Description

Technical Field

[0001] This utility model relates to the technical field of lotus seed processing equipment, and in particular to a lotus seed peeling and dry-wet separation device. Background Technology

[0002] Lotus seeds are widely used due to their nutritional and medicinal value. Traditional lotus seed processing involves steps such as shelling, removing the skin, and removing the core.

[0003] In the peeling step, existing processing equipment washes off the skin on the surface of lotus seeds by high-pressure rinsing, and then conveys the peeled lotus seeds out through a conveyor. The process requires continuous high-pressure water rinsing, which causes serious water waste and increases processing costs. In addition, the rinsing water and lotus seed skins are usually discharged on-site or collected and discharged in a centralized manner. Since the lotus seed skins are extremely alkaline, the discharge will cause water pollution. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a lotus seed peeling and dry-wet separation device that separates the lotus seed peel from the water after high-pressure rinsing, while simultaneously collecting and recycling the rinsed water. This reduces processing costs, increases water utilization, and effectively avoids water pollution caused by direct discharge of rinsing water.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a lotus seed peeling and dry-wet separation device, including a peeling device, which is equipped with a peeling water gun and a conveying mechanism, and a dry-wet separation device, wherein the dry-wet separation device includes:

[0006] The water storage tank has a discharge port on one side of its surface;

[0007] The spiral extrusion rod is installed inside the water storage tank, with one end extending from the discharge port to the outside of the water storage tank and fixed.

[0008] The filter screen is installed inside the water storage tank along the extension direction of the spiral extrusion rod and located below the spiral extrusion rod, with one end of the filter screen set at the discharge port;

[0009] A water pump, with its inlet end connected to the inside of the water storage tank and its outlet end connected to the washing machine.

[0010] The garment removal device is located at the top of the water storage tank. After being rinsed by the garment removal water gun, the lotus leaves and washing water flow into the water storage tank. The washing water enters the water storage tank through the filter screen, while the lotus leaves are trapped inside the filter screen and squeezed out of the discharge port by the spiral extrusion rod.

[0011] Specifically, the garment removal device is provided in two units and arranged symmetrically. The garment removal device includes a housing with an open lower end. The garment removal water gun and the conveying mechanism are arranged inside the housing. The conveying mechanism includes a spiral conveying roller and a friction roller arranged side by side. A feeding channel is formed between the spiral conveying roller and the friction roller. The garment removal water gun is located above the feeding channel. The side surface of the housing is provided with a discharge port that communicates with one end of the feeding channel. A discharge hopper is provided at the lower end between the two discharge ports. The top of the housing is provided with a feed hopper that guides the garment to the starting end of the feeding channel.

[0012] Specifically, two pressure rods are arranged side by side above the feeding channel. The two pressure rods are parallel to the feeding channel and are located below the washing water gun.

[0013] Specifically, a rotatable feeding wheel is provided at the lower end of the feeding hopper, and the feeding wheel is located above the feeding channel.

[0014] Specifically, the garment removal device also includes a baffle plate, which is disposed inside the housing at the lower end of the spiral conveying roller and the friction roller, with the inner baffle plate inclined toward the upper end of the spiral extrusion rod.

[0015] Specifically, the clothes-removing water gun includes a water gun base and a plurality of water gun heads communicating with the lower part of the water gun base. The water gun base is provided with a water outlet hole communicating with the water gun heads.

[0016] Specifically, the water gun head can be installed in two ways: vertical installation and inclined installation, wherein the inclined water gun head is symmetrically arranged on both sides of the vertically installed water gun head.

[0017] Specifically, it also includes a humidity regulating device, which includes a limiting plate, a spring, and a spring limiting member that are sequentially connected and sleeved on the surface of the spiral extrusion rod located outside the discharge port, and can move along the surface of the spiral extrusion rod. The limiting plate has the same shape and size as the discharge port, and the surface of the spring limiting member is provided with an adjustment hole. The spring limiting member is fixed to the surface of the spiral extrusion rod by a connecting member passing through the adjustment hole.

[0018] Specifically, the dry-wet separation device also includes a liquid level sensing switch installed in the water storage tank, which is used to control the operation of the water pump based on the liquid level inside the water storage tank.

[0019] Specifically, several adjusting rods are provided on the outer surface of the water storage tank along the circumference of the discharge port. The ends of the adjusting rods are connected to flanges, and one end of the spiral extrusion rod is connected to the flange.

[0020] The beneficial effects of this utility model are as follows: After the lotus seeds are subjected to high-pressure washing and skin removal by the skin removal device, the washing water and lotus skin enter the dry and wet separation device. The water filter screen traps the lotus skin, and the washing water enters the water storage tank. Under the rotation and extrusion of the spiral extrusion rod, the lotus skin is separated out. At the same time, a water pump is installed in the water storage tank to collect the washing water for recycling and high-pressure washing and skin removal again, which reduces the processing cost, increases the water utilization rate, and effectively avoids the water pollution problem caused by direct discharge of washing water.

[0030] Figure label: Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figure 1 This embodiment discloses a lotus seed peeling and dry-wet separation device, including a peeling device 1 and a dry-wet separation device 2, with the peeling device 1 installed above the dry-wet separation device 2. The peeling device 1 includes a high-pressure water jet 11 for peeling the lotus seeds and a conveying mechanism for outputting the peeled lotus seeds. The dry-wet separation device 2 separates the washed lotus seed coat from the washing water, and simultaneously collects the washing water for recycling to perform high-pressure washing on the lotus seeds again.

[0033] Please see Figure 2-3 The dry-wet separation device 2 includes: a water storage tank 21, a spiral extrusion rod 22, a filter screen 23, and a water pump 24. The side surface of the water storage tank 21 is provided with a discharge port 211. The spiral extrusion rod 22 is installed inside the water storage tank 21, with one end extending from the discharge port 211 to the outside of the water storage tank 21. Several adjusting rods 212 are arranged on the outer surface of the water storage tank 21 along the circumference of the discharge port 211. The ends of the adjusting rods 212 are connected to flanges 213. One end of the spiral extrusion rod 22 is connected to the flanges 213 through bearings.

[0034] The filter screen 23 is installed inside the water storage tank 21 along the extension direction of the spiral extrusion rod 22 and is located below the spiral extrusion rod 22. One end of the filter screen 23 is set at the discharge port 211. In a preferred embodiment, the filter screen 23 is set as a cylinder and covers the spiral extrusion rod 22 to facilitate the centralized collection and discharge of lotus seed coats. The upper surface of the filter screen 23 has an opening along its extension, and inclined guide plates 231 are provided on both sides of the opening to facilitate the flow of lotus seed coats and washing water.

[0035] After being rinsed by the water gun, the lotus seed coat and the washing water flow to the water storage tank 21. The washing water enters the water storage tank 21 through the filter screen 23, while the lotus seed coat is trapped in the filter screen 23 and squeezed out of the discharge port 211 by the spiral extrusion rod 22, thus achieving dry and wet separation of the lotus seed coat and the washing water. The inlet of the water pump 24 is connected to the water storage tank 21, and the outlet is connected to the water gun 11. The water pump 24 recycles the washing water to rinse the lotus seeds again under high pressure.

[0036] As a preferred embodiment, the dry and wet separation device 2 also includes a liquid level sensing switch 25 installed in the water storage tank 21, which is used to control the operation of the water pump 24 according to the sensing liquid level inside the water storage tank 21. When the water level in the water storage tank 21 reaches the set value, the water pump 24 is controlled to recycle the cleaning water in the water storage tank 21 to perform high-pressure rinsing on the lotus seed coat again.

[0037] Please see Figure 4 The dry and wet separation device 2 also includes a humidity regulating device for adjusting the dryness and humidity of lotus seed coats. The humidity regulating device includes a limiting plate 26, a spring 27, and a spring limiting member 28 that are sequentially connected and sleeved on the surface of the spiral extrusion rod 22 located outside the discharge port 211, and can move along the surface of the spiral extrusion rod 22. The limiting plate 26 has the same shape and size as the discharge port 211. The surface of the spring limiting member 28 is provided with an adjustment hole 281, which is fixed to the surface of the spiral extrusion rod 22 by screws or other connecting parts passing through the adjustment hole 281.

[0038] The moisture content of the lotus seed coat can be controlled by adjusting the distance between the limiting plate 26 and the discharge port 211. The closer the limiting plate 26 is to the discharge port 211, the lower the moisture content of the lotus seed coat. Since the shape and size of the limiting plate 26 are the same as those of the discharge port 211, when the limiting plate 26 is just locked at the discharge port 211, the lotus seed coat is sent out towards the discharge port 211 under the action of the spiral extrusion rod 22. As more and more lotus seed coats accumulate, the water is discharged into the water storage tank 21 under the squeezing action. Finally, the squeezing force is greater than the elastic force of the spring 27, which pushes the limiting plate 26 open and discharges the lotus seed coat with lower water content from the discharge port 211. When the limiting plate 26 is far away from the discharge port 211, the lotus seed coat is discharged directly from the discharge port 211 with higher water content.

[0039] Please see Figure 5 The garment removal device 1 is provided in two units and arranged symmetrically. The garment removal device 1 includes a housing 12 with an open lower end, and a garment removal water gun 11 and a conveying mechanism are arranged inside the housing 12.

[0040] The conveying mechanism includes a spiral conveying roller 13 and a friction roller 14 arranged side by side, forming a feeding channel between the spiral conveying roller 13 and the friction roller 14. The washing gun 11 is located above the feeding channel. The side surface of the housing 12 is provided with a discharge port 121 that communicates with one end of the feeding channel (see reference). Figure 2 A discharge hopper 15 is provided at the lower end between the two discharge ports 121, and a feed hopper 16 is provided at the top of the shell 12 and guides it to the beginning of the feeding channel.

[0041] Please see Figure 6-7 The water gun 11 for removing clothes includes a water gun base 111 and several water gun heads 112 connected to the lower part of the water gun base 111. The water gun base 111 is provided with water outlet holes 113 that communicate with the water gun heads 112. The water outlet end of the water pump 24 is connected to the water outlet holes 113. Several water outlet holes 113 are provided. In addition to being connected to the water pump 24, they can also be connected to external high-pressure water. The water gun heads 112 can be installed vertically or at an angle. The water gun heads 112 installed at an angle are symmetrically arranged on both sides of the water gun heads 112 installed vertically and are inclined towards the direction of the water gun heads 112 installed vertically. The water gun heads 112 installed vertically can cut the clothes in the middle with high-pressure water, while the water gun heads 112 installed at an angle can cut the clothes in the side, thereby increasing the rate of clothes removal.

[0042] Lotus seeds awaiting peeling enter the feeding channel formed between the spiral conveyor roller 13 and the friction roller 14 from the feed hopper 16. The lotus seed particles move along the discharge port 121 under the rotation of the spiral conveyor roller 13 and the friction roller 14. During the movement, they are washed by the peeling water gun 11 and the spiral conveyor roller 13 and the friction roller 14 come into contact and rub against each other, which speeds up the peeling efficiency of the lotus seeds and cleans them in all directions, so that the lotus seed skin is quickly removed. After peeling, the lotus seeds are driven by the spiral conveyor roller 13 to the discharge port 121 and fall into the discharge hopper 15, where the peeled lotus seeds are collected.

[0043] In a preferred embodiment, a baffle plate 17 is provided inside the housing 12 at the lower end of the spiral conveying roller 13 and the friction roller 14. The baffle plate 17 is inclined toward the upper end of the spiral extrusion rod 22, and the washing water and lotus seed coat are concentrated and guided to the upper end of the spiral extrusion rod 22 through the baffle plate 17, which facilitates dry and wet separation.

[0044] In a preferred embodiment, two parallel pressing rods 18 are provided above the feeding channel. The two pressing rods 18 are parallel to the feeding channel and located below the peeling water gun 11. During the washing process, the pressing rods 18 prevent the lotus seeds from jumping up and down and falling off, and can stably sit on the spiral conveyor roller 13 and the friction roller 14, thereby improving the peeling efficiency of the lotus seeds.

[0045] In a preferred embodiment, a rotatable feeding wheel 19 is provided at the lower end of the feeding hopper 16, and the feeding wheel 19 is located above the feeding channel. The rotation of the feeding wheel 19 ensures that the lotus seeds enter evenly and stably, preventing them from clogging the feeding hopper 16.

[0046] Please see Figure 5 The power transmission structure of this embodiment is as follows: in the two garment removal devices 1, two spiral conveyor rollers 13 are connected, and two friction rollers 14 are connected. Specifically, one end of the spiral conveyor roller 13 and the friction roller 14 extends to the middle of the two garment removal devices 1 and is connected. A transmission wheel 3 is sleeved at the connection of the two friction rollers 14, and a conveyor belt is sleeved on the surface of the transmission wheel 3. Rotation is achieved by connecting an external drive device, that is, the spiral conveyor rollers 13 and friction rollers 14 of the garment removal devices on the left and right sides rotate simultaneously.

[0047] Please see Figure 8 As shown, the garment removal device 1 located on the right side of the figure has a spiral conveying roller 13, a friction roller 14, and a material-pushing wheel 19. One end of each of these components is fixed by a bearing and extends to the outside of the garment removal device housing 12, where a synchronous pulley 4 is connected. The synchronous pulleys 4 are connected by a synchronous belt 5. The friction roller 14 rotates under the drive of the drive device, which in turn drives the spiral conveying roller 13 and the material-pushing wheel 19 to rotate simultaneously via the synchronous belt 5.

[0048] Please see Figure 9 As shown, located Figure 5On the left side of the garment removal device 1, one end of the spiral conveyor roller 13, friction roller 14, and feeding wheel 19 is fixed by bearings and extends to the outside of the garment removal device housing 12 and is connected to a synchronous wheel 3; at the same time, one end of the spiral extrusion rod 22 in the dry and wet separation device 2 is also fixed by bearings and extends to the outside of the water storage tank 21 and is connected to a synchronous wheel 3; the synchronous wheel 3 between the spiral conveyor roller 13 and the feeding wheel 19 is connected by a synchronous belt 4, and the synchronous wheel 3 between the friction roller 14 and the spiral extrusion rod 22 is connected by a synchronous belt 4.

[0049] In this embodiment, the transmission method enables a single drive device to simultaneously drive the spiral conveyor roller 13, friction roller 14, feed wheel 19, and spiral extrusion rod 22, resulting in high efficiency. Of course, the left and right side garment removal devices and dry-wet separation devices can also be equipped with independent transmission methods according to actual needs.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
