Description

Technical Field

[0001] The utility model belongs to the technical field of fly ash solidification, and particularly relates to a fly ash solidification and stabilization treatment device. Background Art

[0002] At present, the implementation method for the solidification and stabilization of waste incineration fly ash is usually as follows: a curing agent, cement, and a stabilizer are added to the fly ash together, and the fly ash is stirred with the curing agent, cement, and stabilizer through a mixer for solidification treatment.

[0003] Currently, the fly ash and cement are uniformly mixed through a mixer. During the mixing process, a certain amount of curing agent and stabilizer need to be added to contact the fly ash to promote chemical reactions and accelerate the solidification of the fly ash. In order to achieve a better solidification effect of the fly ash, the operator needs to add a certain amount of curing agent or stabilizer according to the solidification situation of the fly ash. Since the dispersant is generally in 200L barrels and generally needs to be added multiple times per batch to achieve a better solidification effect, in the past, a manual measuring cylinder was used to fix the volume and add the curing agent or stabilizer. When manually operating the measuring cylinder to fix the volume, it was necessary to fix the volume through the measuring cylinder multiple times and then add it to the mixer, and the operation was relatively cumbersome and time-consuming, which was very inconvenient. Summary of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a fly ash curing and stabilizing treatment device as Figures 1-4 shown, including:

[0025] A curing box 1, with two groups of support legs 2 provided at the bottom of the curing box 1;

[0026] A feed barrel 3, which is provided at the top of the curing box 1 and a weighing assembly for weighing the materials in the feed barrel 3 is provided at the bottom of the feed barrel 3. The materials in the feed barrel 3 are weighed by the weighing instrument 4 of the weighing assembly, so that the cylinder 15 drives the sealing block 11 to move and the materials fall into the curing box 1;

[0027] The weighing assembly includes a blanking box 5, the weighing instrument 4 is provided on both sides at the bottom of the feed barrel 3, the blanking box 5 is connected to the feed barrel 3, a sleeve 6 is provided in the blanking box 5, a sliding rod 7 is slidably connected in the sleeve 6, one end of the sliding rod 7 located in the sleeve 6 is sleeved with a spring 8, and both ends of the spring 8 are fixedly connected to the sleeve 6 and the limit block 9 at the bottom of the sliding rod 7 respectively. A blanking port 10 is provided at the bottom of the feed barrel 3 and a sealing block 11 for sealing the blanking port 10 is provided in the blanking port 10.

[0028] The other end of the sliding rod 7 is fixedly connected to the sealing block 11. Fixed seats 12 are provided on both sides at the top of the curing box 1, and vertical rods 13 are provided on the tops of the fixed seats 12. The stability of the structure is strengthened by the vertical rods 13, so that the cylinder 15 works more stably.

[0029] The top of the vertical rod 13 is fixedly connected with a top plate 14. The cylinder 15 is arranged at the bottom of the top plate 14. The output shaft of the cylinder 15 is connected with the sealing block 11, and the output shaft of the cylinder 15 can drive the sealing block 11 to move.

[0030] Both sides of the bottom of the blanking box 5 are provided with openings 16, and the openings 16 are communicated with the slots at the top of the curing box 1. The fly ash, cement, curing agent and stabilizer entering the blanking box 5 can fall into the curing box 1 through the openings 16 on both sides of the bottom of the blanking box 5 through the communicated slots.

[0031] Two groups of rotating rods 17 are rotatably connected in the curing box 1. A plurality of mounting seats 18 are arranged on the surface of the rotating rod 17, and stirring blades 19 are arranged on the surface of the mounting seat 18. Two groups of motors 20 are arranged on the surface of the curing box 1. The output shaft of the motor 20 rotates through the curing box 1 and is fixedly connected with the rotating rod 17. When the motor 20 works, it can drive the rotating rod 17 to rotate, and stir and mix the fly ash in the curing box 1 through the stirring blades 19 on the surface of the rotating rod 17.

[0032] A discharge pipe 21 is arranged at the bottom of the curing box 1. After the fly ash is solidified, the fly ash in the curing box 1 can be discharged through the discharge pipe 21, and a control valve is arranged on the surface of the discharge pipe 21, and the opening or closing of the discharge pipe 21 can be controlled through the control valve.

[0033] For this fly ash solidification and stabilization treatment equipment, in the initial state, the sealing block 11 seals the material dropping port 10. At this time, when solidification operation is required, start the cylinder 15 to drive the sealing block 11 to disengage from the sealing of the material dropping port 10, and add fly ash and cement into the feeding bucket 3, so that the fly ash and cement enter the blanking box 5 through the material dropping port 10 at the bottom of the feeding bucket 3, and fall into the curing box 1 through the openings 16 at the bottom of the blanking box 5 for solidification. Then start the cylinder 15 again to drive the sealing block 11 to reset to the initial state, seal the material dropping port 10 through the sealing block 11, and stop the motor 20 from working. Add an appropriate amount of curing agent or stabilizer into the feeding bucket 3, weigh the curing agent or stabilizer in the feeding bucket 3 through the weighing instrument 4, and the weighed weight is displayed on the display screen on the surface of the curing box 1, which is convenient for the operator to observe the weight of the curing agent or stabilizer for feeding or reducing the material, so that the weight of the curing agent or stabilizer reaches the required weight. When the required weight is reached, control the cylinder 15 to work again. The output shaft of the cylinder 15 extends downward and pushes the sealing block 11 in the material dropping port 10 to move in the direction close to the sleeve 6. While the sealing block 11 moves, the bottom sliding rod 7 slides into the sleeve 6, guides the moving direction of the sealing block 11 to enhance the stability of the movement of the sealing block 11, and the material dropping port 10 is opened by the movement of the sealing block 11;

[0034] At this time, the curing agent or stabilizer located in the feeding barrel 3 enters the blanking box 5 through the blanking port 10 and falls into the curing box 1 from the openings 16 on both sides of the bottom of the blanking box 5. When all the curing agent or stabilizer in the feeding barrel 3 has fallen into the blanking box 5, control the air cylinder 15 to drive the sealing block 11 to reset to the initial state, and continue to seal the blanking port 10. Start the two groups of motors 20 to work again. The motor 20 drives the rotating rod 17 to rotate, so as to fully mix the fly ash, cement, curing agent and stabilizer in the curing box 1 through the stirring blades 19 on the surface of the rotating rod 17, thereby greatly improving the effect of fly ash curing. After the fly ash is cured, the fly ash in the curing box 1 can be discharged through the discharge pipe 21. Since the fly ash and cement have poor fluidity and may cause blockage when falling through the blanking port 10 and the opening 16, the output shaft of the air cylinder 15 can be controlled to extend or retract, so as to drive the sealing block 11 to move in the blanking port 10 and dredge the blocked fly ash and cement in the blanking port 10. At the same time, when the sealing block 11 moves, it will drive the dredging rods 22 arranged on both sides to move, so that the dredging rods 22 move up and down back and forth in the opening 16 to dredge the blocked fly ash and cement in the opening 16, thus avoiding the problem of blockage during blanking.

[0035] For the present utility model, the motor 20 and the air cylinder 15 can be manually adjusted by corresponding connection switch buttons, such as the switch for controlling the forward and reverse rotation of the motor 20 and the switch for controlling the extension or retraction of the air cylinder 15. It can also adopt intelligent control, such as connecting to Siemens PLC or single-chip microcomputer STM32 for control. Since these are all existing control technologies, they will not be elaborated here.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
