Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a purging fixture. Background Technology

[0002] In pharmaceutical processing, raw materials need to be transferred between different processing equipment. For powdered or granular drugs, during this transfer, they may adhere to the discharge valve of the discharging equipment, specifically the flange. Therefore, the discharge valve cannot completely seal when closed, leading to slight leakage when the next batch of drugs is processed. Furthermore, during the transfer of the next batch, because the previous batch's drug still adheres to the flange of the discharge valve, mixing of different batches can occur, affecting the quality of the drugs.

[0003] Therefore, there is an urgent need for a purging fixture to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a purging fixture that can purge away the material adhering to the inclined surface of the discharge valve flange, thereby preventing slight leakage of medicines during processing and avoiding mixing of different batches of medicines.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A purging fixture includes a connecting flange and a connecting pipe fitting. The connecting flange is connected to a discharge valve flange in a discharge device. The connecting flange has a channel inside, and the outlet of the channel faces the discharge valve flange.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0030] like Figures 1 to 4 As shown, this embodiment provides a purging fixture, including a connecting flange 1 and a connecting pipe 3. The connecting flange 1 is connected to the discharge valve flange 100 in the discharge equipment. The connecting flange 1 is mounted on the valve at the inlet of the processing equipment used to receive materials. A channel 11 is provided inside the connecting flange 1, with the outlet of the channel 11 facing the discharge valve flange 100. One end of the connecting pipe 3 is connected to the channel 11, and the other end is connected to the air blowing assembly. Therefore, after the discharge equipment completes the discharge of medicine, the connecting pipe 3 can be connected to the air blowing assembly. The airflow output by the air blowing assembly is delivered to the discharge valve flange 100 through the channel 11 inside the connecting flange 1. The airflow can blow off the medicine attached to the discharge valve flange 100. When the discharge valve is closed, it can completely seal, thus avoiding slight leakage of medicine when the discharge equipment processes the next batch of medicine, and also preventing the mixing of different batches of medicine.

[0031] In this embodiment, the air blowing assembly includes an air blowing body and a delivery pipe. The air blowing body includes a housing and a rotating component disposed inside the housing. The housing has several vent holes and a delivery hole. One end of the delivery pipe is connected to a connecting pipe, and the other end is connected to the delivery hole. When the rotating component rotates, it generates centrifugal airflow, allowing air to enter the housing through the vent holes and be delivered to the connecting pipe along the delivery pipe. Specifically, the rotating component includes a motor and fan blades. When the motor rotates, it drives the fan blades to rotate, thereby generating centrifugal airflow. Specifically, a centrifugal fan can be used for the air blowing assembly. The working principle and specific structure of the air blowing assembly can be referred to in the prior art, and will not be elaborated further here.

[0032] The purging fixture provided in this embodiment has a channel 11 on the connecting flange 1, with the outlet of the channel 11 facing the discharge valve flange 100 of the discharge equipment. The channel 11 is connected to the air blowing assembly through the connecting pipe 3, so that the airflow output by the air blowing assembly can be delivered to the discharge valve flange 100 through the channel 11, blowing off the medicine attached to the discharge valve flange 100. This ensures that the discharge valve can be completely sealed when closed, avoiding slight leakage during the processing of the next batch of medicine, and also preventing the mixing of different batches of medicine.

[0033] In this embodiment, the air blowing assembly can also be replaced with a cleaning assembly, and the cleaning water output by the cleaning assembly can be used to wash away the medicine adhering to the discharge valve flange 100.

[0034] In this embodiment, channel 11 includes a first channel 111 and a second channel 112 that are connected to each other. The first channel 111 is connected to the connecting pipe 3. The second channel 112 includes a storage section 1121 and a flow section 1122 that are connected to each other. The volume of the flow section 1122 is smaller than the volume of the storage section 1121. The storage section 1121 is connected to the first pipe, and the outlet of the flow section 1122 faces the discharge valve flange 100. By setting the storage section 1121 in the second channel 112, the airflow output by the purging assembly is transported to the discharge valve flange 100 position through the flow section 1122 after filling the storage section 1121. The storage section 1121 can buffer the airflow output by the purging assembly, so that the airflow can be evenly delivered to the discharge valve flange 100 position, further improving the smoothness of airflow.

[0035] For example, the longitudinal cross-sectional shape of the storage section 1121 is triangular. Of course, the longitudinal cross-sectional shape of the storage section 1121 can also be rectangular, pentagonal or irregular, as long as the volume of the storage section 1121 is greater than the volume of the flow section 1122, so that the airflow output by the purging assembly can be buffered. There are no specific restrictions on the longitudinal cross-sectional shape of the storage section 1121 here.

[0036] As a preferred option, such as Figure 5 As shown, a protrusion 10 is provided on the side of the connecting flange 1 opposite to the discharge valve flange 100. When the discharge valve flange 100 and the connecting flange 1 are connected, the protrusion 10 fits snugly against the discharge valve flange 100. The protrusion 10 ensures that the airflow output from the purging assembly can flow smoothly out of the channel 11, quickly blowing off the medicine adhering to the discharge valve flange 100. Specifically, the thickness of the protrusion 10 is 0.2mm-0.4mm to avoid the problem of medicine leakage during medicine conveying due to excessive gap between the two. Of course, a small gasket can also be set between the discharge valve flange 100 and the connecting flange 1 at the fitting point. The gasket will not block the outlet of the channel 11, and can also achieve a stable connection between the discharge valve flange 100 and the connecting flange 1 while the airflow output from the purging assembly can flow smoothly out of the channel 11.

[0037] In this embodiment, the connecting fitting 3 includes a guide pipe 31 and a connector 32. One end of the guide pipe 31 is connected to the channel 11, and the other end is connected to the connector 32. Depending on the specifications of the purging assembly, the specifications of the connector 32 can be changed to improve the ease of use of the purging fixture. Specifically, the guide pipe 31 is welded to the connecting flange 1 at the location where the channel 11 is set, making the connection between the guide pipe 31 and the connecting flange 1 more secure. Alternatively, an internal thread can be provided on the inner wall of the first channel 111, and an external thread can be provided on the outer wall of the guide pipe 31, allowing the guide pipe 31 to connect to the first channel 111 via a threaded connection, thereby enabling the guide pipe 31 to communicate with the channel 11.

[0038] In this embodiment, the connecting flange 1 and the discharge valve flange 100 are connected by fasteners 2. This allows the fit between the discharge valve flange 100 and the connecting flange 1 to be adjusted by adjusting the fasteners 2, so that the discharge valve flange 100 and the connecting flange 1 are in a suitable fit. This ensures that the connection between the two is stable and that the airflow output by the purging assembly can be smoothly delivered to the position of the discharge valve flange 100.

[0039] For example, a first positioning hole 101 is provided on the discharge valve flange 100, and a second positioning hole 12 is provided on the connecting flange 1. The fastener 2 passes through the second positioning hole 12 and locks itself in the first positioning hole 101, thereby connecting the discharge valve flange 100 and the connecting flange 1 via the fastener 2. Specifically, the first positioning hole 101 has an internal thread, and the fastener 2 has an external thread. During assembly, after the fastener 2 passes through the second positioning hole 12, the external thread on the fastener 2 engages with the internal thread of the first positioning hole 101, thereby locking the fastener 2 in the first positioning hole 101. In this embodiment, the fastener 2 can be a bolt or a stud.

[0040] Preferably, the purging fixture also includes a washer 4, which fits against the outer periphery of the second positioning hole 12. When the bolts are tightened to lock the discharge valve flange 100 and the connecting flange 1, the head of the bolts fits against the washer 4, which prevents the bolts from causing wear on the surface of the connecting flange 1 after tightening the discharge valve flange 100 and the connecting flange 1, thus ensuring the smoothness of the surface of the connecting flange 1.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
