[0025] 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.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A chemical fiber sludge hazardous waste material detection device includes a workbench 1, an X-ray fluorescence spectrometer body 2 installed on the right side of the top of the workbench 1, a drying mechanism 3 fixedly connected to the left side of the top of the workbench 1, and a crushing mechanism 4 fixedly connected to the top of the workbench 1.

[0028] The crushing mechanism 4 includes a support shell 401, a servo motor 402, a discharge pipe 403, a rotating rod 404, several crushing rollers 405, six discharge holes 406, a sleeve 407, a storage tank 408, a cover 409, a pull rod 410, and a return spring 411. The support shell 401 is fixedly connected to the top of the workbench 1. The servo motor 402 is installed on the top of the support shell 401. The discharge pipe 403 is fixedly connected to the left side of the top of the support shell 401. The top of the rotating rod 404 is connected to a connecting shaft via a flat key. The connecting shaft is rotatably connected to the top of the inner side of the support shell 401. The output end of the bottom of the servo motor 402 passes through the support shell 401 and is fixedly connected to the top of the rotating rod 404.

[0029] In this embodiment: the workbench 1 provides a stable mounting platform for the X-ray fluorescence spectrometer body 2, the drying mechanism 3, and the crushing mechanism 4. The X-ray fluorescence spectrometer body 2, as the core detection component, can quickly and accurately perform qualitative and quantitative analysis of heavy metals and other elements in the crushed and dried chemical fiber sludge sample. The support shell 401 supports and limits the servo motor 402, the discharge pipe 403, the rotating rod 404, and the discharge hole 406. The servo motor 402, as the power source, drives the rotating rod 404 and the crushing roller 405 to rotate at high speed, ensuring efficient and thorough crushing of the chemical fiber sludge sample. The discharge pipe 403 guides the sludge sample smoothly into the support shell 401, preventing sample spillage during feeding. The moving rod 404 drives multiple crushing rollers 405 to rotate synchronously, breaking the blocky and agglomerated chemical fiber sludge into fine particles. The discharge hole 406 provides a discharge channel for the crushed sample and can also support and limit the sleeve 407. The sleeve 407 guides and constrains the discharge process to prevent the sample from scattering. The storage tank 408 is used to store the crushed sludge sample. Its large volume can meet the storage needs of multiple test samples. The cover 409 can block the discharge hole 406 when the sludge is crushed. The pull rod 410 can drive the cover 409 to slide down along the sleeve 407 when the sludge sample needs to be removed. The return spring 411 can automatically drive the cover 409 to return to the top of the sleeve 407 after the user has finished collecting the sludge sample.

[0030] Specifically, such as Figure 2 , Figure 3 , Figure 4As shown, the rolling roller 405 is welded to the bottom of the rotating rod 404, the discharge hole 406 is opened at the bottom of the support shell 401, the sleeve 407 is welded to the inner side of the discharge hole 406, the bottom of the sleeve 407 passes through and extends to the bottom of the support shell 401, the storage tank 408 is threadedly connected to the bottom of the sleeve 407, the cover 409 is slidably connected to the inner side of the sleeve 407, the pull rod 410 is welded to the bottom of the cover 409, the bottom of the pull rod 410 passes through the storage tank 408 and extends to the outer side of the bottom of the storage tank 408, the pull rod 410 is slidably connected to the inner side of the storage tank 408, the return spring 411 is sleeved on the surface of the pull rod 410, the top of the return spring 411 is fixedly connected to the bottom of the cover 409, and the bottom of the return spring 411 is fixedly connected to the bottom of the inner side of the storage tank 408.

[0031] Specifically, such as Figure 5 , Figure 6 As shown, the drying mechanism 3 includes a drying chamber 301, a PLC controller 302, a mounting plate 303, six electric fans 304, a fixing plate 305, several ventilation holes 306, several semiconductor heat-conducting plates 307, a storage box 308, and three exhaust holes 309. The drying chamber 301 is fixedly connected to the left side of the top of the workbench 1, and the ventilation holes 306 are opened on the inner side of the fixing plate 305.

[0032] Specifically, such as Figure 5 , Figure 6 As shown, the PLC controller 302 is installed on the left side of the drying chamber 301, the mounting plate 303 is fixedly connected to the bottom of the inner side of the drying chamber 301, the electric fan 304 is installed on the inner side of the mounting plate 303, and the fixing plate 305 is welded to the inner side of the drying chamber 301.

[0033] In this embodiment: By setting up a drying chamber 301 to provide a closed space for sample drying, the contamination of the sample by the external environment is effectively reduced. At the same time, it can better maintain the stability of the internal drying temperature and airflow environment, ensuring uniform drying of the sample and guaranteeing the drying effect. The PLC controller 302 can control the servo motor 402, the electric fan 304, and the semiconductor heat-conducting plate 307. The mounting plate 303 can provide a stable mounting position for the electric fan 304. The airflow generated when the electric fan 304 is running, combined with the heat dissipated by the semiconductor heat-conducting plate 307, forms hot air in the drying chamber 301. The mounting plate 303... 5 is used to install the semiconductor heat-conducting plate 307, and can also support and limit the ventilation hole 306. The ventilation hole 306 allows hot air to flow upward and contact the sludge sample, accelerating the evaporation of moisture in the sample. The semiconductor heat-conducting plate 307 is heated efficiently under the control of the PLC controller 302. The storage box 308 is used to store the sample to be dried. At the same time, the bottom of the storage box 308 is set as a filter screen to facilitate the passage of hot air. The exhaust hole 309 promptly discharges the humid and hot air generated during the drying process, maintaining the air circulation and dry environment inside the drying chamber 301, and preventing moisture from accumulating inside the chamber and affecting the drying effect.

[0034] Specifically, such as Figure 5 , Figure 6 As shown, the semiconductor heat-conducting plate 307 is mounted on the top of the fixed plate 305, the storage box 308 is slidably connected to the top of the inner side of the drying oven 301, and the exhaust hole 309 is opened on the rear side of the top of the drying oven 301.

[0035] Specifically, such as Figure 6 As shown, a dust filter 5 is fixedly connected to the inner side of the exhaust hole 309, and the surface of the dust filter 5 is coated with an anti-corrosion coating.

[0036] In this embodiment: by setting up a dust filter 5, dust, impurities and other particles can be effectively intercepted from entering the drying oven 301, avoiding these foreign objects from contaminating the sample and affecting the accuracy of the test results. By setting up an anti-corrosion coating, it can resist the erosion of corrosive gases that may be generated during the drying process and extend the service life of the filter.

[0037] Specifically, such as Figure 5 As shown, a handle 6 is welded to the front of the storage box 308, and the surface of the handle 6 is engraved with anti-slip texture.

[0038] Specifically, such as Figure 3 As shown, the bottom of the pull rod 410 is fitted with a protective sleeve 7, and the surface of the protective sleeve 7 is engraved with anti-slip texture.

[0039] In this embodiment: by setting a handle 6, it is convenient for staff to hold the handle stably when storing and retrieving samples. By setting an anti-slip texture, the friction between the hand and the handle 6 is increased. By setting a protective cover 7, the hand can be protected and the edge of the lever 410 can be prevented from scratching the skin. By setting an anti-slip texture, the friction between the hand and the lever 410 is enhanced, making it easier and more stable for staff to operate the lever 410 to control the raising and lowering of the cover 409.

[0040] Working principle: First, the operator activates the PLC controller 302 to heat the semiconductor heat-conducting plate 307, while the electric fan 304 operates, creating a hot air circulation within the drying chamber 301. The hot air flows upward through the ventilation holes 306, making full contact with the sample in the storage box 308, accelerating the evaporation of moisture from the sample. The humid hot air is then exhausted outside the chamber through the exhaust holes 309. After drying, the sample is removed from the storage box 308 and poured into the support shell 401 of the crushing mechanism 4 through the discharge pipe 403. Next, the operator activates the servo motor 402 via the PLC controller 302. The servo motor 402 drives the rotating rod 404 and the crushing roller 405 to rotate at high speed, grinding the blocky and plate-like samples. The sludge is broken into fine particles. At this time, the cover 409 blocks the discharge hole 406 to prevent uncrushed samples from falling out prematurely. Then, after the sample is crushed, the operator pulls the lever 410 to make the cover 409 slide down the sleeve 407, opening the discharge hole 406. The crushed sample falls into the storage tank 408 under the action of gravity through the sleeve 407 for storage. Then, the operator rotates the storage tank 408 to remove it and transfers the sample inside to the inside of the X-ray fluorescence spectrometer body 2 for detection. The X-ray fluorescence spectrometer body 2 performs qualitative and quantitative analysis on the heavy metals and other elements in the sample to obtain detection data. Finally, after the detection is completed, the operator can take out the sludge sample.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
