Description

Technical Field

[0001] The present invention relates to the technical field of conveyor cleaning equipment, in particular to a device for cleaning an adhesive layer attached to a conveyor belt of a conveyor. The present invention also relates to a method for cleaning an adhesive layer attached to a conveyor belt of a conveyor. Background Art

[0002] Conveyor belts are widely used in metallurgy, mining, building materials, chemicals, and food, and are mostly used to transport powdered materials. After the conveyor belt has been working for a period of time, sticky materials often appear on the surface of the return conveyor belt. These sticky materials scatter irregularly along the way, polluting the environment, and long-term accumulation will interfere with the normal operation of the conveyor belt.

[0003] Existing conveyor belt sticky material removal technologies include mechanical scraping, roller brush cleaning and other methods. These methods work well in the initial operation of a new conveyor belt, but as time goes by, the effect becomes increasingly worse until the cleaning effect is lost.

[0004] Taking mechanical scraping as an example, the blade of the sweeper must be in close contact with the conveyor belt to achieve the cleaning effect, but it also increases the friction between the blade of the sweeper and the conveyor belt, causing wear on the blade and the conveyor belt. Some sweepers are not installed in the correct position. A large blade is used on a small rack on site, but the position is not adjusted, resulting in the blade sweeping backward. The small rack has a large blade, but the tensioner is still small, resulting in the blade not being able to stick to the conveyor belt, so the ideal effect cannot be achieved, and the wear is large, requiring irregular replacement, which is time-consuming and labor-intensive, with a short service life and a high maintenance frequency. Summary of the invention

Moreover, compared with ordinary high-pressure gas, the high-pressure mist contains 1-10um water particles, so it can achieve a better cleaning effect.

[0036] The high-pressure atomization cleaning method for conveyor belts provided by the present invention can ensure that the moisture fluctuation of the material is within the allowable process range by controlling the amount of water vapor atomization, and will not affect the production parameters of the process flow. In addition, by controlling the atomized moisture, a large amount of dripping water on the conveyor belt can also be avoided to cause secondary pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] In this article, the terms "up, down, left, right" and the like are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. In the part of the specification that has a definition of direction, the directions defined by the text are given priority. Therefore, they cannot be understood as an absolute limitation on the scope of protection; moreover, relational terms such as "first" and "second" are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0044] Research has found that the difficulty in cleaning the conveyor belt is closely related to the adhesive layer formed on its surface after the conveyor belt has been working for a long time. Traditional cleaning methods can only remove floating materials that are not firmly bonded to the surface of the conveyor belt, but cannot remove the adhesive layer of the conveyor belt.

[0045] The adhesive layer on the surface of the conveyor belt is formed by mixing ultrafine powder with water. This adhesive layer is initially in the form of mud and is very thin, usually between 1mm and 3mm. As time goes by, the water in this adhesive layer evaporates, the adhesive layer becomes harder and thicker, and the bonding strength between it and the conveyor belt increases, making it increasingly difficult to remove.

[0046] Since the adhesive layer is composed of powder of the raw material, it has a strong affinity with the raw material. Once it is fully covered, the conveyor belt will become sticky and the difficulty of removing the sticky material will increase sharply, or even become impossible to remove. To completely solve the problem of conveyor belt sticking, it is necessary to prevent the formation of the adhesive layer. This is also the fundamental reason why the conveyor belt has a serious sticking phenomenon after running for a period of time, and the conveyor belt cleaning machine has poor cleaning effect or even cannot remove it.

[0047] like Figure 1 , Figure 2 As shown, in a specific embodiment, the conveyor belt high-pressure atomization cleaning device provided by the present invention is mainly composed of a booster pump 1, a valve pipeline assembly 2, a high-pressure atomizer 3, an air knife 4 and pipelines connecting the above components.

[0048] The booster pump 1 is used to boost the compressed air output by the air source to a pressure greater than or equal to 0.8 MPa. The valve pipeline assembly 2 is used to regulate and control the compressed air after the pressure is increased by the booster pump 1. The booster pump 1 is connected to the compressed air inlet of the high-pressure atomizer 3 through the valve pipeline assembly 2.

[0049] The air knife 4 is an open slit air knife with an opening width of 0.2mm to 0.5mm, and a spacing between its opening and the conveyor belt 5 of 5mm-10mm, so as to ensure the blowing pressure of the air knife 4 on the conveyor belt 5. When in use, the air knife 4 is arranged below the conveyor belt 5 along the width direction of the conveyor belt 5, with its opening facing upward, toward the lower surface of the conveyor belt 5 after unloading, so as to clean the conveyor belt 5. The high-pressure mist outlet 32 ​​of the high-pressure atomizer 3 is connected to the air inlet end of the three-way valve 6, and the first air outlet end and the second air outlet end of the three-way valve 6 are respectively connected to the first air inlet and the second air inlet located on both sides of the air knife 4.

[0050] The valve pipeline assembly 2 is mainly composed of a check valve 21, a connecting valve 22, a pressure reducing valve 23 and a ball valve 24. The air inlet end of the check valve 21 is connected to the air outlet end of the boost pump 1, the air inlet end of the connecting valve 22 is connected to the air outlet end of the check valve 21, the air inlet end of the pressure reducing valve 23 is connected to the air outlet end of the connecting valve 22, the air inlet end of the ball valve 24 is connected to the air outlet end of the pressure reducing valve 23, and the air outlet end of the ball valve 24 is connected to the compressed air inlet of the high-pressure atomizer 3.

[0051] In this embodiment, the connecting valve 22 is a four-way valve having four ports that can be connected to each other, the first port is the air inlet end, the second port is the air outlet end, the third port is connected to the buffer tank 7, and the fourth port is connected to the pressure gauge 8.

[0052] Of course, if the pressure gauge 8 is not provided or is installed at other locations, for example, when the pressure gauge 8 is installed on a pipeline, the connecting valve 22 may also be a three-way valve having three ports that can be interconnected, the first port being the air inlet end, the second port being the air outlet end, and the third port being connected to the buffer tank 7.

[0053] The high-pressure atomizer 3 is provided with a compressed air inlet 31 and a high-pressure mist outlet 32, and is provided with a water storage chamber 33 for storing water and an atomization structure arranged in the water storage chamber, and the atomization structure is used to convert the input compressed air into high-pressure mist.

[0054] Specifically, the atomization structure includes a water suction pipe 34, an intermediate pipe 35 and an atomization plate 36. The water suction pipe 34 is arranged vertically and is in the shape of a cone with a diameter at the upper end smaller than that at the lower end. The lower end is located below the liquid surface of the water, and the upper end extends upward to a position opposite to the atomization plate 36; the intermediate pipe 35 is located inside the water suction pipe 34, the lower end of which is connected to the compressed air inlet 31, and the upper end is retracted inward by a certain distance relative to the water suction pipe 34, so that an annular space is formed between the water suction pipe 34 and the intermediate pipe 35, so as to utilize the negative pressure generated by the high-speed airflow to drive the water to be sprayed to the atomization plate 36.

[0055] The bottom surface of the atomizing plate 36 opposite to the upper end of the water suction pipe 34 is a plane, the top of the atomizing plate 36 is in the shape of a cone with a small top and a large bottom, a top cover 37 is provided above the water containing chamber 33, the inner cavity of the top cover 37 is in the shape of a cone with a small top and a large bottom, the high-pressure mist outlet 32 ​​is located at the top of the cone in the middle of the top cover 37, and the outer surface of the top of the atomizing plate 36 and the inner surface of the top cover 37 form a flow space for guiding the high-pressure mist to converge to the high-pressure mist outlet 32.

[0056] The water suction pipe 34 is configured to be able to move up and down relative to the intermediate pipe 35 to adjust the annular gap between the upper end of the intermediate pipe 35 and the water suction pipe 34; or, the intermediate pipe 35 is configured to be able to move up and down relative to the water suction pipe 34 to adjust the annular gap between the upper end of the intermediate pipe 35 and the water suction pipe 34. For example, a driving device such as a motor or a cylinder can be connected to the water suction pipe 34 or the intermediate pipe 35 through a transmission mechanism, thereby driving the water suction pipe 34 or the intermediate pipe 35 to move up and down. Since it can be achieved by using general technology, it will not be described in detail herein.

[0057] By setting the gap between the middle pipe 35 of the high-pressure atomizer 3 and the water suction pipe 34 to be adjustable, the water absorption amount of the water suction pipe 34 can be adjusted, thereby adjusting the atomization amount.

[0058] A water level gauge 38 is provided on the high-pressure atomizer 3. When the water level is lower than the water level warning value, the water valve 39 is opened and water is added from the water inlet 310 to ensure the real-time operation of the high-pressure atomizer 3. Moreover, the atomization amount of the high-pressure atomizer 3 can be measured in real time through the water level gauge 38.

[0059] When the equipment is running, the 0.4-0.6MPa compressed air from the factory is pressurized to about 0.8MPa by the booster pump 1 (for the consolidation layer of the conveyor belt, a pressure above 0.8MPa has a better cleaning effect), and enters the connecting valve 22 after passing through the check valve 21. The other side of the connecting valve 22 is the buffer tank 7. Through the function of the buffer tank 7, the compressed air pressure and flow rate can be stabilized. The pressure of the compressed air is controlled by the pressure reducing valve 23 to about 0.8MPa. After passing through the ball valve 24, it enters the high-pressure atomizer 3. In the high-pressure atomizer 3, the negative pressure generated by the high-speed airflow ejected from the middle pipe 35 drives the water (Chewley effect) to be ejected onto the atomizing plate 36 through the water suction pipe 34. Under high-speed impact, the splashing droplets become mist particles and are ejected from the high-pressure mist outlet 32. After that, the high-pressure mist enters the two sides of the narrow slit air knife 4 through the three-way valve 6, so that the pressure and flow of the air knife 4 are evenly distributed along the width of the conveyor belt.

[0060] The high-pressure mist sprayed from the air knife 4 can completely remove the conveyor belt consolidation layer 51. Since it does not contact the conveyor belt 5, it will not affect the operation and maintenance of the conveyor belt 5. Moreover, compared with ordinary high-pressure gas, the high-pressure mist contains 1-10um water particles, so it can achieve the effect of thoroughly cleaning the conveyor belt 5.

[0061] like Figure 3 As shown, in addition to the above-mentioned conveyor belt high-pressure atomization cleaning device, the present invention also provides a conveyor belt high-pressure atomization cleaning method, which uses the conveyor belt high-pressure atomization cleaning device described above to clean the conveyor belt, mainly comprising the following steps:

[0062] Collect the material volume M at the conveyor belt inlet;

[0063] Collect atomized water volume Q;

[0064] Determine whether the atomized water volume Q is greater than N1×M×α×β, where N1 is the set lower limit percentage, α is the standard moisture content of the material, and β is the allowable fluctuation rate of the moisture content of the material;

[0065] If the judgment result is no, the annular gap B between the upper end of the intermediate pipe and the water suction pipe is increased by ΔB1 each time, and the atomized water volume Q is further judged to be greater than N1×M×α×β;

[0066] If the judgment result is yes, then further judge whether the atomized water volume Q is less than N2×M×α×β, where N2 is the set upper limit percentage;

[0067] If the judgment result is no, the annular gap B between the upper end of the intermediate pipe and the water suction pipe is reduced by ΔB2 each time, and the atomized water volume Q is further judged to be less than N2×M×α×β;

[0068] If the judgment result is yes, the adjustment is ended.

[0069] In the above method, the value range of N1 is 78% to 82%, the value range of N2 is 88% to 92%, and ΔB1 is greater than ΔB2.

[0070] In this embodiment, the value of N1 is 80%, the value of N2 is 90%, the value of ΔB1 is 1 mm, and the value of ΔB2 is 2 mm.

[0071] By controlling the amount of water vapor atomization, it is possible to ensure that the moisture fluctuation of the material is within the allowable process range and will not affect the production parameters of the process. In addition, by controlling the amount of atomized water, it is also possible to avoid the formation of a large amount of dripping water on the conveyor belt, which can cause secondary pollution.

[0072] The above is a detailed introduction to the conveyor belt high-pressure atomization cleaning device and method provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
