Description

Technical Field

[0001] The utility model relates to the technical field of ore washing, in particular to an ore surface washing device. Background Art

[0002] Ore washing is a process of using hydraulic or mechanical force to scrub the ore cemented by clay or containing more mud, so that the ore is broken up, the fine mud on the ore surface is washed off and separated. Placer ores such as gold, platinum, tungsten, tin, and ores of lead, copper, iron, manganese, etc. with deeper oxidation and weathering degrees usually need to be washed before crushing or beneficiation to remove part of the gangue or clay.

[0003] Ore washing consists of two operations: breaking up and separating. The breaking-up operation mainly uses the flushing and soaking action of water to expand and break up the clay, and sometimes mechanical impact, stirring and abrasion are also used to accelerate the breaking-up process. The separating operation mainly separates the clay from the ore particles according to different particle sizes. According to the particle size characteristics of the raw ore, the separating operation can adopt wet screening or hydraulic classification, or both at the same time.

[0004] Ore washing can avoid the clogging of crushing and screening equipment by the mud in the clay-containing mineral raw materials. If the raw materials contain soluble useful or harmful components, ore washing is also required. The ease of washing ore mud from ore is expressed by the washability of the ore, which is divided into difficult to wash, moderately washable and easy to wash, and is mainly related to the nature, content and state of clay in the ore. Ore washing can be carried out in a scrubbing machine or in screening and classification equipment.

[0005] A patent document with the publication number CN208643479U, a vibrating ore washer, uses a cylindrical screen to rotate in a washing tank, which can clean the ore to be washed without dead angles, and the cleaning is more comprehensive and cleaner. The sewage is automatically discharged, and clean water is continuously and automatically injected into the washing tank to keep the water quality in the washing tank at a balanced level. The cleaning of the ore is more effective and rapid. After the cleaning is completed, since the washing tank and the cylindrical screen are inclined, the impurities and the ore are discharged from the slag discharge port successively.

Detailed implementation mode

[0027] The technical solution in the embodiment of this application is to solve the problems in the above background technology, and the general idea is as follows:

[0028] Embodiment 1:

[0029] This embodiment introduces the specific structure of an ore surface washing device, specifically referring to Figures 1-3 As shown, it includes a cleaning structure 2, a vibrating screen hopper 6 arranged at the bottom of the cleaning structure 2, and a waste water hopper 4 assembled to the bottom of the vibrating screen hopper 6. The primary screen 1 is assembled and connected to the inner wall of the top of the vibrating screen hopper 6, and the secondary screen 3 is assembled and connected to the inner wall of the middle of the vibrating screen hopper 6;

[0030] As Figure 4 shown, the cleaning structure 2 includes a first cleaning arm 201 and a second cleaning arm 202, and a plurality of cleaning nozzles 208 are assembled and connected inside both the first cleaning arm 201 and the second cleaning arm 202;

[0031] Among them, in order to enable the first cleaning arm 201 and the second cleaning arm 202 to support the cleaning nozzles 208 at both ends of the vibrating screen hopper 6 to spray water on the sand and gravel at the top of the primary screen 1, as Figure 4 shown, vertical plates 207 are arranged at both ends of the first cleaning arm 201 and the second cleaning arm 202. A support disk 212 and a control panel 203 are arranged on the outer sides of the two vertical plates 207. A first connecting rod 213 is processed at the center of one side of the support disk 212 and the control panel 203. By passing one end of the first connecting rod 213 through the inside of the vertical plate 207 and pin-connecting it to the inside of the first cleaning arm 201 or the second cleaning arm 202, and one end of the vertical plate 207 is assembled to the outer wall of the vibrating screen hopper 6, the first cleaning arm 201 and the second cleaning arm 202 can be erected on the top of the vibrating screen hopper 6 by means of the vertical plate 207, the control panel 203, the support disk 212 and the eccentric hole 211;

[0032] Secondly, by connecting the top of the wastewater hopper 4 with the bottom of the vibrating screen hopper 6, and respectively arranging the first cleaning arm 201 and the second cleaning arm 202 at the tops of both ends of the vibrating screen hopper 6, with one end of each of the multiple cleaning nozzles 208 facing the surface of the primary screen 1 and connecting one end of each of the multiple cleaning nozzles 208 to the water supply pipe, on the basis of the existing vibrating screen working, the cleaning nozzles 208 can spray water on the ore on the vibrating screen;

[0033] Meanwhile, when the water is cleaning the ore on the primary screen 1, a part of the small-particle ore passes through the inside of the primary screen 1 and falls on the top of the secondary screen 3, and with the water flowing down from the inside of the primary screen 1, the cleaning work on the ore on the top of the secondary screen 3 continues;

[0034] As Figure 1 and Figure 2 shown, a support base 5 is assembled and connected to the outer wall at the bottom of the vibrating screen hopper 6. By making the support base 5 support the vibrating screen hopper 6 to be inclined, and the primary screen 1 and the secondary screen 3 are in a parallel state inside the vibrating screen hopper 6, the wastewater hopper 4 can be located inside the support base 5 to collect the sewage and fine gravel during the cleaning process and finally discharge them to the outside from its bottom.

[0035] By adopting the above technical solutions:

[0036] In the above design, the primary screen 1 and the secondary screen 3 are arranged inside the vibrating screen hopper 6, and a wastewater hopper 4 connected to the inside thereof is assembled at the bottom of the vibrating screen hopper 6. When one end of the cleaning nozzles 208 on the first cleaning arm 201 and the second cleaning arm 202 is connected to the water pipe, water can be sprayed out from one end of the cleaning nozzles 208 to clean the ore on the top of the primary screen 1. During the cleaning process, the sewage falls to the bottom, and it can be ensured that the ore smaller than the mesh holes of the primary screen 1 falls on the top of the secondary screen 3 and continues to be cleaned. Finally, the wastewater hopper 4 collects the sewage and fine gravel, which is beneficial to synchronously carry out the screening and cleaning work during the ore transportation process, beneficial to improving the production efficiency and does not affect the batch production of ore.

[0037] Embodiment 2:

Round rods 209 are processed on the surfaces at both ends of the linkage arm 210;

[0039] Among them, by inserting two round rods 209 into the eccentric holes 211 on two support disks 212 respectively, during the rotation of the second cleaning arm 202, the first connecting rod 213 and the support disk 212 are driven to rotate, thereby driving the first cleaning arm 201 to rotate, which is beneficial to synchronously controlling the angles of multiple cleaning nozzles 208 on the first cleaning arm 201 and the second cleaning arm 202 with respect to the surface of the primary screen 1;

[0040] Secondly, in order to facilitate the control of the rotation of the second cleaning arm 202 and, based on the above structure, enable the first cleaning arm 201 to rotate synchronously, as Figures 2-4 shown, a toothed ring 204 is machined on the surface of a control disk 203.
