Technical Field

The utility model relates to the field of cooling coils, in particular to a cooling coil.

Background

The reaction kettle is widely understood to be a container with physical or chemical reaction, and the heating, evaporating and cooling functions and the low-speed and high-speed mixing functions required by the process are realized through structural design and parameter configuration of the container.

Patent number CN202921313U discloses a reaction kettle, wherein the disclosed cooling tube is a common cooling tube on the market, and the cooling tube has small radiation space and low cooling efficiency.

Disclosure of Invention

The object of the present utility model is to provide a cooling coil.

The utility model has the innovation point that the spring-shaped branch pipes can increase the radiation range of the cooling coil pipe and improve the cooling efficiency.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a cooling coil comprises two annular main pipes which are arranged up and down, wherein one end of one annular main pipe is communicated with a water inlet pipe, the other end of the other annular main pipe is closed, one end of the other annular main pipe is connected with a water outlet pipe, the other end of the other annular main pipe is closed, a plurality of spring-shaped branch pipes are arranged between the two annular main pipes, and two ends of each branch pipe are respectively communicated with inner cavities of the two annular main pipes.

The cooling medium enters an annular main pipe from the water inlet pipe, then is split into branch pipes, finally is collected in another annular main pipe, and flows out from the water outlet pipe after being collected, the spring-shaped branch pipes prolong the flow path of the cooling medium, and the contact area of the branch pipes and materials to be cooled is large, so that the cooling efficiency is higher.

Preferably, the branch pipes are uniformly distributed along the circumferential direction of the annular main pipe. Ensure the uniform cooling effect of the cooling coil pipe.

Preferably, the annular main pipe is provided with a plurality of mounting holes, and the end parts of the branch pipes are inserted into the mounting holes to be welded with the annular main pipe. The annular main pipe and the branch pipe are connected by welding, the sealing performance between the annular main pipe and the branch pipe is good, the connection between the annular main pipe and the branch pipe is firm, and the welding cost is low.

Preferably, the branch pipe is provided with two circles which are respectively positioned on the inner ring of the annular main pipe and the outer ring of the annular main pipe. Further increase the radiation scope of branch pipe, promote cooling efficiency.

Preferably, 15 branch pipes of the annular main pipe inner ring are arranged, and 22 branch pipes of the annular main pipe inner ring are arranged.

Preferably, the pipe diameters of the water inlet pipe and the hand outlet pipe are smaller than those of the annular main pipe, and the water inlet pipe is connected with the annular main pipe and the water outlet pipe is connected with the annular main pipe through reducing bends. The small pipe diameter can increase the flow velocity of the medium in the water inlet pipe and the water outlet pipe, and accelerate the medium to enter and exit.

Preferably, the mounting hole is located in the outer circumference or the inner circumference direction of the annular main pipe. The branch pipe is convenient to install.

Preferably, the annular main pipe connected to the water outlet pipe is arranged above the annular main pipe connected to the water inlet pipe. If the main pipe of the water inlet is arranged above, the medium flow rate of the branch pipe can be accelerated by gravity; the main pipe arrangement of intaking can reduce the velocity of flow in each branch pipe in the below, and the medium can be full of everywhere branch pipe, ensures the cooling effect of everywhere branch pipe unanimously.

The beneficial effects of the utility model are as follows:

1. the spring-shaped branch pipe can increase the radiation range of the cooling coil pipe and improve the cooling efficiency.

2. The utility model has good sealing property by welding the annular main pipe and the branch pipe.

3. According to the utility model, two circles of branch pipes are arranged, so that the radiation range of the branch pipes is further increased, and the cooling efficiency is improved.
