Description

Technical Field

[0001] This invention relates to the field of distiller's grains fertilizer, and more specifically to a distiller's grains dehydration processing apparatus. Background Technology

[0002] Distillers' grains have a crude protein content of about 25%. Because they contain a lot of beneficial substances, they can be processed into feed or fertilizer through different methods.

[0003] When producing distillers' grains fertilizer, the high moisture content of the distillers' grains needs to be dehydrated first. Current distillers' grains dehydration equipment is generally a mechanical extrusion dehydration structure, which can dehydrate a certain amount of distillers' grains at a time, and cannot perform continuous dehydration. The dehydration efficiency is low. In addition, depending on the production requirements of different distillers' grains feed and the different types of distillers' grains, different degrees of dehydration are required. However, the current dehydration equipment can only complete the dehydration treatment of a single standard, which cannot meet the current requirements. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a dehydration processing device for distiller's grains, including an extrusion box with a plurality of dehydration holes on its side wall, a conveyor installed on one side of the extrusion box, the conveyor being used to continuously feed material into the extrusion box, a discharge channel for discharging material is provided on the side of the extrusion box opposite to the conveyor, the discharge channel being connected to the inner cavity of the extrusion box, the discharge channel being a spiral channel, the pitch of the discharge channel increasing along the direction away from the extrusion box.

[0005] The above technical solution enables the continuous feeding of water-containing distiller's grains into the extrusion chamber and into the discharge channel. As more material enters the extrusion chamber, and because the discharge channel is spiral-shaped with its pitch increasing away from the extrusion chamber, the amount of material discharged along the discharge channel is less than the amount of material fed into the extrusion chamber by the conveyor. This results in an increase in pressure within the extrusion chamber. As the pressure increases, water is squeezed out and discharged from the dewatering holes on the side wall of the extrusion chamber, achieving continuous extrusion dewatering with high efficiency.

[0006] Preferably, the diameter of the discharge channel gradually decreases along its spiral direction.

[0007] The above technical solution achieves the following: as the discharge channel diameter decreases, the pressure on the material increases, which in turn increases the extrusion pressure on the material in the extrusion box, thereby improving the dehydration effect.

[0008] Preferably, the inner wall of the extrusion chamber is provided with a feed inlet that communicates with the discharge channel, and the side wall of the extrusion chamber where the feed inlet is located is provided with an inclined surface, which is used to guide the material in the inner cavity of the extrusion chamber to the feed inlet.

[0009] The above technical solution makes it easier for materials in the extrusion box to enter the feed inlet, avoids material accumulation in the extrusion box, and ensures smooth material flow.

[0010] Preferably, the discharge channel is provided with a discharge port at the end away from the extrusion box, and a baffle is provided at the discharge port to block the material from being discharged. The baffle is connected to an adjustment device, which is used to adjust the pressure of the baffle blocking the material from being discharged.

[0011] The above technical solution enables the adjustment of the pressure of the baffle blocking the material discharge, and the adjustment of the pressure inside the extrusion chamber, thereby adjusting the pressure of extrusion and dehydration. This allows for the selection of different pressures for dehydration based on different types of distiller's grains, resulting in distiller's grains with different moisture contents.

[0012] Preferably, the adjusting device includes a rotating shaft and an adjusting mechanism. The rotating shaft is arranged on the upper side of the discharge port, and the axial direction of the rotating shaft is consistent with the diameter direction of the discharge port. A baffle is rotatably mounted on the rotating shaft, and the baffle is arranged outside the discharge port and covers the discharge port. The adjusting mechanism is used to adjust the pressure applied to the baffle.

[0013] The above technical solution enables the baffle to be rotated and installed, resulting in a stable structure and easy adjustment of the pressure applied to the baffle.

[0014] Preferably, the adjusting mechanism includes a stop member, one end of which is fixedly connected to a baffle, and the other end of which abuts against an elastic component. The elastic component is used to apply a spring force to the stop member to drive the baffle closer to the discharge port. The elastic component is connected to an adjusting component, which is used to adjust the spring force of the elastic component.

[0015] The above technical solution enables the adjustment of discharge pressure and dewatering pressure by adjusting the elastic force of the elastic component, which is convenient and reliable.

[0016] Preferably, the elastic component includes a rod and a spring. The rod is fixedly installed, and the rod and the abutment are distributed in a cross pattern. The spring is sleeved on the rod, with one end of the spring abutting against the abutment at the end away from the baffle. The other end of the spring is connected to an adjustment component, which is used to adjust the degree of spring compression.

[0017] The above technical solution achieves the goal of adjusting the discharge pressure and dewatering pressure by adjusting the compression degree of the spring, making it convenient and easy to adjust.

[0018] Preferably, the adjustment assembly includes an adjustment member and an adjustment unit. The adjustment member is sleeved on the rod, and the adjustment member and one end of the spring abutment are abutted together. The adjustment unit is used to adjust the movement of the adjustment member along the length of the rod.

[0019] The above technical solution achieves the purpose of adjusting the compression of the spring.

[0020] Preferably, the adjusting unit is a lead screw and nut mechanism, in which the length direction of the lead screw is consistent with the length direction of the rod, and the nut and adjusting component are fixedly connected.

[0021] The above technical solution enables adjustment via a lead screw and nut, facilitating control, providing accurate pressure regulation, and ensuring stable and reliable adjustment.

[0022] Preferably, the feeder includes a barrel, one end of which is closed and the other end is connected to the extrusion box. A feed screw is installed inside the barrel. The end of the feed screw away from the extrusion box is connected to the drive unit. A feed hopper is provided above the side of the barrel away from the extrusion box.

[0023] The above technical solution achieves continuous material feeding, with strong feeding capacity, enabling continuous delivery of materials into the extrusion chamber.

[0024] Preferably, the barrel body has several water outlet holes.

[0025] The above technical solution enables the drainage function of distiller's grains with high water content during the conveying process.

[0026] Preferably, a water tank is provided on the lower side of the material cylinder body and the extrusion box, with an opening at the top of the water tank covering the material cylinder and the extrusion box. The water tank is used to collect water discharged from the material cylinder and the extrusion box.

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0038] refer to Figure 1 and Figure 7 In this embodiment, a dehydration processing device for distiller's grains is proposed, including an extrusion box 100 with a plurality of dehydration holes 110 on its side wall. A conveyor 400 is installed on one side of the extrusion box 100. The conveyor 400 is used to continuously feed material into the extrusion box 100. A discharge channel 200 for discharging material is provided on the side of the extrusion box 100 opposite to the conveyor 400. The discharge channel 200 is connected to the inner cavity of the extrusion box 100. The discharge channel 200 is a spiral channel, and the pitch of the discharge channel 200 increases along the direction away from the extrusion box 100.

[0039] The commonly used dehydration method involves collecting a certain amount of distiller's grains in a hopper, then squeezing out the water through mechanical extrusion, and finally pouring out the dehydrated distiller's grains. This method has very low dehydration efficiency. The distiller's grains dehydration processing device proposed in this invention, through the setting of the conveyor 400, can continuously feed the distiller's grains containing water into the extrusion chamber 100. As the distiller's grains continuously enter the extrusion chamber 100, they are squeezed into the discharge channel 200. As more and more distiller's grains enter the extrusion chamber 100, they also continuously enter the discharge channel 200. In the material channel 200, and because the discharge channel 200 is spiral and its pitch increases in the direction away from the extrusion box, the lees can not only be squeezed into the discharge channel 200, but the discharge channel 200 also obstructs the flow of the lees. As the material flows along the discharge channel 200, its discharge volume will be less than the amount of material fed into the extrusion box 100 by the conveyor 400. This will cause the pressure inside the extrusion box 100 to increase. As the pressure increases, water is squeezed out and discharged from the dewatering holes on the side wall of the extrusion box 100, realizing continuous extrusion dewatering treatment with high dewatering efficiency.

[0040] refer to Figure 8 The diameter of the discharge channel 200 gradually decreases along its spiral direction, so that when the material flows in the discharge channel 200, as the diameter of the discharge channel 200 decreases, the resistance of the material increases, which further increases the extrusion pressure on the material in the extrusion box 100, thereby improving the dewatering effect.

[0041] refer to Figure 5 The inner wall of the extrusion chamber 100 is provided with an inlet 120 that communicates with the discharge channel 200. The side wall of the extrusion chamber 100 where the inlet 120 is located is provided with an inclined surface 130. The inclined surface 130 is used to guide the material in the inner cavity of the extrusion chamber 100 to the inlet 120. The lees are continuously fed into the inner cavity of the extrusion chamber 100 by the conveyor 400. In order to avoid the lees from accumulating in the extrusion chamber 100, the inclined surface 130 can guide the lees to the inlet, making it easier for the material in the extrusion chamber 100 to enter the inlet, avoiding the accumulation of material in the extrusion chamber 100, ensuring the smooth flow of material, and realizing continuous dehydration processing.

[0042] refer to Figure 3 and Figure 6The discharge channel 200 has a discharge port 210 at the end away from the extrusion box 100. A baffle 700 is installed at the discharge port 210 to block the material from being discharged. The baffle 700 is connected to an adjustment device 300, which is used to adjust the pressure of the baffle 700 blocking the material from being discharged. This allows for the adjustment of the pressure inside the extrusion box 100 by adjusting the pressure of the baffle 700 blocking the material from being discharged, thereby adjusting the pressure of the extrusion and dehydration. Different pressures can be selected for dehydration according to different types of distiller's grains, resulting in distiller's grains with different moisture contents. This meets a variety of different dehydration requirements and has wide applicability.

[0043] refer to Figure 6 The adjusting device 300 includes a rotating shaft 310 and an adjusting mechanism. The rotating shaft 310 is arranged on the upper side of the discharge port 210, and the axial direction of the rotating shaft 310 is consistent with the diameter direction of the discharge port 210. The baffle 700 is rotatably mounted on the rotating shaft 310 and is arranged outside the discharge port 210 and covers the discharge port 210. The adjusting mechanism is used to adjust the pressure applied to the baffle 700. The rotating installation of the baffle is realized, the structure is stable, and it is convenient to adjust the pressure applied to the baffle.

[0044] refer to Figure 6 The adjusting mechanism includes a stop member 320, one end of which is fixedly connected to a baffle 700, and the other end of which abuts against an elastic component. The elastic component applies a spring force to the stop member 320 to drive the baffle 700 closer to the discharge port 210. The elastic component is connected to an adjusting component, which is used to adjust the spring force of the elastic component. This allows for the adjustment of the discharge pressure and dewatering pressure by adjusting the spring force of the elastic component, making the adjustment convenient and reliable.

[0045] refer to Figure 6 The elastic component includes a rod 330 and a spring 340. The rod 330 is fixedly installed, and the rod 330 and the abutment 320 are distributed in a cross pattern. The spring 340 is sleeved on the rod 330, with one end of the spring 340 abutting against the abutment 320 at the end away from the baffle. The other end of the spring 340 is connected to an adjustment component, which is used to adjust the compression degree of the spring 340. This achieves the purpose of adjusting the discharge pressure and dewatering pressure by adjusting the compression degree of the spring, making it convenient and easy to adjust.

[0046] refer to Figure 6 The adjustment assembly includes an adjustment member 350 and an adjustment unit. The adjustment member 350 is sleeved on the rod 330. The adjustment member 350 and the end of the spring 340 away from the abutment member 320 abut against each other. The adjustment unit is used to adjust the movement of the adjustment member 350 along the length direction of the rod 330, thereby achieving the purpose of adjusting the compression of the spring.

[0047] The adjustment unit is a lead screw and nut mechanism. The length direction of the lead screw in the lead screw and the length direction of the rod are consistent. The nut and the adjustment component in the lead screw and nut mechanism are fixedly connected. This enables adjustment through the lead screw and nut, which is convenient for control, provides relatively accurate pressure adjustment, and ensures stable and reliable adjustment.

[0048] refer to Figure 2 The conveyor 400 includes a barrel 410, one end of which is closed and the other end is connected to the extrusion box 100. The barrel 410 is equipped with a conveying screw 420. The end of the conveying screw 420 away from the extrusion box 100 is connected to the drive unit 430. A feed hopper 500 is provided above the side of the barrel 410 away from the extrusion box 100. It realizes the function of continuous material conveying, has strong material conveying capacity, and can continuously transport materials into the extrusion box 100.

[0049] refer to Figure 1 and Figure 2 The material cylinder 410 has several water outlet holes 411 on its body; this enables the material with a high water content to be drained during the conveying process.

[0050] refer to Figure 1 A water tank is provided on the lower side of the material cylinder and the extrusion box. The water tank has an opening at the top, which covers the material cylinder and the extrusion box. The water tank is used to collect the water discharged from the material cylinder and the extrusion box. A baffle is provided on one side of the water tank to prevent the material discharged from the discharge channel outlet from falling into the water tank.

[0051] In the dehydration process of distiller's grains, the present invention involves manually or via conveyor belt transporting the water-containing distiller's grains to the feed hopper 500 at one end of the feed cylinder 410. The distiller's grains fall into the feed cylinder 410, and as the feed screw 420 inside rotates continuously, the distiller's grains are discharged into the extrusion chamber 100. During this process, the water outlet 411 on the lower end of the feed cylinder 410 allows for drainage of the distiller's grains, with water falling into the water tank 600 located below the feed cylinder 410. The distiller's grains are then discharged into the extrusion chamber 100, and guided by the inclined surface 130, they smoothly enter the feed inlet 120 and then the discharge channel 200. The discharge channel 200 increases the resistance to the flow of the distiller's grains, and the discharge outlet 200 further enhances this effect. The baffle 700 in section 10 obstructs the discharge of material, increasing the resistance to the lees and slowing down the discharge speed. This causes the lees to accumulate in the extrusion chamber 100, increasing the extrusion pressure on the lees and enabling them to be squeezed and dehydrated. As the pressure inside the extrusion chamber 100 increases, the pressure of the lees squeezed out of the discharge channel 200 also increases until the baffle 700 is pushed open and the lees are discharged. This process is continuous, achieving continuous dehydration. The resistance applied to the baffle to obstruct the discharge of lees is adjusted by adjusting the degree of compression of the adjusting element 350 and the spring 340 through the screw and nut mechanism, thus realizing the pressure adjustment function and the function of adjusting according to different dehydration requirements.

[0052] The invention features a stable mechanism, a reasonable layout, and stable operation, enabling continuous dehydration of distiller's grains with high dehydration efficiency. It also allows for adjustable dehydration pressure and is suitable for dehydration of different types of distiller's grains with varying moisture content requirements.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
