Description

A rotatable cleaning grate

Technical Field

The utility model relates to the technical field of cleaning equipment, in particular to a rotatable cleaning grate.

Background Art

In the pharmaceutical manufacturing industry, one of the essential components is the hopper. By using the hopper as a container to mix the main material and the auxiliary material, some residual medicine will remain in the hopper after use. At this time, the hopper needs to be cleaned. Because the volume of the hopper is usually large, it will be cleaned manually with a cleaning grate. The cleaning grate is a drainage facility placed at the bottom of the hopper to drain the dirty water from the cleaning hopper.

However, the cleaning bottom grate of the prior art adopts a grille structure and only has a basic drainage function. When cleaning the outside of the hopper, due to its large size, it needs to be cleaned around the circumference by a cleaning machine during manual cleaning. This common cleaning method is not only labor-intensive and reduces work efficiency, but also easily causes inadequate cleaning, affecting subsequent work progress.

As shown in Figures 1 to 3, an embodiment of the utility model is a rotatable cleaning grate, including a grate body 1 and a rotating mechanism for driving the grate body 1 to rotate, the rotating mechanism including a rotating shaft 2 connected to the grate body 1 and a rotating seat 3 adapted to the rotating shaft 2, the rotating shaft 2 is provided with a first step 4 and a second step 5, the inner diameter of the first step 4 is larger than the inner diameter of the second step 5, a first bearing 6 and a second bearing 7 are provided between the rotating shaft 2 and the rotating seat 3, the first bearing 6 is against the radial inner wall of the first step 4, and the second bearing 7 is against the axial inner wall of the second step 5. The utility model helps the hopper to rotate by installing a cleaning grate with a rotating mechanism, thereby eliminating the need for manual use of a cleaning machine to clean around the circumference of the hopper. The cleaning machine only needs to be fixed on one side of the hopper, and the grate body is manually driven to drive the hopper to rotate so that the circumference of the hopper can be fully cleaned. The grate body connected to the rotating shaft rotates with the rotating seat through the first bearing and the second bearing. The first bearing can help the rotating shaft to rotate smoothly, and the second bearing can support and help the rotating shaft to rotate smoothly. The utility model is conducive to convenient and efficient cleaning of the hopper, and realizes economical, environmentally friendly and labor-saving work requirements.

As shown in Fig. 3 to Fig. 5, a water accumulation tray 8 is also included, the bottom of which is mounted on the rotating seat 3, a flow port 9 is provided between the inner edge of the water accumulation tray 8 and the outer edge of the floor grate body 1, the space between the water accumulation tray 8 and the floor grate body 1 forms a water accumulation cavity 10, and a drain pipe 11 is also provided at the bottom of the water accumulation tray 8. Through the above structure, the sewage from the cleaning hopper flows into the water accumulation cavity through the flow port, the water accumulation tray connected to the rotating seat can collect the sewage after cleaning, and the sewage collected in the water accumulation tray is finally discharged through the drain pipe, and the drain pipe can also be connected to the sewage treatment device to purify the sewage, and then enter the cleaning water tank through the water suction pump, so as to realize the function of sewage recycling and meet the social needs of saving and environmental protection.

As shown in Figure 5, the bottom of the water tray 8 near the drain pipe 11 is inclined at an angle of 1 to 1.5° with the horizontal plane. The water tray of this embodiment adopts an inclination angle of 1°, which can promote sewage to flow along the bottom of the water tray to the drain pipe and prevent sewage from accumulating.

As shown in Fig. 5, a support mechanism is provided in the water accumulation chamber 10, and the support mechanism includes a screw rod 12 and an adjustment seat 13 which is sleeved on the screw rod 12. Two locking nuts 14 are threadedly matched on the screw rod 12, and the adjustment seat 13 is located between the two locking nuts 14. The position of the adjustment seat 13 is changed by adjusting the tightness of the two locking nuts 14. A ball 15 is provided on the top of the adjustment seat 13, and a support ring 16 is provided at the bottom of the grate body 1. The bottom of the support ring 16 is in rolling cooperation with the ball 15. Through the above structure, i.e., the support mechanism between the water accumulation tray and the grate body, the height of the adjustment seat is adjusted by the cooperation of the screw rod and the locking nut, and the support ring of the grate body is in rolling cooperation with the ball of the adjustment seat. The support mechanism can both support the grate body and help it rotate.

As shown in Fig. 4, the drain pipe 11 is provided with a drain valve 17 for opening or blocking the drain pipe 11. Through the above structure, the drain valve can control the discharge of sewage and prevent the sewage from rushing down.

As shown in Fig. 4 and Fig. 5, the inner wall of the water accumulation tray 8 is provided with a floating liquid ring 18, one end of which extends to the inside of the water accumulation chamber 10 and the other end extends to the outside of the water accumulation tray 8 and is linked to the drain valve 17. Through the above structure, the floating liquid ring is used to measure the water level of the water accumulation tray. When the drain valve fails or the drain pipe is blocked, or the sewage level reaches a limited height, the floating liquid ring can alarm in time, and the cleaning machine stops cleaning in time to prevent sewage overflow and cause secondary pollution. The floating liquid ring usually refers to a float switch or a liquid level switch.

As shown in Fig. 6, at least two handles 19 are evenly distributed along the circumference of the top of the floor grate body 1. Through the above structure, the handles are convenient for manually driving the floor grate body to rotate, saving manpower.

The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
