Description

Technical Field

[0001] This invention belongs to the field of resin tool technology, specifically relating to a resin loading and unloading device and method. Background Technology

[0002] Power plants and chemical plants use a large amount of equipment that requires resin, and the resin needs to be replaced regularly. In the past, this was usually done manually.

[0003] The traditional methods for unloading waste resin have the following disadvantages:

[0004] (1) When the unloading manhole of the equipment is opened, the waste resin will quickly scatter due to gravity, and the scattering speed cannot be controlled. Moreover, the waste resin is very easy to scatter on the ground, which will greatly burden the subsequent ground cleaning work. (2) When the free scattering stage of waste resin ends, some waste resin remains inside the equipment. At this time, it can only be unloaded manually by the on-site operators, which is also a lot of work. In addition, the working environment may be poor due to the limited on-site conditions.

[0005] For loading new resin, traditional loading methods have the following drawbacks:

[0006] (1) The workload is large, with the amount of resin filled inside the equipment ranging from a few cubic meters to tens of cubic meters, and a new barrel of resin weighing several hundred kilograms, all of which increase the burden on operators. (2) The height of the feed manhole is relatively high, which increases the danger to operators. (3) The loading speed cannot be controlled due to the use of the manhole tilting method. (4) The loading is uneven due to the use of the manhole tilting method. Summary of the Invention

[0007] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide a device that can reduce the physical labor of operators, prevent spillage during the unloading of waste resin, and control the filling speed during the filling of new resin.

When open, it is used for the free-fall stage of the waste resin unloading process, allowing the waste resin to directly enter the collection chamber 7; when closed, it is used for the suction stage of the waste resin unloading process, ensuring the sealing of the collection chamber 7.

[0056] The collection chamber outlet 10 is connected to the waste resin tank 19 via a first hose 18. A first ball valve 17 is provided on the collection chamber outlet 10 to control the outflow rate of the waste resin in the collection chamber 7.

[0073] The present invention also provides a waste resin unloading method for a resin loading and unloading device, using an unloading device applied in the free-scattering stage of the waste resin unloading process, comprising the following steps:

[0074] Step 1: The operator loosens the nut on the sealing cap of the unloading manhole 1 to the appropriate time (so that the sealing cap does not fall off and the waste resin does not overflow);

[0075] Step 2: The collection bag 13 is tightly assembled between the unloading manhole 1 and the collection bin inlet 8 using the first fastening airbag 14 and the second fastening airbag 15.

[0076] Step 3: The operator opens the sealing cover of the unloading manhole 1 through the inner extension glove 16 on the collection bag 13. The waste resin falls freely from the unloading manhole 1 into the collection bin 7. During this process, the operator observes the inside of the collection bin 7 through the observation window 11. If the waste resin cannot fall freely, the operator inserts a tool through the auxiliary tool port 12 to loosen the waste resin. The operator then opens the first ball valve 17 to control the opening degree, so that the waste resin can be controlled to enter the waste resin bucket 19.

The collection funnel (31) is raised and lowered by the second hydraulic lifting device (28) so that the height of the collection funnel (31) matches the height of the loading manhole.

14. A resin loading and unloading device as described in claim 13, characterized in that: The collecting funnel (31) is equipped with a stirrer (32) for stirring the new resin in the collecting funnel (31).

15. A resin loading and unloading device as described in claim 14, characterized in that: The bottom opening of the collection funnel (31) is provided with a second ball valve (33) and a fourth hose (34). The flow rate of new resin is controlled by the second ball valve (33), and the fourth hose (34) is used to transport the new resin into the loading manhole.

16. A resin loading and unloading device as described in claim 15, characterized in that: The second trolley (23) is provided with a second handrail (24), and the second handrail (24) is provided with a second control device (25). The second control device (25) is used to control the start and stop of the first hydraulic lifting device (27), the second hydraulic lifting device (28), the tilting motor (30) and the agitator (32).

17. A resin loading and unloading device as described in claim 16, characterized in that: The bottom of the steel base plate of the second trolley (23) is provided with a second universal wheel (26), and the second universal wheel (26) is provided with a locking device.

18. A waste resin unloading method for a resin loading and unloading device as described in claim 17, wherein the unloading device is used in the free-fall stage of the waste resin unloading process, comprising the following steps: Step 1: The operator loosens the nut on the sealing cap of the unloading manhole (1) so that the sealing cap does not fall off and the waste resin does not overflow. Step 2: The collection bag (13) is tightly fitted between the unloading manhole (1) and the collection bin inlet (8) by the first fastening airbag (14) and the second fastening airbag (15); Step 3: The operator opens the sealing cover of the unloading manhole (1) through the inner glove (16) on the collection bag (13). The waste resin is freely scattered from the unloading manhole (1) into the collection bin (7). During this period, the operator observes the internal condition of the collection bin (7) through the observation window (11). If the waste resin cannot be freely scattered, the operator inserts a tool through the auxiliary tool port (12) to loosen the waste resin. The operator opens the first ball valve (17) and controls the opening degree to allow the waste resin to enter the waste resin bucket (19) in a controllable manner.

19. A waste resin unloading method for a resin loading and unloading device as described in claim 17, wherein the unloading device is used in the suction stage of the waste resin unloading process, comprising the following steps: Step 1: Remove the collection bag (13), close the collection chamber inlet (8), attach the tail end of the second hose (20) to the filter device (9), and insert the top end of the second hose (20) into the waste resin of the discharge manhole (1); Step 2: Attach the top end of the third hose (21) to the filter device (9) and attach the tail end of the third hose (21) to the industrial vacuum cleaner (22); Step 3: Use the first control device (4) to turn on the industrial vacuum cleaner (22) and suck the waste resin into the collection chamber (7); Step 4: Open the first ball valve (17) and control the opening degree to allow the waste resin to enter the waste resin tank (19) in a controllable manner.

20. A novel resin filling method for a resin loading and unloading device as described in claim 17, using the filling equipment in a new resin filling process, comprising the following steps: Step 1: Fix the resin bucket to the first hydraulic lifting device (27) using the resin bucket fixing device (29), and then open the top cover of the resin bucket. Step 2: Push the second handle (24) to move the second trolley (23) to the designated resin filling location; then, restrict the movement of the second trolley (23) by using the locking device of the second caster wheel (26); Step 3: Control the first hydraulic lifting device (27) and the second hydraulic lifting device (28) through the second control device (25) to lift the resin tank and the collection funnel (31) to the required height; Step 4: Control the flipping motor (30) through the second control device (25) to flip the resin bucket to the required angle so that the new resin in the resin bucket is poured into the collection funnel (31); Step 5: Control the agitator (32) to work through the second control device (25) to prevent the new resin from clogging in the collection funnel (31), control the opening of the second ball valve (33) and the position of the fourth hose (34), and control the loading speed and position of the new resin.
