Description

Technical Field

[0001] The utility model relates to the technical field of caustic soda flake conveying equipment, in particular to a caustic soda flake spiral conveying device for a workshop. Background Art

[0002] When adding caustic soda flakes into the reactor, they are generally put into the feeding hopper and then transported to the reactor through the spiral conveyor. Since caustic soda flakes have the characteristic of absorbing moisture, the caustic soda flakes will absorb moisture during transportation, storage in the warehouse, and the process of opening bags, weighing and feeding at the production site (which takes a certain amount of time to complete). The caustic soda flakes that absorb moisture are easy to stick to the inner wall of the spiral conveyor cavity. As time goes by, more and more caustic soda flakes accumulate on the inner wall, affecting transportation and making cleaning difficult.

[0003] Therefore, we designed a screw conveying device for caustic soda flakes in workshops. Utility Model Content

[0027] Embodiment 1, in combination with the attached Figure 1-4 A screw conveying device for caustic soda flakes in a workshop comprises a screw conveying device body 1, a feeding hopper 2 is arranged above the feeding port of the screw conveying device body 1, a valve 3 is arranged at the discharge port of the feeding hopper 2, and the discharge port of the valve 3 is correspondingly connected with the feeding port of the screw conveying device body 1; the feeding port of the feeding hopper 2 is provided with a sealing cover plate 21 which can be opened and closed;

[0028] As required, a sealing gasket is provided between the sealing cover plate 21 and the feed opening of the feeding hopper 2 so that the sealing cover plate 21 and the feed opening of the feeding hopper 2 are sealed and matched.

[0029] As required, the sealing cover plate 21 can be connected to the feed port of the hopper 2 in a hinged manner; further, the upper plate surface of the sealing cover plate 21 has a handle for opening and closing the sealing cover plate 21.

[0030] It also includes a heating system 4 for heating the caustic soda flakes in the hopper 2;

[0031] Furthermore, the heating system 4 adopts a heating structure that can uniformly heat the wall of the hopper 2. For example, the heating system 4 is a graphene heating film covering the hopper 2 and a controller that controls the heating temperature of the graphene heating film, that is, the graphene heating film can be controlled to be powered on and off by the controller so as to achieve the function of controlling the temperature inside the hopper 2; for another example, the wall of the hopper 2 has a hollow interlayer 22; the heating system 4 includes a steam inlet pipe 41 and a steam outlet pipe 42 connected to the hollow interlayer 22, that is, the wall of the hopper 2 is heated by introducing hot steam into the hollow interlayer 22, so as to achieve the heating of the temperature inside the hopper 2.

[0032] The vacuum pump 5 is used to extract the gas in the hopper 2 so that the hopper 2 is in a negative pressure environment.

[0033] It should be noted that: there is no specific limitation on the installation position of the vacuum pump 5 , and it is only necessary to ensure that the gas in the hopper 2 can be extracted so that the hopper 2 is in a negative pressure environment.

[0034] When in use, first add a certain amount of flake caustic soda into the feeding hopper 2, then heat the feeding hopper 2 through the heating system 4, so that the flake caustic soda is in a "high temperature" environment, and then start the vacuum pump 5 to extract the gas in the feeding hopper 2 so that the feeding hopper 2 is in a negative pressure environment. At this time, the flake caustic soda is dried in a "high temperature" and negative pressure environment. At this time, when passing through the screw conveyor body 1, the flake caustic soda will not stick to the inner wall of the cavity of the screw conveyor body 1, thereby effectively solving the problem of difficulty in conveying flake caustic soda by the screw conveyor body 1.

[0035] It should be noted that the screw conveyor body 1 is installed and fixed according to actual needs. Since the installation and fixing of the screw conveyor body 1 is an existing conventional technology, it will not be described in detail here.

[0036] As required, the feeding hopper 2 can be fixedly mounted on the screw conveying device body 1; it can also be installed through a separate support frame 8.

[0037] When the hopper 2 is installed through a separate support frame 8, since the screw conveyor body 1 may vibrate during operation, in order to prevent a connection failure between the feed port of the screw conveyor body 1 and the discharge port of the hopper 2; preferably, the discharge port of the valve 3 is connected to the feed port of the screw conveyor body 1 through a flexible material pipe 9. At this time, the hopper 2.

[0039] Combined with Figure 3 The top of the support frame 8 has a supporting portion 81 that supports both sides of the bottom of the cylinder 22 , and an elastic connecting member 82 is provided between the supporting surface of the supporting portion 81 and the side wall of the cylinder 22 .

[0040] Embodiment 3, in combination with the attached Figure 1-2 A screw conveying device for caustic soda flakes in a workshop is provided. Based on the second embodiment, the device is used to better dry the caustic soda flakes in a "high temperature" and negative pressure environment. The device also includes a structure that can fluidize the caustic soda flakes in the feeding hopper 2 so that the caustic soda flakes are heated evenly.

[0041] For example, in conjunction with Figure 1 The structure is as follows: a vibration device 10, which is arranged at the bottom of a cylinder 22, so as to cause the feeding hopper 2 to vibrate, so that the caustic soda flakes in the feeding hopper 2 are in a fluidized state; for example, in combination with the attached Figure 2 , 4 The structure is as follows: a stirring device 11 is coaxially arranged on a cylinder 22 to stir the caustic soda flakes in the hopper 2 so that the caustic soda flakes are in a fluidized state. Specifically, a stirring rod of the stirring device 11 is coaxially arranged on an inner cavity of the cylinder 22. Since the stirring device 11 is conventional technology, its structure is not described in detail here.

[0042] Embodiment 4, in combination with the attached Figure 1-4 A workshop caustic soda screw conveying device, based on any one of embodiments one to three, is designed to quickly cool down the dry caustic soda in the feeding hopper 2; preferably, the heating system 4 includes a steam inlet pipe 41 and a steam outlet pipe 42 connected to the hollow interlayer 22.

[0043] In this embodiment, the hopper 2 is also provided with a cooling water inlet pipe 6 and a cooling water outlet pipe 7 communicated with the hollow interlayer 22. In this way, the temperature of the hopper 2 and the dried caustic soda flakes in the hopper 2 can be quickly reduced by the flowing cooling water.

[0044] It should be noted that the specific positions of the cooling water inlet pipe 6 and the cooling water outlet pipe 7 are set according to the actual shape of the hopper 2. No specific position limitation is made at this time. It only needs to ensure that after cooling is completed, the cooling water in the hollow interlayer 22 can be almost completely discharged.
