Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tires, and in particular to a tread rubber compound mixing and degassing device. Background Technology

[0002] Tire rubber is made from vulcanized silicone as a base material. It is usually made by mixing the proportioned rubber materials in an internal mixer. Therefore, the internal mixer plays an important role in the production and processing of tire rubber.

[0003] Existing rubber compound internal mixing exhaust devices, such as the rubber compound internal mixer for tire rubber processing disclosed in utility model patent application number 201922286277.6, mainly include a fixed frame, an air inlet pipe, a fan, and an exhaust port. A mixing chamber is welded to the upper left side of the fixed frame, and a feed pipe is welded to the top of the mixing chamber. A guide plate is installed inside the feed pipe. The air inlet pipe flange is connected to the left side of the mixing chamber, and a first filter screen is installed inside the air inlet pipe. In use, the prepared rubber compound is put into the feed pipe. Because the feed pipe is equipped with an inclined guide plate, the rubber compound can fall slowly along the guide plate, which can effectively prevent the rubber compound from clogging during the feeding process. Then the rubber compound enters the mixing chamber to start the processing operation.

[0004] However, the exhaust gas from the internal mixer contains a variety of harmful gases and dust. Existing exhaust devices are not effective in treating the exhaust gas, which can easily cause harmful gases to overflow. Moreover, the filters need to be cleaned and replaced frequently, which is very troublesome and affects exhaust efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tire tread rubber compound mixing exhaust device that not only utilizes a filter plate and absorbent liquid to treat harmful gases and dust in the exhaust gas, thus enhancing the exhaust gas treatment effect, but also eliminates the need for frequent disassembly and cleaning of the filter plate, reducing the labor intensity of workers.

[0006] This utility model discloses a tire tread rubber compound internal mixing exhaust device, including a connecting mechanism; it also includes a liquid storage mechanism, a spraying mechanism, a filtering mechanism, an exhaust mechanism, and a driving mechanism. The liquid storage mechanism is installed on the connecting mechanism and stores the absorbent liquid; the spraying mechanism is installed on the liquid storage mechanism and sprays the absorbent liquid; the filtering mechanism is installed on the connecting mechanism and filters waste particles; the exhaust mechanism is installed on the connecting mechanism and blocks moisture in the exhaust gas; the driving mechanism is installed on the exhaust mechanism and drives the exhaust mechanism to draw in air. The connecting mechanism is connected to the exhaust port of the internal mixer. The driving mechanism is started, and the driving mechanism drives the exhaust mechanism to draw in air. The exhaust gas enters the connecting mechanism. The spraying mechanism draws out the absorbent liquid from the liquid storage mechanism and sprays it into the connecting mechanism, working together to absorb harmful gases in the exhaust gas and filter dust. The exhaust gas undergoes secondary absorption and filtration through the filtering mechanism, and the filtered exhaust gas is discharged through the exhaust mechanism.

[0007] Preferably, the connection mechanism includes a treatment box, a connecting pipe, a check valve, a fixed filter plate, a drain pipe, and a drain valve. The bottom of the treatment box is connected to the ground, and the interior of the treatment box has a cavity.

The connecting pipe is connected to the exhaust port of the internal mixer, and the waste gas enters the cavity of the treatment box through the connecting pipe. The check valve prevents the waste gas from flowing back, and the fixed filter plate performs primary filtration of the waste gas. When the absorption capacity of the absorbent is saturated, the operator opens the drain valve, and the absorbent is discharged through the drain pipe.

[0008] Preferably, the liquid storage mechanism includes a liquid storage tank, a barrier net, a liquid filling pipe, a valve, and multiple sets of flushing nozzles. The liquid storage tank is installed on the treatment tank and communicates with the interior of the treatment tank's cavity. The barrier net is installed at the connection between the liquid storage tank and the treatment tank. The liquid filling pipe is installed on the liquid storage tank, the valve is installed on the liquid filling pipe, and the multiple sets of flushing nozzles are all installed on the liquid filling pipe. By setting up the barrier net, dust in the absorbent liquid is prevented from entering one side of the liquid storage tank. When the absorbent liquid's absorption capacity is saturated, the absorbent liquid is discharged through the drain pipe. Then, the valve is opened, and the delivery pump delivers the absorbent liquid into the liquid filling pipe. The absorbent liquid is sprayed out through the flushing nozzles to flush the barrier net. After flushing, the drain valve is closed, and the absorbent liquid continues to be delivered and stored in the liquid storage tank.

[0009] Preferably, the spraying mechanism includes a water pump, a water pumping pipe, filter heads, a water supply network, and multiple sets of spray heads. The water pump is installed on the liquid storage tank, and the inlet of the water pump is connected to the water pumping pipe. The filter heads are internally connected to the water pumping pipe. The water supply network is installed inside the cavity of the treatment tank and located above the fixed filter plate. The water supply network is internally connected to the outlet of the water pump. Multiple sets of spray heads are installed on the water supply network. When the water pump is started, the water pump draws out the absorbent liquid through the water pumping pipe. The filter heads prevent dust from entering the water pump. The absorbent liquid is transported to the multiple sets of spray heads through the water supply network. The multiple sets of spray heads spray out the absorbent liquid, rinsing the fixed filter plate while absorbing harmful gases in the exhaust gas.

[0010] Preferably, the filtration mechanism includes a sliding filter plate, a handle, and a sealing strip. The treatment box has a sliding groove, and the sliding filter plate is slidably installed in the sliding groove of the treatment box. The handle is installed on the sliding filter plate, and the sealing strip is installed on the sliding filter plate. The sliding filter plate performs secondary filtration of the exhaust gas. The sealing strip ensures the sealing effect and the treatment effect of the exhaust gas. During secondary filtration, the amount of dust and harmful gases in the exhaust gas is already reduced, which can reduce the number of times the sliding filter plate needs to be cleaned. When cleaning is required, the operator pulls the handle to remove the sliding filter plate for cleaning.

[0011] Preferably, the exhaust mechanism includes a chimney, two sets of baffles, a protective box, an exhaust fan, and a first pulley. The bottom of the chimney is connected to the top of the treatment box. Both sets of baffles are installed obliquely inside the chimney. The protective box is installed inside the chimney. The exhaust fan is rotatably mounted on the protective box. The first pulley is mounted on the exhaust fan. The drive mechanism drives the first pulley to rotate, and the first pulley drives the exhaust fan to rotate and draw in air. The filtered exhaust gas is discharged through the chimney. During the discharge process, the two sets of baffles block the moisture in the exhaust gas. The protective box reduces the impact of the exhaust gas on the exhaust fan and the first pulley.

[0012] Preferably, the drive mechanism includes a motor, a reducer, a transmission shaft, a second pulley, and a belt.
