Description

Technical Field

[0001] The utility model relates to the technical field of latex powder production drying equipment, in particular to a dispersible latex powder spray drying device. Background Art

[0002] In the traditional latex powder production process, drying is a key step, which directly affects the product quality and production efficiency. Traditional drying methods usually include oven drying, fluidized bed drying, etc. Although these methods can meet production needs to a certain extent, they have some limitations and shortcomings. Traditional drying equipment is often bulky, energy-intensive, and has low drying efficiency, which leads to increased production costs. In addition, since the equipment is fixed, it cannot quickly adapt to the adjustment of production scale and is not flexible enough for small batch production. During the drying process, the uniformity of the drying of the material is difficult to ensure, and it is easy to partially over-dry or under-dry, affecting product quality. For example, in oven drying, the outside of the material may dry faster than the inside, resulting in inconsistent product performance. Traditional drying equipment is complex to operate and requires professional operators to monitor and adjust, which increases labor costs. At the same time, the equipment startup and shutdown procedures are cumbersome, and the response speed to emergency orders is slow. Due to the large size and heavy weight of traditional drying equipment, it is not easy to move, which limits its flexibility at the production site. Once the equipment is installed, it is difficult to adjust or rearrange it according to production needs. The use of high-pressure tanks and nozzle assemblies requires strict safety measures to prevent safety accidents caused by excessive pressure. The safety design of traditional equipment is insufficient and there may be hidden dangers. Utility Model Content

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0035] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application.

[0036] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "plurality" is two or more.

[0037] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] As in the background art, traditional drying equipment is often bulky, energy-consuming, and has low drying efficiency, resulting in increased production costs. In addition, due to the fixed equipment, it is unable to quickly adapt to the adjustment of production scale and is not flexible enough for small-batch production. During the drying process, it is difficult to ensure the drying uniformity of materials, and it is easy to have the situation of partial over-drying or under-drying, which affects product quality. For example, in oven drying, the outside of the material may dry faster than the inside, resulting in inconsistent product performance. Traditional drying equipment is complex to operate and requires professional operators for monitoring and adjustment, increasing labor costs. At the same time, the equipment startup and shutdown procedures are cumbersome, and the response speed to emergency orders is slow. Due to the large size and heavy weight of traditional drying equipment, it is not easy to move, which limits its flexibility at the production site. This makes it difficult to adjust or re-layout the equipment according to production needs once it is installed. The use of high-pressure tanks and nozzle assemblies requires strict safety measures to prevent safety accidents caused by excessive pressure. The safety design of traditional equipment is insufficient and potential hazards may exist.

[0039] To improve the above problems, a spray drying device for dispersible latex powder proposed in the present application realizes the mobile operation of the entire device through a box body arranged on a bottom plate, universal wheels on the bottom plate, and a handrail on the bottom plate, improving the flexibility and adaptability of the equipment. The connection between the top of the chamber and the high-pressure tank, and the nozzle assembly connected to the bottom enable the material to enter the nozzle under the action of a high-pressure air pipe and generate fine and uniform droplets through an air flow nozzle, which helps the latex to dry quickly after entering the drying chamber. At the same time, a manual stirring assembly arranged at the top of the chamber can keep the material in the chamber in a stirred state, further improving the drying uniformity and efficiency. In addition, the design of this device also pays attention to safety, and improves the safety performance of the equipment by setting safety measures such as closable openings and pressure control systems.
