Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a wastewater treatment and reuse device for wastewater after co-firing sludge in a thermal power plant boiler. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or other energy with a certain amount of heat. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace. The hot water or steam produced in a boiler can directly provide the heat energy needed for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into hot water through a generator. Boilers that provide hot water are called hot water boilers, mainly used for domestic purposes, with some applications in industrial production. Boilers that produce steam are called steam boilers, often simply referred to as boilers. They are mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises. Generally, after thermal power plant boilers co-fire sludge, the wastewater inside needs to be recycled and treated to enable wastewater reuse, saving water resources and reducing costs.

[0003] Existing wastewater treatment devices typically use filtration equipment to filter sludge from wastewater. However, in actual operation, the filter screen inside the filtration device is easily clogged by sludge, making it inconvenient to use. Therefore, we propose a wastewater treatment and reuse device for sludge co-firing in thermal power plant boilers. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wastewater treatment and reuse device for sludge co-firing in thermal power plant boilers, so as to solve the problems existing in the background art.

[0009] Furthermore, the outer surface of the filter block is in contact with the inner side of the second rectangular groove, and the connecting and mounting sealing plate is in contact with the body of the recycling treatment equipment.

[0010] Furthermore, the buffer self-adjusting mechanism includes a fixed connecting block, which is fixedly connected to a connecting top block. A second fixed sleeve is fixedly connected to the bottom end of the fixed connecting block. A buffer spring is fixedly connected to the top end of the inner part of the second fixed sleeve.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1-5 This invention provides a wastewater treatment and reuse device for sludge co-firing in a thermal power plant boiler, comprising a reuse treatment device body 1, an inlet pipe 2 fixedly connected to one end of the reuse treatment device body 1, an outlet pipe 3 fixedly connected to the other end of the reuse treatment device body 1, a first rectangular groove 4 opened on the top of the reuse treatment device body 1, a second rectangular groove 5 opened on the front surface of the reuse treatment device body 1, a filter block 6 movably connected inside the reuse treatment device body 1, a connecting and mounting sealing plate 7 fixedly connected to one side of the filter block 6, a fixed connecting plate 8 fixedly connected to the surface of the connecting and mounting sealing plate 7, and a connecting and sealing mechanism 9 fixedly connected to the end of the reuse treatment device body 1.

[0023] The top of the sealing mechanism 9 is fixedly connected to a buffer self-adjusting mechanism 10, and the surface of the fixed connecting plate 8 is provided with a U-shaped limiting groove 11.

[0024] The connecting sealing mechanism 9 includes a first fixed sleeve 12, an electric telescopic rod 13 fixedly connected inside the first fixed sleeve 12, a connecting top block 14 fixedly connected to the top of the electric telescopic rod 13, a fixed connecting rod 15 fixedly connected to one side of the connecting top block 14, a fixed sleeve block 16 fixedly sleeved on the outer surface of the other end of the fixed connecting rod 15, a connecting mounting plate 17 fixedly connected to the bottom end of the fixed sleeve block 16, and a connecting sealing insert plate 18 fixedly connected to the bottom end of the connecting mounting plate 17. This allows the electric telescopic rod 13 to pull the connecting top block 14 downwards, causing the fixed connecting rod 15, the fixed sleeve block 16, the connecting mounting plate 17, and the connecting sealing insert plate 18 to move downwards. This allows the connecting sealing insert plate 18 to be inserted into the interior of the recycling treatment equipment body 1 through the first rectangular groove 4, thereby sealing the filter block 6. At this time, the filter block 6 can be pulled outwards to clean the sludge collected inside the filter block 6, making the operation convenient.

[0025] The outer surface of the connecting sealing plate 18 is in contact with the inner surface of the first rectangular groove 4, and the surface of the connecting sealing plate 18 is in contact with the end of the filter block 6, so that the connecting sealing plate 18 can move stably inside the first rectangular groove 4 and seal the surface of the filter block 6.

[0026] The outer surface of the filter block 6 is in contact with the inner surface of the second rectangular groove 5, and the connecting and mounting sealing plate 7 is in contact with the body of the recycling treatment equipment 1, so that the filter block 6 can move stably inside the second rectangular groove 5. The connecting and mounting sealing plate 7 can be in a sealed state with the body of the recycling treatment equipment 1.

[0027] The buffer self-adjusting mechanism 10 includes a fixed connecting block 20, which is fixedly connected to the connecting top block 14. A second fixed sleeve 21 is fixedly connected to the bottom end of the fixed connecting block 20. A buffer spring 22 is fixedly connected to the top end of the inner part of the second fixed sleeve 21. A force-bearing mounting plate 23 is fixedly connected to the bottom end of the buffer spring 22. A movable mounting rod 24 is fixedly connected to the bottom end of the force-bearing mounting plate 23. A fixed connecting bottom block 25 is fixedly connected to the bottom end of the movable mounting rod 24. A connecting limit rod 26 is fixedly connected to one side of the fixed connecting bottom block 25, facilitating the fixed connecting block 20 to follow the connecting top block 14. Moving downwards causes the second fixed sleeve 21, buffer spring 22, force-bearing mounting plate 23, movable mounting rod 24, fixed connecting bottom block 25, and connecting limit rod 26 to move downwards, allowing the connecting limit rod 26 to disengage from the inside of the U-shaped limit groove 11. When the fixed connecting bottom block 25 contacts the ground, the connecting sealing insert 18 has not yet moved into place, and the connecting top block 14 can continue to move downwards, causing the second fixed sleeve 21 to move. This allows the buffer spring 22 to contract at the top of the force-bearing mounting plate 23 and inside the second fixed sleeve 21, thus providing cushioning. The operation is convenient.

[0028] The outer surface of the connecting limit rod 26 fits into the inner side of the U-shaped limit groove 11, which makes it easy for the connecting limit rod 26 to be stably positioned inside the U-shaped limit groove 11 to fix the position of the fixed connecting plate 8, thereby fixing the position of the connecting and installing sealing plate 7 and filter block 6. The operation is convenient and quick.

[0029] The working principle of this invention is as follows: During use, the electric telescopic rod 13 pulls the connecting top block 14 downward, causing the fixed connecting rod 15, fixed sleeve block 16, connecting mounting plate 17, and connecting sealing insert plate 18 to move downward. Simultaneously, the fixed connecting block 20 moves downward with the connecting top block 14, causing the second fixed sleeve 21, buffer spring 22, force-bearing mounting plate 23, movable mounting rod 24, fixed connecting bottom block 25, and connecting limiting rod 26 to move downward. This allows the connecting limiting rod 26 to disengage from the inside of the U-shaped limiting groove 11. When the fixed connecting bottom block 25 contacts the ground, the connecting sealing insert plate 18 has not yet... Once in position, the connecting top block 14 can continuously move downwards, driving the second fixed sleeve 21 to move, so that the buffer spring 22 can retract at the top of the force-bearing mounting plate 23 and inside the second fixed sleeve 21. When the connecting sealing plate 18 can be inserted into the interior of the recycling treatment equipment body 1 through the first rectangular groove 4 to seal the interior of the recycling treatment equipment body 1, the connecting limit rod 26 disengages from the inside of the U-shaped limit slot 11. At this time, the fixed connecting plate 8 is pulled, driving the connecting mounting sealing plate 7 and the filter block 6 to move, disassembling the filter block 6, thereby cleaning the sludge inside the filter block 6, which is convenient to operate.
