Description

Technical Field

[0001] The utility model relates to the technical field of sludge pipeline transportation, in particular to a sludge pipeline direct-connected impurity remover. Background Art

[0002] In recent years, due to environmental protection needs, a large amount of sludge needs to be reduced, stabilized, and harmlessly treated, and pipeline transportation is usually used in the process. Municipal sludge and industrial sludge are solid sediments produced after water or sewage passes through the purification process. They are in a paste state and contain a large amount of organic matter, microorganisms, heavy metals, etc., which are very harmful and must be treated. Since the sludge contains large particles, it will affect the subsequent treatment equipment, and in severe cases it will even cause the entire system to shut down. Therefore, it is necessary to reduce, stabilize, and harmlessly treat the sludge. The pipeline impurity removal device is a pipeline connection accessory that can remove particles of a certain specification. It is composed of a pipe sleeve and a wire filter. When the sludge passes through the device, large particles of impurities are left in the wire filter. It is suitable for working conditions with low sludge pressure and small flow. It is not easy to maintain and has a short service life.

[0003] The existing sludge pipeline impurity remover in my country is an L-shaped pipeline impurity remover. The inlet and outlet of the impurity remover are arranged at a right angle of 90 degrees. The pressure of the sludge is greatly attenuated when passing through the impurity remover, resulting in a significant reduction in the conveying distance. The conveying pressure of the paste pump must be increased to solve this problem, which undoubtedly increases the energy consumption of the equipment and the installation form is relatively simple. Utility Model Content

[0004] The utility model aims to solve the limitation of the installation form of the impurity remover in the prior art and the problem of impurity removal in the paste material conveying pipeline, and proposes a sludge pipeline direct-connected impurity remover.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sludge pipe direct-connected impurity remover comprises an impurity remover shell, and also comprises: an impurity remover feed port, fixedly connected to the left side of the impurity remover shell, and an impurity remover discharge port, fixedly connected to the right side of the impurity remover shell; a squirrel cage, arranged in the impurity remover shell, and an inspection end cover is arranged on the top of the squirrel cage; and a pressure sensor, fixedly connected to the inner wall of the impurity remover shell.

[0007] Preferably, the impurity remover shell is made of manganese steel with a wall thickness of not less than 20 mm. The impurity remover shell adopts a Y-shaped structure with a minimum pressure resistance of 20 MPa.

[0008] Preferably, the squirrel cage is made of stainless steel bars of no less than ten millimeters, the squirrel cage is fixedly connected to the inner wall of the impurity remover housing, and the squirrel cage is fixedly connected to the inspection end cover by bolts.

[0009] Preferably, two groups of pressure sensors are provided and are symmetrically arranged with the center line of the impurity remover housing as the symmetry axis.

[0010] Preferably, the pressure sensor is fixedly connected to the inlet and outlet of the impurity remover housing, and the value of the pressure sensor can be displayed in real time on the host computer, with a high pressure warning prompt.

[0011] Compared with the prior art, the utility model provides a sludge pipeline direct-connected impurity remover, which has the following beneficial effects:

[0012] 1. The sludge pipeline direct-connected impurity remover adopts control systems such as human-machine interface and PLC programmable control to realize pressure display and blockage warning of the impurity remover and timely cleaning and maintenance. The squirrel cage is arranged and installed in a Y-shaped structure, and the arrangement form is a docking form, which effectively reduces the pressure loss in the pipeline. The installation form is installed parallel to the pipeline, breaking the installation form limitations of the existing impurity remover and completely making up for the problem of impurity removal in the paste material conveying pipeline.

[0013] 2. The sludge pipe direct-connected impurity remover adopts the form of pipe docking to effectively solve the pressure loss and energy waste problems in the 90-degree right-angle arrangement in the prior art. By adopting the impurity remover shell made of manganese steel and the squirrel cage made of stainless steel, the equipment can withstand a larger pressure range and have a longer service life.

[0018] Reference Figure 1 A sludge pipeline direct-connected impurity remover comprises an impurity remover shell 1, and also comprises: an impurity remover feed port 2, which is fixedly connected to the left side of the impurity remover shell 1, and an impurity remover discharge port 3 is fixedly connected to the right side of the impurity remover shell 1; a squirrel cage 4, which is arranged in the impurity remover shell 1, and an inspection end cover 5 is arranged on the top of the squirrel cage 4; a pressure sensor 6, which is fixedly connected to the inner wall of the impurity remover shell 1. When in use, paste material or sludge enters the impurity remover shell 1 through the impurity remover feed port 2, and the paste material or sludge passes through the squirrel cage 4 to isolate impurities, and then the clean material finally enters the next process through the impurity remover discharge port 3. By adopting the pipeline docking form, the pressure loss in the pipeline is effectively reduced, and the installation form is installed in parallel with the pipeline, which breaks the installation form limitation of the existing impurity remover and completely makes up for the impurity removal problem of the paste material conveying pipeline.

[0019] The impurity remover housing 1 is made of manganese steel with a wall thickness of not less than 20 mm. The impurity remover housing 1 adopts a Y-shaped structure with a minimum pressure resistance of 20 MPa.

[0020] The squirrel cage 4 is made of stainless steel bars of no less than ten millimeters. The squirrel cage 4 is fixedly connected to the inner wall of the impurity remover housing 1. The squirrel cage 4 and the maintenance end cover 5 are fixedly connected with bolts. By using stainless steel material, the equipment can withstand a larger pressure range during use and have a longer service life. The squirrel cage 4 and the maintenance end cover 5 are connected with bolts, which can be easily disassembled for maintenance and cleaning.

[0021] There are two groups of pressure sensors 6 and both are symmetrically arranged with the center line of the impurity remover housing 1 as the symmetry axis.

[0022] The pressure sensor 6 is fixedly connected to the inlet and outlet of the impurity remover housing 1. The value of the pressure sensor 6 can be displayed in real time on the host computer, and there is a high-pressure early warning prompt. When the pressure difference of the pressure sensor 6 is greater than the set range, the system will automatically alarm, indicating that the cage 4 has been filled with debris. The inspection end cover 5 can be disassembled to remove the debris from the cage 4.

[0023] In the utility model, when in use, the paste material or sludge enters the impurity remover shell 1 through the impurity remover feed port 2, the paste material or sludge passes through the cage 4, the impurities are isolated, and then the clean material finally enters the next process through the impurity remover discharge port 3. When the cage 4 is filled with impurities, the pressure difference of the pressure sensor 6 at this time is greater than the set range, and it will automatically alarm, prompting the staff to disassemble the inspection end cover 5 and clean the impurities in the cage 4. The Y-shaped structural arrangement effectively reduces the pressure loss in the pipeline, and the installation form is installed in parallel with the pipeline, breaking the installation form limitation of the existing impurity remover and completely making up for the problem of impurity removal in the paste material conveying pipeline.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
