Description

Technical Field

[0001] This utility model relates to the technical field of ammonium chloride recovery equipment, and in particular to a vibrating screen device for recovering ammonium chloride crystals. Background Technology

[0002] In the recovery of ammonium chloride, the solution typically contains small amounts of insoluble impurities such as dust, silt, and metal particles. These impurities have different particle sizes than the ammonium chloride crystals and are usually removed using a vibrating screen. During the screening process, pure ammonium chloride crystals of suitable size pass through as "undersize," while most large, insoluble impurities are intercepted and removed as "oversize," effectively improving the purity of the recovered ammonium chloride crystals. Currently, the impurity removal of ammonium chloride crystals typically involves multiple vibrating screens connected end-to-end for staged screening, as described in the screening system technical solution disclosed in Chinese Utility Model Patent Application Publication No. CN201848385U. However, gaps usually exist between adjacent vibrating screens, allowing ammonium chloride crystals to easily spill out. Therefore, we propose a vibrating screen device for recovering ammonium chloride crystals. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vibrating screen device for recovering ammonium chloride crystals.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a vibrating screen device for recovering ammonium chloride crystals, comprising at least two sets of vibrating screens, wherein the discharge port of the primary vibrating screen is connected to the inlet port of the secondary vibrating screen, the height of the primary vibrating screen is higher than that of the secondary vibrating screen, a guide is provided at the discharge port of the primary vibrating screen, and a receiving component is provided at the inlet port of the secondary vibrating screen, the guide is provided with a first roller shutter portion, the first roller shutter portion is suspended below the edge of the guide, and the receiving component is provided with a second roller shutter portion, the second roller shutter portion is located above the edge portion of the receiving component, and the first roller shutter portion and the second roller shutter portion are wound around each other.

[0005] To further elaborate, the guide member has wing plate portions on both sides for connecting with the side plates of the primary vibrating screen, and the receiving member has a receiving plate portion. The distance between the two wing plate portions of the guide member is less than the width of the receiving plate portion.

[0006] To elaborate further, the primary vibrating screen includes a screening box, a transmission mechanism, and a drive motor. A deflection shaft is provided at the screening box, and the deflection shaft is poweredly connected to the drive motor through the transmission mechanism.

[0007] To elaborate further, the screening box is provided with floating mechanisms on both sides, and the floating mechanisms include a first spring group and a second spring group, which are respectively located on both sides of the deflection shaft.

[0008] To elaborate further, the upper end of the first spring assembly is connected to the screen box, and the lower end of the first spring assembly is connected to the support at the bottom of the screen box.

[0009] To elaborate further, the structure of the secondary vibrating screen is the same as that of the primary vibrating screen.

[0010] The beneficial effects of this utility model are as follows: the guide component of the primary vibrating screen and the receiving component of the secondary vibrating screen are connected to each other, and the first roller section of the guide component and the second roller section of the receiving component are rolled together. When a certain relative movement occurs between the primary vibrating screen and the secondary vibrating screen, the first roller section and the second roller section that are rolled together can not only prevent ammonium chloride crystals from falling out from the gap between the guide component and the receiving component, but also, like a coiled spring, can change the degree of winding according to the distance between the guide component and the receiving component.

[0016] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Combined with appendix Figure 1 To be continued Figure 4As shown, a vibrating screen device for recovering ammonium chloride crystals includes at least two sets of vibrating screens. The discharge port of the primary vibrating screen 10 is connected to the inlet port of the secondary vibrating screen 20. The height of the primary vibrating screen 10 is higher than that of the secondary vibrating screen 20. A guide 11 is provided at the discharge port of the primary vibrating screen 10, and a receiving 21 is provided at the inlet port of the secondary vibrating screen 20. (See attached diagram.) Figure 2 and attached Figure 4 As shown, the material guide 11 of the primary vibrating screen 10 is connected to the material receiving part 21 of the secondary vibrating screen 20. The material guide 11 is provided with a first roller shutter part 111, which is hung on the lower side of the edge of the material guide 11. The material receiving part 21 is provided with a second roller shutter part 211, which is located on the upper side of the side guard part 212 of the material receiving part 211. The first roller shutter part 111 and the second roller shutter part 211 are rolled together.

[0018] Since the primary vibrating screen 10 and the secondary vibrating screen 20 are driven by different motors, there is a certain time difference in their movement when screening materials. The distance between the material guide 11 of the primary vibrating screen 10 and the material receiving part 21 of the secondary vibrating screen 20 varies. The first roller curtain 111 and the second roller curtain 211, which are rolled up together, can solve this problem.

[0019] As attached Figure 4 As shown, when the primary vibrating screen 10 and the secondary vibrating screen 20 screen materials simultaneously, a certain relative movement occurs between the guide component 11 of the primary vibrating screen 10 and the receiving component 21 of the secondary vibrating screen 20. The first roller curtain 111 and the second roller curtain 211 are mutually wound together, which can prevent ammonium chloride crystals from falling out from the gap between the guide component 11 and the receiving component 21, and can also change the degree of winding as the distance between the guide component 11 and the receiving component 21 changes, just like a coiled spring.

[0020] As attached Figure 4 As shown, the guide member 11 has wing plate portions 112 on both sides for connecting with the side plates 12 of the primary vibrating screen 10, and the receiving member 21 has a receiving plate portion 213. The distance between the two wing plate portions 112 of the guide member 11 is smaller than the width of the receiving plate portion 213.

[0021] The primary vibrating screen 10 includes a screening box 13, a transmission mechanism 14, and a drive motor 15. A deflection shaft 16 is provided at the screening box 13, and the deflection shaft 16 is poweredly connected to the drive motor 15 through the transmission mechanism 14. The transmission mechanism 14 is specifically a synchronous belt.

[0022] The screening box 13 is provided with floating mechanisms 17 on both sides. The floating mechanism 17 includes a first spring group 171 and a second spring group 172, which are respectively located on both sides of the deflection shaft 16. The upper end of the first spring group 171 is connected to the screening box 13, and the lower end of the first spring group 171 is connected to the support 18 at the bottom of the screening box 13.

[0023] Combined with appendix Figure 1 and attached Figure 2 As shown, the drive motor 15 drives the deflection shaft 16 to deflect through the transmission mechanism 14. The deflection shaft 16 causes the screen box 13 to swing left and right. Combined with the elastic force of the first spring group 171 and the second spring group 172 on the screen box 13, the automatic screening of the primary vibrating screen 10 is realized. The structure of the secondary vibrating screen 20 is the same as that of the primary vibrating screen 10.
