Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of vibrating feeder technology, and more specifically, to a vibrating feeder for a raw material mill with a sealing function. Background Technology

[0002] A vibrating feeder is a mechanical device that uses controllable vibration excitation force to drive the periodic movement of a trough, thereby enabling the continuous, quantitative, and directional conveying of materials from storage silos to processing equipment. It is used in industries such as mining, metallurgy, chemicals, building materials, and food.

[0003] In the cement production process, the vibrating feeder of the raw material mill is located between the scraper chamber and the slag discharge bucket of the raw material mill. Therefore, during the operation of the vibrating feeder, the material may be located in the lower part of the vibrating feeder. As a result, the material is thin in the middle and upper parts, which will cause some air leakage in the upper part. This will increase the wind resistance of the process and affect the air direction in the raw material mill, thereby reducing the processing efficiency and wasting energy.

[0004] Therefore, we need a vibrating feeder to solve the above-mentioned technical problems. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a raw material mill vibrating feeder with a sealing function, which solves the technical problem in the prior art that the vibrating feeder of the raw material mill in the cement production process is prone to air leakage, affecting the efficiency of other processes and wasting energy.

[0006] According to one aspect, at least one embodiment of this disclosure provides a vibratory feeder for a raw material mill with a sealing function, including a machine body and an air supply assembly and a vibratory feeder assembly disposed on the machine body, wherein the air supply assembly is located at the bottom of the vibratory feeder assembly, and the vibratory feeder assembly includes,

[0007] A vibrating frame, which is reciprocatingly mounted on the machine body, has a feed inlet and a discharge outlet, which are located at opposite ends of the vibrating frame.

[0008] A sealing plate is slidably mounted vertically on the vibrating frame. The sealing plate is slidably located at the feed inlet and is used to open or close the feed inlet.

[0009] As a further technical solution, the vibrating frame has a first guide groove, which is vertically arranged; the sealing plate has a sliding part, which is slidably disposed within the first guide groove; the sliding part has a threaded groove, which is vertically arranged; and the vibrating feed assembly further includes…

[0010] A drive screw is rotatably mounted on the vibration frame. The drive screw passes through the threaded groove and is threadedly engaged with the threaded groove. The rotation of the drive screw is used to drive the sealing plate to slide in the vertical direction.

[0011] As a further technical solution, there are two sliding parts located on both sides of the sealing plate, two first guide grooves and two drive screws, and the vibrating feeding assembly also includes two drive motors, with the output ends of the two drive motors respectively connected to the two drive screws.

[0012] As a further technical solution, the vibrating frame also has a second guide groove, which is located on both sides of the top of the vibrating frame. The vibrating feeding assembly also includes a baffle plate, which is slidably disposed in the second guide groove and is used to baffle the top of the vibrating frame.

[0013] As a further technical solution, the vibratory feeding assembly also includes elastic elements, at least two of which are connected at one end to the vibratory frame and the other end to the machine body.

[0014] A vibration motor is mounted on the vibration frame and is used to provide force for the reciprocating motion of the vibration frame.

[0015] As a further technical solution, the air supply assembly includes an air supply pipe, which is disposed at the bottom of the vibrating frame, and the air supply fan is disposed on the air supply pipe, with the air supply fan located at the inlet end of the air supply pipe.

[0016] As a further technical solution, the vibrating feeder assembly also includes a screen body, which is disposed on the vibrating frame and moves with the vibrating frame. The screen body is located at the bottom of the vibrating frame and has several evenly distributed through holes on it, which connect the air supply pipe and the vibrating frame.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, when material needs to be conveyed, the control sealing plate slides upward to open the feed inlet, allowing material to enter the vibrating frame from the storage bin. The vibrating frame, under the action of a corresponding drive device, reciprocates, conveying the material from the feed inlet to the discharge outlet. When feeding is not required or the feed rate needs to be controlled, the control sealing plate slides downward to close the feed inlet, preventing airflow within the vibrating feeder from affecting the operation of the preceding parts.

[0019] By installing a sliding sealing plate at the feed inlet, the air leakage caused by the thin material in the upper part of the traditional vibrating feeder is effectively avoided, which affects the material in the scraper cavity. This reduces wind resistance, ensures the stability of the airflow direction inside the raw material mill, improves processing efficiency, and reduces energy waste. Attached Figure Description

[0030] like Figures 1-2 The diagram illustrates a vibratory feeder for a raw material mill with a sealing function according to an embodiment of this disclosure. It includes a machine body 1, an air supply assembly 2, and a vibratory feeder assembly 3 mounted on the machine body 1. The air supply assembly 2 is located at the bottom of the vibratory feeder assembly 3. The vibratory feeder assembly 3 includes…

[0031] A vibrating frame 301 is reciprocatingly mounted on the machine body 1. The vibrating frame 301 has a feed inlet 311 and a discharge outlet 312, which are located at opposite ends of the vibrating frame 301.

[0032] A sealing plate 302 is slidably disposed on the vibrating frame 301 along a vertical direction. The sealing plate 302 is slidably located at the feed inlet 311. The sealing plate 302 is slidably used to open or close the feed inlet 311.

[0033] In this embodiment, when material needs to be conveyed, the control sealing plate 302 slides upward to open the feed inlet 311, and the material enters the vibrating frame 301 from the storage bin through the feed inlet 311. The vibrating frame 301 reciprocates under the action of the corresponding drive device, conveying the material from the feed inlet 311 to the discharge outlet 312. When feeding is not required or the feed rate needs to be controlled, the control sealing plate 302 slides downward to close the feed inlet 311, preventing the airflow inside the vibrating feeder from affecting the operation of the preceding part.

[0034] By setting a sliding sealing plate 302 at the feed inlet 311, the air leakage caused by the thin material in the upper part of the traditional vibrating feeder is effectively avoided from affecting the material in the scraper cavity, reducing wind resistance, ensuring the stability of the air direction in the raw material mill, improving processing efficiency, and reducing energy waste.

[0035] Furthermore, the vibrating frame 301 has a first guide groove 313, which is vertically arranged. The sealing plate 302 has a sliding part 321, which is slidably disposed within the first guide groove 313. The sliding part 321 has a threaded groove 322, which is vertically arranged. The vibrating feed assembly 3 also includes…

[0036] A drive screw 303 is rotatably mounted on the vibration frame 301. The drive screw 303 passes through the threaded groove 322 and is threadedly engaged with the threaded groove 322. The rotation of the drive screw 303 is used to drive the sealing plate 302 to slide in the vertical direction.

[0037] In this embodiment, when the drive screw 303 rotates, it engages with the threaded groove 322 on the sliding part 321. Furthermore, the sliding part 321, guided by the first guide groove 313, can only move vertically. Therefore, the rotation of the drive screw 303 is converted into the vertical sliding of the sealing plate 302, thus opening or closing the feed inlet 311 and adjusting its opening degree. Through the threaded engagement of the drive screw 303 and the threaded groove 322, the vertical position of the sealing plate 302 can be precisely controlled, thereby achieving precise adjustment of the opening degree of the feed inlet 311 and meeting the precise requirements of different production processes for the feed quantity. The engagement of the first guide groove 313 and the sliding part 321 provides a stable guide for the sliding of the sealing plate 302, ensuring the stability of the sealing plate 302 during the sliding process, and thus ensuring the reliability of the seal of the feed inlet 311.

[0038] Furthermore, there are two sliding parts 321, which are located on both sides of the sealing plate 302. There are two first guide grooves 313 and two drive screws 303. The vibrating feed assembly 3 also includes two drive motors 304, and the output ends of the two drive motors 304 are respectively connected to the two drive screws 303.

[0039] In this embodiment, two drive motors 304 start simultaneously, each driving a corresponding drive screw 303 to rotate. Since the two drive screws 303 are threadedly engaged with the threaded grooves 322 on the sliding portions 321 on both sides of the sealing plate 302, and under the guidance of the first guide groove 313, both sides of the sealing plate 302 rise or fall synchronously, achieving smooth opening or closing of the feed inlet 311 and precise adjustment of its opening degree. The arrangement of two drive motors 304 enhances the control precision of the sealing plate 302, enabling more accurate adjustment of the opening degree of the feed inlet 311, meeting the needs of large-scale, high-precision production.

[0040] Furthermore, the vibrating frame 301 also has a second guide groove 314, which is located on both sides of the top of the vibrating frame 301. The vibrating feeding assembly 3 also includes a baffle plate 305, which is slidably disposed in the second guide groove 314 and is used to baffle the top of the vibrating frame 301.

[0041] In this embodiment, when it is necessary to cover the top of the vibrating frame 301, the cover plate 305 is pushed manually or automatically, causing it to slide within the second guide groove 314 until it completely covers the top of the vibrating frame 301. When further operation is required, the cover plate 305 is slid in the opposite direction to remove it from the top of the vibrating frame 301. The cover plate 305 effectively prevents dust and impurities from entering the vibrating frame 301 and contaminating the materials, while also preventing materials from splashing out due to vibration, thus improving the production environment and ensuring the purity of the materials.

[0042] Furthermore, the vibrating feed assembly 3 also includes an elastic element 306, of which there are at least two. One end of the elastic element 306 is connected to the vibrating frame 301, and the other end of the elastic element 306 is connected to the machine body 1. The vibrating motor 307 is mounted on the vibrating frame 301 and is used to provide force for the reciprocating motion of the vibrating frame 301.

[0043] In this embodiment, after the vibratory motor 307 is energized, the eccentric block inside it rotates, generating centrifugal force, causing the vibratory frame 301 to reciprocate. During vibration, the elastic element 306 acts as a buffer, reducing the impact of vibration on the machine body 1 and the vibratory frame 301; furthermore, after the vibratory motor 307 stops working, the elastic element 306 returns the vibratory frame 301 to its initial position, preparing it for the next vibration. The cooperation between the elastic element 306 and the vibratory motor 307 ensures that the vibratory frame 301 can reciprocate stably, improving the efficiency and stability of material conveying and ensuring that the material can be uniformly and continuously conveyed from the feed inlet 311 to the discharge outlet 312.

[0044] Furthermore, the air supply assembly 2 includes an air supply pipe 201, which is disposed at the bottom of the vibration frame 301, and a blower 202 is disposed on the air supply pipe 201, with the blower 202 located at the inlet end of the air supply pipe 201.

[0045] In this embodiment, after the blower 202 is started, air is sent into the bottom of the vibrating frame 301 through the air supply pipe 201. The supplied air flows upward, replenishing the air leakage in the middle and upper parts caused by the thin material, balancing the air pressure in the raw material mill, improving the air direction in the raw material mill, reducing air resistance, and ensuring the smooth progress of material conveying and processing.

[0046] Furthermore, the vibrating feed assembly 3 also includes a screen body 308, which is disposed on the vibrating frame 301 and moves with the vibrating frame 301. The screen body 308 is located at the bottom of the vibrating frame 301 and has a plurality of evenly distributed through holes 381 on it. The through holes 381 connect the air supply pipe 201 and the vibrating frame 301.

[0047] In this embodiment, the material moves on the vibrating frame 301 as it vibrates. The blower 202 sends air into the air supply pipe 201, and the air is blown upward through the through holes 381 of the screen body 308. On the one hand, smaller particles of material continue to be conveyed through the screen body 308, while larger particles or impurities are intercepted. On the other hand, the blown airflow keeps the material in a fluidized state, assisting in the conveying of the material on the vibrating frame 301, while improving the airflow conditions inside the raw material mill.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
