Description

Technical Field

[0001] This utility model relates to the field of chemical product technology, and in particular to a wet material silo for manufacturing chemical products. Background Technology

[0002] Chemical industry is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition and structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process. The products obtained are called chemical products. Initially, these products were produced in small workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry. Currently, in the production process of chemical products, wet storage silos are needed to store chemical raw materials. During the storage of chemical raw materials in wet storage silos, the chemical raw materials become damp and are prone to clumping.

[0003] For example, a wet material silo for chemical product manufacturing disclosed in Chinese patent literature (publication number: CN221478318U) uses a crushing mechanism to break up clumps of chemical raw materials, reducing the amount of chemical raw materials adsorbed inside the wet material silo and facilitating the transportation and use of chemical raw materials. This solves the problem that chemical raw materials are easily agglomerated during storage in wet material silos, and it is inconvenient to break up the clumps of chemical raw materials using an air vibrator, thus affecting the efficiency of chemical raw material transportation and use.

[0004] However, the two rotating rods can only drive the spiral crusher to rotate and crush within the wet silo body, which results in a very limited crushing range. In actual use, only the agglomerated chemical raw materials within the direct contact range of the spiral crusher can be effectively crushed, while the remaining uncontacted materials are still prone to agglomeration and accumulation. This not only affects the overall quality of the chemical raw materials in the wet silo, but may also cause blockages and other problems during subsequent transportation and use.

[0005] Secondly, although the scraper can scrape off material from the inner wall of a part of the wet silo body by rotating along the rotating rod, this local cleaning method is difficult to completely and effectively prevent the accumulation of material on the silo wall. Due to the limited range of the scraper, most of the silo wall area cannot be cleaned in time. Over time, these uncleaned areas may accumulate more and more material, further affecting the smoothness of material discharge. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies. Currently, the positioning and rotating spiral crusher has a limited crushing range for materials, and the working range of the scraper cannot cover the entire bin wall, which greatly affects the problem of stable material discharge.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wet silo for chemical product manufacturing includes a silo body. An agglomeration and crushing mechanism is installed inside the silo body. This mechanism includes an internal gear ring, the upper end of which is fixedly connected to the inner top wall of the silo body. A discharge pipe is fixedly connected to the lower end of the silo body. A drive rod is rotatably connected to the upper inner wall of the silo body via a bearing. A worm gear is fixedly sleeved on the upper outer side of the drive rod. The lower end of the drive rod penetrates the silo body and extends into the discharge pipe. A crushing rod is fixedly connected to the outside of the drive rod. Multiple crushing rods are divided into five groups and arranged in a linear array. A spiral conveyor plate is fixedly sleeved on the outside of the drive rod, and the outer side of the spiral conveyor plate contacts the inner wall of the discharge pipe.

[0009] Preferably, the drive rod is externally fixedly connected to symmetrically distributed rotating blocks, and the lower end of the rotating blocks is fixedly connected to a support block.

[0010] Preferably, the lower end of the support block is fixedly connected to the outside of the drive rod, and one end of the rotating block is fixedly connected to an arc-shaped scraper, the outer side of which contacts the inner wall of the hopper body.

[0011] Preferably, the upper end of the rotating block is provided with a mounting hole, and the inner wall of the mounting hole is rotatably connected to a rotating rod through a bearing. A gear is fixedly sleeved on the upper end of the rotating rod.

[0012] Preferably, the tooth surface of the gear meshes with the tooth surface of the internal gear ring, and a spiral crushing disc is fixedly sleeved on the outside of the rotating rod.

[0013] Preferably, a servo motor is fixedly installed at the upper end of the hopper body, and a worm gear is fixedly installed on the output shaft of the servo motor through a coupling.

[0014] Preferably, the outer surface of the worm meshes with the tooth surface of the worm wheel, and the upper end of the hopper body is fixedly connected to a feed pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the agglomeration crushing mechanism enables the use of a drive rod and a rotating block to drive an arc-shaped scraper to scrape off the material adhering to the entire inner wall of the hopper. When the rotating block rotates, the gear and internal gear ring work together to drive the rotating rod to rotate synchronously. This causes the rotating rod to drive the spiral crushing blade to rotate on its own axis while simultaneously revolving along the drive rod. This allows for the thorough crushing of the agglomerated material inside the hopper. Furthermore, the spiral conveyor plates work together to stably transport the crushed material out of the hopper.

[0026] Example

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a wet material silo for chemical product manufacturing, including a silo body 1. The silo body 1 is cylindrical in shape and made of high-strength corrosion-resistant material to ensure that it will not be corroded by chemical substances during the storage of chemical products. Its inner wall is specially treated to have a low coefficient of friction so that the material can flow smoothly. The silo body 1 is composed of a cylinder and a cover, which are fixedly connected by bolts.

[0028] The silo body 1 is equipped with an agglomeration crushing mechanism, which includes an inner toothed ring 2. The upper end of the inner toothed ring 2 is fixedly connected to the inner top wall of the silo body 1, and the lower end of the silo body 1 is fixedly connected to a discharge pipe 21. The connection between the discharge pipe 21 and the silo body 1 is sealed to prevent material leakage.

[0029] The upper inner wall of the hopper body 1 is rotatably connected to a drive rod 22 via a bearing. The drive rod 22 is made of high-quality alloy steel and has sufficient strength and rigidity to withstand the loads brought by various crushing and conveying mechanisms. A worm gear 23 is fixedly sleeved on the upper outer side of the drive rod 22. The connection between the worm gear 23 and the drive rod 22 adopts an interference fit and is further fixed by a key connection to ensure that there is no relative slippage during rotation.

[0030] The lower end of the drive rod 22 passes through the hopper body 1 and extends into the discharge pipe 21. A crushing rod 24 is fixedly connected to the outside of the drive rod 22. The crushing rod 24 is made of high-strength wear-resistant material, and its shape and size are optimized to improve the crushing effect on agglomerated materials. Multiple crushing rods 24 are divided into five groups and are distributed in a linear array.

[0031] A spiral conveyor blade 25 is fixedly sleeved on the outside of the drive rod 22. The outer side of the spiral conveyor blade 25 contacts the inner wall of the discharge pipe 21. The spiral conveyor blade 25 is made of wear-resistant rubber or alloy steel, and its pitch and diameter are designed according to the size of the discharge pipe 21 and the characteristics of the material.

[0032] The drive rod 22 is externally fixedly connected to symmetrically distributed rotating blocks 26. The lower end of the rotating block 26 is fixedly connected to a support block 27. The support block 27 and the rotating block 26 are connected by welding or bolts to ensure that there will be no loosening during rotation. The support block 27 is used to improve the stability of the rotating block 26 when it rotates.

[0033] The lower end of the support block 27 is fixedly connected to the outside of the drive rod 22. One end of the rotating block 26 is fixedly connected to an arc-shaped scraper 28. The outer side of the arc-shaped scraper 28 contacts the inner wall of the hopper body 1. The arc-shaped scraper 28 is made of wear-resistant rubber or alloy steel, and its shape matches the shape of the inner wall of the hopper body 1 to ensure that the material adsorbed on the hopper wall can be effectively scraped off.

[0034] The upper end of the rotating block 26 is provided with a mounting hole 29. The inner wall of the mounting hole 29 is rotatably connected to the rotating rod 210 through a bearing. The diameter of the mounting hole 29 is designed according to the size of the rotating rod 210 to ensure that the rotating rod 210 can rotate freely in the mounting hole 29. A gear 211 is fixedly sleeved on the upper end of the rotating rod 210.

[0035] The tooth surface of gear 211 meshes with the tooth surface of internal gear ring 2. The rotating rod 210 is externally fixedly sleeved with a spiral crushing blade 212. The spiral crushing blade 212 is made of high-strength wear-resistant material. Its pitch and diameter are designed according to the size of the hopper body 1 and the characteristics of the material. The surface of the spiral crushing blade 212 is provided with sharp protrusions to improve the crushing effect on agglomerated materials.

[0036] A servo motor 213 is fixedly installed on the upper end of the hopper body 1. The servo motor 213 is a high-performance, high-precision servo motor with good speed regulation performance and overload capacity. The servo motor 213 is fixed to the upper end of the hopper body 1 by bolts or welding to ensure that the installation is firm and reliable.

[0037] The output shaft of the servo motor 213 is fixedly mounted with a worm gear 214 via a coupling. The worm gear 214 is made of high-quality alloy steel and is precision machined to ensure the meshing accuracy with the worm wheel 23.

[0038] The outer surface of the worm 214 meshes with the tooth surface of the worm wheel 23. The upper end of the hopper body 1 is fixedly connected to the feed pipe 3. The feed pipe 3 is made of the same corrosion-resistant material as the hopper body 1. Its diameter is designed according to the actual feeding requirements. The feed pipe 3 is equipped with a feed valve to control the flow rate of the material. The connection between the feed pipe 3 and the hopper body 1 is sealed to prevent material leakage.

[0039] The working process of this utility model:

[0040] Step 1: When discharging, open the control valve of the discharge pipe 21, and then start the servo motor 213 to drive the worm gear 214 to rotate. The rotation of the worm gear 214 drives the drive rod 22 to rotate through the meshing worm wheel 23. The rotation of the drive rod 22 drives the arc scraper 28 through the rotating block 26 to scrape off the material adsorbed on the inner wall of the hopper body 1, so that it falls into the bottom of the hopper and is crushed by the rotation of the crushing rod 24 to avoid the formation of clumps.

[0041] Step two, when the drive rod 22 rotates, it also drives the rotating rod 210 to rotate through the rotating block 26. The rotation of the rotating rod 210 drives the spiral crushing disc 212 to rotate through the cooperation of the gear 211 and the internal gear ring 2. When the spiral crushing disc 212 rotates, it crushes the material agglomerates. In addition, the rotating block 26 drives the spiral crushing disc 212 to revolve, so that the spiral crushing disc 212 can fully crush the material inside the hopper body 1. The rotation of the spiral crushing disc 212 can drive the material to rise and turn, which facilitates the full crushing in conjunction with the rotation of the crushing rod 24.

[0042] Step 3: The rotation of the drive rod 22 also drives the spiral conveyor 25 to rotate. The rotation of the spiral conveyor 25, in conjunction with the discharge pipe 21, ensures that the crushed material is continuously and stably discharged, avoiding blockage in the discharge pipe 21 and greatly improving the stability of the discharge.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
