Description

Technical Field

[0001] The invention relates to the technical field of gas emission spray dust removal devices, and in particular to a sesame processing gas emission spray dust removal device. Background Art

[0002] Sesame is one of the main oil crops in China and is also the leader of the four major edible oil crops. Its processing process includes screening, seed frying, smoke raising and cooling, etc. Dust and oil smoke will be generated during screening and seed frying. This oil smoke exhaust gas needs to be dust-removed and meet the emission standards before it can be discharged. The existing sesame processing gas treatment often adopts a spraying method for dust removal. The Chinese patent announcement number CN217594232U discloses a sesame processing gas emission spray dust removal device, including a water tank, a treatment box is fixedly connected to the top of the water tank inner cavity, a first filter plate is fixedly connected between the top and bottom right sides of the water tank inner cavity, the left side of the bottom of the treatment box is connected to the water tank, the left side of the treatment box inner cavity is fixedly connected to an equipment box, and the top and bottom right sides of the equipment box are fixedly connected to second filter plates. The invention solves the problem that the existing gas emission spray dust removal device cannot automatically clean the filter plate and has a poor treatment effect.

[0003] In the above-mentioned prior art, this sesame processing gas emission spray dust removal device has the following problems when treating the high-temperature oil-containing waste gas generated by sesame processing. First, the waste gas is introduced from bottom to top, so that the escape velocity of the expanded high-temperature waste gas during spraying is faster, and the contact time with the spray water is shorter, which affects the spray effect. Second, the filter plate is automatically cleaned by an external power supply plus a cleaning brush, which increases the processing cost. A large amount of dust adheres to the cleaning brush, which often needs to be replaced and maintained, and is not convenient to use. Third, the high-temperature waste gas generated by sesame processing contains sesame oil particles. Due to the nature of oil being insoluble in water, the spray dust removal effect is not good. For this reason, a sesame processing gas emission spray dust removal device is proposed. Summary of the invention

[0004] The invention aims to solve the following problems in the existing sesame processing gas emission spray dust removal device when treating the high-temperature oil-containing waste gas generated by sesame processing: first, the waste gas is introduced from bottom to top, so that the escape velocity of the expanded high-temperature waste gas during spraying is faster, and the contact time with the spray water is shorter, which affects the spray effect; second, the filter plate is automatically cleaned by means of an external power supply and a cleaning brush, which increases the processing cost, a large amount of dust adheres to the cleaning brush, and it often needs to be replaced and maintained, which is not convenient to use; third, the high-temperature waste gas generated by sesame processing contains sesame oil particles, and due to the property that oil is insoluble in water, the spray dust removal effect is not good. The present invention provides a sesame processing gas emission spray dust removal device.

In addition, the sliding of the water spray mechanism drives the transmission mechanism to move, and the movement of the transmission mechanism drives the filter mechanism to flip for filtering. When the water spray mechanism stops sliding, the waste gas in the spray box is sprayed with dust reduction by the water spray mechanism, and the gas after spraying and dust reduction is discharged through the air outlet mechanism, and the oil fume is cooled during the discharge process, so that the oil gas is cooled into oil droplets on the air outlet mechanism, and slides down to the oil collection mechanism under the action of gravity for recovery. After the spraying is completed, the spray mechanism is reset, and the filter mechanism is driven to flip according to the above principle to pour out the filtered dust and backwash the filter mechanism, thereby realizing an automatic cleaning process, which improves the practicability and ease of use of the device.

The pump draws the water in the filter box into the cavity tube through the connecting pipe and the connecting hose. At this time, the valve on the spray head is closed. As the amount of water in the cavity tube increases, the gravity of the cavity tube increases, causing the cavity tube and the sliding rod to slide on the connecting ear plate. When the water in the cavity tube is full, the valve is opened, and water mist can be sprayed through the spray head to remove dust from the high-temperature exhaust gas in the spray box.

A connecting rod is mounted on the placing ring, and an oil collecting box is mounted on the connecting rod. The oil collecting box is located on the bottom side of the hollow tube, and the oil collecting box is matched with the inner diameter of the hollow tube. During spray dust removal, the oil collecting box is passed through the hollow tube and placed into the bottom side of the hollow tube. At this time, the placing ring is located on the top side of the hollow tube. The oil fume particles are cooled down on the hollow tube and become oil droplets.

The sliding of the sliding block 1006 drives the connecting shaft 1009 to slide in the threaded slide groove 1011, thereby driving the driving roller 1010 to rotate in the limiting cylinder 1007. When the driving roller 1010 rotates 180 degrees, the driving roller 1010 is driven to rotate in the limiting cylinder 1007. The adapter shaft block 1015 on the movable roller 1010 coincides with the limiting straight groove 1014, and the sliding block 1006 continues to slide. At this time, under the limiting effect of the limiting straight groove 1014, the connecting shaft 1009 remains stationary in the threaded groove 1011 and drives the transmission roller 1010 to slide in the limiting cylinder 1007 until the connecting shaft 1009 falls into the first annular groove 1012 or the second annular groove 1013 again. According to the above principle, the sliding block 1006 continues to slide to drive the transmission roller 1010 to rotate 180 degrees, thereby driving the rotating shaft 902 to rotate 180 degrees when sliding and resetting in the cavity cylinder 605 to realize the automatic flipping function.

The limiting square rod 1016 is slidably installed in the adapting groove 1017. Through the setting of the limiting square rod 1016 and the adapting groove 1017, the sliding of the driving roller 1010 on the limiting cylinder 1007 is facilitated, and at the same time, when the driving roller 1010 rotates, the rotating shaft 902 is driven to rotate, which further improves the scientificity and practicality of the structure.
