Description

Technical Field

[0001] This utility model belongs to the technical field of recycling devices, and in particular relates to an organic acid melt recycling device. Background Technology

[0002] Traditional organic acids (such as succinic acid products) leave a lot of unused residue after melting, which is very wasteful to discharge directly. Therefore, the recycling device will filter the residue at the same time when recycling it.

[0003] However, the existing technology of recycling devices mostly adopts a horizontally arranged filter screen design. When processing succinic acid melt with a certain viscosity or easy crystallization, this structure is very prone to material accumulation, which leads to rapid clogging of the filter screen surface, seriously affecting the filtration efficiency and equipment operation stability. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] This utility model provides an organic acid melt recovery device, comprising:

[0006] A recycling bin, the top of which is provided with a feed pipe that communicates with the inside of the recycling bin, and the inside of the recycling bin is provided with a filtration mechanism;

[0007] The filtration mechanism includes an arched filter screen fixedly installed inside the recycling bin, with the highest point of the arched filter screen corresponding to the position below the feed pipe;

[0008] The filtration mechanism also includes detachable receiving filters on both sides of the arched filter screen, which are connected to the ends of the arched filter screen to form a continuous filtration surface.

[0009] As a preferred embodiment of the above technical solution, the receiving filter is U-shaped and has a fixing block at its top. Fixing seats are provided on opposite side walls inside the recycling bin, and grooves are provided on both the fixing seats and the side walls. The grooves cooperate to form a slot for the receiving filter to be embedded.

[0010] As a preferred embodiment of the above technical solution, a clamping plate is movably arranged laterally on the inner side of the fixed base near the fixed block, and a spring is provided between the clamping plate and the fixed base to connect the two. A top block that can move laterally is also provided through the side wall of the recycling box at the position corresponding to the receiving of the filter screen.

[0011] As a preferred embodiment of the above technical solution, the side wall of the recycling bin is provided with an insertion hole, and the lower horizontal section of the L-shaped top block is inserted into the insertion hole. The outer side wall of the recycling bin is also provided with a horizontal fixing post, the upper vertical section of the L-shaped top block is sleeved on the outside of the fixing post, and a spring connecting the outer side wall of the recycling bin and the L-shaped top block is also sleeved on the outside of the fixing post.

[0012] As a preferred embodiment of the above technical solution, the recycling bin is hinged to a door on its front side.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting an arched filter screen with an upward protrusion in the middle, the organic acid melt is diverted along both sides of the curved surface under the action of gravity and fluidity, avoiding the material from accumulating directly in a single position, thereby effectively preventing the filter screen from clogging. The arched filter screen and the U-shaped receiving filter screens that can be detached on both sides form a continuous filtration structure, which can effectively intercept and collect impurity particles.

[0015] (2) The present invention has a receiving filter screen with a slot-type detachable installation structure and a box door opening method, which makes it easy for operators to quickly take out the filter screen for cleaning or replacement, greatly improving the equipment maintenance efficiency and reducing production interruptions caused by cleaning the filter screen.

[0016] (3) This utility model uses a cleaning mechanism composed of an L-shaped top block, a fixed column, and a spring to trigger a vibration cleaning action, thereby effectively removing impurities attached to the surface of the arched filter screen. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the recycling device in the embodiment;

[0024] This device includes a recycling bin 10, with a door 11 hinged to the front side of the recycling bin 10. The top and bottom of the recycling bin 10 are respectively provided with an inlet pipe 12 and an outlet pipe 13 that communicate with the inside of the recycling bin 10.

[0025] The recycling bin 10 is equipped with a filter mechanism.

[0026] The recycling bin 10 is made of corrosion-resistant material, which can resist the corrosion of succinic acid. The filtration mechanism in the recycling bin 10 separates impurities, unreacted raw materials or other insoluble particles in the succinic acid product melt. The bin door 11 is provided for easy opening, maintenance or replacement of the filtration mechanism. Both the feed pipe 12 and the discharge pipe 13 are equipped with valves.

[0027] like Figure 2 , Figure 3 As shown, Figure 2 The diagram shown is a partial structural diagram of the inside of the recycling bin in the embodiment; Figure 3 What is shown is Figure 2 Enlarged schematic diagram of the structure at point A in the diagram;

[0028] The filtration mechanism includes an arched filter screen 20 fixedly installed inside the recycling bin 10, with the highest point of the arched filter screen 20 corresponding to the position below the feed pipe 12;

[0029] The filtration mechanism also includes receiving filters 30 that are detachably disposed on both sides of the arched filter screen 20, and the receiving filters 30 are connected to the ends of the arched filter screen 20.

[0030] The succinic acid product melt enters the recovery box 10 through the feed pipe 12 and is filtered by the arched filter screen 20. Larger particles of impurities eventually fall into the receiving filter screens 30 on both sides.

[0031] Specifically, the arched filter screen 20 is fixedly connected to the inner rear wall of the recovery box 10, forming an arch (with the middle part protruding upwards). Its highest point corresponds exactly to the bottom of the feed pipe 12, ensuring that the molten succinic acid product falls directly into the middle. Its curved structure allows the molten material to flow to both sides, improving filtration efficiency and reducing the risk of clogging, because the molten material will not directly and vertically accumulate at one point.

[0032] The two ends of the receiving filter screen 30 and the arched filter screen 20 are tightly connected to form a continuous filter surface, and receive the molten material and some smaller particulate impurities that slide down from the arched filter screen 20. As a secondary filtration structure, it further removes fine impurities. The detachable design allows it to be disassembled for cleaning or replacement periodically, which is convenient for maintenance.

[0033] The receiving filter 30 is U-shaped, and a fixing block 31 is provided at its top. Fixing seats 41 are provided on the opposite side walls inside the recycling bin 10. The fixing seats 41 and the side walls are provided with grooves, and the grooves cooperate to form a slot 42 for the receiving filter 30 to be inserted.

[0034] After the fixing base 41 is aligned with the groove on the side wall, a space for the receiving filter 30 to be embedded is formed—the slot 42. The fixing block 31 serves as a limiting point, which facilitates the cooperation with the slot 42 structure. After opening the box door 11, the receiving filter 30 is pushed from the front into the recycling box 10, so that the receiving filter 30 can be embedded in the slot 42 and a stable installation can be achieved.

[0035] A clamping plate 51 is movably arranged laterally on the inner side of the fixed base 41 near the fixed block 31. A spring 52 is provided between the clamping plate 51 and the fixed base 41 to connect the two. A top block 54 that can move laterally is also provided on the side wall of the recycling box 10 at the position corresponding to the position of receiving the filter screen 30.

[0036] The clamping plate 51 is tightly attached to the receiving filter screen 30 under the action of the spring 52, and is clamped. By applying external force to the top block 54, it can resist and knock the receiving filter screen 30, thereby indirectly resisting and knocking the arched filter screen 20. The vibration loosens and falls off the impurities attached to the surface of the arched filter screen 20, which further prevents the arched filter screen 20 from clogging.

[0037] The recycling bin 10 has an insertion hole on its side wall. The lower horizontal section of the L-shaped top block 54 is inserted into the insertion hole. The outer side wall of the recycling bin 10 is also provided with a horizontal fixing post 53. The upper vertical section of the L-shaped top block 54 is sleeved on the outside of the fixing post 53. The outside of the fixing post 53 is also sleeved with a spring 55 that connects the outer side wall of the recycling bin 10 and the L-shaped top block 54.

[0038] Under normal conditions, spring 55 keeps the L-shaped top block 54 in its original position, and the top block 54 does not contact the receiving filter screen 30, so the filtration mechanism operates normally. By applying intermittent external force to the top block 54, spring 55 is compressed, and the lower horizontal section of the top block 54 approaches and impacts the receiving filter screen 30, thereby achieving the effect of impacting and striking the receiving filter screen 30.

[0039] Working principle: Under normal operation: The succinic acid product melt enters the recovery box 10 through the feed pipe 12. First, it is intercepted by the arched filter screen 20 for larger particles of impurities. The fine impurities continue to flow to the receiving filter screens 30 on both sides for secondary filtration. The filtered material is discharged through the discharge pipe 13.

[0040] Unblocking operation procedure: Apply intermittent external force to the top block 54 to compress the second spring 55. The top block 54 moves inward against the resistance of the second spring 55, and its lower horizontal section approaches and intermittently impacts the receiving filter screen 30. The vibration generated by the impact is transmitted to the arched filter screen 20 through the receiving filter screen 30, causing the impurities attached to its surface to loosen and fall off.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
