Description

Technical Field

[0001] The present invention relates to the technical field of drying and energy-saving equipment, in particular to a modified particle processing and drying device. Background Art

[0002] Modified particles refer to PVC, also known as polyvinyl chloride, as a polymer material. Generally, they cannot be used alone and must be modified to change their properties. During the processing of modified particles, they need to be cleaned and dried. Drying modified particles mainly involves evenly drying the moisture in the modified particles, thereby achieving a drying effect and facilitating their use in subsequent production processes. Technical inspiration for drying modified particles;

[0003] The research on drying modified particles found the following problems:

[0004] When the modified particle drying device dries the modified particles, it dries the modified particles through a hot air flow. The hot air flow is ejected through the nozzle to vibrate the carrier plate, and the carrier plate rotates with the driving member. However, the modified particles are small in size. While the modified particles rotate and vibrate with the carrier plate, the modified particles cannot remain on the surface of the carrier plate. As a result, the modified particles are directly discharged without being completely dried, thus failing to achieve the purpose of drying.

[0005] At present, CN112033117A in the prior art discloses an energy-saving drying device for particle processing, which discloses a modified particle drying device. The invention uses a driving member to drive the rotating vertical rod shaft to rotate, and the blower blows the external airflow into the drying chamber from multiple locations to disperse the airflow, which can increase the contact and fluidity of the internal particles and improve the drying effect. The electric heating plate generates heat when it is energized and rotates the vertical rod shaft. The electric heating plate can fully heat and dry the particles. When the hollow paddle plate rotates, the airflow ejected from the nozzle through the nozzle can cause the hollow paddle plate to vibrate up and down. The airflow blows towards the hollow paddle plate, causing it to vibrate and cooperate with its rotation to flip the particles, and the electric heating plate is used for heating.

[0006] The present invention can mainly solve the problem that the modified particles cannot remain on the surface of the carrier plate during the process of following the rotation and vibration of the carrier plate, resulting in the modified particles being unable to achieve a drying effect. Summary of the Invention

[0010] Furthermore, the electric heating plates are respectively embedded in the surface and side surfaces of the spiral blades, and the electric heating plates are arranged in a mesh shape, and the size of the mesh inside the mesh is smaller than the size of the modified particles.

[0011] Furthermore, the limit block is set in the groove inside the spiral blade through the rotating shaft, the size of the limit block matches the size of the hollow inside the spiral blade, and the end of the return spring away from the limit block is embedded in the interior of the rotating shaft.

[0012] Furthermore, the auxiliary components include a feed bin, a guide main board, a slider, a slide rail, an auxiliary block, a guide sub-plate, a reset spring and a clamping block. The guide main board is provided at the bottom of the feed bin, a slider is installed on one side of the guide main board, a slide rail is provided on the outer side of the slider, a guide sub-plate is installed on the inner wall of the guide main board, a reset spring is provided inside the guide main board, a clamping block is installed at one end of the reset spring, a slide rail is provided inside the feed bin, and an auxiliary block is installed at the inner center of the feed bin.

[0013] Furthermore, the bottom of the feed bin is comma-shaped, and its bottom end is open. Slide rails are installed on the front and rear sides of the inner wall of the opening. The slide rails and the slider are matched. A slot is provided on the outer side of the slide rail, and one side of the slot is arc-shaped.

[0014] Furthermore, the guide main board is fitted with the opening on one side of the top of the spiral blade, and the side of the guide main board fitted with the spiral blade is open. The opening is arc-shaped and matches the curvature of the side of the top of the spiral blade.

[0018] Beneficial effects:

[0019] 1. The modified particles enter the guide main board through the comma end at the bottom of the feed bin and then flow into the opening at the top of the spiral blade. The modified particles enter the interior of the spiral blade through the through hole on one side of the top of the spiral blade. As the modified particles pass through the limit block inside the spiral blade, they are limited by the elasticity of the internal return spring, thereby preventing the modified particles from flowing out directly during the preparation work;

[0020] 2. The heat exchange air duct heats the external airflow and then discharges it into the drying chamber of the drying box through the baffle plate. The hot airflow has high energy, the distance between gas molecules is large, and the gas with low density is light, so the hot airflow moves upward after entering the drying chamber of the drying box. At the same time, the electric heating plate starts to heat the modified particles entering the spiral blades. The hot airflow is arranged in a mesh shape through the electric heating plate, and then the hot airflow moves upward and continuously heats and dries the modified particles inside the spiral blades until it moves to the top of the drying box and enters the air guide chamber again through the gap between the baffle plate and the drying box;

[0021] 3. The servo motor drives the connecting shaft to rotate the spiral blade. The centrifugal force is generated during the rotation of the spiral blade. The centrifugal force acts on the limit block and the modified particles instantly. The modified particles, under the action of the centrifugal force, push the limit block to one side, and then continue to rotate and move downward along the spiral shape of the spiral blade. The modified particles generate power and centrifugal force during the rotation process, and when they come into contact with the electric heating plate, they collide and flip, thereby achieving the effect of uniform heating and drying of the modified particles.

[0022] 4. The spiral blades collide with the guide main plate several times during the rotation process. The guide main plate increases the thrust of the spiral blades through the curved side, and then the guide main plate moves inside the slide rail through the slider into the bottom of the feed bin. The return spring is continuously squeezed by the push block of the feed bin, so that after the guide main plate enters the bottom of the feed bin, the squeeze on the return spring is canceled. The return spring elastically pushes the block into the slot on the outer side of the slide rail, thereby preventing the guide main plate from affecting the rotation of the spiral blades.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] As attached Figure 1 To the attached Figure 9 As shown:

[0036] Example 1

[0037] A modified particle processing and drying device includes a drying box 1, a blower 3 installed on one side of the drying box 1, a connecting pipe 301 installed on the output end of the blower 3, a secondary pipe 302 installed on the outer side of the connecting pipe 301, a heat exchange air guide pipe 303 installed on the end of the secondary pipe 302 away from the connecting pipe 301, and a baffle 101 provided on one end of the heat exchange air guide pipe 303. A collection box 4 is installed on one side of the bottom of the drying box 1, and a rotating assembly for drying is installed on one side of the collection box 4. The rotating assembly includes a motor compartment 5, a servo motor 501, a connecting shaft 502, a spiral blade 503, an electric heating plate 504, a limit block 505, a rotating shaft 506, and a return spring 507.

[0038] A servo motor 501 is provided inside the motor compartment 5, a connecting shaft 502 is installed at the output end of the servo motor 501, a spiral blade 503 is installed on the outer side of the connecting shaft 502, a heating plate 504 is provided on the surface of the spiral blade 503, a limit block 505 is provided inside the spiral blade 503, a return spring 507 is provided inside the limit block 505, and a rotating shaft 506 is provided on the outer side of the return spring 507;

[0039] The bottom of the drying box 1 is provided with a disc-shaped through hole, and the blocking plate 101 is located inside the drying box 1 and is not connected to the top of the drying box 1;

[0040] The spiral blade 503 is hollow inside, with a through hole formed on one side of the top of the spiral blade 503. An auxiliary component for limiting the position of the modified particles is fitted on one side of the through hole. One end of the bottom of the spiral blade 503 is open, and a groove is formed inside the spiral blade 503.

[0041] The electric heating plate 504 is respectively embedded in the surface and side of the spiral blade 503, and the electric heating plate 504 is arranged in a mesh shape, and the size of the mesh inside the mesh is smaller than the size of the modified particles;

[0042] A stopper 505 is disposed in a groove inside the spiral blade 503 via a rotating shaft 506. The size of the stopper 505 matches the size of the hollow portion inside the spiral blade 503. An end of a return spring 507 away from the stopper 505 is embedded in the interior of the rotating shaft 506.

[0043] The modified particles enter the interior of the spiral blade 503 through the through hole on one side of the top thereof. As the modified particles pass through the limit block 505 inside the spiral blade 503, they are limited by the elasticity of the internal return spring 507, thereby preventing the modified particles from directly flowing out during the preparation work. The electric heating plate 504 and the blower 3 are started, and the blower 3 introduces the external airflow into the auxiliary pipe 302 through the connecting pipe 301, and then introduces the airflow into the heat exchange air duct 303 through the auxiliary pipe 302. The heat exchange air duct 303 heats the external airflow and then discharges it into the drying chamber of the drying box 1 through the baffle plate 101. The hot airflow has high energy, the distance between gas molecules is large, and the gas with low density is light, so that the hot airflow moves upward after entering the drying chamber of the drying box 1. At the same time, the electric heating plate 504 is started to heat the modified particles entering the interior of the spiral blade 503. , the hot air flow is arranged in a mesh shape through the electric heating plate 504, and then the hot air flow moves upward to continuously heat and dry the modified particles inside the spiral blade 503, until it moves to the top of the drying box 1 and enters the air guide chamber again through the gap between the baffle plate 101 and the drying box 1. During this process, the servo motor 501 drives the connecting shaft 502 to rotate the spiral blade 503. The spiral blade 503 generates centrifugal force during its rotation, and the centrifugal force instantly acts on the limit block 505 and the modified particles. The modified particles acted upon by the centrifugal force push the limit block 505 to move to one side, and then continue to rotate and move downward along the spiral shape of the spiral blade 503. The modified particles generate power and centrifugal force during the rotation process, and collide and flip when they come into contact with the electric heating plate 504, thereby achieving the effect of uniform heating and drying of the modified particles;

[0044] Example 2

[0045] The difference between this embodiment and embodiment 1 is that the auxiliary components include a feed bin 2, a guide main plate 201, a slider 202, a slide rail 203, an auxiliary block 204, a guide sub-plate 205, a return spring 206 and a clamping block 207. The guide main plate 201 is provided at the bottom of the feed bin 2, a slider 202 is installed on one side of the guide main plate 201, a slide rail 203 is provided on the outer side of the slider 202, a guide sub-plate 205 is installed on the inner wall of the guide main plate 201, a return spring 206 is provided inside the guide main plate 201, a clamping block 207 is installed at one end of the return spring 206, a slide rail 203 is provided inside the feed bin 2, and an auxiliary block 204 is installed at the inner center of the feed bin 2.

[0046] Among them, the feed bin 2, the bottom of the feed bin 2 is set in a comma shape, and its bottom end is set in an open shape. The front and rear sides of the inner wall of the opening are equipped with slide rails 203. The slide rails 203 are matched with the slider 202. The outer side of the slide rail 203 is provided with a slot, and one side of the slot is set in an arc shape;

[0047] The guide plate 201 is configured to fit in with the opening on one side of the top of the spiral blade 503. The guide plate 201 is configured to fit in with the opening on the side of the spiral blade 503. The opening is arc-shaped and matches the curvature of the top side of the spiral blade 503.

[0048] The inner corners of the guide main plate 201 are all arranged in a barb shape, and the upper and lower surfaces of the guide main plate 201 are provided with a slide groove. The guide main plate 201 is embedded in one side of the feed bin 2 and is arranged in an open manner.

[0049] Auxiliary blocks 204 are installed on the left and right sides of the inner wall of the bottom opening of the feed bin 2, and the auxiliary blocks 204 are arranged in a triangular shape with the width gradually widening from bottom to top. The size of the auxiliary blocks 204 matches the size of the grooves on the upper and lower surfaces of the guide main plate 201;

[0050] The guide plate 205 is embedded in the inner corner hook of the guide main plate 201. The two are slidably connected.

[0052] The modified particles enter the guide main plate 201 through one end of the comma at the bottom of the feed bin 2 and then flow into the top opening of the spiral blade 503. After the material is discharged, the spiral blade 503 rotates with the connecting shaft 502, and one side of the guide main plate 201 is in an arc shape, so that the spiral blade 503 hits the guide main plate 201 many times during the rotation process. The guide main plate 501 increases the thrust of the spiral blade 503 through the arc side, and then the guide main plate 201 moves inside the slide rail 203 through the slider 202 and enters the bottom of the feed bin 2. The reset spring 206 is continuously squeezed by the block 207 pushed by the feed bin 2, so that the guide main plate 201 cancels the squeezing of the reset spring 206 after entering the bottom of the feed bin 2, and the reset spring The spring 206 elastically pushes the card block 207 into the card slot on the outer side of the slide rail 202, thereby preventing the guide main plate 201 from affecting the rotation of the spiral blade 503. When the guide main plate 201 enters the feed bin 2, the guide main plate 201 fits with the auxiliary block 204 through the grooves on the upper and lower surfaces, and as the width of the auxiliary block 204 gradually widens from bottom to top, the auxiliary block 204 is made of rubber on one side adjacent to the guide sub-plate 205 during the process of the guide main plate 201 entering the feed bin 2. The auxiliary block 204 pushes the guide sub-plate 205 to move in the opposite direction through friction, and the two guide sub-plates 205 gradually intersect with the inclined side of the auxiliary block 204, thereby preventing the modified particles from continuing to fall.
