Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage treatment agent inspection and sampling device. Background Art
[0002] Testing of wastewater treatment chemicals is a crucial step in ensuring the effectiveness and safety of the wastewater treatment process. By testing chemicals, we can ensure they meet relevant standards and guarantee the effectiveness of wastewater treatment.
[0003] In the prior art, medicines are sampled by electric pumping devices. Since the types of medicines to be tested are not single, different solutions need to be sampled multiple times. At this time, the corresponding medicine is likely to remain in the sampling device after one sampling. Therefore, the sampling device needs to be cleaned and dried before a second sampling can be performed. The whole process is relatively time-consuming. If multiple electric pumping devices are used at the same time, it is not necessary and will increase the cost of use.
[0004] In view of the above-mentioned existing technical problems, a sewage treatment agent inspection sampling device is proposed to solve the above-mentioned problems. Utility Model Content
[0005] In response to the shortcomings of the existing technology, the present application provides a sewage treatment agent inspection sampling device with a detachable separation structure, which facilitates and quickly replaces the inner cavity wall of the sampling device, and the alternating cleaning does not affect the sampling efficiency of the agent.
[0006] To achieve the above objectives, the present application provides the following technical solutions: a sewage treatment agent inspection sampling device, comprising an outer tube and an inner tube detachably connected to the outer tube, wherein the top of the outer tube is provided with an electric structure, a piston rod extends within the electric structure, and a piston head corresponding to the piston rod is slidably mounted within the inner tube;
[0007] A first thread segment is integrally connected to the bottom end of the outer tube, and a second thread segment corresponding to the first thread segment is fixedly installed on the outer extension of the bottom end of the inner tube;
[0008] A threaded shaft is fixedly mounted on the bottom end of the piston rod, and a threaded hole for connecting the threaded shaft is provided on the top of the piston head.
[0009] Furthermore, a stabilizing disk is fixedly mounted on the bottom end of the piston rod, and a sink groove for the stabilizing disk to be embedded in the top of the piston head is provided, and the stabilizing disk is embedded in the sink groove.
[0010] Furthermore, a guide bar is fixedly mounted on the inner wall of the inner tube, and a groove for the guide bar to slide is provided on the outside of the piston head.
[0011] Furthermore, the length of the threaded shaft corresponds to the length of the second threaded section, and a suction pipe is integrally extended from the lower end of the inner tube.
[0012] Furthermore, the electric structure includes a motor fixedly mounted on the top of the outer tube, a worm fixed on the power end of the motor, and a worm wheel rotatably mounted on the outer tube.
[0013] Furthermore, the worm wheel is engaged with the worm, and the middle part of the worm wheel is penetrated by the piston rod and threadedly connected.
[0014] Furthermore, a stroke tube is fixedly connected to the electric structure, one end of the piston rod extends into the stroke tube, and one end of the piston rod is fixedly connected to a limit plate that is slidably connected to the stroke tube.
[0015] Furthermore, the limiting plate and the travel tube are both rectangular.
[0016] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0017] The sewage treatment agent inspection sampling device is configured to divide the original sampling tube into an inner tube and an outer tube. The inner tube and the outer tube are connected by threads, so that the inner tube can be disassembled in time after sampling, thereby making use of the electric structure on the outer tube and the replaced inner tube to adapt to secondary sampling. The inner tubes between two samplings are independent of each other, and multiple groups of inner tubes can be prepared and replaced between multiple samplings, thereby significantly improving the sampling efficiency.

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0024] See also Figures 1 to 4 In this embodiment, a sewage treatment agent inspection and sampling device includes an outer tube 1 and an inner tube 5 detachably connected to the outer tube 1. An electric structure 2 is provided on the top of the outer tube 1, a piston rod 3 extends inside the electric structure 2, and a piston head 7 corresponding to the piston rod 3 is slidably installed in the inner tube 5.
[0025] In a specific implementation, the inner tube 5 and the piston head 7 are directly disassembled relative to the outer tube 1 and replaced with a clean inner tube 5, so that secondary sampling can be achieved without cleaning the sampling device.
[0026] In this embodiment, a first threaded segment 101 is integrally connected to the bottom end of the outer tube 1, and a second threaded segment 501 corresponding to the first threaded segment 101 is fixedly installed on the outer extension of the bottom end of the inner tube 5. By threading the first threaded segment 101 and the second threaded segment 501 together, the connection and assembly of the inner tube 5 relative to the outer tube 1 can be achieved.
[0027] It is understandable that a sealing gasket may be further provided between the second threaded section 501 and the outer tube 1 to improve the tightness of the connection between the inner tube 5 and the outer tube 1 .
[0028] It should be noted that a threaded shaft 9 is fixedly installed on the bottom end of the piston rod 3, and a threaded hole 703 for connecting the threaded shaft 9 is opened on the top of the piston head 7. The threaded shaft 9 and the threaded hole 703 are connected to each other, so that the piston head 7 can be assembled with the piston rod 3.
[0029] Preferably, a stabilizing disk 10 is fixedly mounted on the bottom end of the piston rod 3, and a recess 702 is provided on the top of the piston head 7 for the stabilizing disk 10 to be embedded in. The stabilizing disk 10 embedded in the recess 702 can improve the connection stability between the piston rod 3 and the piston head 7.
[0030] In this embodiment, a guide bar 704 is fixedly installed on the inner wall of the inner tube 5, and a groove 701 is provided on the outside of the piston head 7 for the guide bar 704 to slide. Through the relative sliding of the guide bar 704 and the groove 701, the rotation of the piston head 7 relative to the inner tube 5 is restricted, so that the piston head 7 can be directly built into the inner tube 5 and rotatably docked with the threaded shaft 9.
[0031] It can be understood that the length of the threaded shaft 9 corresponds to the length of the second threaded section 501 , so that the piston head 7 and the inner tube 5 can be assembled synchronously.
[0032] In this embodiment, a suction tube 6 is integrally extended from the lower end of the inner tube 5 , and the medicine is extracted into the inner tube 5 through the suction tube 6 .
[0033] It should be noted that the electric structure 2 includes a motor 201 fixedly mounted on the top of the outer tube 1 , a worm 202 fixed on the power end of the motor 201 , and a worm gear 203 rotatably mounted on the outer tube 1 .
[0034] Preferably, the worm wheel 203 is engaged with the worm 202, and the rotation of the worm 202 can drive the worm wheel 203 to rotate. At the same time, the middle part of the worm wheel 203 is penetrated by the piston rod 3 and threadedly connected. At this time, the rotation of the worm wheel 203 can drive the piston rod 3 to move relative to the outer tube 1.
[0035] In this embodiment, the electric structure 2 is further fixedly connected to a stroke tube 4 , one end of the piston rod 3 extends into the stroke tube 4 , and one end of the piston rod 3 is fixedly connected to a limit plate 8 slidably connected to the stroke tube 4 .
[0036] Preferably, the limiting plate 8 and the stroke tube 4 are both rectangular, and the relative sliding of the limiting plate 8 and the stroke tube 4 can limit the rotation of the piston rod 3.
[0037] The working principle of the above embodiment is:
[0038] By controlling the motor 201, the motor 201 drives the worm 202 to rotate. The worm 202, while meshing with the worm wheel 203, pulls the worm wheel 203 to rotate. At this time, the piston rod 3 is threadedly engaged with the worm wheel 203, thereby sliding and changing its position relative to the outer tube 1, so that the piston head 7 connected to the end of the piston rod 3 slides in the inner tube 5 to generate negative pressure to extract the sewage treatment agent.
[0039] After one sampling, by rotating the inner tube 5 relative to the outer tube 1, the connection between the inner tube 5 and the outer tube 1, namely the first threaded segment 101 and the second threaded segment 501, is disengaged from each other, so that the inner tube 5 can slide away from the outer tube 1. At this time, the rotation of the piston head 7 is restricted by the guide bar 704, so that the piston head 7 rotates relative to the threaded shaft 9 at the lower end of the piston rod 3, that is, the piston head 7 is also disengaged from the connection with the piston rod 3. A clean inner tube 5 is replaced and sampling can be carried out again.
