Problems solved by technology

[0002] The storage and transportation of raw materials for chemical product production plants are mainly transported by train or automobile tanker. Some raw materials with high freezing points will freeze in the tanker during transportation. Especially in the cold winter in the north, the material will freeze, causing Tank truck unloading is very difficult
[0003] The traditional thawing method is to use steam to heat the frozen material outside the tank car. Not only the thawing time is long, the labor intensity is high, the operation efficiency is low, but also the steam consumption is large, the unloading cost increases, and the water accumulation outside the tank car Ice affects the on-site operating environment and poses certain safety hazards
[0004] Therefore, there are above-mentioned inconveniences and problems in the known railway, road transport tank car or tank car material thawing mode

Embodiment 1

[0029] The rapid thawing device for rail and road transport tank cars or tank car materials of the present invention includes a return crane pipe, an unloading crane pipe, an unloading pump and a heater.

[0030] see now figure 1 , figure 1 It is a schematic diagram of material melting cycle formed by the rapid thawing device of the embodiment of the present invention. As shown in the figure, one end of the return crane pipe 2 and one end of the unloading crane pipe 3 are inserted into the tank car port or the tank car port of the railway or road transport tank car or tank car, and directly inserted into the frozen material in the tank car or tank car; The other end of the return crane pipe is connected to the heater outlet 5 of the heater 6 through the return pipe 4; the other end of the unloading crane pipe 3 is connected to one end of the unloading pump 8 through the unloading pipe 12, and the other end of the unloading pump 8 is connected through a tee respectively. It i...

Embodiment 2

[0033] The method for rapid thawing of materials in tank cars transported by railways and roads is characterized in that it comprises the following steps:

[0034] a. Insert the unloading crane tube and the return crane tube into the roof opening of the tank car respectively, and make the lower end of the unloading crane tube located in the unfrozen liquid material in the middle of the tank car;

[0035] b. Start the unloading pump, pump the liquid material in the tank car to the heater through the unloading crane pipe and the unloading pipe, and return to the tank car through the return pipe and the return crane pipe after being heated by steam;

[0036] c. The reflowed heated material returned to the tank car through the return pipe and the return crane pipe is mixed with the frozen material in the tank car, and the frozen material is gradually melted;

[0037] d. Repeat steps b and c, and continue to circulate until the frozen material in the tank car is completely melted; ...

Embodiment 3

[0040] In this embodiment, except that a tank car is used instead of a tank car, the others are the same as in Embodiment 2, wherein the unloading crane pipe and the return crane pipe are respectively inserted into the top port of the tank car.

[0041] The present invention has substantive features and significant technical progress. The device and method for rapid thawing of materials in railway and road transport tank cars or tank cars is different from traditional railway and road methods that use steam to heat outside the tank car to thaw frozen materials. Compared with the thawing method of transporting tank car or tank car materials, a heater, return crane pipe, return pipe and steam pipe are added; the return crane pipe is connected to the outlet of the heater through the return pipe, and the unloading crane pipe is connected through the unloading pipe, unloading pump and valve At the inlet end of the heater, the heater is respectively connected with a condensed water d...

Abstract

The invention discloses a railway and highway transport tank car material fast unfreezing device. The device comprises a return crane pipe, an unloading crane pipe, an unloading pump and a heater, and is characterized in that one end of the return crane pipe (2) and one end of the unloading crane pipe (3) are together inserted into a tank car port of a railway and highway transport tank car, and the other end of the return crane pipe is connected with a heater outlet (5) of the heater (6) through a return pipe (4); and the other end of the unloading crane pipe (3) is connected with one end of the unloading pump (8) through an unloading pipe (12), wherein a heating supply unit is provided, heating supply steam enters the heater through a steam inlet (10), and steam condensate is discharged out of the heater through a steam condensate discharging outlet. The railway and highway transport tank car material fast unfreezing device has the advantages that the structure is simple, use is convenient, the personnel and vehicle equipment operation efficiency is improved, the labor intensity is relieved, the unfreezing and unloading time is shortened, the steam consumption is effectively reduced, and the unloading cost is lowered.
