Description

Technical Field

[0001] This utility model belongs to the field of material screening technology, and specifically relates to a sulfur powder sampling and screening device. Background Technology

[0002] With the continuous development of the times, sulfur powder is widely used in various industries. Sulfur powder is fine and easily carries static electricity. During the production process, to ensure the product particle size is up to standard, frequent sampling and sieving of the finished product are required. Traditional sieving relies on manual sieving using test sieves. Because the pulverized sulfur powder has a low bulk density and carries static electricity, manual test sieves cannot sieve it properly. Usually, the powder is manually rubbed and squeezed on the test sieve surface to force it through. This operation can lead to adverse consequences for the operator's health, as the sulfur powder is very fine and the dust generated during sieving and collection may affect the operator's health. Furthermore, common sieving machines often require stopping the machine before dust collection to prevent leakage, greatly reducing work efficiency. Utility Model Content

[0003] To address the problems of human health impact and low screening efficiency associated with manual screening of pulverized sulfur powder, this invention provides a sulfur powder sampling and screening device that effectively reduces human contact with dust and debris and efficiently harvests the pulverized material.

[0004] This utility model is achieved through the following technical solution: A sulfur powder sampling and screening device includes a feed hopper, a collection hopper, a dust collection hopper, and a blower; The top of the feed hopper is fitted with a screen barrel, and a screen is installed inside the screen barrel; an exhaust pipe is connected to the side of the feed hopper. The top of the collection hopper is connected to a dust collection hopper; the side of the collection hopper is connected to an air outlet pipe. The dust collection bin contains several cloth bags, which are arranged vertically with their openings located at the top of the collection bin; a door is provided on the side of the dust collection bin. The blower is connected to the exhaust pipe and the outlet pipe respectively.

[0005] The working principle of this utility model is as follows: When the operator wants to start screening, first add the sample to the sieve bucket, then start the blower. The suction force of the blower creates a negative pressure in the feed bucket, and the sample in the sieve bucket is drawn into the feed bucket by the negative pressure and then sucked into the blower. With the air force, it is blown into the collection bucket and finally collected by the cloth bag, thus achieving screening. After the cloth bag is full, open the cylinder door and replace it with a new cloth bag to continue collecting.

[0006] As a further improvement of this utility model, the top of the collecting cylinder is provided with a partition, and a connecting pipe is provided on the partition to connect with the bag opening of the cloth bag. A telescopic column is provided inside the connecting pipe, and a baffle is provided at the bottom of the telescopic column. The dust collection bin is equipped with a telescopic rod at the top and a hook at the bottom to hook the bottom of the cloth bag; the dust collection bin is also equipped with a fixed pulley at the top, and the connecting line is connected to the hook and passes through the fixed pulley to connect to the telescopic rod.

[0007] As more and more material is collected in a bag, the bag becomes heavier and heavier. When the weight reaches a critical point, it causes the telescopic rod to stretch vertically, which in turn causes the hook at the bottom of the telescopic rod to move vertically. The connecting line on the hook lifts the telescopic column upward through the fixed pulley, which in turn causes the cover baffle to cover the inlet of the connecting pipe, preventing material from continuing to enter the bag.

[0008] As a further improvement of this utility model, the dust collection bin is equipped with a warning light on the top, and the telescopic rod is electrically connected to the limit switch and then connected to the warning light.

[0009] When the bag is full of material, the telescopic rod extends to its maximum length under the action of gravity and triggers the limit switch, which illuminates the warning light, thus reminding the user to replace the bag.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a blower to create negative pressure inside the feeding hopper, causing the material to enter the feeding hopper after being screened by the screen, and finally be blown into the collection hopper by the blower. The material is then collected by a cloth bag inside the collection hopper, which greatly reduces the possibility of operators coming into contact with dust, realizes automated screening, and improves screening efficiency.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are all conventional technical means in the art. Example

[0015] like Figure 1-2 The sulfur powder sampling and screening device shown includes a feed hopper 1, a collection hopper 2, a dust collection hopper 3, and a blower 12; The top of the feed hopper 1 is fitted with a screen 4, and a screen 6 is provided inside the screen 4; the side of the feed hopper 1 is connected to an exhaust pipe 8. The top of the material collection hopper 2 is connected to a dust collection hopper 3; the side of the material collection hopper 2 is connected to an air outlet pipe 13. The dust collection bin 3 is provided with several cloth bags 17, which are arranged vertically with their openings located at the top of the collection cylinder 2; the dust collection bin 3 is provided with a cylinder door 15 on its side; The blower 12 is connected to the exhaust pipe 8 and the exhaust pipe 13 respectively.

[0016] The working principle of this embodiment is as follows: When the operator wants to start screening, first add the sample to the sieve hopper 4, then start the blower 12. As the blower 12 draws in, it creates a negative pressure inside the feed hopper 1. The sample in the sieve hopper 4 is drawn into the feed hopper 1 by the negative pressure and then sucked into the blower 12. With the air force, it is blown into the collection hopper 2 and finally collected by the cloth bag 17, thus achieving screening. After the cloth bag 17 is full, open the cylinder door 15 to replace it with a new cloth bag 17 and continue collecting. Example

[0017] This embodiment is a further improvement based on Embodiment 1, as detailed below: The top of the collecting cylinder 2 is provided with a partition 14, and a connecting pipe 16 is provided on the partition 14 to connect with the bag opening of the cloth bag 17. A telescopic column 21 is provided inside the connecting pipe 16, and a baffle 5 is provided at the bottom of the telescopic column 21. The dust collection bin 3 is equipped with a telescopic rod 18 at the top and a hook 19 at the bottom to hook the bottom of the cloth bag 17. The dust collection bin 3 is also equipped with a fixed pulley 20 at the top. The connecting line 10 is connected to the hook 19 and then passes through the fixed pulley 20 to connect to the telescopic rod 18.

[0018] The working principle of this embodiment is the same as that of embodiment 1. As more and more material is collected in a certain cloth bag 17, the weight of the cloth bag 17 becomes heavier and heavier. When the weight reaches the critical point, it drives the telescopic rod 18 to stretch in the vertical direction, thereby driving the hook 19 at the bottom of the telescopic rod 18 to move vertically. The connecting line 10 on the hook 19 lifts the telescopic column 21 upward through the fixed pulley 20, which in turn drives the cover baffle 5 to cover the inlet of the connecting pipe 16, preventing the material from continuing to enter the cloth bag 17. Example

[0019] This embodiment is a further improvement based on embodiment 2, as detailed below: The dust collection bin 3 is equipped with a warning light 7 on its top, and the telescopic rod 18 is electrically connected to the limit switch and then connected to the warning light 7.

[0020] The working principle of this embodiment is the same as that of embodiment 2. When the cloth bag 17 is full of material, the telescopic rod 18 extends to its maximum length under the action of gravity and triggers the limit switch, so that the warning light 7 lights up, thereby reminding the user to replace the cloth bag 17.
