Description

Technical Field

[0001] This utility model relates to the field of waste steel drum processing technology, specifically to a protective device for detecting steel drum residues. Background Technology

[0002] Steel drums are widely used in industries such as chemicals, dyes, and pharmaceuticals due to their large capacity and corrosion resistance. After use, steel drums become solid hazardous waste and must be treated before they can be reused or treated into general solid waste before entering the market. There are two common methods for treating steel drums: one is to use solvent cleaning, and the other is to use physical methods to grind the inner and outer walls of the steel drum clean. However, regardless of the method, the waste residue and waste liquid inside the steel drum need to be treated afterward.

[0003] Because the substances contained in steel drums vary, the subsequent processing methods also differ. Workers usually confirm the contents by checking the labels on the drums. However, when the labels on some drums are contaminated, it becomes impossible to confirm the contents of the waste residue or liquid inside. In such cases, a detection device is needed for confirmation. Existing detection devices typically fix the drums to both sides. When drilling or cutting the drums, displacement or even detachment can easily occur, leading to splashing of residue and a significantly increased risk of leakage. Therefore, this solution provides a protective device for detecting residue in steel drums to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a protective device for detecting residues in steel drums is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for detecting residues in steel drums includes a sealed chamber, which comprises a chamber body. A pneumatic assembly is fixedly installed on the outside of the chamber body, and a steel drum workpiece is placed inside the chamber body. An installation groove is provided at the bottom of the chamber body, and a fixing mechanism for fixing the steel drum workpiece is provided inside the installation groove. The fixing mechanism includes a mounting bracket and an explosion-proof servo motor fixedly installed in the installation groove. A threaded rod is rotatably installed on the mounting bracket, and the front end of the threaded rod is fixedly connected to the output shaft of the explosion-proof servo motor. A movable frame is threadedly connected to the threaded rod. Limiting grooves for sliding of the movable frame are provided on both the left and right sides of the installation groove, and a connecting rod is rotatably installed on the upper end of the movable frame. A load-bearing component is rotatably connected to the upper end of the connecting rod.

[0007] Preferably, the support includes a placement platform rotatably connected to the upper end of the connecting rod. Two sets of columns are fixedly installed on the bottom of the cabin at the lower front end of the placement platform. A rotating shaft is rotatably installed at the upper end of each of the two sets of columns, and two sets of symmetrically arranged connecting seats are fixedly installed on the rotating shaft. The lower ends of the two sets of connecting seats are slidably connected to the upper ends of the two sets of columns, and the upper ends of the two sets of connecting seats are fixedly connected to the upper end of the placement platform. Two sets of symmetrically arranged fixing grooves are opened at the rear end of the placement platform, and clamping elements are provided inside the two sets of fixing grooves.

[0008] Preferably, the clamping component includes two sets of clamping plates that slide in two sets of fixed slots respectively. Each set of clamping plates has a hydraulic cylinder fixedly mounted on the placement platform on its front side. The output shaft of the hydraulic cylinder is fixedly connected to the clamping plate respectively. A retaining edge is fixedly connected to the front end of the placement platform. A storage slot for storing the clamping plates is opened at the rear end of the placement platform. A bracket is fixedly connected to the clamping plate. A guide slot for sliding with the placement platform is opened on the placement platform.

[0009] Preferably, a hatch is rotatably installed at the left end of the cabin, and an observation window is fixedly installed on the upper front side of the cabin.

[0010] Preferably, the pneumatic assembly includes a nitrogen generator fixedly installed at the right end of the cabin, with an air inlet fixedly installed at the right end of the nitrogen generator, a filter cover fixedly installed on the air inlet, an air outlet pipe fixedly installed at the top of the nitrogen generator, and a solenoid valve one fixedly installed on the air outlet pipe; the pneumatic assembly also includes a fan fixedly installed at the top of the cabin, with a connecting pipe fixedly installed at the fan's inlet, the lower end of the connecting pipe communicating with the cabin, and a solenoid valve two fixedly installed on the connecting pipe.

[0011] Compared with the prior art, this utility model proposes a protective device for detecting residues in steel drums, which has the following beneficial effects:

[0012] 1. This utility model includes a fixing mechanism for securing steel drums. The steel drum is placed on a placement platform, which is V-shaped with an arc-shaped inner wall to accommodate drums of different sizes. A clamping device is installed on the platform. By driving a hydraulic cylinder within the clamping device, the clamping plate moves the steel drum. Combined with a retaining edge at the front of the platform, this secures the steel drums of different sizes, preventing accidental slippage during subsequent inspections. Simultaneously, a drive for an explosion-proof servo motor rotates a threaded rod, which in turn drives a moving frame. This moving frame then moves a connecting rod, allowing the angle of the platform to be adjusted, thus enabling angle adjustment of the steel drum and facilitating inspection by personnel.

[0013] 2. This utility model is equipped with a pneumatic component. Before testing, the fan and nitrogen generator are started. After the fan and nitrogen generator have been working for a period of time, the sealed chamber is filled with nitrogen, and the oxygen in the sealed chamber is discharged. Then the nitrogen generator and solenoid valve one are turned off, and the fan continues to work for a period of time before the fan and solenoid valve two are turned off. This makes the air pressure in the sealed chamber lower than the outside air pressure, ensuring that any possible leakage is due to the inflow of outside air into the chamber, rather than the escape of pollutants from inside the chamber. At the same time, by injecting inert nitrogen gas into the sealed chamber to replace the oxygen, the environment cannot support combustion, thus avoiding explosion or combustion during subsequent testing.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Reference Figure 1-7 As shown, a protective device for detecting residues in steel drums includes a sealed chamber 1, the sealed chamber 1 includes a chamber body 101, a pneumatic assembly 2 is fixedly installed on the outside of the chamber body 101, a steel drum workpiece 3 is arranged inside the chamber body 101, and an installation groove 102 is opened at the bottom of the chamber body 101. A fixing mechanism 4 for fixing the steel drum workpiece 3 is arranged inside the installation groove 102.

[0028] Furthermore: Workers place the steel drum on the placement platform 409, and then close the hatch 403. Before testing, the air pressure inside the sealed chamber 1 is controlled to be lower than the outside air pressure by the set air pressure component 2, ensuring that any possible leakage is due to outside air flowing into the chamber rather than pollutants escaping from inside the chamber. At the same time, inert nitrogen gas is injected into the sealed chamber 1 to replace the oxygen, making the environment unsuitable for combustion and preventing explosions or combustion during subsequent testing. Then, the steel drum is fixed by the fixing mechanism 4 to prevent the steel drum from accidentally sliding out during subsequent testing. The angle of the steel drum is also adjusted by the fixing mechanism 4 to facilitate subsequent testing by the staff.

[0029] Specifically, in this embodiment, the fixing mechanism 4 includes a mounting bracket 401 and an explosion-proof servo motor 403 fixedly installed in the mounting groove 102. A threaded rod 402 is rotatably mounted on the mounting bracket 401. The front end of the threaded rod 402 is fixedly connected to the output shaft of the explosion-proof servo motor 403. A movable frame 404 is threadedly connected to the threaded rod 402. Limiting grooves 105 for sliding with the movable frame 404 are provided on both the left and right sides of the mounting groove 102. A connecting rod 405 is rotatably mounted on the upper end of the movable frame 404. A bearing member is rotatably connected to the upper end of the connecting rod 405.

[0030] Furthermore: By driving the explosion-proof servo motor 403, the explosion-proof servo motor 403 drives the threaded rod 402 to rotate. The rotation of the threaded rod 402 drives the moving frame 404, which in turn drives the connecting rod 405 to move. The angle of the placement platform 409 can be adjusted through the connecting rod 405, thereby realizing the adjustment of the angle of the steel drum. This facilitates the inspection of the steel drum by the staff. At the same time, the limiting groove 105 is responsible for limiting and guiding the moving frame 405 to ensure the stable movement of the moving frame 405, thereby ensuring the stable adjustment of the angle of the steel drum in the future.

[0031] Specifically, in this embodiment, the support includes a placement platform 409 rotatably connected to the upper end of the connecting rod 405. Two sets of columns 406 are fixedly installed on the bottom of the cabin 101 at the lower front end of the placement platform 409. A rotating shaft 407 is rotatably installed on the upper end of each of the two sets of columns 406. Two sets of symmetrically arranged connecting seats 408 are fixedly installed on the rotating shaft 407. The lower ends of the two sets of connecting seats 408 are slidably connected to the upper ends of the two sets of columns 406 respectively. The upper ends of the two sets of connecting seats 408 are fixedly connected to the upper end of the placement platform 409. Two sets of symmetrically arranged fixing grooves 4010 are opened at the rear end of the placement platform 409, and clamping elements are provided inside the two sets of fixing grooves 4010.

[0032] Furthermore, the placement platform 409 is V-shaped with an arc-shaped inner wall, which allows it to accommodate steel drums of different sizes. With the help of clamping devices, it can fix steel drums of different sizes and prevent them from accidentally slipping out during subsequent inspection. At the same time, driven by the explosion-proof servo motor 403, the placement platform 409 can rotate around the central axis of the rotating shaft 407, thereby adjusting the angle of the steel drum and facilitating the inspection of the steel drum by the staff.

[0033] Specifically, in this embodiment, the clamping component includes two sets of clamping plates 4012 that slide in two sets of fixing slots 4010 respectively. The front side of each set of clamping plates 4012 is provided with a hydraulic cylinder 4014 fixedly installed on the placement platform 409. The output shaft of the hydraulic cylinder 4014 is fixedly connected to the clamping plate 4012 respectively. The front end of the placement platform 409 is fixedly connected with a retaining edge 4011. The rear end of the placement platform 409 is provided with a storage slot 4013 for storing the clamping plate 4012. A bracket 4015 is fixedly connected to the clamping plate 4012. The placement platform 409 is provided with a guide slot 4016 for sliding with the placement platform 409.

[0034] Furthermore, by driving the hydraulic cylinder 4014 in the clamping component, the clamping plate 4012 can move the steel drum. In conjunction with the retaining edge 4011 set at the front end of the placement table 409, and the placement table 409, steel drums of different sizes can be fixed, preventing the steel drums from accidentally slipping out during subsequent inspections.

[0035] Specifically, in this embodiment, a hatch 103 is rotatably installed on the left end of the cabin 101, and an observation window 104 is fixedly installed on the upper front side of the cabin 101.

[0036] Specifically, in this embodiment, the air pressure assembly 2 includes a nitrogen generator 201 fixedly installed at the right end of the cabin 101. An air inlet 202 is fixedly installed at the right end of the nitrogen generator 201, and a filter cover 204 is fixedly installed on the air inlet 202. An air outlet pipe 203 is fixedly installed at the top of the nitrogen generator 201, and a solenoid valve 205 is fixedly installed on the air outlet pipe 203. The air pressure assembly 2 also includes a fan 206 fixedly installed at the top of the cabin 101. A connecting pipe 207 is fixedly installed at the inlet of the fan 206. The lower end of the connecting pipe 207 is connected to the cabin 101, and a solenoid valve 208 is fixedly installed on the connecting pipe 207.

[0037] Further: Before testing, the blower 206 and nitrogen generator 201 are started. The output port of the blower 206 is connected to a duct, which is connected to the subsequent gas purification tower. After the blower 206 and nitrogen generator 201 have been working for a period of time, nitrogen fills the sealed chamber 1 and exhausts the oxygen in the sealed chamber 1. Then, the nitrogen generator 201 and solenoid valve 205 are turned off, and the blower 206 continues to work for a period of time before the blower 206 and solenoid valve 208 are turned off. This makes the air pressure in the sealed chamber 1 lower than the outside air pressure, ensuring that any possible leakage is due to outside air flowing into the chamber, rather than pollutants escaping from inside the chamber. At the same time, the oxygen is replaced by injecting inert nitrogen gas into the sealed chamber, making the environment unsuitable for combustion and preventing explosions or combustion during subsequent testing.

[0038] The working principle of this utility model is as follows: A worker places a steel drum on the placement platform 409, and then closes the hatch 403. Before testing, the blower 206 and nitrogen generator 201 are started. The output port of the blower 206 is connected to a duct, which is connected to the subsequent gas purification tower. After the blower 206 and nitrogen generator 201 have been working for a period of time, nitrogen fills the sealed chamber 1 and exhausts the oxygen in the sealed chamber 1. Then, the nitrogen generator 201 and solenoid valve 205 are closed, and the blower 206 continues to work for a period of time before the blower 206 and solenoid valve 208 are closed. This makes the air pressure in the sealed chamber 1 lower than the outside air pressure, ensuring that any possible leakage is due to outside air flowing into the chamber, rather than pollutants escaping from inside the chamber. At the same time, by injecting inert nitrogen gas into the sealed chamber to replace the oxygen, the environment cannot support combustion, thus avoiding explosions or combustion during subsequent testing.

[0039] Subsequently, by driving the hydraulic cylinder 4014 in the clamping component, the clamping plate 4012 can move the steel drum. In conjunction with the retaining edge 4011 at the front end of the placement platform 409 and the V-shaped placement platform 409, steel drums of different sizes can be fixed to prevent them from accidentally slipping out during subsequent inspections. At the same time, by driving the explosion-proof servo motor 403, the explosion-proof servo motor 403 drives the threaded rod 402 to rotate. The rotation of the threaded rod 402 drives the moving frame 404, which in turn drives the connecting rod 405 to move. The connecting rod 405 can then adjust the angle of the placement platform 409, thereby adjusting the angle of the steel drum and facilitating subsequent inspections of the steel drum by the staff.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 principles of this utility model.
