Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of metering bin, specifically to a high purity magnesia metering bin. BACKGROUND

[0002] In the production and processing industry of magnesia, high purity magnesia as an important raw material, the accuracy of its measurement and the controllability of its discharge are of vital importance to ensure product quality, improve production efficiency and control production cost. At present, the existing magnesia metering bin on the market has many problems in the design of the bottom discharge port, which seriously affects the smooth progress of the production process.

[0003] The existing fixed mode of the bottom discharge port of the magnesia metering bin mostly adopts traditional mechanical locking devices, such as bolt fastening, clamp fixing, etc. These fixed modes have obvious disadvantages in actual operation. Taking bolt fastening as an example, when the metering bin needs to be cleaned, maintained or replaced, the operator needs to use tools to loosen and tighten multiple bolts one by one, which not only consumes time and effort, but also easily leads to insecure fixation due to the loosening or loss of the bolts, affecting the normal use of the metering bin. Although the clamp fixing mode simplifies the operation to some extent, the clamp is prone to lose elasticity due to wear and deformation in the long-term use, leading to a decline in the fixing effect and the need for frequent replacement of the clamp, increasing the production cost and maintenance workload.

[0004] In the production process of magnesia, accurate control of the discharge flow is the key link to ensure the stability of product quality. However, the existing magnesia metering bin has many deficiencies in the control of discharge flow. Some metering bins use simple valves to control the discharge flow, but the opening adjustment of the valve is often not accurate enough to achieve stable control of the flow. During the opening of the valve, due to the flow characteristics of magnesia, the flow may become large or small, leading to inaccurate material proportioning in the subsequent production process and affecting the quality and performance of the product.

[0005] To solve the above problems, we propose a high purity magnesia metering bin. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figure 1、 Figure 2 、 Figure 3 、 Figure 4 The utility model provides a technical scheme: a kind of high-purity magnesia measuring bin, including frame body 1, bunker 2, ration control hopper 3, driving device 4 and fixing device 5.

[0026] The frame body 1 is made of high-strength steel material, has good strength and rigidity, and can withstand the gravity of magnesia and the impact force when discharging. The frame body 1 is provided with a plurality of reinforcing ribs inside, further enhancing the stability of the frame. At the same time, the frame body 1 is provided with the bunker 2 on top, and the frame body 1 provides a stable support platform for the bunker 2. The frame body 1 is also provided with a support beam 11 inside, which is used to support and guide the sliding support rod 35 of the ration control hopper 3.

[0027] The bunker 2 is provided with a discharge port at the bottom. The side wall of the bunker 2 is welded with the fixing device 5 near the discharge port for clamping the ration control hopper 3, and the driving device 4 is provided on the side wall of the bunker 2 for driving the ration control hopper 3 to rotate. The same side wall of the bunker 2 is welded with a driving mounting plate 21 and an auxiliary mounting plate 22, which provide fixed positions for the installation of the driving device 4 and the ration control hopper 3 respectively. In addition, the side wall of the bunker 2 is also welded with an auxiliary mounting table 23 for installing the fixing device 5.

[0028] The quantitative control hopper 3 comprises a tipping bucket 31, a sector gear 32, a clamping rod 33, a rotating connecting shaft 34 and a sliding support rod 35. One end of the tipping bucket 31 is fixedly connected to the rotating connecting shaft 34, one end of the rotating connecting shaft 34 is rotatably connected to the auxiliary mounting plate 22, and the other end of the rotating connecting shaft 34 is rotatably connected to the driving mounting plate 21, so that the tipping bucket 31 can rotate around the rotating connecting shaft 34 under the action of the driving device 4. The sector gear 32 is fixedly connected to the rotating connecting shaft 34, and the sector gear 32 is engaged with the gear 42 in the driving device 4 to achieve power transmission. The side wall of the tipping bucket 31 is welded with the clamping rod 33 for connecting the fixing device 5, and when it is necessary to fix the tipping bucket 31, the clamping rod 33 can cooperate with the fixing device 5 to fix the tipping bucket 31 at a specific position. The top of the sliding support rod 35 is rotatably connected to the side wall of the tipping bucket 31, and the sliding support rod 35 is slidingly inserted into the support beam 11. The support beam 11 is provided with a clamping support electromagnet 12 at a position in contact with the side wall of the sliding support rod 35. During the rotation of the tipping bucket 31, the sliding support rod 35 always maintains a state of being perpendicular to the ground and is adsorbed by the clamping support electromagnet 12, thereby playing a role in supporting and stabilizing the tipping bucket 31. The clamping support electromagnet 12 can be placed on one side or on both sides of the sliding support rod 35.

[0029] It should be noted that when the clamping support electromagnet 12 is placed on both sides of the sliding support rod 35, the clamping support electromagnet 12 can be provided with an elastic member on the side connected to the support beam 11. The elastic member can be a spring with a large elastic coefficient. This design is to avoid the gap between the sliding support rod 35 and the clamping support electromagnets 12 on both sides, causing a suspended state when both clamping support electromagnets 12 are turned on at the same time.

[0030] The driving device 4 is used to drive the rotation of the quantitative control hopper 3 to realize the control of the discharge flow. The driving device 4 comprises a motor 41, a gear 42 and an extension connecting rod 43. The motor 41 is detachably connected to the side wall of the driving mounting plate 21, the driving end of the motor 41 is fixedly connected to one end of the extension connecting rod 43, the other end of the extension connecting rod 43 is connected to the gear 42 through a spline, and the gear 42 is engaged with the sector gear 32. When the motor 41 is started, the gear 42 is driven to rotate through the extension connecting rod 43, and the sector gear 32 is driven to rotate through the gear 42, thereby realizing the rotation of the quantitative control hopper 3. By controlling the rotation speed and direction of the motor 41, the rotation angle and speed of the quantitative control hopper 3 can be accurately controlled, thereby realizing the accurate control of the discharge flow.

[0031] The fixing device 5 is used to fix the ration control hopper 3 when the ration control hopper 3 is not needed to discharge, preventing the magnesium sand from flowing out accidentally. It comprises a rotating hook 51, a threaded rod 52, a connecting block 53 and a fixed electromagnet 54. The rotating hook 51 comprises a rotating end and a hook end. The rotating end of the rotating hook 51 is rotatably connected to the sidewall of the connecting block 53. The connecting block 53 is threadedly connected to the threaded rod 52. The threaded rod 52 is connected to the auxiliary mounting table 23 through a nut. The fixed electromagnet 54 is embedded in the bottom surface of the auxiliary mounting table 23. The fixed electromagnet 54 faces the rotating hook 51. The rotating hook 51 can be made of iron or can be provided with a heteropolar magnet on the contact surface of the rotating hook 51 and the fixed electromagnet 54.

[0032] When the ration control hopper 3 needs to be fixed, the rotating hook 51 rotates under the action of gravity or external force. The hook end of the rotating hook 51 hooks the clamping rod 33 on the ration control hopper 3. At the same time, the fixed electromagnet 54 is powered to generate a magnetic force to attract the rotating hook 51, so that the rotating hook 51 is more firmly fixed on the auxiliary mounting table 23, thereby achieving the fixation of the ration control hopper 3. When the ration control hopper 3 needs to be discharged, the fixed electromagnet 54 is powered off to lose the magnetic force. The rotating hook 51 rotates under the action of a spring or other reset device to release the clamping rod 33. The ration control hopper 3 rotates under the action of the driving device 4 to achieve the discharge.

[0033] Working principle:

[0034] When high-purity magnesium sand needs to be stored, the magnesium sand is poured into the hopper 2. When the magnesium sand needs to be discharged, the fixed electromagnet 54 is powered on, and the rotating hook 51 is upwardly rotated and adsorbed by the fixed electromagnet 54. Then, the motor 41 is started to drive the gear 42 to rotate through the extension connecting rod 43, so that the gear 42 drives the sector gear 32 to rotate, thereby rotating the tipping bucket 31 of the ration control hopper 3 around the rotating connection shaft 34 to achieve the discharge. By controlling the rotation speed and direction of the motor 41, the discharge flow can be accurately controlled.

[0035] When the magnesium sand does not need to be discharged, the motor 41 is stopped, and the fixed electromagnet 54 is powered off. The rotating hook 51 is downwardly rotated due to its own gravity, so that the hook end of the rotating hook 51 hooks the clamping rod 33. Then, the fixed electromagnet 54 is powered on to attract the rotating hook 51, thereby fixing the ration control hopper 3 at a specific position to prevent the magnesium sand from flowing out accidentally.
