Description
Technical Field
The invention relates to a bag-type solid-liquid separation device and a separation method, and belongs to the technical field of solid-liquid separation.
Background
Solid-liquid separation is a core unit in the chemical process, and the methods for realizing solid-liquid separation mainly comprise sedimentation, filtration, flotation and the like, or the combination of several methods. The filtration is the most common solid-liquid separation method, and according to the difference of particle sizes of different particles, the solid particles in a solid-liquid mixture are intercepted on a medium under the action of an external force, and liquid is separated through a pore channel, so that the purpose of solid-liquid separation is achieved. Because the filtering method is simple to operate and high in separation precision, under the condition of high solid-liquid separation requirement, the filtering is a commonly used method, wherein bag type filtering is the most common filtering equipment, the separation of an aqueous system and an organic solid-liquid system can be met by adjusting the material of the filtering bag, and the separation of micron-sized particles in the solid-liquid system can be realized by changing the aperture size of the filtering bag, so that the advantages of high filtering and separating precision are achieved, the solid content of the removed mud cake is high, and the solid content in the liquid phase is low.
CN 104667598A discloses a common bag filter, in which a solid-liquid mixture is retained on a cloth bag under the action of external pressure, liquid passes through the cloth bag to realize solid-liquid separation, and when the cloth bag is saturated with solid, the solid is separated from the cloth bag by an internal back-washing mechanism and is deposited in a recovery tank. Local backwashing often occurs in the backwashing process and is also short-circuited, so that the liquid content in the washed solids is too high, and the filtration efficiency is seriously influenced.
CN 103041635A discloses an improved bag filter, which makes the air source center almost equal to pass through the material by improving the structure of the compressed air distributor, solves the phenomenon of 'short circuit' of the compressed air in the filter pressing process, and the air source center distribution pipe can be adjusted according to the height of the material. However, when the bag is saturated with solid material, such conventional bag filters require manual removal of the bag to pour the solid material out of the bag, and often require flushing if the solid material has a certain viscosity.
CN 106944265A discloses a bag-turning type centrifuge, and the structure realizes bag turning of a filter bag through complex transmission and moving shaft pushing action, and the bag-turning type centrifuge has the defects of complex structure, more accessory structures, large volume, small filter area, small solid-liquid treatment capacity and the like.
When a traditional bag filter is saturated with solid materials in a filter bag, the traditional bag filter generally has the following two solutions, one is that the solid materials in the filter bag are washed down by using a back washing means to realize regeneration and recycling of the filter bag, the back washing can cause the liquid content in the solid materials to be greatly increased, and the efficiency of solid-liquid reduction is reduced; the other method is to take out the filter bag and manually pour out the solid materials in the filter bag, which is complex in operation on one hand and brings potential hidden dangers to the safety of human bodies and the environment when toxic and harmful solid and liquid are treated on the other hand.
The filter bag is inverted, so that the solid materials gathered on the filter bag are shaken off, the use of backwash liquid is avoided, the moisture content of the solid materials is low, the filter bag is not manually disassembled, the operation efficiency is improved, and the risk of harm of the materials to a human body is reduced. The invention is characterized in that the filter bag is reversely rotated in the filter by a hydraulic driving device, so that solid materials accumulated in the filter bag are separated from the filter bag and are discharged through a solid discharge port.

The device according to claim 1 or 2, characterized in that the lower opening of the upper cylinder (1) is connected with the gate valve (3) by a flange; the upper part of the lower cylinder (2) is provided with an opening, and the upper part of the opening is connected with the gate valve (3) through a flange.
4. A device according to any one of claims 1-3, characterized in that the cloth bag mechanism (5) is a cylinder with an open lower end, comprising a cloth bag (17) which is connected at its lower end to the lower end of the upper cylinder (1) and at its upper end to a clamp which is connected to the drive rod (7).
5. The device according to any one of claims 1 to 4, characterized in that the clamping plates comprise an upper clamping plate (15) and a lower clamping plate (16), the cloth bag (17) is clamped between the upper clamping plate (15) and the lower clamping plate (16), and the upper clamping plate (15) and the lower clamping plate (16) are connected through bolts.
6. The device according to any one of claims 1 to 5, characterized in that the lower part of the side wall of the upper cylinder (1) is provided with a material inlet (10) and a residue outlet (12), and the upper part of the side wall of the upper cylinder (1) is provided with a filtrate outlet (11).
7. The device according to any one of claims 1 to 6, characterized in that the bottom of the lower cylinder (2) is provided with a discharge opening (6).
8. Device according to any one of claims 1 to 7, characterized in that the maximum travel of the transmission rod (7) does not exceed twice the height of the cloth bag mechanism (5); and/or the height of the cloth bag mechanism (5) is 50% -90% of the height of the upper cylinder body (1).
9. A method for solid-liquid separation using the apparatus of any one of claims 1 to 8, comprising the steps of:
s1, enabling the two-phase mixture to enter a cloth bag mechanism (5) of an upper barrel (1), intercepting a solid phase, and discharging a liquid phase;
s2, stopping feeding, and discharging residual materials in the upper barrel body (1);
s3, opening the gate valve (3), and pushing the transmission rod (7) to move downwards by the driving device (4) to enable the cloth bag (17) of the cloth bag mechanism (5) to move downwards and reversely, so that solid materials on the cloth bag (17) fall off;
s4, enabling the transmission rod (7) to descend to reach the maximum displacement, moving between the initial position and the maximum displacement position, and shaking off the residual materials;
s5, enabling the transmission rod (7) to ascend to return to the initial position, and enabling the cloth bag (17) to restore to the original state.
10. Use of the apparatus according to any one of claims 1 to 8 or the process according to claim 9 for the solid-liquid separation of wax material.
