EXAMPLE III

The embodiment optimizes the peripheral transmission sludge treatment machine provided by the first embodiment.

Wherein the sludge treatment mechanism adopts a sludge suction mechanism, namely the peripheral transmission sludge treatment machine is a peripheral transmission sludge suction machine.

As shown in fig. 1, the sludge suction mechanism includes a central sludge tank 15 disposed on a central pillar 21, a sludge collecting tank 14 disposed at the bottom of a working bridge 13, and a plurality of sludge suction pipes 16 connected to the bottom of the sludge collecting tank 14, wherein the sludge collecting tank 14 is communicated with the central sludge tank 15 through a siphon 12.

The central mud trough 15, the mud collecting trough 14, the mud sucking pipe 16, the siphon pipe 12 and the like, and the connection structure between the devices can all adopt the conventional structure in the field. Preferably, a bottom end of the suction pipe 16 is further provided with a scraper.

Further, a flow regulating valve 17 is arranged at a pipe orifice at the top end of each mud suction pipe 16, at least part of the flow regulating valves 17 are cone valves, each cone valve comprises a cone valve head 173 and an actuating mechanism for driving the cone valve head 173 to ascend and descend, each actuating mechanism comprises a driving hand wheel 171 and a transmission unit, the driving hand wheel 171 is arranged above the working bridge 13 and is located at a position suitable for being manually operated by a worker, and the driving hand wheel 171 is connected with the cone valve head 173 through the transmission unit.

The conical valve head 173 is tapered from top to bottom, and the actuator drives the conical valve head 173 to move up and down, so that the size of a sludge channel defined between the conical valve head 173 and the sludge suction pipe 16 can be adjusted, and the purpose of adjusting the flow rate of sludge is achieved. In one embodiment, the diameter of the top end of the conical valve head 173 is larger than the diameter of the top end nozzle of the dredge pipe 16, and the conical valve head 173 is adapted to be clamped at the top end nozzle of the dredge pipe 16. In another embodiment, as shown in FIG. 5, the diameter of the top end of the conical valve head 173 is smaller than the diameter of the top end nozzle of the suction pipe 16, so that the conical valve head 173 can extend into the suction pipe 16; further, an annular valve plate 1731 is formed by extending outward at the top end periphery of the conical valve head 173, the projection of the mud suction pipe 16 on the horizontal plane is located within the projection range of the annular valve plate 1731 on the horizontal plane, the top end nozzle of the mud suction pipe 16 can be blocked by the annular valve plate 1731 and the conical valve head 173, and when the conical valve head 173 is further lifted, mud suction can be started and the flow can be regulated, wherein the annular valve plate 1731 is preferably an annular valve plate 1731, and the diameter of the outer ring is larger than the diameter of the top end nozzle of the mud suction pipe 16. Of the two approaches described above, the latter approach can significantly increase the flow adjustment range.

In one embodiment, as shown in fig. 5, the transmission unit comprises a transmission screw 1741, a transmission nut 1742 and a hollow hand wheel shaft 172, the hand wheel shaft 172 is fixedly connected to the driving hand wheel 171, the transmission nut 1742 is fixedly installed at the bottom end of the hand wheel shaft 172 and is in threaded connection with the transmission screw 1741, and the conical valve head 173 is installed at the bottom end of the transmission screw 1741.

The hand wheel shaft 172 is coaxially connected with the driving hand wheel 171, and the two are preferably detachably and fixedly connected; the hand wheel shaft 172 is coaxially connected with a drive nut 1742, the drive nut 1742 is preferably accommodated in the hollow inner cavity of the hand wheel shaft 172; the transmission screw 1741 is preferably coaxially connected with the conical valve head 173, and the transmission screw 1741 and the conical valve head 173 are preferably detachably and fixedly connected; the detachable fastening means may be a conventional detachable connection structure, which is not exemplified here. When the hand wheel shaft 172 is driven to rotate by the driving hand wheel 171, the transmission screw 1742 can be rotated, and the transmission screw 1741 can be linearly moved based on the screw transmission between the transmission screw 1742 and the transmission screw 1741, so that the conical valve head 173 is driven to ascend and descend. The screw rod mechanism is adopted for transmission, so that the reliability and the precision of the drive of the conical valve head 173 can be ensured; by adopting the hollow hand wheel shaft 172, the screw rod can enter the hand wheel shaft 172, so that the vertical space required by the moving stroke of the screw rod can be obviously reduced, and the equipment height and the occupied space of the suction dredge are reduced.

Preferably, a guide sleeve 1743 is arranged in the sludge collecting groove 14, and the transmission screw 1741 is arranged on the guide sleeve 1743 in a penetrating manner, so that the stability of the linear motion of the transmission screw 1741 can be effectively improved; the guide sleeve 1743 may be a threaded sleeve or a smooth-walled guide sleeve (a polished rod segment may be correspondingly disposed on the drive screw 1741).

In one embodiment, the conical valve head 173 is connected to the drive unit via a universal joint, for example, the conical valve head 173 is connected to the drive screw 1741 via a universal joint. In actual use, the mud scraping plate at the bottom end of the mud suction pipe 16 needs to scrape mud at the bottom of the tank, and the mud suction pipe 16 can be subjected to certain mud resistance, so that the mud suction pipe 16 can loosen/vibrate for a long time; in addition, the sludge at the bottom of the sludge collecting tank 14 is also easily blocked between the conical valve head 173 and the top nozzle of the sludge suction pipe 16; in this embodiment, the conical valve head 173 is connected to the transmission unit via a universal joint, so that on one hand, the requirement for the alignment accuracy between the conical valve head 173 and the sludge suction pipe 16 can be reduced, and the top nozzle of the sludge suction pipe 16 can be reliably blocked when the conical valve head 173 is at a low position, and on the other hand, the conical valve head 173 and the actuator can be prevented from being adversely affected due to the vibration of the sludge suction pipe 16, and in addition, the blockage caused by the bottom sludge between the conical valve head 173 and the top nozzle of the sludge suction pipe 16 can be avoided. The above configuration is particularly suitable for the case where the diameter of the tip of the conical valve head 173 is larger than the diameter of the tip nozzle of the suction pipe 16.

In one embodiment, the taper of each of the tapered valve heads 173 increases from proximal to the central barrel to distal to the central barrel. For a sedimentation tank with water entering from the center, generally, the sludge is more sedimented closer to the center of the tank body 2; through the taper design, the larger the taper of the tapered valve head 173, the larger the sludge flow under the same valve height, so the actual sludge sedimentation condition can be better adapted.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
