Description

Technical Field

[0001] The invention relates to the technical field of industrial production, in particular to a biomass melting furnace. Background Art

[0002] Biomass melting furnace is a professional energy-saving and environmentally friendly furnace that uses bioenergy. It uses a crucible to melt and keep warm. It is mainly used to melt or smelt low-melting-point non-ferrous metals and alloys such as aluminum, zinc, lead, tin, and cadmium. It is generally matched with a die-casting machine and can also be used for aluminum liquid insulation, degassing, and refining. It has the characteristics of high efficiency and energy saving, low carbon and environmental protection, and simple operation and maintenance. It is the best product to replace fuel oil, gas, coke furnace, and electric furnace, which can help enterprises reduce energy consumption costs by 30-60%. Nowadays, more and more factories are using biomass melting furnaces. However, due to the large size of biomass melting furnaces used in factories, the feed port is set at a high position, and the feeding work is generally done manually. Workers transport materials to the feed port through tools such as shovels, and feed materials back and forth for a long time, which consumes a lot of physical strength and does not improve work efficiency.

[0003] To this end, a biomass melting furnace is proposed. Summary of the invention

[0004] The object of the present invention is to provide a biomass melting furnace, which can drive a feeding hopper to be lifted by a motor, and control an electric cylinder to move a pushing block upward to push materials out of the feeding hopper.

[0005] To achieve the above object, the present invention provides the following two implementation schemes:

[0006] A biomass melting furnace comprises a base, a support platform is fixedly connected to one side of the top surface of the base, and two pairs of universal wheels are symmetrically fixedly installed on the bottom surface of the base, a foot cup is fixedly installed between each pair of universal wheels, and an anti-slip pad is arranged at the bottom of the foot cup, a lifting unit is arranged between the support platform and the base, the lifting unit comprises a feeding hopper, an observation port is fixedly installed on the side of the feeding hopper, and a protective mechanism is fixedly installed on the side of the feeding hopper and below the discharge port.

[0007] As an embodiment of the present invention, the lifting unit includes a motor, a support rod, a threaded rod, a feeding hopper, multiple electric cylinders and a pushing block. The motor is fixedly mounted on the bottom surface of the support platform, and the output end of the motor is connected to the threaded rod. The lower end of the threaded rod is fixedly connected to the upper surface of the base. The support rod is fixedly connected between the upper surface of the base and the bottom surface of the support platform. The feeding hopper is slidably connected to the support rod, and the feeding hopper is threadedly connected to the threaded rod. A pair of slide grooves are provided on the feeding hopper, and a pushing block is slidably connected between the two pairs of slide grooves. The multiple electric cylinders are fixedly mounted on the inner bottom surface of the feeding hopper and the lower bottom surface of the pushing block.

[0008] As another embodiment of the present invention, the lifting unit includes a motor, a guide rod, two groups of support plates, a motor wheel, a wire rope, a feeding hopper, multiple groups of springs and a pushing block. The motor is fixedly mounted on the support platform, and a guide rod is connected to the bottom of the motor, the lower end of the guide rod is fixedly connected to the upper surface of the base, and the motor output end is fixedly connected to the motor wheel, a wire rope is fixedly connected in the motor wheel groove, and the end of the wire rope is fixedly connected to the top of the pushing block. The two groups of support plates are composed of multiple thin steel plates, the distance between the multiple thin steel plates is 0.2mm-0.3mm, and the upper and lower parts of the support plates are wider and the middle part is narrower. The feeding hopper is slidably connected to the support plates, and a pair of slide grooves are provided inside the feeding hopper, and a pushing block is slidably connected between the two pairs of slide grooves. One end of the multiple groups of springs is fixedly mounted on the upper and lower surfaces of the pushing block, and the other end faces of the multiple groups of springs are fixedly connected to the inside of the feeding hopper.

[0009] Preferably, the protection mechanism comprises a first protection plate and a second protection plate, and the second protection plate is slidably connected inside the first protection plate via a slide rail.

[0010] Preferably, a scale line is provided on one side of the observation port, and the observation port is made of transparent glass.

[0011] Compared with the prior art, the present invention has two beneficial effects:

[0012] 1. By adopting a scheme, the motor drives the threaded rod to rotate, thereby lifting the feeding hopper upward until the second protective plate is aligned with the feed port of the melting furnace, and then by controlling the electric cylinder, the pushing block is pushed to move upward along the slide slot, pushing the material to the discharge port, and then transported to the melting furnace by the first protective plate and the second protective plate. This scheme adopts the method of threaded transmission and electric cylinder pushing to realize the lifting of the feeding hopper, and then feeds the material to the melting furnace. Compared with manual feeding, it is more labor-saving and can realize intermittent feeding to the melting furnace.

[0013] 2. By adopting another scheme, the motor drives the motor wheel, and the motor wheel drives the wire rope to lift the feeding hopper upward to the top of the support plate and clamp it, and then the wire rope drives the push block to move along the slide to push the material to the discharge port, and then transport it to the melting furnace by the first protective plate and the second protective plate. This scheme lifts the feeding hopper by pulling the steel wire to feed the melting furnace. Compared with manual feeding, it is more labor-saving and has enhanced safety performance. It can also control the fuel at any time to realize the transportation to the melting furnaces of different heights, so that the flexibility of the product is enhanced to a certain extent.

The feeding hopper 3 is slidably connected to the support rod 41, and the feeding hopper 3 is threadedly connected to the threaded rod 42. The motor 5 drives the threaded rod 42 to rotate and drives the feeding hopper on the threaded rod 42. The material is moved upward, and a pair of slide grooves 33 are provided on the feeding hopper 3. A pushing block 32 is slidably connected between the two pairs of the slide grooves 33. A plurality of the electric cylinders 37 are fixedly installed on the inner bottom surface of the feeding hopper 3. The pushing block 32 can realize intermittent feeding by controlling the electric cylinder 37. In the working state, the motor 5 drives the threaded rod 42 to rotate, and the threaded rod drives the feeding hopper 3 to be lifted upward along the support rod 41 until the second protective plate 36 is aligned with the feed port of the melting furnace.

[0022] As another specific embodiment of the present invention, the lifting unit includes a motor 5, a guide rod 44, two groups of support plates 43, a motor wheel 6, a wire rope 61, a feeding hopper 3, multiple groups of springs 38 and a pushing block 32.

The lower end of the guide rod 44 is fixedly connected to the upper surface of the base 1, and the output end of the motor 5 is fixedly connected to the motor wheel 6, and the wire rope 61 is fixedly connected in the groove of the motor wheel 6. The end of the wire rope 61 is fixedly connected to the top of the pushing block 32. The two groups of support plates 43 are composed of multiple thin steel plates. The distance between the multiple thin steel plates is 0.2mm-0.3mm, and the upper and lower parts of the support plates 43 are wider and the middle part is narrower.
