Description

Technical Field

[0001] The invention relates to the technical field of drying and sterilizing machinery, and in particular to a horizontal stirring and conveying type electromagnetic drying and sterilizing machine for rural domestic garbage residue. Background Art

[0002] With the improvement of living standards and the acceleration of urbanization, rural domestic waste is increasing, and the problem of "garbage surrounding villages" is becoming increasingly prominent. The management of rural domestic waste is mainly developing in the direction of harmless, reduced and resource-based rural domestic waste. However, at this stage, there are problems such as insufficient drying and incomplete sterilization in the use of rural domestic waste slag to make organic fertilizer.

[0003] Drying is a high-energy unit operation. In order to save energy, researchers have conducted a lot of research work on drying process systems and equipment design, and designed various types of dryers such as bin type, cross flow, counter flow, mixed flow, circulation type and drum type. The working principle of the screw conveyor is that the rotating spiral blades push the material to be transported by the screw conveyor. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the friction resistance of the screw conveyor casing to the material. The spiral blades welded on the rotating shaft of the screw conveyor are of solid type, belt type, paddle type and other types according to the different conveyed materials. The existing solid single spiral has a single function when conveying materials and cannot meet the needs of material mixing, drying and sterilization. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a horizontal stirring and conveying type electromagnetic drying and sterilizing machine for rural domestic garbage residue.

[0005] The object of the present invention is achieved in the following manner:

[0006] A horizontal stirring and conveying electromagnetic drying and sterilizing machine for rural domestic waste residue comprises a reducer connected to a motor, wherein the output end of the reducer is connected to a bidirectional spiral auger, an outer shell is provided on the outside of the bidirectional spiral auger, a feed port is provided on the upper side of the outer shell, a discharge port is provided on the lower side of the outer shell, a barrel is provided between the bidirectional spiral auger and the outer shell, and a sterilizing device is provided on the outer surface of the barrel.

[0007] A controller is also provided on one side of the outer shell, and the controller is respectively connected to the motor and the sterilizing device.

[0008] The controller is a PLC controller.

[0009] The feed port and the discharge port are both connected to the barrel.

[0010] The output end of the reducer is coaxially connected to a bidirectional spiral auger.

[0011] The sterilizing device is an electromagnetic coil, and the electromagnetic coil is wound around the outer surface of the barrel.

[0012] The bidirectional spiral auger includes a transmission shaft, radial blades and axial blades. The radial blades are evenly and spirally distributed on the surface of the transmission shaft. Axial blades are provided on the outer side of the radial blades. The axial blades are fixedly connected to the radial blades. The transmission shaft is fixedly connected to the reducer. Bearing seats are also provided at both ends of the transmission shaft. Shell supports are provided at both ends of the barrel, and bearing seats are provided inside the shell supports.

[0013] The axial twisted blade is spiral-shaped and is used in conjunction with the barrel.

[0014] Compared with the prior art, the present invention adopts two different rotation directions and different pitches to combine the bidirectional spiral auger, one of which is an uninterrupted solid forward spiral structure, i.e. radial spiral blades, and the other is a reverse three-head spiral structure with a larger pitch, i.e. axial spiral blades. The two spiral blades are welded and connected, and the uninterrupted solid forward spiral structure realizes the forward conveying movement of the material, and the reverse three-head spiral structure with a larger pitch realizes the stirring and reflux of the material. When the reverse three-head spiral structure is welded on the forward spiral structure, the feed port and the discharge port are avoided. Electromagnetic heating is used for drying and sterilization, and the structure is simple and convenient. Second, in terms of function, the setting of the reverse three-head spiral structure enables part of the material conveyed forward along the forward spiral structure to reflux. For the mixed material that needs to be stirred, the reflux is conducive to stirring the conveyed material and improving the mixing uniformity of the material; for the material that needs to be dried and sterilized, the reflux increases the movement distance of the material in the working space, and the reverse three-head spiral structure is conducive to lifting the material in the working space, increasing the contact area between the material and the air, and improving the drying and sterilization efficiency of the material. The reverse three-head spiral structure is not set at the feed port, which avoids the problem of material blocking at the feed port. The reverse three-head spiral structure is not set at the discharge port, which is conducive to the output of materials and improves efficiency. The electromagnetic coil is used for heating and drying, which saves energy, reduces environmental pollution, has good sterilization effect and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense. For example, it can be fixedly connected or set, or it can be detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0025] As attached Figures 1 to 5As shown, the present invention provides a horizontal stirring and conveying type electromagnetic drying and sterilizing machine for rural domestic garbage residue, including a reducer 2 connected to a motor 1, wherein the motor 1 is an AC motor, and the "AC motor" is a machine for realizing mutual conversion between mechanical energy and AC electric energy. Due to the great development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have no commutator, so they have a simple structure, are easy to manufacture, are relatively strong, and are easy to make into high-speed, high-voltage, high-current, and large-capacity motors. The output end 3 of the reducer is connected to a bidirectional spiral auger 8, and an outer shell 5 is provided on the outside of the bidirectional spiral auger 8. A feed port 4 is provided on one side above the outer shell 5, and a discharge port 9 is provided on one side below the outer shell 5. A barrel 6 is provided between the bidirectional spiral auger 8 and the outer shell 5. A sterilization device is provided on the outer surface of the barrel 6. The bidirectional spiral auger 8 is combined in two ways with different rotation directions and different pitches, one of which is an uninterrupted solid forward spiral structure, i.e., radial twisted blades 13, and the other is a reverse three-head spiral structure with a larger pitch, i.e., axial twisted blades 14. The two spiral blades are welded and connected, and the uninterrupted solid forward spiral structure realizes the forward conveying movement of the material, and the reverse three-head spiral structure with a larger pitch realizes the stirring and reflux of the material. When the reverse three-head spiral structure is welded on the forward spiral structure, the feed port 4 and the discharge port 9 are avoided. Electromagnetic heating is used for drying and sterilization, and the structure is simple and convenient. Second, in terms of function, the setting of the reverse three-headed helical structure allows part of the material conveyed forward along the forward helical structure to flow back. For mixed materials that need to be stirred, the reflux is conducive to stirring the conveyed materials and improving the uniformity of material mixing; for materials that need to be dried and sterilized, the reflux increases the movement distance of the materials in the working space, and the reverse three-headed helical structure is conducive to lifting the materials in the working space, increasing the contact area between the materials and the air, and improving the drying and sterilization efficiency of the materials. The reverse three-headed helical structure is not set at the feed port 4, which avoids the problem of material blockage at the feed port 4. The reverse three-headed helical structure is not set at the discharge port 9, which is conducive to the output of the materials and improves the efficiency. The electromagnetic coil 7 is used for heating and drying, which saves energy, reduces environmental pollution, has a good sterilization effect, and is highly efficient.

[0026] A controller is also provided on one side of the outer shell 5, and the controller is respectively connected to the motor 1 and the sterilizing device, and has intelligent control and high efficiency.

[0027] The controller is a PLC controller 10, a programmable logic controller (PLC), a digital electronic device with a microprocessor, a digital logic controller for automatic control, which can load control instructions into the memory for storage and execution at any time. The programmable controller is modularly composed of an internal CPU, instruction and data memory, input and output units, power modules, digital simulation and other units.

[0028] Widely used in the field of industrial control. Before the emergence of programmable logic controllers, hundreds of relays and counters were generally used to form an automation system with the same functions. Now, simple programmable logic controller modules have basically replaced these large devices. The system program of the programmable logic controller is generally initialized before leaving the factory, and users can edit the corresponding user program according to their needs to meet different automation production requirements.

[0029] The original programmable logic controller only had the function of circuit logic control, so it was named programmable logic controller. Later, with continuous development, these computer modules with simple functions at the beginning have many functions including logic control, timing control, analog control, multi-machine communication, etc., and the name was changed to programmable controller (Programmable Controller). However, because its abbreviation is also the abbreviation of PC and personal computer (Personal Computer), and due to years of usage habits, people still often use the name of programmable logic controller and still use the abbreviation PLC in terminology.

[0030] The feed port 4 and the discharge port 9 are both connected to the barrel 6. No radial hinge blades 13 are provided at the feed port 4, thereby avoiding the problem of material blockage at the feed port 4. No radial hinge blades 13 are provided at the discharge port 9, thereby facilitating the output of materials and improving efficiency.

[0031] The output end 3 of the reducer is coaxially connected to the bidirectional spiral auger 8. The reducer 2 is a cycloid pinwheel reducer, which is a novel transmission device that applies the planetary transmission principle and adopts cycloid pinwheel meshing. The entire transmission device of the cycloid pinwheel reducer can be divided into three parts: input part, reduction part, and output part. A double eccentric sleeve with an offset of 180° is installed on the input shaft. Two roller bearings called swing arms are installed on the eccentric sleeve to form an H mechanism. The center holes of the two cycloid wheels are the raceways of the swing arm bearings on the eccentric sleeves. The cycloid wheels are meshed with a group of circularly arranged pin teeth on the pin gear to form an internal meshing reduction mechanism with a tooth difference of one tooth. When the input shaft rotates one circle with the eccentric sleeve, due to the characteristics of the tooth profile curve on the cycloid wheel and its restriction by the pin teeth on the pin gear, the movement of the cycloid wheel becomes a planar motion with both revolution and rotation. When the input shaft rotates one circle in the forward direction, the eccentric sleeve also rotates one circle, and the cycloid wheel rotates one tooth in the opposite direction to obtain a reduction in speed. With the help of the W output mechanism, the low-speed rotation of the cycloid wheel is transmitted to the output shaft through the pin shaft, thereby obtaining a lower output speed.

[0032] The sterilization device is an electromagnetic coil 7, which is wound around the outer surface of the barrel 6. The electromagnetic coil 7 and the motor 1 are both connected to an external power supply. The electromagnetic coil 7 is heated and sterilized by high temperature. The specific reference is the Chinese patent document of an electromagnetic heating device with application number CN201820217946.7.

[0033] The electromagnetic coil 7 refers to an inductor coil, which is a device that works on the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire of this electromagnetic field will induce the wires within the range of this electromagnetic field. The effect on the wire that generates the electromagnetic field is called "self-induction", that is, the changing current generated by the wire itself generates a changing magnetic field, and this magnetic field further affects the current in the wire; the effect on other wires within the range of this electromagnetic field is called "mutual induction".

[0034] The electrical characteristics of an inductor are opposite to those of a capacitor, "passing low frequencies and blocking high frequencies". When a high-frequency signal passes through an inductor, it encounters great resistance and is difficult to pass through; while when a low-frequency signal passes through it, the resistance presented is relatively small, that is, the low-frequency signal can pass through it more easily. The resistance of an inductor to direct current is almost zero.

[0035] Resistance, capacitance and inductance all present a certain resistance to the flow of electrical signals in the circuit, and this resistance is called "impedance". The impedance presented by the inductor coil to the current signal uses the self-inductance of the coil. Inductor coils are sometimes referred to as "inductors" or "coils", represented by the letter "L". When winding an inductor coil, the number of turns of the coil is generally called the "turns" of the coil.

[0036] The bidirectional spiral auger 8 includes a transmission shaft 15, radial blades 13 and axial blades 14. The radial blades 13 are evenly and spirally distributed on the surface of the transmission shaft 15. Axial blades 14 are provided on the outer side of the radial blades 13. The axial blades 14 are fixedly connected to the radial blades 13. The transmission shaft 15 is fixedly connected to the reducer 2. Bearing seats 12 are also provided at both ends of the transmission shaft 15. Shell supports 11 are provided at both ends of the barrel 6, and bearing seats 12 are provided in the shell supports 11.

[0037] The axial twisted blade 14 is spiral-shaped and is used in conjunction with the barrel 6 .

[0038] The working process of the present invention is as follows: both ends of the bidirectional spiral auger 8 are installed in the barrel 6 through bearing seats 12, wherein the barrel 6 and the outer shell 5 are provided with a feed port 4 and a discharge port 9, and square shell supports 11 are installed at both ends of the barrel 6 to prevent the rotation of the cylindrical barrel 6. When working, the rural domestic garbage slag bidirectional spiral combined electromagnetic drying and sterilization machine is powered by an AC motor as a power device, and the speed is adjusted by a cycloidal pinwheel reducer to drive the bidirectional spiral auger 8 to rotate, and the electromagnetic coil 7 outside the barrel 6 provides heat for drying and sterilization. The heating time is controlled by a controller to adjust the drying and sterilization temperature; when the bidirectional spiral auger 8 rotates, the material enters the barrel 6 from the feed port 4, and under the action of the bidirectional spiral combined auger, the material moves forward along the radial blades 13, and under the action of the axial blades 14, part of the material refluxes, and the processed material is output from the discharge port 9, thereby realizing the material transportation, stirring, drying and sterilization.

[0039] The bidirectional spiral auger 8 is combined in two ways with different rotation directions and different pitches, one of which is an uninterrupted solid forward spiral structure, i.e., radial spiral blades 13, and the other is a reverse three-head spiral structure with a larger pitch, i.e., axial spiral blades 14. The two spiral blades are welded and connected. The uninterrupted solid forward spiral structure realizes the forward conveying movement of the material, and the reverse three-head spiral structure with a larger pitch realizes the stirring and reflux of the material. When the reverse three-head spiral structure is welded on the forward spiral structure, the feed port 4 and the discharge port 9 are avoided. Electromagnetic heating is used for drying and sterilization, and the structure is simple and convenient. Second, in terms of function, the setting of the reverse three-headed helical structure allows part of the material conveyed forward along the forward helical structure to flow back. For mixed materials that need to be stirred, the reflux is beneficial to stirring the conveyed materials and improving the uniformity of material mixing; for materials that need to be dried and sterilized, the reflux increases the movement distance of the materials in the working space, and the reverse three-headed helical structure is beneficial to lifting the materials in the working space, increasing the contact area between the materials and the air, and improving the drying and sterilization efficiency of the materials; the reverse three-headed helical structure is not set at the feed port 4, which avoids the problem of material blockage at the feed port 4, and the reverse three-headed helical structure is not set at the discharge port 9, which is beneficial to the output of the materials and improves the efficiency; the electromagnetic coil 7 is used for heating and drying, which saves energy, reduces environmental pollution, and has a good sterilization effect and high efficiency.
