Description

Mould pressing barrel for pressure type solid-liquid separation device

Technical Field

The utility model relates to a solid-liquid separation equipment, concretely relates to a mould pressing section of thick bamboo for pressure type solid-liquid separation equipment.

Background

The solid-liquid separation is a process for removing suspended solids from a solid-liquid mixture, and the common method and process mainly comprise sedimentation, filtration, centrifugation and the like, and can also be used by combining a plurality of methods to achieve the optimal separation effect. The filter-press type solid-liquid separation process is one kind of filtering process, and based on the filtering mode, certain external pressure is applied to raise the solid-liquid separation efficiency.

In the filtering process, solid-liquid separation is achieved through the selective permeability of a filter screen or other filtering media with filtering channels to the solids in the mixture, that is, the solids in the mixture are selected through the size of the filtering channels, and the liquid and the solids with smaller size are allowed to pass through.

However, in the filter pressing process, part of the solid with a size slightly larger than that of the filtering channel enters the filtering channel under the action of external pressure, but cannot move continuously to pass through the filtering channel completely, and the part of the solid stays in the filtering channel to cause the blockage of the filtering channel, so that the further solid-liquid separation is influenced.

In order to solve the technical problem, the utility model provides a technical scheme as follows: a mould pressing cylinder for a pressure type solid-liquid separation device is provided with a mould pressing cavity, and at least one end of the mould pressing cavity is opened; the mould pressing cylinder is provided with a plurality of filtering channels, each filtering channel comprises an expansion section, and the expansion sections gradually expand from one end to the other end; the small end of the expansion section faces the mould pressing cavity and is communicated with the mould pressing cavity; and a liquid drainage channel communicated with the filtering channel is arranged in the mould pressing cylinder.

Under the externally applied pressure, the impurity that the size slightly is greater than the expansion section tip can follow the expansion section tip and get into filtration passageway, and because the expansion section expands from the tip to the main aspects gradually, filtration passageway reduces the resistance to impurity, and impurity can pass through the expansion section smoothly, and then gets into the drainage channel, finally discharges.

Compare with conventional filtration form, the setting of expansion section when guaranteeing to solid impurity selectivity filtration, has reduced the risk that solid impurity blockked up filtering channel, very big improvement filtration efficiency and effect.

Preferably, the expansion section is a tapered hole; the filtering channel also comprises a conveying section, and the conveying section is perpendicular to the expansion section and is communicated with the large end of the conveying section; one side of the conveying section, which is far away from the expansion section, is an inward-concave smooth curved surface.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

As shown in fig. 1 to 4, a mold pressing cylinder for a pressure type solid-liquid separation device is provided with a mold pressing cavity 14, one end of the mold pressing cavity 14 is open, the other end is connected with a bottom plate 2, and a plurality of filtering channels 13 are arranged in the bottom plate 2; the small end of the expanding section 132 is disposed toward the molding chamber 14 and communicates with the molding chamber 14.

As shown in fig. 1 to 4, a plurality of filter passages 13 are arranged on the die cylinder and distributed annularly around the axis, the filter passages 13 comprise expanding sections 132, and the expanding sections 132 gradually expand from one end to the other end; the small end of the expanding section 132 is disposed toward the molding chamber 14 and communicates with the molding chamber 14.

The expanding section 132 is a tapered hole; since the tapered hole-shaped expanding section 132 is difficult to machine, the die-pressing cylinder needs to be manufactured in a manner that the inner cylinder body and the outer cylinder body are separately machined and are in fit connection, that is, the expanding section 132 is machined on one part of the die-pressing cylinder, and the conveying section 131 is machined on the other part of the die-pressing cylinder. The liquid passing through the expanding section 132 has a large flow rate, and thus, a large impact is applied to the conveying section 131, which easily causes problems such as breakage of the conveying section 131. One side of the conveying section 131 is set to be a smooth curved surface, so that stress concentration is reduced, and risks such as cracks of the conveying section 131 can be effectively reduced.

As shown in fig. 1 to 4, the filtering channel 13 further includes a conveying section 131, and the conveying section 131 is perpendicular to the expanding section 132 and is communicated with the large end of the conveying section 131; the side of the conveying section 131 far away from the expanding section 132 is an inwardly concave smooth curved surface.

Under the externally applied pressure, the impurities with the size slightly larger than the small end of the expansion section 132 can enter the filtering channel 13 from the small end of the expansion section 132, and because the expansion section 132 gradually expands from the small end to the large end, the resistance of the filtering channel 13 to the impurities is reduced, and the impurities can smoothly pass through the expansion section 132, then enter the drainage channel and finally be discharged.

Compared with the conventional filtering mode, the arrangement of the expansion section 132 reduces the risk that the solid impurities block the filtering channel 13 while ensuring the selective filtering of the solid impurities, and greatly improves the filtering efficiency and the filtering effect.

Example two

As shown in fig. 1 to 4, compared with the first embodiment, the present embodiment is different in that the expanding section 132 is a long-strip-shaped groove, and the distance between two wall surfaces of the expanding section 132 gradually increases from one end communicating with the molding chamber 14 to the other end; the bottom of the expanding section 132 is recessed inwards to form a conveying section 131, and the conveying section 131 is a smooth curved surface. The expansion section 132 axially penetrates through the entire molding cylinder, and the opening of the expansion section 132 in the molding cavity 14 is an elongated slit. And a liquid discharge channel 11 communicated with a filtering channel 13 is arranged in the die pressing cylinder.

The expansion section 132 penetrates the entire working surface, and the opening of the expansion section 132 on the working surface is a long strip-shaped gap. Compared with the first form of the embodiment, the scheme of the embodiment is more convenient and fast to process, and split processing is not needed. In addition, the opening of the expanding section 132 on the working surface is in a long strip shape, so that the expanding section can be suitable for filtering and purifying long-strip impurities such as cutting fluid.

One end of the filtering channel in the die pressing cylinder is expanded towards the other end, so that solid impurities can be smoothly discharged after entering the filtering channel under the action of high pressure, the filtering channel cannot be blocked, and the filtering efficiency is improved.

In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
