Description

Technical Field

[0001] This utility model relates to the field of chromium formate preparation technology, and in particular to a spiral feeder for chromium formate preparation. Background Technology

[0002] Chromium formate is an organic compound that appears as a green or colorless crystalline powder and is widely used in oxidation reactions, alcohol oxidation, and selective aldehyde oxidation in chemical synthesis. The preparation of chromium formate requires feeding its raw materials, which is done using a screw feeder. Patent specification CN210417144U discloses a screw feeder, including a feeder frame and a feed hopper mounted on the frame. It also includes a feed pipe with a feed screw inside. The outer diameter of the feed screw matches the inner diameter of the feed pipe. The feed screw is driven by a three-phase asynchronous motor. The feed pipe includes a feed inlet and a feed outlet, with the feed inlet connected to the feed hopper. This utility model screw feeder transports paste and powder materials through a screw. The screw and the feeding pipe form a sealed cavity. The measurement of transported materials can be achieved by calculating the amount driven by the motor. At the same time, the device has low structural cost and is easy to promote. The connection height and angle of the feeding pipe can be adjusted by adjusting the angle of the feeding pipe and the support position of the feeding pipe bracket.

[0003] While the aforementioned technology allows for adjustment of the connection height and angle of the feeding pipe, in actual use, the raw materials can easily accumulate inside the feed box due to mutual compression, hindering the feeding process. Therefore, a screw feeder for the preparation of chromium formate is needed to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a screw feeder for the preparation of chromium formate, which solves the problem that in existing screw feeders, raw materials tend to accumulate inside the feed box due to mutual compression, thus affecting the feeding effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a screw feeder for the preparation of chromium formate, comprising a feed box and a screw feeder; a support frame is fixed to the bottom end of the feed box, the screw feeder is installed at the bottom end of the feed box, a screw blade shaft is installed inside the screw feeder, a motor is installed on one side of the bottom end of the feed box, a pulley is installed on one side of the motor, and a vibration structure is provided on one side of the pulley; the vibration structure includes a fixed plate, the fixed plate is fixed to one side of the feed box, a connecting block is installed at the middle position of the fixed plate, an impact column is installed on one side of the connecting block, and a limit block is installed at the bottom end of the fixed plate.

[0006] Preferably, the top end of the limiting block is connected to the bottom end of the connecting block, a connecting shaft is installed at one end of the pulley, and an eccentric disc is installed on the outside of the connecting shaft.

[0007] Preferably, the connecting block is inserted into the guide groove inside the fixing plate, and the connecting block and the fixing plate form a guide connection.

[0008] Preferably, the top of the feed box is provided with a screening structure, the screening structure includes a fixing bolt, the fixing bolt is fixed to both sides and both ends of the top of the feed box, a screening screen is installed on the top of the fixing bolt, and a nut is installed on the outside of the fixing bolt.

[0009] Preferably, the outer side of the fixing bolt is provided with external threads, and the inner side of the nut is provided with internal threads, forming a threaded connection between the fixing bolt and the nut.

[0010] Preferably, the fixing bolt passes through the mounting holes inside the screen mesh, and the fixing bolt and the screen mesh form an insertion structure.

[0011] Preferably, the outer side of the spiral blade shaft is provided with multiple sets of blades, and the multiple sets of blades are arranged at equal intervals on the outer side of the spiral blade shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating a vibration structure, after the motor starts, the eccentric disc rotates, causing the limit block to reciprocate. As the limit block moves, it causes the impact column on one side of the connecting block to reciprocate, impacting one side of the feed box and generating vibration. This vibration of the raw material inside the feed box prevents blockage. Furthermore, the vibration of the feed box also causes the screening screen to vibrate, resulting in better screening performance.

[0014] By incorporating a screening structure, impurities in the raw materials can be filtered out to improve their quality during preparation. This process ensures higher quality raw materials for the preparation of chromium formate. Attached Figure Description
