Description

TECHNICAL FIELD

[0001] The application relates to a sludge sampling mechanism. BACKGROUND

[0002] Sludge ceramsite is a kind of light and porous granular material made of sludge as raw material through processes such as crushing, mixing, molding and calcination. It has many advantages and is an ideal choice for environmental protection building materials.

[0003] In the manufacturing process of sludge ceramsite, sludge needs to be transported from one process to the next. Due to the complex composition of sludge, it is necessary to determine the specific composition of sludge and provide a basis for the formulation of ceramsite ratio and process parameters. Therefore, a sampling mechanism is needed to sample the sludge during transportation. Through sampling analysis, production process parameters such as calcination temperature, time and additive ratio can be adjusted.

[0004] The conventional sampling method usually has a sampling port on the conveying pipe. The sampling port is opened and the sampling device is inserted into the conveying pipe to complete the sampling operation.

[0005] During sludge transportation, phenomena such as settling, stratification and mixing may occur, resulting in large differences in the composition of sludge of different sampling capacities. For example, small capacity sampling can reflect the instantaneous state of sludge, while large capacity sampling can more comprehensively reflect the overall characteristics of sludge. Therefore, it is necessary to take out sludge of two different capacities.

[0006] However, the existing sampling device needs to be disassembled and replaced when sampling sludge of two different capacities. It is difficult to analyze and study samples of different capacities taken from sludge of the same period, which makes sampling more troublesome and reduces sampling efficiency. Therefore, it is necessary to provide a sludge sampling mechanism to solve the above problems.

[0007] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information that does not constitute prior art. SUMMARY

[0008] Based on the above problems existing in the prior art, the present application solves the problem of providing a sludge sampling mechanism, which can take out sludge of two different capacities without disassembling and replacing the storage barrel, thereby speeding up the sampling speed and saving time.

[0018] Further, one end of the sampling pipe close to the conveying pipe is provided as an arc surface.

[0030] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0031] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work should fall within the protection scope of the present application.

[0032] As Figures 1-2 ​​As shown, this application provides a sludge sampling mechanism, including a conveying pipe 1 for conveying sludge. A fixed pipe 11 is provided on one side of the conveying pipe 1, and a sampling mechanism 2 is provided inside the fixed pipe 11. The sampling mechanism 2 has a sampling tube 24 slidably connected inside the fixed pipe 11. The end of the sampling tube 24 near the conveying pipe 1 is set as an arc surface. In this application, when the sampling tube 24 is in the initial position, the arc surface cooperates with the conveying pipe 1 to form a complete pipe, so the sludge will not enter the fixed pipe 11.

[0033] To facilitate the adjustment of the position of the sampling tube 24, a connecting frame 21 is fixedly installed at the other end of the fixed tube 11. A driving shaft 23 is slidably connected at the axis of the connecting frame 21, and the driving shaft 23 passes through the connecting frame 21 and is located inside the fixed tube 11. The end of the driving shaft 23 near the fixed tube 11 is fixedly connected to the sampling tube 24.

[0034] Meanwhile, a drive cylinder 22 is fixedly installed at the other end of the connecting frame 21. The output shaft of the drive cylinder 22 passes through the connecting frame 21 and is fixedly connected to the other end of the drive shaft 23. Therefore, starting the drive cylinder 22 can push the drive shaft 23 to make the sampling tube 24 slide in the fixed tube 11 and enter the delivery pipeline 1 for sampling, so that no operator needs to manually sample.

[0035] like Figures 2-3 As shown, in order to facilitate sampling, the sampling tube 24 has a flow channel 241 inside. The flow channel 241 has an inlet 242 at one end near the conveying pipe 1. In this application, the inlet 242 is aligned with the pipe opening of the conveying pipe 1. It should be noted that when the sampling tube 24 is in the initial state, the inlet 242 is located inside the sampling tube 24 and does not enter the conveying pipe 1.

[0036] Meanwhile, the lower end of the fixed pipe 11 is connected to the discharge pipe 12, and the other end of the flow channel 241 is provided with a discharge port 243. The discharge port 243 is in the same direction as the opening of the discharge pipe 12. It should be noted that when the sampling pipe 24 is in the initial state, the discharge port 243 is located inside the sampling pipe 24 and is not aligned with the discharge pipe 12.

[0037] In order to simultaneously remove two sludge volumes of different sizes, a collection mechanism 3 is provided below the feed pipe 12. The collection mechanism 3 has a three-way valve 31 connected to the lower end of the feed pipe 12. A switch handle 32 is provided on one side of the three-way valve 31, and the flow position of the three-way valve 31 can be controlled by the switch handle 32.

[0038] like Figure 1As shown, one side pipe of the three-way valve 31 is connected with the first conveying pipe 33, the lower end of the first conveying pipe 33 is threadedly connected with the first sampling box 34, the first sampling box 34 is detachable, meanwhile, the other end pipe of the three-way valve 31 is connected with the second conveying pipe 35, the lower end of the second conveying pipe 35 is threadedly connected with the second sampling box 36, the second sampling box 36 is detachable, in the application, the volumes of the first sampling box 34 and the second sampling box 36 are inconsistent.

[0039] In summary: if two different volumes of sludge in conveying need to be taken out, at this time, the three-way valve 31 is adjusted to be in communication with the first conveying pipe 33 and the second conveying pipe 35, then the driving cylinder 22 is started to push the sampling pipe 24 into the conveying pipe 1, at this time, the discharge port 243 is located above the discharge pipe 12;

[0040] At this time, the sludge in conveying enters the flow channel 241 through the inlet port 242, and enters the discharge pipe 12 through the discharge port 243, and then flows to the first conveying pipe 33 and the second conveying pipe 35, until the first sampling box 34 and the second sampling box 36 are filled, so that when two different volumes of sludge are taken out, the storage barrel does not need to be disassembled and replaced, the sampling speed is accelerated, time is saved, the same period of sludge is taken out to analyze and study different volumes of samples, and the sampling efficiency is improved.

[0041] If sludge samples of different time periods need to be taken out, at this time, the three-way valve 31 can be adjusted to be connected to the first conveying pipe 33, the first sampling box 34 is used for sampling first, then after the second sampling time arrives, the three-way valve 31 is adjusted to be connected to the second conveying pipe 35, so as to sample the second sampling box 36.

[0042] In the application, single sampling and common sampling can be realized, and different sampling boxes can be replaced during sampling, so as to improve the sampling efficiency.

[0043] The above only describes the preferred embodiments of the application and is not used to limit the application, for those skilled in the art, the application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
