Description

Technical Field

[0001] The utility model relates to the technical field of homogenizers, and particularly relates to a feeding device for suspending liquid homogenization. Background Art

[0002] Since the particles in the suspension have a large dispersion degree, some suspensions in the field of pharmaceutical preparation or cosmetic preparation usually need to be homogenized and mixed by using a homogenization device. The principle is that a high-pressure piston pump is used to make the suspension pass through the homogenization valve at a high speed, and the suspension realizes homogenization under the combined effects of high-speed impact, shearing and pressure-loss explosion in the homogenization valve.

[0003] In this process, first, a feeding device is needed to introduce the suspension to be homogenized into the piston pump. In some scenarios, quantitative feeding needs to be realized. Therefore, a graduated measuring cup is generally used as the feeding device, and the amount of the suspension loaded is measured by the scale.

[0004] Although this kind of graduated measuring cup can realize quantitative feeding, there are still disadvantages in actual use. For example, every time the suspension is poured into the measuring cup, it is necessary to closely monitor the scale line and stop when the liquid level in the measuring cup reaches the required scale. If an operation error occurs and the liquid level is too high, the suspension in the measuring cup needs to be pumped out. If it is too low, more needs to be added. The repeated operation is rather troublesome; moreover, during the measuring process, the suspension is likely to splash out, so it still needs to be improved. Content of the Utility Model

[0005] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a feeding device for suspending liquid homogenization.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A feeding device for suspending liquid homogenization, which is used to supply the suspension to a piston pump, includes:

[0008] A liquid storage container, which is used to store the suspension to be homogenized;

[0009] A buffer container, which has an accommodation cavity inside for receiving the suspension;

[0010] A feeding pipe, which is fixedly arranged in the accommodation cavity. An overflow hole communicating the accommodation cavity and the inside of the feeding pipe is arranged on the side wall of the feeding pipe, and a blanking port is arranged on the bottom wall of the feeding pipe; the blanking port is communicated with the feeding port of the piston pump;

[0011] A pump component, which is used to pump the suspension in the liquid storage container into the feeding pipe.

[0012] As an alternative embodiment of the present utility model, the bottom of the buffer container is provided with a liquid return port, and the liquid return port is communicated with the liquid storage container, and the liquid return port is higher than the liquid storage container.

[0013] As an alternative embodiment of the present utility model, a three-way valve is further included. The three-way valve includes three valve ports that communicate with each other, and the three valve ports are respectively communicated with the liquid outlet end of the pump member, the feed port and the discharge port of the plunger pump.

[0014] As an alternative embodiment of the present utility model, a plurality of overflow holes are sequentially formed in the side wall of the feed pipe in the vertical direction, and each overflow hole is equipped with a plug for blocking the overflow hole.

[0015] As an alternative embodiment of the present utility model, the feed pipe is detachably installed in the buffer container.

[0016] As an alternative embodiment of the present utility model, a discharge pipe is provided at the bottom of the feed pipe, and the discharge port is formed by the discharge pipe; a through hole penetrating the bottom wall of the buffer container is formed in the bottom wall of the buffer container, and the lower end of the through hole is communicated with the feed port of the plunger pump, and a step is formed on the peripheral wall of the through hole; the discharge pipe is inserted into the through hole and its lower end abuts against the step; the buffer container and the feed pipe are connected by a connecting component.

[0021] Compared with the prior art, the advantages of adopting this solution are:

[0022] In this solution, during use, the suspension in the liquid storage container can be introduced into the feed pipe through the discharge port by a pump component. As the suspension is introduced, the liquid level in the feed pipe continuously rises. When the liquid level reaches the position of the overflow hole, the suspension in the feed pipe can flow into the accommodation cavity through the overflow hole.

[0029] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0030] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating directions or positional relationships are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model.

[0031] Please refer to Figures 1-5 as shown, this embodiment provides a feeding device for homogenizing a suspension, which is used to supply the suspension to the plunger pump 2. After the plunger pump 2 extracts the suspension, it enters the homogenizing valve to achieve subsequent homogenizing work.

[0032] As Figure 1As shown, the present device includes a liquid storage container 1, a buffer container 3, a feed pipe 4, a pump member 5, etc., and the following is a specific description:

[0033] The liquid storage container 1 is used to store the suspension to be homogenized.

[0034] The buffer container 3 has an accommodation cavity 31 inside for receiving the suspension, and its shape can be selected according to actual needs. For example, in this embodiment, the buffer container 3 is in a cylindrical structure with an open top.

[0035] The feed pipe 4 is vertically fixed in the accommodation cavity 31. An overflow hole 40 communicating the accommodation cavity 31 and the inside of the feed pipe 4 is provided on the side wall of the feed pipe 4, and a discharge port 411 is provided on the bottom wall of the feed pipe 4; the discharge port 411 is communicated with the feed port of the plunger pump 2.

[0036] The pump member 5 is used to pump the suspension in the liquid storage container 1 into the feed pipe 4. Specifically, the liquid inlet end of the pump member 5 is communicated with the liquid storage container 1, and the liquid outlet end is communicated with the discharge port 411. The pump member 5 can be an electronic pump, a peristaltic pump, etc., and is not specifically limited herein;

[0037] The specific connection structure among the pump member 5, the discharge port 411, and the plunger pump 2 is as follows:

[0038] As Figure 1 shown, the present device further includes a three-way valve 6. The three-way valve 6 refers to a valve with three valve ports, and each valve port can be opened and closed independently to realize the on-off of the corresponding valve port; there are many descriptions of such a three-way valve 6 in the prior art, and no more details will be given here.

[0039] The three valve ports of the three-way valve 6 are respectively communicated with the liquid outlet end of the pump member 5, the feed port of the plunger pump 2, and the discharge port 411. For the convenience of description, the three valve ports of the three-way valve 6 in this embodiment are respectively denoted as the first valve port 61, the second valve port 62, and the third valve port 63; the first valve port 61 is connected to the feed port of the plunger pump 2 through a pipeline; the second valve port 62 is connected to the liquid discharge end of the pump member 5 through a pipeline; and the third valve port 63 is communicated with the discharge port 411; the third valve port 63 can be set to an always-open state.

[0040] During feeding, operate the three-way valve 6 to close the first valve port 61 and open the second valve port 62. Then, turn on the pump member 5. The suspension in the liquid storage container 1 is drawn by the pump member 5 and flows through the pump member 5 - the second valve port 62 - the third valve port 63 - the feeding port 411 in sequence and enters the feeding pipe 4. As the drawing operation progresses, the liquid level of the suspension in the feeding pipe 4 continuously rises. When the liquid level of the suspension rises to the position of the overflow hole 40, the suspension in the feeding pipe 4 will flow out from the overflow hole 40 and then flow into the buffer container 3. After the overflow occurs, the pump member 5 can be turned off to stop the drawing. Of course, the working time of the pump member 5 can also be set. For example, when the pump member 5 has worked for the set time, the pump member 5 will automatically stop. It should be noted that the set working time should at least meet the requirement that the amount of suspension drawn by the pump member 5 within the set time can at least reach the position of the overflow hole 40.

[0041] Under the action of the overflow hole 40, the liquid level in the feeding pipe 4 can be kept at the position of the overflow hole 40. In this way, the position of the overflow hole 40 is equivalent to the quantitative position, thus achieving the purpose of quantitative feeding.

[0042] Next, when the feeding in the feeding pipe 4 is completed, the homogenization process can be started: open the first valve port 61, close the second valve port 62, and then turn on the plunger pump 2. Under the drawing of the plunger pump 2, the suspension in the feeding pipe 4 can flow through the feeding port 411 - the third valve port 63 - the first valve port 61 - the feeding port of the plunger pump 2 in sequence and enter the plunger pump 2, and then be injected into the homogenization valve by the high pressure of the plunger pump 2 for subsequent homogenization work.

[0043] In addition, in order to be able to adjust the feeding amount of the feeding pipe 4, in this embodiment, as Figure 2 shown, a plurality of overflow holes 40 are sequentially formed in the side wall of the feeding pipe 4 in the vertical direction, and each overflow hole 40 is equipped with a plug 43 for blocking the overflow hole 40. In this way, one overflow hole 40 corresponds to one liquid level. In actual use, when a certain overflow hole 40 is selected as the quantitative point, only need to use the plug 43 to block all the overflow holes 40 below this overflow hole 40. The plug 43 can be a rubber plug.

[0044] As Figure 1 shown, in addition, in order to enable the suspension that overflows into the buffer container 3 to flow back into the liquid storage container 1, in this embodiment, the bottom of the buffer container 3 has a liquid return port 32, the liquid return port 32 is communicated with the liquid storage container 1 through a pipeline, and the liquid return port 32 is higher than the liquid storage container 1.

[0045] In order to be able to disassemble and replace the feeding pipe 4, in this embodiment, the feeding pipe 4 is detachably installed in the buffer container 3. Specifically:

[0046] A feed pipe 4 is provided with a blanking pipe 41 at its bottom, and the blanking port 411 is formed by the blanking pipe 41. A through hole 33 penetrating the bottom wall of the buffer container 3 is formed in the bottom wall of the buffer container 3, and the lower end of the through hole 33 is communicated with the feed port of the plunger pump 2. Specifically, a three-way valve 6 is fixed at the bottom of the buffer container 3, and the first valve port 61 is communicated with the lower end of the through hole 33.

[0047] As Figure 5 shown, a step 331 is formed on the peripheral wall of the through hole 33. The step 331 is annular and is arranged around the peripheral wall of the through hole 33. At this time, the entire through hole 33 is equivalent to a countersunk hole structure.

[0048] The blanking pipe 41 is inserted into the through hole 33 and its lower end abuts against the step 331. The buffer container 3 and the feed pipe 4 are connected by a connecting component.

[0049] The connecting component includes a first connecting portion 71 fixed to the buffer container 3, a second connecting portion 72 fixed to the feed pipe 4, and a screw 73 vertically fixed to the first connecting portion 71. A through hole for the screw 73 to vertically pass through is formed in the second connecting portion 72. A nut 74 is threadedly connected to the screw 73, and the second connecting portion 72 is pressed against the first connecting portion 71 by the nut 74.

[0050] During assembly, align the blanking pipe 41 with the through hole 33 and the screw 73 with the through hole. Insert the blanking pipe 41 downward so that the blanking pipe 41 is inserted into the through hole 33. At the same time, the second connecting portion 72 passes through the through hole and into the screw 73. Then screw on the nut 74 to move the nut 74 downward. Finally, the nut 74 presses the second connecting portion 72 against the first connecting portion 71, so that the lower end of the blanking pipe 41 is tightly abutted against the step 331 in the through hole 33.

[0051] In order to improve the sealing performance between the lower end of the blanking pipe 41 and the step, in this embodiment, a sealing ring 42 is embedded between the step 331 and the lower end of the blanking pipe 41.

[0052] In order to prevent the suspension from directly flushing out from the top of the feed pipe 4 when the pump part 5 pumps liquid into the feed pipe 4, in this embodiment, the top of the feed pipe 4 is closed.

[0053] Optionally, the top of the feed pipe 4 is provided with an open end, and a cover plate 44 is provided at the top of the feed pipe 4. The cover plate 44 seals the open end at the top of the feed pipe 4 to achieve the closure of the top of the feed pipe 4.

[0054] Among them, the cover plate 44 is preferably detachably installed at the top of the feed pipe 4, so as to facilitate the later removal of the cover plate 44 to clean the inside of the feed pipe 4.

[0055] For example, the cover plate 44 is covered on the top of the feed pipe 4 by means of screw connection or direct threaded connection (similar to the threaded connection mode of a beverage bottle and its cap).

[0056] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
