grain cleaning channel is set up vertically and the lower end has an enlarged discharge outlet.

[0008] The beneficial effects of this utility model are:

[0009] 1. Increase the effective screening area: By placing all the impurity and clean grain channels on the outside, they no longer occupy the internal space of the screen body, thus significantly increasing the effective screening area of ​​the screen body and improving screening efficiency.

[0010] 2. Facilitates collection and testing: The external channel structure makes the collection of impurities more direct, and at the same time facilitates real-time testing of the collected impurities and clean grains, which is beneficial to quality control in the production process.

[0011] 3. High space utilization: The space layout between the screen body and the support legs is fully utilized, making the overall structure of the equipment more reasonable and significantly improving the space utilization rate. Attached Figure Description

[0016] To more clearly illustrate the technical solution of this utility model, the accompanying drawings used in the description will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings without creative effort. To facilitate understanding of this utility model, a more detailed description of this utility model will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, this utility model is an externally mounted collection channel structure outside the screen body, a key component of a symmetrical screening and impurity removal device. The structure includes a stacked impurity channel 100 and a clean grain channel 3, both located on the outside of the screen body. It includes a small impurity channel 1 for collecting small impurities, an extra-large impurity channel 2 for collecting large impurities, and a clean grain channel 3 for collecting clean grain. The small impurity channel 1 and clean grain channel 3 correspond to multiple outlets on the multiple layers of the cleaning screen 300. The extra-large impurity channel 2 corresponds to two openings at the end of the primary cleaning screen 200, facilitating the entry and exit of impurities. The small impurity channel 1 and extra-large impurity channel 2 are arranged vertically and parallelly, connected side-by-side, resulting in a compact channel structure that efficiently utilizes the space outside the screen body. The clean grain channel 3 is vertically positioned at the clean grain outlet on the side of each screen layer of the cleaning screen 300, with an enlarged outlet at the lower end, for collecting the clean grain separated from the multiple layers of the screen.

[0018] like Figure 3As shown, this utility model is installed on a multi-layer screen body with a primary cleaning screen 200 and a cleaning screen 300. During the screening process, small impurities after being screened by the cleaning screen 300 will enter the small impurity channel 1, while large impurities after being screened by the primary cleaning screen 200 will enter the extra-large impurity channel 2. The collection and subsequent transmission of impurities are completed by their respective upper and lower openings. The clean grain screened at the end of each screen layer of the cleaning screen 300 will enter the clean grain channel 3 through the openings on both sides of each layer, and finally enter the bottom clean grain collection plate from the lower screen side inlet to be collected and discharged.

[0019] Because the stacked impurity channel 100 and the clean grain channel 3 are externally located, they do not occupy the internal space of the screen body, thus significantly increasing the effective screening area of ​​the screen body and effectively improving screening efficiency. At the same time, the external channel structure makes the collection process of small and large impurities more direct, which facilitates real-time detection of collected impurities and is beneficial to quality control in the production process. In addition, this vertical, parallel and side-by-side layout also makes the overall structure more reasonable and greatly improves the space utilization rate.
