It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Fig. 1 shows a sludge treatment device for chemical production of the utility model, which comprises:

the top of the body is provided with a body 1 of a mud feeding hopper 2, the inside of the body 1 is divided into a primary drying area 4 and a secondary drying area 5 by a partition plate 3, and a feed opening 6 for communicating the primary drying area 4 and the secondary drying area 5 is arranged between one side of the partition plate 3 and the side wall of the body 1;

a conveying assembly for conveying sludge is arranged in the primary drying area 4, one end of the conveying assembly is positioned below the sludge inlet hopper 2, a hot air pipe I7 is arranged on the top wall of the body 1, and a plurality of air spraying holes I71 are formed in the bottom of the hot air pipe I7;

the bottom is equipped with screen cloth 8 in

secondary drying zone

5, 8 one sides of screen cloth are equipped with

discharging pipe

9, 8 tops of screen cloth install with 17 output shaft of motor carry auger 16 the lower surface mounting of baffle 3 has two 10 hot-blast main, two 10 bottoms of hot-blast main are opened and are had two 11 in a plurality of wind-jet holes, 8 bottoms of screen cloth are equipped with three 13 of hot-blast main that the surface was opened and is had three 12 in wind-jet hole, hot-blast main 7, two 10 and three 13 of hot-blast main are connected through the air-out end of ventilation pipe 14 with air heater 15 respectively.

In the technical scheme, the primary drying zone 4 and the secondary drying zone 5 are matched together in the sludge treatment device, so that the sludge is dried and dried, the sludge is dried fully, the sludge dehumidification rate is improved, and the sludge drying efficiency is improved; hot air is sprayed out of the hot air pipe I7 of the primary drying area 4 to primarily dry the sludge, so that the drying pressure of the subsequent secondary drying area 5 is reduced; the arrangement of the filter screen 8 of the secondary drying zone 5 is convenient for hot air to dry the bottom of the sludge, so that the upper part and the bottom of the secondary drying zone 5 are both contacted with the hot air, the contact area of the sludge and the hot air is increased, and the sludge is comprehensively and fully dried; the sludge is turned over while the sludge is conveyed by the conveying auger 16, so that the sludge at the bottom is turned over to the top, the drying and dehumidifying comprehensiveness and the filling degree are improved, and the drying and drying efficiency of the sludge is improved.

The working principle is as follows: sludge to be dried enters a primary drying area 4 through a sludge inlet hopper 2, the sludge falls onto a conveying assembly, hot air is sprayed out through an air spraying hole I71 of a hot air pipe I7 to dry the sludge on the conveying assembly, the conveying assembly conveys the sludge above a material through hole 6, the sludge after primary drying falls into a secondary drying area 5 through the material through hole 6, the hot air is sprayed out through an air spraying hole II 11 of a hot air pipe II 10 and an air spraying hole 12 of a hot air pipe III 13 to further dry and dry the sludge on a screen 8, meanwhile, a motor I17 is started, a motor I17 drives a conveying auger 16 to rotate, the conveying auger 16 gradually conveys the sludge to a discharge pipe 9 while stirring the sludge, and the sludge after primary drying and secondary drying is finally discharged and collected through the discharge pipe 9.

In another example, a baffle 18 is vertically arranged downwards on one side of the partition plate 3 close to the material through opening 6, a crushing area 19 is formed by one side of the baffle 18 facing the material through opening 6 and the body 1, and a crushing roller set driven by a motor II is arranged in the crushing area 19 in a radial direction. By adopting the scheme, the motor II (not shown) drives the crushing roller group to work, so that the crushing roller group cuts and crushes the sludge falling from the material passing port 6, the contact area between the sludge falling into the secondary drying area 5 and hot air is increased, and the drying effect of the sludge is ensured; the setting of baffle 18 avoids mud to splash to the other end of secondary drying zone 5 and not receive secondary drying and directly discharge through discharging pipe 9 by the in-process of cutting, simultaneously because the mud that falls from logical material mouth 6 is the mud after primary drying, the water content in the mud reduces, does benefit to the crushing roller group to cut it and smashes.

In another example, the crushing roller group comprises two crushing rollers 20 which are oppositely arranged, the surface of each crushing roller 20 is annularly provided with a sharp knife 21, and a crushing gap is arranged between the crushing rollers 20. With this arrangement, the second motor (not shown) drives the crushing roller 20 to rotate, and the crushing roller 20 drives the sharp knife 21 to rotate so as to cut the dispersed sludge.

In another example, the conveying assembly comprises a driving wheel 22 in three-gear transmission connection with a motor, a driven wheel 23 and a belt 24, and the belt 24 is transversely wound between the driving wheel 22 and the driven wheel 23. With this arrangement, the belt 24 is allowed to stably transport the sludge.

In another example, a connecting rod 25 is vertically arranged on the top wall of the primary drying zone 4, a scraper 26 is arranged at the bottom of the connecting rod 25, the bottom surface of the scraper 26 is in surface contact with the belt 24, and the scraper 26 is positioned above the material passing opening 6. With this arrangement, the scraper 26 can scrape off sludge adhering to the belt 24, so that sludge falls off the belt 24, and a large amount of sludge is prevented from adhering to the belt 24.

In another example, the top of the body 1 is provided with an exhaust pipe 27, and the exhaust pipe 27 is connected with a filter. By adopting the scheme, water vapor generated in the drying process of the sludge is discharged through the exhaust pipe 27, the water vapor is prevented from accumulating in the body 1 to influence the drying operation, and the discharged gas is filtered by a filter (not shown) to remove harmful substances and is discharged.
