Description
Technical Field
The invention belongs to the technical field of building equipment manufacturing, and particularly relates to a storage mechanism for building powder, which is convenient to recycle.
Background
The building powder is stored in the storage bin, the air pump is used for pumping, and the air pressure of the storage bin is continuously increased in the powder conveying process, so that the storage bin is prevented from being damaged or even exploded due to high pressure, and a step of exhausting air is needed, and meanwhile, part of air in the storage bin is exhausted, so that the building powder is not used, and is lost and wasted, the use efficiency of production materials of enterprises is greatly reduced, the environment is polluted, and the requirements of the environment protection policy advocated in China at present are not met.
Disclosure of Invention
The invention aims to solve the problems, and provides a storage mechanism for building powder, which is reasonable in design and convenient to recycle, and solves the problem of building powder loss caused by exhaust in a storage bin.
In order to achieve the above purpose, the present invention adopts the following technical scheme: the invention relates to a storage mechanism for building powder convenient to recycle, which comprises a feeding pipe and a storage bin, wherein one end of the feeding pipe is communicated with the top of the storage bin, and at least one feeding pump is arranged on the feeding pipe, and is characterized in that: at least one recovery through hole for communicating with one end of a powder recovery pipe is formed in the inner side of the storage bin, and the other end of the powder recovery pipe is communicated with the top of the storage bin. The arrangement of the powder recovery pipe is not only beneficial to the discharge of the air pressure in the storage bin, but also ensures that the powder in the discharged air can return to the storage bin again through the opposite lower end or the opposite upper end of the recovery pipe, thereby ensuring that the powder can be recovered and can not be lost along with the discharge of the air.
Preferably, the powder recovery pipe comprises a first pipe section vertically upwards arranged and a second pipe section obliquely downwards arranged and communicated with the first pipe section, wherein the relatively lower end of the first pipe section is communicated with the recovery through hole, and the relatively lower end of the second pipe section is communicated with the top of the storage bin. The exhaust gas in the first pipe section which is vertically upwards arranged is utilized to consume the movement speed of the exhaust gas in the process of pushing the powder carried by the exhaust gas to upwards move, so that part of the powder in the exhaust gas can be gradually deposited, and finally can fall back into the storage bin, and meanwhile, the rest part of the powder which is not deposited can flow into the storage bin again through the second pipe section which is obliquely downwards arranged, so that the powder carried along with the exhaust gas is prevented from being lost.
Preferably, a first expansion part expanding towards the first pipe section direction is arranged between the first pipe section and the recovery through hole. The arrangement of the first expansion part further delays the running speed of the exhaust gas, thereby being beneficial to the precipitation of the powder carried by the exhaust gas.
Preferably, a second expansion part expanding towards the second pipe section is arranged between the first pipe section and the second pipe section. The provision of the second expansion portion further reduces the flow rate of the exhaust gas passing through the first pipe section so that the remaining powder in the exhaust gas can settle and flow back into the storage bin along the second pipe section.
Preferably, the cross-sectional area of the port at the relatively large end of the first flared portion is 1.7 times to 2.5 times the cross-sectional area of the port at the relatively small end; the cross-sectional area of the port at the relatively large end of the second flared portion is 1.1 times to 1.3 times the cross-sectional area of the port at the relatively small end. Since the flow rate of the exhaust gas at the first flare is higher than the flow rate of the exhaust gas at the second flare, the ratio of the cross-sectional area of the port at the relatively large end of the first flare to the cross-sectional area of the port at the relatively small end is greater than the ratio of the cross-sectional area of the port at the relatively large end of the second flare to the cross-sectional area of the port at the relatively small end.
Preferably, a first recovery filter screen with the shape and the size matched with the first recovery filter screen is arranged in the relatively small end of the first flaring part; and a second recovery filter screen with the shape and the size matched with the second flared part is arranged in the relatively small end of the second flared part. The first recovery filter screen and the second recovery filter screen not only retard the flow rate of the exhaust gas, but also block part of the powder in the exhaust gas to precipitate.
Preferably, the first recovery filter screen is provided with a first rotating shaft which is rotationally connected with the first flaring part along the middle line direction; the second recovery filter screen is provided with a second rotating shaft which is rotationally connected with the second flaring part along the middle line direction. The first recovery filter screen and the second recovery filter screen are pushed by the exhaust gas so that the first rotating shaft and the second rotating shaft rotate, the kinetic energy of the exhaust gas is further consumed, and the flow rate of the exhaust gas is reduced.
Preferably, the included angle between the center line of the port at the relatively large end of the first flaring portion and the center line of the port at the relatively small end is 52-68 degrees, and the middle part of the first flaring portion is convexly arranged above the connecting line of the center of the port at the relatively large end and the center of the port at the relatively small end in the first flaring portion. The flow rate of the exhaust gas is further delayed by changing the running direction of the exhaust gas, and meanwhile, the flow path of the exhaust gas in the powder recovery pipe is increased.
Preferably, the included angle between the center line of the port at the relatively large end of the second flaring portion and the center line of the port at the relatively small end is 45 degrees to 60 degrees, and the middle part of the first flaring portion is convexly arranged above the connecting line of the center of the port at the relatively large end and the center of the port at the relatively small end in the second flaring portion. The running direction of the exhaust gas is changed, which is favorable for delaying the flow velocity of the exhaust gas and increasing the flow path of the exhaust gas in the powder recovery pipe.
Preferably, one end of the powder recovery pipe communicated with the top of the storage bin is provided with a return sleeve which is communicated with the return sleeve and made of linen, a ring-shaped channel for the ring-shaped elastic rubber band to penetrate is sewn on the peripheral side of the port at the lower end of the return sleeve, and the area of the cross section in the ring-shaped channel is smaller than that of the cross section of the return sleeve at the port at the lower end of the return sleeve. The arrangement of the material returning sleeve made of the linen greatly reduces the reverse channeling of the gas outside the material returning sleeve, so that the powder coming out of the powder recycling pipe can better enter the storage bin.
Compared with the prior art, the storage mechanism for the building powder convenient to retrieve has the advantages that: the exhaust gas in the first pipe section which is vertically upwards arranged gradually consumes the kinetic energy of the exhaust gas in the process of pushing the powder carried by the exhaust gas to upwards move, so that the running speed of the exhaust gas is delayed, a part of powder in the exhaust gas can be gradually precipitated and finally can fall back into the storage bin, and meanwhile, the rest part of powder which is not precipitated can flow into the storage bin again through the second pipe section which is obliquely downwards arranged, so that the powder carried along with the exhaust gas is prevented from being lost.
