[0002] The combined filtrate distribution device of the disc filter, such as patent document CN114931790B, divides the filtrate into independent clear filtrate area and turbid filtrate area through turbid and clear distribution plates. If it is necessary to adjust the ratio of the clear filtrate area to the turbid filtrate area, the disc filter needs to be stopped, and then the outer frame and distribution components of the distribution device need to be disassembled, which is time-consuming and labor-intensive.

[0003] Patent document CN111593595B discloses a filtrate distribution device of a multi-disc concentrator, wherein a distribution plate driving mechanism includes a distribution plate driving telescopic rod inclined downward and pointing to the distribution plate, the distribution plate driving telescopic rod is connected to the distribution plate through a connecting rod assembly, and the distribution plate driving telescopic rod is extended and retracted to drive the distribution plate to rotate within a certain angle range. Although this structure realizes the adjustment of the filtrate ratio outside the machine, it is prone to the following problems:

[0004] 1. The distribution plate driving telescopic rod is a straight telescopic rod with a long overall length. It is easy to cause torque due to eccentricity, which affects the rotation of the turbid and clear distribution plate and is also easy to cause the telescopic rod to break;

[0005] 2. The distribution plate drives the telescopic rod to enter the turbid filtrate area through the atmospheric area. No seal is set between the two areas, which may easily cause vacuum leakage in the turbid filtrate area and cross-zone. Utility Model Content

[0006] The utility model provides a disk filter combined filtrate distribution device for adjusting filtrate ratio outside the machine. Through the cooperation of a sliding rod, a universal joint and a push rod, even if the push rod and the sliding rod are eccentric, it does not affect the adjustment of the position of the turbid and clear distribution plate.

[0007] The technical solution of the utility model is implemented as follows: a combined filtrate distribution device of a disc filter for adjusting the filtrate ratio outside the machine includes an outer frame and a distribution component, the distribution component includes a fixed frame, a circumferentially sliding turbid and clear distribution piece is arranged in the fixed frame, the turbid and clear distribution piece is hingedly connected to one end of a connecting rod, the other end of the connecting rod is hinged to the lower end of a sliding rod, the upper end of the sliding rod is connected to one end of a push rod through a universal joint, the other end of the push rod is provided with a threaded section, the threaded section passes through the upper end of the outer frame, and is screwed with an adjusting nut.

[0008] Furthermore, a perforation is provided on the end plate of the fixed frame, a sealing assembly is provided at the perforation, and the sliding rod slides through the sealing assembly. Through the setting of the sealing assembly, even if the sliding rod moves up and down, the atmosphere zone and the turbid filtrate zone can be ensured to be independent of each other, avoiding cross-zone.

[0009] Furthermore, the sealing assembly includes an annular T-shaped connecting plate, the T-shaped connecting plate is fixed at the perforation, and a sealing ring is arranged inside the T-shaped connecting plate.

[0010] Furthermore, the universal joint includes a connecting seat, in which a rotating universal ball is arranged, the connecting seat is fixedly connected to the upper end of the sliding rod, and the universal ball is fixedly connected to the lower end of the push rod.

[0011] Furthermore, the connection seat includes a lower connection plate and an upper connection plate, the lower connection plate is fixed to the upper end of the sliding rod, the upper connection plate and the lower connection plate are detachably connected by bolts, the lower connection plate is provided with a lower arc groove that matches the lower side of the universal ball, and the upper connection plate is provided with an upper arc groove that matches the upper side of the universal ball. The setting of the connection seat structure facilitates the connection and disassembly between the push rod and the sliding rod.

[0012] Beneficial effects of the utility model:

[0013] The push rod of the utility model is connected to the sliding rod through a universal joint, so even if the part is eccentric, it is not easy to cause torque, ensuring that the push rod can move up and down smoothly, and then smoothly adjust the position of the turbid and clear distribution plate. Because the push rod and the sliding rod are connected through a universal joint, and the sliding rod is hinged to the connecting rod, the position of the perforation on the end plate of the fixed frame remains unchanged, thereby facilitating the installation of the sealing assembly, thereby achieving the independence of the atmospheric zone and the turbid and filtrate zone, and avoiding cross-zone.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The outer frame 1, the fixed frame 2 and other structures of the distribution device are all prior arts, the same as patent document CN114931790B.

[0024] A circumferentially sliding turbid and clear distribution piece 3 is arranged in the fixed frame 2. The turbid and clear distribution piece 3 is hingedly connected to one end of the connecting rod 4. The other end of the connecting rod 4 is hingedly connected to the lower end of the sliding rod 5. The upper end of the sliding rod 5 is connected to one end of the push rod 7 through a universal joint 6. Through the setting of the universal joint 6, even if the sliding rod 5 and the push rod 7 are not in the same straight line, the push rod 7 can push the sliding rod 5 to move. A threaded section 8 is arranged at the other end of the push rod 7. The threaded section 8 passes through the upper end of the outer frame 1 and is screwed with an adjusting nut 9. By rotating the adjusting nut 9, the push rod 7 moves up and down. Through the up and down movement of the push rod 7, the turbid and clear distribution piece 3 is driven to move along the fixed frame 2 through the sliding rod 5 and the connecting rod 4, thereby adjusting the ratio of the clear filtrate area to the turbid filtrate area.

[0025] The method of using the distribution device is as follows: when the turbid filtrate area needs to be reduced, the adjusting nut 9 is rotated to move the push rod 7 upward, and the push rod 7 drives the sliding rod 5 and the connecting rod 4 to move upward, thereby driving the turbid and clear distribution piece 3 to move toward the side close to the turbid filtrate area, thereby reducing the space of the turbid filtrate area;

[0026] When the turbid filtrate area needs to be enlarged, the adjusting nut 9 is rotated to move the push rod 7 downward, and the push rod 7 drives the sliding rod 5 and the connecting rod 4 downward, thereby driving the turbid and clear distribution plate 3 to move away from the turbid filtrate area, thereby increasing the space of the turbid filtrate area.

[0027] like Figure 3-5As shown, a perforation is provided on the end plate of the fixed frame 2 near the turbid filtrate area, and a sealing assembly 10 is provided at the perforation. The sealing assembly 10 includes an annular T-shaped connecting plate 11, which is fixed to the perforation by bolts, and a sealing ring 12 is fixed inside the T-shaped connecting plate 11. The sliding rod 5 slides through the T-shaped connecting plate 11 and plays a sealing role through the sealing ring 12. Here, the separation of the turbid filtrate area and the atmosphere area is achieved by the setting of the sealing assembly 10, so as to avoid vacuum leakage in the turbid filtrate area and the occurrence of cross-area.

[0028] like Figure 4 and 6 As shown, the universal joint 6 includes a connecting seat and a universal ball 13, the connecting seat includes a lower connecting plate 14 and an upper connecting plate 15, the lower connecting plate 14 is fixed to the upper end of the sliding rod 5, the upper connecting plate 15 is detachably connected to the lower connecting plate 14 by bolts, the lower connecting plate 14 is provided with a lower arc groove 16 that cooperates with the lower side of the universal ball 13, the upper connecting plate 15 is provided with an upper arc groove 17 that cooperates with the upper side of the universal ball 13, the lower arc groove 16 and the upper arc groove 17 constitute an assembly groove for installing the universal ball 13, the universal ball 13 can rotate in multiple directions in the assembly groove, and the universal ball 13 is fixedly connected to the lower end of the push rod 7.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
