Description

Technical Field

[0001] This utility model relates to the technical field of zeolite molecular sieve synthesis equipment, and in particular to a mixing device for the synthesis and processing of zeolite molecular sieves. Background Technology

[0002] VOCs adsorbent all-silica Beta molecular sieves have advantages such as high silica-to-alumina ratio, large specific surface area, and good hydrophobicity. During synthesis, thorough mixing of the raw materials is required. Crystallization synthesis of molecular sieves requires a crystallization reactor, which is available in vertical and horizontal types. Vertical reactors typically operate in batches, adding materials to the reactor for each production run, reacting, and then discharging the product. This is suitable for experimental research, multi-variety small-batch production, and scenarios requiring precise control of reaction conditions. Its disadvantage is low production capacity. Horizontal reactors generally operate continuously, suitable for large-scale production. Materials continuously enter the reactor from one end, gradually moving to the other end under stirring while reacting, and finally continuously discharging the product from the outlet, achieving a highly efficient and stable production process. The horizontal design of the reactor allows for smooth material flow within the reactor, reducing material stagnation and dead zones, and minimizing localized overheating or overcooling. However, its disadvantage is that the internal structure may cause variations in material flow velocity, affecting reaction uniformity and leading to inconsistent product quality.

[0003] The purpose of this invention is to overcome the defects in the prior art and provide a synthesis and processing device for VOCs adsorbent all-silica Beta molecular sieves, which promotes full mixing of raw materials, avoids uneven mixing, and ensures the synthesis effect.

[0004] The purpose of this utility model is achieved as follows: A synthesis and processing device for VOCs adsorbent all-silica Beta molecular sieve includes a synthesis tank mounted on a mounting frame. A drive motor is mounted on the mounting frame above the synthesis tank. A hopper and a feeder are respectively provided on both sides of the drive motor. The lower part of the hoppers is provided with feeders. The feeders are connected to a material pipe to transport raw materials into the synthesis tank. The output shaft of the drive motor extends into the synthesis tank and is connected to a bevel gear connection structure for transmission. A stirring mechanism and a pushing mechanism are respectively connected to both sides of the bevel gear connection structure. The stirring mechanism and the pushing mechanism are arranged opposite each other in the synthesis tank along the inner wall of the synthesis tank. A discharge push rod is connected to the end of the pushing mechanism near the outlet of the synthesis tank. A discharge valve is provided on the outlet of the synthesis tank.

[0005] In operation, raw materials are added into the synthesis tank through hopper one and hopper two. The stirring mechanism and the pushing mechanism inside the synthesis tank are driven by the drive motor one. The stirring mechanism continuously stirs and mixes the raw materials in the synthesis tank, and the pushing mechanism continuously pushes and conveys the raw materials in the synthesis tank from bottom to top, so as to promote continuous stirring and mixing of the raw materials inside the synthesis tank, avoid uneven mixing of materials in layers, and improve the uniformity of the product.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] First, in this device, the material at the bottom of the synthesis tank is continuously pushed upward by the pushing mechanism, which mixes it thoroughly with the material at the top, promotes uniform mixing of the material inside the synthesis tank, avoids material stratification, and ensures the quality of product synthesis.

[0009] Third, the synthesis tank of this device is movably connected to the mounting frame through a plane bearing. The drive motor drives the synthesis tank to rotate within a certain limit along the horizontal direction of the plane bearing.

[0013] Furthermore, the bevel gear connection structure includes a bevel gear one that is driven and connected to the output shaft of a drive motor. Bevel gear two and bevel gear three are perpendicularly meshed on both sides of bevel gear one. One side of bevel gear two is connected to bevel gear four via a transmission rod.

One side of bevel gear three is connected to bevel gear six via a transmission rod. Bevel gear six is ​​meshed with bevel gear seven. Bevel gear seven is driven and connected to the pushing rod of the pushing mechanism.

[0014] Furthermore, the synthesis tank is an inverted cone shape that is wider at the top and narrower at the bottom. The upper and lower parts of the synthesis tank are movably connected to the mounting frame via planar bearings fixedly mounted on support rod one. The mounting frame is also provided with support rod two, and drive motor two is fixedly mounted on support rod two. The output shaft end of drive motor two is connected to a gear, which meshes with a gear ring set along the outer periphery of the synthesis tank. Drive motor two drives the gear to rotate, causing the synthesis tank to rotate to a certain extent in the horizontal direction of the planar bearing.

[0015] Furthermore, the discharge valve is a disc valve. Attached Figure Description
