Description

Technical Field

[0002] Sintered brick refers to bricks made of clay, shale, coal gangue or fly ash, which are made through molding and high-temperature roasting and are used for building load-bearing and non-load-bearing walls. Depending on the raw materials, sintered bricks can be divided into sintered clay bricks, sintered fly ash bricks, sintered shale bricks, etc. In the production process of sintered bricks, one of the steps is to screen the granular raw materials used to make sintered bricks, so as to screen out a small part of the larger volume of raw materials in the granular raw materials. At this time, a screening device is needed.

[0003] The existing Chinese patent with announcement number CN219253253U discloses an anti-blocking sintered brick raw material screening device, including a screening box shell, and a feed pipe is connected to the side of the screening box shell, and a discharge hole is opened on the side of the screening box shell. The anti-blocking sintered brick raw material screening device also includes: two first square holes, which are respectively opened on both sides of the screening box shell.

[0004] Although the above scheme can automatically and fully clean the blockages inside the sieve holes of the screening mesh plate, the collision between the raw materials when the device screens the raw materials will cause dust to be raised, which is easy to cause harm to human health. At the same time, after the device screens out unqualified raw materials, it is relatively troublesome to remove them, affecting their use. Therefore, it does not meet the existing needs. In this regard, we propose a raw material screening device for sintered bricks. Utility Model Content

When screening is performed, the screening net can be vibrated up and down by the elastic action of the reset spring, thereby improving the screening effect. When the screening is completed, the user can open the first sealing door, and start the first motor to enable the L-shaped plate to drive the screening net to rotate. The user can move the collecting tool such as a tray to the inside of the screening chamber. When the screening net rotates, unqualified raw materials on its upper end will fall into the tray below, so that the unqualified raw materials can be conveniently collected. At the same time, the user can also clean the screening net, which is easy to use.

Three equidistantly distributed dustproof nets 15 are arranged inside the collecting chamber 13.

[0028] When in use, the user opens the first sealing door 18 and moves the tray to the lower side of the screening chamber 2, and starts the first motor 5 to make the rotating shaft 6 drive the L-shaped plate 3 to rotate synchronously. The rotation of the L-shaped plate 3 will drive the screening net 4 to rotate synchronously so that the unqualified raw materials on the upper end of the screening net 4 fall into the tray below, thereby realizing the discharge of unqualified raw materials. At the same time, the user can clean the screening net 4.

[0029] See also Figure 2 and Figure 3 , the upper sides of both sides of the screening chamber 2 are provided with first motors 5, and the output end of the first motor 5 is connected to the rotating shaft 6 through a coupling transmission, and the first motor 5 can provide power for the rotation of the screening net 4;

[0030] See also Figure 4 The lower side of the outer portion of the guide rod 7 is sleeved with a return spring 8, one end of the return spring 8 is connected to the screening net 4, and the other end of the return spring 8 is connected to the L-shaped plate 3. The return spring 8 can make the screening net 4 vibrate up and down to improve the screening effect;

[0031] See also Figure 2 An air suction machine 14 is provided below the collecting chamber 13. The collecting chamber 13 is connected to the air suction machine 14 and the annular groove 10 through a connecting pipe 12. The air suction machine 14 can make the annular groove 10 generate suction to suck in dust to prevent the dust from escaping.

[0032] See also Figure 2 A screw conveying rod 17 is rotatably provided at the lower side of the screening chamber 2, a second motor 16 is provided at the lower side of one side of the screening chamber 2, and the second motor 16 is connected to the screw conveying rod 17 through a coupling. After the screw conveying rod 17 rotates, qualified raw materials can be screw-conveyed, which can avoid blockage during discharging;

[0033] See also Figure 1 and Figure 3 Two first sealing doors 18 are movably installed at the middle position of the front end of the main body 1, and a second sealing door 19 is movably installed on one side of one of the first sealing doors 18. The first sealing door 18 can be used to conveniently clean the dust inside the collection chamber 13, and the second sealing door 19 can be used to clean unqualified raw materials;

[0034] See also Figure 3 and Figure 4 , an anti-slip plate 9 is arranged above the L-shaped plate 3, and the anti-slip plate 9 is adhered and fixed to the guide rod 7. The setting of the anti-slip plate 9 can prevent the screening net 4 from falling out.

[0035] Working principle: when in use, the raw materials of sintered bricks are added into the screening chamber 2 from the upper end of the main body 1, and the raw materials will fall onto the screening net 4 due to gravity. The screening net 4 will squeeze the reset spring 8 when being collected, and the reset spring 8 will recover after being compressed, so that the energy released by it can make the screening net 4 move up, realize the up and down vibration of the screening net 4, and improve the screening effect.

When screening, the user can start the suction machine 14, and the suction machine 14 can generate negative pressure in the annular groove 10 through the connecting pipe 12, and then generate suction through the through hole 11. When dust escapes from the upper end of the screening chamber 2, it can be sucked into the collection chamber 13, and then it can be fully intercepted by the three dust-proof nets 15 to prevent dust from entering the interior of the suction machine 14, so that the dust stays at the upper end of the dust-proof net 15, which can prevent the escape of dust and avoid pollution of the working environment. The user's health is affected. The user only needs to open the second sealing door 19 to clean the dust inside, ensuring a long-term dust-proof effect. After the qualified raw materials are screened out, the raw materials will fall into the lower end of the screening chamber 2 by gravity. At this time, the second motor 16 is started, and the screw conveying rod 17 can be rotated through the coupling. The rotation of the screw conveying rod 17 can spirally convey the qualified raw materials, thereby avoiding blockage when the qualified raw materials are discharged. After the user opens the first sealing door 18, the tray is moved to the lower side of the screening chamber 2, and the first motor 5 is started. The rotating shaft 6 can be rotated under the transmission of the coupling, thereby driving the L-shaped plate 3 to rotate synchronously. The L-shaped plate 3 will drive the screening net 4 to rotate synchronously, so that the unqualified raw materials on the upper end of the screening net 4 fall into the tray below, realizing the discharge of unqualified raw materials. At the same time, the user can clean the screening net 4, which is practical.
