Description

Technical Field

[0001] This utility model belongs to the field of low-carbon ferrochrome production technology, specifically relating to a low-carbon ferrochrome product grading and screening machine. Background Technology

[0002] Ferrochrome is the most important raw material for the production of stainless steel. It is mainly used in the production of stainless steel, ball bearing steel, tool steel, nitriding steel, heat-resistant steel, tempered steel, carburizing steel, and hydrogen-resistant steel. This is because chromium plays a decisive role in stainless steel; only one element determines the properties of stainless steel, and that is chromium. Every type of stainless steel contains a certain amount of chromium. Based on the carbon content, it can be divided into high-carbon ferrochrome, medium-carbon ferrochrome, and low-carbon ferrochrome.

[0003] The document with application number CN202220192583.2 proposes a grading and screening machine for high-carbon ferrochrome products. It uses a rotary motor to drive multiple sets of pusher plates to rotate, thereby pushing the material in the screening tank. By adjusting the rotation of the motor-driven drive gear and gear disc, the position of different filter screens can be adjusted, thereby achieving the grading and screening of materials.

[0004] The grading and screening device proposed in the aforementioned document can perform screening operations on materials, but because chromite raw materials are relatively hard, during screening, the combined action of the pusher plate and the screen plate can easily cause chromite to get stuck in the through holes of the screen plate, thus blocking the rotation of the pusher plate and causing the pusher plate to malfunction, affecting the normal use of the screening equipment.

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a low-carbon ferrochrome product grading and screening machine, comprising:

[0028] The material storage assembly 100 includes a support 101, a frame 102 fixedly installed in the middle of the support 101, and a collection box 103 installed in the middle of the frame 102.

[0029] The screening assembly 200 includes a support member 201 fixedly installed on the upper end of the frame 102, a connector 202 threadedly connected to the upper end of the support member 201, a screening box 203 rotatably installed on the side wall of the connector 202, a screen plate 204 fixedly connected to the inner side of the screening box 203, and a feed frame 205 inserted into the middle position of the end of the screening box 203. The screen plate 204 is adapted to be installed above the collection box 103, and the bottom of the feed frame 205 extends to the upper end of the screen plate 204.

[0030] The support frame 101 serves as the foundation for the entire grading and screening machine, providing a stable mounting platform for other components and ensuring the overall stability of the equipment. The frame 102 is fixedly installed in the middle of the support frame 101, connecting and supporting the screening assembly 200, thus forming an organic whole between the screening assembly 200 and the storage assembly 100. The collection box 103 is installed in the middle of the frame 102 to collect the screened low-carbon ferrochrome products. The support member 201 is fixedly installed on the upper end of the frame 102, providing support for the connecting member 202 and ensuring the installation stability of the screening box 203. The connecting member 202 is threadedly connected to the upper end of the support member 201, connecting the support member 201 and the screen. The function of the screening box 203 is to allow the screening box 203 to be rotatably mounted on the side wall of the connector 202. The screening box 203 is the main place for screening operations. The screening box 204 is installed inside the screening box 203 and is fixedly connected to the inside of the screening box 203 and adapted to be installed above the collection box 103. Its function is to classify and screen the low carbon ferrochrome products entering the screening box 203. Materials that meet the size requirements fall into the collection box 103 below through the screen plate 204. The feed frame 205 is inserted into the middle position of the end of the screening box 203 and extends to the upper end of the screen plate 204 at the bottom. It is used to transport the low carbon ferrochrome products to be screened into the screening box 203.

[0031] Specifically, the screening component 200 also includes a guide box 206 fixedly installed on the side wall of the bracket 101, and an insert plate 207 inserted into the feed inlet at the end of the guide box 206. The feed inlet at the end of the guide box 206 is connected to the end of the screening box 203, and the discharge outlet at the lower end of the guide box 206 is connected to the collection box 103.

[0032] The guide box 206 is fixedly installed on the side wall of the bracket 101. Its end inlet is connected to the end of the screening box 203, and its lower outlet is connected to the collection box 103, thus guiding the material from the screening box 203 into the collection box 103. The insert plate 207 is inserted into the end inlet of the guide box 206, and the opening and closing of the inlet of the guide box 206 can be controlled by inserting and removing the insert plate 207, thereby controlling the flow of material.

[0033] Furthermore, the screening assembly 200 also includes a support plate 208 installed inside the screening box 203, and a vibration motor 209 fixedly connected to the side wall of the support plate 208. The support plate 208 is positioned above the sieve plate 204.

[0034] The support plate 208 is installed inside the screening box 203 and above the screen plate 204, providing mounting support for the vibration motor 209. The vibration motor 209 is fixedly connected to the side wall of the support plate 208, and by generating vibration, it causes the material on the screen plate 204 to vibrate continuously, thereby improving screening efficiency and effectiveness.

[0035] Furthermore, the screening assembly 200 also includes a filter 210 installed inside the guide box 206, and a fan 211 installed at the air outlet of the filter 210, with the air inlet pipe of the filter 210 extending to the side wall of the insert plate 207.

[0036] The filter 210 is installed inside the guide box 206, and its air inlet pipe extends to the side wall of the insert plate 207 to filter dust and other impurities generated during the screening process. The fan 211 is installed at the air outlet of the filter 210 to provide power for the filtration process, allowing the dust-laden gas to pass through the filter 210 for purification.

[0037] Preferably, the screening assembly 200 also includes a guide plate 212 installed at the end of the screening box 203, the end of the guide plate 212 being connected to the feed frame 205.

[0038] The guide plate 212 is installed at the end of the screening box 203 and its end is connected to the feed frame 205. It guides the material from the feed frame 205 to the outside, intercepts large particles that exceed the specifications, and reduces the workload of the screening machine.

[0039] It should be noted that the storage assembly 100 also includes a discharge pipe 104 installed on the side wall of the collection box 103, and the discharge pipe 104 is connected to the inside of the collection box 103.

[0040] The discharge pipe 104 is installed on the side wall of the collection box 103 and communicates with the inside of the collection box 103. Its function is to discharge the material collected in the collection box 103.

[0041] Preferably, the storage assembly 100 further includes a tubular screw conveyor 105 adapted to be installed inside the discharge pipe 104, and a motor 106 fixedly connected to the side wall of the support 101, with the output end of the motor 106 being drively connected to the input end of the tubular screw conveyor 105.

[0042] The tubular screw conveyor 105 is adapted to be installed inside the discharge pipe 104. The material is moved within the discharge pipe 104 by the rotation of the screw blades, thereby realizing the material conveying.

[0043] The motor 106 is fixedly connected to the side wall of the bracket 101, and its output end is connected to the input end of the tubular screw conveyor 105 to provide power to the tubular screw conveyor 105 and drive the screw blades to rotate.

[0044] When using,

[0045] Feeding stage: The low-carbon ferrochrome product to be screened enters the screening machine through the feeding frame 205, and the guide plate 212 will smoothly guide the material to the screen plate 204 in the screening box 203.

[0046] Screening stage: The vibration motor 209 installed on the support plate 208 is started. The vibration generated by the motor is transmitted to the screen plate 204, causing the low carbon ferrochrome products on the screen plate 204 to jump and tumble continuously. During this process, fine particles that meet the aperture requirements of the screen plate 204 will pass through the screen plate 204 and fall directly into the collection box 103 below. The larger particles that cannot pass through the screen plate 204 will move towards the end of the screen box 203 with the rotation and vibration of the screen box 203, and finally enter the guide box 206 that is connected to the end of the screen box 203.

[0047] Guiding stage: The guide box 206 plays the role of transitioning and guiding materials. The baffle plate 207 at its inlet can control the flow rate and direction of materials according to actual needs. After the materials are discharged inside the collection box 103, the baffle plate 207 is opened so that the larger particle size materials inside the screening box 203 also enter the collection box 103 after passing through the guide box 206, realizing the initial collection of materials of different particle sizes.

[0048] Dust removal stage: During the screening process, the fan 211 is started, so that the dust-laden gas generated during screening enters the filter 210 through the air inlet pipe of the filter 210; the filter 210 will intercept dust and other impurities, and the purified gas will be discharged from the air outlet of the filter 210, effectively reducing dust pollution during the screening process.

[0049] Discharge stage: The collection bin 103 collects the screened low-carbon ferrochrome products, and the motor 106 drives the tubular screw conveyor 105 to transport the material in the collection bin 103 out through the discharge pipe 104 to complete the entire screening process.

[0050] In summary, the combined use of the storage component 100 and the screening component 200 allows for full movement of the material on the screen plate, avoiding material accumulation and screen hole blockage, thus improving screening efficiency. It can quickly and accurately separate low-carbon ferrochrome products of different particle sizes, facilitating the adjustment and maintenance of the screening box. The insert plate can control the opening and closing of the feed inlet of the guide box and the material flow rate, enhancing the flexibility of equipment operation and ensuring the continuity and stability of the entire screening process.
