Description

Technical Field

[0001] This utility model relates to the field of liquid photosensitive resin storage technology, and in particular to a storage tank for liquid photosensitive resin. Background Technology

[0002] Liquid photosensitive resin is a polymer material that is cured through photochemical reaction under ultraviolet light irradiation. It is mainly composed of oligomers, photoinitiators, and diluents. Its core characteristic is that after the photoinitiator absorbs ultraviolet light of a specific wavelength, it generates active groups, which triggers the cross-linking polymerization of resin molecules to form a stable solid structure.

[0003] Traditionally, because liquid photosensitive resin is sensitive to ultraviolet light, it is generally stored and transported in storage containers made of opaque materials to avoid direct exposure to ultraviolet light that could trigger a pre-curing reaction. The temperature of the liquid photosensitive resin needs to be maintained within a certain range. In some high-temperature areas, it is necessary for personnel to water it to cool it down. However, the cooling effect of the liquid photosensitive resin is not good when it is stored in a storage container, and the manual watering operation is also quite labor-intensive. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a storage tank for liquid photosensitive resin.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a storage tank for liquid photosensitive resin, comprising a tank body, a spacer cylinder disposed inside the tank body, a partition layer formed between the outer wall of the spacer cylinder and the inner wall of the tank body, a storage box for storing cooling liquid disposed outside the tank body, a delivery pump disposed outside the storage box, the input end of the delivery pump communicating with the storage box, the output end of the delivery pump communicating with the partition layer through a flow pipe, and an output pipe communicating with the partition layer disposed at the lower end of the tank body.

[0006] Preferably, the storage box is equipped with a cooling plate.

[0007] Preferably, the output end of the output tube is connected to the interior of the storage box.

[0008] Preferably, a one-way valve is provided on the output pipe.

[0009] Preferably, a flow-dividing ring is fitted on the outer wall of the spacer cylinder, the flow-dividing ring is located inside the spacer layer, and a number of flow ports are opened on the flow-dividing ring along its circumference. The flow pipe is located above the flow-dividing ring at the point where it communicates with the spacer layer.

[0010] Preferably, a temperature detector is installed on the barrel, and the detection end of the temperature detector is inserted into the interior of the barrel.

[0011] The beneficial effects of this utility model are as follows: By setting a partition cylinder inside the barrel, a partition layer is formed between the barrel and the partition cylinder. The cooling liquid is collected by a storage box, and the cooling liquid in the storage box is transported to the partition layer by a delivery pump. Heat exchange occurs between the liquid photosensitive resin inside the barrel through the partition cylinder, keeping the liquid photosensitive resin inside the barrel at a certain temperature. Compared with the prior art, this utility model can cool the liquid photosensitive resin without the need for a partition cylinder, improving the cooling effect of the liquid photosensitive resin and reducing the amount of manual watering. At the same time, by setting an output pipe connected to the inside of the storage box, and setting a cooling plate on the storage box, the cooling liquid after heat exchange in the partition layer can be circulated and cooled, eliminating the need for manual replacement of the heated cooling liquid.

[0022] In this embodiment, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 6 As shown, a storage tank for liquid photosensitive resin includes a tank body 1. A spacer cylinder 2 is disposed inside the tank body 1, concentrically positioned with the tank body 1. The spacer cylinder 2 has a circular design. In this embodiment, the spacer cylinder 2 is made of stainless steel, providing rust prevention and good thermal conductivity. Its upper and lower ends are connected to the upper and lower sides of the inner wall of the tank body 1, respectively. A partition layer 3 is formed between the outer wall of the spacer cylinder 2 and the inner wall of the tank body 1. An L-shaped base (not shown in the attached figure) is disposed below the exterior of the tank body 1. A storage box 4 for storing cooling liquid and a delivery pump 5 are mounted on the base. In this embodiment, the cooling liquid is water. The input end of the delivery pump 5 communicates with the interior of the storage box 4, and the output end of the delivery pump 5 is provided with a flow pipe 6. The output end of the flow pipe 6 communicates with the partition layer 3, and the output end of the flow pipe 6 is located above the tank body 1. The purpose of this is... The cooling liquid flowing out of the flow pipe 6 can flow from top to bottom in the partition 3. An output pipe 7 connected to the partition 3 is provided at the lower end of the barrel 1. The output end of the output pipe 7 is connected to the inside of the storage box 4, and the output end of the output pipe 7 passes through the upper end of the storage box 4. A one-way valve 8 is provided on the output pipe 7. Its purpose is to prevent the cooling liquid in the partition 3 from flowing back into the storage box 4 after passing through the output pipe 7. A cooling plate 12 is provided on the outer wall of the storage box 4. The front side of the cooling plate 12, i.e., its cooling surface, is in contact with the bottom side of the outer wall of the storage box 4. A temperature detector 11 is provided at the bottom of the barrel 1. The detection end of the temperature detector 11 passes into the barrel 1 and is located inside the partition cylinder 2. Its purpose is to detect the temperature of the liquid photosensitive resin inside the barrel 1 so that personnel can intuitively understand the temperature of the liquid photosensitive resin inside the barrel 1.

[0024] A flow divider ring 9 is fitted on the upper outer wall of the spacer cylinder 2. The flow divider ring 9 is located inside the spacer layer 3, and several sets of flow ports 10 are opened on the flow divider ring 9 along its circumference. The flow pipe 6 communicates with the spacer layer 3 above the flow divider ring 9. The purpose is to allow the liquid photosensitive resin flowing out from the flow pipe 6 to pass through the flow ports 10.

[0025] When the temperature of the liquid photosensitive resin inside the barrel 1 is within a suitable range, the delivery pump 5 stops, the cooling chip 12 stops and does not perform cooling, and the detection end of the temperature detector 11 monitors the temperature of the liquid photosensitive resin inside the barrel 1 in real time.

[0026] When the temperature detector 11 detects that the temperature of the liquid photosensitive resin inside the barrel 1 is too high, the personnel control the delivery pump 5 to start working through the control system. The cooling element 12 starts working simultaneously to begin cooling and cool the cooling liquid inside the storage box 4. The delivery pump 5 starts to deliver the cooling liquid in the storage box 4 into the partition 3 through the flow pipe 6, and flows down through the various flow ports 10 on the diversion ring 9. The cooling liquid flows on the outer wall of the partition cylinder 2, reducing the temperature of the partition cylinder 2 and cooling the liquid photosensitive resin inside the barrel 1.

[0027] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
