Description

Technical Field

[0001] The utility model belongs to the technical field of reciprocating vacuum pumps, in particular to a reciprocating vacuum pump used in pharmaceutical production. Background Art

[0002] A reciprocating vacuum pump (also known as a piston vacuum pump) is a dry vacuum pump; it relies on the reciprocating motion of the piston in the cylinder to inhale and exhaust gas. Reciprocating vacuum pumps are widely used in pharmaceutical processing.

[0003] According to the published patent with announcement number CN218093375U, a reciprocating vacuum pump for pharmaceutical production is provided. The utility model, through the setting of the limiting device, pushes the compound vacuum pump body to make the roller roll in the slide groove. After the damping compound vacuum pump body is connected to the equipment, the bottom end of the connecting strip is flipped into the limiting groove by the rotating shaft, and then the electric telescopic rod is used to push the limiting block to move to the upper and lower sides of the limiting groove, so that the limiting block and the limiting groove are engaged and limited by gears, which is conducive to conveniently adjusting the distance between the compound vacuum pump body and the equipment and facilitating the limiting of the adjusted device body. However, there are still the following shortcomings, such as:

[0004] When adjusting the position of the reciprocating vacuum pump, the device can only fine-tune the distance of the reciprocating vacuum pump. When the position needs to be moved to a farther position, the reciprocating vacuum pump is heavy overall and the device is not equipped with moving wheels, making it difficult to move. The staff needs to spend a lot of labor to adjust it, which is inefficient. Therefore, we propose a reciprocating vacuum pump for pharmaceutical production. Utility Model Content

[0005] The purpose of the utility model is to provide a reciprocating vacuum pump for pharmaceutical production, which is provided with a lifting seat, specifically, starting motor 2 to drive gear 1 to rotate slowly clockwise, then gear 2 rotates counterclockwise and drives the elliptical block to rotate counterclockwise through the rotating rod, so as to move the entire device to the required position, making the equipment transfer more convenient and quick, reducing the labor of the staff, and solving the problem that when the reciprocating vacuum pump needs to be moved to a farther position, the reciprocating vacuum pump is heavy as a whole and the equipment is not provided with moving wheels, so it is difficult to move, and the staff needs to spend a lot of labor to adjust it, which is inefficient.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a reciprocating vacuum pump for pharmaceutical production, comprising a fixed seat, a reciprocating vacuum pump body is arranged above the fixed seat, an adjustment component is arranged inside the fixed seat, a placement base is fixedly connected to the bottom of the fixed seat, the interior of the fixed seat is hollowed out, and the front and back sides of the inner wall of the fixed seat are fixedly connected to slide rails;

By setting the lifting seat, specifically starting motor 2 to drive gear 1 to rotate slowly clockwise, gear 2 rotates counterclockwise and drives the elliptical block to rotate counterclockwise through the rotating rod, so that the whole equipment is moved to the required position, making the equipment transfer more convenient and quick, and reducing the labor of the staff.

[0009] Furthermore, a mounting base is fixedly connected to the bottom of the reciprocating vacuum pump body, and the bottom of the mounting base is fixedly connected to the top of the moving seat by bolts. A motor 1 is arranged on the right side of the reciprocating vacuum pump body, and a mounting frame is fixedly connected to the bottom of the motor 1 by bolts, and the bottom of the mounting frame is fixedly connected to the top of the moving seat.

A threaded block is fixedly connected to the top of the limit block, and a nut is threadedly connected to the outer surface of the threaded block. An adjustment component is set, specifically, a wrench is used to rotate the nut counterclockwise to move the nut away from the top of the fixed seat, thereby releasing the fixation of the movable seat, and then the movable seat is pushed or pulled to fine-tune the position of the reciprocating vacuum pump body, so that the reciprocating vacuum pump body can be installed at a suitable position of the processing equipment without affecting other work during pharmaceutical preparation.

[0011] Furthermore, a gear one is fixedly connected to the right output end of the motor two, and two rotating rods are arranged above the lifting seat. The surfaces of the two rotating rods have the same structure. The left and right sides of the rotating rods are both rotatably connected to the moving seat.

A gear two is arranged on the left side of the elliptical block on the left side, and a circular hole is opened at the central axis of the gear two. The inner wall of the circular hole is fixedly connected to the outer surface of the rotating rod. When the motor two is started to drive the gear one to rotate slowly counterclockwise, the gear two drives the rotating rod and the elliptical block to rotate in the opposite direction, so that the protruding position of the elliptical block is away from the top of the lifting seat. At this time, the whole equipment will slowly move downward by its own gravity, and the placement can be completed when the bottom of the placement base contacts the ground.

[0012] Furthermore, limiting holes are provided at the four corners of the top of the lifting seat, the inner walls of the four limiting holes are slidably connected to limiting rods, the bottoms of the four limiting rods are fixedly connected to the bottom of the inner wall of the cavity, and the lifting seat will slide on the limiting rods when moving, making the lifting seat more stable when moving and avoiding deviation.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model sets a lifting seat, specifically, starts motor 2 to drive gear 1 to rotate slowly clockwise, then gear 2 rotates counterclockwise and drives the elliptical block to rotate counterclockwise through the rotating rod. Since the bottom of the universal wheel is in contact with the ground, the lifting seat will not move downward at this time, then the fixed seat is lifted to place the base off the ground, and the whole equipment can be moved to the required position, making the equipment transfer more convenient and quick, reducing the labor of the staff.

[0016] 2. The utility model sets a movable seat, specifically, uses a wrench to rotate the nut counterclockwise to move the nut away from the top of the fixed seat, releases the fixation of the movable seat, and then pushes or pulls the movable seat to fine-tune the position of the reciprocating vacuum pump body, so that the reciprocating vacuum pump body can be installed at a suitable position of the processing equipment without affecting other work during pharmaceutical preparation.
