Description

Technical Field

[0001] The utility model relates to the technical field of cold trap equipment, and specifically relates to a cold trap device. Background Technique

[0002] A cold trap is a trap that captures gases by condensation on a cooling surface, usually made of materials such as metal. The general structure of a cold trap device is to place a U-shaped tube in a refrigerant. When a gas passes through the U-shaped tube, substances with higher melting points turn into liquids, and substances with lower melting points pass through the U-shaped tube in gaseous form. Thus, a separation effect can be achieved. Commonly used refrigerants include liquid nitrogen, etc. Usually, the liquid level in a liquid nitrogen cold trap needs to be within a certain height range. If the liquid level is too low, the effect of condensing gases is not good; if the liquid level is too high, not only will the refrigerant overflow, but it may also cause the cold trap passage to freeze and block. Conventional cold traps usually use the method of manual observation and judgment to ensure the liquid level height of the cold trap, which has certain limitations.

[0003] The patent document with the application number 202220343657.8 discloses a cold trap device, including an upper end cover flange, a cold trap inner liner, a cold trap outer shell, a first connection port, a second connection port, a gas discharge passage, and a refrigerant liquid level height control element. A storage cavity for accommodating the refrigerant is provided inside the cold trap inner liner. The upper end cover flange is sealingly connected to the top opening of the cold trap inner liner, and a refrigerant inlet is provided on the upper end cover flange. The cold trap inner liner is sealingly connected inside the cold trap outer shell. The gas discharge passage and the refrigerant liquid level height control element of the utility model can effectively control the liquid level height, thereby avoiding the problems of refrigerant overflow and possible freezing and blockage of the cold trap passage caused by too high a liquid level. Moreover, the liquid level height does not require manual observation and judgment, and the operation is simple and convenient.

[0004] The cold trap device disclosed in the above document has the following defects: When the device cools and processes a liquid, the liquid needs to enter and be discharged through the cold trap inner liner. When the temperature is too low, part of the liquid solidifies and remains on the inner wall of the inner liner. To ensure the cooling effect, the inner wall of this device needs to be cleaned. This structure is not convenient for cleaning the cold trap inner liner, reducing the flexibility of the device.

[0005] It can be seen from this that the existing cooling device does not have the function of conveniently cleaning the inner liner, and it is necessary to improve the existing deficiencies to provide a function that can conveniently clean the inner liner of the device. Content of the Utility Model

[0006] The purpose of the utility model is to provide a cold trap device to solve at least to some extent the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a cold trap device, which includes a refrigeration structure and a sealing structure. The sealing structure is installed on the outer walls on both sides of the refrigeration structure. The refrigeration structure includes a housing. Baffles are installed on the outer walls on both sides of the housing. A transfer pipe is installed on the side of the two baffles that are close to each other. A fixing frame is installed on one side of the housing. A sealing door is rotatably connected to one side of the fixing frame. Two fixing clips are welded to the side of the fixing frame away from the sealing door. A clamping rod is rotatably connected to the inner walls of the two fixing clips. The sealing door is combined on the inner wall of the fixing frame. Two limit blocks are arranged on the side of the sealing door close to the clamping rod. The clamping rod is clamped in the inner walls of the limit blocks. The purpose of such a setting is that during the use of the device, rotate the rotating plate upwards, the opening of the inclined surface frame is exposed, pour the liquid into the thin nozzle of the transfer pipe, the top feed pipe is connected to the refrigeration component, the refrigeration material flows down through the feed pipe into the refrigeration pipe, and the bottom feed pipe is used to discharge the consumed refrigeration material. The isolation pipe keeps the internal temperature insulated. The baffle isolates the isolation pipe from the outside, improving the refrigeration effect of the inner tank of the device. A plurality of refrigeration pipes transmit cold air to the outer wall of the transfer pipe, and the internal liquid is refrigerated through the transfer pipe. A discharge pipe is connected to the hole of the sealing door, and the liquid finally discharges outwards through the other end of the transfer pipe and the discharge pipe. When it is necessary to clean the inner wall of the transfer pipe, rotate the two clamping rods outwards, the limit blocks release the restriction on the clamping rods, and then rotate the sealing door outwards to expose the opening of the fixing frame and the port of the transfer pipe. Without disassembling the device, the inner wall of the transfer pipe can be cleaned, improving the flexibility of the device.

[0009] Further, an isolation pipe is arranged on the side of the two baffles that are close to each other, and the transfer pipe is located inside the isolation pipe. The purpose of such a setting is that during the use of the device, the isolation pipe keeps the internal temperature insulated, and the baffle isolates the isolation pipe from the outside, improving the refrigeration effect of the inner tank of the device.

[0010] Further, a plurality of refrigeration pipes are arranged outside the isolation pipe close to the transfer pipe, and both ends of the plurality of refrigeration pipes are installed on the outer walls of the two baffles. The purpose of such a setting is that during the use of the device, the plurality of refrigeration pipes transmit cold air to the outer wall of the transfer pipe, and the internal liquid is refrigerated through the transfer pipe.

[0011] Further, three feed pipes are arranged at the top of the isolation pipe, and one feed pipe is arranged at the bottom on one side of the isolation pipe. The four feed pipes penetrate through the isolation pipe and extend to the outside of the housing. The purpose of such a setting is that during the use of the device, the top feed pipe is connected to the refrigeration component, and the refrigeration material flows down through the feed pipe into the refrigeration pipe, and the bottom feed pipe is used to discharge the consumed refrigeration material.

[0012] Furthermore, on the other side of the housing, there is an inclined surface frame, and on the upper surface of the inclined surface frame, there are fixing blocks. The purpose of this setting is that during the use of the device, due to the design of the inclined surface frame, the rotating plate coincides with the inclined surface frame downward by inertia, making one side of the device in a closed state.

[0013] Furthermore, a rotating plate is rotatably connected to the outer wall of the fixing block, and the rotating plate covers the opening of the inclined surface frame. The purpose of this setting is that during the use of the device, when the rotating plate is rotated upward, the opening of the inclined surface frame is exposed, and liquid can be poured in through the thin nozzle of the transfer pipe.

[0014] The utility model has the following beneficial effects:

[0015] Through the setting of the transfer pipe and the clamping rods, the internal liquid is processed by refrigeration through the transfer pipe, and the drain pipe is connected to the hole of the sealing door. Finally, the liquid is discharged outward through the other end of the transfer pipe and the drain pipe. When it is necessary to clean the inner wall of the transfer pipe, the two clamping rods are rotated outward, and the limiting block releases the restriction on the clamping rods. Then, the sealing door is rotated outward to expose the opening of the fixed frame and the port of the transfer pipe. Without disassembling the device, the inner wall of the transfer pipe can be cleaned, improving the flexibility of the device.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
