Problems solved by technology

[0004] In order to overcome the deficiencies of the existing magnetic press dehydration technology, the present invention provides a device for concentrating and dehydrating magnetic slag water or magnetic materials, that is, a built-in magnetic separation filter press dehydrator, which significantly changes the pressure of the press water because it cannot be discharged in time. Therefore, return to the state of mixing and saturation with the subsequent slag to solve the problem of high moisture content in the slag; at the same time, set the inner tank to improve the impact load capacity of the equipment

Embodiment 1

[0030] combine figure 1 , figure 2 As shown, a built-in magnetic separation filter press dehydrator is used to separate and dehydrate magnetic slag water, including a frame 14, a cantilever bracket 6 arranged on the frame 14, a motor reducer 1, and a coupling 2. Bearing seat 3, outer groove 12, magnetic cylinder 5, feed port 17, drain pipe 11, magnetic cylinder 5 is located in outer groove 12, the supporting end shaft of magnetic cylinder 5 passes through outer groove 12 and one end is supported by bearing seat 3 It is driven to rotate by the motor reducer 1 through the coupling 2; an inner groove 4 is arranged on the inner lower part of the magnetic cylinder 5, and the upper edge of the inner groove 4 is fixed on the cantilever bracket 6; a pressure roller 16 is built in the inner upper part of the magnetic cylinder 5 and The inner cylinder of the magnetic cylinder 5 cooperates to press the slag; that is, the magnetic slag is magnetically adsorbed on the inner cylinder 5.2 ...

Embodiment 2

[0032] In combination with Example 1, such as image 3 As shown, in order to further improve the effect of pressing and dehydrating, we designed the press roller 16 as a filter cartridge 20 with a filtering function. During the pressing and dehydrating process of the filter cartridge 20, a part of the water flows down the outer wall of the filter cartridge 20 to the inner tank. The other part of water enters the filter cartridge 20 through the filter layer of the filter cartridge 20 and falls from the water filter holes 20.1 provided on both ends of the filter cartridge 20 to the inner tank 4, and finally flows into the magnetic separation flow channel 18 through the slag opening 13 of the inner tank to realize Further separation and dehydration.

Embodiment 3

[0034] In combination with embodiment 1 and embodiment 2, such as image 3As shown, three filter cartridges 16 are arranged in the same magnetic cylinder 5, so that the moisture in the dried slag can be compressed step by step on one magnetic cylinder 5, so that the moisture content of the slag is very low. When the equipment is running, the magnetic slag water or magnetic material enters the outer tank 12 from the feed port 17, and then enters the magnetic separation flow channel 18. The magnetic slag material is adsorbed on the inner surface of the magnetic cylinder by the magnetic field of the inner cylindrical surface 5.2 of the magnetic cylinder. The water enters the drain pipe 11; the slag adsorbed on the inner surface of the magnetic cylinder moves out of the liquid surface with the rotation of the magnetic cylinder 5, and is squeezed out by the filter cylinder 16 step by step. The slag conveying belt 7 is output. During this process, the slag conveying belt 7 is driven...

Abstract

The invention discloses a built-in magnetic separation filter pressing dehydrator which is used for equipment for separating, concentrating and dehydrating magnetic slag water or water-containing magnetic materials. The built-in magnetic separation filter pressing dehydrator comprises a rack, a motor reducing gear, a coupler, a bearing block, an outer groove, a magnetic cylinder of which the magnetic field transmits inward, an inner groove, compression rollers, a slag scraping plate, a slag conveying belt, a material inlet, a drainage pipe and the like; the built-in magnetic separation filterpressing dehydrator is characterized in that: a filter pressing cylinder is arranged in the magnetic cylinder, and the magnetic field transmits inward. The built-in magnetic separation filter pressing dehydrator effectively solves the problem that press water and subsequent slag are mixed and saturated, and realizes multi-level pressing on one magnetic cylinder, and tapped slag is low in moisturecontent; and the equipment is high in resistance to impact load, and pollution to the field, which is caused by overflowing during change of the slag water amount can be avoided. The technical schemeand the equipment can be widely applied to separating, concentrating and dehydrating of water-containing magnetic slag or magnetic materials in the fields of metallurgy, machining, ore concentration and the like, the tapped slag is low in moisture content, and the built-in magnetic separation filter pressing dehydrator saves investment, occupies small floor, and can run at low consumption.

Description

technical field [0001] The invention relates to a magnetic separation dehydration device, in particular to a built-in magnetic separation filter press dehydrator, which uses magnetic force to separate, concentrate and dehydrate magnetic slag water or magnetic materials, and belongs to the technical field of magnetic separation and dehydration. Background technique [0002] In terms of ore dressing and dense medium coal washing, drum type magnetic separation equipment is mostly used for the separation, concentration and dehydration of magnetic materials. In recent years, in the treatment of industrial wastewater such as metallurgical wastewater and machining wastewater at home and abroad, magnetic separation and purification technology has also been applied; at the same time, magnetic pressing concentration and dehydration technology is also developing. Obviously, the use of magnetic separation technology to separate, concentrate and dehydrate aqueous magnetic slag water or m...
