Description

Technical Field

[0001] The utility model relates to the field of short-chain chlorinated paraffin content detection, and specifically relates to a device for determining the content of short-chain chlorinated paraffin. Background Technique

[0002] The device for determining the content of short-chain chlorinated paraffin is mainly used for determining the content of short-chain chlorinated paraffin. Since short-chain chlorinated paraffins (SCCPs) are a new type of pollutant with persistence, bioaccumulation, and potential biological toxicity, before manufacturing finished products, it is necessary to detect the content of short-chain chlorinated paraffin in rubber and plastic products. The design of this device aims to uniformly crush rubber and plastic products to prevent errors in subsequent determination due to uneven sample crushing.

[0003] The Chinese patent provides a device for determining the content of short-chain chlorinated paraffin, with the publication number CN220251496U, which includes a chassis, a crushing component, and a grinding component; the crushing component includes two crushing rollers and a first transmission mechanism; the grinding component includes a first grinding block, a second grinding block, and a second transmission mechanism for driving the second grinding block to reciprocate. There is a first grinding surface on the first grinding block, with a check groove and a first grinding groove on the first grinding surface. There is a second grinding surface on the second grinding block, with a second grinding groove on the second grinding surface. The minimum distance between the first grinding surface and the second grinding surface is between 1 and 2 millimeters. The utility model includes a crushing component and a grinding component, and the sample will pass through the crushing component and the grinding component in sequence. Therefore, the utility model can automatically perform relatively refined crushing and grinding treatment on leather products. The treated sample can be dissolved relatively completely, making the detection result more accurate.

[0004] The above device can crush rubber and plastic, but usually reacts separately. After the rubber and plastic products are damaged, the crushed materials are then detected, which takes a lot of time and is not efficient. Moreover, harmful gases will appear during the detection process. If the harmful gases are not treated for a long time, it will cause harm to the health of the operator. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for determining the content of short-chain chlorinated paraffin, so as to solve the problems of low efficiency when the existing device determines the content of short-chain chlorinated paraffin and the harm of harmful gases to the health of the operator.

[0006] To achieve the above object, the utility model provides the following technical solution: A device for measuring the content of short-chain chlorinated paraffins, including a working box, wherein a feed inlet is provided at the upper part of the working box, and a crushing motor is fixedly installed inside the working box at a position below the feed inlet. Two crushing drums are meshed and connected to the outside of the transmission shaft of the crushing motor. A support plate is fixedly installed below the crushing drum, and a reaction cup is slidably installed on the other side of the support plate. A feeding structure is arranged inside the working box. The feeding structure includes a feeding plate, the feeding plate is slidably installed on the upper part of the support plate, a funnel is fixedly installed on the upper side of the feeding plate, and a front material receiving plate is fixedly installed on one side of the feeding plate. A rear material receiving plate is slidably installed through the other side of the working box, and a dirt collecting drawer is slidably installed through the lower side of the working box.

[0007] Preferably, the front end of the support plate and the reaction cup are on the same vertical line. Slot holes are provided on the outside of the feeding plate, and the funnel is adaptively matched with the slot holes.

[0008] Preferably, the feeding plate and the front material receiving plate are connected by two columns. The feeding plate is higher than the rear material receiving plate, and the outside of the rear material receiving plate is hollowed out.

[0009] Preferably, a filtering structure is arranged at the rear of the working box. The filtering structure includes a driving motor, a blowing box is fixedly installed at the front end of the transmission shaft of the driving motor, a suction pipe is fixedly installed below the blowing box, and a front air duct is fixedly installed on one side of the blowing box. A reaction box is fixedly installed between the front air duct and the working box. A rear air duct is fixedly installed at the upper part of the reaction box, and a storage drawer is slidably installed through one side of the reaction box. A sponge is fixedly installed inside the storage drawer.

[0010] Preferably, the suction pipe and the reaction cup are on the same vertical line, and the front end of the suction pipe is in the shape of an inverted cone. Both the front air duct and the rear air duct are installed through the upper part of the reaction box, and slot holes are provided through the front end of the storage drawer.

[0011] Preferably, a number of long rods are fixedly installed on the outside of both crushing drums. The reaction cup, the feeding plate and the funnel have the same diameter.

[0012] Preferably, grooves are provided on the outside of the front material receiving plate, the rear material receiving plate and the dirt collecting drawer. The dirt collecting drawer is adaptively matched with the working box.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1) The device for determining the content of short-chain chlorinated paraffins can move the feeding plate forward or backward by controlling the front supporting plate, so that the crushed materials inside the funnel on the feeding plate move forward. When the crushed materials move to the front end of the supporting plate, they fall into the reaction cup and react with the reaction solution. When the rear feeding plate is controlled, the reaction cup can be moved forward or backward, so as to flexibly install and disassemble the reaction cup, and the scattered waste can fall through the hollow of the rear feeding plate to reach the dirt collecting drawer and be discharged by the dirt collecting drawer. By flexibly controlling the front supporting plate, the rear supporting plate and the dirt collecting drawer, problems such as time-consuming and laborious distribution reaction can be solved, providing high efficiency for the determination of the content of short-chain chlorinated paraffins.

[0015] 2) The device for determining the content of short-chain chlorinated paraffins can discharge harmful gases outward through the driving motor, and a reaction box is installed between the front air duct and the rear air duct. The filtering solution in the sponge inside the reaction box reacts with the harmful gases to achieve the purification treatment of the harmful gases. Moreover, the storage drawer inside the reaction box can be pulled out to replace the sponge. When in use, the harmful gases can be purified by controlling the driving motor, avoiding the threat to human health caused by the harmful gases. Description of the Drawings
