Technical Field

[0001] The utility model belongs to the field of sodium bicarbonate processing, and in particular relates to a centrifuge feeding and spraying recovery device. Background Art

[0002] Sodium bicarbonate (baking soda) is a widely used leavening agent in the food industry. It is used in the production of biscuits, cakes, steamed buns, bread, etc. It is a generator of carbon dioxide in carbonated beverages.

[0003] In the process of preparing baking soda for food, a centrifuge is used to separate excess water to form powder blocks, which are then fed into the next step through a feeding belt. Currently, there is a large impact force when the centrifuge is fed to the belt, and materials are prone to flying, which not only pollutes the on-site working environment, but also easily causes material spillage and leakage, which wastes raw materials to a certain extent and also makes the metering accuracy low.

[0004] Therefore, we propose a centrifuge feeding and spraying recovery device to solve the above problems. Utility Model Content

[0005] In view of the large impact force when the centrifuge is unloaded to the belt, which easily causes the material to fly, not only polluting the on-site working environment, but also easily causing the problem of material spilling and leakage. The utility model provides a centrifuge unloading spray recovery device.

[0011] Preferably, two electric push rods are further included, and the two electric push rods are installed on the top of the splash cover, one on the left and one on the right.

[0014] Preferably, a plurality of connecting rods are installed between the fixing ring on the lower side and the inner edge of the bottom frame.

[0015] Preferably, one end of the negative pressure recovery pipe facing away from the dust suction pipe is connected to a fan or a vacuum cleaner.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model controls the synchronous extension of two electric push rods to drive the bottom frame to move downward, and makes the two sealing strips contact the front and rear frames of the belt conveyor respectively.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] See also Figure 1-3The utility model provides a technical solution for a centrifuge feeding and spraying recovery device:

[0026] Embodiment 1:

[0027] according to Figure 1-3 As shown, it includes a splash shield 1, a bottom frame 6 and a feed pipe 31. The bottom of the splash shield 1 is open, and a reserved hole is opened on the top.

[0028] At least one dust suction pipe 4 connected to a negative pressure recovery pipe 10 is installed on the top of the splash shield 1. The end of the negative pressure recovery pipe 10 facing away from the dust suction pipe 4 is connected to a fan or a vacuum cleaner. The bottom end of the dust suction pipe 4 extends to the inner cavity of the splash shield 1. The flying materials in the splash shield 1 are sucked and recovered by the dust suction pipe 4 and the negative pressure recovery pipe 10, thereby avoiding waste of raw materials.

[0029] The feed pipe 31 is installed in the reserved hole, and the top end thereof is connected to the centrifuge discharge pipe 9 through a flange 32 , so that the material can fall from the centrifuge discharge pipe 9 into the feed pipe 31 .

[0030] The bottom frame 6 is located below the splash shield 1, and a splash shield telescopic soft cover 5 is fixedly installed between the top of the bottom frame 6 and the bottom of the splash shield 1. The splash shield telescopic soft cover 5 can be extended or folded according to the height of the bottom frame 6. When extended, it can adapt to belt conveyors of different heights. When folded, it is convenient to clean and maintain the belt conveyor or the splash shield 1.

[0031] Two sealing strips 7 for contacting the front and rear frames of the belt conveyor are installed at the bottom of the bottom frame 6.

[0032] It also includes two electric push rods 2, which are installed on the top of the splash cover 1, one on the left and one on the right. The telescopic end of the electric push rod 2 passes through the splash cover 1 and is fixedly connected to the inner edge of the bottom frame 6. By controlling the synchronous extension of the two electric push rods 2, the bottom frame 6 is driven to move downward, and the two sealing strips 7 are respectively in contact with the front and rear frames of the belt conveyor. The material in the centrifuge discharge pipe 9 falls onto the belt conveyor through the feed pipe 31. Under the action of the splash cover 1 and the splash cover telescopic soft cover 5, the problems of material flying, scattering and leakage when the material falls are effectively avoided.

[0033] When used specifically, the centrifuge feeding and spraying recovery device of the utility model first connects the feed pipe 31 to the centrifuge feeding pipe 9 through the flange 32, and then installs and fixes the device;

[0034] Then, the two electric push rods 2 are controlled to extend synchronously, driving the bottom frame 6 to move downward, and making the two sealing strips 7 contact the front and rear frames of the belt conveyor respectively. Finally, the material in the centrifuge discharge pipe 9 falls onto the belt conveyor through the feed pipe 31. Under the action of the splash guard 1 and the splash guard telescopic soft cover 5, the problems of material flying, scattering and leakage when the material falls are effectively avoided. At the same time, the flying material is sucked and recovered by the dust suction pipe 4 and the negative pressure recovery pipe 10.

[0035] Embodiment 2:

[0036] On the basis of the first embodiment, Figure 1 and Figure 2 As shown, it also includes a dust curtain 8 located between the two sealing strips 7. The dust curtain 8 is fixedly installed at the left end of the bottom frame 6, and its bottom is in contact with the belt surface of the belt conveyor. Under the action of the dust curtain 8, flying materials are prevented from being discharged through the gap at the left end, so that the dust suction pipe 4 on the right can centrally suck and recover the flying materials.

[0037] Embodiment three:

[0038] On the basis of the first embodiment, Figure 2 As shown, it also includes a telescopic hose 34, and the upper and lower ends of the telescopic hose 34 are fixedly connected with fixing rings 33 respectively. The upper fixing ring 33 is fixedly connected to the bottom end of the feed pipe 31, and multiple connecting rods 35 are installed between the lower fixing ring 33 and the inner edge of the bottom frame 6. By setting the telescopic hose 34, the bottom frame 6 drives the telescopic hose 34 to extend while descending, thereby extending the circulation time of the material in the pipeline. On the one hand, it can reduce the flying of materials, and on the other hand, it can more accurately control the falling position of the materials, thereby reducing the waste and loss of materials.
