Description

TECHNICAL FIELD

[0001] The utility model relates to a material storage device technical field, specifically to a kind of powdery raw material storage device. BACKGROUND

[0002] In industrial production, the storage and handling of powdery raw materials are crucial links. Traditional storage devices usually rely on gravity to discharge materials from the discharge port, but such devices often face a major problem in practical application: in a humid environment, moisture in the air is absorbed by the powder, forming liquid bridges between particles, increasing adhesion. When the powder is left for a long time, the contact pressure between particles gradually increases, making the friction and adhesion force stronger, eventually forming a relatively solid hardened body. Powdery raw materials are prone to hardening inside the storage device, especially near the discharge port, causing the discharge port to clog and affecting normal material flow. This hardening phenomenon not only reduces production efficiency, but also can cause equipment failure and increase maintenance costs.

[0003] To this end, the present application proposes a powdery raw material storage device to solve the above technical problems. SUMMARY

[0004] The main purpose of the utility model is to solve the above-mentioned shortcomings, and to provide a powdery raw material storage device to avoid clogging of the discharge port of the storage device by hardened powdery materials.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A powdery raw material storage device, comprising a hopper and a cover plate arranged on the top of the hopper, further comprising: a discharge cylinder fixedly connected to the bottom opening of the hopper; a stirring rod assembly rotatably arranged at the top of the inner cavity of the discharge cylinder for stirring and breaking up the hardened powdery raw materials; a support fixedly arranged on the outer wall of the discharge cylinder; a reduction motor fixedly arranged on the support and transmissionally connected to the rotating shaft of the stirring rod assembly; a control baffle rotatably arranged at the bottom of the inner cavity of the discharge cylinder; and an adjusting member arranged on the outer wall of the discharge cylinder for adjusting and locking the inclination angle of the control baffle.

[0007] Further, the stirring rod assembly comprises a mounting shaft rotatably arranged at the top of the inner cavity of the discharge cylinder and a plurality of stirring rods arranged around the mounting shaft.

[0008] Further, the adjusting member comprises a drive worm gear fixedly arranged at one end of the rotating shaft of the stirring rod assembly extending out of the discharge cylinder, a worm rotatably arranged on the outer wall of the discharge cylinder and meshing with the drive worm gear, and a hand wheel fixedly arranged at one end of the rotating shaft of the worm.

[0009] Furthermore, baffles are fixedly installed on both sides of the inner cavity of the discharge cylinder. The two baffles are located on both sides of the rotating shaft of the material control baffle. When the material control baffle is in a horizontal state, one of the baffles abuts against the top surface of the material control baffle, and the other baffle abuts against the bottom surface of the material control baffle.

[0010] Furthermore, a pneumatic hammer is fixedly installed at the bottom of the outer wall of the hopper, and the pneumatic hammer is connected to a high-pressure air source.

[0011] Furthermore, a hinged door is provided on the cover plate, an observation port is provided on the cover plate, and a cover is provided on the top of the observation port.

[0012] The beneficial effects of this utility model are reflected in:

[0013] This invention features a discharge cylinder at the bottom of the hopper, a stirring rod assembly inside the discharge cylinder, and a geared motor to drive the stirring assembly to rotate. When the powdered raw material in the discharge cylinder clumps, the geared motor is activated, driving the stirring rod assembly to rotate. The stirring rod assembly disperses most of the clumped powdered raw material in the discharge cylinder, allowing it to fall smoothly from the control baffle. The discharge speed of the powder can be adjusted by adjusting the tilt angle of the control baffle. In addition, during the rotation of the control baffle while adjusting the tilt angle, it also agitates the nearby clumped powdered raw material, dispersing the clumped powder and allowing it to fall smoothly.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-5 As shown, this utility model provides a powdered raw material storage device, including a hopper 1 and a cover plate 2 disposed on its top, and further including: a discharge cylinder 3, which is fixedly and sealed to the bottom opening of the hopper 1; a stirring rod assembly 4, which is rotatably disposed at the top of the inner cavity of the discharge cylinder 3 for stirring and breaking up the clumped powdered raw material, a support 5 is fixedly disposed on the outer wall of the discharge cylinder 3, and a reduction motor 6, which is driven by the rotating shaft of the stirring rod assembly 4, is fixedly disposed on the support 5; a material control baffle 7, which is rotatably disposed at the bottom of the inner cavity of the discharge cylinder 3; and an adjusting component 8, which is disposed on the outer wall of the discharge cylinder 3 for adjusting and locking the tilt angle of the material control baffle 7.

[0023] In operation, the powdered raw material in hopper 1 enters the discharge cylinder 3. Due to the obstruction of the control baffle 7, it cannot fall further and is thus stored. At this time, the discharge cylinder 3 can be considered the discharge port of the discharge device. When the powdered raw material in the discharge cylinder 3 clumps, the reduction motor 6 is activated, driving the stirring rod assembly 4 to rotate. The stirring rod assembly 4 disperses most of the clumped powdered raw material in the discharge cylinder 3, allowing it to fall smoothly from the control baffle 7. The tilt angle of the control baffle 7 is adjusted by the adjusting component 8. When the control baffle 7 is horizontal, it completely seals the bottom of the inner cavity of the discharge cylinder 3, preventing the powdered raw material from falling due to the obstruction of the control baffle 7. When the control baffle 7 is perpendicular to the horizontal plane, the obstruction effect on the powdered raw material is minimal, and the falling speed of the powder is fastest. By controlling the horizontal tilt angle of the control baffle 7, the discharge speed of the powder can be adjusted. In addition, during the rotation of the control baffle 7 to adjust the tilt angle, it will also have a certain stirring effect on the nearby caking powdery raw materials, which will disperse the caking powder and allow it to fall smoothly.

[0024] In an embodiment, the stirring rod assembly 4 comprises a mounting shaft 41 arranged at the top of the inner cavity of the discharging barrel 3 and a plurality of stirring rods 42 arranged around the mounting shaft 41.

[0025] In this way, the mounting shaft 41 is driven to rotate by the speed reducer motor 6 together with the stirring rods 42, and the stirring rods 42 crush and scatter the agglomerated powdery raw materials around them during rotation, thereby avoiding blockage.

[0026] In an embodiment, the adjusting member 8 comprises a drive worm gear 81 fixedly arranged at the end of the rotating shaft of the stirring rod assembly 4 extending out of the discharging barrel 3, a worm 82 rotatably arranged on the outer wall of the discharging barrel 3 and engaged with the drive worm gear 81, and a hand wheel 83 fixedly arranged at the end of the rotating shaft of the worm 82.

[0027] In this way, the worm 82 is driven to rotate by rotating the hand wheel 83, and the drive worm gear 81 is driven to rotate together with the rotating shaft of the material control baffle 7, thereby driving the material control baffle 7 to rotate and adjusting the inclination angle of the material control baffle 7. Since the transmission between the drive worm gear 81 and the worm 82 has a mechanical self-locking feature, the inclination angle of the material control baffle 7 is locked after adjustment.

[0028] In an embodiment, two blocking strips 9 are fixedly arranged at both sides of the inner cavity of the discharging barrel 3, and the two blocking strips 9 are respectively located at both sides of the rotating shaft of the material control baffle 7. When the material control baffle 7 is in a horizontal state, one of the blocking strips 9 abuts against the top surface of the material control baffle 7, and the other blocking strip 9 abuts against the bottom surface of the material control baffle 7.

[0029] In this way, when the material control baffle 7 abuts against the two blocking strips 9, the gap between the material control baffle 7 and the inner wall of the discharging barrel 3 is small, thereby ensuring the blocking effect of the material control baffle 7 on the powdery raw materials.

[0030] In an embodiment, a pneumatic hammer 10 is fixedly arranged at the bottom of the outer wall of the hopper 1, and the pneumatic hammer 10 is connected to a high-pressure gas source.

[0031] In this way, the outer wall of the hopper 1 is hammered by controlling the pneumatic hammer 10, and the vibration is transmitted to the agglomerated powdery raw materials in the hopper 1 and scattered, thereby further reducing the possibility of blockage caused by the agglomerated powdery raw materials.

[0032] In an embodiment, a flip door 11 is hingedly arranged on the cover plate 2, an observation hole 12 is formed in the cover plate 2, and a cover 13 is arranged on the top of the observation hole 12.

[0033] In this way, after the turnover door 11 is turned over, the powder raw material can be poured into the hopper 1 through the turnover door 11; the powder raw material storage condition in the hopper 1 can be observed through the observation hole 12 by opening the cover 13, and after the observation is completed, the cover 13 is closed again to block the observation hole 12, so that the moisture in the air cannot enter the inner cavity of the hopper 1 through the observation hole 12, and the powder raw material in the hopper 1 is not damp and hardened.

[0034] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.

[0035] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0036] In addition, "a plurality of" means two or more. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.
