Description

Technical Field

[0001] The utility model relates to the technical field of material processing equipment, and more specifically, to a hoisting sieving and iron removing equipment. Background Art

[0002] Sieving and iron removing equipment is mainly used in industrial production and material processing to remove ferromagnetic impurities in raw materials, ensuring the smooth progress of subsequent processes and product quality. This type of equipment combines screening and magnetic separation technologies, which can effectively separate materials of different particle sizes and remove iron contaminants.

[0003] The current sieving and iron removing equipment still has the following problems:

[0004] 1. When the sieving equipment and the iron removing equipment are in use, since the equipment is placed on the ground, a material conveying device is used for material conveyance. However, using the conveying device not only increases the floor area occupied by the equipment, but also, since the conveyed material contains magnetic substances, the material may be adsorbed on the conveying device.

[0005] 2. After the iron removing device has been used for a period of time, the magnetic bar needs to be manually pulled out to clean the magnetic substances adsorbed on the magnetic bar to avoid a decrease in iron removing efficiency due to excessive magnetic substances. However, manually cleaning the iron removing device not only increases the labor intensity of the workers, but also requires cleaning from top to bottom in sequence, and the process is too cumbersome.

[0006] 3. When cleaning the magnetic bar, the magnetic bar is pulled out from the iron removing device, and the magnetic substances will come into contact with the inner wall of the iron removing device and then fall off, and then fall to the bottom cleaning port and be discharged. However, since the magnetic bar cannot be completely pulled out from its interior, there will be a situation where magnetic substances remain at the end. Although some magnetic bars can be completely pulled out from the interior of the iron removing device to clean the residual magnetic substances at the end, since there are multiple magnetic bars, aligning and reinstalling them will make the process too cumbersome.

[0007] Therefore, it is necessary to propose a hoisting sieving and iron removing equipment to solve the above problems. Content of the Utility Model

[0032] Please refer to Figure 1-6 , a hoisting and sieving iron removal device, including a hoisting frame 101, a hook 102, a straight-through sieve 103, an iron removal device 104, a pneumatic slide gate valve 105 and a connecting pipe 106. Specifically, an upper plate and a lower plate are provided on the hoisting frame 101. The straight-through sieve 103 is installed on the top of the lower plate through a fixing member. The iron removal device 104 is installed at the bottom of the lower plate. The discharge pipe at the bottom of the straight-through sieve 103 extends into the iron removal device 104. The pneumatic slide gate valve 105 is fixed on the upper plate, and the output end is connected to the connecting pipe 106. The connecting pipe 106 is fixed on the upper plate. The top of the output end of the pneumatic slide gate valve 105 is connected to a feeding device. The bottom of the output end of the pneumatic slide gate valve 105 is connected with a connecting pipe 106. The bottom of the connecting pipe 106 extends into the straight-through sieve 103. The straight-through sieve 103, the iron removal device 104 and the pneumatic slide gate valve 105 are existing mature devices and will not be elaborated here too much. The pneumatic slide gate valve 105, the straight-through sieve 103 and the iron removal device 104 are fixed on the hoisting frame 101. The straight-through sieve 103 and the iron removal device 104 are connected. A lifting ring is provided at the top of the hoisting frame 101, and the lifting ring is located on the upper plate. The device is fixed on a building or at the bottom of the discharge port of other equipment through the hook 102, so as to directly add materials into the straight-through sieve 103. The bottom end of the hook 102 is installed on the lifting ring, and the top end is fixed on the building through a steel wire rope;

[0033] Refer to Figure 2 , an iron removal area 107 and a cleaning area 108 are provided inside the iron removal device 104. The materials entering the iron removal device 104 will enter the iron removal area 107. The feed inlet of the iron removal device 104 is located at the position between the cleaning area 108 and the iron removal area 107. When the materials fall, they will fall on the middle position of the magnetic bars 111, so that no magnetic substances will be adsorbed on the ends of the magnetic bars 111. At least one row of cylinders 109 is provided at both ends of the shell of the iron removal device 104. Multiple rows of outer plates 110 are provided on the iron removal device 104. Multiple magnetic bars 111 are connected to each row of outer plates 110. The multiple magnetic bars 111 can improve the iron removal efficiency. The cleaning assembly 113 corresponds to the position of each magnetic bar 111;

[0034] Specifically, when the straight-line sieve 103 and the iron removal device 104 are suspended by the hoisting frame 101, the magnetic bars 111 can be cleaned by the air cylinders 109, saving manpower. The output ends of each pair of air cylinders 109 are connected with outer plates 110. The magnetic bars 111 extending into the iron removal area 107 and the cleaning area 108 are installed on the outer plates 110. The other ends of the magnetic bars 111 are connected with inner plates 112. The inner plates 112 are used to support the other ends of multiple magnetic bars 111 and at the same time used to push the trigger plate 116 to move;

[0035] Specifically, referring to Figure 4 and Figure 5 , when the magnetic bar 111 is pulled out from the iron removal device 104, the inner plate 112 will come into contact with the cleaning component 113. First, the trigger plate 116 will be squeezed by the strip plate 124. At this time, the trigger plate 116 will drive the baffle 121 to move towards the other end. At this time, the convex block 119 will slide in the sliding groove 118, so as to push the symmetrical arc-shaped scraping plates 117 to rotate along the magnetic bar 111, so as to scrape off the magnetic substances on the outer wall of the magnetic bar 111. The cleaning area 108 is provided with a cleaning component 113, and the cleaning component 113 is fixed on the inner wall of the iron removal device 104;

[0036] Referring to Figure 4 and Figure 5 , the magnetic bar 111 passes through the middle of the cleaning component 113. The cleaning component 113 includes a fixed seat 114, a guide frame 115, a trigger plate 116 and symmetrical arc-shaped scraping plates 117. One end of the guide frame 115 is provided with an inclined surface. When the magnetic bar 111 slides in the guide frame 115, the magnetic substances will be guided by the inclined surface and move to the bottom of the magnetic bar 111. Subsequently, the rotation of the arc-shaped scraping plates 117 can scrape off the magnetic substances at the bottom. Although when the materials are stacked at the bottom, they will be separated from the magnetic bar 111 due to the action of gravity, the arc-shaped scraping plates 117 can scrape off the last part of the magnetic substances, improving the cleaning effect. The arc-shaped scraping plates 117 are made of magnetic shielding materials and have the function of blocking magnetic force. The guide frame 115 is fixed at one end of the fixed seat 114. Guide grooves are provided on both sides of the guide frame 115. The arc-shaped scraping plates 117 are located in the guide grooves. The trigger plate 116 is axially slidably connected to the tops of the guide frame 115 and the arc-shaped scraping plates 117. When the trigger plate 116 moves, the convex blocks 119 on both sides are pushed to extend outwards through the movement of the convex blocks 119 in the sliding grooves 118. Inclined sliding grooves 118 are provided on the outer ring surfaces of the arc-shaped scraping plates 117, and convex blocks 119 corresponding to the sliding grooves 118 are provided on the inner ring surfaces of the trigger plate 116. The convex blocks 119 slide in the sliding grooves 118;

[0037] Referring to Figure 5 and Figure 6, a cavity 120 is provided between the fixed seat 114 and the guide frame 115. A baffle 121 on one side of the trigger plate 116 is located inside the cavity 120. Springs 122 are connected between the baffle 121 and the side wall of the cavity 120. Through the push of the springs 122, the trigger plate 116 can extend out from the guide frame 115. One end of the trigger plate 116 is connected to a baffle 121 located inside the cavity 120, and a spring 122 is connected between the baffle 121 and the fixed seat 114.

[0038] Specifically, referring to Figure 5 and Figure 6 , a guide rail 123 is provided in the guide groove. The guide rail 123 is used to stabilize the movement of the arc-shaped scraper 117. Grooves corresponding to the guide rail 123 are provided on both sides of the arc-shaped scraper 117. The guide rail 123 is fixed on the guide frame 115 and the fixed seat 114, and the arc-shaped scraper 117 is slidably connected to the guide rail 123.

[0039] Specifically, referring to Figure 5 , one end of the trigger plate 116 is connected to a strip plate 124. When not triggered, the trigger plate 116 will overlap with the guide frame 115, facilitating the movement of magnetic substances from the inclined surface on one side. The strip plate 124 can come into contact with the inner plate 112.

[0040] Specifically, referring to Figure 5 , the top of the fixed seat 114 is connected with a cover plate 125. The cover plate 125 covers the top of the cavity 120 and the trigger plate 116, which is used to prevent materials from entering the cavity 120 and has the function of protecting the internal components. The cover plate 125 is located on the top of the trigger plate 116.

[0041] In this embodiment, the straight-through sieve 103, the iron removal device 104, and the pneumatic slide valve 105 are fixed on the lifting frame 101. The lifting frame 101 is suspended at the bottom of the feeding device through a hook 102, facilitating the materials in the feeding device to be directly put into the straight-through sieve 103 through the connecting pipe 106. The bottom of the straight-through sieve 103 is provided with a discharge pipeline, and this discharge pipeline extends into the iron removal device 104. The materials screened by the straight-through sieve 103 will directly enter the iron removal device 104. Multiple horizontally arranged magnetic rods 111 are provided in the iron removal device 104. The materials will flow between the multiple magnetic rods 111, and the magnetic substances in the materials will be attracted by the magnetic rods 111 and thus adhere to the outer wall of the magnetic rods 111. The materials passing through the magnetic rods 111 will be discharged from the discharge port at the bottom. At the same time, another discharge port is provided on the side wall of the straight-through sieve 103 for discharging the materials that do not pass through the sieve mesh of the straight-through sieve 103.

[0042] When the iron removal device 104 needs to be cleaned after being used for a period of time, the cylinders 109 on both sides of the iron removal device 104 are started, and the symmetrical cylinders 109 act synchronously. The output end drives the outer plate 110 to move to one side, and the outer plate 110 pulls out the magnetic bars 111 connected above from the iron removal device 104. As a result, the magnetic substances on the outer wall of the magnetic bars 111 will move from the iron removal area 107 to the cleaning area 108, and will come into contact with the cleaning components 113 on the inner wall of the iron removal device 104. The cleaning components 113 scrape off the magnetic substances on them. The inclined surface on one side of the guide frame 115 guides the magnetic substances to the bottom, so that most of the magnetic substances accumulate at the bottom. A large amount of magnetic substances fall to the bottom cleaning port due to the action of gravity. When the inner plate 112 comes into contact with the cleaning components 113, it means that the entire magnetic bar 111 is about to be cleaned. At this time, the inner plate 112 squeezes the trigger plate 116 through the strip plate 124. When the trigger plate 116 moves, through the movement of the convex block 119 in the sliding groove 118, the arc-shaped scraping plate 117 can be rotated along the axis. Through the synchronous rotation of the two arc-shaped scraping plates 117 towards the bottom, the magnetic substances at the bottom can be scraped off. At the same time, the arc-shaped scraping plate 117 is made of a magnetic shielding material. When the arc-shaped scraping plates 117 converge at the bottom, the arc-shaped scraping plates 117 can block the magnetic force between the magnetic material and the magnetic bar 111, so that the magnetic material falls off.

[0043] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
