Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a high-efficiency filter press. Background Technology

[0002] In the brewing process, the filter press is the core equipment for solid-liquid separation. It is mainly used in key stages such as dehydration of distiller's grains, clarification and filtration of fermented mash, and refining of the wine. Its separation efficiency and quality directly affect the continuity of brewing production, the quality of finished wine, and the comprehensive utilization value of by-products (such as distiller's grains as feed).

[0003] Most current filter presses use hydraulic pressure to drive a pressure plate to squeeze the distiller's grains inside the filter cylinder to achieve filtration. However, such filter presses still have the following problems in actual use:

[0004] Current filter press equipment can only discharge water through the filter holes on the outside of the filter cylinder. If the diameter of the lees pile is large, the water in the center will have to travel a long distance to be discharged, which will affect the efficiency of water discharge in the center. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency filter press, which effectively solves the deficiencies of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a high-efficiency filter press, including a support base. A water receiving trough is fixedly connected to the top of the support base. A filter press cylinder is fixedly connected to the center of the top of the water receiving trough. One end of the filter press cylinder's opening extends through one side of the outer wall of the water receiving trough. A guide frame is fixedly connected to the support base near the opening of the filter press cylinder. A discharge port is opened at the center of the guide frame. A blocking gate is slidably connected to the inner wall of the guide frame. A hydraulic cylinder is fixedly connected to the center of the top of the side of the support base away from the guide frame. The telescopic end of the hydraulic cylinder extends through the center of the interior of the filter press cylinder and is fixedly connected to a pressure plate.

[0008] The technical effect achieved by adopting the above solution is that the pressure plate can be retracted to the outside of the feeding hopper to prevent obstruction of the addition of the lees.

[0009] Preferably, in any of the above embodiments, the extendable length of the hydraulic cylinder extension end is greater than the length of the filter press cylinder, the diameter of the pressure plate is adapted to the diameter of the inner wall of the filter press cylinder, the surface of the pressure plate is provided with several water outlet holes, and a drain pipe is fixedly connected to the center of the bottom surface of the water receiving tank.

The diameter of the corresponding discharge port and the diameter of the discharge port are both adapted to the diameter of the inner wall of the filter press cylinder, and the vertical height of the blocking gate is greater than twice the diameter of the filter press cylinder.

[0012] The technical effect achieved by adopting the above solution is that by using this solution, the direction of the blocking gate can be reversed, so that the blocking gate can be pressed tightly against the outlet of the filter cylinder, which can effectively block the lees.

[0013] Preferably, in any of the above embodiments, a support frame is fixedly connected to the top of the guide frame, an electric push rod is fixedly connected to the center of the top surface of the support frame, the telescopic end of the electric push rod is fixedly connected to the center of the top surface of the blocking gate, the height of the support frame is greater than the diameter of the filter press cylinder, and the corresponding discharge port is aligned with the inner wall of the filter press cylinder after the blocking gate is pulled to the top.

[0014] The technical effect achieved by adopting the above solution is that the top of the support frame can have sufficient lifting space.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 3 As shown, a high-efficiency filter press includes a support base 1. A water receiving tank 2 is fixedly connected to the top of the support base 1. A filter press cylinder 3 is fixedly connected to the center of the top of the water receiving tank 2. One open end of the filter press cylinder 3 extends through one side of the outer wall of the water receiving tank 2. A guide frame 6 is fixedly connected to the side of the support base 1 near the open end of the filter press cylinder 3. A discharge port 10 is opened at the center of the guide frame 6. A blocking gate 9 is slidably connected to the inner wall of the guide frame 6. A hydraulic cylinder 5 is fixedly connected to the center of the top of the side of the support base 1 away from the guide frame 6. The telescopic end of the hydraulic cylinder 5 extends through the center of the interior of the filter press cylinder 3 and is fixedly connected. There is a pressure plate 14, which is welded and fixed to the telescopic end of the hydraulic cylinder 5 by full welding. Several filter tubes 12 are fixedly connected to one side of the inner wall of the filter cylinder 3. Several filter holes are opened on the side of the filter tubes 12. Several through holes are opened on the surface of the pressure plate 14. Several through holes are slidably connected to several filter tubes 12 respectively. The purpose of the slidable connection is to ensure that water can be discharged quickly through the filter tubes without creating obstruction. The diameter of the through hole is adapted to the diameter of the outer wall of the filter tube 12. A feeding hopper 4 is fixedly connected to the edge of one side of the top of the filter cylinder 3. The feeding hopper 4 is connected to the interior of the filter cylinder 3.

[0024] As an optional technical solution of this utility model, the length of several filter tubes 12 is adapted to the length of the filter cylinder 3. Several filter tubes 12 are evenly distributed inside the filter cylinder 3 in a ring array. The distance between one side of the feeding hopper 4 and one side of the inner wall of the filter cylinder 3 is greater than the thickness of the pressure plate 14, so that the pressure plate 14 can be stored outside the feeding hopper 4 to prevent obstruction of the addition of the lees.

[0025] As an optional technical solution of this utility model, the telescopic length of the hydraulic cylinder 5 is greater than the length of the filter press cylinder 3, the diameter of the pressure plate 14 is adapted to the diameter of the inner wall of the filter press cylinder 3, and several water outlet holes are opened on the surface of the pressure plate 14, so that the hydraulic cylinder 5 can apply sufficient pressure to the pressure plate 14, and water can be effectively discharged through the several water outlet holes. A drain pipe 13 is fixedly connected to the center of the bottom surface of the water tank 2.

[0026] As an optional technical solution of this utility model, one side of the blocking gate 9 is attached to the outlet side of the filter cylinder 3. A corresponding discharge port 11 is provided at the bottom of the blocking gate 9. The diameter of the corresponding discharge port 11 and the diameter of the discharge port 10 are both adapted to the diameter of the inner wall of the filter cylinder 3. The vertical height of the blocking gate 9 is greater than twice the diameter of the filter cylinder 3, so that when the blocking gate 9 is in the rearward direction, the blocking gate 9 can press against the discharge port of the filter cylinder 3, which can effectively block the lees.

[0027] As an optional technical solution of this utility model, a support frame 7 is fixedly connected to the top of the guide frame 6, and an electric push rod 8 is fixedly connected to the center of the top surface of the support frame 7. The telescopic end of the electric push rod 8 is fixedly connected to the center of the top surface of the blocking gate 9. The height of the support frame 7 is greater than the diameter of the filter cylinder 3. After the blocking gate 9 is pulled to the top, the corresponding discharge port 11 is aligned with the inner wall of the filter cylinder 3, so that the top of the support frame 7 has sufficient space to be pulled up. After filtration, the lees can be directly pushed out by the electric push rod 8 through the alignment of the discharge port 11 with the filter cylinder 3, which facilitates discharge.

[0028] This high-efficiency filter press requires the following steps to operate:

[0029] 1) By pushing the pressure plate 14 through the hydraulic cylinder 5, the pressure plate 14 can squeeze the lees that have entered the filter cylinder 3;

[0030] 2) By applying pressure, the water is squeezed out and discharged through the filter holes on the surface of the filter cylinder 3;

[0031] 3) The filter tubes 12 located in the middle can squeeze the water inside the lees into the filter tubes 12 in the middle.

[0032] 4) After the filter press is completed, the blocking gate 9 is pulled up by the electric push rod 8, the discharge port 11 is aligned with the filter press cylinder 3, and the lees are pushed out by the electric push rod 8.

[0033] In summary, by pushing the pressure plate 14 with the hydraulic cylinder 5, the pressure plate 14 can squeeze the lees inside the filter cylinder 3. Through the squeezing force, the water is squeezed out and discharged through the filter holes on the surface of the filter cylinder 3. At the same time, the filter tubes 12 in the middle can squeeze the water inside the lees into the filter tubes 12, reducing the distance for water to be squeezed out of the lees and improving the water discharge efficiency. By pushing and pulling the electric push rod 8, the blocking gate 9 can be controlled to block the filter cylinder 3 and the corresponding discharge port 11 can be aligned with the inner wall of the filter cylinder 3, thus facilitating the switching between filtration blocking and discharge. After filtration, by aligning the discharge port 11 with the filter cylinder 3, the lees can be directly pushed out by the electric push rod 8.
