Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology and relates to a centrifugal drying device. Background Technology

[0002] Automotive parts, also known as auto components, auto parts, or auto spare parts, refer to the components that make up the various units of a car and all consumable materials that serve the car. They are characterized by a wide variety, complex substitutes, complex identification systems, and rapidly fluctuating prices. Typically, after automotive parts are manufactured, they undergo passivation, which involves oxidizing the parts with strong oxidants or using electrochemical methods to make the surface inactive and less susceptible to oxidation, thus slowing down the corrosion rate of the metal. After cleaning, residual water stains remain on the surface of the automotive parts, requiring centrifugal drying.

[0003] Existing centrifugal drying devices include an outer drum, a porous inner drum, and a hot air blowing duct located above the outer drum. After the automotive parts to be dried are placed in the inner drum, the duct can be rotated to another position, allowing the inner drum to be placed on a support frame inside the outer drum. Before starting the centrifuge, the duct can be rotated above the outer drum. During centrifugal drying, the inner drum rotates under the drive of a motor, expelling moisture. Simultaneously, hot air blown from the outer drum into the outer drum carries away moisture from inside. The hot air also raises the temperature of the automotive parts, accelerating evaporation on their surface, thus achieving the drying purpose. However, currently, during centrifugal drying, the outer drum is open. The hot air blowing duct into the open outer drum causes some hot air to escape from the opening, resulting in heat loss and making the device insufficiently energy-efficient. Utility Model Content

[0004] The purpose of this invention is to provide a centrifugal drying device that aims to solve the problem of insufficient energy efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a centrifugal drying device, including an outer barrel and a hot air duct that blows out hot air. The hot air outlet of the hot air duct can be rotated to the top of the outer barrel or outside the outer barrel. It also includes a sleeve and a sleeve spring movably sleeved on the outer wall of the hot air outlet, and a barrel cover that is movably closed to the top of the outer barrel and disposed on the outer wall of the sleeve. The two ends of the sleeve spring are respectively connected to the outer wall of the hot air duct and the top of the sleeve. It also includes an air baffle ring disposed on the inner wall of the sleeve. An air outlet is opened at the bottom of the side of the outer barrel.

[0006] Furthermore, the height of the smaller diameter portion of the wind-blocking ring is less than the height of the larger diameter portion of the group of wind rings.

[0007] Furthermore, it also includes a rotatable rotating frame disposed inside the outer barrel, a porous inner barrel movably placed inside the rotating frame, an insertion strip disposed on the outside of the inner barrel, and an insertion slot correspondingly provided on the rotating frame, the insertion strip and the insertion slot being movably engaged.

[0008] Furthermore, the rotating frame includes a support plate, a plurality of vertical plates disposed on the outer periphery of the support plate, and a horizontal ring connected to the plurality of vertical plates, wherein the insertion slot is vertically formed on the vertical plate.

[0009] Furthermore, it also includes a plurality of rotatable support wheels disposed at the bottom and sides inside the outer barrel, wherein the wheel surfaces of a portion of the support wheels are in contact with the support hole plate, and the wheel surfaces of another portion of the support wheels are in contact with the transverse ring.

[0010] Furthermore, there are three support wheels located at the bottom inside the outer barrel and three support wheels located on the sides inside the outer barrel, all arranged in an equilateral triangle with the axis of the outer barrel as the same center.

[0011] Furthermore, it also includes an air outlet duct connected to the air outlet and an exhaust fan connected to the air outlet duct.

[0024] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the centrifugal drying apparatus proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0025] This utility model provides a centrifugal drying device, for reference... Figures 1 to 6The system includes an outer tub 1, a rotatable rotating frame 8 disposed within the outer tub 1, a porous inner tub 9 movably placed within the rotating frame 8, and a hot air duct 2 for blowing out hot air. An insertion strip 10 is provided on the outside of the inner tub 9, and an insertion slot 11 is correspondingly provided on the rotating frame 8. The insertion strip 10 and the insertion slot 11 are movably engaged. Thus, before centrifugally drying automotive parts, the automotive parts can be placed in the inner tub 9, and then the inner tub 9 can be placed in the rotating frame 8. The rotatable rotating frame 8 can drive the inner tub 9 to rotate for centrifugation of the automotive parts. It also includes a vertically arranged... The system includes a vertical cylinder 21 on the ground and a column 22 that movably fits against the inner wall of the cylinder 21. The hot air duct 2 includes a horizontal air supply duct 23 connected to the top of the column 22. This allows the hot air outlet 6 of the hot air duct 2 to be rotated above or outside the outer cylinder 1, thus not obstructing the placement of the inner cylinder 9 in the rotating frame 8. Specifically, before placing or removing the inner cylinder 9, the hot air outlet 6 of the hot air duct 2 is rotated outside the outer cylinder 1. After the placement or removal is completed, when centrifugal drying needs to be started, the hot air outlet 6 of the hot air duct 2 is rotated... The 6-section rotates to the top of the outer tub 1, and also includes a sleeve 3 and a sleeve spring 4 movably fitted onto the outer wall of the hot air outlet 6, and a tub lid 5 (both the sleeve 3 and the tub lid 5 are made of lightweight material) that is movably closed onto the top of the outer tub 1 and mounted on the outer wall of the sleeve 3. The two ends of the sleeve spring 4 are respectively connected to the outer wall of the hot air duct 2 and the top of the sleeve 3. It also includes a wind-blocking ring 7 mounted on the inner wall of the sleeve 3. The height of the smaller diameter portion of the wind-blocking ring 7 is less than the height of the larger diameter portion of the wind-blocking ring. Thus, when the hot air duct 2 is not blowing hot air, the sleeve spring... 4. The sleeve 3 can be pulled up. The position of the barrel cover 5, which is connected to the outer wall of the sleeve 3, is also high and does not contact the top of the outer barrel 1. After hot air is blown out of the hot air duct 2, part of the hot air flow is blown to the wind baffle ring 7 and blocked, generating a downward force. This force will cause the position of the sleeve 3 to drop, thereby causing the position of the barrel cover 5 to drop and cover the top of the outer barrel 1. The opening and closing of the barrel cover 5 is achieved through its own structure without manual operation. The structure is ingeniously designed. The design of the barrel cover 5 allows all the hot air blown out of the hot air duct 2 to be blown into the outer barrel 1, making full use of the heat of the hot air, which is more energy-efficient and the centrifugal drying efficiency is also higher.

[0026] Specifically, the hot air blown out by the hot air duct 2 is achieved by existing equipment, such as heating wires installed on the inner wall of the hot air duct 2 to heat the blown airflow, and the blown airflow can be achieved by a blower device such as a blower.

The insertion slot 11 is vertically opened on the vertical plate 8b.

[0028] refer to Figure 3 It also includes a plurality of rotatable support wheels 12 disposed at the bottom and sides inside the outer barrel 1. Some of the wheel surfaces of the support wheels 12 are in contact with the support hole plate 8a, and the wheel surfaces of the other part of the support wheels 12 are in contact with the transverse ring 8c. In this way, the rotatable support wheels 12 can support the rotating frame 8 that rotates during centrifugation, making its position more stable and safer. At the same time, the support wheels 12 themselves can rotate, so the friction between them and the rotating frame 8 is very small, thus reducing structural wear.

[0029] refer to Figure 2 The support wheel 12 can be connected to the two opposite inner sides of the U-shaped piece 28 located on the bottom and side of the outer barrel 1 via the central shaft, thereby realizing the rotation of the support wheel 12.

[0030] refer to Figure 3 and Figure 4 The support wheels 12 located at the bottom inside the outer barrel 1 and the support wheels 12 located on the side inside the outer barrel 1 are each provided in threes, and are distributed in an equilateral triangle with the axis of the outer barrel 1 as the same center. Other numbers can also be used, which can be evenly distributed radially with the axis of the outer barrel 1 as the center, so that the rotating frame 8 is evenly stressed and its position is stable.

[0031] In one embodiment, reference Figure 2 The hot air duct 2 does not have an exhaust device, but also includes an air outlet duct 14 connected to the air outlet 13 and an exhaust fan 15 connected to the air outlet 14. This can create convection, increase the airflow speed, and thus improve the drying efficiency.

[0032] In another embodiment, the hot air duct 2 is provided with an exhaust device, and also includes an air outlet duct 14 connected to the air outlet 13 and an exhaust fan 15 connected to the air outlet 14, which can further increase the airflow speed and thus improve the drying efficiency.

[0033] refer to Figure 2 The output shaft of the motor 18 is also connected to the impeller of the exhaust fan 15, so that the exhaust fan 15 does not need to provide additional power, which is more energy-efficient.

[0034] refer to Figure 2It also includes a rotatable rotating shaft 16, the bottom center of the rotating frame 8 is connected to the bottom center of the inner tub 1 through the rotating shaft 16, a transmission wheel 17 is provided on the rotating shaft 16, a motor 18 is provided outside the outer tub 1 and a rotating wheel 19 is connected to the output shaft of the motor 18, and a transmission belt 20 is provided. The transmission belt 20 is sleeved on the wheel surfaces of the transmission wheel 17 and the rotating wheel 19. After the motor 18 is started, it drives the output shaft to rotate, the output shaft drives the rotating wheel 19 to rotate, the rotating wheel 19 drives the transmission wheel 17 to rotate through the transmission belt 20, the transmission wheel 17 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the rotating frame 8 to rotate.

It also includes a snap-on torsion spring 26 and an inverted L-shaped fastener 27. The two support legs of the snap-on torsion spring 26 are respectively connected to the bottom of the receiving groove 25 and the fastener 27. The fastener 27 can lock the handle 24 in a position that fits against the top of the inner tub 9. The shape of the part of the handle 24 that is fastened by the fastener 27 is V-shaped. When it is necessary to lift the inner tub 9, the handle 24 can be used to lift it. During centrifugation, the fastener 27 can lock the handle 24 in a position that fits against the top of the inner tub 9 to prevent it from standing up under the action of centrifugal force.

[0037] Specifically, a horn-shaped expansion member and a T-shaped member (not shown in the figure) connected to the top of the expansion member can be provided. The two ends of the T-shaped member are in contact with the inner wall of the sleeve.
