Description

Technical Field

[0001] The utility model relates to a sampling structure of a mixer. Background Art

[0002] Existing mixers usually take samples at the downstream of the machine, that is, at the discharge port or the conveying hopper. However, both the discharge port and the conveying hopper are at the back end of the mixing process and the mixing is completed. This structure cannot monitor the mixing situation in the mixing chamber in real time. The existing sampling mechanism opens the sampling port through a cylinder. However, the disadvantage of this is that when sampling materials during the mixing process of the mixer, when the cylinder is used to fully open the sampling valve, the materials will rush out from the discharge port rapidly, and it is easy to spray powder all over the body or everywhere in the workshop. Using a cylinder sometimes cannot close the valve, resulting in powder leakage from the mixer and affecting workshop management. Summary of the Utility Model

[0003] The utility model provides a sampling structure of a mixer, which includes a mixing chamber and a sampling mechanism arranged in the mixing chamber. An installation hole is arranged at the lower part of the mixing chamber, and the sampling mechanism is installed on the installation hole. The sampling mechanism is provided with a sampling cylinder, a sealing gland and a discharge pipe. The discharge pipe is arranged on the side wall of the sampling cylinder and is communicated with the inner cavity of the sampling cylinder. The sealing gland is arranged in the inner cavity and can move along the length direction of the inner cavity to close the sampling port or open the sampling port and the discharge port of the discharge pipe.

[0004] In one or more embodiments, a handwheel is arranged on the sampling mechanism. A driving screw is arranged between the handwheel and the sealing gland, and the driving screw is in tooth connection with the sampling cylinder.

[0005] In one or more embodiments, a fixing nut is arranged on the sampling cylinder. The driving screw is in threaded connection with the fixing nut, and the driving screw moves along the length direction of the sampling cylinder under the drive of the handwheel.

[0006] In one or more embodiments, a sealing ring mounting seat is arranged between the sealing gland and the driving screw, and the sealing ring mounting seat is provided with an O-ring.

[0007] In one or more embodiments, the installation hole is not at the lowest end of the mixing chamber.

[0008] In one or more embodiments, the discharge pipe includes a first section and a second section. The first section is perpendicular to the sampling cylinder, and the second section is located at the rear end of the first section and extends obliquely downward towards the handwheel direction.

[0009] Advantages of the utility model: A sampling mechanism is provided on the side wall of the mixing chamber to facilitate sampling at any time and in real time during mixing. The sampling mechanism drives the driving screw opening and closing hole through the handwheel to sample or close the hole, and can manually control the opening area of the discharge port, facilitating the adjustment of the sampling amount and avoiding the spraying of raw materials and mixed materials.
