Abstract
Description
Technical Field
[0001] This utility model relates to the field of cryogenic water vapor capture pump technology, specifically a cryogenic water vapor capture pump with low vibration and noise. Background Technology
[0002] A cryogenic water vapor capture pump is a device used to capture water vapor. Its working principle is to utilize a cryogenic surface to rapidly condense water vapor into solid ice, thereby separating the water vapor from the gas. It typically contains a refrigeration system that can cool the capture surface to very low temperatures, such as -100°C or even lower. For example, CN204918757U discloses a novel cryogenic water vapor capture pump, characterized by a five-stage refrigeration assembly, a defrosting assembly, and a buffer assembly. The first port of the five-stage refrigeration assembly is connected to the high-pressure bellows of the compressor via a series-connected water-cooled exchanger and a drying filter. The second port is connected in series via a copper pipe to a refrigeration solenoid valve and a refrigeration manual valve, and circulates to the refrigeration assembly via a loop pipe with a return manual valve. The third port is connected to the low-pressure bellows of the compressor via a copper pipe, forming a first integrated loop. The defrosting assembly forms a second integrated loop, and the buffer assembly forms a third integrated loop. This utility model has a high oil separation efficiency and no adverse effects due to its structural design. It has a simple structure and effectively reduces the probability of oil blockage. However, during use, the pump generates a large vibration amplitude, which causes the pump body to collide with the mounting bracket. This phenomenon not only easily damages the pump body and reduces its lifespan, but also generates noise that seriously affects the working environment of the operators. Therefore, it is urgent to design an ultra-low temperature water vapor capture pump with low vibration and noise to solve the above problems. Utility Model Content
[0003] The purpose of this utility model is to provide a low-vibration and low-noise cryogenic water vapor capture pump to solve the problem mentioned in the background art that the large vibration amplitude generated by the pump during operation leads to the collision between the pump body and the mounting bracket. This phenomenon not only easily damages the pump body and reduces its lifespan, but also generates noise that seriously affects the working environment of the operators.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-vibration and low-noise cryogenic water vapor capture pump, comprising a housing and an outer cover, wherein the outer cover is installed at the top of the housing, a controller is installed on the left side of the front end of the housing, an installation mechanism and a shock-absorbing component are installed inside the housing, the installation mechanism is provided on the front and rear inner walls of the housing, a shock-absorbing component is installed at the bottom of the housing, heat dissipation vents are provided on the front and rear walls of the bottom end of the housing, and an airtight mechanism is installed on the outer side of the left end of the housing.

[0006] Preferably, the mounting mechanism includes a servo motor and a threaded rod. The servo motor is installed on the rear wall inside the housing. The servo motor drives the threaded rod to rotate within the limiting sleeve.

[0010] Preferably, the outer cover includes a sealing plate and sealing strips, and the sealing plate has sealing strips on all four sides of its bottom end. The four sets of sealing strips can be fitted into the top of the U-shaped inner groove.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] This low-vibration and low-noise cryogenic water vapor capture pump improves the sealing between the outer shell and the outer cover by using a U-shaped inner groove inside the outer shell to fit with the sealing strip on the bottom side of the sealing plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-Figure 4 One embodiment provided by this utility model:
[0021] A low-vibration and low-noise cryogenic water vapor capture pump is disclosed in this application. The servo motor 121, air pump 31, and controller 2 used in this application are commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art. The pump includes a housing 1 and an outer cover 4. The outer cover 4 is installed on the top of the housing 1. The pump is characterized in that: the controller 2 is installed on the left side of the front end of the housing 1; the mounting mechanism 12 and the shock-absorbing component 13 are installed inside the housing 1; the mounting mechanism 12 is provided on the front and rear inner walls of the housing 1; the shock-absorbing component 13 is installed at the bottom of the housing 1; heat dissipation vents 14 are opened on the front and rear walls at the bottom of the housing 1; and an airtight mechanism 3 is installed on the outer side of the left end of the housing 1.
[0022] As a further feature of this invention, the top of the outer casing 1 is provided with a spiral groove 11, the inner wall of which is coated with sound-insulating material, and dustproof nets are installed in the center of the two sets of heat dissipation vents 14. This design is beneficial to further reduce noise when the pump inside the casing is working.
[0023] Furthermore, the mounting mechanism 12 includes a servo motor 121 and a threaded rod 122. The servo motor 121 is installed on the inner rear wall of the housing 1. The servo motor 121 drives the threaded rod 122 to rotate within the limiting sleeve 123. A long cylindrical nut 124 is threaded onto the center of the threaded rod 122. The front end of the long cylindrical nut 124 is fixed to the rear center of the fixing plate 125. Two sets of mounting plates 126 are fixed to the top of the fixing plate 125. Sliding blocks 127 are fixed on both the front and rear ends of the fixing plate 125. The centers of the four sets of sliding blocks 127 are all fitted onto the centers of the fixing posts 128. The four sets of fixing posts 128 are installed on the inner wall of the housing 1. This design facilitates the adjustment of the pump body installed on the upper mounting plate of the fixing plate, thereby reducing the contact area between the pump body and the housing and thus reducing noise.
[0024] As a further improvement of this utility model, the shock absorption component 13 includes a base plate 131 and shock-absorbing springs 132. Twelve sets of shock-absorbing springs 132 are installed in the center of the two sets of base plates 131, and a rubber pad 133 is installed at the top of the upper base plate 131, which can better absorb the shock of the pump body and improve its service life.
[0025] As a further feature of this utility model, the airtight mechanism 3 includes an air pump 31 and a fixing block 33. The air pump 31 is installed on the upper side of the fixing block 33, and the fixing block 33 is installed on the left side of the outer shell 1. The air pump 31 is provided with an air pipe 32 that is inserted into the inner groove 11 of the outer shell 1. This design facilitates the vacuum treatment of the inner groove opened in the outer shell, thereby achieving sound insulation.
[0026] Furthermore, the outer cover 4 includes a sealing plate 41 and sealing strips 42. The sealing plate 41 has sealing strips 42 on all four sides at the bottom. The four sets of sealing strips 42 can be fitted into the top of the inner groove 11 to facilitate sealing with the outer shell, which can reduce noise and prevent dust.
[0027] Working principle: In use, the user first powers on the servo motor 121 to drive the threaded rod 122 on the bottom side to rotate within the limiting sleeve 123. The rotation of the threaded rod 122 drives the threaded long cylindrical nut 124 and the fixed plate 125 to rise to the upper side of the outer casing 1. Then, the pump body is installed on the mounting plate (126) at the top of the fixed plate 125. Then, the controller 2 is connected to the pump body, and the servo motor 121 is powered on to drive the threaded rod 122 in reverse to rotate, thereby driving the fixed plate 125 to rise to the upper side of the outer casing 1. The fixed plate 125 and the pump body descend to the top of the shock absorption assembly 13. After the fixed plate 125 descends and presses against the rubber pad 133 bonded to the upper bottom plate 131, the shock absorption spring 132 between the two bottom plates 131 will dampen the vibration. Then, after the sealing strip 42 at the bottom of the sealing plate 41 is fitted into the inner groove 11 at the top of the outer shell 1, the air pump 31 can be started by turning on the power and drawing the gas in the inner groove 11 through the air pipe 32 to form a vacuum environment and thus reduce noise. The above is the complete working principle of this utility model.
[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
