Description

Technical Field

[0001] The invention relates to the technical field of sludge drying, and in particular to a condensation prevention structure for a sludge drying bin wall. Background Art

[0002] With the continuous acceleration of urbanization and the development of modern industry, a huge amount of various types of urban domestic sludge and industrial sludge are produced every year around the world. For this reason, people have begun to seek some suitable process to effectively treat sludge. Sludge drying technology is a common technology that can effectively reduce the moisture content of sludge to facilitate its subsequent treatment. Specifically, it is a process of heating the sludge in specially designed equipment to evaporate the water in it. It can not only effectively remove the "free water" in the sludge, but also quickly evaporate the "interstitial water", "surface bound water" and even "internal bound water". Since this technology can dry the sludge to a specified moisture content according to the requirements of subsequent treatment procedures, it is widely used in existing sludge drying treatment.

[0003] When the dry sludge after sludge drying treatment enters the storage bin, there is still a certain amount of heat and moisture in the sludge, which causes the sludge to continue to release heat and water vapor, which not only easily leads to condensation on the inner wall of the storage bin, but also causes the sludge to become compacted in the storage bin, making it difficult to discharge the sludge from the storage bin. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a condensation prevention structure for the wall of a sludge drying silo, which solves the problem that condensation and compaction are easily caused when dry sludge enters a storage silo.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sludge drying silo wall anti-condensation structure, including a silo body, one side of the silo body is fixedly connected with inclined plates evenly distributed from top to bottom, the top of the inclined plates are fixedly connected with a first condensation plate, the silo body is fixedly connected with a second condensation plate evenly distributed from top to bottom between the inclined plates and the inner wall of the silo body, the side wall of the silo body adjacent to the second condensation plate is fixedly connected with a plurality of support plates, the bottom of the silo body adjacent to the second condensation plate is provided with a liquid collecting trough, the outer side wall of the bottom of the silo body is fixedly connected with a drain pipe, and the drain pipe and the liquid collecting trough are connected to each other.

[0008] Preferably, the bottom ends of the inclined plates extend obliquely downward, and the height of the bottom end of each inclined plate is equal to the height of the top end of the adjacent inclined plate below.

[0009] Preferably, the first condensing plates are all arranged vertically downward and are all arranged directly above the second condensing plates.

[0010] Preferably, the bottom ends of the second condensing plates are inclined and extend downward, and the inclination directions of the bottom ends of the inclined plate and the second condensing plates are opposite, the second condensing plates correspond one to one to the inclined plates, and the second condensing plates are arranged directly below the inclined plates, and the height of the top ends of the second condensing plates is higher than the height of the bottom ends of the adjacent inclined plates.

[0011] Preferably, the bottom ends of the second condensing plates are arranged directly above the liquid collecting tank.

[0012] Preferably, the support plate is fixedly connected to the first condensing plate and the second condensing plate.

[0013] Preferably, there are gaps between the bottom end of the first condensing plate and the second condensing plate, between the top end of the second condensing plate and the inclined plate, and between the bottom end of the second condensing plate and the inner wall of the bin body.

[0014] Working principle: After sludge drying treatment, the sludge enters the silo and falls on the inclined plate. The water vapor in the sludge overflows through the gap between the inclined plates. Since the temperature of the water vapor overflowing from the sludge is higher than the ambient temperature and there is a density difference between it and the ambient gas, the water vapor will move upward along the gap between the two adjacent inclined plates. When the water vapor contacts the first condensation plate and the second condensation plate, it will cool down and condense. After the condensate gathers into drops, it will first drip on the back of the second condensation plate, and then drip and gather in the collecting tank. The condensate in the collecting tank is then discharged from the silo through the drain pipe. This can prevent condensation on the inner wall of the silo, thereby preventing the sludge from hardening in the silo.

[0015] (III) Beneficial effects

[0016] The present invention provides a condensation prevention structure for the wall of a sludge drying silo, which has the following beneficial effects:

[0017] The present invention isolates the sludge entering the silo through the inclined plates, so that the water vapor generated by the sludge can overflow from the gaps in the inclined plates, and then the water vapor is cooled and condensed through the first condensation plate and the second condensation plate. The condensed liquid gathers into droplets and then drips into the liquid collecting tank and is discharged. In this way, condensation on the inner wall of the silo can be prevented, and the sludge can be prevented from being compacted, so that the sludge can be discharged from the silo more smoothly. It is worthy of vigorous promotion. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] like Figure 1-3 As shown, an embodiment of the present invention provides a condensation prevention structure for a sludge drying silo wall, including a silo body 4, a sloping plate 1 evenly distributed from top to bottom is fixedly connected to one side of the silo body 4, a first condensation plate 2 is fixedly connected to the top of each sloping plate 1, and a second condensation plate 3 evenly distributed from top to bottom is fixedly connected between the sloping plate 1 and the inner wall of the silo body 4 in the silo body 4. After the sludge drying treatment, the sludge enters the silo body 4 and falls on the sloping plate 1. The water vapor in the sludge can overflow through the gap between the sloping plates 1. When the water vapor contacts the first condensation plate 2 and the second condensation plate 3, it will be cooled and condensed. The condensed liquid gathers into drops and then drips onto the collecting The liquid is discharged from the silo 4 in the liquid tank 5, so that condensation can be prevented from occurring on the inner wall of the silo 4, thereby preventing the sludge from compacting in the silo 4, so that the sludge can be discharged from the silo 4 normally. A plurality of support plates 6 are fixedly connected to the side wall of the silo 4 adjacent to the second condensation plate 3, and the support plates 6 can reinforce the inclined plate 1, the first condensation plate 2 and the second condensation plate 3. A liquid collecting trough 5 is arranged at the bottom of the silo 4 adjacent to the second condensation plate 3, and a drain pipe 7 is fixedly connected to the outer wall of the bottom of the silo 4, and the drain pipe 7 is interconnected with the liquid collecting trough 5, and the condensate in the liquid collecting trough 5 can be discharged from the silo 4 through the drain pipe 7.

[0025] The bottom ends of the inclined plates 1 extend downwardly at an angle and the height of the bottom end of each inclined plate 1 is equal to the height of the top end of the adjacent inclined plate 1 below, so that the sludge in the bin body 4 is at the minimum repose angle, thereby preventing the sludge from overflowing from the top end of the inclined plate 1.

[0026] The first condensing plates 2 are all arranged vertically downward and are all arranged directly above the second condensing plates 3 .

[0027] The bottom ends of the second condensation plates 3 are inclined and extend downward, and the inclination directions of the bottom ends of the inclined plates 1 and the second condensation plates 3 are opposite.

The height of the top end of the second condensation plates 3 is higher than the height of the bottom end of the adjacent inclined plates 1. Since the temperature of the water vapor overflowing from the sludge is higher than the ambient temperature and there is a density difference between it and the ambient gas, the water vapor will move upward along the gap between the two adjacent inclined plates 1. When the water vapor contacts the first condensation plate 2 and the second condensation plate 3, it will be cooled and condensed.

[0028] The bottom ends of the second condensing plates 3 are arranged directly above the liquid collecting tank 5 . After the condensed liquid is gathered into drops, it will first drip onto the back side of the second condensing plates 3 , and then drip and collect into the liquid collecting tank 5 .

[0029] The support plate 6 is fixedly connected to the first condensing plate 2 and the second condensing plate 3 .

[0030] There are gaps between the bottom end of the first condensation plate 2 and the second condensation plate 3, between the top end of the second condensation plate 3 and the inclined plate 1, and between the bottom end of the second condensation plate 3 and the inner wall of the bin body 4. The gaps between the bottom end of the first condensation plate 2 and the second condensation plate 3, and between the top end of the second condensation plate 3 and the inclined plate 1 are for the movement of water vapor, and the gap between the bottom end of the second condensation plate 3 and the inner wall of the bin body 4 is for the condensate to drip into the liquid collecting tank 5.
