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

[0023] Please see Figures 1-3 This utility model is a torpedo-shaped high-temperature resistant screen that is easy to prevent dust, including a dustproof outer sleeve 1, an inner high-temperature resistant screen cylinder 2, and a drive rotation assembly 3. The inner high-temperature resistant screen cylinder 2 has screen holes 24 evenly distributed along the wall at the middle position. The inner high-temperature resistant screen cylinder 2 has bearings 5 ​​sleeved on the outer wall near both ends, and the bearings 5 ​​are embedded in the dustproof outer sleeve 1. The dustproof outer sleeve 1 has a material leakage square tube 11 at the bottom near the bottom end. The dustproof outer sleeve 1 has an annular baffle 13 on the inner wall near the bottom end, and the inner high-temperature resistant screen cylinder 2 passes through the annular baffle 13. The drive rotation assembly 3 is installed on the upper part of the dustproof outer sleeve 1 near the top end and is used to drive the inner high-temperature resistant screen cylinder 2 to rotate. A support frame 4 is installed on the outer wall of the dustproof outer sleeve 1.

[0024] In the process of producing hot-pressed iron blocks using rotary kilns and hot presses, the reduced iron needs to undergo a screening process from the transfer silo to the feeding trolley to remove harmful elements such as dust that affect the quality of the hot-pressed iron blocks. After arriving at the transfer silo from the rotary kiln, the iron undergoes screening and then enters the feeding trolley. Here, it enters the inner high-temperature resistant screen cylinder 2. Driven by the rotating drive assembly 3, the inner high-temperature resistant screen cylinder 2 rotates, making the screening more thorough. The tumbling iron material leaks dust and other impurities through the screen holes 24, enters the dustproof outer sleeve 1, and slides down to the material leakage square tube 11 before falling down. The iron material tumbles and rolls downwards within the inner high-temperature resistant screen cylinder 2, entering the feeding trolley from the bottom, thus completing the screening process.

[0025] The torpedo-shaped design effectively solves the problem of insufficient internal space in the feed pipe, increasing the area of ​​the internal screen plate (traditionally flat and prone to clogging, the flipped design prevents clogging), and the two ends transition smoothly with the feed pipe to prevent material blockage during the feeding process. Because the inner high-temperature resistant screen cylinder 2 is fully enclosed, dust and environmental protection issues at the production site are effectively resolved. High-temperature and wear-resistant materials are selected for integral casting, meeting the process requirements for high temperature resistance, wear resistance, and dust prevention.

[0026] The gap between the outer wall of the inner high-temperature resistant screen cylinder 2 and the annular baffle 13 is very small (less than 1 mm), but it does not affect the rotation of the inner high-temperature resistant screen cylinder 2.

[0027] The inner high-temperature resistant screen cylinder 2 is provided with a trumpet-shaped inlet pipe 22 at the top and an elliptical outlet pipe 23 at the bottom.

[0028] The trumpet-shaped inlet pipe 22 facilitates material feeding, while the elliptical outlet pipe 23 is appropriately narrowed to facilitate precise material discharge.

[0029] The width between the inner walls of the two sides of the material leakage square tube 11 is not less than 1 / 3 of the width of the outer wall of the dustproof outer sleeve, and the length of the material leakage square tube 11 along the outer wall of the dustproof outer sleeve 1 is 30-50cm.

[0030] The circumference of the outer wall of the dustproof outer sleeve 1 is compared with the width of the 120° sector to the inner walls on both sides of the material discharge square tube 11, but the width of the inner walls on both sides of the material discharge square tube 11 is not greater than the inner diameter of the dustproof outer sleeve 1. The length of 30-50cm basically ensures material feeding.

[0031] The drive rotation assembly 3 includes a drive motor 31 and a drive gear disk 32. The dustproof outer sleeve 1 has a mounting block 12 fixed at the upper part near the top. The drive motor 31 is embedded in the mounting block 12. The drive gear disk 32 is sleeved on the shaft of the drive motor 31. The inner high-temperature resistant screen cylinder 2 has a gear belt 25 on the outer wall outside the top of the dustproof outer sleeve 1. The drive gear disk 32 meshes with the gear belt 25.

[0032] The drive motor 31 is a servo motor, which ensures that the inner high-temperature resistant screen cylinder 2 rotates and transports the screen for screening. The mounting block 12 is preferably heat-insulated to ensure that the temperature of the drive motor 31 does not get too high.

[0033] The support frame 4 includes a collar 41 and a support rod 42. The top end of the support rod 42 is rotatably connected to the bottom end of the collar 41 and can be locked at the installation angle with bolts and nuts. The collar 41 is fitted onto the outer wall of the dustproof outer sleeve 1.

[0034] The tilt angle of the dustproof outer sleeve 1 is adjusted by adjusting the angle between the collar 41 and the support rod 42. The support rod 42 is installed vertically.

[0035] The dustproof outer sleeve 1 is inclined downwards at 45-60° from top to bottom. This basically ensures inclined material feeding and also achieves a rolling screening effect.

[0036] The material leakage square tube 11 is connected to the negative pressure device. The negative pressure device is equivalent to a negative pressure tank connected to the material leakage square tube 11 through a pipe. The negative pressure can ensure that dust will not be emitted from both ends of the dustproof outer sleeve or that smoke or dust will enter at the bearing position, and can also dissipate heat to a certain extent inside.
