Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a device for quantitative dispensing of chemical raw materials. Background Technology

[0002] Chemical industry, or chemical production technology, encompasses all processes that use chemical methods to alter the composition or structure of substances or synthesize new substances. The resulting products are called chemicals or chemical products. For most chemical raw materials, the process of mixing and processing requires adding the materials first, followed by mixing. However, in most cases, the materials are directly added to a mixing tank, which prevents rapid and thorough mixing, thus affecting the efficiency of the mixing process.

[0003] A search revealed Chinese patent CN219784641U, which discloses a chemical raw material quantitative dispensing device, including a feeding barrel. An internal rotating plate is rotatably connected to the inner side of the feeding barrel. External teeth are fixedly installed on the surface of the internal rotating plate. An internal sliding groove is opened on the inner side of the feeding barrel. An internal guide rod is fixedly installed on the inner wall of the internal sliding groove. An internal guide plate is slidably connected to the surface of the internal guide rod.

[0004] The device uses an external sealing plate that is driven to reset by an elastic component to form a seal on the discharge trough. This method ensures that when multiple chemical raw materials are discharged, the chemical raw materials can be quantitatively added within a certain range. This ensures the fullness of the sequential feeding and mixing of multiple chemical raw materials, and improves the shortcomings of traditional chemical material mixing operations that do not have quantitative feeding and mixing operations. Thus, the device improves the efficiency of quantitative feeding and mixing of materials.

[0005] However, the device also has the following problems. The device drives the internal guide plate to move by the interaction between the external teeth set on the outer peripheral wall of the internal rotating plate and the external tooth groove opened on the surface of the internal guide plate. Then, the internal guide plate is reset by the elastic component to achieve quantitative material discharge. However, in actual use, when the elastic force of the elastic component is at its maximum, the contact area between the external teeth and the external tooth groove is small, which can easily lead to damage to the external teeth or the external tooth groove, making it difficult to extend the service life of the device.
