Description

Technical Field

[0001] This utility model relates to the field of desulfurized gypsum technology, and in particular to a spraying device for reducing the chloride ion content in desulfurized gypsum. Background Technology

[0002] Desulfurization gypsum is a byproduct of flue gas desulfurization in coal / oil-fired industries. Its main component is calcium sulfate dihydrate, and it is an industrial solid waste that can be utilized as a resource.

[0003] Most existing gypsum dewatering methods use vacuum belt dewatering machines, which are high-efficiency dewatering devices that use vacuum adsorption and belt drive to achieve solid-liquid separation. However, traditional vacuum belt dewatering machines only complete solid-liquid separation, and chloride ions can easily accumulate, resulting in a high chloride ion content in the gypsum filter cake after pressure filtration. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spraying device that reduces the chloride ion content in desulfurized gypsum.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spraying device for reducing chloride ion content in desulfurized gypsum includes a vacuum belt dewatering machine body and a limiting component. Fixed legs are fixedly installed at both ends of the vacuum belt dewatering machine body, and movable legs are slidably sleeved on the upper ends of the fixed legs. The tops of the two movable legs are connected by a top plate.

[0007] A water tank is installed on the top of the top plate. Both ends of the water tank are connected to the output end via solenoid valves, and several spray heads are installed on the other end of the connecting pipe.

[0008] Furthermore, a preferred configuration is that a filter pipe is installed at the inlet of the water tank.

[0009] In addition, a preferred structure is that an electric push rod is fixedly installed in the groove of the fixed leg, and the telescopic end of the electric push rod is fixedly connected to the top of the movable leg.

[0010] In addition, a preferred structure is that sliding grooves are provided on both sides of the inner wall of the movable leg, and four sliding holes are provided on one side of the movable leg.

[0011] In addition, a preferred structure is that a scale is provided on one side of the fixed leg, and sliders are provided on both sides of the upper end of the fixed leg, with the sliders sliding within the groove.

[0012] In addition, a preferred structure is that several limiting grooves are provided on one side of the fixed support leg.

[0013] In addition, a preferred structure is that the limiting component includes a connecting pull plate, and four limiting pins are installed on one side of the connecting pull plate through four connecting posts. The connecting posts slide through the sliding holes, and the limiting pins are inserted into the limiting grooves.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, a spraying device is added to the main body of the vacuum belt dewatering machine. The water sprayed from the spray head penetrates into the gypsum filter cake, dissolves and carries away free chloride ions, thereby reducing the chloride ion content in the gypsum filter cake.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7A spraying device for reducing chloride ion content in desulfurized gypsum includes a vacuum belt dewatering machine body 1 and a limiting component 7. Fixed support legs 2 are fixedly installed at both ends of the vacuum belt dewatering machine body 1. Movable support legs 3 are slidably sleeved on the upper end of the fixed support legs 2. The tops of the two movable support legs 3 are connected by a top plate 4.

[0026] Among them, a water tank 5 is installed on the top of the top plate 4, and the output ends of the water tank 5 are connected to the connecting pipe 11 through the solenoid valve 9. Several spray heads 8 are installed on the other end of the connecting pipe 11.

[0027] Meanwhile, a filter pipe 6 is installed at the inlet of water tank 5. The filter pipe 6 filters the water entering water tank 5 to prevent clogging of the spray head 8.

[0028] Furthermore, an electric push rod 10 is fixedly installed in the groove of the fixed support leg 2. The telescopic end of the electric push rod 10 is fixedly connected to the top of the movable support leg 3. The spray height can be adjusted by extending or retracting the electric push rod 10.

[0029] Meanwhile, sliding grooves 31 are provided on both sides of the inner wall of the movable leg 3, and four sliding holes 32 are provided on one side of the movable leg 3.

[0030] Furthermore, a scale 21 is provided on one side of the fixed support leg 2, and sliders 22 are provided on both sides of the upper end of the fixed support leg 2. The sliders 22 slide within the slide groove 31. When adjusting the spray height, the movable support leg 3 moves. By observing the position of the scale 21 at the lower end of the movable support leg 3, the spray height can be determined.

[0031] Meanwhile, several limiting grooves 23 are opened on one side of the fixed support leg 2. The limiting component 7 includes a connecting pull plate 71. Four limiting pins 73 are installed on one side of the connecting pull plate 71 through four connecting posts 72. The connecting posts 72 slide through the sliding holes 32, and the limiting pins 73 are inserted into the limiting grooves 23. The limiting pins 73 and the electric push rod 10 jointly bear the downward pressure generated by the movable support leg 3, thereby protecting the electric push rod 10.

[0032] In this embodiment, gypsum is pressed and filtered into gypsum filter cake on the main body 1 of the vacuum belt dewatering machine and conveyed on the conveyor belt. At this time, the solenoid valve 9 and the spray head 8 are opened, and the spray head 8 sprays water to penetrate into the gypsum filter cake, remove chloride ions in the gypsum filter cake, thereby reducing the chloride ion content in the gypsum filter cake, so that the gypsum meets the industry standards.

[0033] Simultaneously, the spray height of the spray head 8 can be adjusted according to the thickness of the gypsum filter cake. The two electric push rods 10 are activated to move slightly upwards synchronously, pushing the movable support leg 3 to move slightly. At this time, the limit pin 73 is not under pressure. The connecting plate 71 is pulled to move the limit pin 73 from the limit groove 23 into the sliding hole 32. Then, the electric push rod 10 is activated to move the movable support leg 3 upwards or downwards. Observe the scale 21 at the lower end of the movable support leg 3. When the movable support leg 3 moves to the predetermined position, the sliding hole 32 aligns with the limit groove 23, the electric push rod 10 stops working, and the connecting plate 71 is pushed to insert the limit pin 73 into the limit groove 23. At this time, the downward pressure generated by the movable support leg 3 is borne jointly by the electric push rod 10 and the limit pin 73, thus protecting the electric push rod 10. The spray height of the spray head 8 can then be adjusted, effectively reducing the chloride ion content in gypsum filter cakes of different thicknesses.

[0034] In this invention, a spraying device is added to the main body 1 of the vacuum belt dewatering machine. The spray head 8 sprays water that penetrates into the gypsum filter cake, dissolves and carries away free chloride ions, thereby reducing the chloride ion content in the gypsum filter cake.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
