TECHNICAL FIELD

[0001] The utility model relates to the field of water vapor trapping pump oil distributor, especially relates to a super low temperature water vapor trapping pump oil distributor. BACKGROUND

[0002] In the field of modern industrial production and scientific research experiment, the super low temperature water vapor trapping pump plays a vital role. In the process of semiconductor manufacturing, in order to ensure the high purity of production environment, it is necessary to remove the water vapor in the process gas by using the super low temperature water vapor trapping pump. In the freeze-drying experiment of biological samples, the super low temperature water vapor trapping pump can effectively trap the sublimated water vapor, and ensure the smooth progress of the experiment. The oil distributor, as a key component of the super low temperature water vapor trapping pump, plays an indispensable role in the stable operation and performance optimization of the equipment. It can separate the oil-gas mixture generated during the operation of the trapping pump, prevent oil pollution of the system, ensure efficient operation of the trapping pump and maintain the stability of the entire production or experimental process.

[0003] The existing super low temperature water vapor trapping pump oil distributor has many problems in practical application. In the installation of the oil distributor, the traditional installation method is usually simple, and only relies on a few bolts for fixation, lacking effective anti-loosening measures. When the super low temperature water vapor trapping pump is running, the equipment will vibrate, and long-term vibration will cause the bolts to gradually loosen. For example, in some precision manufacturing workshops with extremely high requirements for equipment stability, loosening of the oil distributor will lead to a decrease in oil-gas separation effect, and then the water vapor trapping pump will mix with oil inside, affecting the trapping efficiency, and even possibly damaging the precision components inside the equipment. In the maintenance of the heat dissipation filter plate, the heat dissipation filter plate of the traditional super low temperature water vapor trapping pump oil distributor is complicated to disassemble and install. Usually, multiple tools are needed to disassemble multiple complex components to remove the heat dissipation filter plate. For example, when cleaning the dust and impurities accumulated on the heat dissipation filter plate, the operator often cannot clean it in time due to the inconvenience of disassembly, resulting in blockage of the heat dissipation filter plate and affecting the heat dissipation effect of the trapping pump. Poor heat dissipation will cause the temperature inside the trapping pump to rise, reducing the performance and service life of the equipment. Moreover, the complex disassembly process will also prolong the downtime of the equipment and reduce the work efficiency.

[0004] To this end, the present application proposes a super low temperature water vapor trapping pump oil distributor to solve the above technical problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] With reference to Figure 1 and Figure 2 An embodiment provided by the present application: a kind of ultra-low temperature water vapor trapping pump oil distributor, including trapping pump body 1, trapping pump body 1 front side middle end is provided with oil distributor body 2, three fixed mounting plates 3 are fixedly connected to the outer wall of oil distributor body 2, fixed mounting plate 3 is connected with trapping pump body 1 by limiting screw rod 4, the bottom end of the rear side of trapping pump body 1 is slidably connected with heat dissipation filter plate 7, the left and right sides of heat dissipation filter plate 7 are fixedly connected with fixed limiting strip 8, the bottom end of the left and right sides of trapping pump body 1 is fixedly connected with fixed mounting block 5, fixed mounting block 5 is connected with fixed limiting strip 8 by limiting adjusting rod 10. The outer wall of limiting screw rod 4 penetrates the inside of fixed mounting plate 3, one end of limiting spring 15 is connected with the inside of limiting screw rod 4, the other end is connected with the front side of abutting disc 16. Two preset limiting strips 11 are fixedly connected to the outer wall of limiting adjusting rod 10, two preset limiting blocks 12 are fixedly connected to the right end of limiting adjusting rod 10, preset limiting ring 6 is provided with preset through slot 13 at the top end and the bottom end in the inside, and preset half through slot 14 is formed in the left and right ends in the inside of preset limiting ring 6. The outer wall of preset limiting strip 11 is slidably connected to the inner wall of fixed limiting strip 8, and the outer wall of preset limiting block 12 is slidably connected to the inner wall of 13. The rear side of adjusting screw cap 9 is rotatably connected to the front side of fixed mounting block 5.

[0025] Specifically, in the use of a kind of ultra-low temperature water vapor trapping pump oil distributor, installation oil distributor body 2 is one of key steps.Starting installation, operator needs to carefully align the preset installation hole of fixed mounting plate 3 on the outer wall of oil distributor body 2 with the installation hole reserved in front of trapping pump body 1, after alignment, limit screw rod 4 is carefully installed into two installation holes as a whole.After the rotation of limit screw rod 4, it will move linearly in horizontal direction smoothly under the action of threaded connection.In the operation process, the operator should pay attention to the movement of limit screw rod 4 at all times, when it moves to the limit position, rotation and movement should be stopped immediately.In operation, attention should be paid to the strength of rotating adjusting screw cap 9, avoid damaging the thread or other components due to excessive force.With the movement of limit adjusting rod 10, the preset limit block 12 at the rear end will gradually separate from the preset clamping position of the preset through slot 14 opened on the preset limit ring 6.When preset limit block 12 completely separates from preset through slot 14, preset limit ring 6 can be rotated.At this time, the operator needs to carefully rotate preset limit ring 6, align 13 opened inside preset limit ring 6 with preset limit block 12 accurately, then preset limit ring 6 can be removed smoothly, and the quick disassembly of heat dissipation filter plate 7 is realized.After cleaning or maintenance, heat dissipation filter plate 7 can be reinstalled according to the reverse steps, to ensure that the trapping pump can run continuously and stably.

[0026] With reference to Figure 4 Fixed mounting plate 3 is connected with limit screw rod 4 at front side by threaded connection, abutting disc 16 is connected with limit screw rod 4 at rear end by sliding connection, limit spring 15 is arranged at rear side of fixed mounting plate 3;

[0027] Specifically, the reaction force generated by limit spring 15 provides stable support force to abutting disc 16 and limit screw rod 4 inside, which makes the connection of limit screw rod 4 with fixed mounting plate 3 and trapping pump body 1 more closely, effectively enhances the installation structure stability of oil distributor body 2, ensures that oil distributor body 2 will not appear loose phenomenon during equipment operation, and guarantees the normal operation of trapping pump.

[0028] With reference to Figure 3 Limit adjusting rod 10 is connected with two fixed limit strips 8 inside by sliding connection, adjusting screw cap 9 is connected with limit adjusting rod 10 at front end by threaded connection, preset limit ring 6 is connected with limit adjusting rod 10 at rear end by sliding connection;

[0029] Specifically, when the inside of the trapping pump body 1 needs to be cleaned or daily maintenance and repair work is carried out, the quick disassembly design of the heat dissipation filter plate 7 arranged at the rear side of the trapping pump body 1 is particularly important. When disassembling, the operator first needs to find the adjusting screw cap 9, which is usually located near the fixed mounting block 5 and is relatively easy to identify. Then, the operator needs to hold the adjusting screw cap 9 and rotate it slowly and evenly. During rotation, due to the threaded connection and the limiting effect of the internal shape of the fixed limiting strip 8, the limiting adjusting rod 10 will move linearly inside the fixed mounting block 5 and the fixed limiting strip 8 as a whole.

[0030] Working principle: When the operator installs the oil distributor body 2 on the outer wall of the trapping pump body 1, first align the preset mounting hole of the fixed mounting plate 3 on the outer wall of the oil distributor body 2 with the mounting hole reserved on the front side of the trapping pump body 1, then install the limiting screw rod 4 into the two mounting holes as a whole, and under the threaded connection, the limiting screw rod 4 will move linearly in the horizontal direction during rotation, and stop rotating and moving when the limiting screw rod 4 moves to the limit position. During movement, the abutting disc 16 at the rear side of the limiting screw rod 4 will continuously contact the mounting hole reserved on the front side of the trapping pump body 1. After installation is completed, under the reaction force of the limiting spring 15 arranged inside the limiting screw rod 4, the limiting spring 15 will provide support to the abutting disc 16 and the inside of the limiting screw rod 4, making the limiting screw rod 4 more closely connected with the fixed mounting plate 3 and the trapping pump body 1, thereby enhancing the installation structure stability of the oil distributor body 2.

[0031] If the inside of the trapping pump body 1 needs to be cleaned or daily maintenance and repair is required, the heat dissipation filter plate 7 arranged at the rear side of the trapping pump body 1 can be quickly disassembled through the mounting mechanism on both sides. The operator can rotate the adjusting screw cap 9, and under the threaded connection and the limiting effect of the internal shape of the fixed limiting strip 8, the limiting adjusting rod 10 will move linearly inside the fixed mounting block 5 and the fixed limiting strip 8 as a whole, so that the preset limiting block 12 at the rear end of the limiting adjusting rod 10 is separated from the preset clamping position of the preset through slot 14 opened on the preset limiting ring 6, so that the preset limiting ring 6 can be rotated, aligning the 13 inside the preset limiting ring 6 with the preset limiting block 12 to remove the preset limiting ring 6, thereby achieving quick disassembly of the heat dissipation filter plate 7.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
