Description

Technical Field

[0001] This utility model relates to the field of perlite ore feeding technology, specifically a negative pressure feeding device for perlite ore. Background Technology

[0002] Existing perlite ore feeding systems typically employ traditional feeding methods, such as simple gravity feeding or fixed-speed mechanical conveying. These methods have several drawbacks, primarily including significant fluctuations in feed rate and the inability to precisely control raw material flow and quality, failing to meet the high-precision requirements of modern production processes for flow and quality control. This imprecise control not only affects product quality stability and production efficiency but may also lead to raw material waste and increased production costs.

[0003] To address the aforementioned issues, many manufacturers have introduced variable frequency motor-driven threaded conveyor systems to achieve precise material transport. However, these conveying devices are mostly single-frequency controlled, capable of only preliminary flow regulation and unable to achieve continuous monitoring and personalized adjustment of the flow rate throughout the entire transport process. This means that changes in material flow rate cannot be detected in real time during transmission, resulting in limitations in flow control and consequently affecting the accuracy and stability of the final material. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a multi-layer structure waste heat utilization heating electric drum.

[0005] To solve the above problems, the technical solution of this utility model is: a negative pressure feeding device for perlite ore, comprising: The elevator is equipped with a discharge pipe at its upper end and a packaging platform on one side of the elevator. The hopper is located on the side of the elevator away from the packaging platform. A first auger is connected to the lower port of the hopper, and a dust collector is installed on the top of the hopper. An electric slide gate valve is connected between the hopper and the first auger. The second auger is connected below the first auger.

[0006] Furthermore, the first auger includes: The first housing has an upper pipe connected to the lower end of the hopper; The first variable frequency motor is fixedly connected to one side of the first housing; The first threaded conveying rod is located in the first housing, and one end of the first threaded conveying rod penetrates the first housing and is fixedly connected to the drive end of the first variable frequency motor.

[0007] The first discharge pipe is connected to the lower side of the first housing, away from the first variable frequency motor.

[0008] Furthermore, the second auger includes: The second housing has a pipe connected to the first discharge pipe at one end of its upper side; The second variable frequency motor is fixedly connected to the end of the second housing near the first discharge pipe; The second threaded conveying rod is located in the second housing, and one end of the second threaded conveying rod penetrates the second housing and is fixedly connected to the drive end of the second variable frequency motor. The second discharge pipe is fixedly connected to the lower end of the second housing away from the second variable frequency motor.

[0009] The advantages of this invention compared to existing technologies are as follows: The advantage of this invention lies in its primary flow control achieved through the addition of an electric slide gate valve, combined with dual frequency conversion motors controlling the conveying speeds of the first and second screw conveyors respectively, thus realizing continuous and precise flow and quality control. This method not only ensures the stability and uniformity of raw materials during conveying but also reduces material loss and waste, improves production efficiency and product quality, and meets the stringent requirements of modern production processes for quantitative and qualitative control of materials. Simultaneously, the dust collector on the top of the silo creates a negative pressure for dust collection between the elevator and the silo. During the discharge process, dust is directly drawn away from the elevator and silo by the top dust collector, preventing external dust accumulation and improving the hygiene of the process.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1 As shown, the technical solution of this utility model is as follows: a negative pressure feeding device for perlite ore, comprising: a discharge pipe provided at the upper end of a hoist 1; a pier packaging platform 2 connected to one side of the hoist 1; a first auger 5 connected to the lower port of a silo 3; the silo 3 being used to store ore raw materials and ensure continuous feeding; a silo top dust collector 7 provided above the hoist 1; the silo top dust collector 7 creating a negative pressure for dust collection between the hoist 1 and the silo 3; dust generated during the feeding process being directly drawn away from the hoist 1 and the silo 3 by the silo top dust collector 7, preventing external dust; an electric slide valve 3 connected between the silo 3 and the first auger 5; and a second auger 6 connected below the first auger 5; the electric slide valve 3 controlling the initial flow rate of the raw materials.

[0014] like Figure 1 As shown, the first auger 5 includes a pipe connected to the lower end of the hopper 3 on the upper side of the first housing 501, a first variable frequency motor 502 fixedly connected to one side of the first housing 501, a first threaded conveying rod 503 located in the first housing 501, one end of the first threaded conveying rod 503 penetrating the first housing 501 and fixedly connected to the drive end of the first variable frequency motor 502, and a first discharge pipe 504 connected to the lower end of the first housing 501 away from the first variable frequency motor 502. The second auger 6 includes a pipe connected to the first discharge pipe 504 at one end of the upper side of the second housing 601, and a second variable frequency motor 602 fixedly connected to the end of the second housing 601 near the first discharge pipe 504. The second threaded conveying rod 603 is located in the second housing 601. One end of the second threaded conveying rod 603 penetrates the second housing 601 and is fixedly connected to the drive end of the second variable frequency motor 602. The second discharge pipe 604 is fixedly connected to the lower end of the second housing 601 away from the second variable frequency motor 602. When the first variable frequency motor 502 is started, it drives the first threaded conveying rod 503 to push the raw material falling into the first housing 501 to the first discharge pipe 504. The raw material flows into the second housing 601 through the first discharge pipe 504. When the second variable frequency motor 602 is started, it drives the second threaded conveying rod 603 to rotate and push the raw material to the second discharge pipe 604 to be discharged from the second housing 601.

[0015] In practical use, raw materials are loaded onto the packaging platform 2 and then lifted into the silo 3 by the elevator 1. Dust will be generated when the elevator 1 lifts the raw materials. The dust collector 7 on the top of the silo creates a negative pressure to suck up the dust inside the elevator 1 and the silo 3. The dust collector 8 directly removes the dust from the elevator 1 and the silo 3, preventing external dust. When the raw materials are stored in the silo 3, the flow rate is initially controlled by the electric slide valve 4. When the raw materials are placed into the first housing 501, the first variable frequency motor 502 controls the speed of the first threaded conveyor rod 503 to achieve flow control and weighing. When the raw materials flow into the second housing 601 through the first discharge pipe 504, the second variable frequency motor 602 is started to drive the speed of the second threaded conveyor rod 603 through its variable frequency control to achieve flow control and weighing again.
