Description

Technical Field

[0001] The invention belongs to the technical field of slag filtering, and in particular relates to an emulsification pump discharge filtering device. Background Art

[0002] The emulsifier pump is a commonly used industrial pump. Its main function is to continuously shear, impact and fold the raw materials under high-speed vortex conditions, so as to mix them and finally form a uniform liquid. Emulsifier pumps are widely used in chemical, food, pharmaceutical and other industries, and play an important role in the production process. In the food industry, some endogenous foreign matter such as fascia and bone residue may remain after the meat raw materials are emulsified in the emulsifier pump. If they are not screened out, it will affect the appearance and quality of the product. The existing solution is to set a filter at the discharge end of the emulsifier pump, but the accumulation of too much fascia and bone residue in the filter will cause the discharge end of the emulsifier pump to be blocked, and the filter needs to be removed frequently for cleaning, and then the filter needs to be installed back to the discharge end of the emulsifier pump. This method is more labor-intensive, and the emulsifier pump needs to be suspended during the cleaning and reinstallation of the filter, which will affect the production efficiency, so it is necessary to make improvements. Summary of the invention

[0004] In order to achieve the above object, the present invention adopts the following technologies:

[0007] Two filter covers are coaxially arranged at the outward ends of the two transverse sections, and a second connecting block is arranged at the inner end of the filter cover close to the opening, and the two second connecting blocks are rotatably connected to the two first connecting blocks respectively;

[0008] The discharge pipe is coaxially arranged at the outward end of a transverse section at the top, the outer diameter of the discharge pipe matches the inner diameter of the transverse section, and the discharge pipe is connected to a pushing mechanism, which is used to drive the discharge pipe to move axially.

[0009] Furthermore, a retaining ring is provided on the inner side of one end of the discharge pipe facing the transverse section, and an annular rubber gasket is provided on one end of the retaining ring facing the transverse section, and the outer diameter of the filter cover matches the inner diameter of the retaining ring.

[0010] Furthermore, a baffle is provided on the inner side of the discharge pipe, and when the transverse section abuts against the rubber gasket, the filter cover abuts against the baffle.

[0011] Furthermore, a pressing mechanism is provided at the top of an upper transverse section, and the telescopic end of the pressing mechanism is connected to a push block, which is used to push the filter cover so that the axial direction of the upper filter cover is the same as the axial direction of the upper transverse section.

[0012] Furthermore, the push block is V-shaped, with its inner side facing the filter cover, and the two inclined surfaces on the inner side of the push block are symmetrically arranged, and the central axis of the upper transverse section is within the symmetry plane of the two inclined surfaces.

[0013] Furthermore, the rotating mechanism includes a cylinder, a gear ring, and a rack. The gear ring is sleeved on the outside of the feed pipe. The feed pipe is rotatably connected in a connecting ring. The connecting ring is fixed to a fixed frame. The gear ring is meshingly connected to the rack. One end of the rack is connected to the telescopic end of the cylinder, and the cylinder is fixed to the fixed frame.

[0021] 3. The fixed frame and connecting ring can limit the rotation direction of the feed pipe, and the limit ring and the slip ring can make the U-shaped tube rotate only in the slip ring, which can avoid the tilt of the transverse section after being thrust by the discharge pipe, and improve the stability of the device during operation.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] The present application embodiment provides an emulsification pump discharge filtering device, such as Figure 1-Figure 9 As shown, it includes a U-shaped tube 1, a filter cover 3, a discharge pipe 4, etc.

[0034] Specifically, the U-shaped tube 1 includes a vertical section 101 and a transverse section 102 connected to both ends of the vertical section 101. The end of the vertical section 101 away from the transverse section 102 is connected to the feed pipe 2. The two transverse sections 102 are symmetrical with respect to the feed pipe 2. A pair of control valves 103 are provided on the vertical section 101. The pair of control valves 103 are respectively located on both sides of the feed pipe 2. The feed pipe 2 is connected to a rotating mechanism. The rotating mechanism is used to drive the feed pipe 2 to rotate around the axial direction of the feed pipe 2. The top of the inner side of the outward end of the upper transverse section 102 and the lower transverse section A first connecting block 1021 is provided at the bottom of the inner side of the outward end of 102; there are two filter covers 3, which are coaxially arranged at the outward ends of the two transverse sections 102, and a second connecting block 301 is provided at the inner end of the filter cover 3 close to the opening, and the two second connecting blocks 301 are rotatably connected to the two first connecting blocks 1021 respectively; a discharge pipe 4 is coaxially arranged at the outward end of an upper transverse section 102, and the outer diameter of the discharge pipe 4 matches the inner diameter of the transverse section 102, and the discharge pipe 4 is connected to a pushing mechanism 5, which is used to drive the discharge pipe 4 to move axially.

[0035] In actual use, the push mechanism 5 is controlled to drive the discharge pipe 4 to move toward the U-shaped tube 1, so that the upper transverse section 102 of the U-shaped tube 1 is connected to the discharge pipe 4, and then the upper control valve 103 is controlled to open and the lower control valve 103 is controlled to close. At this time, the filter cover 3 at the top is in the discharge pipe 4, which can prevent the fascia and bone residues remaining after the emulsification pump emulsifies from entering the discharge pipe 4. When the filter cover 3 is full of residues, both control valves 103 are controlled to be closed, and then the push mechanism 5 is controlled to drive the discharge pipe 4 to retract, and then the rotation mechanism is controlled to drive the feed pipe 2 and the U-shaped tube 1 to rotate 180 degrees, so that the lower transverse section 102 is rotated to align with the discharge pipe 4, and the filter cover 3 rotated to the top will rotate downward due to gravity to the same axial direction as the discharge pipe 4. At this time, the push mechanism 5 is controlled to drive the discharge pipe 4 to move toward the U-shaped tube 1 to connect the transverse section 102 with the discharge pipe 4, so as to realize the automatic replacement of the filter cover 3, and then the upper control valve 103 is controlled to open to continue discharging. After the transverse section 102 originally located at the top rotates to the bottom, the filter cover 3 connected thereto will rotate downward by 180 degrees due to its own gravity, so that the opening of the filter cover 3 is no longer covered by the opening of the transverse section 102. At this time, the residue in the filter cover 3 can be flushed out by flushing, and the residue can be prevented from being flushed into the transverse section 102. Specifically, a water pressure sensor can be provided on the feed pipe 2 to determine whether the residue in the filter cover 3 is full. If the water pressure is too high, it is determined that the filter cover is blocked, and the filter cover 3 can be replaced in time in this way.

[0036] Because the filter cover 3 may be subject to the friction of the transverse section 102 during the rotation process and cannot rotate downward 180 degrees due to its own gravity, in one embodiment, refer to Figure 1 , Figure 2 A pressing mechanism 6 is provided on the top of a transverse section 102 at the top, and the telescopic end of the pressing mechanism 6 is connected to a push block 601. The push block 601 is used to push the filter cover 3 at the top, and can push the filter cover 3 at the top downward until its axial direction is the same as the axial direction of the transverse section 102 at the top, so as to prevent the filter cover 3 from being unable to align with the discharge pipe 4. For details, refer to Figure 6 , Figure 7 The push block 601 is V-shaped, with its inner side facing the filter cover 3, and the two inclined surfaces 6011 on the inner side of the push block 601 are symmetrical about a vertical plane, and the central axis of the upper transverse section 102 is in the vertical plane. When the two inclined surfaces 6011 on the inner side of the push block 601 are in contact with the side of the filter cover 3, the axial direction of the filter cover 3 and the transverse section 102 are the same, which can prevent the filter cover 3 from not being pushed to align with the discharge pipe 4.

[0037] Preferably, see Figure 6A first flushing pipe 10 is provided at the outward end of the lower transverse section 102. When the lower filter cover 3 is rotated downward to the maximum, the lower filter cover 3 is within the water spraying range of the first flushing pipe 10. Through this arrangement, the replaced filter cover 3 can be automatically flushed after switching the filter cover 3, further saving labor.

[0038] Preferably, see Figure 6 A second flushing pipe 11 is arranged above the filter cover 3 at the bottom, and the water spraying direction of the second flushing pipe 11 is set downward. When the filter cover 3 rotates to the bottom and cannot rotate 180 degrees downward due to its own gravity due to friction, water is sprayed to the top of the filter cover 3 at the bottom through the second flushing pipe 11, so that the filter cover 3 is forced to rotate downward. For details, refer to Figure 1 A collecting tank 12 is provided below the first flushing pipe 10 for accommodating water discharged from the first flushing pipe 10 and the second flushing pipe 11 and filter residue in the filter cover 3 .

[0039] For details, see Fig. 9 A retaining ring 401 is provided on the inner side of one end of the discharge pipe 4 facing the transverse section 102, and an annular rubber gasket 402 is provided on the end of the retaining ring 401 facing the transverse section 102. The outer diameter of the filter cover 3 matches the inner diameter of the retaining ring 401. When the pushing mechanism 5 drives the discharge pipe 4 to move toward the U-shaped tube 1, the transverse section 102 at the top enters the discharge pipe 4 and abuts against the rubber gasket 402, which can improve the sealing of the connection. More specifically, a retaining plate 403 is provided on the inner side of the discharge pipe 4. When the transverse section 102 abuts against the rubber gasket 402, the filter cover 3 abuts against the retaining plate 403. By providing the retaining plate 403, it can be prevented that the liquid discharged from the transverse section 102 generates a large impact force on the filter cover 3, causing the filter cover 3 to deform.

[0040] For details, see Figure 6 , Figure 8 The rotating mechanism includes a cylinder 7, a ring gear 701, and a rack 702. The ring gear 701 is sleeved on the outside of the feed pipe 2. The feed pipe 2 is rotatably connected to a connecting ring 201, so that the feed pipe 2 can only rotate in the connecting ring 201. The connecting ring 201 is fixed to a fixed frame 703. The ring gear 701 is meshed and connected with the rack 702. One end of the rack 702 is connected to the telescopic end of the cylinder 7. The cylinder 7 is fixed to the fixed frame 703. When the telescopic end of the cylinder 7 is fully retracted, a transverse section 102 of the U-shaped tube 1 is aligned with the discharge tube 4. When the telescopic end of the cylinder 7 is fully pushed out, the U-shaped tube 1 rotates 180 degrees.

[0041] For details, see Figure 4 , Figure 6, two transverse sections 102 are arranged on the outside and are both sleeved with a limit ring 8, and the outer sides of the limit ring 8 are symmetrically provided with protrusions 801, and the two transverse sections 102 are arranged in a slip ring 9, and the inner side of the slip ring 9 is provided with an annular groove 901, and the two protrusions 801 are slidably arranged in the annular groove 901, and the limit ring 8 is fixed between a pair of support rods 902. Through this arrangement, the transverse section 102 can be prevented from tilting after being thrust by the discharge pipe, and the stability of the device can be improved.

Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
