Description

Technical Field

[0001] The utility model relates to the technical field of natural asphalt processing, in particular to a melter for natural asphalt processing. Background Art

[0002] Natural asphalt is a natural mineral with adhesive and colloidal properties, usually black or dark brown in color. It is mainly composed of hydrocarbons and is a product of deep rocks in the earth. However, the process of asphalt processing usually requires the use of a melter, which is a device specially used to heat solid substances to liquid state. Natural asphalt is usually solid at room temperature, so it needs to be heated to liquid state through a melter for subsequent processing and application. The function of the melter is to provide enough heat to reduce the viscosity of natural asphalt to a handleable level, making it easier to pump, spray or apply to the desired surface. In addition, heating natural asphalt through a melter can also make it easier to mix and handle to meet a variety of different application requirements.

[0003] For this purpose, a utility model patent with publication number CN213416772U discloses a melter for natural asphalt processing, including a melter, the melter including an upper cover, a shell is provided on the lower surface of the upper cover, two supporting legs are fixedly connected to the lower surface of the shell, a rectangular groove 1 is provided on the upper surface of the shell, and rectangular groove 2 is provided on the front and rear surfaces of the inner wall of the rectangular groove 1. The motor inside the rectangular block 1 drives the connecting rod to rotate, thereby driving the rotating shaft to rotate through the connecting rod and the spring block 1 to rotate the diamond-shaped fan blades. In this way, when the natural asphalt is melted, the diamond-shaped fan blades are driven to rotate. When the heated natural asphalt is softened, it is stirred by the rotation of the diamond-shaped fan blades, which accelerates the melting speed of the natural asphalt. Because the natural asphalt is viscous, the diamond design of the diamond-shaped fan blades enables the natural asphalt to be cut and stirred more quickly, thereby accelerating the melting efficiency and making it more convenient to use.

[0004] However, the stirring method of this patent has certain limitations. The fluidity of natural asphalt is usually poor, and the natural asphalt on the periphery flows slowly to the central heating zone, so the melting time is longer. Utility Model Content

[0005] The purpose of the utility model is to provide a natural asphalt processing melter to address the above-mentioned deficiencies in the prior art, which can effectively make the natural asphalt flow, shorten the melting time and increase the efficiency.

[0006] The technical solution adopted by the utility model is a melter for natural asphalt processing, comprising a tank body, a feed inlet is provided on the top of the tank body, a sealing cover is rotatably installed on one side of the feed inlet through a hinge, a discharge port is provided on the outer wall of one side of the bottom of the tank body, a support frame is fixedly installed on the surface of the tank body, support legs integrally formed with the support frame are provided at the four corners of the support frame, a tank cover is contactingly installed on the top of the tank body, the feed inlet is provided on the tank cover, a support frame is provided above the tank cover, support columns integrally formed with the support frame are provided at the four corners of the support frame, the bottom of the support column is fixedly connected to the tank cover, a stirring device is provided in the support frame, connecting devices are provided on both sides of the tank cover, and a heating wire is laid in the bottom of the tank body.

[0007] Preferably, the stirring device includes a motor, the stator part of the motor is fixedly connected to the support frame, the rotor part of the motor is fixedly connected to a transmission column, the transmission column passes through the tank cover and enters the interior of the tank body, and a spiral blade is fixedly installed on the surface of the transmission column.

[0008] Preferably, the connecting device includes a movable column, which is integrally formed with the tank cover, a fixed column is sleeved on the surface of the movable column, the bottom end of the fixed column is fixedly connected to the support frame, the movable column is slidably installed in the fixed column, a spring is fixedly installed at the bottom of the fixed column, one end of the spring is fixedly connected to the inner wall of the bottom of the fixed column, and the other end is in contact with the movable column, and a handle is fixedly installed on the top of the movable column.

[0009] Preferably, a mounting block is fixedly mounted on the bottom of each supporting leg, and a plurality of mounting holes are formed on the surface of the mounting block.

[0010] Preferably, a sealing ring is fixedly installed at the contact point between the top of the tank body and the tank cover.

[0011] Preferably, a magnetic coupler is fixedly installed at the connection between the motor rotor and the transmission column.

[0012] The utility model is simple and convenient to use. It only needs to feed the natural asphalt to be melted into the tank body through the feed port and then start the motor and the heating wire. The heating wire heats the natural asphalt at the bottom of the tank body to melt it. The rotation of the motor will drive the transmission column to rotate, and then drive the spiral blade to rotate. The rotation of the spiral blade will transport the natural asphalt at the bottom to the top, so that the natural asphalt in the tank body will flow, thereby improving the melting efficiency. When you want to clean the spiral blade and the inside of the tank body, you only need to hold the handle and lift it up to take out the stirring device, which is convenient for cleaning.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the stirring device makes the natural asphalt in the tank body flow, increasing the melting efficiency, and the spiral blades divide the space in the tank body into multiple small areas, which can effectively prevent the natural asphalt from condensing into large blocks. A spring is also provided to assist in lifting the tank cover, reducing the user's physical exertion. BRIEF DESCRIPTION OF THE DRAWINGS
