[0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from sludge through infiltration or evaporation. It generally refers to the use of self-evaporation facilities such as sludge drying plants. In the current existing technology, when the existing sludge is dried, the bottom of the sludge is less exposed to heat, resulting in the surface of the sludge being dried, but the bottom is still in a wet state, which affects the drying effect of the sludge.

[0003] In the prior art, the application number is CN202220384257.1, and the name is a sludge treatment and drying device, which discloses a sludge treatment and drying device, including a stirring tank; a fixed box is fixedly connected to the top of the stirring tank; a motor is fixedly connected to the inner wall of the fixed box; a rotating rod is fixedly connected to the output end of the motor; a plurality of stirring rods are fixedly connected to both ends of the rotating rod; a heating plate is fixedly connected to the inner wall of the stirring tank; by turning on the motor, the rotating rod is driven to rotate, and the rotating rod drives the stirring rod to rotate to stir the sludge, and the heating plate is used to continuously generate heat downward to dry the sludge. With the continuous stirring of the stirring rod, the sludge can be evenly heated in all directions to improve the drying effect of the sludge.

[0004] Although the above patent dries the sludge by stirring the sludge and cooperating with the heating plate to continuously generate heat downward, and with the continuous stirring of the stirring rod, the sludge can be evenly heated in all directions to improve the drying effect of the sludge, but because the hot air is only blown to the surface of the sludge, even if a stirring component is provided to assist, the sludge cannot be heated in all directions quickly, and the drying efficiency needs to be further improved. In view of this, the present utility model is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Reference Figure 1-Figure 3 A sludge treatment and drying device comprises: a sludge treatment tank 1; a feed funnel 102, fixedly connected to the feed port on one side of the sludge treatment tank 1; a first ventilation pipe 2, vertically rotatably connected to the middle position inside the sludge treatment tank 1; a first stirring hollow pipe 8, fixedly connected to the first ventilation pipe 2 at circumferentially equal intervals, wherein the first stirring hollow pipe 8 is provided with multiple rows and is connected to the first ventilation pipe 2; a hollow disc 4, fixedly connected to the upper end of the first ventilation pipe 2, and is connected to the first ventilation pipe 2; a second ventilation pipe 5, rotatably connected to the hollow disc 4 at circumferentially equal intervals, wherein the second ventilation pipe 5 is located at the hollow disc 4 A hollow convex ring 501 is provided at an inner position, and a circle of through holes is provided on the hollow convex ring 501; the second mixing hollow tube 9 is fixedly connected to the second ventilation tube 5 at equal intervals on the circumference, wherein the second mixing hollow tube 9 is provided with multiple rows and is connected to the second ventilation tube 5, and multiple ventilation ports are provided on the upper and lower sides of the first mixing hollow tube 8 and the second mixing hollow tube 9, and a one-way valve is provided in the ventilation port; a driving part for driving the first ventilation tube 2 and the second ventilation tube 5 to rotate is installed on the sludge treatment tank 1; a hot air blower 3 is installed on the sludge treatment tank 1, and the air outlet end is rotatably connected to the air inlet of the first ventilation tube 2 through a rotating joint;

[0024] The bottom of the sludge treatment tank 1 is open, and a sealing plate 11 is symmetrically rotated at the opening of the bottom of the sludge treatment tank 1. The two sides of the bottom of the sludge treatment tank 1 are symmetrically fixedly connected with leg plates 103. The sides of the two leg plates 103 close to each other are both rotatably connected with hydraulic telescopic columns 12, and the ends of the hydraulic telescopic columns 12 away from the leg plates 103 are rotatably connected to the adjacent sealing plates 11.

[0025] The driving part includes a driving motor 104, a ring gear 6 and a transmission gear 7. The driving motor 104 is fixedly connected to one side of the upper end of the sludge treatment tank 1. The output end of the driving motor 104 is fixedly connected to a first gear. The first ventilation pipe 2 is fixedly connected to a second gear meshing with the first gear. The upper end of the second ventilation pipe 5 passes through the hollow disc 4 upward and is fixedly connected to the transmission gear 7. The ring gear 6 is fixedly connected to the outside of the transmission gear 7 inside the sludge treatment tank 1 near the transmission gear 7 through a support rod and meshes with the transmission gear 7.

[0026] In the sewage treatment plant, after the sludge in the sewage is separated, the sludge can be transported into the sludge treatment tank 1 through the feed funnel 102. After a certain amount of sludge is added, the drive motor 104 and the hot air blower 3 are started at the same time. When the hot air blower 3 is working, hot air will be transported into the first ventilation pipe 2, and then the hot air will enter the first stirring hollow pipe 8 and the hollow disc 4. The hot air entering the hollow disc 4 will enter the second ventilation pipe 5 through the through hole on the hollow convex ring 501, and then enter the second stirring hollow pipe 8. In the core tube 9, when all the first stirring hollow tubes 8 and the second stirring hollow tubes 9 are filled with hot air and reach a certain pressure, the hot air will be sprayed into the sludge through the vents of the first stirring hollow tubes 8 and the second stirring hollow tubes 9, thereby heating the sludge to evaporate the moisture in the sludge. Since the first stirring hollow tubes 8 and the second stirring hollow tubes 9 are arranged in multiple rows, the sludge can be heated in multiple layers to fully heat the sludge and improve the heating effect of the sludge. The heated water vapor will be discharged through the feed funnel 102. When the driving motor 104 is working, it will drive the first gear to rotate, and the first gear will drive the first ventilation pipe 2 to rotate through the second gear. The first ventilation pipe 2 will drive the first stirring hollow pipe 8 to rotate, and the first ventilation pipe 2 will drive the hollow disc 4 to rotate at the same time, and then the hollow disc 4 will drive the second ventilation pipe 5 to rotate. Since the transmission gear 7 at the upper end of the second ventilation pipe 5 is meshed with the gear ring 6, the second ventilation pipe 5 drives the second stirring hollow pipe 9 to make a circle around the first ventilation pipe 2. While rotating, the second stirring hollow tube 9 will also be driven to rotate, and the first stirring hollow tube 8 and the second stirring hollow tube 9 are staggered, so that the sludge in the sludge treatment tank 1 can be fully stirred, so that the sludge can be fully in contact with the hot air, thereby improving the drying efficiency of the water in the sludge. When the sludge is heated and dried, the hydraulic telescopic column 12 is controlled to retract, and then the sealing plate 11 can be controlled to open, and then the dried sludge can fall into the sludge treatment tank 1 under the action of its own gravity.

[0027] Embodiment 2:

[0028] Reference Figure 1-Figure 3 , a sludge treatment and drying device, which is basically the same as Example 1, and further: an air inlet and an air outlet of the hot air blower 3 are respectively fixedly connected with an air intake pipe 301 and an air delivery pipe 302, the air delivery pipe 302 is connected to the air inlet of the first ventilation pipe 2 through a rotary joint, and the air intake of the air intake pipe 301 is close to the drive motor 104. By making the air intake end of the air intake pipe 301 close to the drive motor 104, when the hot air blower 3 inhales air through the air intake pipe 301, the flow rate of the air around the drive motor 104 can be accelerated, thereby achieving the effect of ventilation and heat dissipation of the drive motor 104, and improving the service life of the drive motor 104;

[0029] A circle of annular chute 101 is provided near the hollow disc 4 inside the sludge treatment tank 1, and the hollow disc 4 is slidably connected in the annular chute 101. Through the setting of the annular chute 101, the first ventilation pipe 2, the second ventilation pipe 5 and the first stirring hollow pipe 8 and the second stirring hollow pipe 9 can be limited by the hollow disc 4, thereby improving its stability when stirring the sludge;

[0030] A scraper 10 is fixedly connected to the bottom of the first ventilation pipe 2, and the scraper 10 is slidably connected to two sealing plates 11. By arranging the scraper 10 at the bottom of the first ventilation pipe 2, when the first ventilation pipe 2 rotates, the scraper 10 can be driven to scrape on the sealing plates 11, thereby preventing the sludge from adhering to the sealing plates 11 after drying, thereby causing part of the sludge to be unable to be discharged from the sludge treatment tank 1, thereby effectively ensuring the sludge discharge amount.

[0031] The utility model respectively arranges multiple rows of first stirring hollow tubes 8 and second stirring hollow tubes 9 on the first ventilation tube 2 and the second ventilation tube 5, so that hot air can be sprayed to positions of different depths in the sludge at the same time. Compared with the prior art, the sludge can be heated quickly and the drying effect of the sludge can be accelerated. The second stirring hollow tubes 9 can be made to rotate on themselves while rotating in a circle around the first ventilation tube 2, and the first stirring hollow tubes 8 and the second stirring hollow tubes 9 are staggered. Compared with the prior art, the sludge can be more fully contacted with the hot air, so that the sludge can be evenly heated in all directions, further accelerating the drying effect of the sludge.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model.
