Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge technology, and more specifically to an improved refrigeration system structure for centrifuges. Background Technology
[0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquids and solid particles or liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids with different densities in emulsions (e.g., separating cream from milk); they can also be used to remove liquid from wet solids, such as spinning wet clothes in a washing machine; special high-speed tubular centrifuges can also separate gas mixtures of different densities; taking advantage of the different settling velocities of solid particles of different densities or sizes in liquids, some sedimentation centrifuges can also classify solid particles according to density or particle size.
[0003] Large-capacity refrigerated centrifuges have long suffered from problems such as high noise levels in the refrigeration system and poor cooling performance in the centrifuge chamber. Therefore, a new technical solution is needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide an improved refrigeration system structure for centrifuges, which solves the problems of high noise in the refrigeration system and poor refrigeration effect in the centrifuge chamber that have always existed in large-capacity refrigerated centrifuges.

[0009] In a preferred embodiment of this utility model, a needle valve is fixedly installed on the side of the compressor.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This invention features a machine body with a base plate at its bottom. A refrigeration mechanism with an evaporator is located on top of the base plate. A centrifugal chamber is located inside the machine body, with the evaporator encasing its surface. A refrigeration mechanism mounting plate has a water collection tray on its top.

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.
[0016] Please see Figure 1-2 This utility model provides a technical solution: an improved refrigeration system structure for a centrifuge, comprising: a body 1, a base plate 2 at the bottom of the body 1, a refrigeration mechanism 5 on the upper part of the base plate 2, an evaporator 4 on the upper part of the refrigeration mechanism 5, a centrifuge chamber 3 inside the body 1, the evaporator 4 covering the surface of the centrifuge chamber 3, a mounting plate 11 for the refrigeration mechanism 5, a water receiving tray 14 on the upper part of the mounting plate 11, a compressor 8 on the upper part of the water receiving tray 14, and the compressor 8 being fixedly connected to the water receiving tray 14. The surface of unit 11 is also provided with a condenser 19, a dryer filter 16, a condensate drain valve 12, and a solenoid valve 13. A high-pressure pipe 6, a low-pressure pipe 7, and a capillary tube 17 are provided between the compressor 8, the condenser 19, the dryer filter 16, the condensate drain valve 12, and the solenoid valve 13. The high-pressure pipe 6, the low-pressure pipe 7, and the capillary tube 17 are welded and fixed to the compressor 8, the condenser 19, the dryer filter 16, the condensate drain valve 12, and the solenoid valve 13. A base plate 2 is provided at the bottom of the unit 1, and a refrigeration mechanism 5 is provided on the upper part of the base plate 2. An evaporator 4 is installed on the upper part of the structure 5. A centrifugal chamber 3 is installed inside the body 1, and the evaporator 4 is wrapped around the surface of the centrifugal chamber 3. A refrigeration mechanism 5 is mounted on a mounting plate 11, and a water collection tray 14 is installed on the upper part of the mounting plate 11. A compressor 8 is installed on the upper part of the water collection tray 14, and the compressor 8 is fixedly connected to the water collection tray 14. A condenser 19, a dryer filter 16, a condensate drain valve 12, and a solenoid valve 13 are also installed on the surface of the mounting plate 11. A high-pressure pipe 6 is installed between the compressor 8, the condenser 19, the dryer filter 16, the condensate drain valve 12, and the solenoid valve 13. The low-pressure pipe 7 and capillary tube 17 are welded and fixed to the compressor 8, condenser 19, dryer filter 16, condensate drain valve 12 and solenoid valve 13 respectively. The condenser 19 is enlarged to increase the cooling capacity. The dual-inlet and dual-outlet refrigeration system is adopted to improve the cooling effect. The total power of the dual compressor 8 refrigeration system is reduced and the noise is lower. The two compressors 8 of the dual compressor 8 refrigeration system start at different times, which greatly reduces the noise of the refrigeration system of the large-capacity refrigerated centrifuge. The condensate drain valve 12 can control the discharge of condensate, making the condensate discharge more intelligent.
[0017] Further improvements, such as Figure 2As shown: Two sets of fans 18 are provided on the side of the condenser 19 and the two sets of fans 18 are fixed to the condenser 19 by bolts. The two sets of fans 18 enhance the heat dissipation effect of the condenser 19 and ensure that the condenser 19 can dissipate heat more efficiently, thereby maintaining the stable operation of the refrigeration system.
[0018] Further improvements, such as Figure 2 As shown: A shock-absorbing seat 15 is provided between the compressor 8 and the water receiving tray 14, and the shock-absorbing seat 15 is fixedly connected to the compressor 8 and the water receiving tray 14. The shock-absorbing seat 15 can effectively reduce the vibration generated by the compressor 8 during operation, reduce noise pollution, and protect the compressor 8 and the water receiving tray 14 from damage.
[0019] Further improvements, such as Figure 2 As shown: A starter box 9 is provided on the side of the compressor 8 and the starter box 9 is electrically connected to the compressor 8. The starter box 9 makes the start and control of the compressor 8 more convenient and centralized, making it easier for users to operate and maintain.
[0020] Further improvements, such as Figure 2 As shown: A needle valve 10 is fixedly installed on the side of the compressor 8. The installation of the needle valve 10 makes it possible to precisely adjust the pressure and flow of the refrigeration system, which helps to optimize the refrigeration effect.
[0021] Working Principle: This utility model first installs the condenser 19 on the mounting plate 11, then installs the drip tray 14 on the mounting plate 11. Next, the condensate drain valve 12, solenoid valve 13, and dryer filter 16 are installed on the mounting plate 11. A shock-absorbing seat 15 is installed on the drip tray 14. Then, the compressor 8 is installed and secured with bolts. The high-pressure pipe 6, low-pressure pipe 7, needle valve 10, and capillary tube 17 are welded to their corresponding positions. The compressor 8 starter box 9 is then fixed to the mounting plate 11. Finally, the entire refrigeration unit is installed on the machine base plate 2, secured with bolts, and welded to the evaporator 4, ensuring the sealing of all welds. The assembly is complete. This refrigeration mechanism 5 enlarges the size of the condenser 19, increasing the cooling capacity, and adopts a dual-inlet, dual-outlet refrigeration system, enabling it to… The cooling effect is better; the air volume of the fan 18 is increased, which makes the heat dissipation of the condenser 19 better; the original single-system compressor 8 has a power of 0.HP, and now it is changed to two compressors 8 with a power of 0.HP, which reduces the total power of the compressors 8 in the refrigeration system and makes the noise lower; the two compressors 8 in the dual-compressor refrigeration system start at different times, which greatly reduces the noise of the refrigeration system of the large-capacity refrigerated centrifugal chiller; the condensate drain solenoid valve 13 can control the discharge of condensate, making the condensate draining more intelligent; the original rubber shock absorber of the compressor 8 is changed to a spring shock absorber with better shock absorption effect, which reduces the vibration transmission during the operation of the compressor 8 and makes it quieter.
