Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening technology, and in particular to a screening device for refractory castables. Background Technology
[0002] In the production and processing of refractory castables, screening devices are needed to remove large-volume impurities to ensure the purity of the refractory castable. Existing screening devices have significant shortcomings in practical applications. The core problem is that when materials pass through vibrating screens or filters, larger particles are trapped on the filter screen surface. As operation continues, these impurities gradually accumulate, leading to a decrease in screening efficiency. Cleaning is necessary, but traditional cleaning methods are extremely inconvenient. Operators often need to manually remove the bolts or clips securing the filter screen, remove the entire screen, and then empty it to remove the impurities. This process is not only time-consuming and labor-intensive but also increases the workload for workers. Therefore, there is an urgent need for a screening device that allows for rapid cleaning without disassembly, to improve the current operational difficulties. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a refractory castable screening device that can quickly remove impurities.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A refractory castable screening device includes a housing, a screening cylinder, a material box, and a power component.
[0005] The front wall of the box has a circular window, a cover door is provided at the circular window, a feeding port is provided on the cover door, and a discharge port is provided at the bottom of the box. The material bin is placed below the discharge port; The screening cylinder is horizontally located inside the box. Screening holes are arrayed at the bottom of the screening cylinder. One end of the screening cylinder is open and connected to a circular window. The other end of the screening cylinder is equipped with a sealing plate. The power unit is located on the rear wall of the box. The power unit passes through the box and is connected to the sealing plate, which is used to rotate the screening cylinder 180°.
[0006] Furthermore, the box is equipped with two horizontal support rods for supporting the screening cylinder. The two support rods are symmetrically located on both sides of the screening cylinder and are tangent to the screening cylinder.
[0007] Furthermore, two guide plates are fixedly installed inside the box, with the top of the guide plates fixedly connected to the corresponding support rods, and the bottom of the guide plates extending obliquely to the discharge port.
[0008] Furthermore, it also includes a scraper located inside the screening cylinder. The scraper is an arc-shaped plate and covers at least the upper half of the sealing plate. The scraper is tightly attached to the sealing plate by means of a snap or magnetic attraction. Two horizontal rods are fixed inside the screening cylinder, and the scraper slides on the two horizontal rods.
[0009] Furthermore, the scraper is equipped with a handle.
[0010] The advantages of this utility model are: it does not require disassembling the screening cylinder, can quickly clean the impurities inside the screening cylinder, and is very convenient to operate; the power component has two functions: first, it can swing the screening cylinder back and forth to speed up the screening rate; second, it can rotate the screening cylinder 180° to facilitate the removal of impurities inside the screening cylinder.

Figure 2 ; Figure 3 A diagram showing the internal structure of the screening cylinder is provided. Figure 4 A diagram showing the internal structure of the enclosure is provided.

[0012] like Figures 1-3 As shown, this embodiment provides a refractory castable screening device, including a housing 1, a screening cylinder 2, a material box 3, and a power component 4.
[0013] Specifically, such as Figure 1 , Figure 3 As shown, the front wall of the box 1 is provided with a circular window 11, the screening cylinder 2 is horizontally located inside the box 1, the bottom of the screening cylinder 2 is arrayed with screening holes 22, one end of the screening cylinder 2 is open and connected to the circular window 11, and the other end of the screening cylinder 2 is provided with a sealing plate 21.
[0014] Specifically, such as Figure 1 , Figure 2 As shown, a cover door 12 is provided at the circular window 11, and a feeding port 13 is provided on the cover door 12. The feeding port 13 is used to put the refractory castable to be screened into the screening cylinder 2.
[0015] Specifically, such as Figure 4 As shown, the bottom of the box 1 is provided with a discharge port 14, which is used to release the refractory castable after screening by the screening cylinder 2. The material box 3 is placed below the discharge port 14 to collect the refractory castable after screening.
[0016] Specifically, such as Figure 2 , Figure 3 As shown, the power component 4 is located on the rear wall of the housing 1. The power component 4 passes through the housing 1 and connects to the sealing plate 21. The power component 4 is used to rotate the screening cylinder 2 by 180°. There are many ways to implement the power component 4, such as motor drive, which will not be elaborated here.
[0017] Operating Instructions: With the cover door 12 closed, feed the refractory castable to be screened into the screening cylinder 2 through the feeding port 13; the power unit 4 swings the screening cylinder 2 back and forth within a certain range to accelerate the screening rate; the screened refractory castable is collected in the hopper 3; after screening, the power unit 4 rotates the screening cylinder 2 180°, at which point the screening hole 22 is located at the top of the screening cylinder 2; open the cover door 12, and the operator can use a scraping tool to remove impurities from the screening cylinder 2, which is very convenient; after the impurities are removed, close the cover door 12, and the power unit 4 rotates the screening cylinder 2 another 180° to prepare for the next screening task.
[0018] This embodiment does not require disassembling the screening cylinder 2, allowing for quick cleaning of impurities inside the screening cylinder 2, and the operation is very convenient. It is worth mentioning that before cleaning impurities, the screening cylinder 2 should be rotated 180° so that the screening holes 22 are located at the top of the screening cylinder 2. This is more conducive to cleaning impurities. Imagine if the screening cylinder 2 were not rotated 180°; impurities might fall through the screening holes 22 during the cleaning process.
[0019] Furthermore, to improve the stability of the screening cylinder 2 during the reciprocating oscillation process, the optimized solution in this embodiment is as follows: Figure 4 As shown, two horizontal support rods 15 are fixedly installed inside the housing 1. The support rods 15 are located below the horizontal plane containing the horizontal diameter of the screening cylinder 2, and are used to support the screening cylinder 2. The two support rods 15 are symmetrically located on both sides of the screening cylinder 2, and the support rods 15 are tangent to the screening cylinder 2. Regarding the connection method between the support rods 15 and the inner wall of the housing 1, a fixed connection or a rotating connection can be selected.
[0020] Furthermore, to facilitate the collection of the screened refractory castable into the hopper 3, the optimized solution in this embodiment is as follows: Figure 4 As shown, two symmetrical guide plates 16 are fixedly installed inside the box 1. When the support rod 15 is fixedly connected to the inner wall of the box 1, the top of the guide plate 16 is fixedly connected to the corresponding support rod 15, and the bottom of the guide plate 16 extends obliquely to the discharge port 14. When the support rod 15 is rotatably connected to the inner wall of the box 1, the top of the guide plate 16 is fixedly connected to the inner wall of the box 1, and the bottom of the guide plate 16 extends obliquely to the discharge port 14.
[0021] As mentioned above, after screening, workers need to use scraping tools to remove impurities from the screening cylinder 2. To further improve the efficiency of impurity removal, the optimized solution in this embodiment is as follows: Figure 5 As shown, the device also includes a scraper 5, which is located inside the screening cylinder 2. The scraper 5 is an arc-shaped plate and covers at least the upper half of the sealing plate 21. The scraper 5 is tightly attached to the sealing plate 21 by means of a snap or magnetic attraction. Two horizontal rods 23 are fixedly provided inside the screening cylinder 2. The scraper 5 is slidably engaged with the two horizontal rods 23. A handle 51 is provided on the scraper 5.
[0022] Instructions for use: After screening, the power unit 4 rotates the screening cylinder 2 180°, at which point the screening hole 22 is located at the top of the screening cylinder 2; open the cover door 12, and the operator holds the handle 51 and pulls the scraper 5 outward. As the scraper 5 moves along the horizontal bar 23, it will remove impurities, making the operation very convenient; after the impurities are removed, push the scraper 5 back to its original position. The scraper 5 will stick tightly to the sealing plate 21 by means of a buckle or magnetic attraction; close the cover door 12, and the power unit 4 rotates the screening cylinder 2 another 180° to prepare for the next screening task.
[0023] It should be noted that the scraper 5 is attached to the sealing plate 21 by means of a snap or magnetic attraction. The structure of the snap or magnetic attraction is not shown in the attached figure. Since these two structures are conventional, their structure and principle are not explained in detail. For example, the sealing plate 21 is made of metal and the scraper 5 is made of plastic. Several magnets are embedded in specific positions of the scraper 5. When the scraper 5 is close to the sealing plate 21, the two are attracted together. When the operator pulls the scraper 5 with external force, the scraper 5 can be separated from the sealing plate 21.
[0024] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
