Description

Technical Field

[0001] The utility model relates to the technical field of cold trap equipment, in particular to a cold trap condensed water capturing device. Background Art

[0002] A cold trap is a device that prevents vapor or liquid from entering a measuring instrument from a system, or from entering a system from a measuring instrument. It can provide a very low temperature surface on which molecules can condense and can increase the vacuum degree by one to two orders of magnitude. However, improper use of cold traps can reduce the accuracy of the instrument, cause damage to the instrument or system, and produce a physical accident. For example, many mixtures of fats used in cold traps are toxic and can cause explosions if not handled properly.

[0003] In the prior art, it is easy for the cold trap to condense water vapor into ice inside during use, and the ice residue will adhere to the condenser, affecting the normal operation of the condenser. However, the existing equipment does not have a structure for cleaning the inside of the cold trap. When ice is found on the condenser, the cold trap can only be stopped and the ice on the condenser can be melted before it can work again. Therefore, this method is not only too slow, but also delays the normal working process.

[0004] Therefore, a cold trap condensed water capturing device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a cold trap condensate capture device, comprising a cold trap body 1, a mounting cavity 2 is provided on the cold trap body 1, an inner liner 3 is movably mounted on the mounting cavity 2; a locking mechanism and a positioning mechanism are mounted on the inner wall of the mounting cavity 2, and the locking mechanism and the positioning mechanism are both mounted on the bottom side of the inner liner 3;

[0025] The locking structure includes a locking block 4, which is mounted on the bottom side of the liner 3, and a movable hole 44 is provided on the locking block 4. A support block 41 is installed on the inner wall of the bottom side of the installation cavity 2, and a connecting rod 42 is installed on the support block 41. A locking platform 45 is installed on the bottom end of the connecting rod 42. The locking platform 45 is slidably installed in the movable hole 44. Two adjustment cavities 47 are provided on the inner wall of the movable hole 44. Trapezoidal blocks 410 are slidably installed in the two adjustment cavities 47. The two trapezoidal blocks 410 are slidably installed in the two adjustment cavities 47. The top sides are in contact with the bottom side of the edge of the locking platform 45. When ice is found on the condenser in the inner liner 3, the cold trap body 1 is immediately stopped, and then the cold trap body 1 is opened to expose the inner liner 3. At this time, it is only necessary to manually press down the inner liner 3 to separate the inner liner 3 from the locking platform 45, take out the frozen inner liner 3, and then re-install another inner liner 3 in the cold trap body 1, so that the cold trap body 1 can work normally without wasting time waiting for the ice on the condenser to melt before working.

[0026] Reference Figure 4In the utility model, a guide rod 48 is slidably installed on the inner wall of the adjusting chamber 47, one end of the guide rod 48 is installed on the trapezoidal block 410, and a locking spring 49 is sleeved on the guide rod 48, one end of the locking spring 49 is installed on the inner wall of the adjusting chamber 47, and the other end of the locking spring 49 is installed on the trapezoidal block 410. By utilizing the restoring force of the locking spring 49, when the inner liner 3 is installed, the trapezoidal block 410 will move backward along the arc surface of the locking platform 45 when it contacts the locking platform 45, and then when it is separated from the arc surface of the locking platform 45, the restoring force of the locking spring 49 can drive the trapezoidal block 410 to move forward, and be clamped at the bottom edge of the locking platform 45 to fix the inner liner 3.

[0027] Reference Figure 3 In the utility model, a transfer platform 43 is sleeved on the connecting rod 42, and a limiting groove 46 is provided on the locking platform 45. The upper end arc surface of the transfer platform 43 is movably installed in the limiting groove 46. The upper end arc surface of the transfer platform 43 is slightly smaller than the lower end arc surface, and the lower end arc surface of the transfer platform 43 is in contact with the trapezoidal block 410. Since the upper arc surface of the transfer platform 43 is slightly smaller than the lower arc surface, when the trapezoidal block 410 drives the transfer platform 43 to move upward, the upper arc surface of the transfer platform 43 can slide into the limiting groove 46 and overlap with it, thereby facilitating the trapezoidal block 410 to slide smoothly from the bottom side arc surface of the transfer platform 43 to the arc surface of the locking platform 45.

[0028] The working principle is as follows: when the cold trap body 1 is in use, if it is found that the condenser in the inner tank 3 is frozen, the cold trap body 1 is stopped immediately, and then the inner tank 3 is pressed downward, so that the locking block 4 at the bottom end of the inner tank 3 moves downward and contacts the upper end surface of the transfer platform 43. When the locking block 4 continues to move downward, after the transfer platform 43 contacts the connecting rod 42, the trapezoidal block 410 will slide from the upper arc surface of the transfer platform 43 to the lower surface of the transfer platform 43 and contact the surface of the connecting rod 42. At the same time, the movement of the locking block 4 drives the trapezoidal block 410 to retract backward, and the trapezoidal block 410 drives the locking spring 49 to be compressed. When the inner liner 3 drives the fixing rod 5 to move downward, the positioning groove 52 in the fixing rod 5 is compressed. When the inner liner 3 is released, the restoring force of the positioning groove 52 can conveniently drive the inner liner 3 to move upward, and the inner liner 3 drives the locking block 4 to move upward. At this time, the trapezoidal block 410 on the locking block 4 drives the transfer platform 43 to move upward, and the upper arc surface of the transfer platform 43 is inserted into the limiting groove 46 on the locking platform 45. At this time, the trapezoidal block 410 slides from the lower arc surface of the transfer platform 43 to the upper arc surface of the locking platform 45, so that the locking block 4 can be conveniently detached from the locking platform 45, and then the inner liner 3 can be conveniently taken out from the cold trap body 1.

[0029] Example 2: Reference Figure 2-3On the basis of Example 1, the positioning mechanism includes a plurality of fixing rods 5, which are all installed on the bottom side of the inner liner 3. A positioning groove 52 is provided on the fixing rod 5, and a return spring 53 is installed on the inner wall of the top side of the positioning groove 52. The other end of the return spring 53 is installed on the top of the plug-in rod 51. The plug-in rod 51 is slidably installed on the inner wall of the positioning groove 52. A plug-in groove 54 is provided on the inner wall of the bottom side of the installation cavity 2. The bottom end of the plug-in rod 51 is movably installed in the plug-in groove 54. When replacing another inner liner 3, it is only necessary to move the inner liner 3 downward to make the plug-in rod 51 is inserted into the insertion slot 54 in the installation cavity 2, and then the inner liner 3 is continuously pressed downward so that the trapezoidal block 410 on the locking block 4 is snapped into the bottom edge of the locking platform 45, so that the inner liner 3 can be conveniently fixed on the cold trap body 1 for use. When the inner liner 3 is replaced, the fixing rod 5 is driven downward by the inner liner 3, and the positioning slot 52 in the fixing rod 5 is compressed. When the inner liner 3 is released, the restoring force of the positioning slot 52 can conveniently drive the inner liner 3 to move upward, thereby facilitating the inner liner 3 to drive the locking block 4 to move upward. The remaining features are the same as those in Example 1.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
