The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a pipeline trash rack, which is arranged in a pipeline system for conveying media and used for realizing external observation and internal detection, so that a device can be cleaned or replaced timely. The utility model discloses a structure includes pipeline body 1, blocks dirty 2 and detection piece 3. The pipeline body 1 comprises a straight pipe 101 which is arranged between a front pipeline and a rear pipeline to form a medium conveying channel, and is constructed below the straight pipe 101, a sewage discharge pipe 102 with one end communicated with the straight pipe 101 is arranged, the free end of the sewage discharge pipe 102 is an opening, the sewage blocking part 2 comprises an end cover 201 which is used for sealing the free end of the sewage discharge pipe 102, a filtering component 202 which is fixedly arranged on the end cover 201 and used for blocking impurities in media, and sampling bins 203 which are constructed on two sides of the filtering component 202 and located in the sewage discharge pipe, and the sampling bins 203 are used for collecting media on two sides of the filtering component 202. The detecting member 3 is disposed on the medium inflow side of the filter assembly 202 for determining the content of the impurities on the inflow side of the filter assembly 202.

Based on the above overall description, as shown in fig. 1, the pipe body 1 is divided into a straight pipe 101 for conveying a medium and a sewage pipe 102 having one end communicated with the straight pipe 101, and after the medium flows into the straight pipe 101, a part of the medium flows out from the straight pipe 101, and the other part of the medium flows into the sewage pipe 102. In order to better realize the using effect of the pipeline body, the sewage discharge pipe 102 is obliquely communicated with the straight pipe 101, and the free end of the sewage discharge pipe 102 is close to the medium outflow end of the straight pipe 101. In this embodiment, the appearance of pipeline body is "y" form, adopts other shapes of y type, like the t type, more advanced in the aspect of the structure, the resistance of medium circulation is little, and whole equipment washes the convenience, also is convenient for clear up debris simultaneously and installs the dismantlement.

The other end of the sewage draining pipe 102 is provided with a trash rack 2. The trash rack 2 includes an end cap 201, a filter assembly 202, and a sampling bin 203. The end cap 201 closes the waste pipe 102 so that the medium flowing to the waste pipe 102 is stored in the waste pipe 102. In addition, the filtering component 202 of the trash rack 2 can intercept impurities in the medium passing through the straight pipe 101, and damage to the pipeline system caused by the medium flowing out of the straight pipe 101 is reduced. Furthermore, the sampling bins 203 are arranged at both sides of the filtering component 202, and the media at both sides of the filtering component 202 can be collected by the sampling bins 203, and then the trash rack 2 is taken out of the sewage discharge pipe 102. The media in the sampling bin 203 can be detected, the impurity contents on the two sides of the filter assembly 202 are compared, the working efficiency and the loss degree of the filter assembly 202 are judged by combining the filtered impurity contents, and a corresponding processing mode is made, such as cleaning or replacement.

The end cover 201 of the trash rack 2 is used for closing the free end of the sewage pipe 102, so that the connection mode of the end cover and the sewage pipe 102 is diversified, and in the embodiment, the sewage pipe 102 is connected with the end cover 201 through bolts. The free end of the sewage draining pipe 102 is provided with a flange, and corresponding to the flange, the end cover 201 is provided with a corresponding mounting hole, so that the sewage draining pipe 102 and the end cover 201 can be conveniently connected by adopting bolts. And some devices such as gaskets may be added between the flange and the end cap 201 to increase the pipe tightness. Of course, the connection can be made in other manners, such as inserting the end cap 201 into the sewage pipe 102 by a rotary insertion manner, or by a clamping manner, but the connection is made by bolts, which is not only convenient and easy to operate, but also does not affect the installation position of the filter assembly 202 during installation, and is also very convenient and material-saving in production and manufacture.

The filter assembly 202 extends outwardly from the end cap 201 and eventually abuts the inner wall of the straight pipe 101 to trap contaminants throughout the media passing through the straight pipe 101. The filter assembly 202 can be one or more filter screens, or can be a support seat and a filter screen, and the like, the installation and composition technology of the filter assembly 202 is mature at present, the requirement that the comprehensive shielding medium flows through the pipeline body 1 can be met, and the specific style is not limited.

Meanwhile, sampling bins 203 are arranged on two sides of the filter assembly 202, and the sampling bins 203 can be arranged on the filter assembly 202 and also can be arranged on the end cover 201. The sampling bin 203 can collect media passing through the filter assembly 202 and media not passing through the filter assembly 202, so that the media can be detected after the trash piece 203 is taken out, the loss degree of the filter assembly is judged, and then a decision on cleaning or replacement is made.

In this embodiment, the sampling chamber 203 is configured on the end cap 201 and is tightly attached to the inner wall of the drainage pipe 102. The sampling device is constructed on the end cover 201, so that the medium can flow into the sampling bin 203, and the final use purpose cannot be influenced by the length of the sewage discharge pipe 102. Meanwhile, the sampling bin 203 is tightly attached to the inner wall of the sewage discharge pipe 102, and when the sewage blocking piece 2 is installed, the sealing performance of the connection between the end cover 201 and the sewage discharge pipe 102 is improved.

Based on the structural description of the upper sampling bin 203, in order to further improve the sampling accuracy and ensure the accuracy of the processing result, the medium inflow end of the sampling bin 203 is extended to the joint of the sewage pipe 102 and the straight pipe 101. When the design is used for medium internal detection, the sampling is required to be carried out on one side of the medium inflow end close to the sampling bin 203, so that the error caused by excessive impurities at the bottom of the sampling bin can be avoided, and more accurate processing suggestions can be made.

Of course, if the trash rack 2 needs to be repeatedly disassembled according to the above-described determination method, which may increase the amount of maintenance and inspection work, the detection member 3 is provided on the medium inflow side of the filter assembly 202 for more convenient and rapid determination. The filter assembly 202 will intercept contaminants in the media, and the intercepted contaminants will dissolve in the media flowing to the filter assembly 202, which will cause a partial change in the properties of the media flowing to the filter assembly 202, such as concentration, pressure, or clarity. The detecting member 3 is designed to detect the change of the medium flowing to the filter assembly 202, so as to determine the content of impurities on the medium inflow side of the filter assembly 202, and further perform the above-mentioned disassembling operation and internal detection, and finally determine the processing decision of the device.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
