[0029] Reference Figure 1-4 As shown, this utility model provides a technical solution for preparing an adsorbent and passivating agent for detoxifying fly ash from waste incineration:

[0030] A device for preparing an adsorbent and passivating agent for detoxifying fly ash from waste incineration includes a box body 1 with an opening at the top and a main sliding port 11 on the left side wall of the box body 1. A through inclined groove block 32 is slidably connected to the main sliding port 11. A receiving box body 3 is inclined downward to the through inclined groove block 32. The receiving box body 3 has an opening at the top and an inner box body 34 is placed inside the receiving box body 3. Several cone blocks 31 are provided on the inner bottom surface of the inner box body 34. An electric heating mesh 4 is provided on the outer bottom surface of the receiving box body 3 for heating the receiving box body 3. It should be noted that the electric heating mesh 4 is prior art, and its heating after being energized is prior art, which will not be described in detail here.

[0031] Reference Figure 1-4 As shown, it should be further explained that both the housing body 3 and the inner box body 34 have connecting ports at the through inclined block 32, which connect to the external environment. That is, when the inner box body 34 is placed inside the housing body 3, the connecting port on the inner box body 34 is aligned with the connecting port on the housing body 3, and both ends of the through inclined block 32 are open, with the bottom port aligned with the connecting port on the housing body 3.

[0032] Reference Figure 1-4 As shown, an intermittent lifting assembly is provided between the bottom surface of the through inclined slot block 32 at the main sliding port 11 and the bottom surface of the main sliding port 11. The intermittent lifting assembly includes a motor 5, a rotating shaft 51 and a convex ring sleeve 52.

[0033] Reference Figure 2-4 As shown, the device also includes an inner plate 21, a spring 22 and a cover plate 23. The cover plate 23 is used to cover the top of the housing 3. The top of the housing 1 is detachably and slidably connected to a top plate 2, which is used to hold the inner plate 21 against it.

[0034] It should be noted that the cover plate 23 is designed as an inverted convex shape, which is locked on the top of the housing 3 and the inner housing 34. The protruding part is located inside the inner housing 34, thereby preventing it from moving left and right and improving its stability.

[0035] It should be noted that sliding openings 13 are provided on the upper part of both the left and right side walls of the housing 1. The top plate 2 is slidably connected within the sliding openings 13. The spring 22 is fixedly connected between the inner plate 21 and the cover plate 23. A connector 14 is fixedly connected to the left side wall of the housing 1. The motor 5 is fixedly connected to the connector 14. The rotating shaft 51 is fixedly connected to the output end of the motor 5. The convex ring sleeve 52 is sleeved on the rotating shaft 51. Limiting side openings 12 are provided on both sides of the main sliding opening 11. Limiting sliders are provided on the side walls of the through inclined groove block 32 located at the main sliding opening 11 and close to the limiting side openings 12. 33, the limiting slider 33 is slidably connected inside the limiting side opening 12, the through inclined groove block 32 is set on the upper part of the left side wall of the housing 3, the through inclined groove block 32 connects the housing 3 and the external environment, the electric heating mesh 4 includes a wire 41 and a plug 42 for connecting to an external power source, the connector 14 includes an L-shaped fixing block and an arc-shaped fixing block, the convex ring sleeve 52 is rotatably connected to the L-shaped fixing block on the connector 14, the motor 5 is set on the arc-shaped fixing block on the connector 14, the wire 41 extends out of the inside of the housing 1 from the main sliding opening 11, and the sharp end of the cone block 31 is set upward.

[0036] This device, through the arrangement and cooperation of the housing 3, cone block 31, through inclined trough block 32, and intermittent lifting component, utilizes the up-and-down vibration of the housing 3 and inner box 34 to cause the attapulgite filter cake to move up and down within the inner box 34 and collide with the cone block 31, thus breaking it. This not only accelerates the drying process of the attapulgite filter cake but also avoids local overheating caused by its constant contact with the heating surface of the inner box 34, which would affect the adsorption performance of the structure. The repeated impact with the cone block 31 ensures that the attapulgite filter cake reaches the target particle size, realizing the simultaneous drying and grinding of the attapulgite filter cake. This greatly improves the preparation efficiency of the adsorbent from the attapulgite filter cake, and the structure is simple and efficient.

[0037] The working principle of this device will now be explained through its usage: First, a brief introduction to the background of its use is necessary. The preparation process of the adsorbent used in the detoxification of fly ash from waste incineration is generally as follows: attapulgite is first calcined, then activated with acetic acid, then dried, and finally ground. Drying and grinding are usually two separate steps, which greatly reduces the preparation efficiency of the adsorbent.

[0038] It should be noted that the adsorbent produced through the above process has the following functions:

[0039] 1. Strong adsorption capacity, used to adsorb dioxins and heavy metals in fly ash produced by waste incineration;

[0040] 2. The complex mesoporous and macroporous structure in the adsorbent can be used to immobilize soluble chlorine;

[0041] 3. The magnesium aluminum silicate structure in the adsorbent can be used for the exchange of magnesium ions with heavy metal ions, fixing the heavy metals into aluminosilicate stable substances.

[0042] It is precisely because the above-mentioned adsorbents have these functions that they are able to detoxify the fly ash produced by waste incineration.

[0043] This device is used to dry and grind the attapulgite filter cake formed after calcination and acetic acid activation of attapulgite in one step, thereby improving the preparation efficiency of the adsorbent.

[0044] When using this device, first place the attapulgite filter cake inside the inner box 34, then place the inner box 34 on the inner bottom surface of the receiving box 3, then cover it with the cover plate 23, and slide the top plate 2 into the top of the inner plate 21 through the sliding opening 13, thereby pressing the cover plate 23 against the top of the receiving box 3. Connect the external power socket through the plug 42 to power the electric heating grid 4, so that it can heat and dry the attapulgite filter cake inside the inner box 34 through heat conduction to the receiving box 3. At the same time, start the motor 5. The rotation of the output end of the motor 5 will drive the rotating shaft 51 and the convex ring sleeve 52 to rotate. The existence of the outer diameter gradient of 2, combined with the gravity of the through inclined block 32, the container 3 and the inner box 34 and the elastic force of the spring 22 on the container 3, causes the through inclined block 32, the container 3 and the inner box 34 to be lifted intermittently. This causes the attapulgite filter cake to move up and down in the inner box 34 and break after hitting the cone block 31. This accelerates the drying of the attapulgite filter cake while avoiding overheating that could cause structural changes that would affect its adsorption performance. After repeated impacts with the cone block 31, the attapulgite filter cake is broken to the target particle size, thus completing the drying and grinding of the attapulgite filter cake at the same time, which greatly improves the preparation efficiency of the adsorbent.

[0045] It should be noted that the through inclined block 32 is inclined upward relative to the housing 3 and is connected to the external environment. This not only enables the discharge of water vapor during the drying process of the attapulgite filter cake, but also prevents the broken attapulgite filter cake from flowing out along the gap inside the through inclined block 32 while vibrating up and down in the inner housing 34. This ensures the normal operation of the device and avoids waste.

[0046] Once the adsorbent is prepared, the inner box 34 can be removed to collect the adsorbent.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
