Description

Technical Field

[0001] This utility model belongs to the technical field of impurity removal equipment, and in particular relates to an impurity removal equipment for diluent production. Background Technology

[0002] Diluents are commonly used to adjust the concentration of materials and other concentration-related properties, such as viscosity. In particular, pharmaceutical diluents can adjust drug concentration to avoid overuse and unnecessary side effects, while improving drug absorption and distribution, thereby enhancing drug bioavailability and therapeutic efficacy.

[0003] Pharmaceutical diluents require impurity removal during the production process, especially since contaminants generated during production, such as dirt from production equipment, metal ions, and dust and particulate matter from the production environment, can significantly impact the product quality and safe use in the medical field.

[0004] For example, Chinese patent application No. (2022234544704) discloses a diluent production impurity removal device. This application drives a rotating seat to rotate by a motor, thereby causing the outlet of the feed channel opened radially on the rotating seat to rotate, thus realizing the dispersed falling of the diluent. However, it requires a motor to drive it, which increases energy consumption. Moreover, although the outlet of its feed channel is rotating, there is only one outlet. Although the diluent falls in a dispersed manner relative to the filter screen, its uniformity is not good. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a purification device for diluent production that achieves the effect of uniform, dispersed feeding without the need for additional power.

[0006] In view of this, the present invention provides a purification device for diluent production, comprising:

[0007] The tank body has an inlet and an outlet, and an inlet pipe extending into the tank body is provided at the inlet;

[0008] The equalizing head is installed at one end of the feed pipe inside the tank, and has multiple feed holes along the axial direction of the tank and multiple slots along the radial circumference of the tank.

[0009] The first filter screen is installed below the distributor and is used for primary filtration of the diluent;

[0010] The second filter screen is installed below the first filter screen and is used for secondary filtration of the diluent;

[0011] The slots are arranged parallel to the axial direction of the tank body.

[0012] In the above technical solution, the evenly distributed head further includes:

[0013] A quantity adjustment component is installed inside the equalizing head and is used to automatically adjust the number of openings of multiple feed holes according to the feed rate of the diluent;

[0014] The orifice adjustment assembly is installed inside the equalizing head and is used to automatically adjust the opening size of multiple slots according to the feed rate of the diluent.

[0015] In the above technical solution, the caliber adjustment component further includes:

[0016] The partition is slidably connected inside the equalizing head and has multiple round holes;

[0017] Multiple slots are set perpendicular to the baffle, and the opening size of the multiple slots near the feed pipe is adjusted by moving the baffle.

[0018] In the above technical solution, the caliber adjustment component further includes:

[0019] A spring is installed between the axial inner wall of the equalizer and the partition plate;

[0020] When the feed rate of the feed pipe is large, the spring will be compressed and the opening size of multiple slots near the feed pipe will be increased.

[0021] In the above technical solution, the quantity adjustment component further includes:

[0022] The first guide tube has one end connected to the round hole and is flush with the upper surface of the partition plate, and the other end extends out through the feed hole to form a distribution head.

[0023] The second guide tube is connected at one end to the round hole and extends above the upper surface of the partition plate, while the other end extends out through the feed hole to form a distribution head.

[0024] The first and second guide pipes are alternately arranged.

[0025] In the above technical solution, further:

[0026] Both the first and second guide tubes form flow gaps between themselves and the inner wall of the feed hole.

[0027] Furthermore, the above technical solution also includes:

[0028] The filter cartridge is installed between the first filter screen and the second filter screen, with one end connected to the filter surface of the first filter screen and the other end having a cover.

[0029] In the above technical solution, further:

[0030] The first filter screen is arranged around the filter cylinder and is tilted to one side of the filter cylinder;

[0031] The filter cartridge has the same filtration accuracy as the first filter screen.

[0032] The beneficial effects of this utility model are as follows:

[0033] 1. By setting a dividing head at one end of the feed pipe located in the tank, and opening multiple feed holes along the axial direction and multiple slots along the radial circumference on the dividing head, the diluent entering the feed pipe can be evenly divided into multiple outlets along the axial and radial directions and fall evenly onto the first filter screen. This can effectively improve the dispersion effect of the diluent, improve the filtration efficiency, and avoid additional energy consumption.

[0034] 2. By adjusting the number of feed holes opened by the quantity adjustment component, the diluent can be evenly distributed and fed and impurities removed even when the feed amount is small, avoiding local accumulation of diluent on the first filter screen and improving the filtration effect and efficiency.

[0035] 3. By adjusting the opening size of the slot through the orifice adjustment component, the pressure of the diluent entering the tank through the slot can be guaranteed. In other words, the diluent can be sprayed at the slot, allowing it to be filtered through the first filter screen on the side away from the axis, further ensuring the uniformity of diluent dispersion and impurity removal.

[0036] 4. By setting a filter cartridge connected to the first filter screen and having the same filtration accuracy as the first filter screen in the first and second filter screens, when the feed rate is too large, that is, when there is too much diluent on the first filter screen, the diluent can be piled up in the filter cartridge. The pressure can be used to make the diluent in the filter cartridge appear as a spray, which can ensure that the diluent is uniformly filtered through the first and second filter screens, and further improve the uniformity and efficiency of removing impurities from the diluent.

[0041] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0042] Example 1:

[0043] This embodiment provides a purification device for diluent production, including:

[0044] The tank body 1 has an inlet 2 and an outlet 3, and an inlet pipe 4 extending into the tank body 1 is provided at the inlet 2.

[0045] The equalizing head 5 is installed at one end of the feed pipe 4 located inside the tank body 1, and has multiple feed holes 6 along the axial direction of the tank body 1, and multiple slots 7 along the radial circumference of the tank body 1.

[0046] The first filter screen 8 is installed below the equalizer head 5 and is used for primary filtration of the diluent;

[0047] The second filter screen 9 is installed below the first filter screen 8 and is used for secondary filtration of the diluent;

[0048] Among them, the slot 7 is set parallel to the axial direction of the tank body 1;

[0049] Meanwhile, the tank body 1 may include an upper cover and a lower cover, and the feed pipe 4 may be welded to the upper cover. Both the first filter screen 8 and the second filter screen 9 may be metal filter screens, and the filtration accuracy of the second filter screen 9 is higher than that of the first filter screen 8.

[0050] As can be seen from this embodiment, by setting a dividing head 5 at one end of the feed pipe 4 located in the tank body 1, and opening multiple feed holes 6 along the axial direction on the dividing head 5, and opening multiple slots 7 along the radial circumference, the diluent entering the feed pipe 4 can be evenly divided into multiple outlets along the axial and radial directions and fall evenly onto the first filter screen 8, which can effectively improve the dispersion effect of the diluent, improve the filtration efficiency, and avoid additional energy consumption and increase energy consumption.

[0051] Furthermore, the groove 7, which is parallel to the axis of the tube, is used as the feed hole 6. This can reduce the radial outflow of diluent when the feed amount is small, effectively ensuring the uniformity of the diluent flowing into the first filter screen 8 and ensuring the filtration effect.

[0052] Example 2:

[0053] This embodiment provides a purification device for diluent production. In addition to the technical solutions of the above embodiments, it also has the following technical features, and further includes:

[0054] A quantity adjustment component 10 is installed inside the equalizing head 5 and is used to automatically adjust the number of openings of multiple feed holes 6 according to the feed rate of the diluent.

[0055] The orifice adjustment component 11 is installed inside the equalizing head 5 and is used to automatically adjust the opening size of multiple slots 7 according to the feed rate of the diluent.

[0056] As can be seen from this embodiment, by adjusting the number of openings of the feed hole 6 by the quantity adjustment component 10, the diluent can be evenly dispersed and fed and impurities removed even when the feed amount is small, avoiding local accumulation of the diluent on the first filter screen 8, and improving the filtration effect and efficiency.

[0057] By adjusting the opening size of the slot 7 through the orifice adjustment component 11, the pressure of the diluent entering the tank 1 through the slot 7 can be guaranteed. In other words, the diluent can be sprayed at the slot 7, so that the diluent can be filtered through the side of the first filter screen 8 away from the axis, further ensuring the uniformity of diluent dispersion and impurity removal.

[0058] Example 3:

[0059] This embodiment provides a purification device for diluent production. In addition to the technical solutions of the above embodiments, it also has the following technical features: the orifice adjustment component 11 includes:

[0060] The partition 110 is slidably connected inside the equalizing head 5 and has multiple round holes 111.

[0061] The multiple slots 7 are all set perpendicularly to the partition plate 110, and the opening size of the multiple slots 7 near the feed pipe 4 is adjusted by moving the partition plate 110.

[0062] As can be seen from this embodiment, by using the partition 110, it is easy to adjust the slot 7, ensuring the pressure of the diluent entering the tank 1 through the slot 7, so that the diluent is sprayed. The opening of multiple round holes 111 makes it easy for the diluent to enter the tank 1 through the feed hole 6 after passing through the round holes 111.

[0063] Example 4:

[0064] This embodiment provides a purification device for diluent production. In addition to the technical solutions of the above embodiments, it also has the following technical features: the orifice adjustment component 11 further includes:

[0065] Spring 112 is installed between the inner wall of the equalizing head 5 and the partition plate 110 in the axial direction;

[0066] When the feed rate of the feed pipe 4 is large, the spring 112 will be compressed, and the opening size of the multiple slots 7 near the feed pipe 4 will be increased.

[0067] As can be seen from this embodiment, the spring 112 is designed so that when the amount of diluent fed is large, i.e., the amount of feed is greater than the total outflow of feed hole 6 and slot hole 7, it will accumulate on the partition plate 110, thereby pressing down the spring 112 and causing the partition plate 110 to move down, thereby increasing the opening of slot hole 7 and increasing the outflow of slot hole 7. In addition, the spring 112 will give the fluid in the equalizing head 5 a certain pressure, so that the diluent flowing out of slot hole 7 is sprayed, thereby improving the uniformity of feed and allowing the diluent to fall to the side of the first filter screen 8 away from the radial direction, improving the uniformity of the diluent on the first filter screen 8 and ensuring filtration efficiency.

[0068] Example 5:

[0069] This embodiment provides a purification device for diluent production. In addition to the technical solutions of the above embodiments, it also has the following technical features: the quantity adjustment component 10 includes:

[0070] The first guide tube 100 has one end connected to the round hole 111 and is flush with the upper end face of the partition plate 110, and the other end extends out through the feed hole 6 to form the equalizing head 5.

[0071] The second guide tube 101 is connected at one end to the round hole 111 and extends above the upper end face of the partition plate 110, while the other end extends through the feed hole 6 to form the equalizing head 5.

[0072] The first guide tube 100 and the second guide tube 101 are alternately arranged, and the first guide tube 100 and the second guide tube 101 can be interference-fitted with the circular hole 111.

[0073] As can be seen from this embodiment, by setting up the first guide pipe 100 and the second guide pipe 101, and with the inlet of the second guide pipe 101 being higher than that of the first guide pipe 100, it can be seen that when the amount of diluent fed is small, feeding is only done through the first guide pipe 100, which can ensure the uniformity of the diluent falling onto the first filter screen 8 and ensure filtration efficiency. However, when the amount of diluent fed is large, it overflows the inlet of the second guide pipe 101, and feeding can be done through both the first guide pipe 100 and the second guide pipe 101, automatically controlling the feeding speed. The structure is simple.

[0074] Example 6:

[0075] This embodiment provides a purification device for diluent production, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0076] A flow gap 12 is formed between the first guide tube 100 and the second guide tube 101 and the inner wall of the feed hole 6.

[0077] As can be seen from this embodiment, by forming a flow gap 12 between the first guide tube 100 and the second guide tube 101 and the inner wall of the feed hole 6, the diluent located in the equalizing head 5 and below the partition plate 110 can be discharged from the flow gap 12 and will not be deposited there, thus ensuring the control of the feed amount and ensuring the feed accuracy.

[0078] Furthermore, the setting of the flow gap 12 facilitates the first guide pipe 100 and the second guide pipe 101 to move up and down with the partition 110, increasing additional frictional resistance, thereby affecting the up and down movement of the partition 110 and ensuring automatic control of the opening size of the slot 7.

[0079] Example 7:

[0080] This embodiment provides a purification device for diluent production. In addition to the technical solutions of the above embodiments, it also has the following technical features, and further includes:

[0081] The filter cartridge 13 is installed between the first filter screen 8 and the second filter screen 9, with one end connected to the filter surface of the first filter screen 8 and the other end provided with a cover 14.

[0082] The filter cartridge 13 can be welded to the first filter screen 8 and the cover 14.

[0083] As can be seen from this embodiment, by setting a filter cartridge 13 on the first filter screen 8 and the second filter screen 9, when the feed amount is too large, that is, when there is too much diluent on the first filter screen 8, the diluent can be piled up in the filter cartridge 13. The pressure of the liquid level in the filter cartridge 13 makes the diluent in the filter cartridge 13 appear to be sprayed, which can ensure that the diluent is uniformly filtered through the first filter screen 8 and the second filter screen 9, and further improve the uniformity and efficiency of removing impurities from the diluent.

[0084] Furthermore, the arrangement of the filter cartridge 13 can effectively increase the effective filtration area of ​​the first filter screen 8, thereby effectively improving the filtration effect of the first filter screen 8.

[0085] Example 8:

[0086] This embodiment provides a purification device for diluent production, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0087] The first filter screen 8 is arranged around the filter cylinder 13 and is inclined to one side of the filter cylinder 13;

[0088] The filtration accuracy of the filter cartridge 13 is the same as that of the first filter screen 8.

[0089] As can be seen from this embodiment, by arranging the first filter screen 8 around the filter cylinder 13 and tilting it to one side of the filter cylinder 13, it is easier for the filtered impurities to be flushed into the filter cylinder 13, so that the filtered impurities are not easy to accumulate on the first filter screen 8, and will not have too much impact on the filtration area of ​​the first filter screen 8, thereby ensuring the filtration effect of the first filter screen 8 and extending its service life.

[0090] The filtration precision of filter cartridge 13 is the same as that of the first filter screen 8 to avoid affecting the filtration effect on the diluent due to different filtration precision.

[0091] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
