Description

Technical Field

[0001] The utility model relates to the technical field of raw material cleaning, in particular to a raw material cleaning device. Background Art

[0002] Raw materials are the products used as the starting point of the production process. Raw materials are divided into two categories: natural forest products, minerals, and marine products, such as iron ore and crude oil; and agricultural products. In feed raw materials, impurities from animal protein feeds (such as fishmeal and meat and bone meal), mineral feeds (such as stone powder and shell powder), and additives such as trace elements and pharmaceuticals are cleaned during raw material production and generally do not require cleaning at the feed factory. Feed raw materials that require cleaning primarily include grain feeds and their processing by-products, primarily to remove foreign matter, metal, and other debris.

[0003] In the prior art, common raw material cleaning equipment is equipped with a magnetic separation device to screen out iron filings from the raw materials. However, these devices typically attract iron filings with permanent magnets, requiring regular cleaning of the magnetic separation device, which increases subsequent maintenance costs. Inventing a raw material cleaning device to address these issues has become a pressing issue for those skilled in the art. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a raw material cleaning device, which aims to improve the problem that common raw material cleaning equipment needs to regularly clean the iron filings on the magnetic separation device.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a raw material cleaning device, comprising a collecting trough and a vibrating screen and a fixed sleeve arranged on the collecting trough, wherein the upper end of the collecting trough is fixedly connected to four brackets, the upper ends of the brackets are fixedly connected to a feeding frame, the inner wall of the feeding frame is fixedly connected to a plurality of fixing blocks, the fixing blocks are fixedly connected to support springs, and the lower end of the collecting trough is installed with an electromagnetic cylinder;

[0007] The outer wall of the vibrating screen is fixedly connected to a mounting block fixedly connected to the upper side wall of the support spring, and the outer walls on both sides of the vibrating screen are installed with vibration motors;

[0008] The bottom end of the fixed sleeve is installed at the bottom of the collecting tank, and a motor installed on the collecting tank is provided inside the fixed sleeve. A main shaft is installed on the inner wall of the fixed sleeve, and a lower limit ring and an upper limit ring are fixedly connected to the outer wall of the bottom end of the main shaft respectively. A plurality of stirring blades are fixedly connected to the outer wall of the main shaft near the upper limit ring, and an adjusting groove is opened on the outer wall of one side of the stirring blade, and a scraper is installed on the inner wall of the adjusting groove.

[0009] Preferably, the output end of the motor is fixedly connected to one end of the main shaft, the outer wall of the main shaft is rotatably connected to the inner wall of the fixed sleeve, and the electromagnetic cylinder generates magnetism when energized.

[0010] Preferably, the outer sides of the lower limiting ring and the upper limiting ring are umbrella-shaped.

[0011] By adopting the above technical solution, the raw materials are placed on the vibrating screen, and then the vibration motor is started to vibrate the entire screen under the action of the supporting spring to screen out foreign matter in the raw materials. When the raw materials pass through the electromagnetic cylinder below, the inner wall of the electromagnetic cylinder adsorbs and cleans impurities such as iron filings in the raw materials, and the cleaned raw materials fall into the collection trough below for collection.

[0012] Preferably, an electromagnet is fixedly connected to the outer wall of the main shaft between the lower limit ring and the upper limit ring, and the electromagnet is connected to the input end of the electromagnetic cylinder.

[0013] Preferably, a plurality of return springs are fixedly connected to the inner wall of the adjustment groove, a side wall of one end of the return spring is fixedly connected to one end of the scraper, and an outer wall of the scraper is slidably connected to the inner wall of the adjustment groove.

[0015] Preferably, one end of the sliding rod is magnetically connected to the outer wall of the electromagnet.

[0016] By adopting the above technical solution, while the electromagnetic cylinder cleans the iron filings in the raw material, the main shaft drives the outer stirring blade to rotate, thereby increasing the residence time of the raw material inside the cylinder and thus improving the iron filings screening effect.

[0017] The beneficial effects of the utility model are:

[0018] The vibrating screen can vibrate the raw materials continuously to disperse them, avoid accumulation of raw materials and thus improve screening efficiency. At the same time, the electromagnetic cylinder can adsorb and screen out iron filings in the raw materials when powered on, and the stirring blades inside the electromagnetic cylinder increase the residence time of the raw materials in the electromagnetic cylinder while rotating, thereby further improving the screening effect of iron filings. At the same time, the scraper scrapes the inner wall of the electromagnetic cylinder when the electromagnetic cylinder and the electromagnet are powered off, and scrapes off the iron filings that have not fallen off the inner wall of the electromagnetic cylinder in time due to residual magnetism, thereby improving the cleaning effect of the electromagnetic cylinder, avoiding the adsorbed iron filings affecting the subsequent use effect, and reducing the cost of subsequent maintenance.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example, see Figure 1-Figure 4 A raw material cleaning device includes a collecting tank 1 and a vibrating screen 7 and a fixing sleeve 9 arranged on the collecting tank 1. Four brackets 2 are fixedly connected to the upper end of the collecting tank 1. The upper end of the bracket 2 is fixedly connected to a feeding frame 3. The inner wall of the feeding frame 3 is fixedly connected to a plurality of fixing blocks 4. The fixing blocks 4 are fixedly connected to support springs 5. An electromagnetic cylinder 6 is installed at the lower end of the collecting tank 1.

[0027] The outer wall of the vibrating screen 7 is fixedly connected to a mounting block 8 which is fixedly connected to the upper side wall of the support spring 5. Vibrating motors 21 are installed on both sides of the outer wall of the vibrating screen 7.

[0028] The bottom end of the fixed sleeve 9 is installed at the bottom of the collecting tank 1. The interior of the fixed sleeve 9 is provided with a motor 10 installed on the collecting tank 1. The inner wall of the fixed sleeve 9 is provided with a main shaft 11. The outer wall of the bottom end of the main shaft 11 is fixedly connected with a lower limit ring 12 and an upper limit ring 13 respectively. The outer wall of the main shaft 11 near the upper limit ring 13 is fixedly connected with multiple stirring blades 14. An adjusting groove 15 is provided on the outer wall of one side of the stirring blade 14, and a scraper 18 is installed on the inner wall of the adjusting groove 15.

[0029] further; the output end of the motor 10 is fixedly connected to one end of the main shaft 11, the outer wall of the main shaft 11 and the inner wall of the fixed sleeve 9 are rotatably connected, the electromagnetic cylinder 6 generates magnetism when energized, and the outer side of the lower limit ring 12 and the upper limit ring 13 is umbrella-shaped.

[0030] It should be noted that: the raw materials are placed on the vibrating screen 7, and then the vibration motor 21 is started. The electromagnetic cylinder 6 makes the screen vibrate as a whole under the action of the support spring 5, so that the raw materials are constantly moving, and foreign matter in the raw materials can be quickly screened out. When the screened raw materials pass through the electromagnetic cylinder 6 below, the inner wall of the electromagnetic cylinder 6 adsorbs and cleans impurities such as iron filings in the raw materials. The cleaned raw materials fall into the collection tank 1 below for collection, which is convenient for subsequent removal.

[0031] Furthermore; an electromagnet 20 is fixedly connected to the outer wall of the main shaft 11 near the lower limit ring 12 and the upper limit ring 13, the electromagnet 20 is connected to the input end of the electromagnetic cylinder 6, and a plurality of return springs 17 are fixedly connected to the inner wall of the adjusting groove 15, and one end side wall of the return spring 17 is fixedly connected to one end of the scraper 18, and the outer wall of the scraper 18 is slidingly connected to the inner wall of the adjusting groove 15. A slide groove 16 is provided on one side of the adjusting groove 15, and one end of the scraper 18 is fixedly connected to a slide rod 19 that is slidingly connected to the inner wall of the slide groove 16, and one end of the slide rod 19 is magnetically connected to the outer wall of the electromagnet 20.

[0032] It should be noted that: while the electromagnetic cylinder 6 is cleaning the iron filings in the raw material, the motor 10 drives the stirring blade 11 on the outside of the main shaft 14 to rotate. When the stirring blade 14 rotates, it continuously stirs the raw material passing through the inside of the electromagnetic cylinder 6, so that the raw material is continuously stirred and contacts the inner wall of the electromagnetic cylinder 6, thereby increasing the residence time in the electromagnetic cylinder 6, thereby further improving the screening effect of iron filings. After that, the raw material in the collecting tank 1 is removed. After the raw material collection is completed, the electromagnetic cylinder 6 and the electromagnet 20 are closed. At this time, the magnetism of the electromagnetic cylinder 6 and the electromagnet 20 slowly lose their magnetism, and at the same time, under the rebound of the return spring 17, the scraper 18 extends out of the adjusting groove 15 and contacts the inner wall of the electromagnetic cylinder 6. At the same time, the iron filings on the outer wall of the electromagnetic cylinder 6 fall into the collecting tank 1 below under the action of gravity, and during the rotation of the main shaft 11, the scraper 18 rotates continuously to scrape off the smaller iron filings adsorbed on the inner wall of the electromagnetic cylinder 6, so as to avoid the influence of untimely cleaning of iron filings on the subsequent screening effect.

[0033] The working principle of this raw material cleaning equipment:

[0034] Put the raw materials on the vibrating screen 7, then start the vibration motor 21 and the electromagnetic cylinder 6 to vibrate the screen as a whole under the action of the support spring 5, so that the raw materials are constantly moving, and foreign matter in the raw materials can be quickly screened out. When the screened raw materials pass through the electromagnetic cylinder 6 below, while the electromagnetic cylinder 6 cleans the iron filings in the raw materials, the motor 10 drives the stirring blade 11 on the outside of the main shaft 14 to rotate. When the stirring blade 14 rotates, it continuously stirs the raw materials passing through the inside of the electromagnetic cylinder 6, so that the raw materials are continuously stirred and contacted with the inner wall of the electromagnetic cylinder 6, thereby increasing the residence time in the electromagnetic cylinder 6, thereby further improving the screening effect of iron filings, and then the collection The raw materials in the collecting tank 1 are removed, and the electromagnetic cylinder 6 and the electromagnet 20 are closed after the raw materials are collected. At this time, the magnetism of the electromagnetic cylinder 6 and the electromagnet 20 slowly loses, and at the same time, the scraper 18 extends out of the adjusting slot 15 and contacts the inner wall of the electromagnetic cylinder 6 under the rebound of the return spring 17. At the same time, the iron filings on the outer wall of the electromagnetic cylinder 6 fall into the collecting tank 1 below under the action of gravity, and during the rotation of the main shaft 11, the scraper 18 rotates continuously to scrape off the smaller iron filings adsorbed on the inner wall of the electromagnetic cylinder 6, so as to avoid the influence of untimely cleaning of iron filings on the subsequent screening effect, thereby timely cleaning the iron filings adsorbed on the electromagnetic cylinder 6, avoiding the influence of iron filings on the subsequent use effect while reducing the cost of subsequent maintenance.

[0035] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
