Description

Technical Field

[0001] The utility model relates to the field of adding devices, in particular to a catalyst adding device for preparing light stabilizers. Background Art

[0002] Light stabilizer is an additive that extends the life of polymer products. It can shield or absorb ultraviolet energy, quench singlet oxygen, and decompose hydroperoxides into inactive substances. It can eliminate or slow down the possibility of photochemical reactions of polymers under light radiation, and prevent or delay the process of light aging. When preparing light stabilizers, an addition device must be used to add the catalyst.

[0003] Although the existing adding device can store and manually add catalysts, there are still other problems during use, such as poor adding effect. The existing adding method is to manually control the opening and closing of the pipe valve, and it is impossible to obtain the accurate amount of catalyst added to the processing equipment. Therefore, it is necessary to rely on the experience of the staff to make judgments, and it is easy to add too much or too little. In addition, it does not have an automatic translation function. When adding the catalyst, the device will occupy the feed port above the processing equipment, making it difficult to add other raw materials. Therefore, it is used in a take-as-you-go manner, which is time-consuming and labor-intensive. In order to solve the above problems, we propose a catalyst adding device for the preparation of light stabilizers. Utility Model Content

[0006] The above technical solution can have an automatic translation function, which reduces the burden on personnel to take and place the device, avoids obstruction of the feed port when other raw materials are added, has good flexibility, and can achieve good adding effects. It can accurately control the amount of catalyst added in a quantitative manner to avoid excessive or insufficient addition, and has high practicality.

[0007] The utility model is further configured as follows: a slide rail is bolted inside the mounting frame, and a slider is welded on the top of the threaded plate and is slidably connected to the slide rail.

[0008] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from flipping during the left and right movement.

[0009] The utility model is further configured as follows: a protective cover is bolted to one side of the mounting frame.

[0010] By adopting the above technical solution, the motor can be protected by providing a protective cover, thereby preventing the motor from being damaged by collision with foreign objects.

[0011] The utility model is further configured as follows: a mounting hole is provided at the bottom of the mounting frame.

[0012] By adopting the above technical solution and providing the mounting holes, it is convenient for personnel to fix the mounting bracket to the processing equipment with screws, thereby reducing the trouble of temporary drilling.

[0013] The utility model is further configured as follows: an observation port is integrally stamped on one side of the storage box.

[0014] By adopting the above technical solution and providing the observation port, it is possible for personnel to observe and understand the remaining amount of catalyst in the storage box.

[0015] The utility model is further configured as follows: a dust cover is welded to the bottom of the material storage box, and the top end of the metering cylinder extends to the interior of the dust cover.

[0016] By adopting the above technical solution, the dustproof cover is provided to achieve a dustproof function, preventing dust in the air from falling into the opening at the top of the metering cylinder.

[0017] The utility model is further configured as follows: the threaded rod and the threaded plate are both made of stainless steel.

[0018] By adopting the above technical solution, the threaded rod and the threaded plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. The utility model first fixes the mounting bracket to the processing equipment with screws. After the mounting bracket is fixed, the motor is started. After starting, the motor drives the threaded rod to rotate. When the threaded rod rotates, it drives the threaded plate to move to the left through the cooperation of the slide rail and the slider. When the threaded plate moves to the left, it drives the second discharge pipe valve to be above the equipment feed port. It can have an automatic translation function, which reduces the burden of personnel on taking and placing the device, avoids blocking the feed port when other raw materials are added, and has good flexibility.

[0021] 2. The utility model opens the first discharge pipe valve, which will cause the catalyst in the storage box to fall downward into the metering cylinder. The catalyst will increase the weight of the metering cylinder when falling in. The weighing sensor can transmit the increased weight in the metering cylinder to the PLC controller. The PLC controller will display the information through the display screen after receiving the feedback. When the weight in the metering cylinder reaches a predetermined value, the first discharge pipe valve will be controlled to automatically close and the second discharge pipe valve will be controlled to automatically open, thereby achieving a good adding effect and accurately controlling the amount of catalyst added in a quantitative manner to avoid excessive or insufficient addition, and the utility model is highly practical.
