Abstract
The invention provides equipment capable of reducing bauxite ore dressing concentrate moisture and well forming a concentrate filter cake. The equipment consists of a semi-buried type settling tank, a diaphragm pressing type filter press, a front treatment tank, a gas-liquid mixing pump, a gas-liquid reaction pump and a circulating water tank. The equipment capable of reducing bauxite ore dressing concentrate moisture and well forming the concentrate filter cake can dehydrate ore for 1-5 times and squeeze the ore for four times so as to form the concentrate filter cake; and the equipment is reasonable in distribution, stable in running and smooth in operation. The moisture content of the concentrate filter cake is controlled to be 10-14%. The concentrate filter cake is good in forming so as to completely eradicate the slurry state and be stably stored, and the phenomena of flowing and splashing, shortfall, penalty and environmental pollution in transportation are avoided.
Description
Technical field
The present invention relates to aluminium ore technique of preparing field, specifically relate to a kind of equipment that reduces ore concentration of bauxite concentrate moisture, the forming of concentrate filter cake.
Background technology
Ore concentration of bauxite concentrate moisture, moulding are important index very, control ore concentration of bauxite concentrate moisture at present, moulding generally is the way that adopts ceramic filter, vertical-disk filter and the dehydration of diaphragm pressing filter.The filtering characteristics of ceramic filter are that the concentrate production capacity is low, energy consumption big, moisture 15-17%, and moulding is bad; The filtering characteristics of vertical-disk filter are that the concentrate production capacity is big, energy consumption is big, moisture is greater than 20, and moulding is bad; The filtering characteristics of diaphragm pressing filter are that the concentrate production capacity is moderate, energy consumption is low, moisture about 15%, and moulding is bad.Because diaphragm pressing filter production capacity is moderate, energy consumption is low, moisture content is appropriate, being used for the bauxite concentrate filtration unit at present mainly is the diaphragm pressing filter.No matter be to use the producer of concentrate, the dressing-works that still produces concentrate, the low more economic benefit of moisture is good more, therefore reduces the good thing that concentrate moisture is a doulbe-sides' victory, also is the secular pursuit in concentrate dressing-works.Although pass through the concentrate filter cake of diaphragm pressing filter press filtration at present; Basically can satisfy production, but moisture is high slightly, particularly the moulding of concentrate filter cake is bad; Be paralysed mud shape; For the ore concentration of bauxite factory of independent construction, be catastrophic, subject matter be deposit that difficulty, traffic flow are spilt, missing-ton, fine, contaminate environment.Therefore, low, the forming of filter cake moisture content is very important during concentrate.
The technical problem that ore concentration of bauxite essence mine dehydration, moulding exist: concentrate moisture is higher, and the moulding of concentrate filter cake is bad, is paralysed mud shape.
Summary of the invention
The present invention provides a kind of equipment that reduces ore concentration of bauxite concentrate moisture, the forming of concentrate filter cake in order to address the above problem.
Be achieved in that in order to address the above problem the present invention a kind of equipment that reduces ore concentration of bauxite concentrate moisture, the forming of concentrate filter cake is by partly buried subsider, diaphragm pressing formula pressure filter, processing forebay, gas-liquid mixing pump, gas liquid reaction pump, circulating water pool are formed; The underflow end of half buried subsider is connected to diaphragm pressing formula pressure filter opening for feed; Effluent head is connected to handles the forebay opening for feed; Pressure filter liquid phase discharge end connection processing forebay opening for feed; Handle the bottom, forebay gas-liquid mixing pump is installed; Gas-liquid mixing pump is connected to circulating water pool through the gas liquid reaction pump, and the circulating water pool riser is connected to the entrance end of half buried subsider, and the underflow end connects diaphragm pressing formula pressure filter opening for feed.Described processing forebay is equipped with plasma generator.
Beneficial effect of the present invention is: can to ore carry out 1-5 time the dehydration, four times the squeezing moulding establish one's own system; Distribute rationally, operate steadily, operate smoothness.The concentrate filter cake moisture content is controlled at 10-14%.The moulding of concentrate filter cake is good, stops paralysed mud shape, and stable depositing avoids that traffic flow is spilt, missing-ton, fine, contaminate environment phenomenon.
Description of drawings
Fig. 1 is a kind of device structure block diagram that reduces ore concentration of bauxite concentrate moisture, the forming of concentrate filter cake of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further specified: a kind of equipment that reduces ore concentration of bauxite concentrate moisture, the forming of concentrate filter cake as shown in Figure 1 is made up of half buried subsider, diaphragm pressing formula pressure filter, processing forebay, gas-liquid mixing pump, gas liquid reaction pump, circulating water pool; The underflow end of half buried subsider is connected to diaphragm pressing formula pressure filter opening for feed; Effluent head is connected to handles the forebay opening for feed; Pressure filter liquid phase discharge end connection processing forebay opening for feed; Handle the bottom, forebay gas-liquid mixing pump is installed; Gas-liquid mixing pump is connected to circulating water pool through the gas liquid reaction pump, and the circulating water pool riser is connected to the entrance end of half buried subsider, and the underflow end connects diaphragm pressing formula pressure filter opening for feed.Described processing forebay is equipped with plasma generator.
With five dehydrations is example, and molding device is the diaphragm pressing filter, and operating method is that half buried subsider height contains underflow admittedly, to the diaphragm pressing filter, after expiring on the material, carries out squeezing the first time moulding, blowing for the first time, dehydration for the second time through underflow pump material loading; Blowing stops, and with the washing for the first time on the diaphragm pressing filter of water in the circulating water pool, squeezes moulding, blowing for the second time, dehydration for the third time for the second time; Blowing stops, and with the washing for the second time on the diaphragm pressing filter of water in the circulating water pool, squeezes moulding, blowing for the third time, the 4th dehydration for the third time; Blowing stops, with clear water washing for the third time on the diaphragm pressing filter, and the 4th squeezing moulding, the 4th blowing, the 5th dehydration, the concentrate filter cake unloads on concentrate blanking belt.
