Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of particle board raw material drying, in particular to a raw material drying device for particle board production. Background Art
[0002] Particleboard is an engineered wood product made from wood or jute chips pressed and shaped with a synthetic resin or other suitable binder. Particleboard is often confused with oriented strand board (also called particleboard, waffle board or chipboard), which is a different type of fiberboard that uses machined wood chips and is stronger. Particleboard is cheaper, denser, and more uniform than conventional lumber and plywood, making it a good alternative when cost is more important than strength and appearance. Particleboard can be made more attractive by painting or using a wood veneer on visible surfaces. Although it is denser than conventional wood, it is the lightest and weakest type of fiberboard, with the exception of insulation boards. Medium-density fiberboard and hardboard, also called high-density fiberboard, are stronger than particleboard. Different grades of particleboard have different densities, with higher density meaning greater strength and greater resistance to screw fastener failure.
[0003] First of all, in the production process of particleboard, the raw materials need to go through a series of production processes to finally form particleboard, including raw material preparation, drying, adding adhesives and additives, pressing, cooling and cutting. The drying of raw materials is very critical. Its purpose is to ensure that the raw materials have a certain moisture content to improve the bonding force of the adhesive and avoid cracking and stratification during the pressing process. The existing particleboard production raw material drying process is divided into natural drying and hot air drying. After the crushed raw materials are put into the drying equipment or placed in an open area with good sunlight to dry, the water contained in the raw materials is removed and can be put into the next production process. However, when the raw materials are naturally dried, the efficiency of the water contained in the raw materials is low, and a lot of labor and drying time are required. When the raw materials are dried by hot air equipment, the drying efficiency is improved, but when the raw materials are put into the hot air equipment, due to the large amount of raw materials put in, uneven heating may occur at this time, which will affect the subsequent production process, and may break and damage during the compaction process, which will affect the production cost. In this process, the efficiency of raw material drying is reduced and the labor of the staff is increased. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a raw material drying device for particleboard production, which solves the problems of uneven heating and low drying efficiency when drying raw materials for particleboard production.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a raw material drying device for particleboard production, comprising a drying device main body, a loading port is arranged on the outside of the drying device main body, a material discharge port is installed on the outside of the drying device main body, a round rod is fixedly installed inside the drying device main body, blades are sleeved on the outside of the round rod, a round plate is installed on the outside of the round rod, a motor is fixedly installed on the top of the round rod, an air duct is arranged on the outside of the round plate, a hot air blower is installed on the bottom of the air duct, and a bump is installed on the outside of the round rod.
[0006] Preferably, fine holes of uniform size are formed on the outside of the round rod, and the round rod passes through the top of the drying equipment body.
[0007] Preferably, holes are formed on the outside of the blades, and the inside of the blades are hollowed out.
[0008] Preferably, the outer portions of the blades are in contact with the inner wall of the drying device body.
[0009] Preferably, the protrusions are in a trapezoidal shape, and there are six protrusions evenly distributed outside the round rod.
[0010] Preferably, a material receiving box is installed at the bottom of the discharge port, and a fixing plate is installed at the bottom of the hot air blower.
[0011] Preferably, the outer diameter of the blade is equal to the inner diameter of the drying device body.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model allows a worker to pour raw materials from a feed port so that the raw materials enter the interior of a drying device body, and then the worker starts a motor to drive the round rod to rotate, and the round rod drives the blades set on the outside to rotate along the inner wall of the drying device body, and at the same time starts a hot air blower to allow hot air to enter the air duct, and then enter the round plate through the air duct, so that the hot air enters the round rod along the inside of the round plate from the round hole on the outside of the round rod. At this time, the hot air moves downward along the inside of the round rod, and passes through the hollowed-out state of the blade, so that the hot air enters the inside of the blade along the fine holes on the outside of the round rod, and is emitted outwards from the holes on the outside of the blade, so that the hot air enters the interior of the drying device body, and passes through the round plate. The blades are driven to rotate to stir and heat the added particleboard raw materials, so that the moisture in the particleboard raw materials is evaporated through stirring and hot air blowing. Since the added raw materials are stirred by the blades, they may be superimposed on each other, which will affect the heating of the raw materials and cause uneven heating of the raw materials. The rotation of the round rod drives the six externally installed protrusions, and the six protrusions rotate to break up the particleboard raw materials superimposed on the blades, so that they are heated evenly to prevent breakage and damage in the subsequent production process. When the added particleboard raw materials are dried, they are discharged through the discharge port set on the outside of the drying equipment body, thereby improving the efficiency of raw material drying in the process.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figures 1 to 5 As shown, the utility model provides a raw material drying device for particleboard production, including a drying device body 1, a feeding port 2 is arranged on the outside of the drying device body 1, a material discharge port 3 is installed on the outside of the drying device body 1, a round rod 4 is fixedly installed inside the drying device body 1, a blade 7 is sleeved on the outside of the round rod 4, a round plate 6 is installed on the outside of the round rod 4, a motor 5 is fixedly installed on the top of the round rod 4, an air duct 8 is arranged on the outside of the round plate 6, a hot air blower 9 is installed on the bottom of the air duct 8, and a protrusion 10 is installed on the outside of the round rod 4.
[0022] The above scheme is adopted: by pouring the raw materials from the feeding port 2, the raw materials enter the interior of the drying equipment body 1, and the staff starts the motor 5 to drive the round rod 4 to rotate, and the round rod 4 drives the blade 7 to rotate. At the same time, the hot air blower 9 is started to make the hot air enter the air duct 8, and enter the circular plate 6 through the air duct 8, so that the incoming hot air enters the round rod 4 along the inside of the circular plate 6 from the circular hole opened outside the round rod 4. At this time, the incoming hot air moves down along the inside of the round rod 4, and through the hollow state of the inside of the blade 7, the hot air enters the inside of the blade 7 along the fine holes outside the round rod 4, and is emitted outward from the holes outside the blade 7, so that the hot air enters the drying equipment body 1. Inside, the circular plate 6 drives the blades 7 to rotate to stir and heat the added particleboard raw materials, so that the moisture in the particleboard raw materials is evaporated through stirring and hot air blowing. Since the added raw materials are stirred by the blades 7, they may be superimposed on each other at this time, which will affect the heating of the raw materials and cause the problem of uneven heating of the raw materials. The six protrusions 10 installed on the outside are driven by the rotation of the round rod 4. The particleboard raw materials superimposed on the blades 7 are broken up by the rotation of the six protrusions 10. When the added particleboard raw materials are dried, they are discharged through the discharge port 3 set on the outside of the drying equipment body 1, thereby improving the drying efficiency in the process.
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the outside of the round rod 4 is provided with fine holes of uniform size, and the round rod 4 passes through the top of the drying equipment body 1; the outside of the blade 7 is provided with a hole, and the inside of the blade 7 is hollowed out; the outside of the blade 7 is in contact with the inner wall of the drying equipment body 1; the outer diameter of the blade 7 is equal to the inner diameter of the drying equipment body 1.
[0024] The above scheme is adopted: the round rod 4 is driven to rotate by starting the motor 5, and the round rod 4 drives the blade 7 to rotate. The hot air enters through the fine holes opened on the outside of the round rod 4 and the holes on the outside of the blade 7, and moves down along the inside of the round rod 4 to the inside of the blade 7, and blows to the particle board raw material inside the drying equipment body 1 through the holes on the outside of the blade 7, so that the moisture in the particle board raw material is evaporated, thereby improving the efficiency of the subsequent production process. The blade 7 contacts the inner wall of the drying equipment body 1 to prevent the particle board raw material from being contaminated on the inner wall of the drying equipment body 1, causing a waste of raw materials, and at the same time improving the service life of the equipment.
[0025] like Figures 1 to 4 As shown, the protrusion 10 is trapezoidal, and there are six protrusions 10 evenly distributed outside the round rod 4; a receiving box is installed at the bottom of the discharge port 3, and a fixing plate is installed at the bottom of the hot air blower 9.
[0026] The above scheme is adopted: through the six protrusions 10 installed on the outside of the circular plate 6, the particle board raw materials that may be overlapped during the rotation process are broken up, so that the particle board raw materials are heated evenly, and overlapping is prevented, which causes the situation of incomplete drying. When the drying is completed, it is discharged into the receiving box at the bottom through the discharge port 3 and can enter the next production process. In this process, the efficiency of the raw material drying process is improved and the waste of manpower and material resources is reduced.
[0027] The working principle and use process of this utility model:
[0028] First, the staff collects the raw materials for particle board production, and the collected raw materials are crushed into fine raw materials by crushing equipment. At this time, the crushed raw materials are put into the drying processing equipment, and the staff pours the raw materials from the inlet 2 to allow the raw materials to enter the interior of the drying equipment body 1. The staff starts the motor 5, which drives the round rod 4 to rotate, and drives the blades 7 set on the outside to rotate along the inner wall of the drying equipment body 1 through the round rod 4. At the same time, the hot air blower 9 is started to allow the hot air inside the hot air blower 9 to enter the air duct 8, and enter the circular plate 6 through the air duct 8. The hot air is made to enter the round rod 4 from the circular hole opened on the outside of the round rod 4 along the inside of the circular plate 6. At this time, the hot air moves down along the inside of the round rod 4, and the inside of the blade 7 is hollowed out, so that the hot air enters the inside of the blade 7 along the fine holes on the outside of the round rod 4, and is emitted outward from the holes on the outside of the blade 7, so that the hot air Wind enters the interior of the drying equipment body 1, and drives the blades 7 to rotate through the circular plate 6 to stir and heat the added particleboard raw materials, so that the moisture in the particleboard raw materials is evaporated after stirring and blowing with hot air. Since the added raw materials are stirred by the blades 7, they may be superimposed on each other at this time, which will affect the heating of the raw materials and cause the problem of uneven heating of the raw materials. The six protrusions 10 installed on the outside are driven by the rotation of the round rod 4. The particleboard raw materials superimposed on the blades 7 are broken up through the rotation of the six protrusions 10, so that they are heated evenly to prevent breakage and damage in the subsequent production process. When the added particleboard raw materials are dried, they are discharged through the discharge port 3 set outside the drying equipment body 1, and can enter the next production process. In this process, the efficiency of raw material drying is improved, the uneven heating of raw materials is reduced, and the production cost is increased.
