Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration tanks, and more specifically to a refrigeration and heat preservation tank. Background Art
[0002] When storing raw milk, in order to facilitate the storage of raw milk, milk storage tanks are used to store the raw milk. According to national standards, raw milk needs to be stored in an environment of 1°C-4°C. During storage, the raw milk needs to be sampled and tested regularly, and indicators such as microorganisms and acidity need to be tested and recorded to ensure the quality of the raw milk. However, most of the current milk storage tanks are directly used in insulation tanks, and the coolant is spread around the insulation tank to cool the insulation tank and then store the raw milk inside the milk storage tank. Although the refrigeration effect is good, the coolant surrounding the insulation tank will cause excessive cooling, so that part of the coolant cannot play a cooling effect, resulting in a waste of coolant, increasing energy loss and milk storage costs. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a refrigeration and heat preservation tank to solve the problems existing in the above-mentioned background technology.
[0004] The utility model provides the following technical scheme: a refrigeration and heat preservation tank, comprising an outer protective shell, an inlet pipe is arranged on the top of the outer protective shell, an outlet pipe is arranged on the bottom of the outer protective shell, a delivery pipe is arranged on the outer side of the outer protective shell, a refrigeration device is arranged on one end of the delivery pipe, a heat preservation liner is arranged inside the outer protective shell, receiving plates are arranged on the upper and lower sides of the heat preservation liner, a cooling pipe is arranged on the outer side of the heat preservation liner, a polyurethane heat preservation layer is arranged inside the outer protective shell, a fan assembly is arranged on one side of the refrigeration device, and the coolant is shunted through the cooling pipe, so as to quantitatively control the coolant outside the heat preservation liner, and prevent the internal coolant from cooling and lowering the temperature outside the heat preservation liner, thereby avoiding excessive coolant, which cannot fully play a cooling effect and causes waste, thereby improving the utilization rate and cooling effect of the coolant and reducing the storage cost of milk;
[0005] Furthermore, the number of the cooling tubes is at least eighteen, and the eighteen cooling tubes are equidistantly installed around the outside of the thermal insulation liner. The outside of the thermal insulation liner is cooled and cooled simultaneously by multiple cooling tubes, thereby evenly cooling the thermal insulation liner, thereby increasing the cooling effect of the coolant.
[0006] Furthermore, a water inlet is provided at the top of the inlet pipe, and a cooling ring located inside the thermal insulation liner is provided at one end of the water inlet. The milk inside the thermal insulation liner is cooled by the cooling ring, thereby improving the cooling effect of the milk.
[0007] Furthermore, a polyester fiber insulation layer located outside the insulation liner is provided between the cooling tubes. The polyester fiber insulation layer separates the multiple cooling tubes to prevent mutual interference between the cooling tubes, thereby causing the cooling liquid to be unable to fully play a cooling effect and causing energy waste.
[0008] Furthermore, the diameter of the cooling ring is two-fifths of the diameter of the heat-insulating inner liner, so that the temperature of the milk inside the cooling ring is almost the same as the temperature of the milk outside the cooling ring, thereby avoiding uneven cooling of the raw milk.
[0009] Compared with the prior art, the beneficial effect of the present invention is that the outer side of the thermal insulation liner is cooled and lowered by a plurality of cooling tubes at the same time, and the plurality of cooling tubes are separated by a polyester fiber thermal insulation layer to avoid excessive coolant that cannot fully play a cooling effect and thus cause waste, thereby increasing the utilization rate of the coolant and reducing the storage cost of milk. At the same time, part of the coolant will flow along the cooling ring inside the thermal insulation liner to cool the inside of the milk, thereby improving the cooling effect of the milk and avoiding uneven cooling of the raw milk.

DETAILED DESCRIPTION
[0014] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The refrigeration and heat preservation tank involved in the present invention is not limited to the various structures recorded in the following embodiments.

[0015] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0016] Embodiment 1
[0017] Reference Figure 1-3 , a refrigeration and heat preservation tank, first install the receiving plate 9 on both ends of the heat preservation inner tank 8, then install the water inlet 12 inside the receiving plate 9, then install the cooling ring 13 inside the heat preservation inner tank 8, and connect the two ends of the cooling ring 13 with the water inlet 12, then install the cooling pipe 11 around the outside of the heat preservation inner tank 8, then install the polyurethane heat preservation layer 7 on the inside of the outer protective shell 1, then install the heat preservation inner tank 8 inside the outer protective shell 1, then fill the polyester fiber heat preservation layer 10 between the cooling pipe 11, between the heat preservation inner tank 8 and the polyurethane heat preservation layer 7, then install the inlet pipe 2 on the top of the outer protective shell 1, then install the outlet pipe 3 on the bottom of the outer protective shell 1, then install the fan assembly 6 on one side of the refrigeration device 5, and then connect the refrigeration devices 5 to each other through the conveying pipe 4. It is particularly noted that the diameter of the cooling ring 13 is three-fifths of the diameter of the heat preservation inner tank 8.
[0018] The working principle of the utility model is as follows: the staff transfers the raw milk to the heat preservation inner tank 8 through the inlet pipe 2. When the heat preservation inner tank 8 is full, the refrigeration device 5 and the fan assembly 6 are started to start cooling, and then the coolant is transported to the water inlet 12 through the delivery pipe 4. At this time, the coolant at the water inlet 12 flows to the inside of the receiving plate 9 and starts to be divided. Most of the coolant enters the cooling pipes 11 around the receiving plate 9 to cool the outside of the heat preservation inner tank 8, thereby performing interval cooling and cooling on the outside of the heat preservation inner tank 8. At the same time, the polyester fiber insulation layer 10 between the cooling pipes 11 separates them to prevent the coolant from being too hot. The cooling liquid in the cooling tube 11 and the cooling ring 13 eventually flows to the water inlet 12 at the bottom of the outer protective shell 1 and enters the refrigeration device 5 through the delivery pipe 4 for re-refrigeration; at the same time, the polyurethane insulation layer 7, the insulation liner 8, and the polyester fiber insulation layer 10 perform triple insulation to prevent the cooling liquid temperature from rising and becoming unusable.
[0019] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
