Description

Technical Field

[0001] The invention belongs to the technical field of drying, and in particular relates to a reciprocating circulation dryer based on airflow regulation. Background Art

[0002] The dryers currently on the market use high-temperature gas to dry particles. However, when a large amount of particles are fed at a time or the particles are relatively moist, it is necessary to increase the temperature of the heat source or the power of the circulation pump to increase the drying intensity. This results in high energy consumption and high cost. The high-temperature airflow adjustment method adopted in this solution has higher control accuracy and is more convenient for temperature adjustment than relying solely on the airflow valve. It can also adopt intermittent high-intensity high-temperature airflow impact to improve drying efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a reciprocating circulation dryer based on airflow regulation, comprising a drying chamber and a reciprocating drying mechanism, wherein the drying chamber comprises a hopper, a motor, a stirring blade and a threaded plug, and the reciprocating drying mechanism comprises a ring pipe, a connecting block, a hydraulic chamber, a hydraulic plate, a hydraulic rod and an airflow regulating part; the airflow regulating part comprises an regulating chamber, the hopper is fixedly mounted on the bottom of the inner wall of the drying chamber, and a thread is provided on the bottom and is threadedly connected to the threaded plug, the motor is fixedly mounted in the drying chamber, and the output end is fixed to the stirring blade, the stirring The leaves are located in the hopper, and a number of air holes are provided on the surface of the hopper. The hydraulic chamber is fixedly installed below the drying chamber, and the hydraulic plate is slidably connected to the inner wall of the hydraulic chamber. The ring pipe is fixedly installed on the connecting block, and the bottom of the connecting block is fixedly connected to the hydraulic plate through a hydraulic rod. A number of air pipes are provided around the inner side of the ring pipe. The regulating chamber is fixedly installed above the drying chamber, and the top is connected to the external circulation pump pipeline, and the bottom is connected to the ring pipe with a hose. A circulation pipe is connected between one side of the drying chamber and the external circulation pump, and the external circulation pump is connected to the external hot air pipeline.

[0005] The present invention further states that the bottom of the hydraulic chamber is connected to an external liquid pump pipeline, and the annular pipe is located outside the hopper.

[0006] The present invention further describes that an airflow block is provided on the inner wall of the regulating chamber, an airflow hole is provided in the middle of the airflow block, and the edge is conical, a threaded hole is opened above the regulating chamber, and a screw is threadedly connected to the threaded hole, and a sphere is fixedly connected to the bottom end of the screw, and the sphere is located in the middle position above the airflow block.

[0007] The present invention further describes that a thread groove is provided below the inner wall of the regulating chamber, and a disc is threadedly connected in the thread groove, two air holes are provided on the surface of the disc, a spring is provided between the disc and the airflow block, and the airflow block is slidably connected in the regulating chamber.

[0008] The present invention further describes that a rotating shaft is fixed above the disc, a through hole is provided between the screw and the sphere, and the rotating shaft is rotatably connected in the through hole.

[0009] The present invention further describes that the sphere includes an upper hemisphere and a lower hemisphere, the bottom of the upper hemisphere is magnetically connected to a limiting rod, a circular hole is provided on the left side of the lower hemisphere, and the limiting rod is inserted into the circular hole to connect the upper hemisphere and the lower hemisphere; the upper hemisphere and the bottom end of the screw are fixed to each other, and a circular hole is provided at the bottom, and a cylinder is provided above the lower hemisphere, and the cylinder is inserted into the circular hole.

[0010] The present invention further describes that grooves are provided on the left and right sides of the cylinder, and protrusions are provided on the front and back sides of the circular hole; after the bottom surface of the lower hemisphere is tightly fitted with the upper surface of the airflow block, the screw is rotated and the protrusion is inserted into the groove, that is, the lower hemisphere moves upward.

[0011] The present invention further illustrates that a limiting block is provided above the airflow block, and the limiting block is fixed to the inner wall of the regulating cavity.

[0012] Compared with the prior art, the present invention has the following beneficial effects: the present invention uses a circulating high-temperature airflow to quickly dry the particles, greatly improving the drying efficiency, and the high-temperature airflow is ejected through the air pipes around the ring tube, which makes the drying more complete and comprehensive, greatly increasing the drying efficiency, and the reciprocating air jet can fully dry a large number of particles, further improving the drying efficiency;

[0013] When the particles are relatively moist and the single input amount is large, the operator can rotate the screw to reduce the gap between the conical surface of the airflow block and the sphere, increase the flow rate of the airflow, and thus increase the force when it is ejected from the annular tube. This allows for high-intensity centralized high-temperature drying of large quantities of moist particles, which increases the intensity of drying and greatly enhances the efficiency. On the contrary, when the particles are relatively dry, the gap between the sphere and the airflow block increases, and the gas flow rate slows down, thus avoiding damage to the particles caused by high intensity and high temperature, and improving the quality of the particles.

[0014] By setting a spring, when the air pressure above the airflow block is greater than the elastic force of the spring, the airflow block is pressed to slide downward along the inner wall of the regulating chamber, so that a gap is created between the sphere and the airflow block again, and the pressure is relieved. After the pressure is relieved, the force of the spring is greater than the force of the air pressure above, so that the sphere and the airflow block fit together again. The impact force of the airflow during pressure relief is large, and the intensity when it is ejected from the air pipe is further improved. The drying intensity is also relatively improved, and it plays the role of an intermittent jet, which can avoid damage to the particles caused by continuous high-temperature jetting and protect the quality of the particles to the greatest extent.

DETAILED DESCRIPTION

[0027] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0028] See also Figures 1-10 The present invention provides a technical solution: a reciprocating circulation dryer based on airflow regulation, comprising a drying chamber 1 and a reciprocating drying mechanism, wherein the drying chamber 1 comprises a hopper 11, a motor, a stirring blade 12, and a threaded plug 13, and the reciprocating drying mechanism comprises a ring pipe 21, a connecting block 22, a hydraulic chamber 23, a hydraulic plate 231, a hydraulic rod 232, and an airflow regulation part;

[0029] The air flow regulating part includes a regulating chamber 31, the hopper 11 is fixedly mounted on the bottom of the inner wall of the drying chamber 1, and a thread is provided on the bottom and is threadedly connected to the threaded plug 13, the motor is fixedly mounted in the drying chamber 1, and the output end is fixed to the stirring blade 12, the stirring blade 12 is located in the hopper 11, and a plurality of air holes are provided on the surface of the hopper 11, the hydraulic chamber 23 is fixedly mounted on the bottom of the drying chamber 1, and the hydraulic plate 231 is slidably connected to the inner wall of the hydraulic chamber 23, the annular tube 21 is fixedly mounted on the connecting block 22, and the bottom of the connecting block 22 is fixedly connected to the hydraulic plate 231 through a hydraulic rod 232, and a plurality of air pipes are provided around the inner side of the annular tube 21, the regulating chamber 31 is fixedly mounted above the drying chamber 1, and the top is connected to the external circulation pump pipeline, and the bottom and the annular tube 21 are connected by a hose, a circulation pipe is connected between one side of the drying chamber 1 and the external circulation pump, and the external circulation pump is connected to the external hot air pipeline;

[0030] The operator puts the particles into the drying chamber 1 and they fall into the hopper 11. Then the motor starts to drive the stirring blade 12 to rotate and stir the particles. At the same time, the external circulation pump extracts high-temperature gas and injects it into the adjustment chamber 31 through the pipeline. Then it enters the annular tube 21 through the hose and is finally ejected from the air pipe. The high-temperature airflow enters the hopper 11 through the air holes of the hopper 11 to dry the stirred particles at high temperature. After that, the high-temperature airflow is extracted by the external circulation pump through the circulation pipe and circulated into the drying chamber 1 again. The circulating high-temperature airflow quickly dries the particles, greatly improving the drying efficiency. The high-temperature airflow is ejected through the air pipes around the annular tube 21, making the drying more sufficient and comprehensive, and greatly increasing the drying efficiency.

[0031] The bottom of the hydraulic chamber 23 is connected to the external liquid pump pipeline, and the ring pipe 21 is located outside the hopper 11;

[0032] When the annular tube 21 ejects high-temperature gas through the air pipe, the external liquid pump starts to inject liquid into the hydraulic chamber 23. The hydraulic pressure pushes the hydraulic plate 231 to slide upward along the inner wall of the hydraulic chamber 23. The hydraulic plate 231 drives the connecting block 22 to move upward through the hydraulic rod 232. Then the liquid pump extracts liquid again, causing the connecting block 22 to return downward, thereby driving the annular tube 21 to move up and down. The annular tube 21 ejects high-temperature airflow from bottom to top and then from top to bottom, performing reciprocating jetting, thereby being able to fully dry large quantities of particles and further improving the drying efficiency.

[0033] An airflow block 32 is provided on the inner wall of the regulating chamber 31. An airflow hole is provided in the middle of the airflow block 32 with a tapered edge. A threaded hole is provided above the regulating chamber 31, and a screw 39 is threadedly connected to the threaded hole. A sphere is fixedly connected to the bottom end of the screw 39, and the sphere is located in the middle position above the airflow block 32.

[0034] After the external circulation pump injects high-temperature gas into the regulating chamber 31, the airflow enters the bottom through the airflow hole in the middle of the airflow block 32, and then enters the ring pipe 21 through the hose;

[0035] Example 1:

[0036] like Figure 5 As shown, the particles are relatively wet and the single input amount is large. At this time, the operator can rotate the screw 39 to make it move downward while rotating through the threaded hole, thereby driving the sphere to move downward, and the gap between the conical surface of the airflow block 32 and the sphere is reduced. The flow rate of the airflow increases, and the force of the airflow when it is ejected from the annular tube 21 is enhanced, and a large number of wet particles are dried with high intensity and high temperature. The intensity of the drying is improved and the efficiency is greatly enhanced. On the contrary, when the particles are relatively dry, only low intensity drying is required, and the screw 39 is rotated in the opposite direction. At this time, the gap between the sphere and the airflow block 32 is increased, and the gas flow rate is slowed down, thereby avoiding damage to the particles caused by high intensity and high temperature, and improving the quality of the particles.

[0037] A threaded groove is provided at the lower portion of the inner wall of the regulating chamber 31, and a disc 33 is threadedly connected to the threaded groove. Two air holes are provided on the surface of the disc 33. A spring 34 is provided between the disc 33 and the air flow block 32. The air flow block 32 is slidably connected to the regulating chamber 31.

[0038] Example 2:

[0039] like Figure 6As shown, a large number of particles are put in at a time, the particles are accumulated, and the gaps between the particles are small. At this time, the operator can rotate the screw 39 to make the sphere and the airflow block 32 fit together, and there is no gap between the sphere and the airflow block 32. The external circulation pump continuously injects hot air into the regulating chamber 31. When the air pressure above the airflow block 32 is greater than the elastic force of the spring 34, the airflow block 32 is pressed to slide downward along the inner wall of the regulating chamber 31, so that a gap is generated between the sphere and the airflow block 32 again, and the pressure is relieved. After the pressure is relieved, the force of the spring 34 is greater than the air pressure force above, so that the sphere and the airflow block 32 fit together again. The impact force of the airflow during pressure relief is large, and the intensity when ejected from the air pipe is further improved. The drying intensity is also relatively improved, and it plays the role of an intermittent jet, which can avoid damage to the particles caused by continuous high-temperature jetting and protect the quality of the particles to the greatest extent.

[0040] A rotating shaft 35 is fixed above the disc 33. A through hole is provided between the screw 39 and the sphere, and the rotating shaft 35 is rotatably connected to the through hole.

[0041] Example 3:

[0042] like Figure 7 As shown, when the amount of particles input is moderate, the motor stops running, thereby protecting the roundness of the particles. At the same time, the operator rotates the shaft 35, and the shaft 35 drives the disc 33 to rotate. The disc 33 moves upward while rotating through the threaded groove, and the extrusion force on the spring 34 increases. Therefore, only when the gas above the airflow block 32 increases further will it be greater than the force of the spring 34, thereby pressing the airflow block 32 downward, and the intensity of the gas ejection is further enhanced, which can blow the particles in the hopper 11 to roll, thereby ensuring the roundness of the particles and drying the particles with the fastest efficiency. In addition, the frequency of intermittent air jets is reduced, which can avoid multiple high-intensity hot air jets that damage the particles, thereby protecting the quality of the particles.

[0043] The sphere includes an upper hemisphere 36 and a lower hemisphere 37. The bottom of the upper hemisphere 36 is magnetically connected to a limit rod. A circular hole is provided on the left side of the lower hemisphere 37, and the limit rod is inserted into the circular hole to connect the upper hemisphere 36 and the lower hemisphere 37.

[0044] The upper hemisphere 36 and the bottom end of the screw rod 39 are fixed to each other, and a circular hole 361 is provided at the bottom. A cylinder 371 is provided above the lower hemisphere 37 and the cylinder 371 is inserted into the circular hole 361 .

[0045] The left and right sides of the cylinder 371 are provided with grooves, and the front and rear sides of the circular hole 361 are provided with bumps;

[0046] After the bottom surface of the lower hemisphere 37 is tightly fitted with the upper surface of the airflow block 32, the screw 39 is rotated and the protrusion is inserted into the groove, that is, the lower hemisphere 37 moves upward.

[0047] A limit block 38 is provided above the air flow block 32, and the limit block 38 is fixed to the inner wall of the regulating cavity 31;

[0048] The upper hemisphere 36 is magnetically attracted to the lower hemisphere 37, thereby connecting the lower hemisphere 37 and the upper hemisphere 36, preventing the lower hemisphere 37 from being separated from the upper hemisphere 36, and the upper hemisphere 36 can rotate smoothly through the magnetic attraction;

[0049] Example 4:

[0050] When the amount of particles added at a time increases compared to that in Example 3, and the particles are relatively moist, in order to avoid incomplete drying, the disc 33 presses the spring 34 upward, so that the force between the air flow block 32 and the lower hemisphere 37 is greater. At this time, the screw 39 is rotated again, and the lower hemisphere 37 is kept stationary by the force of the air flow block 32. At the same time, the screw 39 drives the upper hemisphere 36 to rotate, so that the protrusion of the circular hole 361 is aligned with the groove of the cylinder 371, so that the protrusion is inserted into the groove, and the lower hemisphere 37 loses the support of the upper hemisphere 36. At this time, in Example 2, the air pressure above the air flow block 32 is greater than the force of the spring 34, which can quickly press the air flow block 32 downward, thereby relieving pressure. At this time, in order to ensure the duration of pressure relief, the lower hemisphere 37 is affected by gravity and slides along the protrusion through the groove, thereby slowly moving downward until it fits with the air flow block 32 again. In this process, the circulation time of the air flow is guaranteed, and more and stronger high-temperature air flow can be circulated, thereby drying the relatively moist particles more quickly.

[0051] The airflow regulator has a simple structure and low manufacturing cost, and compared with the airflow valve, it is more efficient in controlling the airflow and has better use effect.
