Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, specifically to an anti-jamming eagle-beak type unloader. Background Technology
[0002] A rotary valve is a pneumatic conveying device that can continuously and uniformly transport materials while also isolating the upper and lower air pressures to create an airlock effect. It is suitable for conveying powdery and small granular materials and generally consists of a rotor impeller with several blades, bearings, a housing, a sealing device, a reducer, and a motor. During operation, material in the upper hopper falls under its own weight, filling the gaps between the rotor impellers. Then, as the rotor impellers rotate, the material is continuously and quantitatively discharged from the lower part. However, blockage often occurs between the rotor impeller end and the housing sealing device due to material accumulation, causing the motor to overheat and trip, thus affecting the continuity of material conveying.
[0003] Chinese utility model patent publication number "CN205076506U" discloses a rotary valve with an anti-jamming rotor impeller. The rotary valve includes a rotary valve housing with an inlet at the top and an outlet at the bottom. A sealing ring is provided on the inner wall, and a rotor impeller with six blades is located at the center. The impeller end is beveled, which reduces the contact area between the impeller and the sealing ring between the impeller and the rotary valve housing, lowering the probability of jamming and enabling continuous operation of the rotary valve.
[0004] However, the above-mentioned unloader still has the following drawbacks:
[0005] First, when the material enters between the blades of the rotor impeller, it will impact and rub against the blade tips. The structure at the blade tips is prone to wear, causing gaps in the rotor impeller and poor material discharge stability.
[0006] Second, the feed inlet and outlet are symmetrical straight-through type. When there is a rush or a large amount of material being discharged, the material flow directly impacts the middle of the rotor impeller blades, which can easily damage the drive shaft and support bearings.
[0007] Third, the material flow usually accumulates in the middle of the gap between the blades, and the middle of the material pile is significantly higher than the sides, so the unloading capacity of the rotor impeller is not fully utilized.
[0008] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content
[0009] The purpose of this invention is to provide an anti-jamming eagle-beak type unloader that does not cause material to get stuck during unloading, has higher structural stability, and stronger unloading capacity, so as to solve the above-mentioned problems existing in the prior art.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is: an anti-jamming eagle beak type unloader, including an unloader housing, an impeller assembly for unloading material passing through the middle of the housing, and a drive assembly for driving the impeller to rotate. The housing includes an inlet, an unloading chamber, and an outlet. An anti-jamming eagle beak is provided on the inner wall of the inlet in the direction of impeller rotation.
[0011] By adopting the above technical solution: when the impeller assembly rotates in the unloading chamber, the end of the impeller assembly first contacts the bottom of the beak. During unloading, the material flow will first impact the anti-jamming distribution beak. Since the anti-jamming distribution beak is set with a certain tilt angle, the material flow will bounce up a distance before falling into the unloading chamber. The material will not get stuck in the gap between the shell and the impeller assembly, which can effectively reduce the risk of material jamming in the unloader.
[0012] The aforementioned anti-jamming eagle beak type unloader can be further configured as follows: the anti-jamming eagle beak includes a first anti-jamming material distribution component and a second anti-jamming material distribution component stacked with the first anti-jamming material distribution component.
[0013] By adopting the above technical solution: when the material flow impacts the middle of the anti-jamming material distribution eagle beak, the first anti-jamming material distribution component and the second anti-jamming material distribution component can separate the material flow into two parts, and the two parts flow into the two sides of the discharge chamber respectively. When the material on both sides accumulates, it will slide to the middle, and the discharge chamber can discharge a higher amount of material at one time.
[0014] The aforementioned anti-jamming eagle beak type unloader can be further configured as follows: the first anti-jamming material distribution component includes a first material blocking slope and a first material distribution slope inclined to the first material blocking slope; the second anti-jamming material distribution component includes a second material distribution slope inclined to the first material distribution slope and a second material blocking slope inclined to the second material distribution slope.
[0015] By adopting the above technical solution, the first and second retaining slopes effectively block the material, preventing it from directly impacting the inner wall of the feed inlet and the impeller assembly, thus providing buffering and guidance. When the material enters the unloader, the first and second retaining slopes ensure that the material is evenly distributed at the inlet of the unloader, preventing material accumulation and reducing the possibility of blockage. Furthermore, the inclined arrangement of the first distribution slope and the first retaining slope, and the inclined arrangement of the second distribution slope and the second retaining slope, further disperses and guides the material, allowing it to slide smoothly along the distribution slopes under gravity, achieving the material distribution function.
[0016] The aforementioned anti-jamming eagle beak type unloader can be further configured as follows: the impeller assembly includes a rotating shaft, a rotor impeller sleeved on the rotating shaft, and several blades spaced apart on the outer periphery of the rotor impeller. The blades form a material trough for rotating and transporting materials. The end of the blade away from the rotating shaft contacts the inner wall of the unloading chamber. The drive assembly drives the rotating shaft to rotate, thereby driving the impeller to rotate.
[0017] By adopting the above technical solution, the impeller assembly effectively improves the unloading efficiency and reliability of the unloader. When rotating, the impeller assembly ensures that the material is evenly distributed within the unloading chamber under centrifugal force and discharged from the outlet through the material chute. Simultaneously, the contact between the blades and the inner wall of the unloading chamber enhances the unloading device's anti-jamming performance, ensuring smooth material conveying. This makes it suitable for materials with various properties, especially those with poor flowability or prone to agglomeration, thus improving the unloader's applicability.
[0018] The aforementioned anti-jamming eagle-beak type unloader can be further configured as follows: a first mounting block is provided on the outer wall of the housing at the connection between the inlet and the unloading chamber; a second mounting block is provided on the outer wall of the housing at the connection between the unloading chamber and the outlet, which is vertically arranged with the first mounting block; the drive assembly includes a vertical mounting plate with both ends riveted to the first mounting block and the second mounting block respectively; an oblique reinforcing plate is riveted to one side of the vertical mounting plate relative to the second mounting block; a transverse mounting plate is riveted to the upper end face of the oblique reinforcing plate; and a motor mounting bracket for mounting a reduction motor is provided at the upper end of the transverse mounting plate; the reduction motor is synchronously connected to the rotating shaft.
[0019] By adopting the above technical solution: the first mounting block and the second mounting block provide a stable connection position for the drive assembly. The two ends of the vertical mounting plate are riveted to the first mounting block and the second mounting block. The inclined reinforcing plate at the bottom of the vertical mounting plate enhances the stability of the overall structure, enabling the drive structure to be more stably supported on the outer periphery of the housing. The geared motor is installed in the motor mounting bracket at the upper end of the horizontal mounting plate and is synchronously connected with the rotating shaft to provide stable power to the rotating shaft.
[0020] The aforementioned anti-jamming eagle beak type unloader can be further configured as follows: the rotating shaft is provided with a first synchronous end, the geared motor is provided with a second synchronous end, and the first synchronous end and the second synchronous end are connected by a synchronous belt to enable the geared motor to drive the rotating shaft to rotate.
[0021] By adopting the above technical solution, synchronous belt drive can ensure that the rotating shaft and the geared motor achieve precise synchronous rotation, enabling power transmission. At the same time, the synchronous belt connection has good flexibility and buffering effect, which can reduce vibration and noise during equipment operation and protect the equipment from excessive impact.
[0022] The aforementioned anti-jamming eagle beak type unloader can be further configured as follows: the motor mounting bracket includes a motor base and a fixed seat set on the motor base. The fixed seat is provided with several obliquely arranged fixed feet, and vertical fixed feet are also provided between the fixed feet. The oblique fixed feet and the vertical fixed feet form a triangular fixation.
[0023] By adopting the above technical solution, the inclined fixed foot and the vertical fixed foot form a triangular fixing structure, making the geared motor more stable during operation, reducing vibration and displacement, ensuring stable power transmission, and improving the efficiency and accuracy of material unloading.
[0024] The beneficial effects of this invention are as follows: By installing an anti-jamming distribution nozzle on the inner wall of the feed inlet, the material flow can be divided and blocked, preventing material from getting stuck in the unloader. Furthermore, the anti-jamming distribution nozzle includes a first anti-jamming distribution component and a second anti-jamming distribution component, avoiding concentrated material accumulation and reducing the possibility of blockage. It also prevents the material flow from directly impacting the blades, improving the stability of the impeller assembly. Additionally, material begins to accumulate on both sides of the material trough, allowing for a larger single-pass material load and higher unloading efficiency of the unloader.
[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] like Figures 1 to 4 The illustrated anti-jamming feeder includes a feeder housing 1, an impeller assembly 2 inserted through the middle of the housing 1 for unloading, and a drive assembly 3 for driving the impeller to rotate. The housing 1 includes an inlet 11, a discharge chamber 12, and an outlet 13. An anti-jamming feeder nozzle 4 is provided on the inner wall of the inlet 11 in the direction of impeller rotation. When the impeller assembly 2 rotates in the discharge chamber 12, the end of the impeller assembly 2 first contacts the bottom of the nozzle. During unloading, the material flow first impacts the anti-jamming feeder nozzle 4. Because the anti-jamming feeder nozzle 4 is set at a certain angle, the material flow will bounce a certain distance before falling into the discharge chamber 12. The material will not get stuck in the gap between the housing 1 and the impeller assembly 2, which can effectively reduce the risk of material jamming in the feeder.
[0033] The anti-jamming material distribution nozzle 4 includes a first anti-jamming material distribution component 41 and a second anti-jamming material distribution component 42 stacked with the first anti-jamming material distribution component 41. When the material flow impacts the middle of the anti-jamming material distribution nozzle 4, the first anti-jamming material distribution component 41 and the second anti-jamming material distribution component 42 can separate the material flow into two parts, which flow into the two sides of the discharge chamber 12 respectively. The material on both sides will slide towards the middle when it accumulates, and the discharge chamber 12 can discharge a higher amount of material at one time.
[0034] The first anti-jamming material distribution component 41 includes a first retaining slope 411 and a first distribution slope 412 inclined to the first retaining slope 411. The second anti-jamming material distribution component 42 includes a second distribution slope 422 inclined to the first distribution slope 412 and a second retaining slope 421 inclined to the second distribution slope 422. The first retaining slope 411 and the second retaining slope 421 can effectively block materials, preventing materials from directly impacting the inner wall of the feed inlet 11 and the impeller assembly 2, thus playing a buffering and guiding role. When materials enter the unloader, the first retaining slope 411 and the second retaining slope 421 can make the materials evenly distributed at the inlet of the unloader, avoiding material accumulation and reducing the possibility of blockage. In addition, the inclined arrangement of the first material distribution slope 412 and the first material blocking slope 411, and the inclined arrangement of the second material distribution slope 422 and the second blocking slope, can further disperse and guide the material, so that the material can slide smoothly along the material distribution slope under the action of gravity, thereby realizing the material distribution function.
[0035] The impeller assembly 2 includes a rotating shaft 21, a rotor impeller 22 sleeved on the rotating shaft 21, and several blades 23 spaced apart on the outer periphery of the rotor impeller 22. The blades 23 form a material trough 24 for rotating and transporting material. The end of the blade 23 away from the rotating shaft 21 contacts the inner wall of the discharge chamber 12. The drive assembly 3 drives the rotating shaft 21 to rotate, which in turn drives the impeller to rotate. The impeller assembly 2 effectively improves the discharge efficiency and reliability of the unloader. When rotating, the impeller assembly 2 enables the material to be evenly distributed within the discharge chamber 12 under centrifugal force and discharged from the outlet 13 through the material trough 24. Simultaneously, the contact between the blades 23 and the inner wall of the discharge chamber 12 enhances the anti-jamming performance of the unloader, ensuring smooth material transport. It is suitable for materials with various characteristics, especially those with poor flowability or prone to agglomeration, thus improving the applicability of the unloader.
[0036] A first mounting block 14 is provided on the outer wall of the housing 1 at the connection between the inlet 11 and the discharge chamber 12. A second mounting block 15 is provided on the outer wall of the housing 1 at the connection between the discharge chamber 12 and the outlet 13, which is vertically arranged with the first mounting block 14. The drive assembly 3 includes a vertical mounting plate 31 with both ends riveted to the first mounting block 14 and the second mounting block 15 respectively. An oblique reinforcing plate 32 is riveted to the side of the vertical mounting plate 31 relative to the second mounting block 15. A transverse mounting plate 33 is riveted to the upper end face of the oblique reinforcing plate 32. A motor mounting bracket 35 for mounting a reduction motor 34 is provided at the upper end of the transverse mounting plate 33. The reduction motor 34 is synchronously connected to the rotating shaft 21. The first mounting block 14 and the second mounting block 15 provide a stable connection position for the drive assembly 3. The two ends of the vertical mounting plate 31 are riveted to the first mounting block 14 and the second mounting block 15. The inclined reinforcing plate 32 at the bottom of the vertical mounting plate enhances the stability of the overall structure, enabling the drive structure to be more stably supported on the outer periphery of the housing 1. The geared motor 34 is installed in the motor mounting bracket 35 at the upper end of the horizontal mounting plate 33 and is synchronously connected with the rotating shaft 21 to provide stable power to the rotating shaft 21.
[0037] The rotating shaft 21 is provided with a first synchronous end 211, and the geared motor 34 is provided with a second synchronous end 341. The first synchronous end 211 and the second synchronous end 341 are connected by a synchronous belt 342, enabling the geared motor 34 to drive the rotating shaft 21 to rotate. The synchronous belt 342 transmission ensures that the rotating shaft 21 and the geared motor 34 achieve precise synchronous rotation, enabling power transmission. At the same time, the synchronous belt 342 connection has good flexibility and buffering effect, which can reduce vibration and noise during equipment operation and protect the equipment from excessive impact.
[0038] The motor mounting bracket 35 includes a motor base 351 and a fixing seat 352 disposed on the motor base 351. The fixing seat 352 has several obliquely arranged fixing feet 353, and vertical fixing feet 354 are also provided between the fixing feet. The oblique fixing feet 353 and the vertical fixing feet 354 form a triangular fixing structure. The triangular fixing structure formed by the oblique fixing feet 353 and the vertical fixing feet 354 makes the geared motor 34 more stable during operation, reduces vibration and displacement, ensures stable power transmission, and improves the efficiency and accuracy of material unloading.
[0039] The beneficial effects of this utility model are as follows: By setting an anti-jamming distribution nozzle 4 on the inner wall of the feed inlet 11, the material flow can be divided and blocked, preventing material from getting stuck in the unloader. In addition, the anti-jamming distribution nozzle 4 includes a first anti-jamming distribution component 41 and a second anti-jamming distribution component 42, which avoids the concentrated accumulation of material, thereby reducing the possibility of blockage. At the same time, it can prevent the material flow from directly impacting the blades 23, improving the stability of the impeller assembly 2, and the material begins to accumulate on both sides of the material trough 24, allowing for a larger amount of material to be carried at one time, and thus increasing the unloading efficiency of the unloader.
[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
