Description

Chemical sludge drying device

Technical Field

The utility model relates to a chemical sludge drying device belongs to chemical sludge treatment equipment field.

Background

Chemical sludge is a product after sewage treatment, contains a large amount of organic matters, has chemical properties of easy decay, can emit strong foul gas, and is easy to breed parasitic ova and pathogenic microorganisms without treatment.

The chemical sludge drying device is one of the important devices for chemical sludge treatment, and because the chemical sludge contains more moisture, the existing chemical sludge drying device has large energy consumption and low drying efficiency when drying the chemical sludge.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: provides a chemical sludge drying device with low energy consumption and high drying efficiency.

Chemical industry sludge drying device, which comprises an upper housing, the last casing internal fixation has a sieve section of thick bamboo, the last internal rotation of epitheca is connected with the last pivot that runs through a sieve section of thick bamboo, it has last motor to go up the pivot coupling, be fixed with helical blade on the lateral wall of going up the pivot, it has the dog to go up the cover in the pivot, be fixed with the spring between dog and the last casing, the top of going up the casing is equipped with the feed inlet, the bottom of going up the casing is equipped with and sieves a corresponding ponding storehouse and the material passageway corresponding with the dog, be equipped with the outlet on the ponding storehouse, the below of going up the casing is fixed with the lower casing with the material passageway intercommunication, the internal rotation of inferior valve is connected with down the pivot, the lower pivot coupling has down the motor, be fixed with down helical blade on the lateral wall.

A plurality of crushing teeth are fixed on the inner side wall of the material channel, and can disperse the agglomerated sludge, thereby being beneficial to drying the sludge.

The bottom of foretell ponding storehouse is equipped with the water conservancy diversion piece, the drainage of being convenient for.

Compared with the prior art, the utility model beneficial effect who has is:

chemical industry sludge drying device, can extrude a large amount of moisture that contains in the mud in advance, then carry out the mummification through the heat again, not only reduced energy resource consumption, drying efficiency is higher moreover.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. an upper motor; 2. an upper rotating shaft; 3. a feed inlet; 4. an upper helical blade; 5. an upper housing; 6. a screen cylinder; 7. a water outlet; 8. a stopper; 9. a spring; 10. a flow guide block; 11. a water accumulation bin; 12. crushing teeth; 13. a material channel; 14. a thermal medium inlet; 15. a lower motor; 16. a lower rotating shaft; 17. a lower helical blade; 18. a lower housing; 19. a discharge port; 20. and a heat medium outlet.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings:

as shown in figure 1, the chemical sludge drying device comprises an upper shell 5, a screen drum 6 is fixed in the upper shell 5, an upper rotating shaft 2 which runs through the screen drum 6 is connected in the upper shell 5 in a rotating manner, an upper motor 1 is connected with the upper rotating shaft 2, an upper helical blade 4 is fixed on the outer side wall of the upper rotating shaft 2, a stop dog 8 is sleeved on the upper rotating shaft 2, a spring 9 is fixed between the stop dog 8 and the upper shell 5, a feed inlet 3 is arranged at the top of the upper shell 5, a water accumulation bin 11 corresponding to the screen drum 6 and a material channel 13 corresponding to the stop dog 8 are arranged at the bottom of the upper shell 5, a water outlet 7 is arranged on the water accumulation bin 11, a lower shell 18 which is communicated with the material channel 13 is fixed below the upper shell 5, a lower rotating shaft 16 is connected in the lower shell 18 in a rotating manner, a lower motor 15 is connected with the lower rotating shaft 16, a lower helical blade 17 is fixed on the outer side wall, A heat medium outlet 20 and a discharge port 19.

In a preferred embodiment: a plurality of crushing teeth 12 are fixed on the inner side wall of the material channel 13, so that agglomerated sludge can be dispersed, and drying of the sludge is facilitated; the bottom of the water accumulating bin 11 is provided with a flow guide block 10 for facilitating water drainage.

When the sludge drying device is used, sludge raw materials enter the upper shell 5 from the feeding hole 3, the sludge raw materials are conveyed to the stop block 8 under the action of the upper motor 1, the upper rotating shaft 2 and the upper spiral blade 4, the sludge is extruded at the stop block 8 due to the action of the spring 9, a large amount of moisture enters the water accumulating bin 11 from the screen drum 6 and is discharged through the water outlet 7, after the sludge is extruded at the stop block 8 by a certain amount, the thrust of the upper spiral blade 4 to the sludge overcomes the elastic force of the spring 9, the stop block 8 moves rightwards, so that the dewatered sludge enters the lower shell 18 through the material channel 13, the sludge is conveyed to the discharge hole 19 and is discharged under the action of the lower motor 15, the lower rotating shaft 16 and the lower spiral blade 17, and in the conveying process of the sludge, a heat medium enters the lower shell 18 from the heat medium inlet 14 and is dried to treat the.
