Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and in particular relates to a sludge conveying device with an anti-splashing function. Background Art

[0002] In the subsequent process of sewage treatment, the sludge with a high water content is directly transferred to the upper part of the transfer vehicle through the screw conveyor, and finally squeezed out from the end and dropped into the carriage. Considering the convenience of the transfer vehicle in and out, the end of the conveyor should be higher than the highest point of the carriage. In addition to the height of the interior of the carriage, the sludge falls vertically from the end of the conveyor port into the carriage. The sludge falls at a height of about 3m, which makes the sludge fall freely too fast and easily splashes. It can even fly out of the carriage and splash onto the walls of the workshop, equipment, and passing maintenance personnel. On the one hand, it does not meet environmental protection requirements, and on the other hand, it is not conducive to on-site management, and even aggravates equipment corrosion and endangers the safety of passing maintenance personnel. In response to this problem, the general method of regularly stopping the sludge transfer related equipment and timely cleaning the sludge on the walls and equipment is adopted. This not only increases the workload of cleaning, but also there are risks in cleaning at high places, and it also affects the safe and stable operation of the equipment. Utility Model Content

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0022] Example

[0023] like Figures 1 to 4 As shown, the sludge conveying device with splash-proof function of the utility model comprises a screw conveyor 1 and a guide assembly 2. The input end of the screw conveyor 1 is respectively connected to a sludge dewatering room 100 and a plurality of sludge dewatering machines 200 to realize the collection of dewatered sludge. After the sewage is treated, a mud-water mixture is obtained. The mud-water mixture enters the sludge dewatering machine 200. After the water is filtered out by centrifugal action, sludge with a water content of about 80% is obtained. The sewage is collected and reprocessed, and the sludge is conveyed to the screw conveyor 1, and finally slowly conveyed to the end of the screw conveyor 1 and falls into the transport vehicle 400. The output end of the screw conveyor 1 is connected to the input end of the guide component 2, and the output end of the guide component 2 extends into the carriage of the transport vehicle 400. The dewatered sludge flows through the screw conveyor 1 and the guide component 2 in sequence and then enters the transport vehicle 400. The output end of the guide component 2 can be rotated to reduce the height of the sludge free fall and change the angle at which the sludge falls into the transport vehicle 400 to prevent the sludge from splashing.

[0024] In this embodiment, the input end of the screw conveyor 1 is respectively connected to the sludge dewatering room 100 and multiple sludge dewatering machines 200 to realize the collection of dewatered sludge, and the output end of the screw conveyor 1 is connected to the input end of the diversion component 2, and the output end of the diversion component 2 is facing the transport vehicle 400. The dewatered sludge flows through the screw conveyor 1 and the diversion component 2 in turn and then enters the transport vehicle 400. At the same time, the output end of the diversion component 2 can be rotated. By rotating the output end of the diversion component 2 to a suitable position, the movement direction of the sludge and the angle of falling into the transport vehicle are changed to reduce the height of the sludge free fall, effectively slowing down the speed of the sludge when it descends, preventing the sludge from splashing, fundamentally solving the problem of sludge splashing, and improving the cleanliness and safety of sludge transportation.

[0025] like Figure 2 As shown, the guide assembly 2 includes a first guide cylinder 21 and a second guide cylinder 22. The first guide cylinder 21 and the second guide cylinder 22 both adopt a square structure. The first guide cylinder 21 is arranged in the vertical direction. The top of the first guide cylinder 21 is fixedly connected to the output end of the screw conveyor 1 to realize the dewatered sludge being guided into the guide assembly 2. The bottom end of the first guide cylinder 21 is hinged to the second guide cylinder 22. The second guide cylinder 22 is rotated to change the angle between the first guide cylinder 21 and the second guide cylinder 22, change the movement direction of the sludge, and then change the angle at which the sludge falls into the transport vehicle 400 to prevent the sludge from splashing.

[0026] like Figure 3 and Figure 4 As shown, in this embodiment, the screw conveyor 1 adopts a shaftless screw conveyor, and a motor 11 is provided at the end of the screw conveyor 1. The top end of the first guide cylinder 21 is welded and fixed to the output end of the screw conveyor 1, which has the advantages of simple structure and reliable connection, and realizes a stable connection between the guide component 2 and the screw conveyor 1.

[0027] In this embodiment, the width of the second guide tube 22 is slightly larger than the width of the first guide tube 21. When the second guide tube 22 rotates, the bottom of the first guide tube 21 is wrapped inside the end of the second guide tube 22 to prevent sludge from splashing out from the connection between the first guide tube 21 and the second guide tube 22.

[0028] like Figure 2 As shown, a connecting pin 23 is provided at the hinged joint between the first guide tube 21 and the second guide tube 22 , and the second guide tube 22 rotates in the vertical direction around the connecting pin 23 .

[0029] like Figure 2As shown, a reinforcing rib 24 is provided around the outer side of the second guide tube 22, and the reinforcing rib 24 is close to the sludge outlet of the second guide tube 22. A pair of lifting ears 25 are provided on the reinforcing rib 24, and the lifting ears 25 are connected to the lifting assembly. The lifting assembly drives the lifting ears 25 to rise and fall, so as to realize the second guide tube 22 to rotate in the vertical direction around the connecting pin 23.

[0030] Furthermore, the second guide cylinder 22 rotates around the connecting pin 23 in the vertical direction at an angle of 0° to 90°. When the transport vehicle 400 enters and exits the sludge discharge bin 300, the second guide cylinder 22 is horizontal, and the second guide cylinder 22 and the first guide cylinder 21 are perpendicular to each other, which is convenient for the vehicle to enter and exit. After the vehicle is parked, the second guide cylinder 22 rotates to a certain angle and starts to transport the sludge.

[0031] Specifically, the lifting component can adopt a manual hoist or an electric hoist or a manual chain or an electric chain. The fulcrum of the lifting component is set on the top of the mud discharge bin 300 or the upper part of the first guide tube 21. When the lifting component is in operation, it only needs to drive the second guide tube 22 to rotate.

[0032] Although the utility model is disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the utility model without departing from the spirit and technical solution of the utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of protection of the technical solution of the utility model.
