Description

Technical Field

[0001] The utility model belongs to the field of dust removal equipment, and more specifically relates to an environmentally friendly faulty dust removal quick processing valve. Background Art

[0002] The dust removal system of the bag filter is composed of a star valve, a gate valve, and a dust removal suction pipe. During normal production, the dust collected in the bag filter needs to be discharged in time through the dust removal system to ensure the stable operation of the dust removal system. Due to the occasional entry of debris into the air intake or the failure of the dust removal valve, the star-shaped dust removal valve is blocked and the gate valve is not closed tightly. Dozens of tons of accumulated dust in the ash tank cannot be discharged normally. The premise for handling the star valve and the gate valve is that the accumulated dust in the tank must be discharged from the ash bin first. The process will cause environmental pollution, and manual cleaning is time-consuming and labor-intensive. If the processing time is too long, the environmental dust removal system will not operate normally, affecting production and environmental protection.

[0003] The shortcomings of the current bag dust collector dust unloading facilities are as follows:

[0004] 1. The ash discharge valve fails and becomes clogged, making it impossible to ensure that maintenance and production can be carried out simultaneously;

[0005] 2. When ash blockage occurs, the ash in the ash bin must be discharged to the ground before maintenance can be carried out, causing serious pollution on site;

[0006] 3. Cleaning up the scattered dust on the ground is time-consuming and laborious;

[0007] 4. When the smelting process changes, resulting in changes in the composition of the dust ash, such as when the density of the dust ash increases, the insufficient suction power of the original ash conveying and suction vehicle will cause blockage. Utility Model Content

[0008] The purpose of the utility model is to provide an environmentally friendly fault-discharging quick processing valve to address the deficiencies in the prior art. When a star valve and a plug valve are blocked by ash, the processing valve can use a bypass structure to discharge ash, thereby shutting down the star valve and the plug valve for cleaning, thereby ensuring normal ash discharge from the ash tank and realizing the cleaning operation of the valve body.

[0009] In order to achieve the above-mentioned purpose, the utility model provides an environmentally friendly fault ash removal rapid treatment valve, comprising:

[0010] A gate valve, one end of which is connected to the ash tank via a first pipeline, and the other end of which is connected to one end of the star valve via a second pipeline;

[0011] An ash conveying pipeline, one end of which is connected to the other end of the star valve through the third pipeline;

[0012] A bypass structure has one end connected to the first pipeline and the other end connected to the third pipeline.

[0013] Optionally, the bypass structure includes a bypass pipeline and a bypass ball valve, the bypass ball valve is connected in series to the bypass pipeline, and both ends of the bypass pipeline are respectively connected to the first pipeline and the third pipeline.

[0014] Optionally, the gate valve is detachably connected to the first pipeline and the second pipeline.

[0015] Optionally, the star valve is detachably connected to the second pipeline and the third pipeline.

[0016] Optionally, a nitrogen blowing-assisting pipe is provided in the ash conveying pipeline, and a blowing-assisting ball valve is provided on the nitrogen blowing-assisting pipe.

[0017] Optionally, a plurality of nitrogen blowing tubes are provided.

[0018] Optionally, a star valve motor is provided on the star valve.

[0019] The utility model provides an environmentally friendly fault ash removal quick treatment valve, which has the following beneficial effects:

[0020] 1. The treatment valve is easy to operate and highly practical. A bypass pipeline is set up. When the plug valve and star valve are blocked by ash, the bypass pipeline can be used to replace them to achieve normal ash discharge. This can not only ensure that the discharge meets environmental standards, but also solve the problem of production interruption during ash cleaning;

[0021] 2. The treatment valve is equipped with multiple nitrogen blowing pipes in the ash conveying pipeline. By pressurizing the ash conveying pipeline, a higher boosting density is achieved, which can remove sticky dust and solve the problem of obstructed ash discharge.

[0022] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] The utility model provides an environmentally friendly fault ash removal quick processing valve, comprising:

[0029] A gate valve, one end of which is connected to the ash tank through a first pipeline, and the other end of which is connected to one end of the star valve through a second pipeline;

[0030] An ash conveying pipeline, one end of which is connected to the other end of the third pipeline star valve;

[0031] The bypass structure has one end connected to the first pipeline and the other end connected to the third pipeline.

[0032] Specifically, in the processing valve, a gate valve and a star valve are sequentially arranged on the main ash discharge path, so that the ash tank is connected to the ash conveying pipeline. In addition, a bypass structure is connected to the first pipeline and the third pipeline. The bypass structure is connected in parallel with the gate valve and the star valve. When the gate valve and the star valve are blocked, the dust in the ash tank can be discharged into the ash conveying pipeline through the bypass structure, which can ensure normal ash discharge. In addition, the gate valve and the star valve can be cleaned and maintained under normal ash discharge conditions, thereby improving work efficiency.

[0033] In one embodiment, control valves are respectively provided on the first pipeline and the third pipeline, so that when the bypass structure is discharging dust, the control valves on the two pipelines can be closed, so that dust will not pass through the gate valve and the star valve, and the gate valve and the star valve can be cleaned.

[0034] Optionally, the bypass structure includes a bypass pipeline and a bypass ball valve, the bypass pipeline is connected in series with the bypass ball valve, and both ends of the bypass pipeline are respectively connected to the first pipeline and the third pipeline.

[0035] Specifically, the bypass structure includes a bypass pipeline and a bypass ball valve. When the ash discharge volume of the ash conveying pipeline is reduced, the gate valve and the star valve can be closed and the bypass ball valve can be opened at the same time. In this way, the dust in the ash tank can be discharged normally through the ash conveying pipeline. The gate valve and the star valve can be inspected, and when ash blockage occurs, they can be cleaned and maintained in time.

[0036] Optionally, the gate valve is detachably connected to the first pipeline and the second pipeline.

[0037] Optionally, the star valve is detachably connected to the second pipeline and the third pipeline.

[0038] Specifically, the gate valve and the star valve are both detachably connected, so when cleaning the valve body, the gate valve and the star valve can be removed and transferred to a workbench for cleaning operations to avoid scattering dust on the ground and causing secondary pollution.

[0039] Optionally, a nitrogen blowing-assisting pipe is provided in the ash conveying pipeline, and a blowing-assisting ball valve is provided on the nitrogen blowing-assisting pipe.

[0040] Optionally, a plurality of nitrogen blowing tubes are provided.

[0041] Specifically, multiple nitrogen blowing pipes are added to the ash conveying pipeline and ball valve control is set. During the ash unloading process, if the dust ash composition changes due to changes in the production process, resulting in blockage in the ash discharge process, the blowing valve can be gradually opened and adjusted to achieve smooth transportation of the dust ash.

[0042] Optionally, a star valve motor is provided on the star valve.

[0043] Specifically, the star valve is controlled by a star valve motor to reduce the operator's labor intensity, and the processing valve can be remotely operated. When the ash conveying pipeline tends to be blocked, the star valve is started to clean the pipeline. The star valve motor can also be set to start regularly, so that the ash conveying pipeline can be regularly cleaned to keep the ash conveying pipeline unobstructed.

[0044] In one embodiment, in addition to the star valve which can be opened and closed by motor control, other valve bodies in the treatment valve can also be controlled by electric control, so that automatic dust removal operation can be performed according to the set dust cleaning program.
