Description

Technical Field

[0001] The invention relates to the technical field of ore mining, in particular to a drum-type layer screen desludging machine for ore mining. Background Art

[0002] Before crushing, grinding and selection, the ore needs to be desludged by a drum desludging machine because of its high mud content. This provides high-quality ore raw materials for the ore dressing production line, thereby effectively improving the ore utilization rate. It is also of great significance to the green development path of reducing pollution and improving the ecological environment.

[0003] The existing drum demuding machine has a short roller interval, and its efficiency in removing stubborn mud on the ore is too low, resulting in the ore still containing a large amount of mud after the demuding process, which is very disadvantageous for subsequent processing and production. Summary of the invention

[0004] In order to overcome the shortcoming of the existing drum demuding machine that the drum space is short and the ore mud cannot be completely removed, the present invention provides an ore mining drum-type layer screen demuding machine with controllable drum space.

[0005] A drum-type layer screen and demudger for ore mining comprises a support, a motor, a gear, a gear ring and a screen drum. The support is inclined with the left side higher than the right side. The screen drum is rotatably connected to the support. The motor is fixed to the left end of the support through a bracket. The output shaft of the motor is keyed to a gear. The gear ring is arranged at the periphery of both ends of the screen drum. The gear and the gear ring are meshed with each other. A partition mechanism capable of adjusting the internal structure of the screen drum is also included.

[0006] As a preferred technical solution of the present invention, the partition mechanism includes a partition, a fixed block, an arc-shaped fixed rod and a limit block. The partition is rotatably connected to the inner cavity of the screen cylinder, the limit block is fixed at both ends of the partition and is located outside the screen cylinder, the fixed block is symmetrically fixed to the outside of the screen cylinder, the arc-shaped fixed rod is slidably connected to the fixed block and a reset spring is arranged between the two.

[0007] As a preferred technical solution of the present invention, a spray assembly is also included. The spray assembly includes a water tank and a spray box. The water tank is fixedly connected to the upper part of the support, and the spray box is arranged at the bottom of the water tank.

[0008] As a preferred technical solution of the present invention, it also includes a flip assembly, which includes a push rod and a first connecting block. The push rod is fixedly connected to both sides of the arc-shaped fixed rod, and the first connecting block is fixedly connected to the limit block.

[0009] As a preferred technical solution of the present invention, it also includes a control mechanism, which includes a push rod, a second connecting block and a water baffle. The push rod is fixed to the right end of the screen drum, the water baffle is connected to the bottom of the spray box through a rotating shaft, and the second connecting block is connected to the water baffle.

[0010] As a preferred technical solution of the present invention, it also includes a water-spreading roller, which is rotatably connected to the upper end of the support through a bracket, and the water-spreading roller is connected to the output shaft of the motor through a coupling.

[0011] As a preferred technical solution of the present invention, it also includes a fixing component, which includes a fixing plate and a fixing cone. The fixing plate is fixed to the left and right ends of the bottom of the support, and the fixing cone is slidably connected to the fixing plate and passes through the support.

[0012] Through the above scheme, the beneficial effects of the present invention are:

[0013] 1. Set up a partition with a concave notch, flip the partition to divide the screen drum into sections, and then use an arc-shaped fixing rod to limit and fix the partition. The ore will be blocked by the partition and slowly pass through the concave notch, thereby increasing the rolling time and improving the desludging efficiency.

[0014] 2. Sufficient clean water is introduced into the water tank, and the spray box sprays the clean water onto the screen drum to improve the mud removal efficiency and remove dust. When the push rod in the control mechanism rotates to push the second connecting block, the spray box opens to spray the screen drum, and when the push rod does not contact the second connecting block, the water baffle closes the spray box, thereby saving water and reducing production costs.

[0015] 3. The fixing cone can slide on the fixing plate and penetrate into the ground to improve the stability of the support. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0029] Example 1

[0030] A drum-type layer screen desludging machine for ore mining, such as Figure 1-Figure 11 As shown, it includes a support 1, a motor 2, a gear 201, a gear ring 202 and a screen drum 3. The support 1 is inclined with the left side higher than the right side. The screen drum 3 is rotatably connected to the support 1. The motor 2 is fixed to the left end of the support 1 through a bracket. The output shaft of the motor 2 is keyed to the gear 201. The gear ring 202 is arranged at the two ends of the screen drum 3. The gear 201 and the gear ring 202 are meshed with each other. It also includes a partition mechanism 4 that can adjust the internal structure of the screen drum 3.

[0031] like Figure 1 , Figure 3 and Figure 4As shown, the partition mechanism 4 includes a partition 401, a fixed block 402, an arc-shaped fixed rod 403 and a limit block 405. The partition 401 is rotatably connected to the inner cavity of the screen drum 3, the limit blocks 405 are fixed at both ends of the partition 401 and are located outside the screen drum 3, the fixed block 402 is symmetrically fixed to the outside of the screen drum 3, the arc-shaped fixed rod 403 is slidably connected to the fixed block 402 and a return spring 404 is arranged between the two; the ore is introduced from the left side of the screen drum 3, and then the motor 2 is turned on through the gear ring 201 02 combination, the motor 2 will drive the screen drum 3 to rotate. If there is too much mud and sand in the ore, the partition 401 can be limited and fixed by the arc-shaped fixing rod 403. Since the partition 401 is provided with a concave notch, when the screen drum 3 rotates to remove mud, the ore will be blocked by the partition 401 and pass through the concave notch, thereby increasing the rolling time to improve the mud removal efficiency. For conventional ore, the partition 401 is turned over and limited and fixed by the arc-shaped fixing rod 403, and the ore can pass through the screen drum 3 unimpeded for conventional mud removal.

[0032] Example 2

[0033] On the basis of Example 1, Figure 1 , Figure 5 and Figure 6 As shown, a spray assembly 5 is also included, and the spray assembly 5 includes a water tank 501 and a spray box 502. The water tank 501 is fixedly connected to the upper part of the support 1, and the spray box 502 is arranged at the bottom of the water tank 501; a sufficient amount of clean water is introduced into the water tank 501, and the spray box 502 sprays the clean water onto the screen drum 3 to improve the mud removal efficiency.

[0034] like Figure 1 and Figure 7 As shown, it also includes a flip assembly 6, which includes a push rod 601 and a first connecting block 602. The push rod 601 is fixedly connected to both sides of the arc-shaped fixed rod 403, and the first connecting block 602 is fixedly connected to the limit block 405; when the staff pulls the arc-shaped fixed rod 403, the push rod 601 will contact and push the first connecting block 602 to rotate, thereby driving the partition 401 to rotate, realizing automated operation, and no manual rotation of the screen drum 3 is required.

[0035] like Figure 1 and Figure 8As shown, it also includes a control mechanism 7, which includes a push rod 701, a second connecting block 702 and a water baffle 703.

During the pushing process, the water baffle 703 rotates with the second connecting block 702. The effect achieved by this mechanism is that when the push rod 701 rotates to push the second connecting block 702, the spray box 502 is opened to spray the sieve drum 3, and when the push rod 701 does not contact the second connecting block 702, the water baffle 703 closes the spray box 502, thereby saving water and reducing production costs.

[0036] like Figure 1 and Fig. 9 As shown, it also includes a water-spreading roller 8, which is rotatably connected to the upper end of the support 1 through a bracket, and is connected to the output shaft of the motor 2 through a coupling; when the motor 2 drives the screen drum 3 to rotate, the water-spreading roller 8 rotates at the same time, and the water sprayed by the spray box 502 will be scattered by the water-spreading roller 8 and evenly fall on the screen drum 3, so as to achieve the effect of uniform mud removal.

[0037] like Figure 1 , Fig.10 and Fig.11 As shown, it also includes a fixing component 9, which includes a fixing plate 901 and a fixing cone 902. The fixing plate 901 is fixedly connected to the left and right ends of the bottom of the support 1, and the fixing cone 902 is slidably connected to the fixing plate 901 and passes through the support 1; the fixing cone 902 can slide on the fixing plate 901 and penetrate into the ground to improve the stability of the support 1.
