Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, and in particular to a powder coating mixing system with dust monitoring function. Background Technology

[0002] A powder coating mixing system with dust monitoring capabilities is an integrated system used to sense and collect key parameters in the production environment in real time. Its core function is to continuously track changes in temperature and humidity or suspended dust concentration in the workshop. In the powder coating production process, environmental conditions directly affect the physical properties of raw materials and the quality stability of the final product.

[0003] Powder coating formulations consist of various solid powder raw materials such as resin, curing agent, pigment, filler, and leveling agent. The first step in powder coating production is to physically mix these raw materials in precise proportions to ensure uniform color and performance of the resulting powder. This process is completed in a mixer. During the feeding and mixing process, a large amount of combustible dust cloud is easily generated. Once this dust reaches an explosive concentration, it will cause a severe dust explosion upon encountering any ignition source. Therefore, it is necessary to monitor the dust concentration generated during mixing in real time to avoid excessive dust concentration in the exhaust gas. In view of this, this application proposes a powder coating mixing system with dust monitoring function based on the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a powder coating mixing system with dust monitoring function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A powder coating mixing system with dust monitoring function includes a frame, a mixing tank fixedly installed at the top of the frame, a mixing component installed inside the mixing tank, a dust suction pipe connected to the upper surface of the mixing tank, a filter component connected to one end of the dust suction pipe, an exhaust pipe connected to the end of the filter component, and a dust monitoring component installed on the exhaust pipe. The dust monitoring component includes a probe, a dust leak detector, and a mounting base. The exhaust pipe has a mounting hole. One end of the mounting base passes through the mounting hole and is welded to the exhaust pipe. The mounting base has an internal thread on its inner side. The mounting base is connected to a connecting seat through the internal thread. The dust leak detector is fixedly mounted on one end of the connecting seat. One end of the probe passes through the connecting seat and is fixedly connected to the dust leak detector. The other end of the probe passes through the mounting base and extends into the exhaust pipe.

[0006] Furthermore, the length of the probe extending into the exhaust pipe is between 1 / 3 and 2 / 3 of the exhaust pipe diameter.

[0007] Furthermore, a buzzer alarm is fixedly installed at one end of the dust leak detector, and the signal output terminal of the dust leak detector is electrically connected to the buzzer alarm.

[0008] Furthermore, the mixing assembly includes a reducer fixedly mounted on a frame, a motor fixedly mounted at the input end of the reducer, and a mixing shaft fixedly mounted at the output end of the reducer. One end of the mixing shaft passes through and is rotatably connected to the mixing tank. Several alternating longitudinal and transverse connecting rods are fixedly mounted on the outside of the mixing shaft, and mixing blades are fixedly mounted between the connecting rods. A feed inlet is provided at the top of the mixing tank, and a sealing cover is provided on the feed inlet. A discharge pipe is provided at the bottom of the mixing tank, and a discharge assembly is provided at the discharge pipe.

[0009] Furthermore, the filtration assembly includes a cyclone separator and a cartridge dust collector. The air intake end of the cyclone separator is fixedly connected to the dust collection pipe, and the exhaust end of the cyclone separator is fixedly connected to the cartridge dust collector. The exhaust pipe is fixedly installed at the bottom of the cartridge dust collector.

[0010] Furthermore, the unloading assembly includes a valve plate rotatably installed inside the discharge pipe, a sleeve fixedly installed on the outside of the discharge pipe, a valve stem rotatably installed inside the sleeve, the valve stem being fixedly connected to the valve plate, a wrench fixedly installed at the other end of the valve stem, a pinch plate rotatably installed inside the wrench, a spring fixedly installed between the pinch plate and the wrench, a locking tooth fixedly installed on the outside of the sleeve, and a locking block provided on the pinch plate that matches the tooth groove of the locking tooth.

[0011] Furthermore, the mixing blades are numerous and spirally distributed inside the mixing tank.

[0012] Furthermore, a sealing ring is provided between the connecting seat and the mounting seat, and the sealing ring is made of high-temperature resistant rubber.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a dust monitoring component, allows the filter component to draw in the dust generated during mixing in the mixing tank. After thorough filtration, the dust is discharged through the exhaust pipe. During this process, the dust leak detector continuously monitors the dust concentration in the exhaust pipe and compares this data with the internally preset safety threshold. Under normal circumstances, the dust concentration in the exhaust pipe is extremely low, the dust leak detector reading is stable, and the system operates safely. However, once the filter component malfunctions, a large amount of unfiltered dust-laden gas will instantly penetrate into the exhaust pipe. The probe of the leak detector will immediately sense the sharp increase in dust concentration and display the concentration in real time on the dust leak detector, thus completely eliminating the hidden danger before a large amount of hazardous dust leaks into the workshop environment and reaches an explosive concentration.

[0014] 2. By setting up a filter assembly, the dust-laden gas is immediately drawn out and first enters the cyclone separator for primary purification. Here, the gas rotates at high speed along the tangent, and most of the coarse dust particles are separated and collected by centrifugal force. Subsequently, the gas enters the cartridge dust collector for fine filtration. Fine dust is efficiently blocked on the outer surface of the cartridge, while clean gas enters the clean air chamber and is finally discharged through the exhaust pipe.

[0015] 3. By setting up a discharge assembly, after the mixing process is completed, by squeezing the squeezing plate, the spring is compressed, the locking block separates from the groove on the locking tooth, and the wrench is turned, the wrench drives the valve stem and valve plate to rotate, and the mixed material can be discharged from the gap between the valve plate and the discharge pipe. By releasing the squeezing plate, the locking block engages with another groove on the locking tooth, which facilitates fixing the opening and closing angle of the valve plate.
