Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garbage compression molding, in particular to a molding equipment for garbage derived fuel. BACKGROUND

[0002] Garbage derived fuel is a kind of alternative fuel made by scientific treatment of combustible garbage, which usually includes municipal solid waste, industrial garbage and other types of combustible waste. It has high calorific value and stable combustion performance, and can partially or completely replace traditional fossil fuels such as coal and oil. It is widely used in industrial production, power generation and other fields. First, non-combustible materials (such as metal, glass, stone) in the garbage raw materials are removed by manual or mechanical screening. Then the raw materials are crushed and dried. Finally, the treated raw material particles are put into the molding equipment, which compresses the garbage raw materials into cylindrical particles or block-shaped fuel under high pressure.

[0003] The existing garbage derived fuel molding equipment usually uses a compression roller to press the garbage raw materials into a mold. The mold is usually a strip-shaped groove. As the compression roller continuously presses the raw materials into the mold, the raw materials at the back can push the raw materials at the front out. Although the mold has a certain shaping effect, the pressure applied to the raw materials at the discharge end may not be sufficient, resulting in insufficient tightness of the produced fuel, which is prone to breakage or dropping of the slag. Short fuel rods may have different densities or stacking forms, affecting the contact area of oxygen and fuel and causing uneven combustion. The falling slag particles may also affect the environment. Therefore, we propose a molding equipment for garbage derived fuel. SUMMARY

[0004] The purpose of the present application is to provide a molding equipment for garbage derived fuel to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a molding equipment for garbage derived fuel, comprising a base, a motor fixedly installed on the base, a molding bin fixedly installed on the base, an inlet cylinder fixedly installed on the molding bin, a rotating shaft rotatingly installed in the molding bin and driven to rotate by the motor, a plurality of compression rollers rotatingly installed on the rotating shaft, a plurality of mold grooves arranged in a ring shape on the inner wall of the molding bin, a baffle for providing pressure to the material arranged at the discharge end of each mold groove, two fixed rods slidingly installed on each baffle, one end of each fixed rod fixedly installed on the molding bin, a spring sleeved on each fixed rod, one end of each spring fixedly connected with the corresponding baffle, and the other end fixedly connected with the molding bin, a plurality of timing activated air cylinders fixedly installed on the inlet cylinder, a fixed ring fixedly installed on the output end of the air cylinder, and a cutting ring arranged at the lower end of the fixed ring for cutting the fuel rod.

[0006] A collection hopper for collecting fuel rods is fixedly installed on the base. The collection hopper is arranged in a ring and is fitted around the outer perimeter of the forming chamber. The collection hopper is provided with a discharge port. A baffle plate for sliding the fuel rods toward the discharge port is fixedly installed at the discharge port and is inclined. A conveying ring for conveying fuel rods is rotatably installed inside the collection hopper.

[0007] Preferably, each mold slot has a mold strip at its discharge end, each mold strip is rotatably mounted on the forming chamber, the lower end of each baffle cooperates with the mold strip, magnetic plates are fixedly installed on both sides of each mold strip, and a number of magnetic blocks that are attracted to the magnetic plates are fixedly installed on the outer wall of the forming chamber, with each magnetic block corresponding to a magnetic plate.

[0008] Preferably, a plurality of wedge blocks are fixedly installed on the cutting ring, each wedge block corresponding to a magnetic plate. The upper end of each magnetic plate is provided with an inclined surface that cooperates with the wedge block. A plurality of elastic rods are fixedly installed on the cutting ring, and the upper end of each elastic rod is fixedly connected to a fixed ring.

[0009] Preferably, each of the mold slots is inclined and divided into three stages: a feeding section, a compression section, and a forming section. The size of the feeding section is larger than that of the forming section, and the compression section is funnel-shaped.

[0010] Preferably, the molding chamber is provided with a material collection trough for storing materials, and each mold slot is connected to the material collection trough. Several material feeding plates for allowing materials to enter the material collection trough are fixedly installed on the rotating shaft. The material feeding plates correspond one-to-one with the pressure rollers and are inclined.

[0011] Preferably, a feeding bin for adding adhesive is fixedly installed on the feeding cylinder, a motor is fixedly installed on the feeding bin, a screw shaft for conveying adhesive is fixedly installed at the output end of the motor, a pressure sensing plate for controlling the speed of the motor is fixedly installed inside the collecting hopper, and one end of each fixed rod is fixedly connected to the pressure sensing plate.

[0012] Preferably, a gear ring is fixedly mounted on the rotating shaft, a gear that meshes with the gear ring is rotatably installed in the forming chamber, a gear disc that meshes with the gear is fixedly mounted at the lower end of the conveying ring, and the cross-section of the conveying ring is inclined.

[0013] Preferably, the elastic force of the elastic rod is greater than the magnetic attraction between the magnetic plate and the magnetic block, and greater than the resistance when the cutting ring cuts the fuel rod.

[0014] Preferably, a plurality of ejector rods for pushing fuel rods out of the mold strip are fixedly installed at the lower end of the fixing ring, and the ejector rods correspond one-to-one with the mold strip.

[0015] Preferably, a guide plate for guiding the material to the poking plate is fixedly installed at the top end of the rotating shaft.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1、The motor drives the rotating shaft to rotate, and the compression roller presses the material into the mold groove, so that the material can be extruded when passing through the compression section, thereby improving the compactness of the material. The actual extrusion amount of the material each time is based on the size of the forming section. Since the size of the feeding section is larger than that of the forming section, the amount of material entering the feeding end each time is larger than the amount of material required for extrusion, so that there is enough material during each compression process. As the material is continuously extruded, the baffle will be pushed to slide along the fixed rod against the elastic force of the spring, and the lower end of the baffle will slide in the mold strip, thereby always applying pressure to the discharge end of the material, improving the compactness of the fuel rod, and the mold strip provides support to prevent the fuel rod from breaking or dropping slag.

[0018] 2、The cylinder drives the cutting ring to cut the fuel rod, and the inclined surface of the wedge block cooperates with the inclined surface at the upper end of the magnetic plate. The mold strip is limited by the inclined surface of the wedge block to drive the fuel rod to flip, which facilitates cutting and allows the fuel rod to be separated from the mold strip. After the mold strip is flipped, the wedge block and the cutting ring cannot move downward. At this time, the elastic rod will be compressed, and then the fixed ring will continue to move downward. The material withdrawal rod will push the fuel rod in the mold strip to move downward, preventing the fuel rod from being too sticky to separate from the mold strip.

[0019] 3、The pressure sensing plate detects the extrusion length of the fuel rod. If the pressure sensed by the pressure sensing plate is small, more fuel rods are cut off before reaching the expected length. The motor power is increased to add more adhesive to the material. If the pressure sensed by the pressure sensing plate is large, it means that the number of baffles in contact with the pressure sensing plate is sufficient, and most of the fuel rods have reached the expected length. The motor power remains unchanged. If the pressure sensed by the pressure sensing plate exceeds a certain range, it means that the compactness of the fuel rod is too high, and the porosity inside may be insufficient and affect the burning efficiency. The motor power is reduced to reduce the addition of adhesive. The amount of adhesive added can be adjusted in real time according to the length of the fuel rod output, so that the fuel rod can reach a certain length while ensuring its burning efficiency.

Since the gear ring 25 is engaged with the gear 26, and the gear 26 is engaged with the gear disc 27, the rotating shaft 17 will drive the conveying ring 24 to rotate slowly. After the fuel rod in the mold strip 10 falls, it will fall onto the conveying ring 24. Since the cross section of the conveying ring 24 is inclined, the fuel rod will roll downward under the action of gravity, and finally move to the discharge port 22 along with the conveying of the conveying ring 24.
