Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Please see Figure 1-7 A sludge dewatering and drying monitoring device with a sampling and detection apparatus includes a fixed plate 1. A sampling mechanism 2 is connected to the bottom end of the fixed plate 1. The sampling mechanism 2 includes a triangular track box 201, which is installed at the bottom end of the fixed plate 1. Scrapers 202 are evenly distributed on the triangular track box 201. A sludge inlet 203 is provided on one side of the triangular track box 201, and a sludge outlet 204 is provided on the other side. A guide is installed on the outer side of the sludge outlet 204. The bottom surface of the material support plate 205 is symmetrically provided with fixing holes 206. The triangular track box 201 is installed above the conveyor belt of the sludge dewatering and drying integrated machine through the fixing plate 1. When the triangular track box 201 is started, under the action of the scraper 202, the dewatered and dried sludge can be sampled through the sludge inlet 203 and discharged through the sludge outlet 204 onto the material support plate 205 for collection. This realizes the function of rapid sludge sampling, which is convenient for subsequent sludge testing.

[0036] See Figure 3 and Figure 4 A heating mechanism 3 is connected to one side of the sampling mechanism 2. The heating mechanism 3 includes a collection cylinder 301. The top of the collection cylinder 301 is connected to a fixing hole 206. A fixing circular plate 302 is provided at the top of the inside of the collection cylinder 301. An electric heating coil 303 is connected to the bottom surface of the fixing circular plate 302. A rotating head 304 is rotatably connected to the top surface of the fixing circular plate 302. Grinding plates 305 are evenly arranged on the outer side of the rotating head 304. The collection cylinder 301 is connected through the fixing hole 206 so that the collection cylinder 301 can collect the sampled sludge. Under the rotation of the rotating head 304 and the grinding plate 305, the falling sludge can be crushed. In conjunction with the electric heating coil 303, the sludge can be heated to accelerate the evaporation of water in the sludge, which is convenient for the subsequent detection of the remaining water content in the sludge.

[0037] See Figure 4 In order to accelerate the evaporation efficiency of water in sludge by the electric heating coil 303, the electric heating coil 303 is spiral in shape. A drive motor 9 is connected to the center of the bottom end of the fixed circular plate 302. The output end of the drive motor 9 is fixedly connected to the grinding plate 305. The drive motor 9 can provide power for the rotation of the grinding plate 305.

[0038] See Figure 6 A detection mechanism 4 is connected to one side of the heating mechanism 3. The detection mechanism 4 includes a test tube 401, which is connected to one side of the collection cylinder 301. A gas pipe 402 is connected between the top of the test tube 401 and the outside of the collection cylinder 301. A water level sensor 403 is installed on one side of the inside of the test tube 401, and a reagent rod 404 is installed on the other side of the inside of the test tube 401. The reagent rod 404 has a through hole, and dry copper sulfate reagent particles are placed inside the reagent rod 404. A convex lens 405 is embedded on the outside of the test tube 401 at the position corresponding to the reagent rod 404. The collection cylinder 3 is heated through the gas pipe 402. The water vapor evaporated from the sludge in test tube 401 is discharged into the test tube 401 for condensation and liquefaction. By activating the water level sensor 403 in one test tube 401, the water content of the sludge can be detected. The liquefied water from the sludge is absorbed by the reagent rod 404 in another test tube 401. The dried copper sulfate reagent particles in the reagent rod 404 change from white to blue upon contact with water. Combined with the magnification effect of the convex lens 405, it is easy for the staff to observe. Thus, the function of detecting the internal water content of the sludge after dewatering and drying is realized, which meets the device's need for feedback monitoring of the water content of the sludge after dewatering and drying.

[0039] See Figure 7 The bottom of the collection cylinder 301 is connected to a collection mechanism 5, which includes a collection hopper 501 connected to the bottom of the collection cylinder 301. A drawer 502 is slidably connected inside the collection hopper 501. A solenoid valve plate 503 is provided at the bottom of the collection cylinder 301. After the test is completed, the solenoid valve plate 503 can be activated to discharge the sludge into the solenoid valve plate 503 inside the collection hopper 501 for unified collection and treatment, which facilitates the reuse of the collection cylinder 301.

[0040] See Figure 2 An electronic control board 6 is connected to one side of the triangular track box 201. The electronic control board 6 can control the start and stop of the triangular track box 201, the electric heating coil 303, the rotating head 304, the water level sensor 403, the drive motor 9 and the solenoid valve plate 503. The amount of sludge sampled can be controlled by controlling the sludge discharge port 204 through the electronic control board 6.

[0041] See Figure 5 The top of the collection cylinder 301 is connected to a filter screen 8, and there are two collection cylinders 301. The stones can be filtered out through the filter screen 8, reducing the impact of the stones in the sludge on the device.

[0042] See Figure 2 A ramp 7 is provided on one side of the inside of the guide plate 205, which speeds up the falling speed of the sampled sludge.

[0043] See Figure 7 In order to facilitate the downward discharge of sludge in the collection cylinder 301, the bottom of the collection cylinder 301 is designed as a funnel shape.

[0044] In use: The triangular track box 201 is installed above the conveyor belt of the sludge dewatering and drying integrated machine via the fixing plate 1. When the triangular track box 201 is started, under the action of the scraper 202, the dewatered and dried sludge is sampled through the sludge inlet 203 and discharged through the sludge outlet 204 onto the guide support plate 205 for collection. Then, the collection cylinder 301 is connected through the fixing hole 206, allowing the collection cylinder 301 to collect the sampled sludge. The rotating head 304 and grinding plate 305 crush the falling sludge, and the electric heating coil 303 heats the sludge, accelerating the evaporation of moisture. Finally, the sludge in the collection cylinder 301 is discharged through the air pipe 402. The water vapor from the sludge evaporation is discharged into the test tube 401 for condensation and liquefaction. By activating the water level sensor 403 in one test tube 401, the water content of the sludge can be detected. In another test tube 401, the liquefied water from the sludge is absorbed by the reagent rod 404. The dried copper sulfate reagent particles in the reagent rod 404 change from white to blue upon contact with water. Combined with the magnification effect of the convex lens 405, this facilitates observation by the staff, meeting the device's requirement for feedback monitoring of the water content of the sludge after dewatering and drying. Finally, activating the solenoid valve plate 503 discharges the sludge into the solenoid valve plate 503 inside the collection hopper 501 for unified collection and treatment, facilitating the reuse of the collection cylinder 301.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
