Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater detection technology, specifically a sample separation device. Background Technology
[0002] Wastewater testing is the process of analyzing and measuring various physical, chemical, and biological parameters in wastewater. These tests aim to assess the nature and composition of wastewater and its potential impact on the environment and human health. The main purpose of wastewater testing is to ensure the effectiveness and compliance of wastewater treatment processes. Through testing, harmful substances in wastewater can be detected in a timely manner, allowing for appropriate treatment measures to be taken to prevent pollution of the environment and ecosystems.
[0003] Currently, wastewater testing requires the separation of wastewater samples, which necessitates the use of separation devices to filter and remove impurities. However, with prolonged use, some existing separation devices tend to accumulate suspended solids, floating matter, and colloids on the filter screen, forming a filter cake that reduces filtration efficiency and consequently affects the wastewater sample separation efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a sample separation device to solve the problem that debris on the surface of the filter screen of some separation devices affects the separation efficiency of sewage samples during long-term use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample separation device, including a separation tank, and further comprising:
[0006] The PLC controller is located on the outside, the sealing cover is located on the top, the inlet pipe is connected to the top of the sealing cover, and the outlet pipe is located inside.
[0007] The separation assembly is located inside the separation tank. The separation assembly includes a manifold that is fixedly connected to the inner wall of the separation tank. A first filter cylinder is provided on the top of the manifold, a second filter cylinder is provided inside the first filter cylinder, and a positioning rod is fixedly connected to the bottom of the first filter cylinder.
[0008] Preferably, a positioning plate is fixedly connected to the inner wall of the manifold, and a positioning hole is opened inside the positioning plate to cooperate with the positioning rod. The inner wall of the positioning hole is slidably connected to the outer side of the positioning rod.
[0009] Preferably, the top of the outlet pipe is connected to the bottom of the manifold, a valve is provided on the outside of the outlet pipe, and a motor is fixedly connected to the bottom of the inner cavity of the first filter cylinder.
[0010] Preferably, the output end of the motor is fixedly connected to a positioning plate, and a fixing tube is fixedly connected inside the positioning plate.
[0011] Preferably, a spring is welded to the bottom of the inner cavity of the fixed tube, and a screw is welded to the top of the spring. The outer side of the screw is slidably connected to the inner wall of the fixed tube.
[0012] Preferably, a side plate is fixedly connected to the outer side of the screw, and the number of side plates is set to two.
[0013] Preferably, the outer side of the screw is threaded with a connecting pipe, and the top of the connecting pipe is fixedly connected to the bottom of the second filter cylinder.
[0014] Preferably, the bottom of the second filter cartridge is fixedly connected to a plug rod, and the positioning plate has an insertion hole inside that cooperates with the plug rod. The inner wall of the insertion hole is slidably connected to the outer side of the plug rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention, through the setting of a separation component, allows for the separation of wastewater test samples. First, the sample enters the separation tank through the inlet pipe, and then enters the second filter cartridge through the inlet pipe. After sample separation, the operator pulls the first filter cartridge, causing the top rod to slide inside the positioning hole, thereby disengaging the first and second filter cartridges from the separation tank. Then, the operator pulls the second filter cartridge, causing the insertion rod to disengage from the insertion hole. Simultaneously, the connecting pipe drives the screw to move inside the fixed pipe, causing the spring to extend. The operator then rotates the second filter cartridge, causing the connecting pipe to rotate outside the screw, thereby disengaging the connecting pipe from the outside of the screw. This allows the operator to detach the second filter cartridge from the first filter cartridge, facilitating separate cleaning of the first and second filter cartridges and preventing residual debris from affecting the sample separation effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 As shown, a sample separation device includes a separation tank 1. By setting the separation tank 1, wastewater samples can be separated under the action of the separation tank 1, so that impurities in the sample are removed from the wastewater sample. The device also includes:
[0024] The PLC controller 2, located on the outside, controls the various electronic components inside the device. The sealing cover 3, located on the top, prevents sample splashing during separation. The inlet pipe 4, connected to the top of the sealing cover 3, facilitates the separation and transport of wastewater samples by staff. The outlet pipe 5, located inside, facilitates the unified collection and processing of the separated wastewater samples by staff.
[0025] The separation component 6, installed inside the separation tank 1, processes wastewater samples, removing impurities. The separation component 6 includes a manifold 61 fixedly connected to the inner wall of the separation tank 1. The manifold 61 allows water in the sample to collect and flow, facilitating the collection and processing of the separated samples. A first filter cylinder 62 is installed at the top of the manifold 61, and a second filter cylinder 63 is installed inside the first filter cylinder 62. The first and second filter cylinders 62 and 63 facilitate the separation of wastewater samples. Both the first and second filter cylinders 62 and 63 contain filter screens to filter impurities from the samples. A positioning rod 64 is fixedly connected to the bottom of the first filter cylinder 62, allowing it to be installed at a designated position within the manifold 61.
[0026] refer to Figure 2 and Figure 3 As shown, a positioning plate 7 is fixedly connected to the inner wall of the manifold 61. By setting the positioning plate 7, the position of the first filter cylinder 62 can be positioned, which facilitates the disassembly and assembly of the first filter cylinder 62 by the staff. The positioning plate 7 has a positioning hole 8 inside that works with the positioning rod 64. By setting the positioning hole 8, the positioning rod 64 can enter the interior of the positioning hole 8, so that the first filter cylinder 62 can be placed in the designated position. The inner wall of the positioning hole 8 is slidably connected to the outer side of the positioning rod 64.
[0027] The top of the outlet pipe 5 is connected to the bottom of the manifold 61. By setting the manifold 61, the separated wastewater test samples can be collected and processed in a unified manner. A valve 9 is set on the outside of the outlet pipe 5. By setting the valve 9, the opening and closing of the outlet pipe 5 can be controlled. A motor 10 is fixedly connected to the bottom of the inner cavity of the first filter cylinder 62. By setting the motor 10, the second filter cylinder 63 can be rotated by the positioning plate 11, so that the impurities in the wastewater test sample are collected at the bottom of the inner cavity of the second filter cylinder 63 under the action of centrifugal force.
[0028] The output end of the motor 10 is fixedly connected to a positioning plate 11. By setting the positioning plate 11, it is convenient for the staff to disassemble and position the second filter cartridge 63. The positioning plate 11 is fixedly connected to a fixing tube 12. By setting the fixing tube 12, the screw 14 can move inside the fixing tube 12, and the spring 13 can be compressed or extended.
[0029] A spring 13 is welded to the bottom of the inner cavity of the fixed tube 12. By setting the spring 13, the screw 14 can be reset after movement under the action of the spring force of the spring 13. A screw 14 is welded to the top of the spring 13. By setting the screw 14, the second filter cylinder 63 can be firmly connected to the positioning plate 11 under the action of the screw 14. The outer side of the screw 14 is slidably connected to the inner wall of the fixed tube 12.
[0030] refer to Figure 2 and Figure 4 As shown, a side plate 15 is fixedly connected to the outside of the screw 14. By setting the side plate 15, the outside of the side plate 15 is slidably connected to the inside of the fixed tube 12, thereby limiting the movement range of the screw 14 and preventing the screw 14 from leaving the inside of the fixed tube 12. The number of side plates 15 is set to two.
[0031] The screw 14 is threaded with a connecting pipe 16. By setting the connecting pipe 16, it can be connected to the screw 14, so that the second filter cylinder 63 can be firmly connected to the positioning plate 11. The top of the connecting pipe 16 is fixedly connected to the bottom of the second filter cylinder 63.
[0032] The bottom of the second filter cylinder 63 is fixedly connected to a rod 17. The length of the rod 17 is less than the length of the connecting tube 16. After the connecting tube 16 is initially connected to the screw 14, the connecting tube 16 is pulled and the second filter cylinder 63 is rotated. After the connecting tube 16 moves to the designated position, the second filter cylinder 63 is released. Then, under the elastic force of the spring 13, the screw 14 moves, so that the rod 17 enters the interior of the insertion hole 18. This allows the second filter cylinder 63 to be tightly connected to the positioning plate 11. The positioning plate 11 has an insertion hole 18 inside that works with the rod 17. The inner wall of the insertion hole 18 is slidably connected to the outer side of the rod 17.
[0033] Working principle: When the operator uses this device to separate wastewater samples, the wastewater sample first enters the second filter cylinder 63 through the inlet pipe 4. Then, the motor 10 is started, which drives the second filter cylinder 63 to rotate inside the first filter cylinder 62. This causes impurities in the wastewater sample to collect at the bottom of the second filter cylinder 63. Simultaneously, the wastewater in the sample, under the action of the filter screens inside the first and second filter cylinders 62 and 63, enters the manifold 61. Finally, the separated wastewater is collected through the outlet pipe 5. When it is necessary to disassemble and assemble the second filter cartridge 63 and the first filter cartridge 62, pull the first filter cartridge 62, thereby causing the positioning rod 64 to disengage from the positioning hole 8, so that the first filter cartridge 62 and the second filter cartridge 63 disengage from the separation tank 1. Then pull the second filter cartridge 63, causing the insertion rod 17 to disengage from the insertion hole 18, and at the same time causing the spring 13 to extend. Then rotate the second filter cartridge 63, thereby causing the connecting pipe 16 to disengage from the screw 14, so that the second filter cartridge 63 can disengage from the first filter cartridge 62, thus making it easier for the staff to clean the first filter cartridge 62 and the second filter cartridge 63.
