Description

Technical Field

[0001] The utility model relates to the technical field of ore dehydration, in particular to a phosphate ore dehydration device. Background Art

[0002] Phosphate ore is an ore containing phosphorus, which is mostly produced in sedimentary rocks, but also in metamorphic rocks and igneous rocks. Except for some individual cases, the phosphorus in the mineral always exists in the form of orthophosphate. The main mineral of phosphorus is apatite.

[0003] After mining, phosphate rock needs to be washed with water to separate the ore from the soil. After separation, dehydration is carried out. The dehydration process is usually carried out on a dehydration screen. The dehydration screen vibrates to separate the ore and water to achieve the dehydration effect.

[0004] The above-mentioned dehydration process mainly utilizes vibration to dehydrate. When the dehydration screen vibrates, the ore vibrates together. The ore moves upward under the action of vibration and is separated from the dehydration screen. Then, the ore moves downward under the action of gravity and collides with the dehydration screen. At this time, the water is separated from the ore under the action of inertia and discharged from the sieve holes of the dehydration screen. In this process, some water will still adhere to the surface of the ore. Therefore, a phosphate ore dehydration device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above description, the utility model provides a phosphate ore dehydration device to solve the problem that water still adheres to the surface of the ore after dehydration by the existing dehydration screen.

[0006] The utility model provides a technical solution to the above-mentioned technical problems as follows: a phosphate ore dehydration device, comprising: a body, which comprises a support frame, a box body and a dehydration screen plate, the dehydration screen plate is arranged inside the box body, a positioning mechanism is connected to the support frame and the top plate at the same time, and comprises a threaded rod, a spacer, a support spring and a support tube, the threaded rod is connected to the support frame through a threaded cap and a fixing nut, and passes through the dehydration screen plate; a support tube, which is arranged between the support frame and the fixing nut; a support spring, which is arranged between the upper threaded cap and the fixing nut; a top plate, which is arranged between the support spring and the fixing nut, and is sleeved on the outside of the threaded rod.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the support frame includes a frame body, and an upper surface of the frame body is provided with a mounting hole.

[0009] Furthermore, threads are provided at both ends of the threaded rod, the threaded rod passes through the mounting hole, and the threaded caps are provided at both ends of the threaded rod.

[0010] Furthermore, the support cylinder is a hollow cylinder, which passes through the dehydration screen plate and is located below the top plate.

[0011] Furthermore, a gasket, a fixing nut and a protective sleeve are sequentially arranged above the support tube from bottom to top, and the support tube, the gasket, the fixing nut and the protective sleeve are all sleeved on the outside of the threaded rod.

[0012] Furthermore, the fixing nut is threadedly connected to the threaded rod, and the protective sleeve is a rubber sleeve, which is sleeved on the outside of the fixing nut.

[0013] Furthermore, the threaded rod passes through the top plate, and the top plate is arranged above the protective sleeve and contacts the upper surface of the protective sleeve.

[0014] Furthermore, a support spring and a spacer are sequentially arranged above the top plate from bottom to top, and the spacer and the support spring are both sleeved on the outside of the threaded rod and located between the threaded cap and the top plate, and the support spring is in contact with the upper surface of the top plate.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] 1. The utility model sets the top plate and the positioning mechanism and other components, and the positioning mechanism is fixed on the top of the support frame through the matching relationship between the positioning mechanism and the support frame. When the dewatering screen is powered on, the box body and the dewatering screen plate are in a vibrating state, and the ore on the surface of the dewatering screen collides with the top plate under the action of vibration, so that the water on the surface of the ore is separated from the ore under the action of force;

[0017] 2. By setting the supporting spring and the protective cover, the top plate can move upward when hit by the ore, and reset under the action of the elastic force of the supporting spring. In this process, the protective cover plays a buffering role to avoid the negative impact on the entire positioning mechanism when the top plate is reset, so as to extend the practical life of the dewatering screen.

[0029] See also Figure 1 and Figure 4 , a phosphate rock dehydration device, comprising:

[0030] The machine body includes a support frame 1, a box body 2 and a dewatering screen plate 3, wherein:

[0031] The dewatering screen plate 3 is arranged inside the box body 2. The support frame 1 includes a frame body 111. The upper surface of the frame body 111 is provided with a mounting hole 112.

[0032] Based on the above, the support frame 1, box body 2 and dewatering screen plate 3 in the machine body are all existing technologies. The machine body is a dewatering screen body. Since the dewatering screen is an existing mature technology, its specific structure and principle are not described here. The description of the support frame 1, box body 2 and dewatering screen plate 3 here only serves to facilitate the description of the positioning mechanism.

[0033] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the positioning mechanism is connected to the support frame 1 and the top plate 4 at the same time, and includes a threaded rod 5, a spacer 7, a support spring 8 and a support cylinder 12, wherein:

[0034] A threaded rod 5, which is connected to the support frame 1 through a threaded cap 6 and a fixing nut 10, and passes through the dewatering screen plate 3, both ends of the threaded rod 5 are provided with threads, the threaded rod 5 passes through the mounting hole 112, and both ends of the threaded rod 5 are provided with the threaded cap 6;

[0035] A support cylinder 12 is disposed between the support frame 1 and the fixing nut 10. The support cylinder 12 is a hollow cylinder. The support cylinder 12 passes through the dewatering screen plate 3 and is located below the top plate 4. A gasket 11, a fixing nut 10 and a protective sleeve 9 are sequentially disposed above the support cylinder 12 from bottom to top. The support cylinder 12, the gasket 11, the fixing nut 10 and the protective sleeve 9 are all sleeved on the outside of the threaded rod 5.

[0036] The fixing nut 10 is threadedly connected to the threaded rod 5, and the protective sleeve 9 is a rubber sleeve, which is sleeved on the outside of the fixing nut 10.

[0037] A support spring 8, which is arranged between the threaded cap 6 and the fixing nut 10 above;

[0038] A top plate 4, which is arranged between the support spring 8 and the fixing nut 10, and is sleeved on the outside of the threaded rod 5. The top of the top plate 4 is provided with a support spring 8 and a spacer 7 from bottom to top. The spacer 7 and the support spring 8 are both sleeved on the outside of the threaded rod 5 and located between the threaded cap 6 and the top plate 4. The support spring 8 is in contact with the upper surface of the top plate 4;

[0039] Based on the above, the positioning mechanism plays a role in positioning the top plate 4, so that the top plate 4 is not directly connected to the box body 2 and the dewatering screen plate 3, thereby reducing the impact of vibration. The setting of the support cylinder 12 plays a role in providing sufficient supporting force, and limits the distance between the top plate 4 and the dewatering screen plate 3 to ensure that the phosphate ore can pass normally. The setting of the support spring 8 enables the top plate 4 to move vertically. When the top plate 4 is hit by the ore, it can move vertically, which plays a buffering role. While achieving the dehydration effect, it can avoid damage to the top plate 4 caused by the impact.

[0040] In actual use, the phosphate ore is transferred between the top plate 4 and the dewatering screen plate 3. At this time, the machine body is powered on to generate vibration, and the phosphate ore moves along the direction of the dewatering screen plate 3 under the action of vibration.

[0041] During the vibration process, the phosphate ore moves upward under the action of the vibration force, and collides with the top plate 4 after the movement. At this time, the water on the surface of the phosphate ore is separated from the phosphate ore under the action of the impact force, and falls downward under the action of gravity. When the phosphate ore moves downward under the action of gravity, the phosphate ore collides with the dewatering screen plate 3. At this time, the water on the surface of the phosphate ore is separated from the phosphate ore under the action of the impact force, and passes through the dewatering screen plate 3 to be discharged;

[0042] Compared with the traditional dewatering screen, the dewatering screen is provided with a top plate 4, so that the phosphate ore can collide with the top plate 4 and the dewatering screen plate 3 in turn during the vibration process, thereby separating the water on the surface of the phosphate ore from the phosphate ore. Compared with the dewatering screen only provided with the dewatering screen plate 3, the dewatering screen makes more full use of the vibration of the phosphate ore, so that the phosphate ore experiences more collisions (i.e., the dehydration process), thereby increasing the dehydration effect.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
