Description

Technical Field

[0001] The utility model relates to the technical field of producing cement materials, in particular to an iron removal device for a raw material grinding and separator. Background Art

[0002] The raw material grinding mill utilizes a CLF200*140 roller compactor system. During production, material exiting the rollers enters the V-separator, where it is carried by the rising airflow to the powder separator. After being dispersed by primary, secondary, and tertiary airflow, it enters the rotor of the powder concentrator. Dust particles moving in the vortex are simultaneously affected by gravity, wind, and centrifugal forces. Fine particles are drawn into the rotor with the airflow and flow out of the air duct into a cyclone for collection as the finished product. The powder collides with the rotating blades and falls into the return chute below the rotor. From there, it enters the roller compactor for secondary grinding. During grinding, the equipment can contain small iron fragments, which can easily damage the equipment. Therefore, a deironing device for the raw material concentrator is used to remove iron from the material before it enters the grinding equipment.

[0003] Existing technologies include the utility model with publication number CN215744063U, which discloses an iron removal device for a raw mill powder classifier. The patent adopts a powder return chute, one end of which is connected to the discharge port of the powder classifier, and the other end of the powder return chute is connected to the feed port of the raw mill. The powder return chute is provided with a support plate, a baffle and a driving mechanism for driving the support plate and the baffle to rotate in opposite directions. The support plate and the baffle are both hinged to the powder return chute, and the driving mechanism is fixedly connected to the powder return chute. An iron cutting adsorption component is provided on the support plate, and an iron removal port is provided at the position corresponding to the powder return chute and the baffle. The support plate is located above the baffle, and the driving mechanism is electrically connected to the PLC controller. The utility model equipment solves the problem in the prior art that it is difficult to separate the material from the iron block, causing damage to the raw mill.

[0004] In daily work, when grinding materials entering the equipment, there is a problem that the equipment passes through a pipeline before grinding the materials. Generally, the materials pass through the pipeline at will into the grinding equipment for grinding. However, there is iron in the materials, and the materials containing iron enter the grinding equipment together and cause damage to the interior of the equipment. Utility Model Content

[0005] The purpose of the utility model is to solve the defect in the prior art that the raw mill is damaged by iron blocks contained in the material, and to propose an iron removal device for a raw mill separator.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a raw material grinding and selecting machine iron removal device, comprising a feed hopper, a pipeline and an iron-absorbing device, the lower surface of the feed hopper is fixedly connected to the pipeline, the iron-absorbing device is arranged inside the pipeline, the iron-absorbing device comprises an electromagnetic plate and a rotating plate, the electromagnetic plate is arranged inside the pipeline, the internal rotation of the pipeline is connected to the rotating plate, one end of the electromagnetic plate is fixedly connected to a sliding rod, the end of the sliding rod away from the electromagnetic plate is fixedly connected to the connecting plate, the side of the pipeline is fixedly connected to a limiting block, the internal sliding connection of the limiting block is connected to a clamping rod, the surface of the sliding rod is provided with a clamping hole, the clamping rod is clamped with the inside of the clamping hole, one end of the clamping rod is fixedly connected to a weight block, the side of the rotating plate is provided with a pressing groove, and the interior of the pipeline is provided with a limiting hole.

[0007] Furthermore, the internal sliding connection of the pressing groove is connected to a limiting rod, one end of which is engaged with the inside of the limiting hole. By setting the limiting rod, the rotating plate can be limited, which reduces the risk that the rotating plate will easily rotate inside the pipeline when the equipment is in use, causing the material to easily flow out through the opened rotating plate when unloading.

[0008] Furthermore, one end of the limiting rod is fixedly connected to a spring, and the end of the spring away from the limiting rod is fixedly connected to the inner wall of the pressing groove. The spring is provided to facilitate applying a reset elastic force to the limiting rod.

[0009] Furthermore, one end of the limiting rod is fixedly connected to a pressure rod, and the pressure rod is slidably connected to the inner wall of the limiting hole. The pressure rod is provided to facilitate the movement of the limiting rod.

[0010] Furthermore, a collecting device is provided on the side of the pipe, and the collecting device includes a collecting box and a fixed block. The collecting box is provided on one side of the pipe, and the fixed block is fixedly connected to the side of the pipe. A connecting arm is fixedly connected to the side of the collecting box, and the connecting arm is plug-connected to the interior of the fixed block. The surface of the fixed block is fixedly connected to the connecting block. By providing the collecting box, the iron adsorbed on the surface of the electromagnetic plate can be collected, which reduces the risk of iron on the surface of the electromagnetic plate being randomly scattered when the equipment is in use, causing pollution around the equipment.

[0011] Furthermore, a connecting rope is fixedly connected to the surface of the connecting block, and an end of the connecting rope away from the connecting block is fixedly connected to a connecting head. The connecting rope is provided to facilitate connection of the pin.

[0012] Furthermore, one end of the connector is fixedly connected to a latch, and the latch is plug-connected to the interior of the fixing block and the connecting arm. The provision of the latch facilitates fixing the connecting arm and the fixing block.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] When the material is in the hopper, the user pushes the material into the inner wall of the pipe, and the material passes through the pipe to be ground inside the grinding device. When the device is in use, the user presses the pressure rod, and the pressure rod moves to drive the limit rod to move. When the limit rod moves, the spring displacement deformation generates elastic force, and the limit rod moves out of the limit hole, the rotating plate loses its restraint, and then moves the clamping rod upward, and then the clamping rod moves out of the inside of the clamping hole, and then the slide bar loses its restraint and moves the slide bar to drive the electromagnetic plate to move against the rotating plate, and then the electromagnetic plate is separated from the inside of the pipe. By arranging the iron absorption device, it effectively absorbs the iron in the material flowing inside the pipe, and plays the role of removing iron from the material. Before the material is ground, the device passes through the pipe, and generally the material passes through the pipe at will into the grinding device for grinding. However, there is iron in the material, and the material with iron enters the grinding device together, causing damage to the inside of the device, thereby improving the practicality of the device.

[0015] 2. In the present invention, by providing a collecting device, when the equipment is in use, the user pulls the connecting rope, and the connecting rope moves to drive the connecting head to move, and the connecting head drives the pin to move and disengage from the connecting arm and the inside of the fixed block, and then the connecting arm loses its restraint, and the collecting box is pulled to drive the connecting arm to disengage from the inside of the fixed block. By providing a collecting device, the iron on the surface of the electromagnetic plate is effectively collected, which plays a role in collecting the iron adsorbed on the surface of the electromagnet. After the equipment has been used for a long time, the surface of the electromagnetic plate is prone to adsorb more iron. Generally, the pipe on one side of the electromagnetic plate of the equipment is cleaned around the pipe at random, which easily causes pollution around the pipe, thereby improving the cleanliness of the equipment.

One end of the clamping rod 36 is fixedly connected to the weight block 313, and the side of the rotating plate 37 is provided with a pressing groove 39. The inside of the pipe 2 is provided with a limiting hole 38.

[0025] Specifically, the interior of the pressing groove 39 is slidably connected to the limiting rod 310 , and one end of the limiting rod 310 is engaged with the interior of the limiting hole 38 .

[0026] In this embodiment: by setting a limit rod 310, the rotating plate 37 can be limited, which reduces the risk that the rotating plate 37 will easily rotate inside the pipe 2 when the equipment is in use, causing the material to easily flow out through the opened rotating plate 37 when unloading.

[0027] Specifically, one end of the limiting rod 310 is fixedly connected to a spring 312 , and the end of the spring 312 away from the limiting rod 310 is fixedly connected to the inner wall of the pressing groove 39 . The spring 312 is provided to facilitate applying a reset elastic force to the limiting rod 310 .

[0028] Specifically, one end of the limiting rod 310 is fixedly connected to a pressing rod 311 , and the pressing rod 311 is slidably connected to the inner wall of the limiting hole 38 . The pressing rod 311 is provided to facilitate the movement of the limiting rod 310 .

[0029] In this embodiment: a collecting device 4 is provided on the side of the pipe 2, and the collecting device 4 includes a collecting box 41 and a fixing block 42. The collecting box 41 is provided on one side of the pipe 2, and the fixing block 42 is fixedly connected to the side of the pipe 2. A connecting arm 43 is fixedly connected to the side of the collecting box 41, and the connecting arm 43 is plugged into the inside of the fixing block 42. A connecting block 44 is fixedly connected to the surface of the fixing block 42.

[0030] In this embodiment, by providing a collection box 41, the iron adsorbed on the surface of the electromagnetic plate 31 can be collected, thereby reducing the risk of iron on the surface of the electromagnetic plate 31 being randomly scattered when the device is in use, causing pollution around the device.

[0031] Specifically, a connecting rope 45 is fixedly connected to the surface of the connecting block 44 , and a connecting head 46 is fixedly connected to one end of the connecting rope 45 away from the connecting block 44 .

[0033] Working principle: When the equipment is in use, the user passes the material through the hopper 1 into the inner wall of the pipe 2, and then the material is ground inside the equipment through the pipe 2. When the equipment is in use, the user presses the pressure rod 311, and then the pressure rod 311 moves to drive the limit rod 310 to move. When the limit rod 310 moves, it drives the spring 312 to move and deform to generate elastic force, and then the limit rod 310 moves out of the inside of the limit hole 38, and the rotating plate 37 loses its restraint, and then moves the clamping rod 36 upward, and then the clamping rod 36 moves out of the inside of the clamping hole 35, and then the slide rod 3 2 loses its restraint and the sliding rod 32 drives the electromagnetic plate 31 to move against the rotating plate 37, and then the electromagnetic plate 31 is separated from the inside of the pipe 2. By setting the iron-absorbing device 3, the iron in the material flowing inside the pipe 2 is effectively absorbed, which plays a role in removing iron from the material. Before the equipment grinds the material, it passes through the pipe 2. Generally, the material passes through the pipe 2 and enters the grinding equipment for grinding at will. However, there is iron in the material. The material with iron enters the grinding equipment together and causes damage to the interior of the equipment, thereby improving the practicality of the equipment.

[0034] When the device is in use, the user pulls the connecting rope 45, and the connecting rope 45 moves to drive the connecting head 46 to move, and the connecting head 46 drives the pin 47 to move out of the connecting arm 43 and the inside of the fixed block 42, and then the connecting arm 43 loses its restraint, and the collecting box 41 is pulled to drive the connecting arm 43 out of the inside of the fixed block 42. By setting up the collecting device 4, the iron on the surface of the electromagnetic plate 31 is effectively collected, which plays a role in collecting the iron adsorbed on the surface of the electromagnet. After the device has been used for a long time, the surface of the electromagnetic plate 31 is prone to adsorb more iron. Generally, the pipe 2 on one side of the electromagnetic plate 31 of the device is cleaned around the pipe 2 at will, which easily causes pollution around the pipe 2, thereby improving the cleanliness of the device.
