Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer capable of spraying trace amounts of volatile oil. Background Art

[0002] During the mixing production process of some materials (such as Chinese medicine granules, pills, etc.), it is necessary to add appropriate amounts of additives according to the process characteristics, such as volatile oil components obtained by extraction and separation.

[0003] The problem with the prior art is that, in view of the volatility of volatile oil, it needs to be added before the total mixing, but the addition method is mostly manual spraying, using a handheld spray pot to spray volatile additives (essential oils, auxiliary materials, etc.) on the materials. In this process, the additives will evaporate quickly in the air, and the lack of spraying cannot achieve a uniform effect, and there are problems such as agglomeration. Moreover, in order to spray the materials in the mixer evenly, it is also necessary to spray the mixer at a large angle, but such cumbersome manual spraying is inefficient. Therefore, it is necessary to improve the design of the mixer so that it can automatically complete the spraying of additives and volatile oils. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a mixer capable of spraying a trace amount of volatile oil.

The mounting cover is sealed and fixedly connected to the spray mounting port. The nozzle seat is arranged on one side of the mixing tank body of the mounting cover. The nozzle seat is provided with a spray outlet on the side facing the mixing tank body. A plurality of oil and gas inlets are arranged on the outer peripheral surface of the nozzle seat. The nozzle is provided with an interface coaxial with the spray outlet on the side facing the mounting cover. One end of the pneumatic control valve is fixedly connected to the mounting cover, and the other end is connected to the interface. The pneumatic control valve is connected to the compression pipeline via an air pipe. The plurality of solid cone nozzles are arranged at each oil and gas inlet of the nozzle seat, and the nozzles face the spray outlet. The plurality of solid cone nozzles comprise an air nozzle and an oil nozzle. The air nozzle is connected to the compression pipeline via an air pipe. The oil cup is arranged on the mounting cover, one end of which is connected to the compression pipeline via an air pipe, and the other end of which is connected to the oil nozzle via an oil pipe.

[0007] By adopting the above technical solution, the air pipe is used to inject air into the oil cup, so that the additive in the oil cup is atomized and sprayed out through the oil pipe and oil nozzle. At the same time, multiple air nozzles are arranged at different angles to output multiple airflows to impact the atomized additive, further disperse the diameter of the atomized particles, and spray them out from the spray outlet.

[0008] The utility model is further configured as follows: the spraying device further comprises a quick connector male head and a quick connector female head which are respectively arranged on the mounting cover body and the oil cup, the quick connector female head is connected to the oil pipe, and the quick connector male head is connected to the oil cup.

[0009] By adopting the above technical solution, the quick connector male head and the quick connector female head are provided so that the installation cover body and the oil cup and the air pipe can be quickly disassembled and assembled.

[0010] A further configuration of the utility model is that a filter screen cover is arranged at the end of the vacuum pipeline inside the mixing tank.

[0011] The above technical solution is adopted to prevent the material from being sucked into the vacuum pipeline during vacuuming.

[0012] Further configuration of the utility model: the spraying device also includes a steering gear and a swing arm member, the swing arm member is arranged at the spraying outlet and cooperates with the steering gear, the steering gear is connected to the mounting cover body, and drives the swing arm member to rotate a certain angle, the swing arm member rotates through the spraying outlet, and the swing arm member is provided with a guide slope surface opposite to the spraying outlet, and the guide slope surface guides the volatile oil sprayed from the spraying outlet to be sprayed sideways.

[0013] A further configuration of the utility model is that the guide slope is provided with a plurality of grooves with different inclination angles, and the steering gear controls the grooves to be aligned with the spray outlet.

[0014] The utility model is further configured as follows: the mixer also includes a PLC controller, a blanking valve for controlling the on-off of a material pipeline, and an air valve for controlling the on-off of a compression pipeline.

After a certain time of feeding, a layer of additives is sprayed, and the action of staggered spraying is repeated layer by layer. The equipment is equipped with an atomizing nozzle (solid cone nozzle) and a flow cup. Through time control, uniform atomization and rated spraying volume are achieved each time within the time period, thereby ensuring the uniform distribution of additives and main materials before mixing, the maximum retention of volatiles, and increasing the maximum mixing effect with additives.

[0016] The spraying angle of the traditional nozzle is limited, usually within a range of 60°, and the inner side of the mixing tank may not be sprayed. Therefore, a servo and a swing arm are set at the spray outlet. The servo signal is used to intermittently drive the swing arm to rotate a certain angle to the bottom of the spray outlet during the spraying process. The mist additive at the spraying point splashes to the side after contacting the guide slope, thereby expanding the spraying range. In addition, multiple grooves with different inclination angles can be set on the guide slope according to the required angle change. The servo can control the rotation angle of the swing arm, so that the operator can rotate the groove required for the working condition to align with the spray outlet, thereby achieving the purpose of spraying the additive fully on the material at more angles.
