Description

Technical Field

[0001] This utility model relates to raw material filtration equipment, and more specifically, to adhesive filtration equipment. Background Technology

[0002] Wood glue is a type of adhesive used to bond wood. The production of wood glue usually involves pouring the raw materials into a reactor for mixing and stirring. After the process is completed, the glue is poured into wood glue barrels through a delivery pipeline.

[0003] During the production process, some solid raw materials remain, which are carried into the wood glue drum along with the glue, affecting the quality of the glue. To avoid this, existing technology installs a filtration device in the conveying pipeline. The filtration device includes a filter drum, a lid, and a sieve drum installed inside the filter drum for filtering the glue. A filter screen is fitted on the outer peripheral wall of the sieve drum. The sieve drum includes a cylindrical drum body and a fixing ring fixed to the outer edge of the drum body opening. Several through holes are opened on the outer peripheral wall of the drum body for the wood glue to pass through. Several fixing rings are arranged along the height direction of the sieve drum. A bolt and a retaining ring are detachably connected to a pressure ring. The pressure ring has several round holes for the fixing bolt to pass through. The screen also has perforations. By passing the fixing bolt through the perforations on the screen, and then passing the round holes on the pressure ring through the fixing bolt, the pressure ring is finally screwed into the fixing bolt with a nut to complete the fixing of the pressure ring and the retaining ring. The side wall of the filter barrel has an inlet, and the bottom wall of the filter barrel has an outlet. Wood glue enters the filter barrel from the inlet, then passes through the filter screen and enters the screen barrel through the through hole. Finally, the opening of the screen barrel leads to the outlet, where it is filled into the wood glue bucket.

[0004] To ensure the pressure ring is fixed to the screen, a large number of fixing bolts are usually installed, which means that many nuts need to be screwed in to complete the process of fixing the pressure ring to the screen, making the process of fixing the screen quite cumbersome.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide glue filtration equipment.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a glue filtration device, including a sieve barrel, the sieve barrel including a barrel body and a fixing ring fixed to one end of the barrel body, a filter screen being provided on the outer sleeve of the barrel body, a pressure ring for fixing the filter screen being detachably connected to the barrel body, a plurality of clamping blocks for fixing the pressure ring being detachably connected to the outer edge of the fixing ring, a plurality of grooves I being provided on the top surface of the pressure ring, a plurality of grooves II being provided on the bottom surface of the fixing ring, two snap-fit ​​parts being formed on the clamping blocks being able to be embedded in the grooves I and II, the clamping blocks including a bent part and two flat parts being integrally formed at both ends of the bent part, the two snap-fit ​​parts being formed on the two flat parts respectively, and a slot for disassembling the clamping block being provided at the end of the snap-fit ​​part away from the bent part.

[0008] The present invention is further configured such that: a ring groove is formed on the fixing ring, and a ring protrusion is formed on the pressing ring for pressing one end of the filter screen against the side wall of the ring groove.

[0009] The present invention is further configured such that: the cross-section of the annular protrusion is trapezoidal, and the width of the end of the annular protrusion away from the pressure ring is smaller than the width of the connection between the annular protrusion and the pressure ring.

[0010] The present invention is further configured such that: a recess and a convex strip on the same side as the ring protrusion are stamped on the pressure ring, the convex strip is arranged along the radial direction of the pressure ring, and a groove is opened on the fixing ring. When the convex strip is embedded in the groove, the projection surfaces of groove one and groove two coincide.

[0011] The present invention is further configured such that there is one and only one protrusion.

[0012] The present invention is further configured such that the thickness at the connection between the flat part and the bent part is greater than the thickness at the connection between the flat part and the snap-in part.

[0013] The present invention is further configured such that the end of the annular protrusion away from the pressure ring has a rounded corner.

[0014] The present invention is further configured such that the clamping block is made of 201 stainless steel.

[0015] In summary, this utility model has the following beneficial effects: When installing the filter screen, people can first put the filter screen on the outer circumferential wall of the barrel, then pass the pressure ring through the barrel and press it on the fixing ring. After aligning the centers of slot one and slot two, the clamping block is inserted into slot one and slot two. The clamping block abuts against the inner walls of slot one and slot two respectively, so that the clamping block can better fix the pressure ring and the fixing ring, thereby allowing the pressure ring to better press one end of the filter screen against the fixing ring. The above settings allow people to complete the fixing of the filter screen by simply inserting the clamping block into slot one and slot two, making the filter screen fixing process more convenient.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Glue filtration equipment, such as Figure 1 and Figure 2As shown, the device includes a sieve barrel, which comprises a barrel body 1 and a fixing ring 2 welded to one end of the barrel body 1. A filter screen 3 is fitted onto the outer peripheral wall of the barrel body 1. A pressure ring 4 for fixing the filter screen 3 is detachably connected to the barrel body 1. Several clamping blocks for fixing the pressure ring 4 are detachably connected to the outer edge of the fixing ring 2. The clamping blocks are generally U-shaped. Several grooves 5 are formed on the upper top surface of the pressure ring 4, and the grooves 5 are arranged in a circular array along the circumference of the pressure ring 4. Several grooves 6 are formed on the lower bottom surface of the fixing ring 2, and the grooves 6 are arranged in a circular array along the circumference of the fixing ring 2. The clamping blocks form The clamping block has two locking parts 14 that can be respectively embedded in slot 5 and slot 6. The clamping block includes a bent part 7 and two flat parts 8 integrally formed at both ends of the bent part 7. The two locking parts 14 are respectively formed on the two flat parts 8. The end of the locking part 14 away from the bent part 7 is provided with a slot 15 for disassembling the clamping block. When one flat part 8 on the same clamping block is embedded in slot 5, the other flat part 8 can be embedded in slot 6. When installing the filter screen 3, people can first put the filter screen 3 on the outer peripheral wall of the barrel 1, and then pass the pressure ring 4 through the barrel 1 and press it on the fixed part. On ring 2, after aligning the centers of slot 5 and slot 6, insert the clamping blocks into slots 5 and 6, so that one locking part 14 is embedded in slot 5 and the other locking part 14 is embedded in slot 6. At this time, when several slots 5 and several slots 6 are all embedded by their corresponding locking parts 14, the fixing ring 2 and the pressure ring 4 are completely fixed by several clamping blocks, so that the pressure ring 4 can better press one end of the filter screen 3 against the fixing ring 2. The above arrangement allows people to fix the filter screen 3 by the pressure ring 4 and the fixing ring 2 simply by inserting the clamping blocks into slots 5 and 6. The process of fixing the filter screen 3 is relatively convenient. After filtration, when it is necessary to disassemble the filter screen 3, people can put their hands into the slot 15 and apply force to make the two locking parts 14 disengage from the slot 1 5 and slot 2 6 respectively. Then, the flat part 8 is removed from the pressure ring 4 and the fixing ring 2. At this time, the limiting of the pressure block on the pressure ring 4 and the fixing ring 2 disappears, and people can remove the pressure ring 4 from the fixing ring 2. Then the filter screen 3 can be removed from the fixing ring 2. The opening of the slot 15 provides people with a good point of force to complete the disassembly of the pressure block, thus making the subsequent disassembly of the filter screen 3 more convenient.

[0023] like Figures 2 to 4As shown, the fixing ring 2 has an annular groove 9, and the pressure ring 4 has an annular protrusion 10 for pressing one end of the filter screen 3 against the side wall of the annular groove 9. When the clamping block fixes the fixing ring 2 and the pressure ring 4, the annular protrusion 10 can effectively press one end of the filter screen 3 against the side wall of the annular groove 9, thereby further ensuring the strength of the fixing ring 2 and the pressure ring 4 in fixing the filter screen 3. When the wood glue is filtered through the filter screen 3, one end of the filter screen 3 is not easy to detach from the fixing ring 2 and the pressure ring 4. The cross-section of the annular protrusion 10 is trapezoidal. The width of the end of the annular protrusion 10 away from the pressure ring 4 is smaller than the width at the connection between the annular protrusion 10 and the pressure ring 4. During the process of the annular protrusion 10 pressing one end of the filter screen 3 into the annular groove 9, the width of the end of the annular protrusion 10 away from the pressure ring 4 is smaller, making it easier for the annular protrusion 10 to be inserted into the annular groove 9. At the same time, compared with the annular protrusion 10 with a rectangular cross-section, the side length of the trapezoidal annular protrusion 10 is shorter. At the end of the annular protrusion 10 that abuts against the filter screen 3, the filter screen 3 is subjected to... During deformation, the annular protrusion 10 can effectively ensure the fixation of the filter screen 3 while also reducing the deformation of the filter screen 3, making the filter screen 3 less prone to breakage. The pressure ring 4 has a recess 11 and a protrusion 12 on the same side as the annular protrusion 10. The protrusion 12 is set along the radial direction of the pressure ring 4 and does not intersect with the annular protrusion 10. The fixing ring 2 has a groove 13. When the protrusion 12 is embedded in the groove 13, the projection surfaces of groove 1 5 and groove 2 6 coincide. When people press the pressure ring 4 onto the fixed ring 2, the recess 11 can be aligned with the groove 13 so that the protrusion 12 is embedded in the groove 13. When the clamping block is subsequently inserted into the groove 5 and the groove 6, the protrusion 12 embedded in the groove 13 makes it difficult for the pressure ring 4 to rotate relative to the fixed ring 2. This eliminates the need for people to spend time preventing the pressure ring 4 from rotating relative to the fixed ring 2, allowing the clamping block to quickly fix the pressure ring 4 and the fixed ring 2.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, there is only one protrusion 12. Setting the number of protrusions 12 to one allows the pressure ring 4 to be set with the protrusion 12 in one stamping. At the same time, fewer stamping positions can better ensure the overall strength of the pressure ring 4. The thickness at the connection between the flat part 8 and the bent part 7 is greater than the thickness at the connection between the flat part 8 and the snap-in part 14. The cross-section of the snap-in part 14 is a right-angled triangle. The inclined surface of the snap-in part 14 is formed at the end of the snap-in part 14 facing away from the bent part 7. During the process of inserting part 14 into slots 5 and 6, the inclined surface on part 14 provides a good guide to the clamping block, allowing part 14 to slide into slots 5 and 6 quickly. This enables people to quickly use the clamping block to fix the fixing ring 2 and the pressure ring 4. When part 14 abuts against the pressure ring 4 and the fixing ring 2, the contact force causes the two flat parts 8 to deform, making the thickness of the connection between the flat part 8 and part 14 thinner, thus making the flat part at that point... 8 can deform relatively easily. After the clamping block is inserted, the stress generated by the deformation is easily concentrated at the connection between the flat part 8 and the bent part 7. The thickness of the connection between the bent part 7 and the flat part 8 is set to be thicker, so that the strength of the connection is higher and the bending resistance is stronger, thus ensuring the strength of the clamping block. The end of the annular protrusion 10 away from the pressure ring 4 is rounded. When the annular protrusion 10 presses the filter screen 3 against the annular groove 9, the rounded corner at the end of the annular protrusion 10 away from the pressure ring 4 makes the contact surface between the annular protrusion 10 and the filter screen 3 smoother. This setting makes the stress on the contact surface between the filter screen 3 and the annular protrusion 10 more dispersed, so that the filter screen 3 is not easily torn. The clamping block is made of 201 stainless steel. 201 stainless steel has the characteristics of high bending strength and good corrosion resistance. The clamping block made of 201 stainless steel can fix the pressure ring 4 and the fixing ring 2 better, and can also adapt to the working environment in the filter barrel, so that the clamping block has a long service life.
