Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic unloading of storage boxes with single bins and multiple bins, and specifically relates to a pneumatic conveying and dropping recovery pipeline for granular activated carbon. Background Art

[0002] Activated carbon adsorption box is a common treatment facility in the VOCs waste gas treatment industry. The activated carbon adsorption box is filled with granular activated carbon adsorbent. The adsorbent needs to be replaced regularly. The replaced waste activated carbon is a hazardous waste and is toxic. When the adsorbent is replaced in the "bottom-discharge" activated carbon adsorption box, the granular activated carbon is discharged from the discharge port at the bottom of the carbon layer.

[0003] The existing activated carbon adsorption boxes are installed on high floors. When the granular activated carbon is unloaded by traditional manual unloading and transportation methods, it is time-consuming and labor-intensive, the unloading cost is high, and the waste activated carbon dust is flying during unloading, which is toxic to the workers' health and the workers' working environment is poor;

[0004] When the granular activated carbon is unloaded by pipeline transportation, the granular activated carbon falls from the discharge port at the bottom of the activated carbon adsorption box to the horizontal discharge pipe, and then falls by gravity from the vertical discharge pipe.

[0005] However, there is a certain distance between the existing activated carbon adsorption box and the vertical discharge pipe, and the lifting height of the base of the activated carbon adsorption box is limited, and the inclination angle of the horizontal discharge pipe is small, making discharge difficult.

[0027] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0028] Specifically, Figures 1 to 7 As shown, a pneumatic conveying and recycling pipeline for granular activated carbon includes a discharge assembly 1 and a blowing assembly 2 connected to the discharge assembly 1;

[0029] The discharge assembly 1 includes a main discharge pipe 11, a first discharge port 12 and a second discharge port 13 installed on the main discharge pipe 11, a raised portion 14 provided at the front section of the main discharge pipe 11, and a connecting flange 15 installed at one side of the raised portion 14;

[0030] The blowing-assisting assembly 2 includes a main air intake pipe 21, a three-way joint 22 connected to the main air intake pipe 21, a first blowing-assisting pipe 23 and a hose 24 respectively connected to the other two ends of the three-way joint 22, a second blowing-assisting pipe 26 connected via an elbow joint 25, and a first control ball valve 27 and a second control ball valve 28 respectively arranged at the connection between the first blowing-assisting pipe 23 and the hose 24 and the three-way joint 22.

[0031] It should be noted that the granular activated carbon in the activated carbon adsorption box is transported through the discharging component 1, and for the activated carbon adsorption box with two or more bins, an independent blowing component 2 is used for each bin, so that the activated carbon in each bin can be quickly transported;

[0032] In detail, when the first bin is unloading, the main air inlet pipe 21 supplies air, and the rotary locking mechanism 3 at the second bin position lifts the second blowing-assisting pipe 26 to ensure that the main discharge pipe 11 is unobstructed, and to prevent the second blowing-assisting pipe 26 from blocking the main discharge pipe 11 and affecting the breakage rate of the granular activated carbon unloaded from the first bin; then the first control ball valve is opened to allow the first blowing-assisting pipe 23 to feed by means of negative pressure, thereby completing the unloading of the first bin. When the second bin is unloading, the main air inlet pipe 11 also maintains air supply, and the rotary locking mechanism 3 at the second bin position drops the second blowing-assisting pipe 26, and then the second control ball valve 28 is opened to allow the second blowing-assisting pipe 26 to feed by means of negative pressure, thereby completing the unloading of the second bin.

[0033] The rotary locking mechanism 3 includes a rotating plate 31 fixedly connected to the second blowing-assisting pipe 26, a fixing plate 32 fixedly mounted on the protruding portion 14, a fixing pin 33 penetrating the rotating plate 31, and a limiting ring 34 disposed at the front end of the fixing pin 33;

[0034] A spring 35 is sleeved on the surface of the fixing pin 33 between the rotating plate 31 and the limiting ring 34 , and an adjustment hole 36 matching the fixing pin 33 is opened on the fixing plate 32 .

[0035] It should be noted that the second blowing-assisting pipe 26 can be adjusted up and down by rotating the locking mechanism 3, that is, the pipe mouth is lowered during operation and raised during non-operation without blocking the material;

[0036] In detail, when the second blowing-assisting pipe 2 needs to be lifted upward, the fixing pin 33 is first pulled out from the adjusting hole 36 on the fixing plate 32, and then the second blowing-assisting pipe 26 is driven to rotate through the rotating plate 31, so that the second blowing-assisting pipe 26 is rotated into the raised portion 14. After the rotation is completed, the fixing pin 33 is inserted into the corresponding adjusting hole 36 on the fixing plate 32, and the limiting ring 34 is squeezed and abutted against the fixing plate 32 through the external elastic force of the spring 35, thereby completing the fixation.

[0037] The first blowing-assisting pipe 23 penetrates the main discharge pipe 11 and extends to below the first material drop opening 12 , and the second blowing-assisting pipe 26 penetrates the main discharge pipe 11 and extends to below the second material drop opening 13 .

[0038] The distance between the top of the first blowing-assisting pipe 23 and the first conical blanking opening 12 is set to 10 mm, and the extending length of the first blowing-assisting pipe 23 exceeds the conical edge of the blanking opening by 100-130 mm.

[0039] It should be noted that the air outlets of the first blowing-assisting pipe 23 and the second blowing-assisting pipe 26 are both located in front of the first material drop opening 12 and the second material drop opening 13, and the granular activated carbon entering through the material drop opening is transmitted by generating negative pressure through blowing.

[0040] The main discharge pipe 11 is made of 4-inch stainless steel pipe material, and the first discharge port 12 and the second discharge port 13 both adopt conical design flanges.

[0041] It should be noted that the outlet diameter at the lower end of the drop port is more than 1 inch smaller than the horizontal discharge pipe. A guide inclined plate is optionally installed inside the drop port to control the air flow speed, ensure the formation of sufficiently large negative pressure and air flow speed, and guide the material to drop into the discharge pipe.

[0042] The specific working method is described below with specific embodiments: Example 1

[0043] When the first bin is unloading, the main air intake pipe 21 supplies air, and the rotary locking mechanism 3 at the second bin position lifts the second blowing pipe 26 to ensure that the main discharge pipe 11 is unobstructed, and the second blowing pipe 26 is prevented from blocking the main discharge pipe 11 and affecting the breakage rate of the granular activated carbon unloaded from the first bin; then the first control ball valve is opened to allow the first blowing pipe 23 to feed by means of negative pressure, thereby completing the unloading of the first bin. When the second bin is unloading, the main air intake pipe 11 also maintains air supply, and the rotary locking mechanism 3 at the second bin position drops the second blowing pipe 26, and then the second control ball valve 28 is opened to allow the second blowing pipe 26 to feed by means of negative pressure, thereby completing the unloading of the second bin. More bins are operated in the same manner, with the air source blowing pipe of the working bin being rotated and dropped, and the air source blowing pipe of the non-working bin being rotated and lifted for operation. Example 2

[0044] When it is necessary to lift the second blowing-assisting pipe 2 upward, first pull out the fixing pin 33 from the adjusting hole 36 on the fixing plate 32, and then drive the second blowing-assisting pipe 26 to rotate through the rotating plate 31, so that the second blowing-assisting pipe 26 rotates into the raised portion 14. After the rotation is completed, the fixing pin 33 is inserted into the corresponding adjusting hole 36 on the fixing plate 32, and the limiting ring 34 is squeezed and abutted against the fixing plate 32 through the external elastic force of the spring 35, thereby completing the fixation, that is, the pipe mouth is dropped during operation, and the lifting type does not block the material when not in operation.

[0045] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above-mentioned concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
