A multi-mode caustic soda flake product cooling device

Abstract

The invention discloses a multi-mode cooling device for caustic soda flake products, and relates to the cooling of high-temperature solid industrial products, in particular to the field of deep cooling of caustic soda flake products. The device comprises a feed port (1), a water-cooled tube shell (2, 9), a feed pipe (3), a feed screw rod (4), a drive motor (5), a motor belt (6), a nitrogen inlet (7), a nitrogen outlet (10), an observation hole (8, 11), a star-shaped discharger (12), a discharge port (13), a cooling water inlet (17, 15), a cooling water outlet (14, 16), and a temperature digital display panel (18, 19). The nitrogen used in the device passes through the inside of the feed pipe (3), and the cooling water flows through the water-cooled tube shell (2, 9). Through the multi-mode cooling of nitrogen + water cooling, the high-temperature caustic soda flake product is deeply cooled, effectively solving the problems of high-temperature caustic soda flake transportation agglomeration and easy hot bags, and reducing the packaging cost of the caustic soda flake product. In addition, the feeding process of the device is carried out in a closed and nitrogen-protected manner, which greatly reduces the degree of deterioration of the caustic soda flake product and can effectively improve the quality standard of the caustic soda flake product.

Description

Technical Field

[0001] The invention relates to cooling of high-temperature solid industrial products, in particular to a multi-mode cooling device for caustic soda flake products. Background Art

[0002] Caustic soda flakes are a very important industrial raw material. The caustic soda flakes produced by the caustic soda frying method are characterized by high temperature and easy adhesion. They are easy to deteriorate when exposed to air, which makes it difficult to control product quality and easy to burn the packaging bags. The existing technology uses roller spray cooling, but the roller cooling efficiency is low and the sealing is poor. Summary of the invention

[0003] In order to overcome the defects of the prior art, the present invention provides a multi-mode caustic soda flake product cooling device. The device adopts nitrogen + water cooling multi-mode cooling and screw rod feeding to achieve deep cooling and anti-sticking of high-temperature caustic soda flakes.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is as follows: the device includes a feed inlet, a water-cooled tube shell, a feed pipeline, a feed screw rod, a drive motor, a motor belt, a nitrogen inlet and outlet, an observation hole, a star-shaped unloader, a discharge port, a cooling water inlet and outlet, and a temperature digital display panel.

[0005] The conveying pipeline is provided with a conveying screw rod inside, connected by bearing frames 19 and 22, and provided with a two-stage water-cooled shell outside; the front section is provided with a feed port, and the rear section is provided with a discharge port; a star-shaped discharger is installed at the discharge port; the conveying pipeline is also provided with a temperature digital display panel and an observation hole; the observation hole is made of high-pressure glass inside. Nitrogen passes through the conveying pipeline and directly contacts the product for cooling and protection, and cooling water circulates in the water-cooled shell outside the conveying pipeline to cool the internal caustic soda product through heat exchange.

[0006] The two ends of the feeding screw rod are provided with bearing frames 19 and 22, and the screw rod is evenly welded with threaded sheets 20, which is driven to rotate by a driving motor.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] (1) Through nitrogen + water cooling multi-mode cooling, high-temperature caustic soda flakes are deeply cooled, effectively reducing the temperature of caustic soda flakes, solving problems such as easy-to-burn bags and high packaging costs;

[0009] (2) The feeding adopts a spiral rod with controllable speed, which can prevent the product from sticking by rotating;

[0010] (3) The feeding process is carried out in a closed and nitrogen-protected environment, which greatly reduces the degree of deterioration of the caustic soda flakes and can effectively improve the quality of the caustic soda flakes. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The flake caustic soda product enters the conveying pipeline 3 from the feed inlet 1, is transported to the end of the conveying pipeline 3 through the conveying screw rod 4, is discharged through the star-shaped discharger 12, and is sent out for packaging from the discharge port 13.

[0019] Furthermore, the feed pipeline 3 is cooled by nitrogen and water cooling. Nitrogen enters the feed pipeline 3 through the nitrogen inlet 7, directly cools the product inside and is discharged from the outlet 10. Water-cooled tube shells 2 and 9 are provided outside the feed pipeline 3. Cooling water enters the water-cooled tube shells through the water inlets 15 and 17, cools the product inside the feed pipeline through heat exchange, and then flows out through the water outlets 14 and 16.

[0020] Furthermore, the feed pipe 3 is provided with temperature digital display panels 17, 18 and observation holes 8, 11, which can monitor the product temperature and bonding conditions in real time.

[0021] Furthermore, the feeding screw rod 4 is driven by the driving motor 5 , and the two are connected by a belt, and the product is transported to the discharge port 13 under the drive of the screw rod.
