Description

Self-cleaning rotary valve improved structure

The present invention relates to a rotary valve structure, in particular to a material that can be viscous and accumulated in the rotor by means of rotation and scraping, and avoids a decrease in the capacity of the rotary valve caused by the accumulation.

Generally, the granular material or the dry powder material can be stored in a barrel before being processed into a product. To use these materials, the material can be introduced into a rotary valve having a rotor with a groove on the surface of the rotor to receive the material. When the rotor rotates to a certain angle, the material in the groove can fall into the other device.

For granular materials or dry powder materials, such materials do not stick to the grooves of the rotor, but if the viscous material is placed in the groove and then poured out, some materials will inevitably fail. Smoothly disengage from the groove, so the volume or quality of the material will be misaligned the next time the material is contained.

In order to solve the problem of adhering viscous substances inside the groove, a scraping assembly may be disposed on one side of the rotor, the scraping assembly having a single cutting plate or a double squeegee. In general, a single scraper scraping assembly is used, which in turn corresponds to each groove of the rotor surface one by one, such that the speed of the scraper is too fast and vibration is easily generated. When using a scraper assembly with a double scraper, when one scraper is used to scrape the viscous material, the other inactive scraper often moves to the viscous material that has been scraped off, thereby adhering the viscous material to Inside the body.

The purpose of the present invention is to provide an improved structure of a self-cleaning rotary valve which has the effect of reducing the vibration generated during the turning movement and facilitating viewing of the wear of the blade.

In order to achieve the above object and effect, the rotary valve disclosed in the present invention comprises a body; a rotor is disposed in the body, and the rotor surface has a plurality of receiving grooves; a first rotating shaft is coupled to the rotor, and the first The rotating shaft is used to drive the rotor to rotate; a scraping plate assembly is coupled to a longitudinal surface of a second rotating shaft; and a gear set is coupled to the first rotating shaft and the second rotating shaft, respectively. The gear set is rotated to drive the squeegee set and the rotor to rotate, and the long squeegee is transferred into the receiving groove of the rotor surface to scrape off the viscous material; further, the long squeegee pair Each of the accommodating grooves of the surface of the rotor is cyclically entered into each of the accommodating grooves one by one in a jump interval.

The preferred embodiments are set forth below with reference to the purpose and function of the present invention.

The third figure is a schematic diagram of the combination of the rotor, the scraper set and the gear set of the present invention.

Figure 4 is a schematic diagram of the use of this creation.

Figure 5 is a schematic view of the structure of another rotor of the present invention.

Please refer to Figure 1, the creation of a body (10) has a view on the surface. An opening (12) and a cover (14) are used to close the viewing opening (12). Next, the body (10) has an inlet (16). A further first rotating shaft (20) and a second rotating shaft (30) are placed on the body (10).

Referring to FIG. 2, a rotor (22) is disposed in the body (not shown), and the surface of the rotor (22) has a plurality of receiving grooves (24); the first rotating shaft (20) is coupled to the rotor. (22), and the first rotating shaft (20) is used to drive the rotor (22) to rotate. The other scraper set (32) is a long scraper (34) coupled to the second rotating shaft (30), and the long scraping plate (34) is located on the axial surface of the second rotating shaft (30), in addition to the long scraping The plate (34) is housed within the body (not shown).

Referring to Figure 3, a gear set (40) includes a drive gear (42) and a driven gear (44). The driving gear (42) is coupled to one end of the first rotating shaft (20), the driven gear (44) is coupled to one end of the second rotating shaft (30), and the driving gear (42) engages the slave gear Moving gear (44). The first rotating shaft (20) and the rotor (22) are rotated, and the torque is transmitted by the gear set (40), thereby rotating the second rotating shaft (30) and the long scraping plate (34). The above-described driving gear (42) and the driven gear (44) may be selected from the helical gear or the helical gear, and are shown as helical gears. The use of the aforementioned gear type can make the gearing between the gears accurate and the transmission smoother, effectively reducing vibration and noise.

Referring again to Figure 1, the viewing opening (12) of the body (10) is for opposing the rotor (not shown) and the long screed (34). After the cover (14) is opened, the user can conveniently view the wear of the long squeegee (34) or replace the long squeegee (34).

As can be seen from Fig. 3, the drive gear (42) and the driven gear (44) of the gear set (40) can be set to have a predetermined gear ratio. Referring to Fig. 4, the receiving recesses (24) on the surface of the rotor (22) may be five and are designated as (241), (242), (243), (244) and (245), respectively. Therefore, the long scraper (34) can be made to the surface of the rotor (22) at a predetermined gear ratio. The groove (24) is inserted into each of the accommodating grooves (24) one by one in the form of an arithmetic progression with a tolerance of more than one to scrape the viscous material. For example, after the long squeegee (34) finishes scraping the viscous material inside the accommodating recess (241), the long squeegee (34) does not immediately enter the accommodating recess (242), and the accommodating recess When the groove (243) is rotated to the position to be scraped, the long squeegee (34) can enter the accommodating recess (243) for the scraping operation. Similarly, the long squeegee (34) then skips the accommodating recess (244) and scrapes the accommodating recess (245). The long scraper (34) performs the scraping action again to accommodate the recess (242), and the accommodating recess (244) after the interval, and then repeat the previous sequence. In other words, the long scraper (34) is scraped in the order of 1-3-5-2-4 and then repeated. Therefore, for each of the accommodating grooves (241) to (245), the long squeegees (34) are cyclically entered into the accommodating grooves one by one in a hopping interval. In the above description, the long squeegee (34) forms a jump interval for each of the accommodating recesses (24) in a one-to-one interval, and the interval between the gear teeth of the gear set (not shown) can also be formed as an interval. Two or three jump interval forms. In other words, the long scraper (34) scrapes the receiving groove (24) in the order of 1-4-2-5-3 and then repeats.

It should be noted that the long squeegee (34) forms a jump interval for the accommodating recess (24), and the rotational speed of the long squeegee (34) can be reduced, plus a single long squeegee (34) It does not move to the viscous material that has been scraped off, so it can not only effectively reduce the vibration of the whole rotary valve, but also make the inside of the rotary valve relatively clean.

Referring to FIG. 5, the rotor (22) surface of the present invention may have eight receiving grooves (24), and the long scraping plate (34) has a scraping order of 1 for each of the receiving grooves (24). -4-7-2-5-8-3-6, then repeat. Or choose another type of jump interval.

The above embodiments are merely illustrative of the techniques of the present invention and their effects, and are not intended to limit the present invention. Anyone who is familiar with this technology can modify and change the above embodiments without violating the technical principles and spirit of this creation. Therefore, the scope of protection of this creation is The scope of the patent application is as follows.
