Description

Technical Field

[0001] This utility model relates to the field of coarse filter tank technology, specifically a coarse filter tank for a heterocyclic derivative production system. Background Technology

[0002] In cyclic organic compounds, when the atoms constituting the ring are other than carbon atoms, these cyclic organic compounds are called heterocyclic compounds. The most common heterocyclic compounds are five-membered and six-membered heterocycles and benzo[a] heterocycles, etc.

[0003] Currently, there are certain shortcomings in the treatment stage of wastewater from heterocyclic derivative production. A large amount of wastewater is generated during the production of heterocyclic derivatives, but the loss rate of single-structure filter screens and multi-stage filtration devices used in coarse filtration is extremely high, which can seriously affect the subsequent production of heterocyclic derivatives.

[0004] In view of this, a coarse filter tank for a heterocyclic derivative production system was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A coarse filter tank for a heterocyclic derivative production system includes a filter residue discharge mechanism and a coarse filter mechanism installed within the filter residue discharge mechanism. The filter residue discharge mechanism includes an outer cylinder, an inner cover installed inside the outer cylinder, a slot on the inner wall of the inner cover, and a base fixedly installed at the bottom of the inner cavity of the outer cylinder. The inner wall of the inner cover has evenly distributed slots. The coarse filter mechanism includes an outer filter cover installed inside the inner cover, a plug fixedly installed at the bottom of the outer filter cover, an inner filter cover installed on the top of the plug and located inside the outer filter cover, a filter element inserted between the outer filter cover and the inner filter cover, a reinforcing filter screen fixedly installed on the inner wall of the inner filter cover, an electrode inserted into the middle of the inner cavity of the reinforcing filter screen, an end fixedly installed on the electrode screen, and a funnel-shaped filter screen connected to the end and the top of the outer filter cover.

[0008] In a preferred embodiment, the present invention can be further configured as follows: a top cover is fixedly installed on the top of the outer cylinder, a chassis is fixedly installed on the top cover, a motor is fixedly installed inside the chassis, a sliding column is installed on the motor, a sleeve is movably installed outside the sliding column, and a column is inserted into the sleeve.

[0009] A tie rod is installed at the outer end of the column.

[0010] In a preferred embodiment, the present invention can be further configured such that: a slag discharge pipe is installed in the middle of the outer side of the outer cylinder, and a liquid discharge pipe is installed at the bottom of the outer cylinder;

[0011] The top of the inner cover is fixedly equipped with a liquid inlet pipe, which is adapted to extend through to the outside of the outer cylinder.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0017] 1. This utility model sets up a filter residue discharge mechanism, and sets up a coarse filtration mechanism inside the filter residue discharge mechanism. When the wastewater produced by heterocyclic derivatives is transferred to the gap formed by the inner cover and the funnel-shaped filter screen, the continuously squeezed wastewater will transfer along the funnel-shaped filter screen to the inside of the coarse filtration mechanism. At this time, the waste residue and liquid obtained by forced pressure filtration can be discharged in both directions. During the discharge, the waste residue in the heterocyclic derivatives can be prevented from clogging the filter holes inside the device.

[0018] 2. This utility model installs an electrode column in the middle of the inner filter cover. After the liquid undergoes forced filtration, it enters the inner filter cover and fills the iron-carbon filler in the inner cavity of the reinforced filter screen. This filler can then work with the energized electrode column to perform micro-electrolysis on the filtered liquid, thereby enhancing the filtration efficiency of the waste liquid.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a coarse filter tank for a heterocyclic derivative production system.

[0031] Example 1:

[0032] Combination Figures 1 to 6 As shown, the present invention provides a coarse filter tank for a heterocyclic derivative production system, including a filter residue discharge mechanism 100 and a coarse filter mechanism 200 installed in the filter residue discharge mechanism 100. The filter residue discharge mechanism 100 is used to actively filter the wastewater generated by the heterocyclic derivative, and the coarse filter mechanism 200 is used to perform micro-electrolysis on the filtered liquid.

[0033] The filter residue discharge mechanism 100 includes an outer cylinder 110, an inner cover 130 installed inside the outer cylinder 110, a slot 1301 provided on the inner wall of the inner cover 130, and a base 140 fixedly installed at the bottom of the inner cavity of the outer cylinder 110.

[0034] The inner wall of the inner cover 130 has evenly distributed slots.

[0035] The top of the outer cylinder 110 is fixedly installed with a top cover 1101, a housing 1102 is fixedly installed on the top cover 1101, a motor 1103 is fixedly installed inside the housing 1102, a slide column 1104 is installed on the motor 1103, a sleeve 1105 is movably installed outside the slide column 1104, and a column 1106 is inserted into the sleeve 1105.

[0036] A tie rod 120 is installed at the outer end of the column 1106;

[0037] A slag discharge pipe 1107 is installed in the middle of the outer side of the outer cylinder 110, and a liquid discharge pipe 1108 is installed at the bottom of the outer cylinder 110.

[0038] The top of the inner cover 130 is fixedly installed with a liquid inlet pipe 1302, and the liquid inlet pipe 1302 is adapted to extend through to the outside of the outer cylinder 110.

[0039] The coarse filtration mechanism 200 includes an outer filter cover 210 installed inside the inner cover 130, a plug 2102 fixedly installed at the bottom of the outer filter cover 210, an inner filter cover 2101 installed at the top of the plug 2102 and located inside the outer filter cover 210, a filter element 220 inserted between the outer filter cover 210 and the inner filter cover 2101, a reinforcing filter screen 2103 fixedly installed on the inner wall of the inner filter cover 2101, an pole post 240 inserted into the middle of the inner cavity of the reinforcing filter screen 2103, an end 2301 fixedly installed on the pole post 240, and a funnel-shaped filter screen 230 connected to the end 2301 and the top of the outer filter cover 210.

[0040] Specifically, when the wastewater generated by the heterocyclic derivative is transferred from the inlet pipe 1302 to the gap between the inner cover 130 and the funnel-shaped filter screen 230, the continuously input wastewater will be continuously pressurized in the gap, and the pressurized wastewater will be filtered by the funnel-shaped filter screen 230, and the filter residue will be transferred to the bottom of the gap. The filtered liquid will be transferred along the gap between the inner cover 2104 and the inner filter cover 2101 to the inner cavity of the inner filter cover 2101.

[0041] At the same time, the iron-carbon filler pre-filled in the inner cavity of the reinforced filter screen 2103 can work with the energized electrode 240 to perform micro-electrolysis on the filtered filtrate.

[0042] Example 2:

[0043] Combination Figures 2 to 5 As shown, based on Embodiment 1, the coarse filtration mechanism 200 also includes a sieve plate 250 installed inside the slot 1301, a protective cover 260 movably installed outside the inner cover 130, a guide rod 2601 fixedly installed outside the protective cover 260, and a sliding piece 2602 fixedly installed outside the guide rod 2601 and adapted to fit against the inner wall of the outer cylinder 110.

[0044] An internal cover 2104 is fixedly installed on the outside of the pole post 240, and the internal cover 2104 is located directly above the inner filter cover 2101.

[0045] The inner filter cover 2101 has a cylindrical groove on its inner side, and the reinforcing filter screen 2103 is fixedly installed in the cylindrical groove;

[0046] The other end of the pull rod 120 is mounted on the outer end of the guide rod 2601.

[0047] Preferably, both the outer filter cover 210 and the inner filter cover 2101 have filter holes inside, and the inner wall of the reinforcing filter screen 2103 is fixedly installed with a double layer of mesh to provide anti-overflow protection for the iron-carbon packing. The filtrate that passes through the double layer of mesh and is micro-electrolyzed can be forced to filter by the filter element 220.

[0048] The working principle and usage process of this utility model are as follows: The coarse filtration mechanism 200 is pre-installed inside the inner cover 130. Wastewater generated from heterocyclic derivatives is transferred to the gap between the inner cover 130 and the funnel-shaped filter screen 230 via the inlet pipe 1302. As the wastewater continuously flows in, the pressurized wastewater is squeezed out from inside the funnel-shaped filter screen 230, and the coarsely filtered waste residue is transferred to the bottom of the gap. Then, the motor 1103 is started and operated, and the motor 1103... The drive shaft works with the slide column 1104 to push the column 1106 to move up and down repeatedly. The pull rod 120 is pulled by the column 1106, which drives the guide rod 2601 and the protective cover 260 to move up and down regularly. The protective cover 260 moves up and down along the inner wall of the inner cover 130 at a high frequency. The waste slag transferred into the gap is discharged outward from the groove on the inner wall of the inner cover 130. As too much waste slag accumulates in the gap between the inner cover 130 and the outer cylinder 110, the waste slag can be discharged through the slag discharge pipe 1107.

[0049] The liquid squeezed out from the funnel-shaped filter screen 230 will enter the inner cavity of the inner filter cover 2101 through the gap between the inner cap 2104 and the top of the inner filter cover 2101. Iron-carbon filler will be filled into the inner cavity of the reinforcing filter screen 2103. The electrode 240 will be inserted into the iron-carbon filler. After the electrode 240 is energized, the filtrate after forced filtration can be micro-electrolyzed. The liquid entering the inner cavity of the inner filter cover 2101 will be squeezed out from the reinforcing filter screen 2103. Finally, the squeezed liquid will be filtered twice by the filter element 220 and discharged out from the outer filter cover 210.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
