Description

Technical Field

[0001] This utility model belongs to the field of phosphogypsum crushing and grinding technology, and specifically relates to a phosphogypsum crushing and grinding device. Background Technology

[0002] Phosphogypsum crushing and grinding equipment is a type of equipment used to crush and grind solid waste generated in the wet phosphoric acid process. The crushed phosphogypsum can be applied in agriculture, industry, construction engineering, and waste gas mine landfill.

[0003] Existing phosphogypsum crushing and grinding devices mainly consist of a casing, crushing rollers, and grinding rollers. In practical applications, the crushing and grinding rollers are driven by an electric motor to crush and grind the phosphogypsum. Although these phosphogypsum crushing and grinding devices can crush and grind phosphogypsum, most of them can only crush and grind phosphogypsum once. They cannot screen or re-crush and grind the crushed and ground phosphogypsum as needed, resulting in poor practical application effect of the phosphogypsum crushing and grinding devices.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a phosphogypsum pulverizing and grinding device that can solve the above problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 7 As shown, the phosphogypsum crushing and grinding device in one embodiment of the present invention includes: a crusher shell 1, a discharge pipe 101, a screening and grinding component 2, and a vibration anti-blocking component 3.

[0033] like Figures 1 to 3 As shown, a discharge pipe 101 is fixedly connected to the lower part of the crusher housing 1. The crushed phosphogypsum fragments inside the crusher housing 1 are discharged through the discharge pipe 101.

[0034] like Figure 1 As shown, a pair of crushing rollers 102 are rotatably connected inside the crusher housing 1, and the pair of crushing rollers 102 rotate in opposite directions. The phosphogypsum to be processed can be crushed by the pair of crushing rollers 102 rotating in opposite directions.

[0035] like Figure 1As shown, multiple sets of evenly distributed grinding cones 103 are rotatably assembled inside the discharge pipe 101. Grinding sleeves 104 are fitted onto the outer sides of the multiple sets of grinding cones 103, and the grinding sleeves 104 are fixedly connected to the inner wall of the discharge pipe 101. The pulverized phosphogypsum is ground and processed by the cooperation of the multiple sets of grinding cones 103 and grinding sleeves 104.

[0036] like Figures 1 to 2 As shown, the screening and grinding assembly 2 is mounted below the discharge pipe 101. The screening and grinding assembly 2 includes a guide pipe 201, which is fixedly mounted below the discharge pipe 101. The guide pipe 201 guides and conveys the phosphogypsum material discharged from the discharge pipe 101.

[0037] like Figure 1 As shown, a feed pipe 205 is fixedly connected to the lower part of the guide pipe 201. The feed pipe 205 is arranged below the arc-shaped sieve grinding screen 202 and is connected to the guide pipe 201. The feed pipe 205 discharges the phosphogypsum that meets the size requirements sieved by the arc-shaped sieve grinding screen 202 through the feed pipe 205.

[0038] like Figures 1 to 2 As shown, an arc-shaped screening and grinding mesh 202 is fixedly connected inside the guide pipe 201, and the arc-shaped screening and grinding mesh 202 is fixedly connected to the inner wall of the guide pipe 201. The phosphogypsum material discharged from the guide pipe 201 is screened by the arc-shaped screening and grinding mesh 202.

[0039] Specifically, the arc-shaped screening and grinding mesh 202 and the grinding cylinder 203 cooperate to form a crushing and grinding gap. The larger phosphogypsum is further crushed and ground through the grinding gap.

[0040] like Figures 1 to 2 As shown, a guide cylinder 204 is fixedly connected above the arc-shaped screening and grinding mesh 202, and the guide cylinder 204 is in communication with the grinding sleeve 104.

The drive cam 303 is fitted onto one end of the drive shaft 206 located outside the guide tube 201. The drive cam 303 is configured to cooperate with the extrusion drive plate 302. By controlling the rotation of the drive cam 303, the extrusion top plate 305 is subjected to rotary reciprocating extrusion.

[0047] like Figures 3 to 6 As shown, guide rods 304 are fixedly connected inside the extrusion drive plate 302. The movement of the guide rods 304 is controlled to synchronously move the extrusion drive plate 302, thus facilitating the up-and-down movement control of the dust-removing rod 301. An extrusion top plate 305 is fixedly connected above the guide rods 304, and the extrusion top plate 305 is correspondingly positioned to correspond with the drive cam 303. The extrusion top plate 305 ensures the contact stability between the drive cam 303 and the extrusion top plate 305.

[0048] like Figures 3 to 6 As shown, a limiting base plate 306 is inserted and assembled below the guide rod 304, and the limiting base plate 306 is fixedly assembled on the side wall of the guide pipe 201. The limiting base plate 306 serves to limit the assembly and guide the sliding of the guide rod 304.

[0049] like Figures 3 to 6As shown, a limiting spring 307 is provided between the extrusion drive plate 302 and the limiting base plate 306, and the limiting spring 307 is fitted on the outside of the guide rod 304. The extrusion drive plate 302 is supported and limited by the contraction and reset of the limiting spring 307.

[0050] In practical use, the phosphogypsum material to be processed can be crushed by a pair of crushing rollers 102 rotating in opposite directions. The crushed phosphogypsum material can be conveyed into the discharge pipe 101 and ground under the combined action of the grinding sleeve 104 and multiple sets of grinding cones 103.

[0051] The ground phosphogypsum material can be guided along the feed cylinder 204 into the arc-shaped screening and grinding screen 202. The phosphogypsum material is screened by the arc-shaped screening and grinding screen 202. The screened phosphogypsum material can be output along the feed pipe 205. The phosphogypsum material that fails to pass the screening can be further crushed and ground by the rotating grinding cylinder 203 and the fixed arc-shaped screening and grinding screen 202. The phosphogypsum material that passes the grinding can be discharged along the feed pipe 205.
