Description

Technical Field

[0001] This utility model relates to the field of benzophenone production technology, and in particular to a spiral tube condenser for benzophenone production. Background Technology

[0002] Benzophenone is an intermediate in the production of ultraviolet absorbers, organic pigments, pharmaceuticals, fragrances, and pesticides. In the pharmaceutical industry, it is used to produce dicyclohexylpiperidine, benzotropine hydrobromide, and diphenhydramine hydrochloride. The product itself is also a styrene polymerization inhibitor and a fragrance fixative, imparting a sweet aroma to perfumes. It can be used in various perfumes and soap fragrances, as well as in the formulation of food flavorings such as almond, peach, cream, and coconut. The production process of benzophenone follows the principle of: benzoyl chloride + benzene → benzophenone + hydrogen chloride. Benzoyl chloride, as a key raw material for benzophenone, is produced through the following process: toluene + chlorine → trichlorotoluene + hydrogen chloride, or trichlorotoluene + benzoic acid → benzoyl chloride + hydrogen chloride. The benzoyl chloride solution is then distilled and condensed to obtain the benzoyl chloride product.

[0003] In the traditional production process of benzophenone, the condenser used for purifying the raw material benzoyl chloride has problems such as low condensation efficiency and high energy consumption.

[0004] The existing Chinese patent CN206300509U describes a graphite condenser for the production of benzophenone. However, in addressing the aforementioned issues, it requires the use of two cooling fans for heat dissipation, resulting in high energy consumption. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a spiral tube condenser for the production and preparation of benzophenone.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

A filter screen is fixedly inserted into the left side of the fixed shell. Several heat dissipation teeth are fixedly connected to the outer edge of the vessel body. A circular tube is fixedly inserted into the right side of the fixed shell. A fixed plate is fixedly connected to the inner cavity of the circular tube. A bearing is fixedly inserted into the fixed plate. A first rotating rod is fixedly passed through the inner cavity of the bearing. Several blades are fixedly connected to the left end of the first rotating rod. A first bevel gear is fixedly connected to the right end of the first rotating rod.

[0008] The inner cavity of the vessel body is provided with a spiral refrigerant pipe. A refrigerant outlet pipe and a refrigerant inlet pipe are fixedly inserted at both ends of the spiral refrigerant pipe, respectively. The ends of the refrigerant outlet pipe and the refrigerant inlet pipe away from the spiral refrigerant pipe are fixedly inserted through the right side wall of the vessel body and are fixedly fitted with flanges. A circular shell is fixedly inserted into the rear side of the refrigerant inlet pipe. Sealed bearings are fixedly inserted into the top and bottom of the circular shell. A second bevel gear is provided at the top of the circular shell. A second rotating rod is fixedly inserted through the inner cavity of the second bevel gear. Two sealed bearings are fixedly inserted through the bottom end of the second rotating rod. Several baffles are fixedly connected to the outer edge of the second rotating rod.

[0009] Furthermore, the top of the vessel body is provided with a vessel lid, and a connecting ring is fixedly sleeved on the outer edge of the vessel body and the vessel lid. Several screws are inserted into the connecting ring, and two connecting rings are connected and fixed by screws.

[0010] Furthermore, a feed pipe is fixedly inserted into the top of the vessel lid near the front side, and a sealing cap is movably fitted onto the top of the feed pipe.

[0011] Furthermore, the bottom of the vessel is fixedly connected to four support legs, which are arranged in a rectangular array. A discharge valve is fixedly inserted into the bottom of the vessel near the center.

[0012] Furthermore, a motor is provided at the top of the lid near the center, and a drive rod is inserted into the top of the inner cavity of the lid. The drive rod is rotatably connected to the lid.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model relates to a spiral tube condenser for the production and preparation of benzophenone. When the refrigerant liquid enters the interior of the circular shell, it impacts the baffle. The baffle drives the second rotating rod to rotate. The second rotating rod drives the first bevel gear to rotate through the second bevel gear. The first bevel gear drives the blades to rotate through the first rotating rod. The blades generate airflow. The airflow enters the interior of the fixed shell through the filter screen. The air inside the fixed shell is finally discharged from the right side of the circular tube. The heat dissipation teeth absorb the heat of the vessel body. When the blades are working, they drive the airflow to dissipate heat from the heat dissipation teeth, thereby improving the cooling performance of the vessel body.

[0016] 2. This utility model provides a spiral tube condenser for the production and preparation of benzophenone. The spiral refrigerant tube of this device can not only cool the reactor body, but also drive the blades to rotate when the refrigerant enters the spiral refrigerant tube, achieving two goals at once. When the blades are working, they drive the airflow to dissipate heat from the heat dissipation teeth, thereby improving the cooling performance of the reactor body. Attached Figure Description

When the blades 17 are working, they drive the airflow to dissipate heat from the heat dissipation teeth 10, thereby improving the cooling performance of the vessel body 1.
