[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for preparing sintered coal gangue hollow bricks, comprising a support frame for supporting the preparation of sintered coal gangue hollow bricks, a lower support plate connected to the top of the support frame, a side baffle installed on the side of the lower support plate, a second telescopic rod installed on the side of the side baffle, a connecting plate connected to the movable part of the second telescopic rod, a second hollow column installed on the side of the connecting plate away from the second telescopic rod, a second spring disposed inside the second hollow column, a scraper connected to the end of the second spring away from the connecting plate, an arc-shaped plate installed on the outer periphery of the scraper, a recycling box slidably connected to the bottom of the scraper, and a connecting frame connected to the side of the recycling box.

[0006] Preferably, a fixing rod is installed on the top of the support frame, an upper support plate is provided on the outer periphery of the fixing rod, a compression cylinder is installed on the top of the upper support plate, a first telescopic rod is connected to the output end of the compression cylinder, an extrusion plate for extruding sintered coal gangue hollow brick raw materials is installed on the end of the first telescopic rod away from the compression cylinder, a residual material collection box is provided on the top of the extrusion plate, a second motor is provided inside the extrusion plate, and a gear disk is connected to the output shaft of the second motor.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] The device for preparing hollow bricks from sintered coal gangue benefits from the scraper structure. The second telescopic rod extends, and the connecting plate drives the scraper to move towards the circular hollow brick preparation rod. Due to the action of the second spring, the scraper makes full contact with the circular hollow brick preparation rod, causing the rod to rotate. Residual material on the surface of the rod is scraped off and falls into a recycling box, which can be removed for cleaning. This structure effectively cleans residual material from the circular hollow brick preparation rod, preventing it from affecting the shape and dimensional accuracy of the brick blank and reducing quality problems such as cracks or reduced strength.

[0014] The device for preparing sintered coal gangue hollow bricks benefits from the structure of the V-shaped rotating frame and scraper. The output shaft of the first motor drives the rotating column to rotate, which in turn drives the V-shaped rotating frame and scraper to rotate. The V-shaped rotating frame and scraper cut the raw material, and some of the excess raw material is squeezed into the waste material collection box through the hollow brick circular preparation insert. This structure can open holes in the brick blank, making the opening process smoother. Attached Figure Description

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 5 The apparatus shown is for preparing sintered coal gangue hollow bricks. It includes a support frame 1 for supporting the preparation of sintered coal gangue hollow bricks. A lower support plate 104 is connected to the top of the support frame 1. A side baffle 4 is installed on the side of the lower support plate 104. A second telescopic rod 401 is installed on the side of the side baffle 4. A connecting plate 402 is connected to the movable part of the second telescopic rod 401. A second hollow column 403 is installed on the side of the connecting plate 402 away from the second telescopic rod 401. A second spring 408 is disposed inside the second hollow column 403. A scraper 405 is connected to the end of the second spring 408 away from the connecting plate 402. An arc-shaped plate 404 is installed on the outer periphery of the scraper 405. A recycling box 406 is slidably connected to the bottom of the device, and a connecting frame 407 is connected to the side of the recycling box 406. After the hollow brick circular preparation rod 204 is raised, the second telescopic rod 401 extends, and the connecting plate 402 drives the scraper 405 to move toward the hollow brick circular preparation rod 204. Due to the action of the second spring 408, the scraper 405 is in full contact with the hollow brick circular preparation rod 204. The second motor 6 is turned on, and the output shaft of the second motor 6 drives the gear disk 601 to rotate. The gear disk 601 drives the hollow brick circular preparation rod 204 to rotate, and the residual material on the surface of the hollow brick circular preparation rod 204 is scraped off and falls into the recycling box 406. The recycling box 406 can be removed for cleaning.

[0026] A fixing rod 206 is installed on the top of the support frame 1. An upper support plate 2 is provided on the outer periphery of the fixing rod 206. A compression cylinder 201 is installed on the top of the upper support plate 2. The output end of the compression cylinder 201 is connected to a first telescopic rod 202. An extrusion plate 203 for extruding sintered coal gangue hollow brick raw materials is installed at the end of the first telescopic rod 202 away from the compression cylinder 201. The extrusion plate 203 must withstand huge pressure and friction when pressing the hollow brick blank. Hard alloy materials, such as tungsten cobalt hard alloys (YG type), are used, with a hardness of 86-93 HRA and extremely high wear resistance. This material can ensure that the mold maintains dimensional accuracy during frequent pressing processes, reducing the frequency of maintenance and replacement. When the compression cylinder 201 is activated, the first telescopic rod 202 extends, driving the extrusion plate 203 and the hollow brick circular preparation insert 204 to move towards the rectangular groove 5. Finally, the extrusion plate 203 extrudes the raw materials for preparing sintered coal gangue hollow bricks. A waste material collection box 205 is provided on the top of the extrusion plate 203. Some excess raw materials are extruded into the waste material collection box 205 through the hollow brick circular preparation insert 204. A second motor 6 is provided inside the extrusion plate 203. The output shaft of the second motor 6 is connected to a gear disk 601. When the second motor 6 is activated, the output shaft of the second motor 6 drives the gear disk 601 to rotate, and the gear disk 601 drives the hollow brick circular preparation insert 204 to rotate.

[0027] A hollow brick circular preparation insert 204 is connected to the side of the extrusion plate 203. The outer periphery of the hollow brick circular preparation insert 204 has teeth that mesh with the gear disk 601, and the hollow brick circular preparation insert 204 is rotatably connected to the extrusion plate 203. To ensure smooth demolding of the formed hollow brick blank, the surface friction coefficient of the hollow brick circular preparation insert 204 material must be low. A coating treatment can be applied to the mold surface, such as using a polytetrafluoroethylene coating, which has an extremely low friction coefficient, enabling easy demolding of the brick blank and further improving the wear resistance of the mold. The hollow brick circular preparation insert 204 has a crossbar 3 connected inside. A first hollow column 301 is installed at the bottom of the crossbar 3. A first spring 307 is installed inside the first hollow column 301. A movable column 302 is connected to the end of the first spring 307 away from the crossbar 3. A first motor 303 is installed at the bottom of the movable column 302. A rotating column 304 is connected to the output shaft of the first motor 303. A V-shaped rotating frame 305 is installed on the outer periphery of the rotating column 304. A scraper 306 is installed at the bottom of the rotating column 304. When the first motor 303 is turned on, the output shaft of the first motor 303 drives the rotating column 304 to rotate. The rotating column 304 drives the V-shaped rotating frame 305 and the scraper 306 to rotate. The V-shaped rotating frame 305 and the scraper 306 cut the raw material.

[0028] A rectangular groove 5 is installed at the bottom of the lower support plate 104. The raw materials for preparing sintered coal gangue hollow bricks are added into the rectangular groove 5. A partition plate 501 and a discharge port 502 are installed at the bottom of the rectangular groove 5. After a certain period of time, the extrusion plate 203 and the hollow brick circular preparation rod 204 are raised. The raw materials are pressed into hollow bricks and can be taken out through the rectangular groove 5. The partition plate 501 can be pulled out and the remaining raw materials fall into the discharge port 502 for recycling. A fixed seat 101 is installed at the bottom of the support frame 1. A power box 102 and a control seat 103 are provided on the side of the support frame 1.

[0029] Working principle

[0030] In use, the sintered coal gangue hollow brick preparation device first adds the raw materials for sintered coal gangue hollow brick preparation into a rectangular trough 5. Then, the compression cylinder 201 is activated, extending the first telescopic rod 202 and moving the extrusion plate 203 and the hollow brick circular preparation rod 204 towards the rectangular trough 5. Finally, the extrusion plate 203 extrudes the raw materials for sintered coal gangue hollow brick preparation. The first motor 303 is then activated, and its output shaft drives the rotating column 304 to rotate. The rotating column 304 drives the V-shaped rotating frame 305 and the scraper 306 to rotate, cutting the raw materials. Excess material is extruded into the waste material collection box 205 through the hollow brick circular preparation rod 204. After a certain period, the extrusion plate 203 and the hollow brick circular preparation rod 204... When the insert rod 204 is raised, the raw material is pressed into hollow bricks. The hollow bricks can be removed through the rectangular slot 5, and the partition 501 can be pulled out. The remaining raw material falls into the discharge port 502 for recycling. After the hollow brick circular preparation insert rod 204 is raised, the second telescopic rod 401 extends, and the connecting plate 402 drives the scraper 405 to move towards the hollow brick circular preparation insert rod 204. Due to the action of the second spring 408, the scraper 405 is in full contact with the hollow brick circular preparation insert rod 204. The second motor 6 is turned on, and the output shaft of the second motor 6 drives the gear disk 601 to rotate. The gear disk 601 drives the hollow brick circular preparation insert rod 204 to rotate, and the residual material on the surface of the hollow brick circular preparation insert rod 204 is scraped off and falls into the recycling box 406. The recycling box 406 can be removed for cleaning.
