Background technique

The garbage pneumatic conveying system was invented by a Swedish company in 1961. It was first used for hospital garbage collection, and it has been assembled and used in residential areas since 1967. At present, it has been promoted to more than 30 countries and regions including the United States, Japan, Germany, Denmark, Singapore, and Hong Kong Special Administrative Region of China, with hundreds of sets installed and running. In recent years, domestic applications have developed rapidly, and several sets have been put into operation. The gas-solid separation device is one of the key equipment of the garbage pneumatic conveying system, which is crucial to the successful and stable operation of the system. In order to prevent the garbage from being sucked away from the exhaust outlet of the general cyclone separator, a simple filter is set at the outlet of the exhaust pipe to block the garbage and separate it from the air flow, which has the following disadvantages: the filter is easy to be blocked and damaged, and it is not easy to clean. Replacement and maintenance The workload is heavy; the pore size of the filter is not easy to determine, and there are disadvantages if the pore size is too large or too small.

Chinese utility model patent 200520055507.3 discloses a gas-solid separation device for a garbage pneumatic conveying system. Its main feature is that a mesh cylinder is arranged at the outlet of the exhaust pipe to block garbage, and a high-pressure air pipe is installed to prevent garbage from blocking the mesh. Perform mesh self-cleaning.

Utility model content

The purpose of this utility model is to provide a gas-solid separation device for a garbage pneumatic conveying system. clean up.

The above-mentioned purpose of the utility model is achieved through the following technical solutions:

A gas-solid separation device of a garbage pneumatic conveying system, comprising a separator cylinder part, a separator cone part, an air inlet, an air outlet, a rotating cage, a pneumatic valve, etc., and the air inlet is arranged in the middle of the separator cylinder part, The air outlet is set on the top of the separator cylinder part, the separator cone part is connected under the separator cylinder part, the rotating cage is set at the air outlet, and the pneumatic valve is set at the bottom of the separator cone part.

The rotating cage is a cylindrical structure, its diameter is slightly larger than that of the air outlet, and it is located directly below the air outlet. The grid gap of the rotating cage is 20-40mm. Preferably, the grid gap of the rotating cage is 30 mm, the diameter is 600 mm, and the height is 600 mm.

The rotating cage is driven to rotate by the air outlet and the air flow inside the cyclone separator, without being driven by a motor.

A garbage storage bucket is also provided under the cone part of the separator, and a pneumatic valve is arranged between the garbage storage bucket and the cone part of the separator.

The bottom of the garbage storage bucket is also provided with a pneumatic valve. Two pneumatic valves are used to collect and empty waste in the waste hopper.

The beneficial effect of the utility model is that on the basis of the ordinary cyclone separator, a rotating cage is arranged at the air outlet to replace the filter screen or the mesh cylinder, and the rotating cage is driven to rotate without connecting the motor, and the air flow inside the air outlet and the cyclone separator Drive the rotation, and the fast-rotating rotating cage plays the role of intercepting garbage and separating it from the air flow. Due to the large gap and fast rotation of the rotating cage, it is not easy to be blocked and basically does not need to be cleaned. No external power is needed, and the problem of blockage cleaning is solved.

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it does not mean that the protection scope of the utility model is limited.

Detailed ways

As shown in Figure 1, it is a schematic structural diagram of the gas-solid separation device of the utility model garbage pneumatic conveying system, wherein, 1 is the separator cylinder part, 2 is the separator cone part, 3 is the air inlet, 4 is the air outlet, 5 is a rotating cage, 6 is an A pneumatic valve, and 7 is a B pneumatic valve.

The gas-solid separation device of the garbage pneumatic conveying system of the utility model includes a separator cylinder part 1, a separator cone part 2, an air inlet 3, an air outlet 4, a rotating cage 5, A pneumatic valve 6, and B pneumatic valve 7 etc., the air inlet 3 is arranged in the middle of the separator cylinder part 1, the air outlet 4 is arranged on the top of the separator cylinder part 1, the separator cone part 2 is connected under the separator cylinder part 1, and the rotating cage 5 is arranged At the air outlet 4, between the A pneumatic valve 6 and the B pneumatic valve 7 is a garbage storage bucket, the garbage storage bucket is arranged under the cone part 2 of the separator, and a The B pneumatic valve 7 is also provided with an A pneumatic valve 6 at the bottom of the garbage storage bucket.

The rotating cage 5 is a cylindrical structure, and its diameter is slightly larger than that of the air outlet. The gap between the bars of the rotating cage 5 is 20-40mm, preferably, the gap between the bars of the rotating cage 5 is 30mm, the bars are straight steel pipes with a diameter of 15mm, the diameter of the rotating cage is 600mm, and the height is 600mm. The rotating cage 5 is located directly below the air outlet 4, and is driven to rotate by the air outlet 4 and the internal air flow of the cyclone separator without being driven by a motor.

The high-speed air and garbage enter the cyclone separation area through the air inlet 3. The air inlet 3 is set in the middle of the separator cylinder part 1. The airflow will change from linear motion to circular motion. The airflow containing garbage will generate centrifugal force during the rotation process, and the garbage will be thrown away. to the wall. When the rubbish contacts the wall, it loses the inertial force and falls along the wall by the momentum of the inlet velocity and the downward gravity, and enters the bottom of the cone part 2 of the separator. Part of the garbage that has not been separated by the cyclone moves with the airflow, and is intercepted by the rapidly rotating rotating cage 5 before entering the air outlet 4, and is thrown towards the wall along the wall and falls into the bottom of the separator cone part 2 to separate the garbage from the airflow. At this time, the B pneumatic valve 7 is in the open state, and the A pneumatic valve 6 is in the closed state. When the garbage at the bottom of the separator cone part 2 accumulates to a certain amount, the B pneumatic valve 7 is closed, and the A pneumatic valve 6 is opened. After emptying the garbage, The A pneumatic valve 6 is closed, and the B pneumatic valve 7 is opened to complete a cycle.

Based on the common cyclone separator, the utility model is provided with a rotating cage 5 at the air outlet 4 to replace the filter screen, and the rotation is driven by the air outlet and the internal airflow of the cyclone separator to intercept garbage and separate it from the airflow. At the same time, the rotating cage 5 is not easy to block because of the large gap and high-speed rotation, and basically does not need to be cleaned. No external power is needed, and the problem of blockage cleaning is solved.
