Description

Technical Field

[0001] The invention relates to the technical field of distiller's grains squeezing equipment, and in particular to a distiller's grains feed squeezing and processing device. Background Art

[0002] Wine lees are byproducts of the winemaking process. They are rich in protein, vitamins and minerals and are a potential high-quality feed resource. Different types of wine lees, such as beer lees, white wine lees and grape wine lees, contain different proportions of nutrients and are suitable for development and utilization as feed.

[0003] In the process of preparing distiller's grains into feed, the distiller's grains need to be dehydrated. The existing distiller's grains dehydration treatment mostly adopts heating and drying treatment. The drying and dehydration process consumes a lot of heat energy, which increases the treatment cost; the investment in drying equipment is large and the operating cost is high, including equipment purchase fee, maintenance fee, energy consumption fee, etc.; the waste gas, wastewater and other pollutants generated in the drying process may have a certain impact on the environment, and corresponding environmental protection measures need to be taken to deal with them. Summary of the invention

[0004] The purpose of the present invention is to provide a device for squeezing and processing distiller's grains feed, which can reciprocately squeeze distiller's grains and has a good squeezing and dehydrating effect.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A device for squeezing and processing distiller's grains feed comprises a support plate for placing distiller's grains to be squeezed, an extrusion device for squeezing the distiller's grains in the support plate is arranged above the support plate, the extrusion device comprises an extrusion plate arranged at the bottom of the extrusion device for direct contact with the distiller's grains in the support plate during the squeezing process, a plurality of through holes are arranged on the extrusion plate, the top surface height of the extrusion plate gradually increases from the center to the surrounding direction, a filter screen for liquid to pass through is arranged in the central area of ​​the extrusion plate, and a drainage port corresponding to the area where the filter screen is located is arranged in the central area of ​​the support plate. Both the support plate and the extrusion plate are conical in shape, the support plate is coaxially arranged with the extrusion plate, and the extrusion device drives the extrusion plate to move in the axial direction of the extrusion plate. The through holes are evenly distributed in a circular array on the extrusion plate. Its function is that, through the arrangement of the through holes on the extrusion plate, when the extrusion plate squeezes the lees on the top surface of the support plate from top to bottom, the squeezed liquid flows into the top surface of the extrusion plate through the through holes, and the liquid flowing to the top surface of the extrusion plate cannot flow back to the support plate in the end. At the same time, through the design of the shape of the extrusion plate and the position of the filter screen, the liquid flows out from the filter screen located at the lowest point on the extrusion plate, most of the lees are retained between the support plate and the extrusion plate, and a small part of the lees entering the top surface of the extrusion plate is also blocked by the filter screen and remains on the top surface of the extrusion plate. The extrusion device reciprocates up and down for many times, so that the lees are subjected to multiple reciprocating extrusions, and the squeezing effect is good.

[0007] Furthermore, the thickness of the squeeze disk is uniform, the shape of the top surface of the support disk is the same as the shape of the bottom surface of the squeeze disk, a baffle ring is arranged vertically to the top surface of the support disk on the top surface of the central area of ​​the support disk, and the hollow area of ​​the baffle ring is the drain port. The baffle ring is arranged coaxially with the squeeze disk. Its function is to prevent the lees from falling directly into the drain port and being discharged through the setting of the baffle ring.

[0008] Furthermore, a drainage ring is provided on the top surface of the central area of ​​the extrusion disk, which is coaxially arranged with the retaining ring; an embedding groove for embedding the retaining ring is provided on the bottom surface of the drainage ring; a filter screen is provided on the drainage ring and surrounds the wall surface outside the embedding groove; a liquid outlet corresponding to the filter screen is provided on the drainage ring and surrounds the embedding groove; a liquid guide tube is provided on the bottom surface of the extrusion disk, which is coaxially arranged with the drainage ring; the outer diameter of the liquid guide tube is equal to the inner diameter of the embedding groove and equal to the inner diameter of the retaining ring. The length of the liquid guide tube is greater than the maximum moving distance of the extrusion disk during the reciprocating squeezing process, which can prevent the liquid guide tube from moving out of the retaining ring and causing a slight translation and being difficult to insert back into the retaining ring. Its function is that, through the setting of the embedding groove, the retaining ring can be prevented from blocking the contact between the extrusion disk and the support disk; through the setting of the filter screen and the liquid outlet, when the retaining ring is moved out of the embedding groove, the liquid on the top surface of the extrusion disk can be discharged through the filter screen, the embedding groove, and the liquid outlet in sequence into the liquid guide tube.

[0009] Furthermore, when the extrusion plate is in close contact with the support plate, the top height of the retaining ring is higher than the top height of the filter screen, and the bottom height of the liquid outlet is lower than the bottom height of the filter screen. The height of the bottom of the filter screen is not higher than the height of the lowest point of the bottom surface of the extrusion plate. Its function is that, through the design of the positional relationship between the retaining ring and the filter screen, the retaining ring can completely pass through the height of the filter screen, which can play a certain cleaning role on the filter screen and push out the wine lees stuck on the filter screen; through the design of the positional relationship between the liquid outlet and the filter screen, the liquid passing through the filter screen can all pass through the liquid outlet.

The hydraulic cylinder with the telescopic rod itself is a common prior art and is not described in detail. Its function is to drive the squeezing plate to move toward the support plate through the arrangement of the hydraulic cylinder and the telescopic rod.

[0011] Furthermore, the distiller's grains feed pressing and processing device further comprises a collar sleeved at the connection between the telescopic rod and the drainage ring, the telescopic rod comprises an embedded portion embedded in the drainage ring, and the distiller's grains feed pressing and processing device further comprises fasteners that simultaneously penetrate the collar, the drainage ring and the embedded portion on opposite sides of the whole, the fasteners are screws or pins. The fasteners are located above the embedded groove and are separated from the embedded groove. The function is that the connection between the telescopic rod and the drainage ring can be realized through the arrangement of the embedded portion and the fasteners; the distiller's grains or liquid can be prevented from entering the connection between the telescopic rod and the drainage ring through the arrangement of the collar.

[0012] Furthermore, a bearing sleeved on the outer wall of the telescopic rod is provided on the top surface of the collar, the inner wall of the upper shell is cylindrical, the telescopic rod is provided on the axis of the upper shell, a spiral channel coaxially arranged with the upper shell is provided inside the upper shell, the spiral channel opens toward the axis direction of the upper shell, a connecting rod is provided between the spiral channel and the bearing, the connecting rod is fixedly connected to the bearing, a liquid absorbing member is sleeved on the outer surface of the connecting rod, and the bottom end of the liquid absorbing member contacts the top surface of the extrusion plate. The liquid absorbing member is made of a flexible material with a certain liquid absorbing capacity, such as cotton cloth. Its function is that, through the arrangement of the bearing, the connecting rod, the spiral channel and the liquid absorbing member, the hydraulic cylinder can drive the extrusion plate to move up and down while the liquid absorbing member spirally rises or spirally descends, so that the liquid absorbing member can sweep the entire top surface of the extrusion plate, and sweep the lees on the top surface of the extrusion plate back to the support plate through the through hole, and at the same time, the liquid absorbed by the liquid absorbing member gathers to the lowest point of the liquid absorbing member due to gravity and drips to the discharge port.

[0013] Furthermore, a roller located in the spiral channel is provided at one end of the connecting rod away from the bearing, and the height difference between the top and the bottom of the roller is smaller than the width of the spiral channel. The function of the roller is to reduce the friction between the connecting rod and the spiral channel through the setting of the roller, so that the connecting rod can spirally rise or spirally descend.

[0014] Furthermore, the support plate is provided with a protrusion corresponding to the through hole, and the outer diameter of the protrusion is less than or equal to the outer diameter of the through hole. Its function is that the wine lees stuck in the through hole can be pushed out by the setting of the protrusion.

[0015] Furthermore, the protrusion is spherical, the thickness of the support plate is smaller than the outer diameter of the protrusion, the center of the protrusion is located inside the support plate, a support body is provided below the support plate, a groove for embedding the protrusion is provided on the top surface of the support body, and a liquid guide channel for the liquid guide tube to enter is provided in the central area of ​​the support body. Its function is that, through the arrangement of the support body and the support plate, it can support the pressure of the support plate, and at the same time, after the squeezing is completed, the upper shell and the support plate can be removed, so as to facilitate the pouring of the wine lees; through the arrangement of the groove, it can prevent the support plate from rotating on the top surface of the support body, so that the protrusion can smoothly enter the through hole.

[0016] The present invention has the beneficial effects:

[0017] 1. Through the arrangement of the through holes on the extrusion plate, when the extrusion plate squeezes the lees on the top surface of the support plate from top to bottom, the squeezed liquid flows into the top surface of the extrusion plate through the through holes, and the liquid flowing to the top surface of the extrusion plate cannot flow back to the support plate. At the same time, through the design of the shape of the extrusion plate and the position of the filter screen, the liquid flows out from the filter screen located at the lowest point of the extrusion plate, and most of the lees are left between the support plate and the extrusion plate. A small part of the lees entering the top surface of the extrusion plate is also blocked by the filter screen and remains on the top surface of the extrusion plate. The extrusion device reciprocates up and down for many times, so that the lees are repeatedly squeezed, and the squeezing effect is good;

[0018] 2. The setting of the baffle ring can prevent the lees from falling directly into the discharge port;
