Description

Technical Field

[0001] This utility model relates to the field of liquid-solid separation technology of ash analyzers, and in particular to a liquid-solid separation device for slurry ash analyzers. Background Technology

[0002] Slurry refers to a liquid mixture formed in industrial production by adding water and other auxiliary agents to solid raw materials such as ores and clays to extract target elements. Ash is the inorganic component remaining after a substance has undergone high-temperature combustion or ablation, mainly including inorganic salts and oxides. Ash analyzers, employing a dual gamma-ray penetration method, can eliminate the influence of factors such as coal porosity and particle size, rapidly determining the ash content and calorific value of coal.

[0003] An existing solid-liquid separation device for mineral slurry composition detection (Announcement No.: CN220251502U) can directly extract mineral slurry from the sampling port and quantitatively add it into the separation tank through a suction pump in the solid-liquid separation unit, eliminating the need for manual mineral slurry sample collection and reducing the labor intensity of staff. However, directly extracting mineral slurry from the sampling port into the separation tank for processing is prone to pipe blockage due to the presence of large impurities such as stones in the slurry, which is detrimental to the solid-liquid separation effect and detection accuracy. Furthermore, it requires the use of a filter screen and activated carbon adsorption rods, which necessitates the separate disassembly and cleaning of the filter screen and activated carbon rods, making the operation cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a liquid-solid separation device for a slurry ash analyzer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid-solid separation device for a slurry ash analyzer includes a workbench, an interception box, and a filter cartridge. The ash analyzer body is installed on one side of the workbench. A separation tank is provided between the interception box and the filter cartridge. A fixing frame is embedded inside the interception box, and a filter bag is fixedly installed inside the fixing frame. A protruding strip is fixedly provided inside the filter cartridge, and a slot is embedded in the protruding strip. A filter element is fixedly installed in the slot. A stirring device is installed inside the separation tank by fasteners.

[0007] As a further embodiment of this utility model, a second conveying pipe is fixedly provided between the top of the interception box and the separation tank, a first conveying pipe is fixedly provided between the side wall of the separation tank and the filter cylinder, and a first discharge pipe is fixedly provided at the bottom of the filter cylinder.

[0008] As a further embodiment of this utility model, a feed valve 2 is fixedly provided on the first conveying pipe, a discharge valve 1 is fixedly installed on the first discharge pipe, and a cover plate 2 is fitted into the top of the filter cylinder, the cover plate 2 being connected to the filter cylinder by a bolt 1.

[0009] As a further embodiment of this utility model, a sealing ring is fixedly provided on the inner wall of the cover plate II, a discharge pipe II is fixedly provided at the bottom of the separation tank, and a discharge valve II is fixedly installed on the discharge pipe II.

[0010] As a further embodiment of this utility model, a feed pipe is fixedly provided on the side of the interception box away from the second conveying pipe, and a feed valve is fixedly installed on the feed pipe.

[0011] As a further embodiment of this utility model, a cover plate is fitted and installed on the top of the interception box, and a sealing ring is fixedly provided on the inner wall of the cover plate. The cover plate is connected to the interception box by bolts, and the filter cylinder and the separation tank are fixedly installed on the workbench.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When preparing to test the ash content of mineral slurry, an interception box, filter bags, and fixing frames are installed. The filter bags perform preliminary treatment on the incoming slurry, intercepting larger impurity particles to prevent them from wearing down equipment and clogging pipes. This reduces the workload of the separation tank and improves its separation efficiency. By installing filter elements, filter cartridges, slots, and raised strips, after the separation tank separates the solid and liquid components from the slurry, the filter elements achieve efficient filtration of different impurities in the separated liquid, effectively intercepting residual fine particles and colloids. This reduces the interference of impurities on subsequent testing or use, making it easier for operators to operate and improving work efficiency. Attached Figure Description

[0024] In use, the filter bag 802 performs preliminary treatment on the incoming slurry, intercepting larger impurity particles and reducing the amount of impurities entering the separation tank 5. This helps to reduce the burden on the separation tank 5 during separation. When the filter bag 802 is clogged or damaged, by loosening the bolts 804 in sequence and removing the cover plate 201, the fixing frame 803 can be pulled to move the filter bag 802 out. By setting up the filter element 103, filter cylinder 3, slot 104 and convex strip 105, after the separation tank 5 separates the solid and liquid in the slurry, the filter element 103 can further process the liquid, effectively intercepting residual fine particles and colloids, reducing the interference of impurities on subsequent testing or use. Then, the separated sample is taken to the main body 4 of the ash analyzer for testing, improving work efficiency.

[0025] In this embodiment, a second conveying pipe 801 is fixedly provided between the top of the interception box 2 and the separation tank 5, a first conveying pipe 7 is fixedly provided between the side wall of the separation tank 5 and the filter cylinder 3, and a first discharge pipe 202 is fixedly provided at the bottom of the filter cylinder 3.

[0026] When in use, the stirring device 302 mainly consists of components such as a motor, stirring shaft and stirring paddle, which is used to improve the flow state of the slurry, help the mineral particles to be uniformly suspended and moved, and enable them to be better separated.

[0027] In this embodiment, a feed valve 8 is fixedly installed on the conveying pipe 7, a discharge valve 203 is fixedly installed on the discharge pipe 202, and a cover plate 301 is fitted on the top of the filter cylinder 3. The cover plate 301 is connected to the filter cylinder 3 by bolts 106.

[0028] In use, the filter element 103 is pushed into the filter cylinder 3 so that the bottom protrusion 105 is inserted into the slot 104. Then, each set of bolts 106 is tightened in sequence to fix the cover plate 301 on the filter cylinder 3, thereby completing the installation of the filter element 103.

[0029] In this embodiment, a sealing ring 806 is fixedly provided on the inner wall of the cover plate 301, and a discharge pipe 303 is fixedly provided at the bottom of the separation tank 5. A discharge valve 6 is fixedly installed on the discharge pipe 303.

[0030] When in use, filter element 103 is a composite filter element made of PP cotton and activated carbon, which takes into account both particle interception and adsorption effects. Filter bag 802 is made of polyester.

[0031] In this embodiment, a feed pipe 101 is fixedly provided on the side of the interception box 2 away from the conveying pipe 801, and a feed valve 102 is fixedly installed on the feed pipe 101.

[0032] In use, sealing ring 2 806 is used to enhance the sealing between cover plate 2 301 and filter cylinder 3, while sealing ring 1 805 is used to enhance the sealing effect between cover plate 1 201 and interception box 2.

[0033] In this embodiment, a cover plate 201 is fitted onto the top of the interception box 2, and a sealing ring 805 is fixedly provided on the inner wall of the cover plate 201. The cover plate 201 is connected to the interception box 2 by bolts 804. The filter cylinder 3 and the separation tank 5 are fixedly installed on the workbench 1.

[0034] In use, the filter bag 802 is fixed inside the fixed frame 803, with the opening of the filter bag 802 aligned with the feed pipe 101. Then, the fixed frame 803 is pushed to insert and fit into the inner wall of the interception box 2. Finally, the bolt 804 is tightened to complete the installation of the filter bag 802.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: During slurry ash content detection, the slurry is drawn through the feed pipe 101 connected to an external pipeline and the feed valve 102 is opened, allowing the slurry to enter the interception box 2. The filter bag 802 initially intercepts larger impurity particles in the slurry, reducing the impurities entering the separation tank 5 and improving the separation effect of the separation tank 5. By loosening each set of bolts 804 in sequence and removing the cover plate 201, the fixing frame 803 can be pulled to move the filter bag 802 out, thereby replacing the filter bag 802. The slurry treated by the interception box 2 then enters the separation tank 5. Inside tank 5, the slurry is stirred by stirring device 302 to accelerate separation efficiency. The material is discharged through discharge pipe 202. The feed valve 8 is opened to allow the separated water to enter the filter cartridge 3. The water is further effectively filtered by filter element 103. By utilizing the various materials in filter element 103, the filtration accuracy is effectively improved. Then, the separated sample is taken to the main body 4 of the ash analyzer for testing. When blockage or filtration effect decreases, to ensure production continuity, the staff can loosen each set of bolts 106 in sequence, remove cover plate 301, and pull filter element 103 to disengage the protrusion 105 from the slot 104, thus saving manpower and time costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
