Description

Technical Field

[0002] When the spiral freezer is working, only the inlet and outlet holes are connected to the outside world to allow goods to enter and exit, but there is also a certain amount of heat exchange. Due to the influence of the airflow inside the warehouse, the wind pressure on the inside of the inlet and outlet is unbalanced, and hot air will blow into the freezer from one of them, and cold air will blow out from the other, thus forming cold air leakage. Cold air leakage will cause energy waste and pose a safety hazard, which will cause personal injury to the operators who spiral in and out goods. The purpose of installing an air curtain on the spiral freezer is to reduce the leakage of cold air at the inlet and outlet. The principle of the air curtain is to use the wind blown out by the air curtain fan to block the blowing of hot air from the outside of the warehouse or reduce the blowing of cold air from the inside of the warehouse.

A first limiting hole 8 is opened on one side of the moving frame 5, and a threaded column 11 is movably sleeved on the inner circular wall surface of the first limiting hole 8, and the threaded column 11 is fixedly installed with one end of the driving shaft of the driving mechanism 6. A brush plate 9 is movably sleeved inside the moving frame 5, and there are bristles at the bottom of the brush plate 9. Rectangular grooves are respectively opened on both sides of the inside of the moving frame 5, and the rectangular grooves are movably sleeved with the brush plate 9. A threaded hole 10 is opened on one side of the brush plate 9, and the threaded hole 10 is threadedly connected to the threaded column 11. A first handle 13 is fixedly installed on one side of the moving frame 5.

[0026] By means of the spiral freezer body 1, when the user is using the spiral freezer body 1, the cold air inside the spiral freezer body 1 will overflow through the conveyor belts of the feed port, and then through the support frame 2, which is installed near the feed port, the fan 14 is started, so that the fan 14 draws the air from the top of the fixed cover 3 into the interior and blows it into the interior of the support frame 2, and then the dust in the air is filtered through the filter screen 12, and the wind blown into the interior of the support frame 2 forms a wind curtain through the plurality of wind guide louvers 25, thereby preventing the cold air from flowing out of the support frame 2.

In addition, after long-term use, the filter Dust may accumulate on the top surface of the filter 12, which may reduce the air intake per unit time, resulting in insufficient wind force of the air curtain. Then, the driving mechanism 6 is set and the driving mechanism 6 is started to drive the threaded column 11 to rotate, so that the threaded hole 10 and the threaded column 11 convert the rotational motion into a linear motion. At the same time, the rectangular groove inside the movable frame 5 limits the brush plate 9, and the brush plate 9 drives the brush at the bottom to brush and clean the dust on the top surface of the filter 12. After cleaning, the user holds the filter 12 and pulls the movable frame 5 out of the first fixing hole 4 to clean the dust. The dust is poured out for cleaning, and then the installation and reset can be performed, and the timing can be performed through the set PLC controller, for example, the drive mechanism 6 is started once every 72 hours to drive the brush plate 9 to clean once, so that the filter 12 is always kept unobstructed, thereby comprehensively achieving the effect of cleaning the dust on the top surface of the filter 12, so that it can be cleaned at fixed intervals to keep the air inlet of the filter 12 unobstructed and avoid affecting the air volume of the wind curtain. Moreover, through the set drive motor 22, rotating mechanism 23 and air guide louver 25, the angle of the air guide louver 25 can be electrically adjusted, eliminating manual operation and facilitating use.
