[Industrial use]

The present invention relates to a conical centrifuge, and more particularly, to a conical centrifuge capable of separating liquids and solids from mixed liquids containing fine solids.

[Prior art]

As is well known, centrifugal separators have been applied to all industrial fields, such as wastewater and chemical treatment or foreign material removal of raw materials.

This kind of centrifugal separator inputs a mixed liquid containing fine solids into the mesh screen which is rotated at high speed by the driving means, and dehydrates the liquid from the mixed liquid and separates and collects the solids by the centrifugal force of the conical mesh screen. do.

As an example of such a conical centrifugal separator, Japanese Utility Model Publication No. 36-1386, Patent Publication No. 39-20693, and Utility Model Publication No. 55-51558 disclose a structure known in the art.

[Problem trying to solve the invention]

As described above, in the conventionally known centrifuge, the liquid is dewatered by the rotation of the mesh screen and sent to the recovery tank, and the solid matter is separated by the centrifugal force to the upper opening while moving on the inclined surface of the mesh screen and recovered to the storage chamber.

In this case, the fine shape of the solid blocks the pores of the mesh screen, so that the continuous loading of the mixed liquid causes the solids to be more loaded, reducing the separation efficiency, and consequently the mesh screen must be replaced.

Japanese Utility Model Publication No. 55-51558 discloses a structure in which a cleaning liquid is sprayed together with a mixed liquid. However, in this case too, hole clogging is still occurring, which only delays the replacement of the short-term mesh screen.

Therefore, the conventional centrifuge is difficult to practically use as a commodity.

In addition, conventionally, when the mixed liquid is added, the supply amount of the mixed liquid is limited by providing a supply pipe of the mixed liquid at the rotational center of the blade which scrapes off the solid matter loaded in the storage chamber. In this case, the supply pipe of the mixed liquid is naturally made of tubules.

In view of the above-described problems of the prior art, an object of the present invention is to provide a conical centrifuge capable of eliminating hole blockage without replacing the mesh screen.

Another object of the present invention is to make it possible to improve the treatment efficiency by further increasing the input amount of the mixed liquid.

[Means to solve the problem]

According to the above object, the centrifugal separator of the present invention injects a mixed liquid containing fine solids into a mesh screen which is rotated at high speed by a driving means, and in the conical centrifuge separating the liquid and solids from the mixed liquid by the centrifugal force. The mesh screen is coupled to the upper end of the rotating shaft connected to the drive motor; The upper and lower grilles clamping the edges of the opening of the mesh screen are coupled to be slidably axially lifted and rotated in the axial direction via the fixing hollow shaft, and to be rotated in synchronism with the mesh screen by the rotation shaft; The rotating shaft is configured to be moved up and down by an elevating cylinder coupled to the elevating plate via a movable unit housing supporting the movable hollow shaft and seated and fixed to the elevating plate.

Another embodiment of the present invention described above is a centrifugal separator including an inflow means of a folding input pipe installed in a cover part to allow a mixed liquid to be introduced into a housing; Filtering means of the grill member to be rotated by mounting a mesh screen for separating the mixed liquid introduced through the folding input pipe into solids and liquids by centrifugal force; Transmission means of a bearing member which enables the lifting and lowering of the rotating shaft while transmitting and rotating power to the grill member; Elevating drive means for elevating members for elevating the inside and outside of the mesh screen by elevating the rotating shaft interposed in the bearing member to a predetermined height; Removal means of the hair member for contacting the inverted mesh screen by driving the elevating member to shake off the solids; Characterized in that the conical centrifuge comprising a discharge means of the blade for discharging the solids separated by the operation of the hair member to the outside of the housing.

In the above-described configuration of the present invention, in the mesh screen having the opening edge fixed by the upper and lower grilles, the lower inward edge is clamped by the screen fixing plate coupled to the rotating shaft.

The rotating shaft slidingly coupled to the fixed part hollow shaft is formed of a bar-shaped bar in order to rotate the fixed part hollow shaft together, and a hexagon is preferable in consideration of sliding in the axial direction.

By such a configuration, the mesh screen is turned upside down during rotation, and the inside and the outside are changed. As a result, the foreign matter blocking the hole is released by centrifugal force, thereby eliminating the hole clogging without replacing the mesh screen.

In addition, a collecting channel for collecting solids separated by centrifugal force is provided at the upper circumference of the mesh screen. Here, the collecting channel is provided with a blade for attracting the solids to one place, which is fixed to the driven ring gear is configured to be rotated by a drive gear and a motor inscribed to the driven ring gear.

By the driven ring gear, the mixed liquid supply pipe provided at the center of the rotating shaft is formed to be enlarged, which can improve the treatment efficiency by overcoming the limitation of the raw material input amount.

In addition, the said bolt is not shown in a well-known technique.

On the upper side of the upper screen fixing plate 5 described above, a raw material guide tube 4 for guiding the falling of the mixed liquid is fixed integrally. In this case, the raw material guide tube 4 has a plurality of holes 46 for forming a predetermined gap between the upper screen fixing plate 5 and allowing the raw material dropped therebetween to pass.

Therefore, the mixed liquid spread radially by the conical closing nut 11 passes through the hole 46 of the raw material guide tube 4 and is sprinkled onto the inner wall of the mesh screen 7 by centrifugal force.

Rotation of the mesh screen 7 is driven by a driven pulley 33 and a power source connected via a belt 34, a driven pulley 32 fixed to the lower end of the rotating shaft 24, as shown. Achieved by the motor 41. Here, the belt 34 is generally a V belt is used, it is also possible to use a transmission means such as a timing belt.

A movable hollow shaft 28 is integrally coupled to the lower end of the rotary shaft 24 connected to the drive motor 41 by a fixing bolt 31, and the movable hollow shaft 28 is again via a bearing 35. It is rotatably coupled to the movable part housing 26.

Here, the movable part housing 26 and the drive motor 41 are seated and supported on the elevating plate 38 together, and the elevating plate 38 is installed to be moved up and down by the air cylinder 42. It is. In this case, the air cylinder 42 is seated on the upper plate 36 of the case to support the elevating plate 38, through the gap adjusting member 43 to adjust the height of the elevating plate 38. Are combined.

The lifting plate 38, which is moved by the air cylinder 42, is supported by at least four corners by the guide posts 39, in order to prevent flow and maintain straightness, which are rolled through the guide rollers 40. Configured to be contacted.

Therefore, the rotary shaft 24 fixed to the elevating plate 38 is raised and lowered by the operation of the air cylinder 42, which is the upper and lower screen fixing plates 5, 6 fixed to the upper end of the rotary shaft 24 The mesh screen 7 is raised and lowered so that the mesh screen 7 is flipped or straightened.

More specifically, the air cylinder 41 is rotated at high speed by the drive motor 41 and raises the mesh screen 7 separating the mixed liquid, and is reversed in reverse during rotation. In this case, foreign matter adhering to the inner surface of the mesh screen 7 is separated by the centrifugal force.
