Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a material spill prevention device for the conveyor belt of a drum filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device, and the drum filter press is one type of it. The drum filter press uses drums to squeeze the material to achieve solid-liquid separation.

[0003] For example, Chinese patent document CN215462492U discloses a drum filter press, which describes "a support frame, on which extrusion rollers, pulleys, and driven wheels are supported; a hollow conveyor belt is sleeved on the outside of the pulleys and driven wheels; a receiving hopper is also fixedly installed on the support frame; the extrusion rollers include an upper roller and a lower roller; the upper roller is mounted on the support frame via a mounting frame and adjusting bolts." This device, by having a mounting frame that is movably mounted on the support frame, can adjust the height of the mounting frame as needed, thereby changing the height of the upper roller, and ultimately adjusting the gap between the extrusion rollers according to the actual material being processed.

[0004] However, the existing technology still has the following defects or problems: When the filter press is working, the material is spread on the conveyor belt, and the water in the material is extracted by the rollers and separated by the permeable belt. In practice, due to the uneven distribution of the material on the belt, the material will deviate to both sides of the belt (in the width direction) under the squeezing force of the rollers, causing the material to accumulate on both sides or even fall directly off the conveyor belt without being dewatered, thus affecting the overall dewatering efficiency of the material.

[0005] To address the aforementioned shortcomings, a material spill prevention device for the conveyor belt of a drum filter press is proposed, which can solve the problem of material spillage. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a material spill prevention device for the conveyor belt of a drum filter press.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A material spill prevention device for a rotary drum filter press conveyor belt includes a support frame, a conveyor belt, and a driven wheel. An upper extrusion roller and a lower extrusion roller are supported on the support frame. The conveyor belt has a hollow structure and is fitted over the driven wheel and the lower extrusion roller. A receiving hopper is also fixedly mounted on the support frame. The upper extrusion roller includes an upper shaft and an upper roller, which are rotatably connected to the support frame via a bearing sleeve. The upper roller is fixedly fitted onto the outer wall of the upper shaft. The lower extrusion roller includes a lower shaft and a lower roller, which are rotatably connected to the support frame via a bearing sleeve. The lower roller is fixedly fitted onto the outer wall of the lower shaft. The upper roller is located above the lower roller. The conveyor belt is fitted over the lower roller and positioned between the upper and lower rollers. Retaining rings are fitted onto the outer walls of both ends of the upper roller.

[0009] Preferably, the upper rotating shaft and upper roller are arranged in pairs with the lower rotating shaft and lower roller, and there are at least two pairs. The distance between the pair of upper rollers and lower rollers farther away from the receiving hopper is smaller than the distance between the pair of upper rollers and lower rollers closer to the receiving hopper.

[0010] Preferably, a mounting base is slidably mounted on one side of the support frame, a tensioning wheel is rotatably mounted on the outside of the mounting base, and the conveyor belt is sleeved on the outside of the tensioning wheel.

[0011] Preferably, a motor is provided at one end of the lower rotating shaft, the output end of the motor is fixedly connected to the lower rotating shaft, and pulleys are fixedly sleeved at the other end of the lower rotating shaft, and the pulleys are connected to each other by belt drive.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, materials are conveyed on a conveyor belt, and the materials on the conveyor belt are squeezed by the upper and lower rollers. By installing retaining rings on both sides of the upper roller, when the materials deviate to the sides of the lower roller, the retaining rings can block the materials and prevent them from falling to the sides without being dehydrated, thereby improving the overall dehydration efficiency of the materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] As attached Figure 1 As shown:

[0023] A material spill prevention device for conveyor belt of a drum filter press includes a support frame 1, a conveyor belt 7, and a driven wheel 8. An upper extrusion roller and a lower extrusion roller are supported on the support frame 1. The conveyor belt 7 has a hollow structure and is sleeved on the driven wheel 8 and the lower extrusion roller. A receiving hopper 10 is also fixedly installed on the support frame 1.

[0024] In the above technical solution, when in use, the material falls from the receiving hopper 10 onto the conveyor belt 7 and moves together with the conveyor belt 7. During this process, the material is squeezed by a pair of upper and lower extrusion rollers to separate the solid and liquid components. The solid part continues to move forward with the conveyor belt 7, while the liquid part flows down through the conveyor belt 7 to be collected.

[0025] As attached Figure 2 To be continued Figure 4 As shown, the upper extrusion roller includes an upper rotating shaft 2 and an upper roller 3. The upper rotating shaft 2 and the support frame 1 are rotatably connected through a bearing sleeve. The upper roller 3 is fixedly sleeved on the outer wall of the upper rotating shaft 2. The lower extrusion roller includes a lower rotating shaft 5 and a lower roller 6. The lower rotating shaft 5 and the support frame 1 are rotatably connected through a bearing sleeve. The lower roller 6 is fixedly sleeved on the outer wall of the lower rotating shaft 5. The upper roller 3 is located above the lower roller 6. The conveyor belt 7 is sleeved on the outside of the lower roller 6 and is located between the upper roller 3 and the lower roller 6. The outer walls of both ends of the upper roller 3 are sleeved with retaining rings 4.

[0026] In the above technical solution, the material is conveyed on the conveyor belt 7, and the material on the conveyor belt 7 is squeezed by the upper roller 3 and the lower roller 6. The upper roller 3 is equipped with baffle rings 4 on both sides. When the material deviates to the sides of the lower roller 6, the baffle rings 4 can block the material and prevent the material from falling to the sides without being dehydrated, thereby improving the overall dehydration efficiency of the material.

[0027] As attached Figure 2 To be continued Figure 4 As shown, the upper roller 3 and the lower roller 6 are arranged in pairs, and there are at least two pairs. The distance between the pair of upper roller 3 and lower roller 6 that is farther away from the receiving hopper 10 is smaller than the distance between the pair of upper roller 3 and lower roller 6 that is closer to the receiving hopper 10.

[0028] In the above technical solution, the gap between the upper roller 3 and the lower roller 6 gradually decreases as the material travels, enabling step-by-step compression and solid-liquid separation. In this embodiment, as an example, there are three sets of upper roller 3 and four sets of lower roller 6. The first three sets of upper roller 3 and lower roller 6 are three pairs, and the other set of lower roller 6 is located outside the upper roller 3. The distances between each pair of upper roller 3 and lower roller 6 starting from the feed end are 160mm, 75mm, and 30mm, respectively. This allows the material to be finally compressed to a thickness of 30mm, with a moisture content of about 65% after compression.

[0029] A mounting base 11 is slidably installed on one side of the support frame 1, and a tensioning wheel 12 is rotatably installed on the outside of the mounting base 11. The conveyor belt 7 is sleeved on the outside of the tensioning wheel 12.

[0030] In the above technical solution, the mounting base 11 is slidably disposed on one side of the support frame 1 and then fixed by bolts. Since the conveyor belt 7 will gradually become loose during continuous use, the position of the mounting base 11 can be adjusted when needed, thereby adjusting the position of the tensioning wheel 12 so that the tension of the conveyor belt 7 is kept at an appropriate level.

[0031] A motor 13 is provided at one end of the lower rotating shaft 5. The output end of the motor 13 is fixedly connected to the lower rotating shaft 5. A pulley 9 is fixedly sleeved at the other end of the lower rotating shaft 5. The pulleys 9 are connected to each other by belt drive.

[0032] In the above technical solution, the motor 13 drives the lower rotating shaft 5 to rotate, and the lower rotating shaft 5 drives the lower roller 6 to rotate through the pulley 9 and the belt. Since the conveyor belt 7 is sleeved on the outside of the lower roller 6, the lower roller 6 drives the conveyor belt 7 to move.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In use, the material falls from the receiving hopper 10 onto the conveyor belt 7 and moves along with it. The material is conveyed on the conveyor belt 7, and the material on the conveyor belt 7 is squeezed by the upper roller 3 and the lower roller 6. The upper roller 3 is equipped with baffle rings 4 on both sides. When the material deviates to the sides of the lower roller 6, the baffle rings 4 can block the material and prevent it from falling from both sides to both sides, thus improving the overall dewatering efficiency of the material. In this process, the material is squeezed by the paired upper roller 3 and lower roller 6 to separate the solid and liquid. The solid part continues to move forward with the conveyor belt 7, and since the conveyor belt 7 has a hollow structure, the liquid part flows through the conveyor belt 7 to the bottom for collection.

[0035] Please refer to the above structure and process. Figure 1-5 .

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
