Description

Technical field:

[0002] The utility model relates to a structure used on a discharging pipeline of resin production equipment, in particular to a resin discharging pipeline structure. Background technology:

[0004] The applicant applied for the Chinese patent "Resin Reactor Insulation Device" in August 2020, with announcement number CN213493641U, which includes a plurality of reactor sealed tank bodies penetrated on the second floor slab and a stirring motor arranged on the upper part of each reactor sealed tank body, the output end of the stirring motor is connected with a stirring shaft extending into the reactor sealed tank body and a stirring blade arranged at the lower end of the stirring shaft, a plurality of storage tanks and a feeding pipeline connecting each storage tank and the reactor sealed tank body are arranged on the second floor slab, each feeding pipeline is provided with a conveying pump, a discharge pipeline and a filtering device connected to the discharge pipeline are provided at the bottom of the reactor sealed tank body, the output end branch of the filtering device is connected with a first discharge pipe and a second discharge pipe, and the outer walls of the conveying pump, feeding pipeline, reactor sealed tank body, discharge pipeline, filtering device, first discharge pipe and second discharge pipe are all provided with heating pipes and insulation cotton, as well as metal thin plates.

[0005] Since the resin is easy to condense into agglomerates when the temperature is low and it does not flow for a long time, it is easy to block the discharge pipeline or affect the smooth discharge. Although the discharge pipeline is wrapped with thermal insulation cotton, blockage often occurs when the temperature is low and the discharge does not flow for a long time. In order to solve the blockage of the discharge pipeline, it is necessary to regularly dismantle the discharge pipeline for dredging. However, the existing discharge pipeline is not designed reasonably. When the discharge pipeline is seriously blocked, it is inconvenient to disassemble and assemble, which is time-consuming and labor-intensive.

[0006] Specifically, when disassembling the discharge pipe of announcement number CN213493641U, it is necessary to disassemble the filtering device and the second discharge pipe located above the floor, which makes the disassembly and assembly relatively time-consuming and labor-intensive. Summary of the invention:

[0008] In view of the above problems in the prior art, the purpose of the utility model is to provide a resin discharge pipeline structure, which has a reasonable design, is conducive to reducing the blockage of the discharge pipeline and is convenient for disassembly and assembly of the discharge pipeline.

[0009] The utility model resin discharge pipeline structure is characterized in that it includes a filtering device installed above a floor and a discharge pipe connected to a discharge port at the bottom of the filtering device, the discharge pipe passes through the floor and an upper flange is installed below the floor, the upper flange is connected to a lower flange connected to a discharge main pipe below, the discharge main pipe branch is connected to a first discharge pipe and a second discharge pipe both located below the floor, and the outer peripheries of the discharge main pipe, the first discharge pipe and the second discharge pipe are covered with a thermal insulation cotton layer embedded with an electric heating wire.

[0010] Preferably, the first end of the first discharge pipe is connected to the lower port of the discharge main pipe, the second end of the first discharge pipe is the discharge end, and a first switch valve is provided at the second end of the first discharge pipe.

[0011] Preferably, the above-mentioned second discharge pipe includes a first horizontal section, a first vertical section, a second horizontal section and a second vertical section connected in sequence, the first end of the first horizontal section is connected to the middle part of the discharge main pipe, the second end of the second vertical section is the discharge end, and a second switch valve is provided on the first horizontal section.

[0012] Preferably, the second horizontal section is connected to the lower surface of the floor slab via a clamp.

[0013] Preferably, a rotating sleeve is provided on the first vertical section, which is connected to the connecting rod and the ring in sequence, and a plastic bag for receiving resin residues is inserted into the ring. After the ring is rotated, the mouth of the plastic bag can be located directly below the discharge end of the second vertical section.

[0014] The working principle of the resin discharge pipeline structure of the utility model is as follows: by wrapping the outer circumference of the main discharge pipe, the first discharge pipe and the second discharge pipe with a heat preservation cotton layer embedded with an electric heating wire, when the temperature is low, the heating effect of the electric heating wire on the main discharge pipe, the first discharge pipe and the second discharge pipe can greatly reduce the solidification and agglomeration of the resin in the pipe, and avoid blockage of the discharge pipeline; by connecting the upper flange and the lower flange, it is only necessary to disassemble and assemble the upper flange and the lower flange under the floor slab without disassembling the filtering equipment located on the floor slab, which is simpler to disassemble than the prior art.

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Description of the drawings:

[0022] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0023] The resin discharge pipeline structure of the utility model comprises a filter device 2 installed above a floor slab 1 and a discharge pipeline 3 connected to a discharge port at the lower portion of the filter device 2, wherein the floor slab 1 is a concrete floor slab, the filter device 2 is fixed to the upper surface of the floor slab by a support frame, etc., and the floor slab has a channel for the discharge pipeline 3 to pass through.

[0024] The discharge pipe 3 passes through the floor and an upper flange 4 is installed under the floor 1. The upper flange 4 is fixed to the discharge pipe 3 as a whole. The upper flange 4 is connected to the lower flange 6 connected to the discharge main pipe 5 below. The discharge main pipe 5 is fixed to the lower flange 6 as a whole. The upper flange 4 and the lower flange 6 have corresponding through holes, and bolts are installed in the through holes to achieve locking of the upper flange 4 and the lower flange 6.

[0025] The main discharge pipe 5 is branched and connected to a first discharge pipe 7 and a second discharge pipe 8 both located below the floor slab. Specifically, the first end of the first discharge pipe 7 is connected to the lower end of the main discharge pipe 5, the second end of the first discharge pipe 7 is the discharge end, and a first switch valve 10 is provided at the second end of the first discharge pipe 7. The resin is discharged by opening and closing the first switch valve 10.

[0026] The above-mentioned second discharge pipe 8 includes a first horizontal section 801, a first vertical section 802, a second horizontal section 803 and a second vertical section 804 which are connected in sequence, wherein the first end of the first horizontal section 801 is connected to the middle part of the discharge main pipe 5, and the second end of the second vertical section 804 is the discharge end, and a second switch valve 11 is provided on the first horizontal section 801, and the resin discharge is realized by opening and closing the second switch valve 11; wherein the second horizontal section 803 is connected to the lower surface of the floor slab through a clamp 12, and the clamp 12 has a semicircular arc piece for buckling into the second horizontal section 803, and the two sides of the clamp 12 are locked to the lower surface of the floor slab by bolts.

[0027] In order to achieve heating and insulation of the pipe body, the outer periphery of the main discharge pipe 5, the first discharge pipe 7 and the second discharge pipe 8 is wrapped with a thermal insulation cotton layer 9 embedded with an electric heating wire. The thermal insulation cotton layer 9 is a rectangular sheet, and the electric heating wire is embedded in the rectangular sheet. The rectangular sheet is wrapped around the outer periphery of the pipe body and fixed with tape. The end of the electric heating wire passes through the thermal insulation cotton layer and is connected to the mains to power the electric heating wire for heating.

[0028] In order to receive the residual resin dripping, a rotating sleeve 13 is provided on the first vertical section 801, and the rotating sleeve 13 is connected to the connecting rod 14 and the ring 15 in sequence. A plastic bag 16 for receiving the resin residue is inserted into the ring (it can be a transparent plastic bag, the bag opening of the plastic bag is like being put on a trash can, and the bag opening and the ring are clamped with a clip). After the ring is rotated, the bag opening of the plastic bag can be located directly below the discharge end of the second vertical section. When it is necessary to discharge from the second discharge pipe 8, the rotating sleeve 13 is swung half a circle to make the ring 15 and the bag opening of the plastic bag 16 away from the discharge end of the second vertical section. When the discharge is completed, the rotating sleeve 13, the connecting rod 14 and the ring 15 are swung to make the bag opening of the plastic bag 16 located directly below the discharge end of the second vertical section, so that the residual overflowing resin falls into the plastic bag.

[0029] The reason why the first discharge pipe 7 and the second discharge pipe 8 are set in the present application is that the sizes of the canned containers are different, and the first discharge pipe 7 and the second discharge pipe 8 with different discharge end height positions need to be set; in order to prevent the residual resin from dripping from the discharge end of the first discharge pipe 7, the retractable receiving tray in the background technology CN213493641U can be used (the specific structure is not repeated).
