Description

Technical Field

[0001] This utility model relates to the field of filtration and separation device technology, and in particular to a filtration device for pharmaceutical equipment. Background Technology

[0002] Pharmaceuticals refer to a class of products used for prevention, treatment and diagnosis, manufactured using the principles and methods of microbiology, chemistry and other sciences. In the pharmaceutical process, it is necessary to use extrusion to separate and precipitate liquid nutrients from solid materials.

[0003] A search revealed that Chinese patent application CN221358742U discloses a filtration device for pharmaceutical equipment, which mainly uses a pressing component to squeeze impurities on the filter screen to improve resource utilization efficiency.

[0004] Compared with existing technologies in related fields, it is known that when nutrient solution is squeezed and separated from solid materials, the lower solid material is subjected to greater force and will precipitate nutrient solution first. The upper solid material will precipitate nutrient solution later as the pressure increases. During the separation process, the nutrient solution precipitated at the upper end is easily reabsorbed by the material at the lower end, resulting in incomplete precipitation of nutrient solution, which leads to waste of nutrient solution and affects the efficiency and quality of separation. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for pharmaceutical equipment in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A filtration device for pharmaceutical equipment includes a separation cylinder, an inlet pipe, an outlet pipe and a lifting unit fixedly installed on the side of the separation cylinder, a support unit fixedly installed inside the separation cylinder, a filtration unit installed on the support unit, a cylinder cover fixedly installed on the lifting unit, the cylinder cover being located directly above the separation cylinder, and a pressing unit fixedly installed on the cylinder cover.

[0008] The filtration unit includes a filter screen, a sleeve, a mounting frame, and a motor. The filter screen is mounted on a support unit, and a material support assembly is fixedly mounted on the lower surface of the filter screen. The mounting frame is arranged on the material support assembly, and elastic components are fixedly arranged on the mounting frame. The sleeve is solidly fitted onto the elastic components, and the lower end of the sleeve is open. Filter holes are arranged on the sleeve, and the sleeve slidably connects the filter screen and the material support assembly. The motor is fixedly mounted on the lower surface of the separation cylinder, and the motor's output shaft is rotatably connected to the separation cylinder. The motor's output shaft is also fixedly connected to the material support assembly.

[0009] Furthermore, the support assembly includes a mounting base and a support frame. Both the mounting base and the support frame are fixedly installed on the lower surface of the filter screen. The mounting base is located at the center of the lower surface of the filter screen. The mounting base is fixedly connected to the output shaft of the motor. The support frame is arranged on the mounting base. The support frame and the mounting base are fixedly connected to the placement frame. The support frame is slidably connected to the sleeve.

[0010] Furthermore, the elastic component includes a telescopic rod and a spring. The telescopic rod is fixedly installed on the placement frame, and the telescopic end of the telescopic rod is fixedly connected to the upper inner end of the sleeve. The spring is sleeved on the telescopic rod.

[0011] Furthermore, the support unit includes a support base and a sliding frame. The support base is fixedly installed on the inner wall of the separation cylinder, and the sliding frame is slidably installed on the support base. The sliding frame is fixedly connected to the lower surface of the filter screen and the support frame.

[0012] Furthermore, the lifting unit includes a first hydraulic telescopic mechanism, which is fixedly installed on the side of the separating cylinder. A fixing plate is fixedly installed on the telescopic end of the first hydraulic telescopic mechanism, and the fixing plate is fixedly connected to the cylinder cover.

[0013] Furthermore, the pressing unit includes a second hydraulic telescopic mechanism, which is fixedly installed on the cylinder cover. The telescopic end of the second hydraulic telescopic mechanism is slidably connected to the cylinder cover, and a pressing plate is fixedly installed on the telescopic end of the second hydraulic telescopic mechanism. The pressing plate slides in a sealed manner inside the separation cylinder.

[0014] Furthermore, the lower inner surface of the separator is an inclined plane with one end higher than the other, and the lowest end of the inclined plane is connected to the discharge pipe.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. When solid and liquid materials are extruded and separated, the sleeve is inserted into the material. The filter holes and filter screen on the sleeve work together to quickly separate and discharge the liquid material precipitated from the solid material at different positions. This reduces the contact between the precipitated liquid material and the fixed material at the bottom, reduces the reabsorption of the precipitated liquid material by the solid material, effectively improves the efficiency and quality of liquid material separation, and reduces the waste caused by reabsorption of the separated liquid material.

[0017] 2. The motor drives the filter screen and sleeve to rotate through the mounting base and support frame, so that the material is evenly placed on the filter screen, avoiding concentrated stacking which affects the filtration effect and the service life of the filter screen. In addition, it can effectively reduce the clogging of the filter screen and sleeve by solid material due to angle issues during the filtration and separation process, and ensure the speed of liquid material discharge.

[0027] like Figures 1-6As shown, a filtration device for pharmaceutical equipment includes a separation cylinder 1. A feed pipe 7, a discharge pipe 8, and a lifting unit are fixedly installed on the side of the separation cylinder 1. A support unit is fixedly installed inside the separation cylinder 1, and a filtration unit is installed on the support unit. A cylinder cover 2 is fixedly installed on the lifting unit, located directly above the separation cylinder 1. A pressing unit is fixedly installed on the cylinder cover 2. The lifting unit drives the cylinder cover 2 to close the separation cylinder 1. The material to be filtered and separated is added to the separation cylinder 1 through the feed pipe 7. The pressing unit compresses the material inside the separation cylinder 1. The filtration unit separates the solid and liquid materials. The solid material remains on the filtration unit, while the liquid material falls into the lower part of the separation cylinder 1 and is discharged through the discharge pipe 8, completing the material separation. After separation, the lifting unit drives the cylinder cover 2 and the pressing unit to rise, facilitating the processing of the solid material separated from the filtration unit.

[0028] like Figures 2-6As shown, the filtration unit includes a filter screen 303, a sleeve 307, a mounting frame 304, and a motor 309. The filter screen 303 is mounted on a support unit, and a material support assembly is fixedly mounted on the lower surface of the filter screen 303. The mounting frame 304 is arranged on the material support assembly, and elastic components are fixedly arranged on the mounting frame 304. The sleeve 307 is solidly fitted onto the elastic components, and the lower end of the sleeve 307 is open. Filter holes 308 are arranged on the sleeve 307. The sleeve 307 slidably connects the filter screen 303 and the material support assembly. The motor 309 is fixedly mounted on the lower surface of the separation cylinder 1, and the output shaft of the motor 309 is rotatably connected to the separation cylinder 1. The output shaft of the motor 309 is fixedly connected to the material support assembly. When the material to be filtered is added to the separation cylinder 1, the motor 309 drives the filter screen 303 to rotate through the material support assembly, adjusting the position of the filter screen 303 so that the material is evenly placed on the filter screen 303, avoiding the material from being concentrated in one position on the filter screen 303. Concentrated accumulation of material will affect the filtration efficiency and may cause excessive force deviation in different parts of the filter screen 303 during the filtration process, affecting the service life of the filter screen 303. The filter screen 303 is supported by the support unit and the material support assembly. The material to be filtered falls onto the filter screen 303, and the pressing unit squeezes the material on the filter screen 303, accelerating the flow rate of the liquid material, so that... Solid and liquid materials are better separated. Solid materials are screened out through filter screen 303, while liquid materials fall into separation cylinder 1 through filter screen 303 and filter holes 308 on sleeve 307. When the material is squeezed, due to the support of the elastic component, sleeve 307 can be inserted into the screened solid material, allowing liquid materials in solid materials of different heights to be directly and quickly discharged through filter holes 308 on sleeve 307. This reduces the flow path of liquid materials in solid materials and the amount of liquid material residue, reduces the re-absorption of liquid materials caused by the squeezed solid materials, reduces the waste of liquid materials caused by re-absorption, and effectively improves the efficiency and separation of liquid materials. During the separation of solid and liquid materials, the pressing unit compresses the elastic component through the sleeve 307 during the compression process of the solid material on the filter screen 303. The length of the sleeve 307 extending above the filter screen 303 is adjusted to avoid the sleeve 307 affecting the pressing unit. At the same time, during the separation of solid and liquid materials, the motor 309 drives the filter screen 303 and the sleeve 307 to rotate through the material support component, adjusting the contact position between the filter screen 303 and the sleeve 307 and the solid material. This effectively reduces the clogging of the filter holes 308 on the filter screen 303 and the sleeve 307 caused by the solid material due to the angle. The sleeve 307 then moves the material to ensure the speed of liquid material discharge.

[0029] like Figures 3-6As shown, the material support assembly includes a mounting base 301 and a support frame 302. Both the mounting base 301 and the support frame 302 are fixedly mounted on the lower surface of the filter screen 303. The mounting base 301 is located at the center of the lower surface of the filter screen 303. The mounting base 301 is fixedly connected to the output shaft of the motor 309. The support frame 302 is arranged on the mounting base 301. The support frame 302 and the mounting base 301 are fixedly connected to the placement frame 304. The support frame 302 is slidably connected to the sleeve 307. During the separation of solid and liquid materials, the motor 309 drives the filter screen 303 to rotate through the mounting base 301 and the support frame 302. At the same time, the mounting base 301 and the support frame 302 support the filter screen 303, improving the stability of the filter screen 303, reducing the deformation of the filter screen 303 during the extrusion process, and enabling the filter screen 303 to better filter and separate materials.

[0030] like Figure 4 , Figure 5 As shown, the elastic component includes a telescopic rod 305 and a spring 306. The telescopic rod 305 is fixedly installed on the placement frame 304. The telescopic end of the telescopic rod 305 is fixedly connected to the upper inner end of the sleeve 307. The spring 306 is sleeved on the telescopic rod 305. The sleeve 307 is supported by the spring 306 and the telescopic rod 305, so that the upper end of the sleeve 307 can be kept above the filter screen 303. When the force on the sleeve 307 during the filtration and separation process exceeds the limit of the spring 306, the sleeve 307 squeezes the spring 306 and the telescopic rod 305. When the force on the sleeve 307 disappears, the sleeve 307 can be reset under the elastic force of the spring 306.

[0031] like Figure 3 , Figure 4 , Figure 6 As shown, the support unit includes a support base 402 and a sliding frame 401. The support base 402 is fixedly installed on the inner wall of the separation cylinder 1, and the sliding frame 401 is slidably installed on the support base 402. The sliding frame 401 is fixedly connected to the lower surface of the filter screen 303 and the support frame 302. The support base 402 and the sliding frame 401 support and limit the filter screen 303, thereby improving the stability of the filter screen 303. When the filter screen 303 rotates, the filter screen 303 drives the sliding frame 401 to rotate along the support base 402.

[0032] like Figure 1 , Figure 2 As shown, the lifting unit includes a first hydraulic telescopic mechanism 501, which is fixedly installed on the side of the separating cylinder 1. A fixing plate 502 is fixedly installed on the telescopic end of the first hydraulic telescopic mechanism 501. The fixing plate 502 is fixedly connected to the cylinder cover 2. The cylinder cover 2 is moved by the first hydraulic telescopic mechanism 501, which facilitates the cylinder cover 2 to close or open the separating cylinder 1, effectively improving the convenience of moving the cylinder cover 2.

[0033] like Figure 1 , Figure 3 As shown, the pressing unit includes a second hydraulic telescopic mechanism 601, which is fixedly installed on the cylinder cover 2. The telescopic end of the second hydraulic telescopic mechanism 601 is slidably connected to the cylinder cover 2. A pressing plate 602 is fixedly installed on the telescopic end of the second hydraulic telescopic mechanism 601. The pressing plate 602 slides in a sealed manner inside the separation cylinder 1. After the material to be filtered and separated is placed inside the separation cylinder 1, the pressing plate 602 is moved inside the separation cylinder 1 by the second hydraulic telescopic mechanism 601. The pressing plate 602 squeezes the material inside the separation cylinder 1, so that the liquid material and the solid material are better separated, improving the separation efficiency and reducing the residue and waste of liquid material.

[0034] like Figure 3 As shown, the lower inner surface of the separator 1 is an inclined surface with one end higher than the other. The lowest end of the inclined surface is connected to the discharge pipe 8. The inclined surface design with one end higher than the other can guide the filtered and separated liquid material, allowing the liquid material to enter the discharge pipe 8 for better discharge.

[0035] Working principle: such as Figures 1-6 As shown, the cylinder cover 2 is moved by the first hydraulic telescopic mechanism 501, and the cylinder cover 2 closes the separation cylinder 1. The material to be filtered and separated is added into the separation cylinder 1 through the feed pipe 7. The motor 309 drives the filter screen 303 to rotate through the mounting base 301 and the support frame 302, and adjusts the position of the filter screen 303 so that the material is evenly placed on the filter screen 303.

[0036] like Figure 1 , Figure 3 As shown, the second hydraulic telescopic mechanism 601 drives the pressure plate 602 to move inside the separation cylinder 1. The pressure plate 602 squeezes the material inside the separation cylinder 1. Solid material is left on the filter screen 303, and liquid material falls into the separation cylinder 1 through the filter screen 303 and the filter holes 308 on the sleeve 307, and is discharged and collected through the discharge pipe 8.

[0037] like Figures 3-6 As shown, when the pressure plate 602 squeezes the material on the filter screen 303, the sleeve 307 can be inserted into the screened solid material due to the support of the spring 306 and the telescopic rod 305, so that the liquid material in the solid material at different heights can be directly and quickly discharged through the filter hole 308 on the sleeve 307, thereby improving the separation efficiency.

[0038] like Figures 3-6 As shown, when the force on the sleeve 307 exceeds the limit of the spring 306 as the pressure plate 602 descends, the sleeve 307 squeezes the spring 306 and the telescopic rod 305 to prevent the sleeve 307 from affecting the operation of the pressure plate 602.

[0039] like Figures 2-6 As shown, during the separation of solid and liquid materials, the motor 309 drives the filter screen 303 to rotate through the mounting base 301 and support frame 302, adjusting the contact position between the filter screen 303 and the sleeve 307 and the solid material, effectively reducing the blockage of the filter holes 308 on the filter screen 303 and the sleeve 307 caused by the solid material due to the angle problem. Then, the sleeve 307 moves the material to ensure the speed of liquid material discharge.

[0040] like Figures 1-3 As shown, after the material is filtered and separated, the pressure plate 602 is moved in the opposite direction by the second hydraulic telescopic mechanism 601, and the cylinder cover 2 is moved in the opposite direction by the first hydraulic telescopic mechanism 501, so that the cylinder cover 2 and the pressure plate 602 are separated from the separation cylinder 1, and the solid material in the separation cylinder 1 can be processed. After the solid material in the filter screen 303 is processed, the sleeve 307 can be reset under the elastic force of the spring 306.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
