CN203540735U - Nozzle of convection drying oven for drying coated power lithium ion battery - Google Patents

Abstract

The utility model discloses a nozzle for coating and drying convection oven for power lithium-ion batteries, which comprises a casing with an open lower end, an air inlet plate at the upper end of the casing, and an inner container connected inside the casing , a cavity is formed at the upper end of the inner tank, the cavity is facing the air inlet plate, and a slit for air outlet is formed between the two sides outside the inner tank and the inner wall of the housing, and the lower end of the slit is air outlet. In the utility model, an inner tank is arranged in the housing, and a cavity for buffering and redistribution after the gas enters is formed above the inner tank, so that the drying gas entering from the air distribution plate can pass through the narrow space of the inner tank at a stable flow rate and flow rate. Slit spraying not only weakens the flow velocity of the gas, but also changes the flow direction of the gas, reducing the impact of the gas. The slit air outlet can act on the workpiece in a linear shape, so that the drying is more uniform and the quality is improved. At the same time, the width of the air outlet is adjustable, so that the flow rate and flow rate of the air outlet can be adjusted to meet the drying needs of different workpieces.

Description

Nozzles for coating and drying convection ovens for power lithium-ion batteries

Technical field:

The utility model belongs to the technical field of drying devices, in particular to a nozzle used in an oven.

Background technique

The nozzle belongs to the air outlet device of the oven, and the drying gas in the oven is sprayed onto the workpiece to be dried through the nozzle to dry the workpiece. The structure of the existing nozzles is all a small nozzle with a circular air outlet; or a blast pipe is used to open spray holes on the pipe. Whether it is a nozzle or a nozzle, it is finally sprayed through the hole, which is relatively concentrated and has a certain speed, which is easy to cause impact damage to the surface of the workpiece, and the uneven distribution of the airflow affects the drying effect of the workpiece.

Contents of the invention

The technical problem to be solved by the utility model is to provide a nozzle that discharges air in a linear manner and distributes the air evenly, aiming at the deficiencies of the above-mentioned prior art.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A nozzle for an oven, characterized in that it includes a casing with an open lower end, an air inlet plate is formed at the upper end of the casing, an inner container is connected to the inside of the casing, and a container is formed at the upper end of the inner container. The chamber is facing the air inlet plate, and a slit for air outlet is formed between the two sides of the inner tank and the inner wall of the housing, and the lower end of the slit is an air outlet.

The air outlet intersects with the air inlet of the air inlet plate to form an acute angle.

A slit width adjustment mechanism is also connected between the inner tank and the housing, the mechanism includes a strip-shaped adjustment hole arranged on the housing and a wing nut arranged in the adjustment hole, the wing nut The inside is fixedly connected with the inner bag.

Compared with the prior art, the utility model nozzle has the following advantages:

The utility model sets an inner tank in the shell, and forms a cavity above the inner tank for buffering and redistribution after the gas enters, so that the drying gas entering from the air distribution plate can pass through the narrow space of the inner tank at a stable flow rate and flow rate. Slit spraying not only weakens the flow velocity of the gas, but also changes the flow direction of the gas, reducing the impact of the gas. The slit air outlet can act on the workpiece in a linear shape, so that the drying is more uniform and the quality is improved. At the same time, the width of the air outlet is adjustable, so that the flow rate and flow rate of the air outlet can be adjusted to meet the drying needs of different workpieces.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1 and Figure 2, the utility model is used for the nozzle of the power lithium-ion battery coating drying convection oven, including the shell 2, the inner tank 5 and the air inlet plate 1, wherein the air inlet plate 1 is fixed on the shell The upper end of the body 2, the liner 5 is fixed on the two sides of the housing 3 through the side wing nuts 3 and can be adjusted up and down. A cavity 6 is formed on the upper end of the inner tank 5, the cavity 6 faces the air inlet plate 1, and a slit 7 for air outlet is formed between the inner tank 5 and the housing 2, and the lower end of the slit 7 is an air outlet. The air outlet intersects with the air inlet of the air inlet plate to form an acute angle. The dry gas entering from the air inlet plate 1 first enters the cavity 6 and then is ejected from the upper end of the inner tank through the slit 7 .

A slit width adjustment mechanism is also connected between the inner liner and the housing, which includes a strip-shaped adjustment hole 4 arranged on the housing and a butterfly nut 3 arranged in the adjustment hole. It is fixedly connected with the liner. the
