Currently, the device uses a telescopic cylinder and a guide plate to move the mounting frame without generating much noise. The main moving part, the screening part, and the auxiliary moving part work together to drive the screening part to finely screen the residue. However, this device requires multiple sets of cylinders to screen the residue, which greatly increases the cost of the device. It cannot achieve the energy-saving and environmentally friendly effect of slag screening, does not meet the needs of small workshops, and causes inconvenience to the staff.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a screening device for easy collection of coal-fired furnace slag particle size, comprising a box body, a feeding frame installed at the top of the box body, and a base installed at the bottom of the box body; a screening mechanism is provided inside the box body, and a collection component is provided inside one side of the bottom of the box body;

[0008] The screening mechanism includes a mounting frame, which is located inside the housing. A mesh frame is slidably connected to one side of the mounting frame. Sliding grooves are symmetrically opened on the inner side of the housing, and fixed rods are installed inside the sliding grooves. Sliding sleeves are symmetrically installed at both ends of the mounting frame, and the sliding sleeves are slidably connected to the outside of the fixed rods. First telescopic springs are symmetrically sleeved on the outside of the fixed rods. Rotating rods are symmetrically rotatably connected inside the housing. A motor is installed at one end of the rotating rod, and a rotating wheel is installed on the outside of one end of the rotating rod. A belt is sleeved between the outside of the rotating wheels. Discs are installed on the outside of both ends of the rotating rod, and protrusions are installed on the outside of the discs.

[0009] Preferably, the box body has symmetrical slots on one side, and a limit box is symmetrically installed on one side of the wire frame. The limit box is slidably connected to a moving rod, and a connecting plate is installed at one end of the moving rod. A baffle is installed on the outer side of one end of the moving rod, and a second telescopic spring is sleeved on the outer side of the moving rod. A plug is installed on one side of the connecting plate, and the plug is inserted into the mounting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This is a screening device for easily collecting coal slag particles, the specific contents of which are as follows: The operator starts the motor to drive the rotating rods to rotate. Through the cooperation between the rotating wheel and the belt, two sets of rotating rods rotate inside the housing. The rotation of the rotating rods drives the rotation of multiple sets of discs, which in turn drives the rotation of multiple sets of protruding blocks. The rotation of the discs causes the protruding blocks to rotate intermittently, thus causing the protruding blocks to intermittently strike the bottom of the mounting frame. At this time, the mounting frame drives the sliding sleeve to slide outside the fixed rod. Simultaneously, the first telescopic spring contracts or extends, thereby achieving the effect of the two sets of screen frames shaking up and down for screening. This technology enables multi-stage fine screening of slag, allowing for uniform screening of slag of various specifications. Compared to existing technologies that use multiple sets of cylinders for driving, it has a lower operating cost and meets the needs of small workshops. By having the operator pull the U-shaped rod and slide it inside the positioning box, the sliding plate slides inside the positioning box. At this time, the third telescopic spring retracts, and through the reset property of the third telescopic spring, multiple sets of positioning blocks and insert plates are connected, thereby achieving the effect of quickly fixing and limiting the collection box. This facilitates the quick replacement and cleaning of the collection box by the operator, greatly improving the efficiency of slag recycling and cleaning after screening.

[0016] 1. The motor is started by the operator, driving the rotating rods to rotate. The rotation of the rotating rods drives the rotating wheel to rotate. Through the interaction between the rotating wheel and the belt, two sets of rotating rods rotate inside the housing. The rotation of the rotating rods drives multiple sets of discs to rotate, which in turn drives multiple sets of protruding blocks to rotate. The intermittent rotation of the protruding blocks causes them to intermittently strike the bottom of the mounting frame. At this time, the mounting frame causes the sliding sleeve to slide outside the fixed rod. Simultaneously, the first telescopic spring contracts or extends, achieving the effect of up-and-down shaking and screening of the two sets of screen frames. This enables multi-stage fine screening of slag, allowing for the processing of slag of various specifications. This method achieves uniform screening and is more cost-effective than existing technologies that use multiple sets of cylinders for driving. It meets the needs of small workshops. The operator inserts the screen frame into one side of the installation frame and then pulls the moving rod to slide inside the limit box. The movement of the moving rod causes the connecting plate to move, and the second telescopic spring retracts. By releasing the moving rod, the second telescopic spring quickly extends and resets, allowing multiple sets of inserts to connect with the installation frame. This enables quick installation and disassembly of the screen frame, facilitating the rapid collection of screened slag and the cleaning and maintenance of the screen frame.

[0017] 2. The worker inserts the collection box into the bottom side of the housing. At this time, the slag enters the collection box after being screened by two sets of mesh frames. The insert plate is then inserted into the fixing plate. The worker then pulls the U-shaped rod to slide inside the positioning box. The sliding plate slides inside the positioning box, and the third telescopic spring retracts. By releasing the U-shaped rod and the restoring property of the third telescopic spring, multiple sets of positioning blocks are inserted into the insert plate, thereby achieving the effect of quickly fixing and limiting the collection box. This facilitates the worker's quick replacement and cleaning of the collection box, greatly improving the efficiency of slag recycling and cleaning after screening, and bringing convenience to the worker during use.

[0032] Working principle: Before using this screening device for easily collecting coal-fired furnace slag particles, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 8As shown, firstly, the worker pours the slag into the box 1 through the feed frame 101. At this time, two sets of mesh frames 202 classify and filter the slag. The worker starts the motor 208, which drives the rotating rod 207 to rotate. The rotation of the rotating rod 207 drives the rotating wheel 209 to rotate. Through the cooperation between the rotating wheel 209 and the belt 210, the two sets of rotating rods 207 rotate inside the box 1. The rotation of the rotating rod 207 drives the rotation of multiple sets of discs 211. The rotation of the discs 211 drives the rotation of multiple sets of protrusions 212. The protruding block 212 is a rubber block in the prior art. The rotation of the disc 211 drives the protruding block 212 to rotate intermittently, causing it to intermittently strike the bottom of the mounting frame 201. At this time, the mounting frame 201 drives the sliding sleeve 205 to slide outside the fixed rod 204. Simultaneously, the first telescopic spring 206 contracts or extends, thus achieving the effect of up-and-down shaking and screening of the two sets of mesh frames 202. This enables multi-stage fine screening of slag, allowing for the uniform screening of slag of various specifications, compared to existing technologies. The technology employs a multi-cylinder drive method, resulting in lower operating costs and meeting the needs of small workshops. The rubber-material protrusions 212 cushion the impact on the mounting frame 201, reducing noise. When the worker inserts the mesh frame 202 into one side of the mounting frame 201, they pull the moving rod 215, which slides within the limit box 214. This movement of the moving rod 215 causes the connecting plate 216 to move, causing the second telescopic spring 218 to contract. Releasing the moving rod 215 causes the second telescopic spring 218 to quickly extend and reset, allowing the multiple insertion blocks 219 to connect with the mounting frame 201. This enables rapid installation and removal of the mesh frame 202, facilitating the quick collection of screened slag and the cleaning and maintenance of the mesh frame 202. This significantly improves the efficiency of daily maintenance and provides convenience for users. The detachable connection between the sealing plate 220 and the slot 213 allows for sealing of the housing 1.

[0033] The worker inserts the collection box 301 into the bottom side of the box 1. At this time, the slag enters the collection box 301 after being screened by two sets of mesh frames 202. The insert plate 303 is then inserted into the fixing plate 302. The worker then pulls the U-shaped rod 305 to slide inside the positioning box 304. At this time, the sliding plate 307 slides inside the positioning box 304. The third telescopic spring 306 retracts. By releasing the U-shaped rod 305 and then restoring the third telescopic spring 306, multiple sets of positioning blocks 308 are inserted into the insert plate 303. This achieves the effect of quickly fixing and limiting the collection box 301, which facilitates the worker's quick replacement and cleaning of the collection box 301. This greatly improves the efficiency of the worker's slag recycling and cleaning after screening and brings convenience to the worker during use.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
