Description

Technical Field

[0001] The utility model belongs to the technical field of fine chemical industry, in particular to a quantitative feeding device for fine chemical industry. Background Art

[0002] In the process of fine chemicals, during the process of batching and adding ingredients, it is necessary to control the addition process of raw materials more precisely. In the existing process of adding raw materials, in order to meet the requirements of timing and quantity, the raw materials need to be weighed and added in advance. This method increases the labor intensity of the staff when used, and it is easy to forget to add materials or add materials untimely. Therefore, quantitative feeding devices have appeared, but traditional quantitative feeding devices cannot preset the amount in advance and need to be adjusted on site when used, which is too inefficient.

[0003] After searching, the Chinese patent document (authorization announcement number CN217392332U) discloses a quantitative feeding device for fine chemicals, including a storage barrel, a feeding port connected to the inside and outside is opened on the lower end surface of the storage barrel, and a floating plate for monitoring the liquid level is provided in the inner cavity of the storage barrel. In the time period when the notch and the feeding port are docked, the raw materials can be added into the external equipment. When the notch and the feeding port are misaligned, the raw materials are stopped from being added. The diameter of the gear is much smaller than the diameter of the turntable, so that a more precise adjustment effect can be achieved during the adjustment process. By controlling the rotation speed of the gear, the docking time of the notch and the feeding port can be controlled, thereby controlling the amount of material added in a single feeding process. Although the amount of material added can be adjusted, it cannot be adjusted in advance, and on-site adjustment is required when it is used, which is too inefficient. Utility Model Content

The inner cavity of the quantitative box 3 is provided with an adjusting plate 5 for adjusting the space utilization rate. The outer periphery of the adjusting plate 5 is bonded with a sealing frame 6 made of rubber material for improving the sealing performance to ensure that the chemical raw materials will not flow into the space where the adjusting threaded rod 8 is located. A threaded pipe 7 is embedded in the side of the quantitative box 3. The threaded pipe 7 is threaded with the adjusting threaded rod 8. The adjusting threaded rod 8 is rotatably connected to the adjusting plate 5 through a bearing. The adjusting threaded rod 8 is rotated in advance to change the position of the adjusting plate 5.

The curved surface of the arc plate 14 is bonded with an anti-slip pad, and the space usage volume in the quantitative box can be understood from the data of the measuring rod 11. The usage volume is not only the volume of the quantitative box 3, but also a part of the volume attached to the main pipe 41 and the feeding pipe 2. It can be measured in advance using equipment. After accurate understanding, it can be easily adjusted in various ways later. The tightening threaded rod 13 is rotated to make the arc plate 14 tighten and fix the measuring rod 11, thereby indirectly ensuring the stability of the adjusting plate 5.

After completion, the valve is closed, and the valve of the feeding pipe 2 is opened to discharge the material.

[0046] The servo motor 10 and the valve are both conventional instruments, and their working principles, sizes and models are irrelevant to the problems solved by this application, so they will not be described in detail. The control method of the utility model is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
