Description

Technical Field

[0001] The utility model relates to the technical field of chemical product production, in particular to a waste liquid funnel for chemical product production. Background Art

[0002] Pure water changes its original physical or chemical properties after use, and becomes wastewater containing different types of impurities. Chemical wastewater is wastewater such as process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production. In chemical production, before treating the waste liquid, it is necessary to use a funnel to gather it in one place, and then discharge it through the liquid outlet of the funnel for collection and convenient later unified treatment.

[0003] In view of this, Chinese patent number CN212830440U proposes a waste liquid funnel for chemical product production. During use, when the user wants to replace the filter screen, the user can hold the handle and pull out the receiving rod, so that the clamping plate moves to both sides, the limit block leaves the inside of the limit hole, and the spring exerts deformation to eject the filter plate, thereby achieving the effect of quickly removing the filter plate;

[0004] The above technical solution first relies on the elasticity of the spring to pop out the filter plate in the funnel when disassembling and assembling it, and then pulls it out for replacement or cleaning. In this way, during long-term operation, since there are many structural parts connected by the spring, each elastic deformation will cause a certain and considerable vibration to the structural parts, which is prone to loosening and falling off of the structural parts. The pop-up mechanism is installed on the inner side of the funnel, which is very inconvenient for later maintenance. In addition, the spring is easily corroded by the highly corrosive liquid in the waste liquid due to long-term contact with the waste liquid, which affects its pop-up performance and easily reduces the service life of the entire device. In this regard, the present design proposes a waste liquid funnel for chemical product production. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a waste liquid funnel for chemical product production to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model proposes a waste liquid funnel for chemical product production, including a funnel body, a filtering mechanism and a sealing mechanism both installed at the bottom of the funnel body;

[0007] The filtering mechanism includes a connecting seat rotatably installed on one side of the bottom of the funnel body, connecting rods are rotatably provided on both sides of the connecting seat, and one end of the two connecting rods is rotatably connected to the two sides of the outer wall of the funnel body respectively, screw holes are opened on one end of the two sides of the outer wall of the funnel body, and fixing bolts are threadedly connected at the middle position of one side of the two connecting rods, and the outer walls of one end of the two fixing bolts pass through the inner walls of the two connecting rods and are threadedly connected to the inner walls of the two screw holes respectively, a mounting frame is interspersed at the upper edge of the inner wall of the connecting seat, and a filter screen is installed on the inner wall of the mounting frame.

[0008] In one example, a protrusion is provided at the upper end of the inner wall of the connection seat, and the bottom of the mounting frame contacts the top of the protrusion, and a sealing strip is fixedly provided at the edge of the top of the connection seat.

[0009] In one example, the sealing mechanism includes limiting slide grooves opened at the lower edges of both sides of the inner wall of the funnel body, a sealing plate is inserted at the lower edge of one side of the funnel body, and the outer walls at both ends of the sealing plate are respectively slidably connected to the inner walls of the two limiting slide grooves.

[0010] In one example, a scraper is fixedly provided on one side of the inner wall of the funnel body at the upper edge of the two limiting slide grooves, and the bottom of the scraper is in contact with the top of the sealing plate.

[0011] In one example, a handle is fixedly provided on one side of the connecting seat, a drain pipe is inserted through the bottom of the connecting seat, and the inner wall of the drain pipe is connected to the inner wall of the connecting seat, and a sealing valve is installed on one side of the drain pipe.

[0020] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the specification drawings.

[0021] The embodiments are as follows:

[0022] The present utility model provides a waste liquid funnel for chemical product production as shown in Figures 1-4 Figure, which includes a funnel main body 1, a filter mechanism 2 and a sealing mechanism 3 that are all installed at the bottom of the funnel main body 1;

[0023] The filter mechanism 2 includes a connecting seat 201 rotatably installed on one side of the bottom of the funnel main body 1. Both sides of the connecting seat 201 are rotatably provided with connecting rods 202, and one ends of the two connecting rods 202 are respectively rotatably connected to both sides of the outer wall of the funnel main body 1. One ends of both sides of the outer wall of the funnel main body 1 are respectively provided with screw holes 203. The middle positions of one side of the two connecting rods 202 are both threadedly connected with fixed bolts 204, and the outer walls of one ends of the two fixed bolts 204 respectively pass through the inner walls of the two connecting rods 202 and are threadedly connected with the inner walls of the two screw holes 203. An installation frame 206 is inserted at the upper edge of the inner wall of the connecting seat 201. A filter net 207 is installed on the inner wall of the installation frame 206, and the four peripheral edges of the installation frame 206 just contact the inner wall of the connecting seat 201. Installing the filter net 207 and clamping it into the connecting seat 201 and supporting it by the convex block 205 can ensure its stability during filtration, and at the same time, waste liquid is not likely to seep out from the surrounding gaps. At the same time, convex points can be set at the top of the installation frame 206 to facilitate the staff to pull it out of the connecting seat 201 during later replacement. At the same time, when the connecting seat 201 rotates, the connecting rod 202 folds and extends accordingly, so that the connecting seat 201 will not completely drop after being opened, causing waste liquid to drip from the upper opening. When opening the connecting seat 201, the sealing valve 6 can be closed.

[0024] At the upper end of the inner wall of the connecting seat 201, a convex block 205 is provided, and the bottom of the mounting frame 206 is in contact with the top of the convex block 205. At the edge of the top of the connecting seat 201, a sealing strip 208 is fixedly provided. When the connecting seat 201 is rotated and fixed in the screw hole 203 through the fixing bolt 204, the sealing strip 208 just presses against the bottom of the funnel main body 1 to seal the connecting gap thereof.

[0025] Furthermore, the sealing mechanism 3 includes limiting sliding grooves 301 opened at the lower edges on both sides of the inner wall of the funnel main body 1. A sealing plate 302 is inserted through the lower edge on one side of the funnel main body 1, and the outer walls at both ends of the sealing plate 302 are respectively slidably connected to the inner walls of the two limiting sliding grooves 301. When the funnel introduces waste liquid, the sealing plate 302 can be pulled out, so that the channel between the funnel main body 1 and the connecting seat 201 is opened. When replacing the filter screen 207, it can be snapped into it to close the channel between the two.

[0026] On the inner wall of one side of the funnel main body 1, a scraping blade 303 is fixedly provided at the upper edges of the two limiting sliding grooves 301, and the bottom of the scraping blade 303 is in contact with the top of the sealing plate 302. The scraping blade 303 is provided to scrape off the waste liquid and impurities remaining at the upper end of the sealing plate 302 when the sealing plate 302 is pulled out, preventing them from being carried out.

[0027] Working principle: When using the waste liquid funnel for chemical product production in this design scheme, first, the funnel main body 1 needs to be connected to the chemical production equipment, so that the opening area at the top is connected to the liquid discharge area of the equipment, so that the waste liquid directly falls into the inside of the funnel main body 1. Then, after the waste liquid falls onto the lower connecting seat 201 and is filtered by the filter screen 207 therein to intercept some impurities, the waste liquid flows into the drain pipe 5. At this time, opening the sealing valve 6 can discharge and collect the waste liquid for subsequent purification treatment. After filtering impurities for a long time, the user can push the sealing plate 302 on the sealing mechanism 3 to slide it in the limiting sliding groove 301, thereby sealing the lower part of the funnel main body 1, so that the waste liquid no longer flows to the connecting seat 201. At this time, turn the fixing bolt 204 to screw it out of the screw hole 203, and then pull the connecting seat 201 through the handle 4 to rotate it at the bottom of the funnel main body 1 to tilt it, so that its inside is exposed. At this time, the staff can easily take out the mounting frame 206 with the filter screen 207 therein, and then clean or place a new mounting frame 206 with the filter screen 207. Supported by the convex block 205 therein, then rotate the connecting seat 201 so that its top is in contact with the bottom of the funnel main body 1. At this time, insert the fixing bolt 204 to thread it with the screw hole 203 to fix the connecting seat 201 at the bottom of the funnel main body 1, and then pull out the sealing plate 302 to continue leaking and filtering. This design has a simple structure, is convenient for maintenance, and is not easy to cause failures of internal structural parts and cannot be used continuously, improving the overall service life of the device.
