Description

Technical Field

[0001] This utility model relates to the field of precooling machine technology, and in particular to an environmentally friendly and safe nitrogen precooling unit. Background Technology

[0002] Air precooling units are compressed air purification equipment that uses the principle of refrigeration to forcibly cool compressed air based on the relationship between the saturated vapor pressure and temperature of water. This causes the water vapor in the compressed air to become supersaturated at low temperatures, condense and dew, and separate the water. Air precooling units are professional products designed and developed specifically for the oxygen and nitrogen production processes in the air separation industry, which require low air dew points and air outlet temperatures of around 5-8℃.

[0003] Chinese patent document CN202320124714.8 discloses a pre-cooling machine with rapid feeding. The key technical points are: a vacuum pre-cooling machine body with a placement plate inside and a baffle plate on the top surface of the placement plate; and a feeding assembly disposed on the bottom surface of the vacuum pre-cooling machine body for rapid feeding of food. The feeding assembly includes two chutes, both of which are formed on the bottom surface of the vacuum pre-cooling machine body. Two sliders are fixedly installed on the bottom surface of the placement plate. The vacuum pre-cooling machine body, placement plate, baffle plate, chutes, sliders, connecting holes, limiting blocks, operating plate, connecting column, limiting groove, mounting groove, spring, limiting column, and fixing holes work together to facilitate rapid feeding of the vacuum pre-cooling machine body and prevent the interior of the vacuum pre-cooling machine body from being too deep, making it difficult for workers to place food into the deep interior.

[0004] However, the above-mentioned patent has certain defects in use. The precooler is equipped with casters at the bottom to facilitate the movement of the precooler. However, during daily use, the internal compressor will vibrate due to continuous operation. The precooler needs to be placed on a flat surface to prevent resonance and displacement.

[0005] Therefore, an environmentally friendly and safe nitrogen precooling unit is proposed here to solve the above-mentioned problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 4As shown, an environmentally friendly and safe nitrogen precooling unit includes a precooling machine body with a precooling system inside for cooling incoming gas. The top of the precooling machine body has an inlet pipe 4 and an outlet pipe 5, which are connected to the interior of the precooling machine body. The inlet pipe 4 is used for high-temperature air to enter, and the outlet pipe 5 is used for low-temperature air to exit. The inlet pipe 4 and the outlet pipe 5 form a closed airflow circulation system with the interior of the precooling machine. High-temperature air enters through the inlet pipe 4, is precooled, and then exits through the outlet pipe 5. The bottom of the precooling machine body has a receiving cavity 81, and a moving device 8 is installed inside the receiving cavity 81. The moving device 8 includes a motor 6, a threaded rod 61, a sliding rod 84, a sliding sleeve 85, and a hinge seat.

[0027] The motor 6 is fixed on the outer wall of the precooler body. The threaded rod 61 is set at the output end of the motor 6. The threaded rod 61 extends into the receiving cavity 81 and abuts against the inner wall of the receiving cavity 81. The two ends of the threaded rod 61 are provided with threads, which are symmetrical and opposite. Two sliding sleeves 85 are provided. The sliding sleeves 85 are respectively set at the two ends of the threaded rod 61 and are threadedly connected to the rotating shaft.

[0028] The hinge base includes a first hinge base 83 and a second hinge base 86. The first hinge base 83 is fixed to the lower end of the sliding sleeve 85. A support rod 87 is hinged to the first hinge base 83. The second hinge base 86 is located at the end of the support rod 87. A support plate 82 is provided at the lower end of the second hinge base 86. Four casters 9 are provided at the bottom of the support plate 82 and fixed to the four top corners of the support plate 82. The casters 9 are provided to enable flexible movement.

[0029] The moving device 8 also includes a slide rod 84, which is arranged parallel to the threaded rod 61. The slide rod 84 is used to increase the stability of the movement of the sliding sleeve 85. The slide rod 84 is fixed on the inner wall of the receiving cavity 81. Two sliding sleeves 85 are symmetrically arranged on the slide rod 84. The sliding sleeves 85 are sleeved on the slide rod 84. A first hinge seat 83 is fixed on the lower surface of the sliding sleeve 85. A support rod 87 is hinged on the first hinge seat 83. A second hinge seat 86 is arranged at the end of the support rod 87. The lower end of the second hinge seat 86 is fixed to the upper surface of the support plate 82.

[0030] The moving device 8 is set up so that when the motor 6 starts, it drives the threaded rod 61 to rotate. Since the two ends of the threaded rod 61 have threads in opposite directions, when the threaded rod 61 rotates, the two sliding sleeves 85 will move in opposite directions at the same time. The sliding sleeves 85 are connected to the support rod 87 through the hinge seat. The other end of the support rod 87 is connected to the support plate 82. As the sliding sleeves 85 move, the support plate 82 also rises and falls accordingly, so that the moving device 8 can rise and fall freely. When it needs to be moved, the moving device 8 is extended to move. When it needs to be stationary, the moving device 8 is retracted so that the bottom of the precooling machine body contacts the ground to ensure its stability.

[0031] The precooling machine body is equipped with shock-absorbing pads 7 at its bottom. There are four shock-absorbing pads 7, which are fixed around the bottom of the precooling machine body. The shock-absorbing pads 7 are provided with multiple anti-slip grooves 71. The shock-absorbing pads 7 are made of highly elastic material. When the equipment is subjected to vibration or impact, the shock-absorbing pads 7 can absorb some of the energy and convert and dissipate it, thereby reducing the direct impact and damage to the equipment. The anti-slip grooves 71 at the bottom of the shock-absorbing pads 7 increase the friction with the ground and further improve its stability.

[0032] The precooling machine body has four guide pillars 11 around its top. The outer peripheral wall of the guide pillars 11 is provided with external threads. The precooling machine body is provided with a top cover 2. The guide pillars 11 pass through the top cover 2. The top cover 2 is fixedly connected to the precooling machine body by nuts 3. The top cover 2 and the precooling machine body are detachably connected to facilitate internal installation and maintenance.

[0033] The front of the precooling machine body is provided with an electrical maintenance door 12 and a display control screen 13. The electrical maintenance door 12 facilitates daily maintenance and troubleshooting. The display control screen 13 is fixed in the upper right corner of the front of the precooling machine body. Multiple pressure gauges are also provided on the left side of the display control screen 13. The display controller can be used to display the equipment operating status and parameters, and has control functions. The pressure gauges monitor the pressure changes in real time during the precooling process to ensure operational safety.

[0034] The precooling machine body has symmetrical heat dissipation grilles 14 on its left and right side walls. The heat dissipation grilles 14 form air convection, effectively dissipating the heat generated by the equipment operation, improving heat dissipation efficiency, and extending the service life of the equipment.

[0035] The working principle of this utility model is as follows: When it is necessary to move the main body of the precooling machine, the motor 6 is started. The motor 6 drives the threaded rod 61 to rotate, and the sliding sleeve 85 on the threaded rod 61 also moves in the opposite direction. The sliding sleeve 85 is connected to the support rod 87 through the hinge seat. The other end of the support rod 87 is connected to the support plate 82. As the sliding sleeve 85 moves, the support plate 82 also rises and falls until the universal wheel 9 at the bottom of the support plate 82 touches the ground. Finally, the universal wheel 9 is used to make the equipment move flexibly to the required position.

[0036] When the device needs to be moved to a designated location and left to stand, the motor 6 is started to rotate in the opposite direction, retracting the support plate 82 into the receiving cavity 81, so that the bottom of the precooling machine body contacts the ground, ensuring the stability of the body and realizing convenient movement and stable placement of the equipment.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
