Description

Technical Field

[0001] The utility model relates to the technical field of dust removal of tablet presses, in particular to a dust removal device for a tablet press. Background Art

[0002] A tablet press is a device that compresses powdered or granular materials through a specific processing process. Its primary function is to compress, consolidate, and shape the material to suit specific processing and usage requirements. During the tableting process, the vibration and conveying of pharmaceutical powders in the tablet press inevitably generate a lot of dust. The surface of the tablets often becomes dusty after compression. This dust can spread into the air, causing pollution and material loss, making it difficult to meet the requirements of existing technologies.

[0003] Dust removal devices for tablet presses have also appeared in the prior art. Most of the dust removal devices for tablet presses in the prior art are connected to the dust removal device at the air outlet of the tablet press, and the dust from the tablet press is separated and removed through the filter in the dust removal device. However, dust removal through only a single filter has a poor dust filtering effect, and dust removal through the filter is likely to cause the filter to be blocked once too much dust accumulates, thereby affecting the normal dust removal of the dust removal device. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides a tablet press dust removal device, which can effectively remove dust from the tablet press and prevent dust accumulation, thereby achieving better dust removal effect.

[0007] Furthermore, the adsorption mechanism includes a suction pipe, an induced draft fan and an exhaust pipe. The induced draft fan is installed at the bottom of the adsorption barrel. The induced draft end of the induced draft fan is connected to the suction pipe, and the discharge end of the induced draft fan is connected to the exhaust pipe.

[0008] Furthermore, a bellows is provided in the middle of the suction pipe, and one end of the suction pipe away from the induced draft fan passes through the sealing cover plate to the dust collecting barrel.

[0009] Furthermore, a connecting plate is installed on the top of the dust filter cloth, and the connecting plate is a mesh plate. The connecting plate is in active contact with the vibrating end of the vibration motor.

[0010] Furthermore, a connecting pipe is provided through the top of the dust separation barrel, and the connecting pipe is connected to the dust exhaust end of the tablet press.

[0011] From the above technical solution, it can be seen that the beneficial effects of the utility model are:

[0012] The utility model provides an adsorption barrel and a dust separation barrel, and an air guide pipe is provided between the adsorption barrel and the dust separation barrel, so as to facilitate multi-stage processing of the tablet press, improve the dust removal effect, and prevent the discharged gas from polluting the environment; by installing a vibration motor at the bottom of the sealing cover plate, the vibration end of the vibration motor is in active contact with the dust filter cloth, and the dust filter cloth can be vibrated by the vibration motor, so as to effectively knock down the dust filtered on the dust filter cloth, thereby preventing the accumulation of dust and causing poor filtering effect.

[0017] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0018] See Figure 1: A dust removal device for a tablet press comprises an adsorption barrel 1 and a dust separation barrel 10, an air duct 9 being connected between the adsorption barrel 1 and the dust separation barrel 10, the adsorption barrel 1 is provided with a dust collecting barrel 8, the air duct 9 passes through the dust collecting barrel 8, a dust filter cloth 7 is movably installed in the dust collecting barrel 8, a sealing cover plate 2 is movably installed on the top of the dust collecting barrel 8, a vibration motor 3 is installed at the bottom of the sealing cover plate 2, the vibrating end of the vibration motor 3 is in movably contact with the dust filter cloth 7, an adsorption mechanism is provided at the bottom of the adsorption barrel 1, the adsorption mechanism passes through the sealing cover plate 2 to the adsorption barrel 1; the bottom of the dust separation barrel 10 is hollow, and a powder loading barrel 11 is movably installed at the bottom of the dust separation barrel 10.

[0019] By setting up an adsorption barrel 1 and a dust separation barrel 10, and setting an air guide pipe 9 between the adsorption barrel 1 and the dust separation barrel 10, it is convenient to perform multi-stage processing on the tablet press, the dust removal effect is better, and the discharged gas is prevented from polluting the environment; by installing a vibration motor 3 at the bottom of the sealing cover plate 2, the vibrating end of the vibration motor 3 is in active contact with the dust filter cloth 7, and the dust filter cloth 7 can be vibrated by the vibration motor 3, so that the dust filtered on the dust filter cloth 7 is effectively knocked off, thereby preventing the accumulation of dust and causing poor filtering effect.

[0020] In this embodiment, the adsorption mechanism includes a suction pipe 4, an induced draft fan 5 and an exhaust pipe 6. The induced draft fan 5 is installed at the bottom of the adsorption barrel 1. The induced draft end of the induced draft fan 5 is connected to the suction pipe 4, and the discharge end of the induced draft fan 5 is connected to the exhaust pipe 6. Specifically, by starting the induced draft fan 5, the suction pipe 4 generates suction, so that the adsorption barrel 1 has suction. Through the setting of the air guide pipe 9, suction is simultaneously generated in the dust separation barrel 10, thereby adsorbing the dust in the tablet press through the connecting pipe 12 to treat it.

[0021] In this embodiment, a bellows 401 is provided in the middle of the suction pipe 4, and the end of the suction pipe 4 away from the induced draft fan 5 passes through the sealing cover plate 2 to the dust collecting cylinder 8; specifically, the bellows 401 is provided in the middle of the suction pipe 4 to facilitate the movement of the suction pipe 4, so that it can adapt to the disassembly and assembly of the sealing cover plate 2 when replacing the dust filter cloth 7.

[0022] Among them, sealing gaskets are provided around the sealing cover plate 2 to ensure the airtightness after the sealing cover plate 2 and the adsorption barrel 1 are connected.

[0023] In this embodiment, a connecting plate 13 is installed on the top of the dust filter cloth 7. The connecting plate 13 is a mesh plate. The connecting plate 13 is in active contact with the vibrating end of the vibration motor 3. Specifically, the connecting plate 13 can be provided to facilitate the installation of the dust filter cloth 7, thereby facilitating the processing of the adsorbed dust.

[0024] Among them, the working principle of the dust separation barrel 10 is: the dust from the tablet press enters the dust separation barrel 10 through the connecting pipe 12, and through the joint action of the outer vortex A and the inner vortex B, the low-density gas can rise and the high-density dust can fall, thereby achieving the effect of separating the dust from the air. This separation method belongs to the existing technology, so it is not described in detail in the specification and the drawings of the specification. The separated dust falls into the detachable powder loading barrel 11 for collection, and the air enters the adsorption barrel 1 through the air duct 9 for further processing.

[0025] In this embodiment, a connecting pipe 12 is provided through the top of the dust separation barrel 10, and the connecting pipe 12 is connected to the dust exhaust end of the tablet press. Specifically, by providing the connecting pipe 12, it is convenient to adsorb the dust in the tablet press, thereby facilitating its treatment.

[0026] Working principle: The staff connects the connecting pipe 12 with the dust exhaust end of the tablet press. After connection, the induced draft fan 5 is controlled to start, so that the suction pipe 4 generates suction and transmits it to the adsorption barrel 1. Through the air duct 9 arranged between the adsorption barrel 1 and the dust separation barrel 10, the dust separation barrel 10 also has suction, so that the dust in the tablet press can be adsorbed through the connecting pipe 12. After the dust is adsorbed into the dust separation barrel 10, the dust is initially filtered through the dust separation barrel 10. The filtered air enters the dust collecting barrel 8 through the air duct 9. Under the action of suction, the remaining dust in the air enters the dust filter cloth 7, and the dust filter cloth 7 adsorbs the remaining dust in the air, which can effectively adsorb the dust in the tablet press. The vibration motor 3 is started at a regular time to drive the dust filter cloth 7 to vibrate, effectively shaking off the dust into the dust collecting barrel 8, preventing excessive dust from clogging the dust filter cloth 7 and causing poor filtering effect, thereby preventing environmental pollution while also collecting dust.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
