It is a vacuum dust removal device that can be assembled on a base, occupies a small volume and has a simple structure.

[0003] In the early days, the vacuum system filters of toilet paper machines were generally based on basket filters. The basket filter has a simple structure, but the dust removal effect is poor and it is easy to clog, resulting in excessive pressure difference between the front and rear, which seriously affects production. In addition, due to the problem of filtration accuracy, paper dust can easily enter the vacuum pump, causing the vacuum pump impeller to become clogged. Therefore, it is necessary to design a dust collector with higher filtration accuracy and smaller footprint for use in the dust removal process of toilet paper rolls. Utility Model Content

[0004] In response to the deficiencies in the existing technology, the utility model develops a convenient and efficient dust collector for a papermaking toilet roll equipment system, which can effectively prevent paper scraps from entering the air outlet and causing blockage of the vacuum pump impeller. At the same time, by setting an anti-surge pipe and an air supply valve, it can prevent the occurrence of surge and improve working stability.

[0006] Preferably, pressure gauges are provided at both the air inlet pipe and the air outlet pipe.

[0007] Preferably, a back-blowing port is provided on the shell at the air outlet pipe, the back-blowing port is connected to the air outlet pipe, and a valve is provided on the back-blowing port.

[0008] Preferably, the shell is provided with an array of reinforcing ribs.

[0014] The effects provided in the content of the utility model are only the effects of the embodiments, rather than all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0015] 1. By using dust bags instead of basket filters, the filtration accuracy is improved, which can effectively prevent paper scraps and fine dust from entering the vacuum pump and causing blockage of the vacuum pump impeller, thereby reducing maintenance costs;

[0016] 2. By setting the backflush port, it is more convenient to backflush the paper scraps and dust adsorbed on the dust bag, which is conducive to maintaining a stable negative pressure;

[0017] 3. By setting up an anti-surge pipe and an air supply valve, surge caused by insufficient air intake of the vacuum pump can be prevented, thereby improving operational stability;

[0028] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0029] Example 1

[0030] See also Figures 1 to 5 A convenient and efficient dust collector for a papermaking and toilet roll equipment system includes a shell 1, an air inlet pipe, an air outlet pipe, a dust bag 6 and a drawer 9. The air inlet pipe and the air outlet pipe are arranged on the shell 1, and the air inlet pipe and the air outlet pipe are connected with a flange 5. The dust bag 6 is arranged inside the shell 1. The dust bag 6 is a single-sided closed structure. The open side of the dust bag 6 is connected to the air outlet pipe, and the drawer 9 is slidably connected to the shell 1 near the bottom.

[0031] like Figures 1 to 3 As shown, pressure gauges 4 are provided at both the air inlet pipe and the air outlet pipe.

[0032] like Figure 2 and Figure 3 As shown, a back-blowing port 7 is provided on the shell 1 at the air outlet pipe, the back-blowing port 7 is connected to the air outlet pipe, and a valve is provided on the back-blowing port 7.

[0033] like Figure 1 、 Figure 2 and Figure 4 As shown, the shell 1 is provided with reinforcing ribs 11 in an array.

[0034] like Figure 2 and Figure 3 As shown, the shell 1 is provided with an anti-surge pipe 8, and the anti-surge pipe 8 is provided with an air supply valve. The interior of the air supply valve is a series structure of a one-way valve and a pressure relief valve. When the pressure is too high, the air supply valve will automatically open to prevent surge from occurring.

[0035] like Figure 1 and Figure 4 As shown, the dust removal bags 6 are arranged in an array.

[0036] like Figure 3 As shown, the drawer 9 is provided with a handle 91 .

[0037] like Figures 1 to 3 As shown, an observation window 10 is provided on the housing 1 .

[0038] like Figure 5As shown, a keel support 61 is provided inside the dust removal belt.

[0039] How it works

[0040] The utility model adopts a dust bag 6 to replace the traditional basket filter, which greatly improves the filtering accuracy. After the dust-laden gas generated by the papermaking toilet roll equipment system enters the dust collector housing 1 from the air inlet pipe, the air flow flows through the dust bag 6. The dust bag 6 can effectively intercept paper scraps and fine dust, preventing them from entering the vacuum pump, thereby avoiding clogging of the vacuum pump impeller and reducing maintenance costs. A backflush port 7 is provided on the housing 1 at the outlet pipe. When too much paper scraps and dust adsorbed on the dust bag 6 affect the filtering effect, the valve on the backflush port 7 can be opened to connect the blowing device. At this time, high-pressure gas enters the outlet pipe from the backflush port 7, and then blows in the opposite direction to the dust bag 6, blowing off the paper scraps and dust attached to the dust bag 6, thereby restoring the filtering performance of the dust bag 6 and helping to maintain the negative pressure stability of the system. An anti-surge pipe 8 is provided on the housing 1, and the air supply valve on the pipe is a series structure of a one-way valve and a pressure relief valve. When the vacuum pump's air intake is insufficient, causing the pressure inside the shell 1 to change, if the pressure is too high, the air supply valve will automatically open. By replenishing gas into the shell 1, surge caused by insufficient air intake is prevented, ensuring the stability of the equipment operation. The reinforcement ribs 11 arranged in an array on the shell 1 can effectively enhance the strength of the shell 1, resist long-term negative pressure, prevent the shell 1 from deformation, and extend the service life of the dust collector. The shell 1 is slidably connected to a retractable drawer 9 near the bottom. The paper scraps and dust intercepted by the dust bag 6 fall into the drawer 9 under the action of gravity. When cleaning, you only need to pull the handle 91 on the drawer 9 to easily clean out the collected paper scraps and dust, which greatly simplifies the cleaning work. The observation window 10 provided on the shell 1 allows the operator to observe the adhesion of paper scraps and dust on the internal dust bag 6 in a timely manner, so that regular cleaning can be carried out, thereby improving the convenience of maintenance work. A keel support 61 is provided inside the dust bag 6. Under the action of negative pressure, the keel support 61 can prevent the outer surface of the dust bag 6 from being flattened, ensuring that the dust bag 6 always maintains a good filtering shape and avoids a reduction in filtering efficiency.

On the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
