Description

Technical Field

[0001] This utility model relates to the field of casting production technology, specifically a recycling magnetic separator for casting production. Background Technology

[0002] During the casting process, a small amount of iron impurities may be mixed into the molding sand raw material. If these iron impurities are not removed when the molding sand is reused, they will affect the surface quality of the subsequent castings. Therefore, it is necessary to separate the iron impurities in the recycled molding sand using a recycling magnetic separator. In the prior art, patent CN 218050172 U discloses a recycling magnetic separator for casting production, including a magnetic separator box. The top of the magnetic separator box has an inlet, and both ends have a first outlet and a second outlet. The second outlet is close to the inlet. The bottom of the magnetic separator box has four bases, each with a vibration device. One base has a motor on top. The magnetic separator box has a touch screen located on one side of the motor and near the second outlet. A recycling separation device is installed inside the magnetic separator box. This invention, by setting up a recycling separation device, not only simplifies the structure but also adds a vibration device, making recycling more efficient and easier to use. While more convenient, this device separates iron impurities from molding sand using the same conveyor belt. This means that the device cannot continue magnetic separation of iron impurities from molding sand while conveying the separated iron impurities, resulting in a decrease in the device's own molding sand magnetic separation recovery efficiency. At the same time, when the casting production raw materials are fed into the device, they accumulate on the conveyor belt below the inlet. This accumulation causes mutual gravitational compression of the casting production raw materials, which may lead to iron impurities in the casting production raw materials overcoming the subsequent magnetic separation force, resulting in poor magnetic separation effect of iron impurities in the casting production raw materials. Therefore, we propose a recovery-type magnetic separator for casting production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a recycling magnetic separator for casting production. The device uses two sets of conveying elements to work together to discharge and convey the magnetically separated iron impurities and the magnetically separated casting raw materials under the action of a magnetic field, thereby improving the magnetic separation and recovery efficiency of molding sand. At the same time, the device uses a guiding element to ensure that the casting raw materials are spread relatively evenly on the conveying elements in the longitudinal direction, thereby improving the separation rate of iron impurities in the casting raw materials. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a recycling magnetic separator for casting production, comprising a housing, a support frame at the bottom of the housing, and a magnetic separation mechanism;

[0005] Magnetic separation mechanism: It includes belt conveyor one, belt conveyor two, magnetic plate, feeding dispersion component, auxiliary component and dust removal component. Belt conveyor one is located at the lower end between the front and rear walls of the outer shell. Belt conveyor two is located at the upper right end between the front and rear walls of the outer shell. Magnetic plate is installed inside belt conveyor two. Feed dispersion component is installed on the top wall of the outer shell. Auxiliary component is installed inside the outer shell. Dust removal component is installed on the front wall of the outer shell. This device, through the cooperation of two sets of conveying elements, can discharge and convey the magnetically separated iron impurities and the magnetically separated casting raw materials under the action of magnetic field, thereby improving the molding sand magnetic separation and recovery efficiency. At the same time, the device, through the material guiding element, allows the casting raw materials to be spread more evenly longitudinally on the conveying element, thereby improving the iron impurity separation rate of the casting raw materials.

[0006] Furthermore, it also includes a microcontroller, which is located outside the housing. The input terminal of the microcontroller is electrically connected to an external power supply, and the output terminal of the microcontroller is electrically connected to the input terminals of belt conveyor one and belt conveyor two, respectively, to facilitate the control of electrical components inside the device.

[0007] Furthermore, the magnetic separation mechanism also includes a first baffle and a second baffle. The first baffle is located at the front and rear ends of the upper side of the housing of the first belt conveyor, and the second baffle is located at the front and rear ends of the lower side of the housing of the second belt conveyor. The second baffle is used to longitudinally deflect and intercept the material movement in the corresponding conveyor of the recycling magnetic separator used for casting production.

[0008] Furthermore, the feeding and dispersing assembly includes a feeding shell, a conical hopper, and a distribution pipe. The feeding shell is disposed through the left end of the top wall of the outer shell, and the lower end of the feeding shell is provided with a conical hopper. The conical bottom wall of the conical hopper is provided with a longitudinally uniformly distributed distribution pipe, so that the casting production raw materials can be spread relatively evenly longitudinally onto the conveying element.

[0009] Furthermore, the auxiliary components include a fixed seat and a guide seat. The guide seat is horizontally and evenly arranged between the front and rear walls of the outer shell through the fixed seat. The upper side of the guide seat slides in contact with the lower side of the outer arc surface of the belt of the second belt conveyor, thereby improving the separation rate of iron impurities separated from the raw materials in the casting production.

[0010] Furthermore, the dust removal assembly includes an air pipe, a main pipe, an industrial vacuum cleaner, and a connecting pipe. The industrial vacuum cleaner is located outside the housing. The front wall of the housing is provided with horizontally evenly distributed air pipes. A main pipe is provided between the air pipes. The left end of the main pipe is connected to the suction port of the industrial vacuum cleaner through a connecting pipe. The input end of the industrial vacuum cleaner is electrically connected to the output end of the microcontroller to avoid dust overflow from the discharge port of the recycling magnetic separator used in casting production.

[0011] Furthermore, the magnetic separation mechanism also includes a discharge assembly, which includes a recycling discharge shell and a magnetic material chute. The magnetic material chute is disposed through the right wall of the outer shell, and the recycling discharge shell is disposed through the right end of the bottom wall of the outer shell, which guides the discharge of molding sand and separated iron impurities after impurity removal in the recycling magnetic separator used for casting production.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This recycling magnetic separator for casting production has the following advantages:

[0013] 1. When using a recycling magnetic separator for casting production, the device uses two sets of conveying elements to work together. Under the action of a magnetic field, the magnetically separated iron impurities and the magnetically separated casting raw materials can be discharged and conveyed separately. There is no need to convey the magnetically separated iron impurities and the magnetically separated casting raw materials one by one through a single conveyor belt, thereby improving the efficiency of molding sand magnetic separation and recovery.

[0014] 2. When using a recycling-type magnetic separator for casting production, the device uses a material guiding element to ensure that the casting production raw materials are evenly spread longitudinally onto the conveying element. This reduces the thickness of the material accumulation when the casting production raw materials enter the magnetic separation section, thereby reducing the interference of gravity compression between materials caused by excessive material accumulation on the subsequent magnetic separation of iron impurities and improving the iron impurity separation rate of the casting production raw materials.

[0015] 3. When using a recycling magnetic separator for casting production, the dust generated during the magnetic separation and recycling of casting raw materials is absorbed by the dust removal components, reducing the degree of dust overflow from the outlet of the device.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a recycling magnetic separator for casting production, including a housing 1, a support frame at the bottom of the housing 1, a single-chip microcomputer 2 located outside the housing 1, the input end of the single-chip microcomputer 2 being electrically connected to an external power supply, and a magnetic separation mechanism 3.

[0022] Magnetic separation mechanism 3: It includes belt conveyor 31, belt conveyor 33, magnetic plate 35, feeding dispersion component 36, auxiliary component 37 and dust removal component 38. The magnetic plate 35 can be made of neodymium iron boron. Belt conveyor 31 is located at the lower end between the front and rear walls of the outer shell 1. Belt conveyor 33 is located at the upper right end between the front and rear walls of the outer shell 1. Magnetic plate 35 is located inside belt conveyor 33. Feed dispersion component 36 is located on the top wall of the outer shell 1. Auxiliary component 37 is located inside the outer shell 1. Dust removal component 38 is located on the front wall of the outer shell 1. The output end of microcontroller 2 is electrically connected to the input end of belt conveyor 31 and belt conveyor 33 respectively.

[0023] The magnetic separation mechanism 3 also includes a discharge assembly 39, which includes a recycling discharge shell 391 and a magnetic material chute 392. The magnetic material chute 392 is disposed through the right wall of the outer shell 1, and the recycling discharge shell 391 is disposed through the right end of the bottom wall of the outer shell 1.

[0024] Microcontroller 2 starts belt conveyor 31, which operates and magnetically transports the casting raw materials from left to right through the contact friction between its belt and the raw materials. Simultaneously, microcontroller 2 starts belt conveyor 33, and magnetic plate 35 generates its own magnetic field. This magnetic field covers the belt of belt conveyor 31 below it, creating a magnetic attraction force. When the casting raw materials move into the magnetic field of magnetic plate 35, the magnetic attraction causes iron impurities within the raw materials to separate vertically upwards. The separated iron impurities are attracted to the lower outer arc surface of the belt of belt conveyor 33. These separated iron impurities are then further separated by the contact friction with the belt of belt conveyor 33, thus moving upwards with the belt. The bottom of the belt of conveyor 2 33 moves from left to right. The iron impurities separated by magnetic separation move out of the magnetic field range of magnetic plate 35 along with the belt of conveyor 2 33 and fall onto magnetic material chute 392 under the action of gravity. The iron impurities separated by magnetic separation of casting raw materials are collected by the right end of the inclined surface of magnetic material chute 392. The casting raw materials after impurity separation fall onto the recovery discharge shell 391 under the action of gravity by the right end of belt of conveyor 1 31. The casting raw materials after iron impurity removal are recovered by the bottom of recovery discharge shell 391. The device can discharge and transport the magnetically separated iron impurities and the magnetically separated casting raw materials separately under the action of magnetic field through the cooperation of two sets of conveying elements, thereby improving the magnetic separation recovery efficiency of molding sand.

[0025] The magnetic separation mechanism 3 also includes a first baffle 32 and a second baffle 34. The first baffle 32 is located at the front and rear ends of the upper side of the housing of the first belt conveyor 31, and the second baffle 34 is located at the front and rear ends of the lower side of the housing of the second belt conveyor 33. During the magnetic separation of casting production raw materials, the first baffle 32 is used to longitudinally deflect and intercept the casting production raw materials on the belt of the first belt conveyor 31 that move to the right, and the second baffle 34 is used to longitudinally deflect and intercept the iron impurities on the second belt conveyor 33 that move to the right.

[0026] The feeding dispersion assembly 36 includes a feeding shell 361, a conical hopper 362, and a distribution pipe 363. The feeding shell 361 is disposed through the left end of the top wall of the outer shell 1. The lower end of the feeding shell 361 is provided with the conical hopper 362. The conical bottom wall of the conical hopper 362 is provided with longitudinally evenly distributed distribution pipes 363. When using the device to perform magnetic separation and recovery of casting production raw materials, the casting production raw materials consist of crushed molding sand and a small amount of iron impurities. First, the casting production raw materials are transported into the feeding shell 361 by an external conveyor. The casting raw materials of 361 enter the conical bottom of the conical hopper 362 by their own gravity along the feed shell 361. Then, the casting raw materials fall longitudinally and spread evenly on the belt of the belt conveyor 31 through the corresponding distribution pipe 363. By dispersing the material, the phenomenon of excessive accumulation of casting raw materials on the belt of the belt conveyor 31 is avoided. The device, through the material guiding element, enables the casting raw materials to be spread more evenly longitudinally on the conveying element, thereby improving the iron impurity separation rate of the casting raw materials.

[0027] The auxiliary component 37 includes a fixed seat 371 and a guide seat 372. The guide seat 372 is horizontally and evenly arranged between the front and rear walls of the outer shell 1 through the fixed seat 371. The upper side of the guide seat 372 slides in contact with the lower side of the outer arc surface of the belt of the second belt conveyor 33. When the adsorbed iron impurities pass through the guide seat 372, the protruding design of the guide seat 372 causes the horizontal rightward movement trajectory of the iron impurities to change vertically. This vertical drop change causes the position of the magnetically moved iron impurities to change relative to each other. Then, through this position change, the molding sand that may be carried in the iron impurities is separated out and falls back onto the belt of the first belt conveyor 31 under the action of gravity.

[0028] The dust removal assembly 38 includes an air pipe 381, a main pipe 382, ​​an industrial vacuum cleaner 383, and a connecting pipe 384. The industrial vacuum cleaner 383 is located outside the outer casing 1. The front wall of the outer casing 1 is perforated by horizontally evenly distributed air pipes 381. The main pipe 382 is located between the air pipes 381. The left end of the main pipe 382 is connected to the suction port of the industrial vacuum cleaner 383 via the connecting pipe 384. The input end of the industrial vacuum cleaner 383 is electrically connected to the output end of the microcontroller 2. During the magnetic separation process of raw materials in casting production, the single... The chip 2 starts the industrial vacuum cleaner 383. The industrial vacuum cleaner 383 consists of a motor, a filtration system, a dust can / collection bin, a suction hose and accessories. Its core working principle is to generate negative pressure by driving the fan with the motor, forming an air pressure difference. The dust generated during the magnetic separation process of casting production raw materials is absorbed through the connecting pipe 384, the main pipe 382 and the air pipe 381. After being filtered by the filter bag or filter can inside, the clean air is discharged, preventing the dust generated during the magnetic separation process of casting production raw materials from overflowing through the material port.

[0029] The working principle of the recycling magnetic separator for casting production provided by this utility model is as follows: When using the device to magnetically separate and recycle casting production raw materials, the casting production raw materials consist of crushed molding sand and a small amount of iron impurities. First, the casting production raw materials are transported to the feed shell 361 by an external conveyor. The casting production raw materials in the feed shell 361 enter the conical bottom of the conical hopper 362 by their own gravity. Then, the casting production raw materials fall longitudinally dispersedly through the corresponding distribution pipe 363 and are spread evenly on the belt of the belt conveyor 31. The dispersed feeding avoids the phenomenon of excessive accumulation of casting production raw materials on the belt of the belt conveyor 31. At the same time, the microcontroller 2 starts the belt conveyor 31, and the belt conveyor 31 runs. Through the contact friction between its own belt and the casting raw materials, the casting raw materials are magnetically conveyed from left to right. Simultaneously, the microcontroller 2 starts the second belt conveyor 33, and the magnetic plate 35 generates its own magnetic field. This magnetic field covers the belt of the first belt conveyor 31 below it, generating a magnetic attraction force. When the casting raw materials move into the magnetic field of the magnetic plate 35, the magnetic attraction causes iron impurities within the casting raw materials to separate vertically upwards. The separated iron impurities are attracted to the lower side of the outer arc surface of the belt of the second belt conveyor 33. These separated iron impurities, through contact friction with the belt of the second belt conveyor 33, move from left to right along with the bottom of the belt of the second belt conveyor 33. This process... In the process, when the adsorbed iron impurities pass through the guide seat 372, the protruding design of the guide seat 372 causes a vertical change in the lateral rightward trajectory of the iron impurities as they pass through it. This vertical drop causes a positional change among the magnetically attracted iron impurities, which in turn causes the molding sand that may be carried within the iron impurities to separate out and fall back onto the belt of belt conveyor 31 under gravity. The iron impurities separated by magnetic separation are moved to the right by the belt of belt conveyor 33 and move out of the magnetic field range of magnetic plate 35. They then fall onto magnetic material chute 392 under gravity. The right end of the inclined surface of magnetic material chute 392 collects the iron impurities separated by magnetic separation from the casting raw materials. The casting raw materials after impurity separation are then conveyed by belt conveyor. The right end of the conveyor belt of conveyor 31 falls to the recovery discharge shell 391 under its own gravity. The bottom of the recovery discharge shell 391 recovers the casting raw materials after iron impurities have been removed. During the magnetic separation process of the casting raw materials, the microcontroller 2 starts the industrial vacuum cleaner 383. The industrial vacuum cleaner 383 consists of a motor, filtration system, dust cylinder / collection bin, suction hose, and accessories. Its core working principle is to generate negative pressure by driving a fan with a motor, creating an air pressure difference. This air pressure difference is then absorbed by the connecting pipe 384, main pipe 382, ​​and air pipe 381. After filtration through its internal filter bag or filter canister, clean air is discharged, preventing dust generated during the magnetic separation process from overflowing through the material inlet.The casting raw materials on the belt of conveyor belt 31 are longitudinally deflected and intercepted to the right by two baffles 32, and iron impurities on conveyor belt 33 are longitudinally deflected and intercepted to the right by two baffles 34.

[0030] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an MSP430, the belt conveyor 31 and the belt conveyor 33 can both be XY-PS series planar belt conveyors, and the industrial vacuum cleaner 383 can be a CM series three-phase industrial vacuum cleaner. The microcontroller 2 controls the operation of the belt conveyor 31, the belt conveyor 33 and the industrial vacuum cleaner 383 using methods commonly used in the prior art.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
