Description

Technical Field

[0001] The utility model relates to the technical field of chemical safety, in particular to a powdered salt screening device. Background Art

[0002] In the prior art, powdered salt devices are widely used in salt processing lines. These devices generally rely on screw feeders to evenly transport powdered salt to different parts of the production line.

[0003] However, in actual production, powdered salt is susceptible to caking during storage and transportation due to factors such as humidity and temperature fluctuations. This clumping can cause the screw feeder to become clogged or stuck when entering the feed port, compromising the device's ability to continuously feed the salt. Furthermore, uneven feeding of the powdered salt device affects the uniformity of the salt content, which in turn negatively impacts the stability of the crude brine, reducing product quality and potentially lowering production efficiency.

[0004] In summary, there is an urgent need for a powder salt screening device that can reduce the occurrence of spiral jams during the feeding process, ensure uniform feeding, and control the salt content. Utility Model Content

[0005] The purpose of the invention of the utility model is to provide a powder salt screening device to solve the problems existing in the prior art, which can reduce the situation of spiral jamming during the feeding process, make the feeding uniform, and control the salt content.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A powder salt screening device comprises a feeding port, wherein a screening device is provided on the feeding port, the screening device is a mesh screen structure, and is detachably connected to the feeding port, and is used for separating large and small salt blocks.

[0008] Preferably, the screening device comprises a first screening mesh screen and a second screening mesh screen, and the first screening mesh screen and the second screening mesh screen are arranged at an angle.

[0009] Preferably, the angle between the first screening mesh and the second screening mesh is 30° to 45°.

[0010] Preferably, the mesh pore size of the first screening mesh and the second screening mesh is 140*190mm to 160*210mm.

[0011] Preferably, the first screening mesh screen and the second screening mesh screen are fixedly connected.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] The present application adds a screening device to the powder salt feeding port, wherein the screening device includes a first screening mesh screen and a second screening mesh screen. When in use, the powder salt is loaded above the feeding port by a loader. Due to the provision of the screening device, small pieces of powder salt can pass through the screening device and enter the hopper, while agglomerated powder salt with larger particle sizes is blocked by the screening device. This can ensure that the powder salt entering the spiral feeder through the feeding port will not be blocked or stopped due to the large particle size. At the same time, it can extend the service life of the equipment, ensure uniform feeding, and control the salt content.

[0014] The first screening mesh and the second screening mesh of the present application are set at a certain angle. When in use, large pieces of powdered salt will slide through the first screening mesh and the second screening mesh to a fixed position and can be collected for subsequent further processing.

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Example 1

[0021] A powder salt screening device, such as Figure 1 and Figure 2 As shown, it includes a feeding port 1, and a screening device 2 is provided on the feeding port 1. The screening device 2 is a mesh screen structure, which is detachably connected to the feeding port 1. The screening device 2 is used to separate large and small salt blocks. When loading salt, the powdered salt is usually loaded onto the feeding port 1 by a loader. The screening device 2 is snap-fitted or threadedly connected to the feeding port 1. Only small pieces of powdered salt can pass through the screening device 2 and enter the silo, while the agglomerated powdered salt with larger particle size is blocked by the screening device 2 and slides to a fixed position for collection. This ensures that the powdered salt entering the screw feeder through the feeding port will not be blocked due to its large particle size. At the same time, it can extend the service life of the equipment, ensure uniform loading, and control the salt content.

[0022] Specifically, the screening device 2 includes a first screening mesh 21 and a second screening mesh 22, and the first screening mesh 21 and the second screening mesh 22 are arranged at an angle. The angle between the first screening mesh 21 and the second screening mesh 22 is 30° to 45°. Preferably, the angle can be set to 45°. When in use, there is a certain angle between the first screening mesh 21 and the second screening mesh 22, which is conducive to the sliding of large pieces of salt blocks, so that small pieces of powdered salt can smoothly enter the silo. Furthermore, a collection device can be set on both sides of the first screening mesh 21 and the second screening mesh 22 to collect large pieces of powdered salt for subsequent processing.

[0023] Specifically, the mesh pore size of the first screening mesh 21 and the second screening mesh 22 is 140*190mm to 160*210mm. Preferably, the mesh pore size can be set to 150*200mm, and can be set to a square grid or a diamond grid, etc., as long as it can achieve the purpose of screening out large pieces of powdered salt.

[0024] Specifically, the first screening mesh 21 and the second screening mesh 22 are fixedly connected. When in use, they can further withstand a certain gravity and have a long service life.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
