Centrifugal spray dryer with adjustable air inlet angle

Abstract

This utility model relates to the field of centrifugal spray dryer technology and discloses a centrifugal spray dryer with adjustable air inlet angle, including a feeding tank, a drying tank, and a storage tank. Two ropes, No. 1 and No. 2, are connected to both sides of the air seat. Since the planes of the two rotating seats are perpendicular to the planes of the No. 1 and No. 2 ropes can control the rotation of the air seat around the rotating seats, thereby adjusting the air inlet angle of the centrifugal spray dryer. By rotating the positioning bolt within the threaded seat, the No. 1 rope is pulled to move, changing the rotation angle of the air seat. Simultaneously, when the positioning pin is pushed upwards so that its upper teeth disengage from the toothed ring, the limiting seat can be further rotated to achieve rotation of the air seat on the vertical plane. When the positioning pin is released, it will position the limiting seat under the action of the supporting spring.

Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal spray dryers, specifically a centrifugal spray dryer with adjustable air inlet angle. Background Technology

[0002] Centrifugal spray dryers use centrifugal atomizers to dry liquid materials. They are suitable for producing powdered or granular products from solutions, emulsions, suspensions, and pumpable laminar liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density, and particle shape meet precise standards.

[0003] Chinese patent CN219879101U discloses a centrifugal spray dryer with adjustable air inlet angle, comprising a base, a main tower above the base, a collection mechanism below the main tower, a dust removal mechanism inside the main tower, and a storage box. The storage box has a duct on its lower left side, a first motor inside the duct, a first fixing rod on its circumferential surface, and an end of the first fixing rod away from the motor connected to the inner surface of the duct. The output end of the first motor is connected to a first rotating rod via a coupling, and the circumferential surface of the first rotating rod has helical blades. The storage box is slidably connected to the lower interior of the storage box, and a collection pipe is located on the upper left side of the storage box. The pressure inside the storage box is reduced by the cooperation of the first motor, the first rotating rod, and the helical blades. The collection pipe causes the storage box to exert suction on the main tower, thereby collecting the dried material inside the main tower.

[0004] The aforementioned dryer has the effect of reducing pressure, but the drying effect of the material during use is affected by the wind direction and wind force. Since the existing dryer only provides a fixed direction of wind for drying, the drying effect of the material is not good. Therefore, it is necessary to provide a centrifugal spray dryer with an adjustable air inlet angle. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal spray dryer with an adjustable air inlet angle to solve the problem that existing dryers only provide a fixed airflow direction for drying, resulting in poor drying effect of materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal spray dryer with adjustable air inlet angle, comprising a feeding tank, a drying tank, and a storage tank. An air duct is fixedly installed on one side of the drying tank, a heating element is fixedly installed at one end of the air duct, and an air pump is fixedly installed at one end of the heating element. An adjustment mechanism is provided on the air duct. The adjustment mechanism includes a limiting seat, which is rotatably mounted on the drying tank. A corrugated pipe is fixedly installed at one end of the air duct. Two rotating seats are fixedly mounted side-by-side on one side of the limiting seat. An air seat is rotatably mounted between the two rotating seats and fixedly mounted on the corrugated pipe. A first rope is rotatably mounted on one side of the air seat and passing through the limiting seat, and a second rope is rotatably mounted on the other side of the air seat and passing through the limiting seat. A buffer spring is fixedly installed between the second rope and the limiting seat.

[0007] Preferably, the air duct is fixedly installed through the middle of the limiting seat, and the plane where the two rotating seats are located is perpendicular to the plane where the first rope and the second rope are located.

[0008] Preferably, the front inner diameter of the wind seat is larger than the rear inner diameter, and the length of the first rope is greater than the length of the second rope.

[0009] Preferably, the limiting seat is provided with a positioning mechanism, the positioning mechanism including a threaded seat, the threaded seat is fixedly installed on one side of the limiting seat, and a positioning bolt is installed inside the threaded seat and threaded onto a No. 1 rope. A slide is fixedly installed through the upper part of the drying tank, a positioning column is slidably installed inside the slide, and a support spring is fixedly installed between the positioning column and the slide.

[0010] Preferably, one end of the first rope is fixedly installed with a shaped block, and one end of the positioning bolt is rotatably connected to the first rope through the shaped block.

[0011] Preferably, a toothed ring is fixedly installed in the middle of the limiting seat, and a plurality of teeth are fixedly installed at the front end of the positioning post, and the toothed ring and the teeth are adapted to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) The centrifugal spray dryer with adjustable air inlet angle is connected to both sides of the air seat by rope No. 1 and rope No. 2 respectively.

[0014] 2) This centrifugal spray dryer with adjustable air inlet angle moves by rotating the positioning bolt in the threaded seat, thereby pulling the No. 1 rope to move and changing the rotation angle of the air seat. At the same time, when the positioning column is pushed upward so that its upper teeth disengage from the toothed ring, the limiting seat can be further rotated to achieve rotation on the vertical plane of the air seat. When the positioning column is released, the positioning column will play a positioning role on the limiting seat under the action of the support spring. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4A centrifugal spray dryer with adjustable air inlet angle includes a feeding tank 1, a drying tank 2, and a storage tank 3. An air duct 4 is fixedly installed on one side of the drying tank 2, a heating pipe 5 is fixedly installed at one end of the air duct 4, and an air pump 6 is fixedly installed at one end of the heating pipe 5. An adjustment mechanism 7 is provided on the air duct 4. The adjustment mechanism 7 includes a limiting seat 701, which is rotatably installed on the drying tank 2. A corrugated pipe 702 is fixedly installed at one end of the air duct 4. Two rotating seats 703 are fixedly installed side by side on one side of the limiting seat 701. An air seat 704 is rotatably installed between the two rotating seats 703 and fixedly installed on the corrugated pipe 702. A first rope 705 is rotatably installed on one side of the air seat 704 and through the limiting seat 701, and a second rope 706 is rotatably installed on the other side of the air seat 704 and through the limiting seat 701. A buffer spring 707 is fixedly installed between the second rope 706 and the limiting seat 701.

[0023] See Figure 2 and Figure 3 Furthermore, it is found that the air duct 4 is fixedly installed in the middle of the limiting seat 701, the plane where the two rotating seats 703 are located is perpendicular to the plane where the first rope 705 and the second rope 706 are located, the front inner diameter of the air seat 704 is larger than the rear inner diameter, and the length of the first rope 705 is greater than the length of the second rope 706.

[0024] Specifically, the wind seat 704 is connected to both sides by rope 705 and rope 706 respectively. Since the planes of the two rotating seats 703 are perpendicular to the planes of rope 705 and rope 706, rope 705 and rope 706 can control the wind seat 704 to rotate around the rotating seats 703. Since the length of rope 705 is greater than the length of rope 706, when the front ends of rope 705 and rope 706 are aligned, rope 706 will tilt the wind seat under the action of the buffer spring 707.

[0025] Example 2

[0026] Combination Figure 1 and Figure 4 The limiting seat 701 is provided with a positioning mechanism 8, which includes a threaded seat 801. The threaded seat 801 is fixedly installed on one side of the limiting seat 701, and a positioning bolt 802 is threadedly installed inside the threaded seat 801 and sleeved on the first rope 705. A slide 803 is fixedly installed through the upper part of the drying tank 2. A positioning column 804 is slidably installed inside the slide 803. A support spring 805 is fixedly installed between the positioning column 804 and the slide 803.

[0027] See Figure 4Furthermore, based on Embodiment 1, it is further found that one end of the first rope 705 is fixedly installed with a shaped block, and one end of the positioning bolt 802 is rotatably connected to the first rope 705 through the shaped block. A toothed ring is fixedly installed in the middle of the limiting seat 701, and several teeth are fixedly installed at the front end of the positioning column 804, and the toothed ring and teeth are compatible.

[0028] Specifically, the first rope 705 is rotatably connected to the positioning bolt 802 by means of a special-shaped quick-connect, and the positioning bolt 802 is threadedly installed in the threaded seat 801. In use, the positioning bolt 802 can be rotated to move within the threaded seat 801, thereby pulling the first rope 705 to move, changing the rotation angle of the wind seat 704. At the same time, when the positioning pin 804 is pushed upward so that its upper teeth disengage from the toothed ring, the limiting seat 701 can be further rotated to achieve rotation of the wind seat 704 on the vertical plane. When the positioning pin 804 is released, the positioning pin 804 will play a positioning role on the limiting seat 701 under the action of the supporting spring 805.

[0029] In actual operation, the two sides of the wind seat 704 are connected by rope 705 and rope 706 respectively. Benefiting from the fact that the plane of the two rotating seats 703 is perpendicular to the plane of rope 705 and rope 706, rope 705 and rope 706 can control the wind seat 704 to rotate around the rotating seat 703. Since the length of rope 705 is greater than the length of rope 706, when the front ends of rope 705 and rope 706 are aligned, rope 706 will tilt the wind seat under the action of buffer spring 707.

[0030] The first rope 705 is rotatably connected to the positioning bolt 802 by means of a special-shaped quick-connect, and the positioning bolt 802 is threadedly installed in the threaded seat 801. In use, the positioning bolt 802 can be rotated to move within the threaded seat 801, thereby pulling the first rope 705 to move and changing the rotation angle of the wind seat 704. At the same time, when the positioning pin 804 is pushed upward so that its upper teeth disengage from the toothed ring, the limiting seat 701 can be further rotated to achieve rotation of the wind seat 704 on the vertical plane. When the positioning pin 804 is released, the positioning pin 804 will play a positioning role for the limiting seat 701 under the action of the supporting spring 805.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
