Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an electromagnetic vibration feeding device. Background Technology

[0002] In the process of processing and producing ferrosilicon inoculants, electromagnetic vibration feeding equipment is used to connect and stably supply materials between the silo and the belt conveyor. The quantitative feeding of the electromagnetic vibration feeding equipment prevents material blockage and excessive wear of the equipment.

[0003] Existing vibrating troughs are mostly open or semi-open designs. During the vibrating conveying process, materials (especially powders and lightweight particles) generate a lot of dust, which deteriorates the surrounding production environment. In addition, the discharge structure of existing devices is mostly rigidly fixed. Currently, the distance between the discharge hopper and the belt conveyor is too large. During the free fall of materials, they are affected by air resistance and vibration inertia, and are horizontally offset and scattered around the belt, which increases the loss of raw materials and the cleaning burden on personnel. Summary of the Invention

[0004] This utility model provides an electromagnetic vibration feeding device. The upper dust collection cover covers and seals the vibration trough. The negative pressure dust collection module performs negative pressure suction and collection of dust generated by the vibration feeding in the vibration trough, avoiding the generation of a large amount of flying dust during vibration feeding, improving the surrounding production environment, and recovering more than 95% of the scattered dust. The discharge pipe pulls the upper corrugated telescopic tube to extend and retract, adjusting the discharge height and the spacing of the belt conveyor device. This prevents the raw material from falling outside the belt conveyor device when the distance between the lower discharge hopper and the belt conveyor device is too large.

[0005] This utility model provides an electromagnetic vibration feeding device, specifically including an electromagnetic vibrator, a vibration trough, and a discharge pipe. The top armature of the electromagnetic vibrator is fixedly connected to the vibration trough, and the discharge pipe is provided below the tail end of the vibration trough. A lower base is fixedly connected to the bottom of the electromagnetic vibrator. Spring plates are bolted to the top of the lower base at both the front and back. The spring plates are made of 5mm thick 60Si2Mn alloy spring steel. Lower buffer pads are fixedly connected to the bottom of the lower base at both the front and back. The lower buffer pads are made of nitrile rubber and have a compression of 10-20mm.

[0006] Furthermore, the upper end of the spring plate is fixedly connected to the vibration groove. The spring plate is located on the front and rear sides of the electromagnetic vibrator. The electromagnetic vibrator coil power is 500W, the working air gap is 1.5mm, the vibration frequency is 50Hz, and the amplitude is adjustable from 0-5mm. The current of the electromagnetic vibrator is adjusted by a thyristor power supply to control the material conveying amount. The iron core of the electromagnetic vibrator is fixed to the middle of the lower base by bolts, and the armature is welded to the corresponding position at the bottom of the vibration groove. The working air gap is 1.5mm±0.1mm.

[0007] Furthermore, the top of the first end of the vibration trough is connected and fixed to an upper feed hopper, the upper part of the vibration trough is covered and fixedly connected to an upper dust collection cover, the upper dust collection cover and the connecting hose are connected and fixedly connected, the tail end of the vibration trough is connected and fixed to a lower discharge hopper, the tail end of the connecting hose is connected to the dust collection bag of the negative pressure dust collection module, the negative pressure dust collection module is composed of a negative pressure pump and a high temperature resistant dust collection bag, and the upper dust collection cover and the vibration trough are sealed by a silicone sealing ring.

[0008] Furthermore, the negative pressure dust collection module is fixedly connected to the lower base. The negative pressure dust collection module is connected to the inside of the vibration groove through a connecting hose and an upper dust collection cover. The negative pressure dust collection module is connected to the vibration groove through a connecting hose to perform negative pressure suction and collection of dust generated by vibration feeding.

[0009] Furthermore, the upper part of the discharge pipe is connected and fixed with an upper corrugated telescopic pipe, which is a flexible and telescopic corrugated pipe structure. A side connecting slide is fixedly connected to the outside of the discharge pipe. Both sides of the side connecting slide are slidably connected with inner sliders. The inner sliders are threadedly connected to the middle threaded rod. The middle threaded rod has a specification of M12×1.5 and an adjustment range of 0-200mm. The upper part of the inner slider is rotatably connected to the upper scissor bracket.

[0010] Furthermore, the upper end of the upper scissor bracket is slidably connected to the upper slide groove seat, and the upper end of the upper slide groove seat is fixedly connected to the vibration groove. The threads at both ends of the central threaded rod rotate in opposite directions. When rotated manually, the inner sliders on both sides are driven to move closer or further apart, thereby folding or unfolding the upper scissor bracket and adjusting the height and horizontal position of the discharge pipe. The folding angle of the upper scissor bracket is 30°-90°, and the maximum load is 50kg, so that the outlet height of the discharge pipe can be steplessly adjusted within the range of 300-500mm.

[0011] Furthermore, the upper end of the upper corrugated telescopic tube is connected and fixed to the lower discharge hopper, the tail end of the vibrating trough is connected to the upper corrugated telescopic tube through the lower discharge hopper, the discharge pipe is connected to the lower discharge hopper through the upper corrugated telescopic tube, and the discharge pipe is flexibly connected through the upper corrugated telescopic tube to adjust the distance between the discharge pipe and the belt conveyor.

[0012] This utility model provides an electromagnetic vibration feeding device, which has the following beneficial effects:

[0013] The upper dust collection cover seals the vibrating trough, and the negative pressure dust collection module uses negative pressure to suck up and collect the dust generated by the vibrating feeding of the vibrating trough, avoiding the generation of a large amount of flying dust by the vibrating feeding, improving the surrounding production environment, and can recover more than 95% of scattered dust (such as ferrosilicon powder), reducing raw material waste and improving economic efficiency.

[0014] The discharge pipe pulls the upper corrugated telescopic tube to extend and retract, adjusting the discharge height and the spacing of the belt conveyor. This prevents the material from falling outside the belt conveyor when the distance between the lower discharge hopper and the belt conveyor is too large. The discharge pipe is close to the belt conveyor for discharge, reducing the scattering range of the material and ensuring that the material falls onto the belt. This solves the compatibility problem between the traditional rigid discharge structure and the belt conveyor. Attached Figure Description

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes an electromagnetic vibration feeding device, including an electromagnetic vibrator 1, a vibration groove 2, and a discharge pipe 3. A lower base 101 is fixedly connected to the bottom of the electromagnetic vibrator 1. Spring plates 102 are bolted to the front and rear of the top of the lower base 101. The spring plates 102 are made of 5mm thick 60Si2Mn alloy spring steel. Lower buffer blocks 103 are fixedly connected to the front and rear of the bottom of the lower base 101. The lower buffer blocks 103 are made of nitrile rubber with a compression range of 10-20mm. The upper part of the spring plate 102... The end and the vibration groove 2 are fixedly connected. The spring plate 102 is located on the front and rear sides of the electromagnetic vibrator 1. The electromagnetic vibrator 1 has a coil power of 500W, a working air gap of 1.5mm, a vibration frequency of 50Hz, and an adjustable amplitude of 0-5mm. The material conveying amount is controlled by adjusting the current of the electromagnetic vibrator 1 with a thyristor power supply. The iron core of the electromagnetic vibrator 1 is fixed to the middle of the lower base 101 by bolts. The armature is welded to the corresponding position at the bottom of the vibration groove 2. The working air gap is 1.5mm ± 0.1mm. The top armature of the electromagnetic vibrator 1 and The vibrating trough 2 is fixedly connected, with an upper feed hopper 201 fixedly connected to the top of its first end. An upper dust collection cover 202 is fixedly connected to the upper part of the vibrating trough 2, and the upper dust collection cover 202 is fixedly connected to a connecting hose 203. A lower discharge hopper 204 is fixedly connected to the tail end of the vibrating trough 2. The tail end of the connecting hose 203 is connected to the dust collection bag of the negative pressure dust collection module 205. The negative pressure dust collection module 205 consists of a negative pressure pump and a high-temperature resistant dust collection bag. The upper dust collection cover 202 is sealed to the vibrating trough 2 by a silicone sealing ring. The tail end of the vibrating trough 2... A discharge pipe 3 is provided at the lower end. The upper part of the discharge pipe 3 is connected and fixed to an upper corrugated telescopic pipe 301. The upper corrugated telescopic pipe 301 is a flexible and telescopic corrugated pipe structure. A side connecting slide 302 is fixedly connected to the outside of the discharge pipe 3. The inner slider 303 is slidably connected to both sides of the inner side connecting slide 302. The inner slider 303 is threadedly connected to the middle threaded rod 304. The middle threaded rod 304 has a specification of M12×1.5 and an adjustment range of 0-200mm. The upper part of the inner slider 303 is rotatably connected to the upper scissor bracket 305.

[0031] In this embodiment, the negative pressure dust collection module 205 and the lower base 101 are fixedly connected. The negative pressure dust collection module 205 is connected to the inside of the vibration groove 2 through the connecting hose 203 and the upper dust collection cover 202. The negative pressure dust collection module 205 is connected to the vibration groove 2 through the connecting hose 203 to perform negative pressure suction and collection of dust generated by vibration feeding, so as to avoid a large amount of flying dust generated by vibration feeding, improve the surrounding production environment, and recover more than 95% of scattered dust such as ferrosilicon powder, thereby reducing raw material waste.

[0032] In this embodiment, the upper end of the upper scissor bracket 305 is slidably connected to the upper slide seat 306, and the upper end of the upper slide seat 306 is fixedly connected to the vibration groove 2. The threads at both ends of the central threaded rod 304 have opposite directions. When rotated manually, the inner sliders 303 on both sides are driven to move closer or further apart, thereby folding or unfolding the upper scissor bracket 305 and adjusting the height and horizontal position of the discharge pipe 3. The folding angle of the upper scissor bracket 305 is 30°-90°, and the maximum load is 50kg. This allows the outlet height of the discharge pipe 3 to be steplessly adjusted within the range of 300-500mm, adapting to the feeding height requirements of different models of belt conveyors with a bandwidth of 500-1200mm.

[0033] In this embodiment, the upper end of the upper corrugated telescopic tube 301 is connected and fixed to the lower discharge hopper 204. The tail end of the vibrating groove 2 is connected to the upper corrugated telescopic tube 301 through the lower discharge hopper 204. The discharge pipe 3 is connected to the lower discharge hopper 204 through the upper corrugated telescopic tube 301. The discharge pipe 3 is flexibly connected through the upper corrugated telescopic tube 301. The distance between the discharge pipe 3 and the belt conveyor is adjusted to avoid the situation where the raw material falls outside the belt conveyor when the distance between the lower discharge hopper 204 and the belt conveyor is too large.

[0034] In this second embodiment, based on the first embodiment, the negative pressure dust collection module 205 is not set up. The connecting hose 203 directly shares a negative pressure dust collection module 205 with the belt conveyor equipment, etc. The centralized use of a single negative pressure dust collection module 205 reduces the setting cost of a single negative pressure dust collection module 205 and also reduces the burden of cleaning the dust inside each negative pressure dust collection module 205 one by one.

[0035] The working principle of this embodiment is as follows: The outlet of the hopper is connected to the upper feed hopper 201. The raw material enters the vibrating trough 2 through the upper feed hopper 201. The electromagnetic vibrator 1 is started, driving the vibrating trough 2 to vibrate. The vibrating trough 2 vibrates to perform a uniform feeding operation. The raw material flows out through the lower discharge hopper 204 towards the upper corrugated telescopic pipe 301 and the discharge pipe 3. The discharge pipe 3 discharges the material onto the conveyor belt. The upper dust collection cover 202 covers and seals the vibrating trough 2. The negative pressure dust collection module 205 is connected to the vibrating trough 2 through the connecting hose 203 to perform negative pressure suction and collection of dust generated by the vibrating feeding, avoiding the generation of a large amount of flying dust by the vibrating feeding, and improving the surrounding production environment. The dust concentration within 1m around the equipment is reduced from 48mg / m³ in traditional equipment. 3 Reduced to 3.2 mg / m³ 3 The replacement cycle of respiratory protective equipment for operators is extended by 3 times, and more than 95% of scattered dust such as ferrosilicon powder can be recovered, reducing raw material waste and improving economic efficiency.

[0036] Manually rotating the threaded rod 304 causes the inner sliders 303 on both sides of the threaded rod 304 to move in opposite directions. This changes the distance between the upper scissor bracket 305 supporting the side connecting slide 302 and the upper slide seat 306. The side connecting slide 302 drives the discharge pipe 3 to move synchronously. The discharge pipe 3 pulls the upper corrugated telescopic tube 301 to extend and retract, adjusting the discharge height. The 30°-90° folding angle adjustment of the upper scissor bracket 305, combined with the 200mm extension of the upper corrugated telescopic tube 301, allows the outlet height of the discharge pipe 3 to be steplessly adjusted within the range of 300-500mm, adapting to the feeding height of different belt conveyor models with a belt width of 500-1200mm. The requirement is to adjust the distance between the discharge pipe 3 and the belt conveyor to prevent raw materials from falling outside the belt conveyor when the distance between the lower discharge hopper 204 and the belt conveyor is too large. The discharge pipe 3 is closer to the belt conveyor for discharge, which reduces the scattering range of the raw materials and ensures that the raw materials fall onto the belt. When the distance between the outlet of the discharge pipe 3 and the belt surface is reduced from 300mm in the traditional equipment to 50mm, the horizontal offset of the free fall of the material is reduced from ±150mm to ±30mm, and the scattering rate is reduced from 8% to below 0.5%, which reduces the cleaning burden on personnel and solves the compatibility problem between the traditional rigid discharge structure and the belt conveyor.
