Description

Technical Field

[0001] The utility model relates to the technical field of sludge and waste liquid treatment, and particularly relates to a sludge and waste liquid hydrothermal hydrolysis device. Background Art

[0002] A large amount of organic pollutants, residual bacteria, nutrients and some macromolecular organic substances that are difficult to be decomposed are contained in sludge. If waste bacterial residues and other substances enter the anaerobic tank without treatment or after simple sedimentation, the above substances in the waste bacterial residues will cause harm to anaerobic bacteria, thereby prolonging the anaerobic treatment time, affecting the anaerobic treatment effect, and increasing the difficulty of subsequent biochemical treatment. Therefore, before entering the anaerobic tank, it is necessary to treat the sludge through a hydrothermal hydrolysis device.

[0003] In order to ensure the effect of hydrothermal hydrolysis, the existing hydrothermal hydrolysis device often stirs the waste liquid. However, the stirring blades of the existing stirring device all rotate in the same direction along with the driving shaft of the driving motor, so that the dispersion degree of the internal waste liquid is relatively low, resulting in uneven and insufficient stirring, and thus the hydrothermal hydrolysis efficiency of the waste liquid is low. For this reason, we propose a sludge and waste liquid hydrothermal hydrolysis device. Content of the Utility Model

[0004] In view of the problems existing in the above-mentioned existing sludge and waste liquid hydrothermal hydrolysis device, the present utility model is proposed.

[0005] Therefore, the purpose of the present utility model is to provide a sludge and waste liquid hydrothermal hydrolysis device, which solves the problem that in order to ensure the effect of hydrothermal hydrolysis, the existing hydrothermal hydrolysis device often stirs the waste liquid. However, the stirring blades of the existing stirring device all rotate in the same direction along with the driving shaft of the driving motor, so that the dispersion degree of the internal waste liquid is relatively low, resulting in uneven and insufficient stirring, and thus the hydrothermal hydrolysis efficiency of the waste liquid is low.

Both the feed inlet and the discharge outlet are communicated with the inside of the tank body. A rotating rod is rotationally connected to the outer wall of the first vertical plate. The inside of the rotating rod is of a hollow structure, and the rotating connection end of the rotating rod and the first vertical plate is of an open structure. The other end of the rotating rod penetrates through the tank body and extends to the outside of the tank body. A steam inlet pipe is arranged on the outer wall of the first vertical plate. The steam inlet pipe is rotationally connected to the rotating rod and is communicated with the rotating rod.

[0022] An embodiment of the present utility model discloses a sludge and waste liquid hydrothermal hydrolysis device.

[0023] The present utility model provides a sludge and waste liquid hydrothermal hydrolysis device as Figures 1 - 3 shown, which includes a horizontal plate 1, a tank body 4 and a bottom plate 15. A first vertical plate 2 and a second vertical plate 3 are respectively provided on the horizontal plate 1. One side of the tank body 4 is an open structure. The opening of the tank body 4 is rotatably connected to the first vertical plate 2 through a bearing. The other end of the tank body 4 is rotatably connected to the second vertical plate 3 through a bearing. A feed inlet 5 and a discharge outlet 6 are respectively provided on the outer wall of the first vertical plate 2. Both the feed inlet 5 and the discharge outlet 6 are communicated with the inside of the tank body 4. A rotating rod 8 is rotatably connected to the outer wall of the first vertical plate 2. The inside of the rotating rod 8 is a hollow structure, and the rotating connection end of the rotating rod 8 and the first vertical plate 2 is an open structure. The other end of the rotating rod 8 penetrates through the tank body 4 and extends to the outside of the tank body 4. A steam inlet pipe 13 is provided on the outer wall of the first vertical plate 2. The steam inlet pipe 13 is rotatably connected to the rotating rod 8 and is communicated with the rotating rod 8. A plurality of stirring blades 18 are provided on the rotating rod 8 and a plurality of air outlet holes 19 are opened.

[0024] In a sludge and waste liquid hydrothermal hydrolysis device of the present utility model, a first bevel gear 7 is installed on the outer wall of the tank body 4. A second bevel gear 9 is fixedly connected to the penetrating end of the rotating rod 8. A mounting plate 10 is installed on the second vertical plate 3. A motor 11 is installed on the mounting plate 10. The output end of the motor 11 penetrates through the mounting plate 10 and is fixedly connected to a third bevel gear 12. The first bevel gear 7 and the second bevel gear 9 are both meshed with the third bevel gear 12. The rotation of the third bevel gear 12 can be driven by the operation of the motor 11. Since the first bevel gear 7 and the second bevel gear 9 are both meshed with the third bevel gear 12, the first bevel gear 7 and the second bevel gear 9 can be driven to rotate in opposite directions, so that the rotation directions of the rotating rod 8 and the tank body 4 are opposite, and thus the waste liquid inside the tank body 4 can be stirred better.

[0025] A sludge waste liquid hydrothermal hydrolysis device of the present utility model, a plurality of baffle plates 20 are arranged around the inner wall of the tank body 4, which can facilitate the stirring of the waste liquid.

[0026] A sludge waste liquid hydrothermal hydrolysis device of the present utility model, a support rod 16 is fixedly connected to the bottom plate 15, the bottom plate 15 is rotationally connected to the cross plate 1 through the support rod 16, an electric lifting rod 17 is installed on the top outer wall of the bottom plate 15, and the extending end of the electric lifting rod 17 is hinged to the bottom outer wall of the cross plate 1. After the hydrothermal hydrolysis is completed, the electric lifting rod 17 can be used to drive one side of the cross plate 1 to lift, so as to facilitate the complete discharge of the waste liquid inside the tank body 4.

[0027] A sludge waste liquid hydrothermal hydrolysis device of the present utility model, a rubber gasket 14 is adhered to the bottom outer wall of the bottom plate 15, and the rubber gasket 14 is matched with the bottom plate 15 in terms of size and structure, which can improve the friction between the bottom plate 15 and the contact surface, thereby improving the stability of the device during use.

[0028] A sludge waste liquid hydrothermal hydrolysis device of the present utility model, a plurality of through holes are formed in the stirring blade 18, which can not only reduce the stress area of the stirring blade 18 to prevent the stirring blade 18 from deforming and being damaged, but also further improve the fluidity of the waste liquid.

[0029] During use, the sludge waste liquid enters the inside of the tank body 4 through the feed port 5, and then the motor 11 is started to drive the third bevel gear 12 to rotate. Since the first bevel gear 7 and the second bevel gear 9 are both meshed with the third bevel gear 12, the first bevel gear 7 and the second bevel gear 9 can be driven to rotate in opposite directions, so that the rotation directions of the rotating rod 8 and the tank body 4 are opposite, and thus the waste liquid inside the tank body 4 can be better stirred. Then the steam inlet pipe 13 is opened, and high-temperature and high-pressure steam enters the inside of the rotating rod 8 and is ejected through the air outlet holes 19 to form small bubbles for hydrothermal hydrolysis of the sludge waste liquid. After the hydrothermal hydrolysis is completed, the electric lifting rod 17 is started to drive one side of the cross plate 1 to lift, and then the discharge port 6 is opened to completely discharge the waste liquid inside the tank body 4.

[0030] Only some exemplary embodiments of the present utility model are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
