Description

Technical Field

[0001] This utility model relates to the field of sodium molybdate production technology, specifically a grinding device for sodium molybdate production. Background Technology

[0002] Sodium molybdate is an inorganic compound with the chemical formula Na₂MoO₄, usually appearing as colorless or white crystals. It is primarily used in chemical analysis, as a catalyst, and as a fertilizer component, and also finds applications in the glass and ceramics industries. Furthermore, sodium molybdate is significant in the preparation of other molybdenum compounds and as a raw material for molybdenum. The production of sodium molybdate typically requires the use of grinding equipment to grind the material.

[0003] Existing grinding devices for sodium molybdate production typically involve adding sodium molybdate material into a rotating drum and grinding it with abrasive. During discharge, the ground sodium molybdate material is discharged downwards using a receiving hopper. However, dust often diffuses outwards during discharge, easily causing significant dust accumulation in the working environment, which can affect operators and hinders the proper discharge of ground material. Therefore, we propose a grinding device for sodium molybdate production. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for sodium molybdate production, in order to solve the problem mentioned in the background art that dust usually diffuses outward during discharge, affecting the discharge operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for sodium molybdate production, comprising a support column, a base plate fixedly connected to the side wall of the support column, a rotating cylinder rotatably connected to the side wall of the support column, a discharge port at the top of the rotating cylinder, an inner mesh cylinder inside the rotating cylinder, a toothed ring fixedly connected to the outer circumference of the rotating cylinder, a gear fitted to the side wall of the toothed ring, supports on both sides of the gear, a drive motor fitted to the gear fixedly connected to the side wall of the supports, a transmission shaft fitted to the gear on the side wall of the supports, a hopper at the top of the base plate, a telescopic ring at the top of the hopper, a fitting ring inside the telescopic ring, and an upper push rod at the bottom of the fitting ring.

[0006] Preferably, a sealing plate is provided at the top of the discharge port, and telescopic rods are provided at both ends of the sealing plate.

[0007] Preferably, a fixing ring is provided on the outside of the telescopic rod, and the fixing ring is fixed to the side wall of the discharge port.

[0008] Preferably, a central column is provided inside the inner mesh cylinder, and a support rod connected to the inner mesh cylinder is fixed to the outer wall of the central column.

[0009] Preferably, the bottom of the hopper is provided with rollers, and the top of the bottom plate is provided with a groove that matches the rollers.

[0010] Preferably, the rotating cylinder is provided with a feeding gate on its side wall, and the support column has a rotating shaft that cooperates with the rotating cylinder through its side wall.

[0011] Preferably, the bracket is fixed to the top of the base plate and the bracket is fitted to the side wall of the rotating cylinder.

[0012] Preferably, inclined buckets are provided on both sides of the discharge port, and a protrusion that matches the discharge port is fixed to the outer wall of the discharge port.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a drive motor to rotate a gear, which in turn causes the rotating cylinder to rotate in conjunction with the support column via a toothed ring. Sodium molybdate material is ground inside the inner mesh cylinder with abrasive. The rotating cylinder is then rotated to a position where the discharge port faces downwards. The feeding hopper is positioned directly below the discharge port. The upper push rod extends, causing the fitting ring to move upwards and fit against the outer wall of the rotating cylinder. At this point, the telescopic ring extends and fits over the outside of the discharge port, allowing the ground material to be discharged into the feeding hopper when the discharge port opens. The telescopic ring's obstruction of the discharge port also helps to prevent dust from rising during discharge, reducing the spread of dust into the working environment and facilitating the discharge operation of the grinding device.

[0015] 2. When discharging materials, the extension rod of this utility model causes the sealing plate to move backward, thereby opening the discharge port. At this time, the material can be discharged from the discharge port. At the same time, the action of the inclined bucket makes the material discharge smoother, eliminating the trouble of manually opening the discharge door and saving manpower.

The ground powder can pass through the inner mesh cylinder 130 and be discharged between the rotating cylinder 110 and the inner mesh cylinder 130, and finally discharged from the discharge port 114. A toothed ring 112 is tightly welded to the outer circumference of the rotating cylinder 110. A gear 121 is fitted to the side wall of the toothed ring 112. The outer circumference of the toothed ring 112 has grooves that mesh with the gear 121. Supports 120 are provided on both sides of the gear 121, and the side walls of the supports 120 are fixedly connected to... The drive motor 122, which is connected to the power input end of the gear 121, is a commercially available drive motor with an external switch. A transmission shaft 123, tightly welded to the gear 121, is located on the side wall of the bracket 120. The two gears 121 are driven by the transmission shaft 123. A hopper 140 is located on the top of the base plate 101, and a telescopic ring 150 is located on the top of the hopper 140. The telescopic ring 150 is made of a retractable rubber sheet with deep pleats on its surface to facilitate the telescopic movement of the ring 150. Extending upwards, the telescopic ring 150 has an internal fitting ring 151 made of wear-resistant hard plastic strip. The bottom of the fitting ring 151 has an upper push rod 152. Each of the four corners of the fitting ring 151 has an upper push rod 152 that is bolted to the inside of the hopper 140. The upper push rod 152 is a common electric push rod. The four upper push rods 152 are electrically connected to the same external reversing switch, which is a common model and can control the simultaneous extension and retraction of the four upper push rods 152.

[0024] Specifically, a sealing plate 115 is provided at the top of the discharge port 114, and telescopic rods 116 are provided at both ends of the sealing plate 115. The telescopic rods 116 are common electric push rods on the market, and the two telescopic rods 116 are electrically connected to the same external reversing switch, which is a common model on the market.

[0025] Furthermore, a fixing ring is provided on the outside of the telescopic rod 116, and the fixing ring is fixed to the side wall of the discharge port 114 by bolts.

[0026] Furthermore, a central column 131 is provided inside the inner mesh cylinder 130. The two ends of the central column 131 are fixed to the inner wall of the rotating cylinder 110. The inner mesh cylinder 130 is made of stainless steel mesh with open ends. A support rod 132 connected to the inner mesh cylinder 130 is fixed to the outer wall of the central column 131 by bolts.

[0027] Furthermore, the bottom of the hopper 140 is provided with rollers 142, and the top of the bottom plate 101 is provided with a groove 141 that matches the rollers 142.

Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0032] Working principle: The drive motor 122 drives the gear 121 to rotate, which in turn causes the rotating cylinder 110 to rotate in conjunction with the support column 100 via the toothed ring 112. At this time, the sodium molybdate material is ground in the inner mesh cylinder 130 with the abrasive. Then, the rotating cylinder 110 is rotated to the position where the discharge port 114 faces downward. At this time, the feeding hopper 140 is positioned directly below the discharge port 114. Then, the upper push rod 152 extends, causing the contact ring 151 to move upward and fit against the outer wall of the rotating cylinder 110. At this time, the telescopic ring 150 extends and fits over the outside of the discharge port 114, thus allowing the material to be ground at the discharge port. When 114 is opened, the ground material is discharged into the hopper 140. The telescopic ring 150 blocks the outside of the discharge port 114, which helps to prevent dust from rising during discharge and reduces the spread of dust to the working environment, making it easier to discharge the grinding device. When discharging, the telescopic rod 116 extends, causing the sealing plate 115 to move backward, which opens the discharge port 114. At this time, the material can be discharged from the discharge port 114. At the same time, the action of the inclined bucket 111 makes the material discharge smoother, eliminating the trouble of manually opening the discharge door and saving manpower.
