[0030] In this embodiment, the material enters the second circulation pipe 400 from the feeding port, then enters the tank body 1 through the second circulation pipe 400, and is heated by steam, and then enters the evaporation tank 500 through the first circulation pipe 200. After a certain number of cycles, the material is discharged through the outlet.

[0031] See also Figure 2 The utility model provides a vacuum salt-making heating device 100, comprising a tank body 1, a heating tube 2 and an anti-blocking component, wherein the tank body 1 is provided with a feed port and a discharge port at two opposite ends; the heating tube 2 is extended along the length direction of the tank body 1, the heating tube 2 is installed in the tank body 1 and the two ends are correspondingly connected to the feed port and the discharge port, a heating chamber 14 is enclosed between the heating tube 2 and the tank body 1, and the heating chamber 14 is used for passing steam; the anti-blocking component is arranged at the feed port, and the anti-blocking component is used to break the salt blocks entering the heating tube.

[0032] In this embodiment, a feed port and a discharge port are provided at opposite ends of the tank body 1; the heating tube 2 is extended along the length direction of the tank body 1, the heating tube 2 is installed in the tank body 1 and the two ends are correspondingly connected to the feed port and the discharge port, a heating chamber 14 is enclosed between the heating tube 2 and the tank body 1, and the heating chamber 14 is used to pass steam, and the anti-blocking component is arranged at the feed port.

The anti-blocking component can crush the salt block and reduce the volume of the salt block, so that the salt block can pass through the heating tube 2 smoothly, avoiding the salt block from clogging the heating tube 2, thereby solving the problem of clogging the heating tube 2.

[0033] The anti-blocking component has various specific forms:

[0034] In one of the embodiments, the anti-blocking component includes a filter element 3, and the filter element 3 is transversely arranged at the feed inlet. The filter element 3 is penetrated by a plurality of filter holes, and the plurality of filter holes are arranged at intervals.

[0035] In this embodiment, the filter element 3 is made of a hard material, and a plurality of filter holes are arranged on the filter element 3, so that the filter element 3 is hollowed out to form a filter mesh structure. When the salt blocks pass through the filter element 3, the salt blocks smaller than the filter holes can directly pass through the filter holes, while the salt blocks larger than the filter holes continuously collide with the filter element 3 under the push of the circulation pump 300, so that the salt blocks are broken into small-volume salt blocks passing through the filter holes. By setting the filter element 3, large salt blocks can be broken to avoid pipe blockage.

[0036] In another embodiment, the anti-blocking component includes a rotating shaft, a plurality of crushing blades and a driving component. The rotating shaft is rotatably installed in the tank body 1 along the length direction of the tank body 1 and is close to the feed port. The plurality of crushing blades are arranged at intervals along the circumference of the rotating shaft on the outer periphery of the rotating shaft, and the crushing blades are fixedly connected to the rotating shaft. The driving component is connected to the rotating shaft to drive the rotating shaft to rotate. The rotating shaft is driven to rotate by the driving component, and the rotating shaft drives the plurality of crushing blades to rotate, thereby crushing the salt blocks through the crushing blades to prevent the salt blocks from clogging the heating tube 2.

[0037] In one embodiment, the side length of the filter hole is L, the diameter of the heating tube 2 is R, and L= R.

[0038] The specific form of the filter hole is not limited, and it can be a square hole, a round hole, or a hole of other shapes. In the present embodiment, the filter hole is a square hole, and the side length of the square hole is two-thirds of the diameter of the heating tube 2. With such a configuration, the salt block entering the heating tube 2 through filtering through the filter hole is much smaller than the diameter of the heating tube 2, thereby avoiding blockage of the tube.

[0039] In one embodiment, a plurality of the heating tubes 2 are provided, and the plurality of the heating tubes 2 are arranged at intervals.

[0040] In this embodiment, in order to improve the heating efficiency, a plurality of heating tubes 2 are provided, and the vacuum salt making heating device 100 also includes two mounting plates 4, and the two mounting plates 4 are arranged in the tank body 1 at intervals along the vertical direction, and the mounting plates 4 are adapted to the tank body 1, and the mounting plates 4 are sealed and connected to the inner wall of the tank body 1, and the heating tube 2 is passed through the two mounting plates 4, and the tank body 1, the mounting plates 4 and the heating tube 2 are jointly enclosed to form the heating chamber 14, and the tank body 1 is also provided with a steam port and a condensate outlet connected to the heating chamber 14, and the steam enters the heating chamber 14 from the steam inlet and exchanges heat with the material in the heating tube 2, thereby heating the material, and the steam is condensed into condensate after heat exchange and discharged from the condensate outlet.

[0041] In one embodiment, the total cross-sectional area of ​​the plurality of filter holes is S1, the total cross-sectional area of ​​the plurality of heating tubes 2 is S2, and S1>3S2.

[0042] In this embodiment, in order to avoid increasing pipeline pressure, the total cross-sectional area of ​​the filter holes is more than three times the total cross-sectional area of ​​the plurality of heating tubes 2. Such a setting can reduce the obstruction of the filter element 3 to the material and avoid increasing pipeline resistance and causing the current of the circulation pump 300 to increase.

[0043] In one embodiment, the filter element 3 is configured in a conical shape and gradually decreases toward the feed inlet.

[0044] In this embodiment, since the total cross-sectional area of ​​the filter holes is more than three times the total cross-sectional area of ​​the plurality of heating tubes 2, the filter element 3 as a whole is in a conical cylindrical structure. This arrangement increases the surface area of ​​the filter element 3, and more filter holes can be arranged, thereby increasing the cross-sectional area of ​​the filter holes.

[0045] In one embodiment, the filter element 3 is detachably connected to the tank body 1 .

[0046] In one embodiment, the tank body 1 includes a first section 11, a second section 12 and a third section 13 which are detachably connected from top to bottom, the discharge port is located in the first section 11, the feed port is located at the lower end of the third section 13, and the heating tube 2 is located in the second section 12.

The bending portion is arranged between the flanges of the second section 12 and the third section 13, and the filter element 3 is also installed while installing and connecting the second section 12 and the third section 13, so as to facilitate assembly and later maintenance of the filter element 3.

[0049] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0050] The material enters the second circulation pipe 400 from the feeding port, and then enters the tank body 1 through the second circulation pipe 400. The salt block passes through the filter element 3 before entering the heating tube 2. The salt block smaller than the filter hole can directly pass through the filter hole, while the salt block larger than the filter hole continuously hits the filter element 3 under the push of the circulation pump 300, so that the salt block is broken into small-volume salt blocks that pass through the filter hole and enter the heating tube 2. Subsequently, the material temperature is increased by heat exchange with the steam in the heating chamber 14, and then enters the evaporation tank 500 through the first circulation pipe 200. After a certain number of cycles, the material is discharged through the outlet.
