[0001] The utility model relates to the technical field of sampling devices, in particular to a closed sampling device for chemical production. Background Art

[0002] After the production of chemical products is completed, it is often necessary to sample the chemical products. Since some chemical products often react with the air in the external environment, a closed sampling device is required during the sampling process. The existing closed sampling device for chemical production (Announcement No.: CN219736932U) has the following disadvantages in use:

[0003] During use, since the storage tank is fixed in a fixed shell, when the storage tank needs to be repaired or replaced, the fixed shell may need to be removed or disassembled, which is inconvenient. It is also inconvenient to disinfect the fixed shell when taking samples, which may result in the bacteria and contaminants in the closed box being unable to be effectively removed, increasing the risk of product contamination. For this reason, this patent proposes a chemical production closed sampling device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the process of sampling chemical products, a chemical production closed sampling device is needed. The chemical production closed sampling device provided by the utility model is specially used for sampling chemical products. In the process of using this equipment for sampling operations, the feed pipe installed on the connecting box 4 needs to be connected to the reactor, so that the product in the reactor can be sent into the connecting box 4, and then sent from the discharge pipe 5 at the bottom of the connecting box 4 into the sampling box 6 for sampling.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a closed sampling device for chemical production, including a sealed box 1 and a sampling box 6, a cylinder 10 is fixed to the inner wall of the bottom end of the sealed box 1, a placement rack 9 is fixed to the output end of the cylinder 10, a clamping mechanism 8 is arranged on the top of the placement rack 9, the clamping mechanism 8 includes a mounting frame 801 fixed to the top of the placement rack 9, a double-headed screw 802 is rotatably connected between the inner walls on both sides of the mounting frame 801, a first motor is fixed to one side of the mounting frame 801, the output end of the first motor passes through the mounting frame 801 and is fixed to the double-headed screw 802, the outer walls of both ends of the double-headed screw 802 are screwed with sliders 804, the mounting frame 801 A limit rod 803 is fixed between the inner walls on both sides, and the limit rod 803 passes through the slider 804. A support frame 805 is fixed at one end of the slider 804. A clamp 806 is fixed on the side where the two support frames 805 are close to each other. The rear inner wall of the sealed box 1 is rotatably connected to a gear 12, and the rear inner wall of the sealed box 1 is slidably connected to a connecting frame 14. An ultraviolet lamp 13 is installed between the connecting frames 14. A rack 11 is fixed to one side of the connecting frame 14, and the rack 11 is meshed with the gear 12. A second motor is fixed to the rear side of the sealed box 1. The second motor and the first motor have a self-locking function, and the output end of the second motor passes through the sealed box 1 and is fixed to the gear 12.

[0021] It should be noted that the double-headed screw 802 is driven to rotate by the first motor. The rotation of the double-headed screw 802 drives the two sliders 804 to move in a direction close to each other, so that the sampling box 6 can be clamped to avoid the sampling box 6 being fixed and unstable during sampling. The double-headed screw 802 is reversed by the first motor, and the two sliders 804 move in a direction away from each other, and the sampling box 6 is no longer clamped, which facilitates the removal and taking of the sampling box 6. In addition, before sampling, the gear 12 can be driven to rotate by the second motor, and the rotation of the gear 12 drives the rack 11 to move, thereby driving the ultraviolet lamp 13 to move to disinfect the sampling box 6.

A pressure detector is installed in the sealed box 1, and a controller is installed on one side of the sealed box 1, and the controller is electrically connected to the first motor, the pressure detector and the second motor.

[0023] It should be noted that by setting the air inlet pipe 3 and the air outlet pipe, nitrogen is introduced into the sealed box 1 through the air inlet pipe 3, and the nitrogen can effectively reduce the presence of oxygen or water vapor, so that the oxygen or water vapor is discharged from the connecting pipe, and before sampling, the discharge pipe 5 needs to be connected to the installation pipe at the top of the sampling box 6, the exhaust pipe 7 is connected to the air outlet pipe at the top of the sampling box 6, the exhaust pipe 7 is externally connected to an air pump, and the air in the sampling box 6 is sucked away by the air pump, and valves are installed on the discharge pipe 5, the installation pipe, the exhaust pipe 7, the air outlet pipe, the air inlet pipe 3 and the connecting pipe.

[0024] Working principle: The first motor and the second motor are started through the controller, and the first motor drives the double-headed screw 802 to rotate. The double-headed screw 802 rotates, driving the two sliders 804 to move, so that the sampling box 6 can be clamped to avoid the sampling box 6 being fixed and unstable during sampling. The second motor drives the gear 12 to rotate, and the gear 12 rotates to drive the rack 11 to move, thereby driving the ultraviolet lamp 13 to move to disinfect the sampling box 6, and then sampling can be carried out.
