Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of detector, especially a harmful substance detector for sludge treatment. BACKGROUND

[0002] With the rapid development of industry and the acceleration of urbanization, the production of sludge is increasing day by day. These sludge often contains a large amount of harmful substances, such as heavy metals, pathogenic bacteria, persistent organic pollutants, etc. If not properly handled, these harmful substances will enter the ecological system through soil, water and other ways, causing serious threat to the environment and human health. In order to realize the safe and effective treatment of sludge, it is the key prerequisite to accurately detect the types and contents of harmful substances. Therefore, high-precision and high-adaptive detection instruments are needed to quickly and accurately detect sludge of different sources and different properties. At the same time, since the sludge samples are usually placed in containers of different sizes and shapes, the detection instrument also needs to have good sample fixing ability to ensure the stability and accuracy of the detection process.

[0003] The traditional sludge harmful substance detector has great limitations in sample fixing. Its mechanical structure mainly adopts fixed-size sample groove or simple clamping device. The sample groove is usually designed according to the size of standard container. Once the size of the sample container does not match the standard size, it cannot be effectively placed and fixed.

[0004] However, the prior art has the problem of being unable to effectively fix containers of different sizes. Because the sample fixing structure of the traditional detection instrument lacks flexibility and self-adaptive ability, when encountering non-standard size containers, the containers are prone to shaking, shifting and other situations during the detection process, which not only causes the relative position between the detection head and the sample to change, affecting the accuracy and repeatability of the detection, but also easily causes the sample to splash, causing pollution to the detection environment and waste of the sample. Therefore, a harmful substance detector for sludge treatment is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0034] Fixed assembly includes clamping block 6, clamping block 6 is connected in the inside of support seat 4 slidingly, the inside of support seat 4 is provided with sliding slot 5, clamping block 6 is connected in the inside of sliding slot 5 slidingly, when needing to fix the container, clamping block 6 slides under the guidance of sliding slot 5, clamps the outer wall of container, support seat 4 inside fixedly connected with connecting column 7, clamping block 6 is connected in the outer wall of connecting column 7 slidingly, connecting column 7 outer wall is equipped with spring one 8, spring one 8 both ends are fixedly connected in the inside of support seat 4 and clamping block 6 respectively, spring one 8 will be compressed after clamping block 6 is stressed, and quickly restores to the original state after the external force is released, ensure that clamping block 6 firmly clamps the container.

[0035] Specifically, when using the harmful substance detector, first, the container containing sludge needs to be placed in the support seat 4 inside the detection instrument 1, when the container is placed, the outer wall of the container will cause a certain extrusion to the clamping block 6 inside the support seat 4, so that the clamping block 6 is stressed and starts to slide, when the clamping block 6 is stressed, it will slide into the sliding slot 5 inside the support seat 4, after the clamping block 6 slides into the sliding slot 5, it will compress the spring one 8 on one side, the spring one 8 has strong restoring force and can quickly restore to the original state after being compressed, ensuring that the clamping block 6 firmly clamps the container, when the container is placed, the elastic action of the spring one 8 enables the clamping block 6 to firmly clamp the outer wall of the container, fixing the position of the container and preventing it from shifting during the detection process.

[0036] With reference to Figure 1 , Figure 2 and Figure 4The connecting assembly comprises a joint 10 and a clasp 12. The joint 10 is fixedly connected to the inside of the detection instrument 1. The clasp 12 is fixedly connected to the outside of the joint 10, and serves as a support and a connection. The hollow column 11 is fixedly connected to the top of the detection head 9. The hollow column 11 is slidably connected to the outside of the joint 10. The collar 13 is fixedly connected to the inside of the hollow column 11. The collar 13 is slidably connected to the outside of the joint 10. The sliding sleeve 14 is slidably connected to the outside of the hollow column 11. The sliding sleeve 14 is internally provided with an air slot 16. The spring 15 is sleeved on the outside of the hollow column 11. The spring 15 is arranged in the air slot 16. The spring 15 is fixedly connected to the inside of the sliding sleeve 14 and the hollow column 11.

The limiting slot 18 is internally provided in the sliding sleeve 14. The clamping bead 17 is slidably connected to the inside of the limiting slot 18.

[0037] Specifically, when the detection head 9 needs to be disassembled and maintained, first, the sliding sleeve 14 on the outside of the hollow column 11 above the detection head 9 needs to be actuated to slide on the outside of the hollow column 11. The sliding sleeve 14 serves to compress the spring 15 inside by sliding, so as to release the clamping bead 17 inside the hollow column 11. When the spring 15 is compressed, the sliding sleeve 14 releases the clamping bead 17, so that the detection head 9 and the hollow column 11 can be removed from the outside of the joint 10 inside the detection instrument 1. When installed, the user only needs to insert the hollow column 11 into the outside of the joint 10, so as to ensure that the connection is tightly connected, and prevent the normal use of the instrument from being affected due to looseness. When the connection is completed, the spring 15 is automatically restored to reset the sliding sleeve 14. At this time, the sliding sleeve 14 exerts pressure on the clamping bead 17, so that the clamping bead 17 is clamped into the clasp 12 on the outside of the joint 10 again, so as to complete the fixing work. The disassembly and assembly process becomes more simple and fast, and the maintenance efficiency and convenience of the equipment are improved.

[0038] Working principle: when using the harmful substance detector, first, the container containing sludge is placed in the support seat 4 inside the detection instrument 1, in this process, the container outer wall will cause extrusion to the clamping block 6 inside the support seat 4, so that the clamping block 6 is forced to slide into the sliding slot 5 inside the support seat 4, at the same time, the clamping block 6 compresses the spring 8 on one side, when the container is placed, through the elasticity of the spring 8 itself, in turn drives the clamping block 6 to clamp the container outer wall to fix it, then through the detection head 9 inside the detection instrument 1 to detect the sludge in the container, so as to achieve the effect of effectively fixing different size containers, when the detection head 9 needs to be disassembled and maintained, first, the sleeve 14 on the outer wall of the hollow column 11 is actuated, so that it slides on the outer wall of the hollow column 11, at the same time, the sleeve 14 compresses the spring 15 inside, so that the sleeve 14 releases the clamping ball 17 inside the hollow column 11, at this time, the detection head 9 and the hollow column 11 are taken off from the outer wall of the joint 10 inside the detection instrument 1 to complete the disassembly, when installing, only need to insert the hollow column 11 into the outer wall of the joint 10, after connection, loosen the sleeve 14, through the spring 15 unloading, in turn drives the sleeve 14 to reset, so that the sleeve 14 exerts pressure on the clamping ball 17, in turn makes the clamping ball 17 clamp on the clamping ring 12 on the outer wall of the joint 10 to complete the fixation, so as to achieve the effect of convenient disassembly and maintenance of the detection head 9.
