[0012] 1. The utility model is a multifunctional integrated auxiliary device for a jet dosing system. It is connected to the upper part of the screw dosing machine's discharge port through a quick-release chuck clamp at the lower end of the barrel. The upper part of the screw dosing machine's feed port is connected to the silo. During the silo loading process, the air in the silo, carrying material dust, enters the auxiliary device after passing through the screw dosing machine.

The utility model is a multifunctional integrated auxiliary device for a jet dosing system, which is connected to the upper part of the screw dosing machine outlet through a quick-release chuck clamp at the lower end of the barrel. The screw dosing machine outlet is connected to an ejector. The ejector is designed based on the principle of a Venturi tube. During operation, a certain amount of air needs to be added from the outside to ensure the normal operation of the ejector. Therefore, during the jet dosing stage, the outside air will enter the barrel through the annular gap and then enter the ejector after passing through the screw dosing machine, thereby replenishing the air in the ejector.

[0014] 3. The utility model is a multifunctional integrated auxiliary device for a jet dosing system. When the ejector has an operating problem and cannot dosing materials normally, the materials will accumulate at the ejector. When the height of the accumulated materials approaches the capacitive proximity switch of the auxiliary device, the dielectric constant between the two poles of the capacitor will change, thereby causing the capacitance value to change.

DETAILED DESCRIPTION

[0027] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-10 As shown, a multifunctional integrated auxiliary device for a jet dosing system includes a hollow barrel body 1, a stainless steel filter element 2 fixed inside the barrel body 1, and a barrel cover 3 quickly connected to the barrel body 1. There is an annular gap 4 between the barrel body 1 and the barrel cover 3. A capacitive proximity switch 5 is fixedly arranged below the stainless steel filter element 2. The capacitive proximity switch 5 is electrically connected to an electrical control cabinet (not shown) through a cable 6.

[0029] Furthermore, a bottom ring 7 is fixedly provided at the upper end of the barrel body 1, and a pressure ring 8 for fixing the stainless steel filter element 2 is provided on the bottom ring 7. The stainless steel filter element 2 includes a hollow filter cartridge 9 and a flanged flange 10 fixedly provided above the hollow filter cartridge 9. The outer diameter of the hollow filter cartridge 9 is the same as the inner diameter of the bottom ring 7. The flanged flange 10 is located on the bottom ring 7. Several studs 11 are vertically provided on the bottom ring 7 around the central axis. Bolt holes 12 matching the studs 11 are provided on the pressure ring 8. The pressure ring 8 is located above the flanged flange 10. A butterfly nut 13 is provided on the stud 22. The butterfly nut 13 fixes the pressure ring 8 and the flanged flange 10 to the bottom ring 7.

[0030] Specifically, the fixing process of the stainless steel filter element 2 is as follows: first, insert the hollow filter cartridge 9 of the stainless steel filter element 2 into the bottom ring 7 into the barrel body 1, and the flange 10 of the stainless steel filter element 2 is just located on the bottom ring 7, and then align the bolt hole 12 of the pressure ring 8 with the stud 11 and insert it, and use the butterfly nut 13 to tighten it with the stud 11 to press the pressure ring 8, thereby fixing the stainless steel filter element 2 between the bottom ring 7 and the pressure ring 8, wherein the butterfly nut 13 is used for tightening to facilitate the operation of the staff.

[0031] Furthermore, the barrel cover 3 includes a barrel cover body 14 and a quick locking pin 15 fixedly arranged on the barrel cover body 14, and a pin hole 16 matching the quick locking pin 15 is provided on the bottom ring 7, and the barrel cover 3 and the barrel body 1 are fixedly connected by the quick locking pin 15 and the pin hole 16.

[0032] After the internal structure of the barrel body 1 is installed, the barrel cover 3 needs to be installed. It is only necessary to insert the quick locking pin 15 on the barrel cover body 14 into the pin hole 16 on the bottom ring 7 of the barrel body 1. The installation structure is simple and easy to operate. The inner diameter of the barrel cover body 14 is set to be larger than the outer diameter of the bottom ring 7, and an annular gap 4 is formed between the inner wall of the barrel cover body 14 and the bottom ring 7. After installation, the annular gap 4 is used to communicate with the outside atmosphere to form an air channel.

[0033] Furthermore, a support column 17 is provided on the barrel cover body 14. The support column 17 is located above the pressure ring 8 and is in contact with the pressure ring 8. When the barrel cover 3 is installed, the support column 17 plays a good supporting role on the barrel cover 3, effectively preventing the barrel cover 3 from sinking and the annular gap 4 from becoming smaller, resulting in a reduction in the air supply area and a reduction in the air supply efficiency. At the same time, the support column 17 plays a certain pressing role on the pressure ring 8, thereby improving the fixing effect of the pressure ring 8 on the stainless steel filter element 2.

[0034] Furthermore, a mounting hole 18 is provided on the bottom ring 7, and a wire sheath 21 is fixedly provided on the mounting hole 18. The cable 6 passes through the wire sheath 21 and is connected to the electrical control cabinet. The wire sheath 21 is mainly provided to provide good protection for the cable 6 and facilitate the bending and laying of the cable 6.

[0035] Furthermore, the lower end of the barrel body 1 is fixedly provided with a quick-release chuck 20 for connecting to the screw dosing machine 19 clamp. The capacitive proximity switch 5 is arranged close to the quick-release chuck 20, which can timely detect abnormal operation of the jet dosing system and issue an alarm signal in time.

[0036] It should be noted that the capacitive proximity switch of the present invention is electrically connected to the electrical control cabinet through a cable, and a corresponding photoelectric alarm is provided on the electrical control cabinet. When the capacitance value of the capacitive proximity switch changes, the photoelectric alarm on the electrical control cabinet is controlled to alarm. This technology is existing technology and will not be repeated here.

[0037] The working process of this utility model is as follows: Figure 11 As shown, the auxiliary device of the present invention is connected above the discharge port of the screw feeder 19 through a quick-release chuck 20 clamp. The feed port of the screw feeder 19 is connected to the silo, and the discharge port of the screw feeder is connected to the ejector.

[0038] During the silo loading stage, due to the pneumatic conveying loading method adopted by the silo, as the powder material in the silo increases, a large amount of air gathered in the silo will be discharged at various non-sealed points of the jet speculation system. Since the powder material has a relatively light specific gravity, when the air in the silo is discharged, the air is also discharged together with the material dust, which will cause serious pollution to the working environment. Therefore, during the silo loading stage, the auxiliary device of the utility model, the air in the silo is entrained with the material dust and enters the auxiliary device after the spiral feeder, and is discharged in the annular gap after being filtered by the stainless steel filter element, thereby playing a good filtering role.

[0039] During the jet addition stage, the auxiliary device mainly plays the role of replenishing air and preventing blockage alarm. Specifically, since the ejector is designed based on the principle of the Venturi tube, a certain amount of air needs to be added from the outside during operation to ensure the normal operation of the ejector. Therefore, during the jet addition stage, the outside air will enter the barrel through the annular gap and then enter the ejector through the spiral feeder to realize air replenishment of the ejector; when the ejector has operational problems and cannot add materials normally, the material will accumulate at the ejector. When the height of the accumulated material is close to the capacitive proximity switch of the auxiliary device, the dielectric constant between the two poles of the capacitor will change, thereby causing the capacitance value to change. The change in capacitance causes the circuit state connected to the sensing surface to change, and then an alarm signal is issued, thereby realizing the alarm function.

[0040] The utility model provides a multifunctional integrated auxiliary device for a jet dosing system, which has three functions of material filtering, ejector air supply and alarm, has a compact structure, integrated functions, and is convenient and reliable to use.

[0041] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
