Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically a sludge dewatering and conveying device. Background Technology

[0002] With the expansion of urban construction, more and more fertile land is being filled in for commercial use. The filling method directly leads to the waste of silt suitable for planting in the fertile land. In order to facilitate the transportation of silt, it is necessary to dehydrate the silt first.

[0003] An existing sludge dewatering and conveying device simply dumps the sludge onto a conveyor belt and dewaters it during transport by draining. However, this method results in slow draining due to sludge accumulation and low dewatering efficiency. Therefore, this application designs a sludge dewatering and conveying device that can level the sludge during transport, quickly thinning it to facilitate sludge-water exchange, and simultaneously use a dryer to dry it, accelerating the dewatering process.

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure will not be enlarged to scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] This utility model provides a sludge dewatering and conveying device. Sludge is fed into the feeding port and falls above the conveyor belt. A fan blows air onto the heating wire, and the hot airflow dries and dewaters the scraped sludge. By rotating the threaded rod, the height of the threaded block and the scraper can be adjusted to scrape out sludge of different thicknesses, which facilitates uniform heating of the sludge. Thinner sludge is easier to dewater. After being divided by the toothed groove, the dewatering area is increased, making it easier for the dried sludge to break off from the conveyor belt and be unloaded.

[0029] Figures 1-3 The diagram shown is a structural schematic of one embodiment of the sludge dewatering and conveying device of this utility model. Please refer to [link / reference]. Figures 1-3 The sludge dewatering and conveying device of this embodiment includes a sludge feeding mechanism 100, a protective cover 200, a sludge scraping mechanism 300, and a receiving hopper 400.

[0030] The mud feeding mechanism 100 conveys the sludge to the bottom of the drying component 220 via a transmission belt, and then to the receiving hopper 400. The pallet 120 supports the upper surface of the conveyor belt 110 to maintain stability and prevent collapse. The motor 130 controls the knocking rod 140 to rotate, so that the knocking rod 140 shakes off the sludge debris attached to the surface of the conveyor belt 110 and drops it into the receiving hopper 400. Specifically, the mud feeding mechanism 100 includes a conveyor belt 110, a pallet 120 set at the bottom of the upper layer of the conveyor belt 110, a motor 130 set on the side wall of the pallet 120, and a knocking rod 140 set at the output end of the motor 130.

[0031] The protective cover 200 feeds sludge into the feed port 210, which falls above the conveyor belt 110. The blower 221 blows air onto the heating wire, and the hot airflow dries and dehydrates the sludge after it has been leveled. Specifically, the protective cover 200 is located on the outer periphery of the conveyor belt 110. The side wall drying component 220 of the protective cover 200 includes a heating wire and a blower 221 that blows air onto the heating wire. The outlet of the blower 221 is located above the leveled sludge. The bottom of the protective cover 200 is provided with a cleaning port 201, and a door is provided at the opening of the cleaning port 201. The top of the protective cover 200 is provided with a feed port 210, and a regulating valve is provided inside the feed port 210.

[0032] The sludge scraping mechanism 300 can scrape out sludge of different thicknesses by rotating the threaded rod 320 and adjusting the height of the threaded block 330 and the scraper 340. This facilitates uniform heating of the sludge, and the thinner sludge is easier to dehydrate. After being divided by the toothed groove, the dehydration area is increased, making it easier to split off from the conveyor belt 110 after drying, which is convenient for unloading. Specifically, the sludge scraping mechanism 300 spreads the sludge evenly on the upper surface of the conveyor belt 110. In this embodiment, the sludge scraping mechanism 300 includes a guide rail 310, a threaded rod 320 disposed on the side wall of the guide rail 310, a threaded block 330 that cooperates with the threaded rod 320, and a scraper 340 disposed on the side wall of the threaded block 330. A handwheel 321 is provided at the top of the threaded rod 320, and a toothed groove is provided at the bottom of the scraper 340.

[0033] The receiving hopper 400 catches the dewatered sludge. In this embodiment, the bottom of the receiving hopper 400 is provided with a moving wheel, and the receiving hopper 400 is located below the end of the conveyor belt 110.

[0034] Combination Figures 1-3 The sludge dewatering and conveying device of this embodiment is used as follows: the sludge is conveyed to the area below the drying component 220 via a transmission belt, and then to the receiving hopper 400. The pallet 120 supports the upper surface of the conveyor belt 110 to maintain stability and prevent collapse. The motor 130 controls the knocking rod 140 to rotate, causing the knocking rod 140 to shake off the sludge debris attached to the surface of the conveyor belt 110 and drop it into the receiving hopper 400. The sludge is then fed into the feeding port 210 and falls above the conveyor belt 110. The fan 221 blows air onto the heating wire, and the hot airflow dries and dewaters the scraped sludge. By rotating the threaded rod 320 and adjusting the height of the threaded block 330 and the scraper 340, sludge of different thicknesses can be scraped out, which facilitates uniform heating of the sludge. The thinner sludge is easier to dewater. After being divided by the toothed groove, the dewatering area is increased, making it easier for the dried sludge to break off from the conveyor belt 110 and be unloaded.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
