Description

Technical Field

[0001] This utility model belongs to the field of agricultural substrate treatment technology, specifically relating to a salt washing device for coconut coir. Background Technology

[0002] Coconut coir, a byproduct of coconut processing, is widely used in horticulture and hydroponics due to its excellent air permeability and water retention. However, natural coconut coir contains high levels of salt, and direct use can lead to salt damage in plants, severely affecting their growth and development. Therefore, it must be washed and desalinated before use.

[0003] Traditional desalination methods involve soaking in large amounts of water and repeated dilution, resulting in high water consumption and low efficiency. To address these issues, existing patent CN214155692U discloses a spray-extrusion coconut coir desalination device. This device transports coconut coir via a belt conveyor, with a spray device above the conveyor for salt washing. Finally, a dewatering machine at the end of the conveyor chain centrally extrudes and dehydrates the sprayed coconut coir. This continuous operation mode of "one spray, one dewatering" represents an improvement in water conservation and efficiency compared to traditional soaking methods. However, in practical applications, it has been found that while the surface moisture of the coconut coir is washed away after spraying, the fibers still retain a large amount of highly saline water. This internal water cannot be fully and thoroughly removed by the single extrusion at the end. Consequently, the coconut coir retains a high residual salt content after passing through the entire device, resulting in an unsatisfactory desalination effect. To achieve the required standard, it may be necessary to reduce the conveying speed or perform secondary processing, which negatively impacts the overall efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary to design a salt washing device for coconut coir. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0020] like Figures 1 to 5 As shown, this embodiment provides a salt washing device for coconut coir, comprising: A belt conveyor 1 includes: a frame 11, two conveyor rollers 12 bearing-connected to the frame 11, and a belt filter conveyor belt 13 wound around the two conveyor rollers 12; a plurality of equidistantly arranged cleaning components 2, each including: a water pipe 21 disposed above the belt filter conveyor belt 13 and at least three nozzles 22 connected to the water pipe 21; wherein each nozzle 22 is adapted to rinse coconut coir on the belt filter conveyor belt 13; a plurality of equidistantly arranged extrusion components 3, spaced apart from each cleaning component 2, each including: an extrusion roller 31 disposed above the belt filter conveyor belt 13; wherein the extrusion roller 31 is adapted to extrude coconut coir on the belt filter conveyor belt 13 during rotation to dehydrate the coconut coir; wherein the belt conveyor 1 further includes: a reducer disposed on the frame 11 and a motor connected to the reducer; wherein the reducer is connected to any one of the conveyor rollers 12; and the motor is adapted to drive the current conveyor roller 12 to rotate via the reducer, the conveyor roller 12 being driven by the belt filter conveyor belt 13 to rotate. The filter conveyor belt 13 drives another conveyor roller 12 to rotate. The belt filter conveyor belt 13 carries coconut coir; during transport, its filtration characteristics allow water and light to pass through while simultaneously conveying the coconut coir, thus completing salt washing and dehydration. Spray nozzles 22 are used to wash the coconut coir on the belt filter conveyor belt 13, washing away the salt on the surface of the coconut coir with the sprayed water flow. Simultaneously, some water penetrates into the coconut coir fibers, dissolving some of the internal salt. Squeezing rollers 31 apply pressure to the coconut coir on the belt filter conveyor belt 13, squeezing out the adsorbed and saturated water in the coconut coir, achieving dehydration, reducing the moisture content of the coconut coir, and further removing some salt. The belt conveyor 1 enables continuous transport of the coconut coir. Combined with several equidistantly arranged washing components 2 and squeezing components 3, uninterrupted salt washing and dehydration of the coconut coir can be performed, improving production efficiency and suitable for large-scale coconut coir processing needs.

[0021] In this embodiment, by employing several equally spaced washing components 2 and extrusion components 3, with the two spaced apart, the coconut coir undergoes multiple washing and extrusion processes during transportation. Multiple washing processes allow more water to penetrate into the coconut coir fibers, dissolving more salt; multiple extrusion processes allow for more thorough removal of water and salt from the coconut coir, effectively reducing salt residue and greatly improving the desalination effect, making the treated coconut coir more suitable for plant growth.

The extrusion roller 31 is adapted to cooperate with the two second redirecting rollers 143 and the first redirecting roller 142 to extrude and dehydrate the coconut coir on the belt filter conveyor 13. By setting the redirection component 14, the running direction of the belt filter conveyor 13 is changed by the combined action of the first redirecting roller 142 and the two second redirecting rollers 143, so that the belt filter conveyor 13 forms a V-shaped structure, thereby ensuring the aggregation and stability of the coconut coir during the conveying process, and at the same time, it can better withstand the pressure of the extrusion roller 31 during extrusion and dehydration.

[0023] The extrusion assembly 3 further includes: two extrusion roller support frames 32 mounted on the frame 11 and a reduction motor 33 mounted on any one of the extrusion roller support frames 32; wherein the two extrusion roller support frames 32 are connected to the extrusion roller 31 bearings; the output shaft of the reduction motor 33 is connected to the extrusion roller 31; wherein by setting the reduction motor 33, it is ensured that the rotational speed of the extrusion roller 31 is matched with the rotational speed of the conveying roller 12, and the appropriate rotational speed ensures that the extrusion roller 31 applies uniform and stable pressure to the coconut coir, so that the extrusion is not insufficient due to excessive rotational speed, nor is the production efficiency affected by excessively slow rotational speed, thereby achieving precise control of the coconut coir dehydration process.

[0024] The cleaning assembly 2 further includes two water pipe support frames 23 disposed on the frame 11; wherein the water pipe support frames 23 are connected to the water pipes 21; wherein the water pipe support frames 23 are disposed to support the water pipes 21.

[0025] The belt conveyor 1 further includes: a plurality of equidistant idler rollers 15 and two tension rollers 16; wherein each idler roller 15 and the two tension rollers 16 are connected to the frame 11 bearings; each idler roller 15 and the two tension rollers 16 are adapted to contact the belt filter conveyor 13; and the two tension rollers 16 are disposed between the two conveyor rollers 12; each idler roller 15 is disposed between the two tension rollers 16; wherein the idler rollers 15 are provided to provide stable support for the belt filter conveyor 13, preventing the belt filter conveyor 13 from excessively sagging due to the weight of the brine, and the idler rollers 15 are connected to the frame 11 bearings, and the rotation of the idler rollers 15 reduces the friction between the belt filter conveyor 13 and the idler rollers 15; wherein the tension rollers 16 are provided to tension the belt filter conveyor 13, ensuring sufficient friction between the belt filter conveyor 13 and the conveyor rollers 12, so that the belt filter conveyor 13 can transmit power normally and avoid slippage.

[0026] The belt conveyor 1 has a feed chute 4 at its first conveying end and a discharge chute 5 at its last conveying end. The feed chute 4 has a support 6 at its bottom.
