Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vertical sludge dryer, mainly to solve the problem that the sludge cannot be added to the reactor at a uniform speed before the sludge is dried in the reactor, so that the sludge is much For one-time heating and drying, the sludge treatment time is increased, resulting in the inability to guarantee the dryness of the sludge and affecting the sludge treatment.

Embodiment 1

[0032] refer to Figure 1-Figure 5 , a vertical sludge dryer, including a bottom plate 6 and a reactor 1, the inner wall of the reactor 1 is provided with a nano-coating, thereby solving the problem of drying highly viscous sludge, and the outer surface of the reactor 1 is socketed There is a shell 101, and an oil-conducting layer is arranged between the shell 101 and the reactor 1. The top of the reactor 1 is fixed with a cover 102 by bolts. The top of the cover 102 is inserted with a feed pipe 103. The inner wall of the reactor 1 is The top of the top is fixed with a filter plate 303 and the first conical plate 4 by bolts, and the sludge falls on the filter plate 303 for filtering, and the solid particle impurities contained in the sludge are filtered, and the filter plate 303 and the first conical plate 4 is set up and down, the upper surface of the first cone-shaped plate 4 is provided with a feeding port 401, the upper surface of the cover body 102 is fixed with a support...

Embodiment 2

[0037] refer to Figure 6-Figure 7 , a vertical sludge dryer, including one end of the feed pipe 103 connected with a feed hopper 14 through a flange, the inner wall of one side of the feed hopper 14 is fixed with a baffle 1401 by bolts, and the top of the bottom plate 6 is fixed by bolts There is a liquid collection tank 13, one side of the liquid collection tank 13 is plugged with a fixed pipe 1402, and the top of the fixed pipe 1402 is provided with a water filter layer 1403, and in the sludge conveying hopper 14, the sludge will be received by the baffle 1401 Part of the moisture in the sludge is squeezed out, and the squeezed water falls into the fixed pipe 1402 after being filtered by the filter water layer 1403, and finally falls into the liquid collection tank 13 for centralized collection.

[0038] The working principle of this embodiment: when in use, the sludge is conveyed from the feed hopper 14, and in the feed hopper 14, the sludge is squeezed by the baffle 1401,...

Abstract

The invention relates to the technical field of sludge drying machines, and discloses a vertical sludge drying machine which comprises a bottom plate and a reaction kettle; the outer surface of the reaction kettle is sleeved with a shell, an oil guide layer is arranged between the shell and the reaction kettle, the top of the reaction kettle is fixedly connected with a cover body, and a feeding pipe is inserted into the top of the cover body; a filter plate and a first conical plate are fixedly connected to the top of the circumferential inner wall of the reaction kettle, the filter plate and the first conical plate are arranged up and down, and a discharging opening is formed in the upper surface of the first conical plate; a supporting column is fixedly connected to the upper surface of the cover body, a C-shaped base is fixedly connected to the top of the supporting column, and a motor is fixedly connected to one side of the C-shaped base; and one end of an output shaft of the motor is fixedly connected with a longitudinal bevel gear. According to the vertical sludge drying machine, the discharging opening can be indirectly opposite to a material passing opening, so that sludge can be conveyed at a constant speed, sludge drying in the later period is facilitated, and the dryness of the sludge is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sludge dryers, in particular to a vertical sludge dryer. Background technique [0002] The existing paddle dryer has a certain processing capacity requirement, and it is not economical to treat a small amount of dispersed sludge. The sludge treatment of highly polluting volatiles will cause secondary pollution to the surrounding air. The efficiency of the low-temperature dryer is low, and the volatile During the process of condensation, the heat loss is too large, the energy efficiency ratio is low, the unnecessary heat transfer area of ​​the drum and disc dryers is large, and the heat utilization rate is low, so a vertical sludge dryer is designed. [0003] At present, most of the existing sludge dryers have the following deficiencies: Before the sludge is dried by the reactor, the sludge cannot be added to the reactor at a uniform speed, so that the sludge is mostly heated and dried at one time, increas...
