Embodiment 1

[0035] Embodiment 1, with reference to figure 1 , 2 As shown, the present invention provides a hand-held dry ice filler, comprising: a filling bucket 1 , a heat exchanger 2 disposed in the filling bucket 1 and a handle 3 fixedly connected to the filling bucket 1 .

[0036] optional, see figure 1 , 2 As shown, the heat exchanger 2 is fixedly connected to the filling barrel 1 by fastening bolts. The handle 3 has a support rod extending axially and radially along the filling barrel 1, which is convenient for the user to lift and hold. The support rod is fixed to the filling bucket 1 through a support plate. Optionally, the support plate is welded to the filling bucket 1 . The support plate has an arc-shaped arm, and the axially and radially extending support rods are respectively arranged at two ends of the arc-shaped arm.

[0037] The filling barrel 1 is provided with a liquid inlet pipe 11 and a spray port 12, and the liquid inlet pipe 11 is used for connecting high-pressu...

Abstract

The invention provides a handheld dry ice filling device. The handheld dry ice filling device comprises a filling bucket, a heat exchanger arranged in the filling bucket and a handle fixedly connectedto the filling bucket; the filling bucket is provided with a liquid inlet pipeline and a jetting opening, a throttling channel and multiple cooling and heat-exchange channels are axially formed in the heat exchanger, the cooling and heat-exchange channels are sequentially connected end to end, the cooling and heat-exchange channel in the head end is communicated with the liquid inlet pipeline, and the cooling and heat-exchange channel in the tail end is communicated with the throttling channel; an outlet of the throttling channel is communicated with the jetting opening, the throttling channel is internally provided with a throttling device, and liquid carbon dioxide enters the cooling and heat-exchange channels via the liquid inlet pipeline, and is jetted out from the jetting opening after flowing through the throttling channel to be converted into dry ice. The handheld dry ice filling device is convenient to use, the cost is reduced, and the coolant filling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerant filling, in particular to a hand-held dry ice filler. Background technique [0002] At present, the existing cold chain logistics technology has a low degree of automation, mainly through manual handling of solid packaged dry ice blocks, so as to achieve the effect of keeping cold chain goods refrigerated and insulated. Due to the extremely low temperature of packaged dry ice, skin frostbite is very easy to occur during the handling process Another method is to use a solid-state ice machine, but the solid-state ice machine is bulky and expensive, and is not suitable for small cold chain logistics companies. Therefore, research and development of a small and convenient refrigerant filler has great significance. practical significance. Contents of the invention [0003] The invention provides a hand-held dry ice filling device, aiming to improve the problems of low automation, large volume an...
